Title:
DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/197294
Kind Code:
A1
Abstract:
The present disclosure provides a display device. The display device comprises: an optical imaging apparatus comprising an image source element, a splitting element and a reflecting element which are configured for optical path alignment; and an absorption element, the shape of the absorption element and the arrangement position of the absorption element in the display device enabling the absorption element to absorb non-imaging light in a scene to be displayed without shielding imaging light used for generating a display image of the scene. In the display device, the absorption element absorbs the non-imaging light in the scene to be displayed, reducing the non-imaging light in the display device, and thereby reducing the influence of the non-imaging light on the scene and improving the display quality of the display image of the scene.
