Patent ID: 10234718

Abstract:
Embodiments of the present disclosure provide a display device and virtual reality glasses. The display device comprises an array substrate, which comprises a base substrate, a plurality of sub-pixels arranged on the base substrate, and a grating arranged on the base substrate. The grating comprises a plurality of sub-gratings having different structures, and each sub-grating comprises an adjusting part for adjusting propagation direction of light rays, so that light rays exiting from the adjusting part converge to a predetermined spatial position. The array substrate further comprises a plurality of preset areas, and the plurality of sub-gratings correspond to sub-pixels located in different preset areas respectively. The display device further comprises a light source disposed beside the base substrate. The light rays emitted from the light source are parallel light. The light rays are totally reflected in the array substrate except in regions where the adjusting parts of sub-gratings are located.
