Title:
VISUAL OPTICAL IMAGING SYSTEM AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/017908
Kind Code:
A1
Abstract:
A visual optical imaging system (100), comprising a refractive lens (10) and a reflective mirror (20). The refractive lens (10) comprises a light entrance surface (12) and a light exit surface (14). An imaging light enters from the side of the light entrance surface (12), and emits from the side of the light exit surface (14). After exiting, the imaging light enters the human eye (O) and forms a first image (C'). The reflective mirror (20) is arranged around the outer edge of the light exit surface (14), comprises a reflective surface (22), and is used for reflecting some of imaging light emitted from the light exit surface (14). The reflected imaging light enters the human eye and forms a second image (D'). The second image (D') is formed on the periphery of the first image (C'), and forms a complete image with the first image (C'). The visual optical imaging system (100) can be provided in head-mounted display devices such as a blindfold and a helmet. The reflective mirror (20) is arranged on the outer edge of the refractive lens (10), so that the imaging light that cannot be converged into the human eye (O) by means of the refractive lens (10) is converged into the human eye (O) by means of the reflective mirror (20) for imaging, which increases the field of view of a user and expand the visual range.
