Title:
OPTICAL IMAGING STRUCTURE AND HEAD-MOUNTED DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/181883
Kind Code:
A1
Abstract:
An optical imaging structure and a head-mounted display device. The optical imaging structure comprises: a display unit (100), an imaging assembly (200) and an elimination assembly (300), the display unit (100) is used for emitting a display light beam (110); the imaging assembly (200) is used for receiving a display light beam (110) emitted by the display unit (100) and propagating the display light beam (110) in the imaging assembly (200); the display beam (110) generates a ghost image light beam (111) when propagating in the imaging assembly (200); and the elimination assembly (300) is used for receiving the ghost image light beam (111), wherein the elimination assembly (300) has a first transmission direction, wherein the first transmission direction is different from the polarization direction of the ghost image light beam (111), so that a ghost image can be effectively eliminated, thereby improving the wearing experience of a user.
