Title:
OPTICAL DIAPHRAGM AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/070751
Kind Code:
A1
Abstract:
An optical diaphragm (20) and a display device. The optical diaphragm (20) comprises: multiple optical structures (21), multiple cambered surfaces (2142) being provided on the side of each optical structure (21) deviating from a display surface, the cambered surfaces (2142) being used for reflecting at least part of ambient light, and each optical structure (21) having a first refractive index; and a filing part (23), filling between the multiple optical structures (21), the filling part (23) having a second refractive index greater than the first refractive index. The reflecting angle of the ambient light can be adjusted by adjusting the curvature of the cambered surfaces (2142).
