Liquid crystal imaging requires three key components: backlight, liquid crystal display, polarizing film. When the backlight is turned on after the display is powered on, light (electromagnetic waves) emitted from the liquid crystal panel is transverse waves propagating in the forward direction and vibrations perpendicular to the forward direction (up, down, left, right), and is therefore referred to as "polarized light". The problem is that the human eye cannot recognize this "polarized light" and they see a white picture. The polarizing film is a dichroic transparent film on the surface of the liquid crystal screen, and can "convert" polarized light which cannot be recognized by human eyes into recognizable colors. One procedure in the production of LCD screens is to attach a polarizing film to the outer surface of the screen.
