Title:
BACKLIGHT MODULE AND DISPLAY DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/252941
Kind Code:
A1
Abstract:
A backlight module (100) and a display device thereof. A flexible circuit board (3) is connected to a step of a plastic frame (2), and is prevented from being adhered to a light guide plate (5) by means of an adhesive glue, shortening the distance between a light source (4) and an iron frame (1), thereby increasing the heat dissipation effect of the backlight module (100); besides, a barrier wall (6) is provided on two sides of at least one light-emitting unit (41) perpendicular to the plastic frame (2) and the top surface of the at least one light-emitting unit away from the iron frame (1), and a reflective membrane (7) is provided on the surface of one side of the barrier wall (6) facing the light-emitting unit (41), so as to collect and reflect light emitted by the light-emitting unit (41), such that the light emitted by the light-emitting unit (41) enters the light guide plate to a greater extent, avoiding light loss, thereby increasing the light-emitting efficiency of the backlight module (100), and reducing the production cost.
