Industrial and Medical Display
There are many kinds of LCD classification standards, which can be divided into passive matrix and active matrix according to the driving mode
Passive matrix: Passive matrix LCD can be divided into TN-LCD(TwistedNematic LCD), STN-LCD(SuperTN-LCD) and DSTN-LCD(Doublelayer STN-LCD).
Active matrix: Active matrix LCD, also known as TFT-LCD, is widely used at present. Tft-lcd is short for thin-filmliquid-Crystal Display
The TFT-thin Film Transistor
Liquid Crystal Display
Short for TFT-LCD Liquid-CrystalDisplay
Tft-lcd has been widely used in various display equipment due to its advantages of small size, light weight, low radiation, low power consumption and full color.
Functions of TFT-LCD structure
(1) Backlight plate module: provide the source of light;
(2) Upper and lower polarizing plates, TFT Glass Substrate, liquid crystal: forming polarized light, controlling the passage of light;
(3) Color filters: Provide TFT LCD red, green and blue (three primary colors of light) sources;
(4) ITO transparent conductive layer: provide transparent conductive path;
(5) Photo Spacer: Provide a fixed height for color filters and TFT Glass Substrate. As a space for liquid crystal infusion, and as a support for the upper and lower Glass layers.
