Which screen is better than ips or oled


Matrix VA, MVA and PVA occupy an intermediate position between TN and IPS in terms of image quality and price. Compared to TN, they have wider viewing angles and more accurately convey the depth and naturalness of color, compared to IPS they are cheaper. However, these types of screens are not widely used. They are used in the production of monitors for PCs and budget TV series.

Let there be light

There are several types of LED LCD backlight technology. They differ in color, the location of the LEDs on the LCD panel and the way they dim.

  • A type of backlight with only white LEDs is called WLED. It is relatively simple in structure, but has a limited color gamut.
  • RGB LED backlighting, built on red, green and blue LEDs, covers a wider range of colors than WLED, but is prone to degradation (diodes of different colors fade at different rates), heavy and burdensome in price.
  • GB-R LED is the next step in the development of LCD, where instead of a white LED, a combined green blue, coated with a red phosphor (self-luminous pigment) is used. This solution allowed us to cover 99% of the RGB palette and get rid of the disadvantages of RGB LED. GB-R LED technology used in AH-IPS and PLS matrices.
  • RB-G LED is a variation of the previous type of backlight. Instead of blue-green LEDs, there are red-blue LEDs covered with green phosphor.

which, screen, better, oled

On the basis of WLED, another LCD standard has been developed. QDEF, where blue diodes are used instead of white, and the red and green colors are formed by a coating of quantum dots (crystals that glow under the influence of electricity) applied to a sheet of plastic. QDEF displays reproduce up to 60% of the shades perceptible to the human eye, which is several times higher than what WLED can achieve. And in terms of energy costs and price, WLED and QDEF screens are approximately equivalent.

QDEF is also one of the versions of QLED (Quantum-dot Light Emitting Diode) technology, which is based on quantum dot LEDs.

By the location of the light-emitting elements on the LCD panel, the following types of LED backlighting are distinguished:

  • Edge LED. LEDs are arranged linearly around the perimeter of the screen. This is economical, but does not provide uniform lighting and acceptable contrast levels.
  • Direct LED. An array of LEDs is distributed across the entire display area. This technology gives a more realistic picture, but panels of this type consume a lot of energy and have a significant thickness, which makes them difficult to install on ultra-thin TVs.
  • Side illumination. the diodes are located only at the edges of the screen, and the lighting is provided by the light guides connected to them. This type of backlighting is considered optimal, as it provides uniformity comparable to Direct LED, and at the same time is devoid of its disadvantages.

Each of the three types of backlighting is divided into 2 more. with support for local dimming (Local Dimming) and dynamic contrast ratio (DCR) or no support. Local Dimming and DCR screens look more realistic.

TFT vs IPS. IPS Properties and Versions

“But IPS screens are definitely better than TFT, it’s not for nothing that they write about this on the forums !?” And again, those who write in this way did not guess. IPS is a kind of TFT. Same as TN, PLS, VA, MVA, PVA and others. TFT screens are sometimes mistakenly called TN (Twisted Nematic) displays, which really do not shine with picture quality. of all TFT options, they have the worst color rendition, the lowest brightness and contrast, and very limited viewing angles. On the other hand, TN screens are characterized by low cost, fast response and high refresh rate.

IPS (In Plane Switching) is the next step in the development of active matrix technology, which eliminated the main disadvantages of TN. Changing the position of the crystals and the voltage points on the cell caused the black to become truly black, and when viewed from the side, the colors remain the same as when viewed from the front. In addition, IPS screens noticeably improved color reproduction and increased overall brightness and contrast, but the response speed compared to TN, on the contrary, decreased.

Today, IPS is being developed in parallel by 3 companies. Panasonic (took over the “baton” from the developer of the first version. Hitachi), NEC and LG. Each version and generation of this technology has its own characteristics and names.

  • The Hitachi and Panasonic lineup includes: IPS (Super TFT), S-IPS (Super-IPS), AS-IPS (Advanced super-IPS), IPS-Pro (IPS-provectus, IPS alpha, IPS alpha next gen).
  • NEC’s developments are named: SFT (Super fine TFT), A-SFT (Advanced SFT), SA-SFT (Super-advanced SFT), UA-SFT (Ultra-advanced SFT).
  • LG products are called: S-IPS (Super-IPS), AS-IPS (Advanced super-IPS), H-IPS (Horizontal IPS), E-IPS (Enhanced IPS), P-IPS (Professional IPS), AH-IPS (Advanced high performance IPS).

Samsung is developing its own version of IPS called PLS (Plane to Line Switching).

LED Matrix.

All developers are improving technology in the same directions. This is a decrease in response time, an increase in contrast, depth and naturalness of color, an improvement in viewing angles, elimination of color distortions, a decrease in power consumption, and most importantly. a reduction in the cost of production of matrices. Computer monitors with IPS screens in recent years are already “treading on the heels” of TN in terms of response speed and can be used not only for professional graphics, but also for dynamic games.

Most users, except, perhaps, professionals in the field of graphics and design, will not notice the differences in the picture on IPS-displays of different brands, but there are also quite significant differences between their budget and top-end versions. The highest image quality is reproduced by LG’s P-IPS and AH-IPS matrices. They are the most expensive.


