Which screen is better tft or ips

TFT and IPS matrices: features, advantages and disadvantages

In order to fully answer this question, it is necessary to thoroughly understand the differences between the two matrices, highlight their features, advantages and disadvantages. Knowing all these subtleties, you can easily choose a device whose display will fully meet your requirements. Our article will help you with this.

The main advantage of TFT displays is the relatively low cost of production in comparison with modern counterparts. In addition, such matrices have excellent brightness and response time. Due to this, distortion when viewing dynamic scenes is invisible. TFT displays are most commonly used in budget TVs and monitors.

  • low color rendering. The technology is limited to 6 bits per channel;
  • the spiral arrangement of the crystals negatively affects the image contrast;
  • image quality decreases markedly when the viewing angle is changed;
  • high probability of the appearance of “broken” pixels;
  • relatively low power consumption.

The disadvantages of TFT matrices are most noticeable when working with black. It can be distorted to gray, or vice versa, be too contrasting.

  • viewing angles, at which the image quality does not decrease, increased to 178 degrees;
  • improved color rendering. The amount of data transmitted per channel is increased to 8 bits;
  • significantly improved contrast;
  • reduced energy consumption;
  • low probability of “broken” or burnt-out pixels.

The image on the IPS matrix looks more lively and saturated, but this does not mean that this technology is devoid of drawbacks. Compared to its predecessor, IPS has significantly reduced image brightness. Also, due to the change in the control electrodes, such an indicator as the response time of the matrix suffered. Last, but not least, is the relatively high price for devices that use IPS displays. As a rule, they are 10-20% more expensive than SIMilar ones with a TFT matrix.

If image quality is important to you and you are willing to pay a little extra, then a device with an IPS display is the best choice.

This article is an example of the complete incompetence of the author. Comparison of TFT and IPS. this is an elderberry in the garden, and in Kiev. an uncle. You can compare TN, IPS, LED, AMOLED. TFT is a method of electronic control of LCD cells (TN, IPS and their other derivatives) and LED displays. Roughly speaking, all modern LCD and LED displays are controlled using TFT technology.
Author, teach materiel, as they say.

Creative shit, author asshole.
IPS is a kind of TFT.

IPS is a refined TN matrix.
Both will merge VA matrices in literally everything.
The main problem of IPS is the viewing angles. they are not there, like TN matrices, at 30-40 degrees there is a sharp darkening and then just a gray screen, i.e. no viewing angles at all.
The second problem of IPS matrices is low contrast, i.e. there is essentially no black color, which makes the image look poor and whitish.
So VA, no options.
Oled is better in theory, but in practice it turned out to be a bottom, unable to show anything more than 256 colors and with strong blues-greens. Also, OLED is very tired of the eyes, as well as from the flickering of the backlight, only the sensations are different. Owners of Oled TV, monitors or even smartphones will understand me perfectly. Colors don’t please, eyes get tired.
Therefore VA. no options.
And no curved ones. who buys them? Only a blind person will not see geometric distortions, in which it is impossible either in text, or in a film, or in a photo, only to play games.

Varieties of TFT displays, their advantages and disadvantages

Names like TN, IPS and MVA are all TFT displays. It’s easy to get confused about these names. Let’s try to figure out how they differ, and what is better.

TN-TFT and IPS at a glance

TN-TFT is the technology behind the matrix of the liquid crystal display. Here the crystals, when no voltage is applied to their cells, “look” at each other at an angle of 90 degrees. They are arranged in a spiral, and when voltage is applied to them, they rotate in such a way as to form the desired color.

IPS. this technology differs in that here the crystals are located parallel to each other in a single screen plane (in the first case, spiral). This is all complicated. in practice, the difference between TN and IPS screens is that IPS displays black color perfectly, resulting in a clearer and more saturated picture.

As for TN-TFT, the color rendering quality of this matrix does not inspire confidence. Here, each pixel can have its own hue, hence the colors are distorted. IPS-matrices show the picture much better, and also handle colors more carefully. IPS also allow you to observe what is happening on the screen from a large angle. If you look at the TN-TFT screen from the same angle, the colors will be distorted so much that it will be difficult to make out the picture.

