What Is The Principle Of LCD Display?

To put it simply, it is the structure: color filter polarized glass, liquid crystal sub-polarized glass, and back light. The polarization directions of the two polarized glasses are different. For a normal black screen, when it is not powered, the backlight emits polarized light with the same polarity as the polarized glass. Because there is no electricity at this time, the liquid crystal has no effect on the polarization of this light, so this light cannot Once through the polarized glass, the user can see nothing. After energizing, the liquid crystal will gradually change the polarity of the polarized light into the same polarity as the glass one, so that it can pass through the glass one, so that the user can see the light. The color is produced by the filter (R, G, B).