LCD, TFT, LED, AMOLED and other “ice” are just abbreviations, and the differences between them are a chasm. over, some of these concepts are incomparable. So, no one will tell you which TV is better: LCD or LED, since LCD (Liquid Crystal Display) is a liquid crystal display or just LCD, and LED (Light Emitting Diode) is one of the types of its backlight (LED). That is, the TV can be LCD and LED at the same time.

The structural diagram of the LCD screen with LED backlight is shown in the figure below:

LED backlighting, in contrast to the outdated fluorescent (CCFL), provides an even distribution of light over the surface of the screen and a higher level of brightness. Plus, it uses less energy and lasts longer.


“What about a TFT TV? Is it better than LCD or worse? ” Neither, because TFT (Thin Film Transistor) is an active matrix LCD, a kind of LCD. Active Matrix is ​​a display color management system where each pixel is regulated by its own group of thin-film microtransistors.

Unlike a passive matrix, where the shade of pixels is adjusted linearly (by lines and columns), the active one reacts 5-6 times faster to changing the picture, has a higher brightness, contrast and viewing angles, and also consumes less energy.

LCD screens of all modern TVs, monitors, smartphones and tablets have an active matrix, so it is inappropriate to compare LCD and TFT in relation to these devices.


Although the concept of OLED is consonant with LED, it has practically nothing in common with it. OLED (Organic Light Emitting Diode) is a display technology based on the properties of organic semiconductors. elements that can emit light when exposed to current. Each sub-pixel on an OLED screen is a separate organic light-emitting diode (OLED). Unlike LCD, OLED panels do not need backlighting as they light up with each dot.

Other properties and features of OLED versus LED:

  • Low thickness and weight by reducing the number of layers.
  • Unlimited viewing angles.
  • Uniform illumination.
  • Minimum response time.
  • Flexibility.
  • Significantly higher brightness, contrast and color saturation.
  • Low sensitivity to external temperatures, but high to moisture.
  • Short service life and tendency to degradation: blue diodes burn out 3 times faster than red and almost 10 times faster than green.
  • Dependence of resource depletion on screen brightness. the higher it is, the faster fading occurs.
  • Sensitivity to mechanical damage. A minor defect leads to a complete failure of the screen.
  • Flicker by applying PWM (Pulse Width Modulation) to control brightness. OLED screens use PWM optional.
  • High price.

AMOLED (Active Matrix Organic Light Emitting Diode) is an active matrix based on organic light-emitting diodes, a combination of TFT and OLED technologies, where the latter is used as a backlight. Accordingly, AMOLED screens have the properties of both.

AMOLED technology has found wide application in the production of touchscreen displays for mobile devices. And not only she, but also the branches of her development. Super AMOLED and Super AMOLED plus.

The difference is simply AMOLED from Super. lies in the absence of the second air gap between the surfaces of the touchscreen and the matrix, which increases the clarity of the picture. And from Super AMOLED plus. in the number and location of subpixels (color components of the pixel). In the latter, there are 50% more of them and they are placed denser.

AMOLED, OLED, IPS, TFT, etc.: how these types of displays differ and which one is better

If a person is “greeted by his clothes, but escorted by his mind,” then a TV, computer monitor, smartphone and tablet are greeted on the display. And they often see off too. When buying such a device, it is not always possible to assess the beauty and other properties of its screen with one’s own eyes, because many transactions are made via the Internet. But if you know what 3 letters mean, then it is easy to get an idea of ​​the display of the device, even without seeing it.

No, these are not at all the letters that are written on the fence. And sometimes there are more than 3 of them. For example, LED, LCD, IPS, TFT, OLED, QLED, AMOLED. All these are screen manufacturing technologies that determine their characteristics. Let’s talk about LED, AMOLED, QLED, OLED displays and how they differ from IPS, TFT, LCD, etc.

OLED or IPS. what to choose?

We analyze how these types of displays differ and which is better.

Recently, you can often see advertisements for innovative OLED TVs or monitors based on IPS-matrix. What is the difference between OLED and IPS displays, and is there an undisputed leader among them?

For clarity, let’s take 2 iPhone X models with different monitors and compare them: the iPhone XR, which has an IPS display, and the iPhone XS Max with an OLED display.


IPS and OLED have fundamentally different designs. IPS has a layer that diffuses light. On top of the light scattering layer, there is a layer of liquid crystals that transmits it or does not transmit it. Under the influence of voltage, these crystals can practically not transmit light (as in the dark parts of the screen), transmit only red (or green, yellow, any other colors), or transmit all colors. in this case, we see white (a point in the center of the screen ).

As for the OLED display, it consists of thin films that do not need an external light source. they glow on their own. On such displays, every single pixel can be illuminated. On the screen shown in the photo, only the dot in the center of the display glows, not the whole.

Consequently, OLED is more energy efficient because it does not need to constantly light up the entire screen. Plus, OLED blacks are deeper and more natural.