Super TFT (or IPS)

IPS TFT technology solves all TN screen problems. The main difference from TN panels is the direction of movement of the crystals. In IPS displays, they move parallel to the plane of the panel, rather than perpendicular to it. This change reduces the scattering of light in the matrix and allows you to get wider viewing angles (from 170 °), a large color spectrum (up to 1 billion), high contrast (1: 1000). Blacks will be deeper and more perfect.

However, IPS also has a drawback: the response time of such matrices is 10-20 ms, which is not enough for modern video games, although it is acceptable. AMOLED screens have even longer response times.

This is not to say which is better: IPS or TN TFT technology. Each of them has pros and cons, so you need to proceed from the purpose for which you are buying the device. IPS is widely used in high quality monitors targeting professional graphic artists.

This technology is the most advanced. it combines the advantages of the previous two options. MVA displays have a wide viewing angle, excellent color and contrast, deep blacks and at the same time optimal response time.

When comparing displays with TFT IPS technology and SVA (a kind of MVA), it will be difficult to choose the best option. Everyone has dignity. SVA has only a slight difference in structure. in such a display, the crystals are aligned vertically, not horizontally. This affects their ability to transmit or block light, which determines the display brightness and blacks. In SVA displays, these parameters are at their best, although this does not mean that IPS shows a bad picture. SVA has a smaller viewing angle compared to IPS.

Understanding the TFT display

TFT LCD is a kind of active matrix liquid crystal displays. Each pixel of such displays is controlled by 1-4 thin film transistors (in English. Thin Film Transistor, abbreviated. TFT), which help to easily turn on / off the LEDs, creating a clearer, higher quality image.

The TFT display has two glass substrates with a layer of liquid crystals inside. The front glass support contains a color filter. The back substrate contains thin transistors arranged in columns and rows. Behind everything is the backlight.

Interesting to know: Each pixel is a small capacitor with a layer of liquid crystal sandwiched between transparent conductive layers of indium tin oxide. When the display is turned on, molecules in the liquid crystal layer bend at a specific angle and let light through. This creates the pixel that we see. Depending on the bending angle of the liquid crystal molecules, this or that color appears. All pixels together form a picture.

A standard TFT monitor has 1.3 million pixels, each of which controls a different transistor. They consist of thin films of amorphous silicon deposited on glass using PECVD technology (this method is usually used to create microprocessors). Each element works due to a small charge, so the image is redrawn very quickly, the picture is updated many times per second.

TN advantages

However, TN-TFT matrices have their own advantages. The main one is the lower pixel response rate. IPS takes longer to rotate the entire array of parallel crystals to the desired angle. Therefore, if we are talking about choosing a monitor for games or for displaying dynamic scenes, when rendering speed is very important, then it is best to choose screens based on TN-TFT technology.

On the other hand, during normal PC operation, the difference in pixel response time cannot be noticed. It is only visible when watching dynamic scenes, which is often the case in action films and video games.

Another plus is low power consumption. IPS-matrices are power-consuming, because they need a lot of stress to rotate the array of crystals. Consequently, TFT screens are better suited for mobile gadgets, where the issue of saving battery power is acute.

And yet. TN-TFT matrices are cheap. You cannot find a monitor today (apart from a used or CRT model) that would be cheaper than a model based on TN technology. Any budget electronics device with a screen will definitely use a TN-TFT matrix.

So, which screen is better: TFT or IPS:

That, in principle, is the whole difference between these matrices. Considering all the advantages and disadvantages, then, of course, it is easy to come to a concrete conclusion: IPS screens are much better.

Please rate the article:

When choosing a monitor, TV or telephone, the buyer often faces the choice of the type of screen. Which one should you give preference to: IPS or TFT? The reason for this confusion is the constant improvement of display technology.

All monitors with TFT technology can be divided into three main types:

  • IPS.
  • TNFilm.
  • PVA / MVA.

That is, TFT technology is an active matrix liquid crystal display, and IPS is one of the varieties of this matrix. And comparison of these two categories is not possible, since in practice they are one and the same. But if you still understand in more detail what a display with a TFT matrix is, then a comparison can be made, but not between screens, but between their manufacturing technologies: IPS and TFT-TN.

