Polarizer is one of the important materials of liquid crystal display. It is a composite material made of polyvinyl alcohol (PVA) stretched film and cellulose acetate film (TAC) through multiple lamination, stretching, coating and other processes. , can realize liquid crystal display high brightness, high contrast characteristics. Polarizers account for about 10% of the cost of TFT-LCD (Thin Film Transistor Liquid Crystal Display) panels.

with a resolution of 1200*1920, a MIPI interface vertical screen, a brightness of 1500 lumens, which is clearly visible under strong outdoor light, and a contrast ratio of 1200.

The LCD screen itself does not emit light, and a backlight needs to be added to the back of the glass for normal display. This involves how to test the surface brightness and backlight uniformity of the LCD screen. The brightness of the LCD screen surface and backlight brightness are measured through BM -7 equipment test, the test is more accurate when the display is powered normally and displays a solid color picture.

IPS is the abbreviation of In-Plane Switching in English. The English meaning is in-plane switching hard screen technology, commonly known as "hard screen". It is the most advanced LCD panel technology in the world. Like wearing glasses. Generally, more mainstream mobile phones will use IPS screens, which have excellent display effects, so it has become one of the major selling points of many mobile phones.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

TFT liquid crystal display screen is a display screen widely used in various electronic devices, with high resolution, high brightness, and high contrast. With the continuous development of technology, the application of wide color gamut technology is becoming increasingly widespread, which can greatly improve the display effect of display screens and make them present more realistic colors.