On the other hand, there is no pure white on an OLED display and it turns out that white is better on IPS.

Eye fatigue

When using a smartphone with an IPS-display, eyes get tired less. What is the reason?

Regarding dimming, in IPS everything is relatively simple: the lower layer gives more light, and the brightness rises. In OLED, pixels are constantly on and off. The more often they light up, the higher the brightness becomes. If they start to light up and go out too slowly, we begin to notice flickering.

READ  How To Turn On The Screen On A Laptop

Some people see this flickering (using an OLED device can cause headaches for them), while others just feel eye strain.

Life time

IPS screens can work for years without turning off, unlike OLED. Why is this happening?

Both displays most often have pixels in three colors: red, green, and blue. Blue pixels will fade faster (in

50,000 hours). The brighter the phone, the less pixels will live.

Consequently, the lifespan of an OLED display is theoretically shorter than an IPS, and manufacturers have to come up with various ways to extend the lifespan of OLED devices.

History of creation

IPS (English in-plane switching) in its modern sense was developed in 1996 by NEC and Hitachi. Even then, the screen production technology was close to the modern one in terms of color rendering and viewing angles (178 °).

OLED (organic light-emitting diode) began to be used in phone production in 2004 by Samsung. Initially, the OLED display did not have much success due to too sharp settings, but now, of course, this problem no longer exists. the color reproduction is natural and comfortable for the eyes.
OLED is a newer and more expensive technology in terms of production, so not all companies can afford it.

What else?

  • IPS has more stable power consumption, but it takes longer to respond to action. Therefore, if you love mobile games, you should opt for the OLED display.
  • OLED displays have pixels closer to the surface of the screen, so the image is less distorted at angles than IPS.
  • Smartphones with IPS displays cannot be flexible (like the Samsung Galaxy Fold).
  • IPS resists moisture better.
  • Contrast is much higher on OLED screens.
  • OLEDs have a wider range of possible brightness.

So, obviously, in order to make a choice in favor of one or the other type of display, you need to clearly understand what is more important to you: whether the color rendition, whether it is quick response to action or resistance to moisture. It is necessary to consider all factors when purchasing a device with an OLED or IPS screen, so as not to be disappointed with the purchase later.

What are IPS and AMOLED technologies

You can find many different names for technologies that are implemented in screens and displays. But the basic ones are OLED and LCD. LCDs are liquid crystal matrices, the main properties of crystals of which are anisotropy and fluidity. By changing the orientation of the crystals, the desired pixel color is obtained. All LCD screens require a backlight source. IPS, PLS and other modifications relate specifically to LCD.

But OLED uses organic light-emitting diodes instead of liquid crystals, which do not need backlighting. OLED is divided into a passive matrix and an active matrix by the way it drives the diodes. Hence AMOLED. Active Matrix OLED, and passive ones are practically not used in smartphones. It turns out that the main difference between IPS and OLED is the principles of building their display matrix.

Although the first phones with an IPS matrix appeared in the mid-90s, their mass production began only a few years ago and now occupies a strong position in the market. AMOLED is a technology produced by Samsung. It was originally used in televisions. It has such a rich color reproduction that the image loses its naturalness, which is why it has a fan and critics. As it improved, it became known as Super AMOLED. Now you can take a closer look at the advantages and disadvantages of both types of displays.

Which technology is better: IPS or AMOLED? Expert opinion

When choosing mobile phones, the buyer is primarily interested in the characteristics of hardware and firmware, design, build quality of the device. But he often does not pay attention to the technologies used to make the screen. Perhaps many did not even think about the difference between them. Today the main technologies are IPS and AMOLED. Let’s try to figure out what is better than IPS or AMOLED, what are their main differences or similarities.

Advantages and disadvantages of IPS matrices

Of the advantages of this screen technology, the following can be noted:

  • natural color reproduction: colors are not artificially enhanced, so a dull picture will look dull, but a bright picture will not overly cut your eyes. Such displays are good for those who work with photographs and images;
  • transfer of white color without parasitic shades;
  • colors are not distorted when viewed from a different angle;
  • cheaper production technology;
  • no problem of LED burnout;
  • large viewing angle. 178 0.

Despite all the positive qualities of IPS, the technology also has disadvantages, such as:

  • high energy consumption due to the illumination of the entire matrix;
  • longer response time;
  • not a very high level of contrast;
  • black is not completely black, it has an extraneous shade.

Advantages and disadvantages of AMOLED matrices

Now let’s look at the advantages and disadvantages of amoled displays. The advantages are as follows:

  • unlike IPS, pure black is obtained here due to the highlighting of individual pixels;
  • quick response;
  • less energy consumption, as each pixel is highlighted, not the entire display. Because of this, the smaller screen thickness.
  • very bright colors that seem unnatural. This can be both a plus and a minus, depending on the perception. But such screens tire the eyes faster;
  • more expensive production technology;
  • colors fade over time;
  • it is very difficult to look at the picture in bright light;
  • whites may have yellowish or bluish tints, which may distort the color of the entire image.

