1. LCD module
Glass substrate: Inside are liquid crystals and grid like printed circuits. Timing control: used to generate the timing and voltage required to control the deflection of liquid crystal molecules. Lamp tube: produces a white light source. Backlight: Reflect the light generated by the lamp onto the LCD screen.
2. Control board
The control board plays a signal conversion role. Convert signals in various input formats into signals in fixed output formats. For example, the input signal for a 1024 x768 screen can be 640 × 480, 800 × 600, 1024 × 768, etc., ultimately converted to output format 1024 × 768 [3].
3. Inverter
Generate high voltage to light up the lamp tube
