IPS screen - what is it and what are the advantages of technology

Modern electronic devices are almost universal. For example, the smartphone does an excellent job not only with calls (their reception and commission), but also the ability to surf the Internet, listen to music, watch videos or read books. For the same tasks, the tablet is suitable. The screen is one of the most important parts of electronics, especially if it is a touchscreen and serves not only for displaying files, but also for management. We will become acquainted with the characteristics of displays and the technologies by which they are created. We will pay special attention to what an IPS screen is, what kind of technology it is, what are its advantages.

How is the LCD screen

First of all, we'll figure out how the liquid crystal display is arranged, which is equipped with modern technology. First, it is an active matrix. It consists of micro-film transistors. Thanks to them, an image is formed. Secondly, it is a layer of liquid crystals. They are equipped with light filters and create R-, G-, B-subpixels. Thirdly, it is a screen backlighting system that allows you to make the image visible. It can be fluorescent or LED.

Features of IPS-technology

Strictly speaking, the IPS matrix is a kind of TFT technology, on which LCD screens are created. TFTs are often understood as monitors produced by the TN-TFT method. Based on this, we can compare them. To get acquainted with the intricacies of the choice of electronics, we'll figure out what IPS screen technology is , what this term stands for. The main thing that distinguishes these displays from TN-TFT is the location of liquid crystal pixels. In the second case, they are spirally located at an angle of ninety degrees horizontally between the two plates. In the first (which we are most interested in) the matrix consists of thin-film transistors. And the crystals are located along the plane of the screen parallel to each other. Without the arrival of voltage on them, they do not turn. In TFT, each transistor controls one point on the screen.

The difference between IPS and TN-TFT

Let us consider in more detail the type of IPS screen , what it is. Monitors created with this technology have a lot of advantages. First of all, this is an excellent color rendering. The whole range of shades is bright, realistic. Thanks to a wide viewing angle, the image does not fade, from which point you look at it. The monitors have a higher, sharper contrast due to the fact that the black color is transmitted just perfectly. It is possible to note the following disadvantages, which the IPS screen type has. What is it, first of all, a large consumption of energy, a significant drawback. In addition, devices equipped with such screens are expensive, since their production is very expensive. Accordingly, TN-TFT have diametrically opposite characteristics. They have a smaller viewing angle, when the view point changes, the image is distorted. In the sun, it is not very convenient to use them. The picture darkens, glare prevents. However, such displays have a fast response, they consume less energy and are affordable. Therefore, such monitors are installed in budget models of electronics. Thus, we can conclude, in which cases the IPS-screen is suitable, that it is an excellent thing for fans of movies, photos and videos. However, due to less responsiveness they are not recommended to fans of dynamic computer games.

Developments of leading companies

The very technology of IPS was created by the Japanese company Hitachi in conjunction with NEC. New in it was the location of liquid crystal crystals: not in a spiral (as in TN-TFT), but parallel to each other and along the screen. As a result, such a monitor transmits colors brighter and more saturated. The image is visible even in the open sun. The viewing angle of the IPS matrix is one hundred and seventy eight degrees. You can watch on the screen from any point: bottom, top, right, left. The picture remains clear. Popular tablets with an IPS screen are manufactured by Apple, they are created on the IPS Retina matrix. One inch uses an increased pixel density. As a result, the image on the display goes without grain, the colors are transmitted smoothly. According to the developers, the human eye does not notice the microparticles, if the pixels are more than 300 ppi. Now devices with IPS-displays are becoming more affordable, they are beginning to supply budget models of electronics. New varieties of matrices are being created. For example, MVA / PVA. They have a fast response, a wide viewing angle and remarkable color rendition.

Devices with multitouch screen

Recently, electronic devices with touch controls have become very popular. And it's not just smartphones. Issue laptops, tablets, which have a touch screen IPS, serving to manage files, images. Such devices are indispensable for working with video, photos. Depending on the diagonal of the display, compact and full-format devices are found. The multi-touch touch screen is capable of recognizing ten touches at the same time, that is, you can work with two hands at this monitor. Small mobile devices, such as smartphones or tablets with a diagonal of seven inches, recognize five touches. This is quite enough if your smartphone has a small IPS-screen. That it is very convenient, appreciated by many buyers of compact devices.

Customer Reviews

Focusing on the choice of high-quality electronics for video editing, photo processing, you need to purchase laptops with a monitor that perfectly conveys colors and has high clarity and contrast. These characteristics are consistent with the technology described above. Due to the large viewing angle, colors do not fade and do not lose brightness, from which point on the screen you can see. Accordingly, buyers of mobile electronics reviews of their acquisitions leave only positive, noting all the above pluses. It can be concluded that the IPS-screen is very advantageous in electronic devices, that this is the most optimal choice for surfing the Internet, millions of users of mobile computer equipment could make sure.
