The LCD module is simply a screen+backlight module. The display component of LCD TV is LCD module, and its low temperature is equivalent to the picture tube in CRT. Other parts include power supply circuit, signal processing circuit and, of course, shell and so on. The module is mainly divided into screen and backlight module. These two components are assembled together, but work independently of each other (that is, the circuits are not related). The principle of liquid crystal display is that the backlight module emits uniform surface light, and the light is transmitted to our eyes through the LCD screen. The function of the screen is to process the light pixel by pixel to display the image. Both parts contain a lot of parts, so I won't go into details here. At present, the best technology is Sharp, followed by Samsung Sony.
There are two kinds of liquid crystal modules, one is color liquid crystal; The second is monochromatic liquid crystal. Among them, monochromatic liquid crystals are divided into monochromatic graphic dot matrix liquid crystals, monochromatic character dot matrix liquid crystals and monochromatic customized pen segment liquid crystals.
Applications of LCD module: electric power measurement and control terminal, injection molding machine computer, numerical control system, man-machine interface, medical instruments, biochemical analysis, textile machinery control, tax control machine, lottery machine, food detection, chromatographic analysis, electronic measurement, environmental experimental equipment, fire safety, automotive electronics and data acquisition.
