Title:
NEAR-TO-EYE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/048661
Kind Code:
A1
Abstract:
A near-to-eye display device, comprising an optical machine (105) and a light guide framework (101). The optical machine (105) is used for generating target light rays; the light guide framework (101) comprises two or more light guide plates; the target light ray generated by the optical machine (105) is divided into light rays of multiple fields of view (FOVs); and each light guide plate transmits light rays of some of the FOVs. The number of times that the incident light hits a grating is reduced by means of the multiple light guide plates, thereby reducing the energy loss.