A kind of technology. super amoled. consists in the absence of an air gap between the sensor and the matrix, which reduces the amount of reflected light. However, this innovation has caused complaints from customers due to color distortion. As you can see, both technologies have good and not so good qualities. Next, let’s try to figure out in which situation and which is preferable to choose.

What is the difference between displays

So, what is the difference between competing technologies. Which display to choose: IPS, AMOLED or Super AMOLED.

Summing up, we can say that the main difference lies in the following parameters:

  • color rendering. It will be more natural in IPS;
  • energy consumption. Below in AMOLED. But in the case of too light images, this advantage is lost and is practically compared with IPS;
  • life time. Longer in IPS, due to the lack of LEDs;
  • screen thickness. Less for AMOLED;
  • cost. Below in IPS;
  • viewing angle. Equally good in both matrices.

These differences may be completely invisible or insignificant for the user.

Which is better

Comparison of AMOLED and IPS showed that both technologies have advantages and disadvantages, therefore, which screen is better to choose. AMOLED or IPS, depends more on the goals and preferences of the user. If the phone is purchased for a long service life, then it is better to choose IPS, since after a few years in AMOLED LEDs will start to fade, which will lead to distortion of the picture colors.

With prolonged use of amoled, for example, with frequent reading or viewing, there is visual fatigue from an overly bright image. But on the other hand, its contrast is better. At the same time, amoled is more expensive, but its display is thinner, and it also consumes less charge. Characteristics such as responsiveness and visibility of the pixel grid are very subtle. In any case, both technologies will find their admirers. Development in this area all the time offers new improvements, in which the existing shortcomings are gradually eliminated.

Brightness and features of work

Mi 8 SE IPS screen (left), Mi 8 AMOLED screen (right)

Smartphone screens are completely identical in size and resolution, differing only in the size of the “cutout” for the front camera. This allows you to see the parameters in detail. And we will do this not in laboratory, but in combat conditions of complex lighting, so it is clearer and more interesting. Especially when it comes to the most important: brightness, backlight uniformity and image clarity.

AMOLED screen Mi 8

As you can see in the photo above, even the OGS screen (without an air gap) of the Mi 8 SE glares more. The reason. 3 layers of the screen: protective glass, a layer of liquid crystals, backlight. A more uniform backlighting allows for a higher apparent color density, which looks “fatter” on the Mi 8 with AMOLED. The thing is that brightness, contrast and dynamic range are really higher even at similar levels.

IPS screen Mi 8 SE

If you pay attention, the fonts on the AMOLED screen are clearer and sharper. over, in cases with complex colors, dull shades. However, the background areas on the liquid crystal display are better developed, soft transitions are brighter and more distinguishable.

What screens are there?

The structure of the main types of displays

The displays of modern electronics have evolved constantly. Cathode ray tubes became extinct, replaced by liquid crystals and LEDs. Today, at least 4 large classes of screens coexist on the market at the same time with their own manufacturing technology and picture display features.

TN (Twisted Nematic). The most affordable display that uses liquid crystals to create an image, the image on which becomes visible thanks to the backlight from incandescent lamps. This class is deprecated, although it has no analogues in a number of use cases.

STN (Super Twisted Nematic), as well as Double STN and DSTN (Dual-ScanTwisted Nematic). Continuation of LCD screens with improved parameters. On sale are found under the name of regular TN.

IPS (In-Plane Switching). A type of LCD that uses a more uniform and brighter LED backlight.

VA (Vertical Alignment). Philips proprietary matrix that combines the advantages of IPS and TN-matrices. The characteristics are somewhere in between, as well as advantages and disadvantages. Not applicable in compact electronics.

AMOLED (Active Matrix Organic Light-Emitting Diode). Instead of a two-layer matrix “liquid crystals backlight”, the technology uses one layer of organic light-emitting diodes: they give both color and light.

Color: where is correct?

Mi 8 SE IPS screen (left), Mi 8 AMOLED screen (right), cold color scheme

With colors of different types of screens, things are not as smooth as they seem. It is widely believed that AMOLED has a toxic gamut, IPS lends itself better to adjustment and offers the most accurate gamut. In practice, everything is confirmed by the human eye and turns out to be exactly the opposite when studied through optical devices.

Mi 8 SE IPS screen (left), Mi 8 AMOLED screen (right), standard color scheme

It’s all about the insidiousness of the protective glass coatings: due to the oleophobic coating, the developers managed to “soften” the white on the AMOLED panel of Mi 8. The same coating from greasy marks on the Mi 8 SE glass gives the opposite effect, seriously distorting the gamut into a cold spectrum. This behavior occurs with any color gamut setting. What’s the matter?

Mi 8 SE IPS screen (left), Mi 8 AMOLED screen (right), warm color scheme

The screen of the Mi 8 SE glares too much due to the split structure, whereas the gamma of the Mi 8 does not need to be corrected. The lack of interlayers allows the display to show what the developers intended, regardless of external conditions. The macro photographs only confirm what has been said. Adjusted for overall brightness, the brightness levels of the Mi 8 are always higher.

