What is the main component and material application of the liquid crystal module (LCM)?
Jan 25, 2019
Liquid crystal modules (LCM) constitute the main components and materials applications
1. Polarizing plate: The most important thing is as a grating, which only allows light in a single direction to pass, and also protects the CF layer and the TFT layer.
2. CF layer and TFT layer: one up to form an electric field, let the liquid crystals align under this electric field.
3. Alignment (PI) film: the alignment film has directional properties to allow the liquid crystal to be regularly arranged on the alignment film.
4. Transparent metal conductive layer (ITO): energizes the upper and lower glass to control the liquid crystal direction
5. Frame glue: Just like the wall of a house, it is used to prevent the liquid crystal from coming into contact with the outside world.
6. SPACER: Just like the pillar of a house, it is used to support the upper and lower substrates.
7. Liquid crystal: The arrangement of liquid crystals is controlled under different electric fields to obtain the light quantity with different transmittance, thereby achieving the display principle.
8. Backlight module: provide a backlight to display the signal changes of the LCD