Important features

If we talk about which is better in operation: IPS or TFT, then it is worth noting that the former are more power-consuming. This is because it takes a lot of energy to rotate the crystals. That is why, if the manufacturer is faced with the task of making his device energy efficient, it usually uses a TN-TFT matrix.

If you choose a TFT or IPS screen, then it is worth noting the wider viewing angles of the second, namely 178 degrees in both planes, which is very convenient for the user. Other types of matrices have proven unable to provide this. And one more significant difference between these two technologies is the cost of products based on them. TFT matrices are currently the cheapest solution that is used in most budget models, and IPS belongs to a higher level, but it is not top-end either.

Terminology

To determine what will be better or worse in each case, it is required to find out what functions and tasks each type of matrix is ​​responsible for. In fact, IPS is a TFT, or rather its kind, in the manufacture of which a certain technology was used. TN-TFT. These technologies should be considered in more detail.

IPS or TFT display to choose?

The first technology allows you to get the highest quality, sharpest image, but it takes more time to rotate the crystals used. This affects the response time and other parameters, in particular the rate of battery discharge. The color rendering level of TN-matrices is much lower, but their response time is minimal. The crystals are arranged in a spiral here.

In fact, one can easily note an incredible chasm in the quality of screens powered by these two technologies. This also applies to cost. TN technology remains on the market solely because of the price, but it is not able to provide a juicy and bright picture.

IPS is a very successful continuation of the development of TFT displays. High contrast levels and fairly wide viewing angles are additional advantages of this technology. For example, with TN monitors, sometimes the black color itself changes its shade. However, the high energy consumption of IPS-based devices is forcing many manufacturers to resort to using alternative technologies or to lower this figure. Most often, matrices of this type are found in wired monitors that do not operate on a battery, which allows the device not to be so volatile. However, there are ongoing developments in this area.

Abbreviations are commonly used to denote characteristics or specificities. In this case, there is a terrible confusion regarding the comparison of IPS and TFT screens, because the IPS technology (matrix) is a kind of TFT matrix and nothing more. It is impossible to compare these 2 technologies with each other.

BUT! There is TN-TFT technology. you can make a choice and compare between it and IPS. Therefore, when we talk about which screen is better: IPS or TFT, we mean TFT screens in any case, but made on the basis of different technologies: TN and IPS.

Twited Nematic (TN) Film

This is an easier, cheaper and faster option. The response time of the matrix TFT TN screens is only 2-4 ms. They can display more frames per second, which is especially important when watching videos and playing video games.

However, TN devices have many disadvantages in terms of image quality:

  • The viewing angle of the TN display is only 50-90 °. This means that you can get the full effect of the graphics on the TFT TN screen only by looking at it directly. When viewed from the side, top or bottom, the picture will change its color;
  • low contrast ratios (maximum 500: 1) and a small range of colors. Such a device will not render all colors;
  • black color in TN screens is too bright, it lacks depth, and white is not bright enough, which is why nothing will be visible in sunlight.

Whether you are using the device for regular web browsing, office work or other daily tasks, then the TFT TN display will meet your needs. It is also suitable for gamers, since the image transfer rate is still more important during the game. But for business or graphics work that requires the highest levels of color and graphic fidelity, an IPS display is the best choice.

3.2. TN matrix response

This type of matrix has the fastest response, which makes such monitors the most suitable for fans of games and 3D films with vivid special effects.

If we talk about which IPS or TN matrix is ​​better in response, then TN has the advantage. However, it’s worth noting that at home, all of these benefits are minor. The choice depends solely on personal preference.

Which is better IPS or TN matrix

For a number of reasons, liquid crystal screens are in great demand among users and are the most in demand in the domestic market. Modern LCDs are classified into two types of matrixes. IPS and TN. In this regard, many buyers have a question, which is better than an IPS or TN screen?

Key features

In addition to the price, which is higher for IPS displays, it is necessary to list the main technical characteristics of the devices.

Image quality: color rendering, contrast, saturation. All these parameters are better in IPS due to the fact that the crystals are in the extreme position. This means that if you look at such a surface in contrasting light, you can see the picture. Their black color is “more black”.

