What are the components of the LCD module

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. The English name is "LCD Module", abbreviated as "LCM", and Chinese is generally called "liquid crystal display module". In fact, it is a commercial component. According to my country's relevant national standards, only the integral parts 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.

The full English name of LCM is liquid crystal module, which refers to a liquid crystal display module, which usually includes LCD display drive circuits and interface circuits. It is often made into a module. Including LCD screen, iron frame, iron frame, PCB circuit board, driver IC, control IC, backlight, etc., among which IC packaging methods include hard packaging, COB bonding, and TAB packaging the IC on the film circuit , COF mounted IC fixed flexible circuit board, etc. There are also COG LCD that directly fix the IC on the glass of the LCD. LCM generally also includes a backlight (CCFL) and a driving circuit.

What are the components of the LCM module

The basic composition of LCM LCD module

It is composed of polarizer, backlight and control board. Among them, the liquid crystal is between the two glass LCM liquid crystal modules, which are mainly composed of glass, liquid crystal, and glass, and they do not emit light. According to the electro-optic effect, liquid crystal materials can be divided into two types: active liquid crystal and inactive liquid crystal. High light transmittance and controllability. The liquid crystal panel uses active liquid crystal, and people can control the brightness and color of the liquid crystal panel through the relevant control system. According to its characteristics, it can be divided into TN, STN, HTN, ESTN and TFT.

TN, STN, HTN. FSTN is mainly used in industries, such as telephones, POS machines, etc.; computers, mobile phones, etc. are all used TFT. From the display color can be divided into monochrome and color; the monochrome screen can be divided into Yellow-green, off-white, blue and other colors.
