Classification And Difference Of LCD Screen

- Dec 10, 2020-

The screen is an integral part of all display devices. In recent years, display technology has developed rapidly, and various new technologies have emerged in an endless stream. There are countless professional terms such as LCD, IPS, AMOLED, ASV, etc., even those who are familiar with display devices may not be able to understand all of them. A simple explanation, I hope it helps everyone!

First of all, the most important thing is that the current mainstream mobile phone screen materials can be attributed to two categories: TFT-LCD and OLED. The two screens are essentially different in principle. LCD relies on a backlight panel, while OLED is self-luminous.

The full name of LCD is Liquid Crystal. After years of development, this technology is now relatively mature. This is also the current mainstream screen display technology. Like TFT, IPS, and SLCD on the market, they all belong to LCD screens. TFT is the collective name of all LCD panels. It is an early LCD screen. The screen display effect is average, but the cost is low. At present, most low-end machines use this screen. The screen display effect is also related to the manufacturer's adjustment. Will be better.

The IPS screen is commonly known as the "Super TFT". From a literal understanding, everyone can understand that this screen is also an LCD screen, which is an upgraded version of TFT, but its essence is still a TFT screen. But compared with TFT screen, the advantage of IPS screen is that the display effect is transparent and bright, and the viewing angle is large. It is said that the maximum viewing angle can be close to 180°. The retina screen of Apple iPhone 4 leads the popularization of IPS screens. The display effect of this screen will also be related to the ability of manufacturers to optimize and adjust. After all, many manufacturers currently use IPS screens but it is difficult to reach the standard of iPhone.

SLCD is commonly known as "SuperLCD", which is at a relatively high level among LCD screens. This material has good display effects and good color reproduction. The display effect is at a relatively high level, the transparency is excellent, and the saturation is well controlled, which is highly recognized by many users.

The biggest difference between OLED screens and LCD screens is that OLED screens display images through pixel self-luminescence, and the display effect is better than LCD screens, and it is also the trend of future screen development. At present, AMOLED screens in OLED have become the mainstream, and Samsung has mastered the core technology, and it has become more and more accurate in color reproduction, and the color cast is not as serious as in earlier products.

Super AMOLED is currently a very widely used product in the mobile phone OLED display market. The Super AMOLED screen has high color saturation and beautiful display, but the screen needs to use high resolution to alleviate the graininess.

As an indispensable part of the display device, the display screen has been iteratively upgraded for many years. If subdivided, there are still many aspects, and the ultimate purpose of these technologies is to improve the display effect of the screen, and the display effect of the screen does not only depend on a certain factor. Even if you get a screen of the same material, the display effect of the products launched by each manufacturer will be different. In addition to the manufacturer's adjustment, the display effect will be different when different display technologies and display materials are added.