Let’s look at an angle

Mi 8 SE IPS screen: transparent colors, correct white

A closer examination at close range changes the position of liquid crystal matrices: now AMOLED glares, IPS does not. Only then it becomes clear that there is no real difference between the white balance of the screens, it all depends on external distortions and perception. Choosing a different lens and shooting conditions will turn the situation in a different direction. Therefore, it is the structure and refresh rate that will determine the quality of color reproduction.

AMOLED screen of Mi 8: rich colors, correct black

In this case, AMOLED will have a hard time, since the increase in shooting speed will leave white color for IPS, and rainbow color for an OLED matrix. Returning to the title, I have to note: there are no visible problems when changing the viewing angle for matrices of both types. Unsurprisingly, the refresh rate and pixel density are too high. At low resolutions, IPS will show black issues precisely at an angle.

Which display is better: OLED or IPS

AMOLED screens are becoming more affordable, replacing conventional liquid crystal displays, even in cheap technology. Is it good? Let’s try to understand the theory, and then test it in practice. Everything is very ambiguous. You will definitely be surprised after reading this material.

Artifacts that are not visible

AMOLED screen Mi 8: Pentile

Macro shots, even at maximum brightness, reveal the shortcomings of each type of display. The OLED array used by Xiaomi demonstrates its structure. The eye usually does not notice the uneven brightness of the pixels, but the white background and the camera show a defect. The same Pentile, which is typical for all similar screens, can be visible or not. But anyway, this structure is used in all mainstream displays.

Mi 8 SE IPS Screen: Visible Pixel Grid

The liquid crystal matrix shows its structure in any color, at any brightness. But the pixel grid does not strain the eyes, in contrast to the uneven brightness. In addition, raising the backlight frequency beyond 60 Hz virtually eliminates the main disadvantage of the IPS panel. With AMOLED, this trick is harder, still annoyingly affecting the eyes.

IPS features to be aware of

The basic structure of the IPS-screen

Availability. Mass production is doing its job, allowing you to use the TN-matrices of the past to create IPS.

Color rendering. Liquid crystals can display a wide variety of colors, and LED complements the capabilities perfectly by accurately illuminating the current pixel position. In addition, the experience of engineers has made it possible to turn IPS-matrices into the most accurate displays. True, until it comes to black.

Power usage. Liquid crystals that form a picture on an IPS screen consume almost no current. The main consumer of energy is the backlight diodes.

Durability. Liquid crystals are not subject to aging and wear. Backlight LEDs also have a huge resource.

Illumination unevenness is clearly visible

Nevertheless, IPS has a lot of theoretical and factual drawbacks:

Black color. A TN matrix cannot have a pure black color: under the layer of a color emitter there is still a backlight that forms a trail of the image.

Low contrast. Low black depths do not accurately separate grayscale, they are mixed. In addition, the backlight has a narrow luminance range, which results in a low difference between the brightest and darkest pixels.

Long response time. In this case, the problem is entirely in the backlight: its LEDs simply do not have time to quickly respond.

How and what we will test?

For the purity of the experiment and the most correct comparison of 2 types of screens, we will test smartphones. They are the ones who use the highest quality matrices: small displays are easier to make than huge TV panels. The subjects will be 2 Xiaomi smartphones: in the left corner of the ring Mi 8 with an AMOLED matrix, in the right corner. a simplified Mi 8 SE with an IPS screen. The belonging of devices to the same manufacturer and generation gives a rough idea of ​​the development of technologies in a cross-section. The more affordable Mi 8 SE is cheaper, not least thanks to the screen, but in order to maintain its position, the sub-flagship must be equipped with the highest quality matrix. No worse than the flagship.

What are IPS matrices

Liquid crystal IPS displays are manufactured using a special technology based on a new way of positioning the control electrodes. In these matrices, they are located in one plane parallel to the screen. Thanks to this change, the display image has become brighter and more saturated. Smartphone manufacturers immediately applied this development in the manufacture of screens for their gadgets.

  • A properly configured IPS display has excellent color reproduction. Each pixel of the matrix reproduces color as accurately as possible, making the image rich and realistic.
  • Stable power consumption. Unlike LED organic matrices, liquid crystals practically do not consume electric current. Only the backlight needs power, so the load is fixed. This allows you to optimally select the battery and optimize the battery life when watching movies, playing games or surfing the Internet.
  • Long service life. IPS matrices based on liquid crystals have minimal wear, therefore they are durable.
  • Cost. LCD displays made using IPS technology belong to an affordable price category, in comparison with many modern solutions, while providing good image quality.

Despite the numerous advantages of IPS matrices, they also have certain disadvantages:

  • Long response time. Since each pixel of the IPS display is not excited by its own power supply, but depends on the LED backlight, this factor significantly slows down the reaction of the crystals to the signal.
  • Low contrast. The brightness ratio of the lightest to darkest pixel in IPS displays is inadequate compared to current OLED solutions.
  • Unsaturated black color. Permanent IPS LED backlighting fails to reproduce deep blacks.

