Title:
HUD SYSTEM AND MULTI-SCREEN JOINED DIFFRACTION DISPLAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/165921
Kind Code:
A1
Abstract:
Provided is a HUD system, comprising an optical engine (110) and a diffractive projection screen (120); the optical engine (110) is used for outputting a target image onto a display surface of said optical engine; the optical engine (110) comprises a coherent light source (111), an image modulator (112), and a light diffusing device (113); the light diffusing device (113) is used for diffusing light, causing the beams emitted by each pixel on the display surface to be divergent; the diffractive projection screen (120) comprises a diffractive optical device (120a), used for forming a virtual image of the target image by means of diffracting light from the optical engine (110); the projection region of the light beams emitted by each pixel on the display surface on the diffractive projection screen (120) at least partially overlaps the projection region of the light beams emitted by a plurality of other pixels on the diffractive projection screen (120). Also disclosed is a multi-screen joined diffraction display system.
