Title:
DISPLAY DEVICE AND DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2022/193847
Kind Code:
A1
Abstract:
A display device and a display method. The display device comprises an image source (100), an optical array (200), and a coupling lens (300). The image source (100) comprises multiple display sub-areas (110); the optical array (200) is located on a light-emitting side of the image source (100), and comprises multiple optical structures (210) arranged in an array; and the coupling lens (300) is located on the side of the optical array (200) distant from the image source (100). The multiple display sub-areas (110) have one-to-one correspondence to the multiple optical structures (210), and image light emitted from each display sub-area (110) is configured to be incident to the coupling lens (300) through the corresponding optical structure (210). Each optical structure (210) forms an optical channel; the image light emitted from each display sub-area (110) is configured to be emitted from the corresponding optical channel; the directions of main light of beams emitted from different optical channels are different; and the maximum angle of included angles between every two adjacent directions of the main light of the beams emitted from different optical channels is 110-130°. Thus, the light emitted from each display sub-area (110) can be adjusted and optimized by individually adjusting parameters of different optical channels.
