Mobile phone screen material difference

Mobile phone screen material difference

Of all the parts of a smartphone, the screen is probably the one we come into contact with the most. Sometimes the quality of the screen is the main condition that determines whether we buy or not, so many of our friends will take the screen size as the first choice when buying a mobile phone. However, only caring about the size or resolution of the mobile phone screen, but not caring about the quality of the screen material, this is a big purchase misunderstanding. You must know that the quality of the screen of a mobile phone is related to many factors, such as screen material and lamination technology.

So, which is the best material for the mobile phone screen? The following will bring you a list of pure dry goods knowledge points of screen materials!

1. LCD Display

The full name of LCD (Liquid Crystal Display) is liquid crystal display, which is the most used mobile phone screen material, characterized by cheap price, widely used, and needs to be supported by backlight when displaying.

The LCD display is composed of a backlight, a lower polarizer, a driver layer, a liquid crystal layer, a color filter, and an upper polarizer. The driver layer is composed of thin-film transistors (TFT), so it is common to see TFT-LCD.

Super LCD is the favorite mobile phone screen material of most mobile phone manufacturers, and most of the current high-end mobile phones are made of super LCD screen material, although it is not as bright as super AMOLED, it is indeed closer to the real color, and it is also the screen that consumers like at present. The advantage of this mobile phone screen material is that the comprehensive quality is relatively strong and cost-effective, and the disadvantage is that it is slightly thicker than other screens and consumes more power.

2. TFT screen

TFT (Thin Film Transistor) is a type of active matrix liquid crystal display.

TFT LCD display is characterized by good brightness, high contrast, strong sense of hierarchy and bright colors, but it also has the shortcomings of high power consumption and high cost.

TFT LCD screen adopts a combination of "back transmission" and "reflection", a special light pipe is set on the back of the liquid crystal, and the liquid crystal is equipped with a semiconductor switch for each pixel, and its processing technology is similar to that of large-scale integrated circuits. This design not only improves the response speed of the display screen, but also can accurately control the display grayscale, so the color of TFT LCD is more realistic, the display effect is the best, the contrast is the strongest, the visual effect is the most gorgeous, and the power consumption is the largest. The characteristics of high contrast, high response, wide viewing angle and large-capacity display make TFT almost the most perfect LCD product at present, so high-end mobile phones generally use TFT screen.

3. in-cell

In-cell refers to the method of embedding touch panel functions into liquid crystal pixels. The integration of touch panel and LCD panel includes an "in-cell" method and an "on-cell" method. On-cell, on the other hand, refers to the method of embedding the touch panel function between the color filter substrate and the polarizer.

4. IPS screen

IPS, commonly known as "Super TFT", is a technology upgraded from TFT, and the essence is still a TFT screen, but a TFT screen using IPS technology. Compared with ordinary TFT screens, it has the advantages of large viewing angles, accurate color reproduction, no water ripples in touch, environmental protection and power saving.

Representative models are iPhone,All along,iPhone is using IPS screen,The best quality IPS screen every year was basically bought by Apple,Compared with Android phones at the same price,iPhone because of the use of IPS screen,Even if the resolution is lower,The look and feel of the screen can still be maintained to the top level。 But starting with the iPhone X, Apple phones have started to use AMOLED screens.

5. SLCD screen

SLCD is the abbreviation of Splice Liquid Crystal Display, that is, splicing special LCD screen. SLCD is a high-grade derivative of LCD. SLCD is a complete video wall, which can be used as a display alone or spliced into a large screen. According to different needs, it realizes single-screen split display, single-screen separate display, arbitrary combination display, full-screen splicing, vertical screen display, optional compensation or covering of image frames, and real-time processing of full-HD signals. SLCD can meet the needs of different use occasions and different signal inputs, with a service life of more than 50,000 hours, without any burns and damage, and low maintenance costs; Any several units can be combined to display a complete picture, any picture can be superimposed on other screens, through the software, any signal can be moved on the splicing curtain wall with a screen as a unit; Also, in terms of viewing angles on the screen, it's pretty good. HTC's new HTC phone, HTCIncredibleS, which has been hot on the market recently, uses an SLCD display.

6. OLED

OLED (Organic Light-Emitting Diode) refers to organic light-emitting diode, OLED does not need backlight support, has self-illumination, and has the advantages of wide viewing angle, high contrast, low power consumption, high reaction rate, full color, and simple manufacturing process.

OLED (Organic Light Emitting Display) is an organic light-emitting display, which is a new type of product in the material of the mobile phone screen, and is known as the "dream display". Unlike traditional LCD displays, OLED display technology does not require a backlight and uses a very thin coating of organic materials and a glass substrate that emits light when an electric current passes through it. The most important thing is that OLED screens can be made lighter and thinner, with larger viewing angles, and can significantly save power, which is important for the development of smartphones. Samsung's SUPER AMOLED and SUPER AMOLED Plus are both improved versions of this mobile phone screen material. The advantages of this mobile phone screen material are high contrast, power saving, and high color saturation.

7. AMOLED screen

In the field of AMOLED display, Samsung and LG can be said to dominate the world, with a market share of more than 90%, so the best AMOLED screen mobile phone, of course, is Samsung's latest flagship phone, such as Samsung Note9, S9, Xiaomi 8, OPPO Find X, vivo nex, Meizu 16, Apple iPhone X, etc.

AMOLED is an active matrix organic light-emitting diode panel. Compared with traditional LCD panels, AMOLED has the advantages of fast response, self-illumination, excellent display effect and lower power consumption, as well as faster response, higher contrast and wider viewing angle. AMOLED uses active luminescence technology, in layman's terms, every pixel on the screen actually has the characteristics of self-luminescence in addition to completing the function of displaying colors, so that not all the pixels on the screen are emitting light in any kind of background, and the pixels in the pure black place not only fail to display but also do not emit light, which saves power to a great extent. At the same time, it is also a good protection for the screen of the phone.
