Abstract
A display system and a display control method of the display system are provided. The display system includes a display device, at least two layers of liquid crystal cells on a light-emitting side of the display device, and a controller device. The display device is configured to display a display picture; the at least two lavers of liquid crystal cells are configured to control an exit angle of light of the display picture; the controller device is configured to control positions and/or widths of light-transmitting regions and light-shielding regions of each layer of the liquid crystal cells to control a display mode of the display picture. The display system can control the positions and widths of the light-transmitting regions and the light-shielding regions formed on each liquid crystal cell according to actual needs, thereby realizing switching among various display modes.
