Document Type and Number:
WIPO Patent Application WO/2019/134198
Kind Code:
A1
Abstract:
A backplate (10), a backlight module (100) comprising the backplate (10), and a liquid crystal display device comprising the backlight module (100). The backplate (10) comprises: a bracket (11) comprising a bracket bottom (111) and bracket sidewalls (112) provided on the sides of the bracket bottom (111), an opening (113) being provided on the bracket bottom (111), and the end of each bracket sidewall (112) against the bracket bottom (111) being used for connecting to a middle frame (50); and a substrate (12) detachably sealing the opening (113), the surface of the substrate (12) facing the bracket (11) being used for mounting a light emitting part (20), and the surface of the substrate (12) against the bracket (11) being used for mounting a heat dissipating part (70). According to the liquid crystal display device, when a same liquid crystal panel uses different backlight brightness or needs to adapt to a different temperature condition, the heat dissipation problem can be efficiently resolved by only replacing a substrate without changing the other structures, and the costs can be greatly reduced.
