The screen display content forms such as text, animation, picture, and video are converted in time through the disappearance of the red and green light beads, and the display control is controlled by the structure display component.

2. LCD: The direction of the liquid crystal molecules is controlled by the signal and voltage changes on it, so as to achieve the purpose of controlling whether the pixel emits light or not.

3. TFT: The imaginary light source path using "transparent" photography is not a TN picture, but from top to bottom, from bottom to bottom. The polarizing plate penetrates upward.
