What is the Production Process of Lcd Panel?

Whether the lcd panel can achieve 16.7M colors of true color display means that the three color channels of R.G.B (red, green and blue) have the ability to physically display 256 gray scales. Various factors such as output, quality and market environment are related to the quality, price and market trend of the LCD itself, because about 80% of the cost of an LCD is concentrated on the panel.

What are the main components of the lcd panel?

The lcd panel is mainly composed of the following eight parts: backlight (or backlight module); since the liquid crystal molecules themselves cannot emit light, if the picture is to appear, the liquid crystal display needs a special light source to provide light, and then deflected by the liquid crystal molecules to produce different colors. The backlight plays the role of providing light energy. In the past, LCD monitors used cold cathode ray tubes called CCFL, whose light-emitting principle is almost the same as that of fluorescent lamps, but now new LCD monitors use LED backlights that are more energy-saving and have a longer life. After the light tube (or LED) emits light, the light is distributed everywhere through the light guide plate, and the direction of all the light is concentrated towards the liquid crystal molecules through the reflector on the back.

What is the production process of lcd panel?

When producing LCD TVs, the TFT LCD screen must be combined with other components to exist as a whole. This is because the lcd panel itself is special, and special tools are required for connection and assembly, and the operation technology is very difficult, so the manufacturer puts the LCD screen, connector (interface), drive circuit PCB, backlight and other components The device is closed with a steel plate, leaving only the backlight, plug and drive circuit input socket. This component is called LCDMODULE (LCM), also known as liquid crystal display module, liquid crystal panel, liquid crystal panel, etc. It can be seen that this assembly method not only increases the reliability of work, but also prevents unnecessary accidental losses caused by random disassembly by users. Manufacturers of liquid crystal color TVs only need to connect the plug of the backlight and the socket of the driving circuit with the external circuit board, and the production process of the whole machine becomes much simpler.

What is the function of the backlight in the lcd panel?

The backlight in the lcd panel generally needs high voltage, which is generated by the high-voltage board circuit (also called inverter) outside the module and sent to the backlight through the high-voltage plug. According to the size of the lcd panel and display requirements, the number of backlights is different. Generally, there are less than 10 light tubes for small-screen LCD color TVs, and more than 10 light tubes for large-screen LCD color TVs.
