The LCD module is simply a screen + backlight assembly. The display part of an LCD TV is a liquid crystal module, and its status is equivalent to a picture tube in a CRT. The other parts include the power supply circuit, signal processing circuit, etc., and of course the shell or something. The module is mainly divided into screen and backlight components. The two parts are assembled together, but work independently of each other (ie the circuits are not related).
There are two main types of liquid crystal modules, one is color liquid crystal; the other is monochrome liquid crystal. Monochrome LCD is divided into monochrome graphic dot matrix LCD screen, monochrome character dot matrix LCD screen, and monochrome custom pen LCD screen.
Application of LCD module: power measurement and control terminal, injection molding machine computer, numerical control system, human-machine interface, medical equipment, biochemical analysis, textile machinery control, tax control machine, lottery machine, food testing, chromatography analysis, electronic measurement, environmental experiment equipment , Fire safety, automotive electronics and data acquisition.
