4.3 Inch TFT With Touch Display
LCD (short for Liquid Crystal Display). The structure of LCD is to place a liquid crystal cell between two parallel glass substrates, set a TFT (thin film transistor) on the lower substrate glass, and set a color filter on the upper substrate glass. The rotation direction of liquid crystal molecules is controlled by changing the signal and voltage on the TFT, so as to control the emission of polarized light from each pixel to achieve the display purpose. LCD has replaced CRT as the mainstream, and the price has dropped a lot and has been fully popularized.
