LCD is relatively complex, and its main components include fluorescent tubes, light guide plates, polarizing plates, filters, glass substrates, alignment films, liquid crystal materials, thin-film transistors, etc. First, the LCD must use a backlight, that is, a fluorescent tube to project light. These light sources will first pass through a polarizing plate and then through liquid crystal. At this time, the arrangement of liquid crystal molecules will change the angle of light penetrating the liquid crystal. Then these light rays must also pass through the colored filter film in front and another polarizing plate. Therefore, we can control the intensity and color of the light that appears in the end by simply changing the voltage value that stimulates the liquid crystal, and then we can change the color combination of different shades on the LCD panel.