OLED displays

OLED technology (organic light-emitting diode) is based on the manufacture of displays based on organic light-emitting diodes. The main technical difference between these products and their predecessors IPS is the lack of external backlighting. In a more modern solution, OLEDs are self-emitting. All that is needed for this is to supply them with food. Therefore, OLED matrices have a film structure located between two conductors.

  • Minimum thickness. Due to the fact that modern matrices do not have a layer of LED backlighting, they are thinner. Thanks to this, the developers managed to reduce the thickness of the gadgets in which such displays are installed.
  • Deep black color. Organic LEDs, which are responsible for black color, are completely turned off without emitting a glow. Thanks to this, the black color is obtained as deep and saturated as possible.
  • Low power consumption. OLED displays do not have LED backlighting that is constantly on. This reduces the overall power consumption of the matrix.
  • Maximum viewing angles. The user’s position in relation to the display plane does not affect the image quality.
  • High contrast. Due to the ability to obtain deep blacks, the contrast of the matrix has increased.

No display technology is perfect, so OLEDs also have several drawbacks:

  • High price. The technology itself for manufacturing OLED displays is quite expensive, so they are usually installed exclusively in high-tech gadgets. The final product has a rather high cost.
  • Burnout of organic light-emitting diodes. Since each LED of an OLED matrix independently emits light, it has its own limited resource. Every year, developers are trying to optimize the performance of such displays in order to increase their lifespan.
  • The predominance of blue. This is a minor but notable drawback of OLED displays. As a result of the constant glow, blue is perceived brighter than red and green. Developers are trying to remove this effect by introducing additional technologies.

Which screen is better than IPS, OLED or Super Amoled

Just a few years ago, smartphone users were content with TFT displays. They were made using a technology based on thin-film transistors and were quite satisfied with the image quality of consumers. But with the development of the electronics industry, developers managed to reach a completely new level.

Changes for the better began with the advent of IPS matrices, which had maximum viewing angles and a bright picture. Soon they began to be replaced by OLED, Amoled displays. But which one actually provides a high-quality image, and is not just another marketing gimmick? We will try to answer this question in this article.

Amoled and Super Amoled

There is a lot of controversy on the web over the differences between OLED and Super Amoled displays. What exactly is an Amoled screen? OLED technology offers two ways to control pixels: active and passive. So, the Amoled display is made on the basis of an active matrix, hence the name of this type of screen. Active Matrix Organic Light-Emitting Diode.

In fact, all modern OLED matrices have active control, so you can safely put an equal sign between them and Amoled displays. Super Amoled is a product of Samsung, which gave this name to the screens of its new smartphones. Initially, the developers explained the term by the fact that they managed to remove the air gap between the films of the OLED matrix. However, other Amoled displays also have this structure, so the Super prefix has a more marketing purpose.

Which display to choose

When choosing the optimal display, it is recommended to focus on the future and get a gadget with a modern OLED screen. This is a truly advanced technology that will eventually completely supplant the IPS predecessors. OLED arrays have better color rendering, support 4K and VR content, are energy efficient and thinner.

The only significant drawback of such products is their high cost. Perhaps the price is too high at the initial stage and with the development of technology, developers will be able to offer a more affordable solution. For users with a limited budget, it is possible to choose an IPS matrix with high resolution and good color reproduction. As a result, the image quality on it can be even better than on OLED displays of some budget smartphones.

Welcome to the dark side.

The technology is not new: OLED screens are made up of light-emitting organic diodes and have been used in smartphones, tablets and TVs for several years. Laptops were an exception, primarily due to the cost of such a screen.

Things are changing, and several manufacturers. Lenovo, Alienware and HP have announced OLED laptops for 2016. Our first test candidate was the Lenovo ThinkPad X1 Yoga laptop. The laptop comes with an IPS screen, which can be replaced with OLED (same resolution QQHD 2560 x 1440 pixels) for 330. We decided to find out if the replacement is justified and what the new configuration offers.

Comparison of OLED and IPS screens

Contrast and viewing angles

The latest generation IPS panels are capable of glowing at a level of one to several thousand of maximum brightness. With a brightness of 300 cd / m2, the panel will show black with a brightness of 0.3 cd / m2. OLED display manufacturers claim a contrast of 20,000: 1, which means a black brightness of 0.00015 cd / m2. too low to be noticed and confirmed by the eyes.

Having used an OLED screen for a while, we can say with certainty that it shows much richer colors than an IPS panel. In a dark room, the difference becomes enormous and impossible to miss. IPS screens show black as a low-saturation gray, while OLED screens show real black. When watching movies, especially Star Trek, Interstellar or Gravity, it feels like the movie looks much better on a 14-inch laptop screen than on a TV several times larger diagonally.

When evaluating viewing angles, another advantage of OLED technology becomes apparent. In general, IPS panels have good viewing angles and stable color rendition when viewed from the side, but brightness and contrast are certainly lost. The picture on OLED screens looks the same from any viewing angle. Viewed from a 45 degree OLED screen, the screen is twice as bright as an IPS screen.

Burnout and age

Static elements such as the taskbar are very common in the Windows operating system, and burn-in can occur. At the time of writing this article, we did not encounter this problem. It is hoped that the screen will be as bright and high quality after a few years of use.

