Modern electronic devices are almost universal. So, for example, a smartphone does an excellent job not only with calls (receiving and making them), but also with the ability to surf the Internet, listen to music, watch videos or read books. For the same tasks, a tablet is suitable. The screen is one of the most important parts of electronics, especially if it is touch-sensitive and serves not only to display files, but also to control. Let's get acquainted with the characteristics of displays and the technologies by which they are created. Let's pay special attention to what an IPS screen is, what kind of technology it is, what are its advantages.
How the LCD screen works
First of all, let's figure out how the liquid crystal display is arranged, which is equipped with modern technology. First, it is an active matrix. It consists of microfilm transistors. Thanks to them, the image is formed. Secondly, it is a layer of liquid crystals. They are equipped with light filters and create R-, G-, B-subpixels. Thirdly, this is a screen backlight system that allows you to make the image visible. It can be fluorescent or LED.
IPS Features-technology
Strictly speaking, the IPS matrix is a kind of TFT technology, which is used to create LCD screens. TFT is often understood as monitors produced by the TN-TFT process. Based on this, they can be compared. To get acquainted with the intricacies of choosing electronics, let's figure out what IPS screen technology is, what this concept means. The main thing that distinguishes these displays from TN-TFT is the arrangement of liquid crystal pixels. In the second case, they are arranged in a spiral, located at an angle of ninety degrees horizontally between two plates. In the first one (which interests us the most), the matrix consists of thin-film transistors. Moreover, the crystals are located along the plane of the screen parallel to each other. Without voltage applied to them, they do not turn. With TFT, each transistor controls one point of the screen.
The difference between IPS and TN-TFT
Let's take a closer look at the type of IPS screen, what it is. Monitors created using this technology have a lot of advantages. First of all, it's a great color rendering. The whole range of shades is bright, realistic. Thanks to the wide viewing angle, the image does not fade, no matter where you look at it. Monitors have a higher, crisper contrast ratio due to the fact that blacks are rendered just perfectly. The following disadvantages that the IPS screen type has can be noted. What is it, first of all, a large energy consumption, a significant disadvantage. In addition, devices equipped with such screens are expensive, since their production is very expensive. Accordingly, TN-TFTs have diametrically opposed characteristics. They have a smaller viewing angle; when you change the point of view, the image is distorted. In the sun, they are not very convenient to use. The picture darkens, glare interferes. However, these displays are fast responsive, consume less power, 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 this is a great thing for movie, photo and video lovers. However, due to their lesser responsiveness, they are not recommended for fans of fast-paced PC games.
Developed by leading companies
IPS technology itself was created by the Japanese company Hitachi together with NEC. New in it was the arrangement of liquid crystals: not in a spiral (as in TN-TFT), but parallel to each other and along the screen. As a result, such a monitor renders colors more vivid and 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 look at the screen from any point: from below, from above, to the right, to the left. The picture remains clear. Popular tablets with an IPS screen are produced by Apple, they are created on an IPS Retina matrix. One inch uses an increased pixel density. As a result, the image on the display comes out without graininess, colors are transmitted smoothly. According to the developers, the human eye does not notice microparticles if the pixels are more than 300 ppi. Now devices with IPS displays are becoming more affordableprice, they begin to supply budget models of electronics. New varieties of matrices are being created. For example, MVA/PVA. They feature fast response, wide viewing angle and excellent color reproduction.
Devices with multi-touch screen
Recently, electronic devices with touch controls have gained great popularity. And it's not just smartphones. They produce laptops, tablets, which have an IPS touch screen that serves to manage files and images. Such devices are indispensable for working with video, photos. Depending on the diagonal of the display, there are compact and full-size devices. The multi-touch touch screen is capable of recognizing ten touches at the same time, that is, you can work on such a monitor with two hands at once. Small mobile devices such as seven-inch smartphones or tablets recognize five touches. This is quite enough if your smartphone has a small IPS screen. That it is very convenient was appreciated by many buyers of compact devices.
Customer Reviews
From the choice of high quality electronics for video editing, photo processing, you need to buy laptops with a monitor that is excellent in color reproduction and has high definition and contrast. These characteristics are fully consistent with the technology described above. Due to the large viewing angle, the colors do not fade and do not lose their brightness, from which point you look at the screen. Accordingly, buyers of mobile electronicsfeedback on their purchases leave only positive, noting all the above pluses. It can be concluded that an IPS screen is very beneficial in electronic devices, that this is the best choice for surfing the Internet, millions of users of mobile computer equipment have been able to make sure.
