IPS-display: what is it?

is Now most smartphone is equipped with IPS-screen. What are the advantages of this matrix?

For a long time, computer monitors and mobile phones equipped with TFT-display. It seemed that the possibilities of this matrix is enough to view high-quality pictures. But gradually it became clear that there are other technologies that greatly increase the viewing angles and enhance color reproduction. One of these technologies is the IPS mentioned in this article.

Building IPS-screen

At the time the invention IPS-displays allowed the creators of smartphones and tablets to make a big leap in the quality of the picture displayed. For the first time a mobile device came close to this parameter to plasma TVs! Smartphones now could boast almost the maximum viewing angles, and color reproduction is started pleasantly pleasing to the eye.

arrangements of subpixels

Made by technology IPS matrix consists of parallel thin-film transistors. Or liquid crystals as they are called more often. Another difference from the TFT-display is the fact that the crystals in the absence of stress (when you need to achieve display of black color) do not rotate. These two properties lead to the fact that the colors are almost not distorted, no matter what the viewing angle is not chosen by the spectator. Noticeable as well that the IPS screen gives deeper blacks, especially the expensive variation embedded in flagship smartphones or expensive televisions.

The structure of each sub-pixel

Disadvantages of IPS-matrix

Parallel arrangement of the pixels also plays a negative role. Unfortunately, the IPS screen has a a long response time. If the developers did not use expensive tricks, this parameter will be equal to about 5-8 msec. At TFT-matrix this parameter usually does not exceed 2-3 MS. Of course, in ordinary life, a difference people hardly notice. Felt decent response time in some games. The speech in this case goes about the games for PS4 and Xbox One, on the smartphone such problems is not felt.

Another disadvantage of the technology lies in the high power consumption. Anyway, and smartphones with IPS display consume power quickly enough. This is due to the fact that to rotate the array located parallel to each other crystals (this is necessary for display of a particular color) is much harder — it requires more voltage. That's why phones with IPS screen are usually equipped with either long battery life or energy-efficient processor.

The behavior of the sub-pixels at different brightness

But the price is clearly recorded in the disadvantages not. Of course, the TFT-matrix is still cheaper than what those still embedded in the push-button phones. But the difference is not so big, so even extra low-cost Android-based smartphones are getting more IPS display. But you need to understand that not all screens are created by this technology are the same. The cheapest still have some color distortion when viewing from certain angles. But even such matrices give a much better picture than a TFT of the product.

What screen type is better: IPS or AMOLED?

of Course, this begs now and compare with much more expensive screens made AMOLED technology. Such matrices are based on organic light-emitting diodes. That is, their pixels are not only situated parallel to each other, thereby achieving the maximum viewing angle, they glow on their own! In this regard, based on organic light emitting diode display provides deeper black colors, and the realism of the images increases significantly.

so, AMOLED vs IPS. Who wins? Of course, more expensive matrix. Not without reason in the most advanced TVs embedded OLED screens. The difference between the two types of displays to notice very easily, especially when you compare matrix built into relatively inexpensive smartphones. However, we must not forget that the production of compact AMOLED displays in normal amounts, adjusted only Samsung. Of course, the South Koreans sell some of their products on the side, but still AMOLED displays found in other smartphones infrequently. In this regard, to select buyers do not have — if the amount of the purchase of the device selected is not particularly big, it will have to find a device with IPS screen.

Summarizing

The IPS will not be forgotten for a very long time. Now made it the screens have the best ratio of price and quality. In no case do not buy a smartphone equipped with a TFT display — but this technology has run its course. Well, think about the AMOLED screen is necessary only if a large enough free amount.