Another potential problem for OLED screens is the pixel aging that occurs for each of the base colors (red, blue and green). Samsung and other manufacturers are trying to prevent this problem by resizing the subpixels. Usually the blue subpixels are the largest, as can be seen in a microscope photograph. What cannot be circumvented is the gradual decrease in screen brightness. OLED display loses about 30-50% brightness after 20,000 hours of operation. For our laptop, which was used for 8 hours a day, the screen life will be 7 years.

Energy consumption and efficiency

To determine the power consumption and efficiency of both screens, we took the difference between the total consumption of the laptop and its consumption with the screen off.

The IPS panel showed an almost linear correlation between power consumption and brightness. At 2 cd / m2, we determined the consumption at 1.5 W, at 150 cd / m2 the consumption was 3.9 W and at 240 cd / m2 about 5.2 W.

When testing the OLED display, we got a slightly higher minimum power consumption of 1.9W. With a minimum number of white points and an increase in brightness to 300 cd / m2, consumption remained practically unchanged. Fully white background at 198 cd / m2 yielded a whopping 8.7 watts.

When using the Internet or when working with text, about 50.70% of the screen remains white. This is important to consider, because in this mode, the OLED screen will consume much more than IPS and will greatly reduce the battery life of the laptop. When watching movies, OLED screen will be more efficient or not worse than IPS screen.


Before getting into details, let’s talk about OLED technology in general. While conventional LCD screens are actually filters that let the backlight pass through and adjust the intensity and color, OLED pixels are themselves light sources. This approach has several advantages:

  • Black areas of the screen do not light up
  • The darker the screen gets, the less power it uses
  • Viewing angles are flawless
  • Very wide color palette
  • Fast response time
  • Lack of backlight makes screens much thinner

This technology also has disadvantages, we found four of them:

  • Maximum brightness is limited
  • High production cost
  • Screen pixels may be burned out
  • These screens are not durable

In this article, we will try to find out how OLED screens in laptops are susceptible to these disadvantages.

Advantages and disadvantages of IPS displays

    IPS displays have been developed and improved for 2 decades, during this period the technology has managed to gain a number of advantages.

    So, the main advantages of IPS matrices are:

    • Availability. Over the long years of technology development, many companies have mastered it, making the mass production of IPS screens relatively cheap. So, the cost of a display with FullHD resolution now starts from about 10. The low cost of these screens made smartphones equipped with them more affordable for users.
    • Color rendering. If the IPS screen is well calibrated, then it will reproduce colors as accurately as possible. By the way, that is why IPS matrices are used in professional monitors for photographers, graphic artists, designers, etc. They have the greatest coverage of shades, due to which the colors on the screen are reproduced as realistically as possible.
    • Fixed energy consumption. The liquid crystals that form the image on the IPS screen practically do not consume current, the main consumer of which is the backlight diodes. In this regard, the power consumption does not in any way depend on the picture on the screen and is determined only by the backlight level. Fixed power consumption of IPS displays provides approximately equal device autonomy while watching movies, surfing the web, chatting on social networks, etc.
    • Durability. IPS also surpasses AMOLED in terms of reliability, because liquid crystals practically do not age and do not wear out. Only the backlight LEDs can degrade, the service life of which is also very long and amounts to tens of thousands of hours. That is why, even after five years, the display retains almost all of its original brightness.

    Despite the significant advantages, IPS also has disadvantages, and fundamental ones, which are extremely difficult to eliminate through the development of technology. Let’s take a look at each of them:

    • Insufficiently deep black color. The problem is that liquid crystals, which display black, block the light coming from the backlight not one hundred percent. Since the backlighting of the IPS display is common to the entire matrix, its brightness is not reduced and the panel remains constantly illuminated. As a consequence, this negatively affects the depth of black.
    • Low contrast. In general, the contrast level of such matrices is acceptable for comfortable image perception, but still, in this indicator, AMOLED displays are ahead of IPS screens. Due to the shallow blackness, the difference between the darkest and brightest pixels in IPS displays is less than that of competing LED arrays.
    • Significant response time. IPS matrices do not have a very high pixel response rate, somewhere within ten milliseconds. On the one hand, this is enough for a comfortable perception of the image when watching video, on the other hand, this is not enough, for example, for VR content, as well as for other resource-intensive tasks.

    Which is better AMOLED or IPS? All the pros and cons of smartphone screens.

    Greetings to all! As a rule, modern smartphone manufacturers install liquid crystal (IPS) or organic (AMOLED) displays in their devices. At the moment, both technologies have undergone a lot of significant changes, due to which the image quality has improved markedly. Nevertheless, the debate over which of these two matrices is better is still ongoing.

    Today, the competition between display types has boiled down to a rivalry between two worthy options. AMOLED and IPS. The rest of the matrices were replaced or completely ceased to be used in mobile devices.

