LCD display technology, LCD display structure is very complicated, LCD is constructed by placing a liquid crystal cell in two parallel glass substrates, TFT (thin film transistor) on the lower substrate glass, color filter on the upper substrate glass, and TFT The signal and voltage changes on the liquid crystal molecules to control the direction of rotation of the liquid crystal molecules, so as to control the polarization of each pixel to exit or not for display purposes. According to the backlight source, the LCD display is divided into CCFL (Cold Cathode Fluorescent Tube) and LED (Light Emitting Diode). We generally think that the LCD and LED are the two types of display is wrong, it is completely the majority of manufacturers. Misleading, the two are just different backlight sources.
