TFT type liquid crystal displays are relatively complex, mainly composed of fluorescent tubes, light guide plates, polarizers, filter plates, glass substrates, alignment films, liquid crystal materials, thin mode transistors, and so on. Firstly, a liquid crystal display must first use a backlight, which is a fluorescent tube to project a light source. These light sources will first pass through a polarizing plate and then through the liquid crystal. At this time, the arrangement of the liquid crystal molecules will change the angle of light passing through the liquid crystal. Then, these light rays must pass through the colored filter film and another polarizing plate in front of them. Therefore, as long as we change the voltage value that stimulates the LCD, we can control the final light intensity and color that appears, and can then change color combinations with different shades on the LCD panel
