Micro LCD panel, you will see red, green, and blue for a group of three primary colors, generally a group or two groups for a pixel It is roughly shaped like a sandwich, with an LCD sandwiched between a layer of TFT glass and a layer of colored filters. The LCD plate is thin and translucent without electricity. In addition, there is a driving IC and printed circuit board beside the LCD panel, which is mainly used to control the rotation of LCD molecules in the LCD panel and the transmission of display signals. The LCD plates are horizontal polarizer, color filter, LCD, TFT glass, and vertical polarizer from outside to inside.

LCD plate in the case of no current translucent state These include backlight plates, backlight sources (CCFL or LED), diffuser plates (to distribute light evenly), diffuser plates, and so on.ĭue to the LCD does not shine, so you need to use another light source to illuminate, the function of the backlight system is to this, but currently used CCFL lamp or LED backlight, don’t have the characteristics of the surface light source, so you need to guide plate, spreadsheet components, such as linear or point sources of light evenly across the surface, in order to make the entire LCD panel on the differences of luminous intensity is the same, but it is very difficult, to achieve the ideal state can be to try to reduce brightness non-uniformity, the backlight system has a lot to the test of design and workmanship.

The general structure of the LCD panel is not very complex, now the structure of the LCD panel is divided into two parts: the LCD panel and the backlight system.

The whole process needs to be carried out in a dust-free environment and with precise technology. The production and manufacturing process of the LCD panels is very complicated, requiring at least 300 process processes. The LCD panel, the main control circuit, shell, and other parts of the main assembly, basically will not have too complex technical problems.ĭoes this mean that LCDS are low-tech products? In fact, it is not. The production of civil LCD displays is just an assembly process. And account for an LCD display 80% of the cost of the LCD panel, enough to show that the LCD panel is the core part of the entire display, the quality of the LCD panel, can be said to directly determine the quality of an LCD display. Important technical improvements of LCD, such as LED backlighting and wide viewing Angle, are directly related to LCD.
