Thin film transistor (TFT) is one of the active matrix type liquid crystal display (am-lcd). TFT has a special light tube on the back of the liquid crystal, which can "actively" control each independent pixel on the screen. This is the origin of the so-called active matrix TFT, which can greatly improve the reaction time. Generally, the reaction time of TFT is relatively fast, About 80 ms and 200 ms for STN, If we want to improve it, there will be flicker.
and because TFT is an active matrix LCD, it can make the arrangement of liquid crystal have memory.

What's the difference between TFT and TFT-LCD and LCD?

it will not return to its original state immediately after the current disappears.
TFT also improves the flicker (water ripple) - blur phenomenon of STN, and effectively improves the ability of playing dynamic pictures.
compared with STN.
TFT has excellent color saturation, color stability and color stability LCD: liquid crystal display.
LCD is mainly divided into monochrome, false color, true color and so on.
TFT is a kind of LCD.
also known as true color screen.
it is better than the other two in brightness and viewing angle (1) both horizontal and vertical angles have reached 170 degrees
(2) the display brightness reaches 500 nits.
the contrast is 500:1
(3) the service life is more than 30000 hours<(4) FSFC technology has been applied in industrial production
(5) Large screen thin film transistor liquid crystal display color TV (tft-lctv) has begun to enter large-scale industrial production.
the image quality of tft-lctv has reached or even surpassed CRT, for example, the resolution of 28 inch tft-lctv is 1920 × 1200, horizontal and vertical viewing angles are 170 degrees; The 38 inch TFT LC TV has been successfully developed; 40 inch TFT-LCD has also been developed successfully<(6) large area low temperature polycrystalline silicon TFT-LCD has been successfully developed.
and put into industrial production, the self scanning LCD of amorphous silicon TFT has been commercialized<(7) reflective TFT-LCD color displays are commercialized.
for example, the resolution is 400 × 234.
the reflectivity of the 5.8-inch reflective display with 16:9 screen is 30%, the response speed is 30ms, and the power consumption is 0.15w.
(8) 730 × 920 mm substrate large screen production line has been developed successfully.
large screen production line for larger size substrate is under construction.
(9) plastic substrate TFT-LCD is commercialized.
there are five kinds of plastic substrate products in Japan.
(10) backlight and inverter.
although reflective LCD is being actively developed, However, the transmission TFT-LCD with backlight is still the mainstream product for quite a long time.
backlight is an important part of TFT-LCD.
the backlight of flat fluorescent lamp used in LCD module has been developed in Germany.
the brightness can reach 5000-7000cd / m2 and the service life can reach 100000 hours.
some new self heating backlights can work normally in the range of - 40 ℃ to 85 ℃OEL backlight and high brightness LED backlight have been developed successfully.
and began to be used in TFT-LCD and linfinity.
microelectrotronies invented the cold cathode backlight long life inverter.
the light source modulation range reaches 500:1.
