How does TFT work? TFT is the abbreviation of "thin film transistor", which generally refers to thin film liquid crystal display, but actually refers to thin film transistor (matrix) - it can "actively" control each independent pixel on the screen, which is the origin of the so-called active matrix TFT. So how is the image produced? The basic principle is very simple: the display screen is composed of many pixels that can emit light of any color. As long as each pixel is controlled to display the corresponding color, the purpose can be achieved. Backlight technology is generally used in TFTLCD. In order to accurately control the color and brightness of each pixel, a switch similar to a shutter needs to be installed behind each pixel. When the "shutter" is opened, the light can be transmitted, but when the "shutter" is closed, the light cannot be transmitted. Of course, technically, the implementation is not as simple as that just mentioned.
