Document Type and Number:
WIPO Patent Application WO/2024/040725
Kind Code:
A1
Abstract:
A backlight module (B) and a display device. The backlight module (B) comprises an outer frame unit (2), a light guide plate (4) disposed in the outer frame unit (2), a light-emitting unit (5), a plurality of fixing adhesives (6) for fixing the light-emitting unit (5) on the light guide plate (4), and a plurality of abutting structures (7). The light-emitting unit (5) comprises a flexible circuit board (51) and a plurality of light-emitting members (52) arranged on the flexible circuit board (51) at intervals. By means of the abutting structures (7), the flexible circuit board (51) deforms at a specific position, and the positions of the light-emitting members (52) relative to the light guide plate (4) can be adjusted, so that the light-emitting members (52) can be aligned with the light incident surface of the light guide plate (4), thereby preventing light from leaking out from the position of the light exit surface of the light guide plate (4) close to the light-emitting members (52), reducing generation of bright lines, and improving the overall uniform brightness.
