2023-05-29

TFT (Thin Film Transistor) is a thin film field effect transistor, which means that each pixel point of the liquid crystal display is driven by a thin film transistor integrated in the back. This allows for high speed, high brightness, and high contrast display of screen information.

TFT belongs to a kind of LCD liquid crystal screen.

One DOT dot = three RGB pixels.

At present, we see the TN panel is mostly improved TN + film, film is compensation film, used to make up for the shortage of TN panel viewing angle, the current improved TN panel viewing angle of 160 °, of course, this is the manufacturer in the case of contrast ratio of 10:1 measured limit value, in fact, in the contrast ratio down to 100:1 when the image has been distorted or even off-color.

Color screens for cell phones vary depending on the quality of the LCD and research and development technology, and are available in STN (CSTN), TFT (LTPS), TFD, UFB and OLED.

LLCD (Liquid Crystal Display), that is, liquid crystal display. Generally are divided into monochrome and color LCD two, the current monochrome LCD has almost withdrawn from the notebook market, while the color LCD still continue to develop. Color LCD is mainly divided into STN and TFT two, which TFT (Thin Film Transistor) LCD, also known as the active electro-crystalline thin-film transistor liquid crystal display, which is commonly known by many people as the true color LCD; DSTN (Dual-Scn Twisted Nematic) LCD, that is, double-scan liquid crystal display. It is a display method of STN LCD, which has now been withdrawn from the market.
