Abstract

The embodiment of the present application provides a backlight module and a display device. The backlight module forms a groove in the area of ​​the backplane corresponding to the gap between the lamp panels, and forms a heat dissipation structure in the groove, so that the heat dissipation in the gap is enhanced, and The heat dissipation structure can increase the strength of the backplane, and the ribs on the back of the backplane formed by the grooves can further increase the strength of the backplane, thereby increasing the heat dissipation in the corresponding area of ​​the lamp board gap, and at the same time, improving the strength of the backplane and alleviating the In the existing backlight module, there is a technical problem that the temperature at the gap between the lamp panels is relatively high, resulting in uneven display.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] With the development of liquid crystal display technology, in the existing large-size display devices, multiple small light panels will be spliced ​​to form glass light panels in the backlight design. However, during the splicing process, the adjacent small light panels There must be a certain gap between the small lamp panels, and the gap will be filled with air, and the heat conduction of the air is small, resulting in a higher temperature in the gap between the small light panels, resulting in uneven display and poor display quality. [0003] Therefore, the existing backlight module has a technical problem of high temperature at the gap between the lamp panels, resulting in uneven display. Contents of the invention [0004] Embodiments of the present application provide a backlight module and ...
