What are the components of a liquid crystal display screen, and what effects the components will present? Today, I will learn about the components of a liquid crystal display screen with you.
1. Color filter substrate module
Also known as the opposite electrode substrate module or front substrate module. Composed of colored filters and transparent conductive films on a glass substrate, in addition to forming an orientation film on the surface of the transparent conductive film.
2. TFT array substrate module
Also known as pixel array substrate module or rear substrate module. Composed of polarizers and transparent conductive films on a glass substrate, in addition to forming an orientation film on the surface of the transparent conductive film.
3. Transparent conductive film
There are pixel electrodes formed by transparent conductive films on the TFT array substrate module, and opposite electrodes formed by transparent conductive films on the color filter substrate. By applying a voltage signal corresponding to the image data between two transparent electrodes, a liquid crystal shutter effect is generated.
4. Orientation film
A film layer that ensures the alignment and orientation of liquid crystal molecules in a certain direction. Generally, it is formed on a transparent conductive film by polyimide resin, and then subjected to directional friction and other treatments to produce orientation.
5. Polarizing film
Only allow light that vibrates in a specific direction to pass through. The polarizing film used in LCD displays can be divided into polarizing film and polarizing film.
6. Driving transistor
Each sub-pixel is equipped with a TFT that acts as a switch to control the voltage applied to the liquid crystal, thereby causing the liquid crystal to produce a shutter effect.