For TN, it always remains gray due to the fact that the backlight of LCD monitors is always on.

Response speed or response time. Unfortunately, IPS technology, even in its best implementations, reaches a value of only 5ms. For TN, this indicator has long crossed the 2 ms border. For fans of computer games, this indicator is very critical.

If the device is going to be used to work in non-gaming applications (for example, a tablet for web surfing), then IPS will do. In addition, the power consumption of IPS matrices is higher.

Viewing angle. This parameter is better for IPS devices. If for TN it can be equal to 90 °, then with IPS, almost the entire field of view. 178 °. will display the picture without distortion and loss of color.

There are varieties of TNfilm matrices in which a film is additionally installed to help reduce such distortion, but such a monitor is more expensive.

IPS or TFT? IPS or TFT display is better?

Modern devices are equipped with screens of various configurations. The main ones at the moment are displays based on liquid crystals, but different technologies can be used for them, in particular, we are talking about TFT and IPS, which differ in a number of parameters, although they are descendants of the same invention.

Now there are a huge number of terms that denote certain technologies hidden under abbreviations. For example, many may have heard or read about IPS or TFT, but few understand what the real difference between them is. This is due to the lack of information in the electronics catalogs. That is why it is worth understanding these concepts, as well as deciding whether TFT or IPS. what’s better?

How it works

Structurally, the matrices consist of several layers, which, in addition to a thin layer with liquid crystals, also include polarizing filters and electrodes. The latter control the LCD layer, which determines how much light the matrix itself will transmit. It is tinted in a certain color already with a light filter, which is located on the outside of the monitor.

The SIMplest and cheapest matrix. TN. transmits light in the absence of voltage on the electrodes. When it is served, the layer is closed. In this case, the electrodes are located both before and after this layer. This determines the switching speed: it is higher.

In IPS, the electrodes are located only on the side of the inner substrate, and more time is spent on switching. In addition, the crystal molecules in TN have a twisted nematic position. a twisted crystal, and partially still transmit light always.

In IPS, crystal molecules occupy one of two mutually perpendicular positions. The light either passes or it doesn’t. And the term IPS itself is literally translated as “in plane switching”.

2.1. Color rendering of IPS matrix

Features of this technology made it possible to make the screen with the most realistic colors. It is worth noting that IPS displays are in greatest demand among professional photo editors, as well as among those who are engaged in image processing. This is due to the fact that IPS monitors have the greatest color depth (black and white), as well as the largest number of displayed colors and tints. about 1.07 billion.This makes the image as realistic as possible.

In addition, IPS screens have the highest brightness and contrast, which also has a positive effect on image quality.

What is the difference between an IPS screen and Super Amoled?

This is not possible for IPS. Separate pixel glow. In AMOLED screens, each pixel is itself a light source and is controlled by the system independently of the others. It does not glow when displayed in black, and when displayed with mixed shades, it may produce increased brightness.

What are the screens on smartphones?

LCD, TFT, IPS, AMOLED, P-OLED, QLED. this is a partial list of display technologies that can be found in the mass market of consumer electronics today.

Which type of screen is best for the eyes?

In principle, the conclusion is SIMple: IPS-displays are more convenient and comfortable for the eyes, but they are much more expensive than TN. PWM can be a problem. Many laptops use pulse width modulation (PWM) to control the brightness of the display backlight.

Which is better TFT or LCD display?

LCD is a type of display matrix based on liquid crystals. TFT is a type of active LCD-matrix. TFT-matrices are economical, provide high-quality picture, but power-consuming.

Which smartphone screen is better for the eyes?

A small screen with a high resolution is much safer on the eyes than a large one with a low one. On a small screen with a high resolution, the PPI will be higher as the pixels are closer together and the picture will be sharper.

What are the disadvantages of a TFT screen?

Disadvantages of TFT displays:

  • low color rendering.
  • the spiral arrangement of the crystals negatively affects the image contrast;
  • image quality decreases markedly when the viewing angle is changed;
  • high probability of the appearance of “broken” pixels;
  • relatively low power consumption.

What is the main difference between an IPS screen and a TN TFT screen?

