What components are the LCD screens mainly composed of?
LCD LCD module main components to be used are: LCD panel, IC, backlight, TP, FPC.
If the LCD module components are subdivided, they can be divided into: polarizing plate, glass substrate, Black matrix, color filter, protective film, Common electrode, liquid crystal, Spacer, Display electrode, TFT, storage capacitor, glass. Substrate, polarizing plate, diffusing plate, Prism sheet, light guide plate, tube, reflector.
LCD liquid crystal module

In addition, in a strict sense, the circuit for driving the backlight module is also a component of the LCD liquid crystal module.
The above complex part of the glass substrate is composed of two extremely thin glass with a micron-scale gap in the middle, filled with liquid crystal molecules, each pixel is an independent liquid crystal cell, and each liquid crystal cell has The electrode is connected to the control unit on the substrate. It should be noted that each pixel here refers to one RGB, not one RGB, so multiplying the physical resolution pixel of the liquid crystal by 3 is the real physical unit. Pixels, some special "four-color" LCD panels like Sharp's new one, plus RGB plus "Y" (yellow), physical unit pixels are 4 times the nominal resolution..... So, on the glass substrate There are a large number of extremely fine electrodes and leads, which are basically transparent and difficult to distinguish with the naked eye.
