How TFT works TFT is the abbreviation of "Thin Film Transistor", generally refers to thin film liquid crystal displays, but actually refers to thin film transistors (matrix)-can "actively" each independent pixel on the screen Control, this is the origin of the so-called active matrix TFT (active matrix TFT). So how exactly is the image produced? The basic principle is simple: the display screen is composed of many pixels that can emit light of any color, and the purpose can be achieved by controlling each pixel to display the corresponding color. In TFT LCD, backlight technology is generally used. In order to accurately control the color and brightness of each pixel, it is necessary to install a shutter-like switch after each pixel. When the "blinds" are opened, light can pass through, and " When the shutters are closed, light cannot pass through. Of course, technically, it is not as simple as the one just mentioned. LCD (Liquid Crystal Display) uses the characteristics of liquid crystals (liquid when heated, and crystallized into solid when cooled)
The TFT liquid crystal display is characterized by good brightness, high contrast, strong sense of hierarchy, and bright colors, but it also has the disadvantages of relatively power consumption and high cost. TFT LCD technology has accelerated the development of mobile phone color screens. Many of the new generation of color-screen mobile phones support 65536 color displays, and some even support 160,000 color displays. At this time, the advantages of TFT's high contrast and rich colors are very important.
