If you subdivide the LCD module components, it can be divided into: polarizer, glass substrate, Black matrix, color filter, Protective film, Common electrode, LCD, Spacer, Display electrode, TFT, storage capacitor, glass Substrate, polarizing plate, diffuser plate, Prism sheet, light guide plate, lamp tube, reflector plate.
In addition, in a strict sense, the circuit that drives the backlight module is also a component of the LCD liquid crystal module.
The most complicated part of the above is the glass substrate, which is composed of two extremely thin glass with a micron-level gap in the middle, which is filled with liquid crystal molecules. Each pixel is an independent liquid crystal cell, and each liquid crystal cell has a micron-level gap. There is a control unit with electrodes connected to the substrate. It should be noted that each pixel here refers to one RGB instead of one RGB. Therefore, the physical resolution of the liquid crystal must be multiplied by 3 to be the real physical Unit pixels, some special ones like Sharp’s new "four-color" LCD panel, need to add "Y" (yellow) from RGB, and the physical unit pixels are 4 times the nominal resolution.....So, in the glass There are a large number of extremely thin electrodes and leads on the substrate, which are basically transparent and difficult to distinguish with the naked eye.