TN-TFT and IPS at a glance

TN-TFT is the technology behind the matrix of the liquid crystal display. in practice, the difference between TN and IPS screens is that IPS displays blacks perfectly, resulting in a sharper and richer picture.

Which screen is better than ips or tft? What is TFT Screen Type?

A liquid crystal display with an active matrix (TFT LCD, English thin-film transistor. thin-film transistor). a type of liquid crystal display, which uses an active matrix controlled by thin-film transistors.

Which is better: TFT or IPS screen?

The IPS system reproduces and transmits images of high quality, but the actual rotation of the internal elements when voltage is applied takes a longer period of time. This increases the response time and other parameters that increase power consumption and reduce battery life. In TN devices, the transmission quality is much worse, but the operation time is minimal (due to the arrangement of the crystals in the form of a spiral).

In general, I would like to note that there is a huge gap between the two technologies, in which there are many innovations. First of all, this abyss lies in the price. The TN matrix can still be purchased on the market, but it is there only because of the low price. You can forget about the quality on the screen.

Devices based on IPS, for the most part, operate in widescreen mode. This allows you to reproduce the original colors without distorting them. In the standard scheme, the user will not lose quality when the monitor is rotated 178 degrees (it does not matter whether it is vertical or horizontal).

TFT-TN

It is the oldest type of matrix, but still occupies a significant part of the market, without giving up its own positions. Specifically, TN products have not been available for a long time, so only modified versions remained. The update of the scheme allows increasing the viewing angles along the horizon up to 150 degrees, however, the vertical angles cannot boast of such numbers. Along the vertical, deviations of even ten degrees begin to change colors, in some cases they are even inverted. Most surfaces cover a maximum of 30% sRGB, which is not enough for color grading.

Another disadvantage is the low brightness, which rarely exceeds 150 cd / m2, which is not enough for indoor use.

At first glance, it seems that the old schemes are no longer needed on the market, but this is not the case. Due to their fast response and minimal response time, they have found their place in premium gaming devices. Rarely does the delay exceed one ms, which outputs nearly 1000 frames per second.

Unfortunately, modern monitors of this type will cost the buyer almost 500.

We started our journey with mobile phones, where large viewing angles were not required (like TFT), and the minimum values ​​were enough. Over the past 3 years, the cost has dropped several times, and now it is found even in the cheapest computers.

There are two advantages to a parallel circuit:

  • Widescreen viewing. The viewing angle is almost 180 degrees, and the indicators for horizontal and vertical are the same.
  • Coverage of the color palette. Even budget models cover nearly 100% sRGB.

Of course, there are also disadvantages:

  • Contrast. The indicator does not exceed 1000 to 1, which slightly affects some colors. For example, black is not very SIMilar to black (glow effect).
  • Response time. The internal elements react to one operation in about 45 ms, which makes it possible to produce a maximum of 30 frames per second. Now the situation has changed a bit, the system of work “responds” no more than 6 ms, which raises the indicator to 150 frames per second. This is enough to run resource-intensive games.

Thus, the main difference between IPS and TFT-IPS is in response time and viewing degrees.

which, screen, better

Screen type IPS or TFT. which is better

The smartphone has ceased to be a common means of communication, replacing many accessories. A person perceives all information visually, so the developers are trying to improve the image quality on monitors / smartphones every time. Despite the many presentations and information, many users do not know which screen is better than TFT or IPS.

What does TFT and IPS screen matrix type mean?

TN-TFT. creation of transistors with thin films that form the surface. In this arrangement, without applying pressure, the internal elements rotate towards each other at right angles between the two plates in the horizontal plane. The placement form is a spiral, which is why when voltage is applied through them, black pixels are formed. Pixels remain white without voltage.

IPS. the creation of a liquid crystal surface using thin-film transistors. The principle of placing elements inside is parallel, along one plane. This is where the main difference lies. in TFT, the crystals are arranged spirally. Without applying voltage, they do not acquire color, because a turn will not occur.

Pros and cons of the IPS matrix

  • Ability to work in widescreen mode.
  • Low energy consumption.
  • High-quality rendering and high brightness.
  • High resolution capability that dramatically increases the PPI.
  • Effective sun protection.
  • Price
  • Viewing angles cannot be called maximum, therefore, with a strong tilt, the image deforms colors.