    The most famous smartphones with IPS screens are Apple brand products, as well as budget and mid-budget models, such as:

    • iPhone XR
    • iPhone 11
    • iPhone 7/7 Plus, iPhone 8/8 Plus
    • Honor 20 Pro
    • Huawei P30 Lite
    • Xiaomi Redmi Note 7 and others.

    If we talk about OLED displays, then they are installed on almost all flagships, and are also found in mid-range phones. For example, these are such popular smartphones as:

    • Samsung Galaxy S and Note series
    • iPhone 11 Pro, iPhone XS, iPhone X
    • Xiaomi flagships
    • Huawei flagships
    • Sony Xperia 1 and Xperia XZ3
    • And many others

    Quite a lot has already been said about which screen is better than AMOLED or IPS. Both matrices are constantly improving, getting rid of shortcomings, their negative sides are becoming less and less significant. Now we will try to find out which screen is better, consider all the advantages and disadvantages of each technology.

    Pros and cons of AMOLED displays

      OLED technology involves the use of arrays of miniature LEDs that are located on a matrix. They are independent, therefore they have their advantages over IPS, but they also have disadvantages.

      The advantages of AMOLED displays are:

      • AMOLED technology is newer than IPS technology, so its creators were able to largely eliminate the disadvantages characteristic of liquid crystal screens.
      • Separate pixel glow. The peculiarity of AMOLED displays is that each pixel is an independent light source. The system manages each such element independently of the others. When black is displayed, the corresponding pixel is not lit, and when mixed shades are displayed, it is brighter. This is why AMOLED screens exhibit excellent contrast and maximum black depth.
      • Almost instant reaction. LED pixel response rates are significantly faster than IPS displays. These panels are capable of reproducing a dynamic image with a high level of frame rate. This makes the picture smoother. This feature improves gameplay in games and is useful for better interaction with VR.
      • Lower power consumption while showing dark tones. As I said before, each pixel on this matrix glows independently. And the lighter the color of a pixel, the brighter it is, and vice versa. Therefore, while displaying dark tones, AMOLED screens consume less power than IPS displays. But it should be borne in mind that displaying white, AMOLED panels will consume a similar, and sometimes even more battery power than IPS screens.
      • Small thickness. Given the fact that these panels do not have a layer that scatters light from the backlight into crystals, AMOLED displays are thinner. Thanks to this, the manufacturer can reduce the size of the smartphone, while maintaining the reliability of the device and without cutting back on the battery capacity. Also, there is potentially the possibility of creating not only curved, but also flexible AMOLED matrices, which is impossible for IPS.

      But AMOLEDs also have their drawbacks. Most of them are caused by blue LEDs. I note that they have a more complex production, and at the same time, lower quality than the red and green ones. So, the main disadvantages of AMOLED matrices are:

      • PWM or blue. When purchasing a smartphone with an AMOLED display, you have to choose between the blueness of light tones and pulse width control of the brightness level. This is due to the fact that blue subpixels will be perceived more strongly than green and red ones during continuous light. To correct this phenomenon, PWM control of the brightness level is used, but in this case another drawback appears. With the maximum brightness of the screen, PWM is absent or remains at the border of perception and practically does not affect the eyes. But when the backlight level is low, the PWM frequency also decreases. As a consequence, low flicker levels, which are around 60 Hz, can cause eye fatigue.
      • Blue burnout effect. The problem here also lies in the blue LEDs, which have a shorter lifespan than the green and red ones. In this regard, with prolonged use, there is a possibility of distortion of the natural color reproduction. In this case, the display will turn yellow, the overall color rendition will deteriorate, and warm tones will prevail in the white balance.
      • Memory effect. Since miniature LEDs are prone to fading, areas of the screen displaying bright, static images, such as a clock, may lose their original brightness over time. As a result, in such places, silhouettes of these elements can be seen, even if they are not currently displayed.
      • Another fundamental drawback of these panels is the PenTile structure, which, unfortunately, is still typical for many matrices. This structure assumes the presence of an unequal number of green, red and blue subpixels in the matrix. As a rule, PenTile technology is used to compensate for the imperfections of blue LEDs. Unfortunately, this solution has a side effect of reduced image clarity, which is especially noticeable when using VR headsets.

      So, if you analyze all the pros and cons, you can make an unambiguous conclusion that it is impossible to better, AMOLED or IPS. Each technology has its own advantages and disadvantages. At the same time, there is always a regularity. the more expensive a smartphone is, the less are the disadvantages of its display and, accordingly, its advantages are more noticeable.

      Considering the peculiarities of these matrices, we can say that IPS screens with high resolution are preferable if you are primarily interested in maximum image clarity, you spend a lot of time surfing the web, instant messengers and, in general, work more with light colors.

      On the other hand, AMOLED displays are gaining more and more popularity, and it is their leading companies that install them in the most expensive and prestigious smartphones. It is clear that AMOLED screens are the future, and although this technology is not yet ideal, you can already buy a flagship smartphone equipped with a high-quality LED display and enjoy its high brightness, contrast and deep blacks.

      Write in the comments which type of matrix do you think is more reliable and preferable today. a relatively new AMOLED or a proven IPS? Well that’s all for now!
