Understanding the Working Principle of LCD Screens

Reflector: Recovers light and reflects it back to enhance brightness.

Light Guide Plate: Converts linear light sources into surface light sources through various densities and sizes of light guide points, allowing for uniform illumination.

Diffusion Film: Enlarges the area of light diffusion, making the light softer.

Prism Film: The prism film has small angled ridges on its front surface, allowing only light at certain angles to pass through while reflecting light that does not meet the angle requirements.

Bottom Polarizer: Only allows vertical light waves to pass through, blocking all other light waves.

Thin Film Transistor (TFT): A type of transistor that controls the voltage of each sub-pixel, thereby controlling the twisting of liquid crystal molecules and the brightness of the sub-pixels.

Liquid Crystal Layer: Acts like a regulating valve.

Common Electrode: Used to apply voltage to the liquid crystal layer, maintaining the voltage across the entire pixel.

Color Filter Film: Composed of red, green, and blue, allowing the LCD screen to display a variety of colors.

Top Polarizer: Only allows horizontal light waves to pass through, blocking all other light waves.
