What is the LCD module

The LCD module is simply a screen + backlight module. The display component of LCD TV is the LCD module, which is equivalent to the picture tube in CRT. Other parts include power supply circuit, signal processing circuit, and of course, the housing. The module is mainly divided into screen and backlight module. The two parts are assembled together, but they work independently of each other (i.e. the circuit is not related).

The principle of LCD is that the backlight module emits uniform surface light, which is transmitted to our eyes through the LCD screen. The function of the screen is to process these lights by pixels to display images. Both parts contain a large number of components.
