the polarizing plate, the light will be polarized, and the polarized light will pass through the liquid crystal. 

Because the arrangement of the liquid crystal molecules is affected by the voltage generated by the electrode, 

the liquid crystal can change the polarizing angle of the polarized light. The light intensity caused by different 

polarizing angles will be different, and the light with different intensity will be different After the red, blue and 

green elements of the color filter, various brightness and color elements will be displayed. Finally, all kinds 

of images and figures can be formed through each pixel.
