Title:
LIGHT GUIDE PLATE AND DISPLAY ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2024/000779
Kind Code:
A1
Abstract:
A light guide plate (33), comprising a bottom surface (11), a light exit surface (13) and a light incident surface (15). The bottom surface (11) and the light exit surface (13) are arranged opposite to each other. Furthermore, the light incident surface (15) connects the bottom surface (11) to the light exit surface (13). The bottom surface (11) has a plurality of microstructures, which comprise protruding structures (19) and recessed structures (17). The protruding structures (19) on the bottom surface (11) protrude towards the side distant from the light exit surface (13). The recessed structures (17) on the bottom surface (11) are recessed towards the light exit surface (13). The recessed structures (17) comprise first surfaces (171) facing the interior of the light guide plate (33). The first surfaces (171) face the light incident surface (15). The protruding structures (19) comprise second surfaces (191) facing the interior of the light guide plate (33). The second surfaces (191) are extended surfaces of the first surfaces (171). In the light guide plate and a backlight module, the area of an effective reflecting surface is increased, such that the light lead-out efficiency is increased. The protruding structures have the effects of anti-adsorption and anti-whitening at the top. A brightness enhancement film of the backlight module can be omitted, thereby reducing a film layer of the backlight module, simplifying the structure and assembly process, and also increasing the light energy utilization rate. Also provided is a display assembly comprising the light guide plate.
