Abstract

Official abstract text for this publication.

A backlight module and a display device are disclosed. The present disclosure relates to the technical field of display, whereby the technical problem of dark spots existing at the corners of the liquid crystal display device in the prior art can be solved. The backlight module comprises a reflective sheet and a plurality of light sources that are arranged on said reflective sheet, wherein the reflective sheet at edges and corners of said backlight module has a certain slope or curvature; and adjusting members, arranged at corners of said backlight module, so that the slope or curvature of the reflective sheet at the corners of said backlight module matches the slope or curvature of the reflective sheet at the edges of said backlight module.

First claim

Opening claim text (preview).

1 . A backlight module, comprising: a reflective sheet; a plurality of light sources that are arranged on said reflective sheet, wherein the reflective sheet at edges and corners of said backlight module has a certain slope or curvature; and adjusting members, arranged at corners of said backlight module, so that the slope or curvature of the reflective sheet at the corners of said backlight module matches the slope or curvature of the reflective sheet at the edges of said backlight module. 2 . The backlight module according to claim 1 , wherein said adjusting members are protrusions that are arranged below the reflective sheet at the corners of said backlight module. 3 . The backlight module according to claim 1 , wherein said adjusting members are reflective elements, which have a certain slope or curvature matching the slope or curvature of the reflective sheet at the edges of said backlight module. 4 . The backlight module according to claim 3 , wherein said reflective elements and said reflective sheet are connected with each other in a fixed manner. 5 . The backlight module according to claim 4 , wherein said reflective elements and said reflective sheet are connected with each other in a fixed manner by clamps or screw bolts. 6 . The backlight module according to claim 4 , wherein said reflective elements and said reflective sheet are connected with each other in a fixed manner by adhesive. 7 . The backlight module according to claim 1 , wherein said light sources are light-emitting diodes. 8 . The backlight module according to claim 1 , wherein said backlight module is a direct type backlight module. 9 . A display device, comprising a liquid crystal module and a backlight module, wherein said backlight module comprises: a reflective sheet and a plurality of light sources that are arranged on said reflective sheet, wherein the reflective sheet at edges and corners of said backlight module has a certain slope or curvature; and adjusting members, arranged at corners of said backlight module, so that the slope or curvature of the reflective sheet at the corners of said backlight module matches the slope or curvature of the reflective sheet at the edges of said backlight module. 10 . The display device according to claim 9 , wherein said adjusting members are protrusions that are arranged below the reflective sheet at the corners of said backlight module. 11 . The display device according to claim 9 , wherein said adjusting members are reflective elements, which have a certain slope or curvature matching the slope or curvature of the reflective sheet at the edges of said backlight module. 12 . The display device according to claim 11 , wherein said reflective elements and said reflective sheet are connected with each other in a fixed manner. 13 . The display device according to claim 12 , wherein said reflective elements and said reflective sheet are connected with each other in a fixed manner by clamps or screw bolts. 14 . The display device according to claim 12 , wherein said reflective elements and said reflective sheet are connected with each other in a fixed manner by adhesive. 15 . The display device according to claim 9 , wherein said light sources are light-emitting diodes. 16 . The display device according to claim 9 , wherein said backlight module is a direct type backlight module.
