Current Level Of TFT-LCD

- Jul 19, 2018-

(1) Both horizontal and vertical angles are up to 170 degrees;

(2) display brightness up to 500, contrast degree 500:1;

(3) Life span of more than 30,000 hours;

(4) field sequence full color (FSFC) technology began to be used in industrial production; (5) Large-screen thin film transistor LCD color TV (TFT-LC TV) has begun to enter large-scale industrial production, TFT-LCTV quality has reached or even exceeded the CRT, such as 28-inch TFT LC TV resolution is a 1920x1200, horizontal vertical angle of view are 170 degrees

38-inch TFT LC TV has been successfully developed, and 40-inch TFT-LCD has been successfully developed;

(6) Large-area low temperature polycrystalline silicon TFT-LCD has been successfully developed and put into industrial production, amorphous silicon TFT self-scanning LCD has been commercialized; (7) Reflective TFT-LCD color display began commercialization.

For example, the resolution is 400x234, the screen 16:9 of the 5.8-inch reflective display of the reflection rate of 30%, response speed of 30ms, the power consumption of 0.15 watts.

(8) 730x920mm large screen production line has been successfully developed, the larger size of the large screen production line is under construction. (9) The plastic substrate TFT-LCD began commercialization.

Japan's existing 5 varieties of plastic substrate products. (10) backlight and inverter, although in the active development of reflective LCD, but with backlight transmission type TFT-LCD in a very long time or mainstream products. Backlight is one of its important accessories. Germany developed into a flat-panel fluorescent lamp backlight for the LCD module, with a brightness of 5000-7000cd/m2 and a life expectancy of 100,000 hours. Some new self thermal backlight sources can work in the range of 40 ℃ to 85 ℃.

OEL backlight and high-brightness LED backlight has been successfully developed and used in TFT-LCD and linfinity.

Microelectrunies invented the long life inverter of the cold cathode backlight, and the light source modulation range reached 500:1.
