LCD module is a kind of liquid crystal displays, connectors, integrated circuit, PCB circuit board, backlight, the structure of the components assembled together. English name is "LCD Module", referred to as the "LCM", the Chinese general known as "liquid crystal display module." In fact, it is a commercial component. According to the provisions of the relevant national standards: the integration of only the non-split components are called "modules" can be split called "component." Therefore, it is called standard should be called "liquid crystal display components." But because people are accustomed to call it a long time "module."

LCD display is the basis of a high-tech components, although the application of Pat very broad, but for many people, use, assembly is still very difficult. Particular point of formation liquid crystal display, the user will feel it is impossible to start. Special connections and special equipment needed is also inhuman people understand and have, therefore liquid crystal display device, the user wants someone do it, the LCD display and control, driver IC fit together to form a functional unit, the user simply with the traditional process can be assembled into a whole system.

Broadly speaking, all the liquid crystal display devices and integrated circuits, components are assembled together in a "module", but in practice we usually call "modules" mainly refers to the dot matrix liquid crystal display assembly of the dot matrix LCD module particularly because it is dot matrix liquid crystal display products in addition to large quantities of some dedicated some species (such as translation machines, communication), manufacturers supply directly to the user liquid crystal display, almost all general-purpose LCD display is dot matrix processed into the module after the supply to the users, so it is easy to form "LCD module" is the "dot-matrix LCD modules" misunderstanding.
