The liquid crystal display module is a component that assembles liquid crystal display devices, connectors, integrated circuits, PCB circuit boards, backlight sources, and structural parts together. In fact, it is a commercial component. Although it has a wide range of applications, many people still find it difficult to use and assemble. Especially for dot-matrix liquid crystal display devices, users will feel even more helpless. The special connection method and the required special equipment are not known and possessed by everyone. Therefore, the user of the liquid crystal display device hopes that someone will do it for them. The liquid crystal display device and the control and drive integrated circuit are assembled together to form a functional component. The user only needs It can be assembled into a complete system with traditional technology.

　　To put it simply, the LCD module is the screen + backlight board + PCB board + iron frame. The display components of power terminals, instrumentation, etc. are liquid crystal modules, which are equivalent to the picture tube in the CRT. Other parts include power supply circuits, signal processing circuits, etc., and of course the housing. The module is mainly divided into screen and backlight components. The two parts are assembled together, but they are independent of each other when working.

　　There is also a liquid crystal display module that is a component that assembles liquid crystal display devices, connectors, integrated circuits, PCB circuit boards, backlight sources, and structural components together. In fact, it is a commercial component. According to the relevant national standards of our country, only the integral components that cannot be split are called "modules", and those that can be split are called "components." Therefore, the standard name should be called "liquid crystal display assembly". But because people have been accustomed to call it "module" for a long time.
