Document Type and Number:
WIPO Patent Application WO/2023/125548
Kind Code:
A1
Abstract:
A backlight structure (200), a display, and an electronic device. The backlight structure (200) comprises a light source layer (201), a light functional structure layer, and a brightness enhancement film structure layer. The light source layer (201), the light functional structure layer and the brightness enhancement film structure layer are stacked in a first direction. The brightness enhancement film structure layer comprises at least one brightness enhancement film layer (205, 206), each brightness enhancement film layer (205, 206) in the at least one brightness enhancement film layer (205, 206) comprises a substrate (2051, 2061) and a prism column layer (2052, 2062) which are connected in a stacked manner, and the prism column layer (2052, 2062) comprises at least one protrusion structure provided on the substrate (2051, 2061). Therefore, a light emitting angle of the brightness enhancement film structure layer is effectively improved, the overall brightness of the display during large-angle watching is improved, and wide-view-angle display of the display is achieved.