Most smartphones are equipped with IPS displays. TN models are used in the corporate sector. Firms looking to keep costs down are using these phones for their own employees. For themselves, hardly anyone will buy such a phone.

Work speed

TFT works much faster than the modified continuation. It takes a long time for the elements in the IPL to turn the entire array of crystals into the desired position. Therefore, for tasks in which you need to quickly draw an object, it is more important to use “outdated” TFTs, but when solving standard tasks, the user will not notice the difference in the time spent on the response.

Monitors and displays with IPS technology with higher power consumption. The boost is due to the high voltage that is applied to the crystals for rotation. Therefore, for economical use in a mobile phone, it is better to choose TFT technology.

The difference between IPS and TFT

Screens with two placement systems also differ in the resulting picture. In a parallel crystal arrangement, an image with an increased level of contrast, which is achieved by perfect black reproduction. Parallel arrangement clearly conveys shades.

The transmission of TFT shades is much weaker. With this scheme of work, each pixel changes the color tone. Due to low color rendering, there is a risk of distortion of the final image.

As a result

Answering the question, how does one technology differ from another, one should not forget about the cost and purpose. The TN matrix is ​​the initial one, which pleases owners with a fast playback speed, but it will cost 500 or more. modern matrices began as budget versions for smartphones, but a number of modifications managed to tighten certain parameters and raise the IPS to the modern level.

Which is better IPS or TFT

Technology does not stand still, and LCD production is no exception. However, due to the constant development and release of new technologies in the manufacture of screens, as well as due to special marketing approaches to advertising, many buyers when choosing a monitor or TV may have the question of what is better than an IPS or TFT screen?

0.1. TFT IPS matrix

To answer this question, you need to understand what IPS technology is and what a TFT screen is. Only by knowing this, you will be able to understand what is the difference between these technologies. This, in turn, will help you make the right choice of a screen that will fully meet your requirements.

So what is a TFT display

As you may have guessed, TFT is the abbreviated name for the technology. Completely it looks like this. Thin Film Transistor, which means thin film transistor in Russian. Basically, a TFT display is a type of liquid crystal display that is based on an active matrix. In other words, it is a conventional active matrix liquid crystal display. That is, the control of liquid crystal molecules occurs using special thin-film transistors.

What is IPS technology

IPS is also short for In-Plane Switching. It is a kind of active matrix LCD. This means that the question of which is better than TFT or IPS is erroneous, since they are essentially the same thing. precisely, IPS is a type of FTF display matrix.

The IPS technology got its name due to the unique arrangement of electrodes, which are located on the same plane with liquid crystal molecules. In turn, liquid crystals are located parallel to the plane of the screen. This solution made it possible to significantly increase the viewing angles, as well as to increase the brightness and contrast of the image.

Today, there are three most common types of active matrix TFT displays:

  • TNFilm;
  • IPS;
  • PVA / MVA.

Thus, it becomes obvious that the difference between TFT and IPS lies only in the fact that TFT is a type of LCD screen with an active matrix, and IPS is the same active matrix in a TFT display, or rather one of the types of matrices. It should be noted that such a matrix is ​​the most common among users all over the world.

How TFT and IPS displays differ

The common misconception that there is a difference between TFT and IPS has arisen from the marketing gimmicks of sales managers. In an effort to attract new customers, marketers do not disseminate full information about the technology, which creates the illusion that a completely new development is entering the world. Of course, IPS is a newer development than TN, but you cannot choose which TFT or IPS display is better for the above reasons.

3.1. Advantages of IPS technology

You already know that there is no difference between TFT and IPS, however, a completely logical question arises, TNFilm and TFT IPS, what is the difference? To answer this question, it is worth considering the advantages of IPS matrices, which are as follows:

  • Increased viewing angles;
  • Increased brightness and contrast;
  • Significantly improved color reproduction and superiority in the number of displayed colors and tints.

These are the three main advantages of IPS displays that allow them to compete with plasma panels. No wonder more and more manufacturers prefer IPS matrices. In addition, such displays have great prospects.
