Abstract

A backlight module (100) comprising a back panel (110) and a light source (120). The back panel (110) comprises multiple back panel protrusions (113) and back panel indentations (114) corresponding thereto. The light source (120) is arranged on the back panel (110) and among the back panel protrusions (113). Also disclosed is a display device. The display device comprises the backlight module (100) and a display panel (101). The backlight module (100) and the display device are capable of utilizing the back panel indentations (114) to improve heat-dissipation effects.

Description

【Technical field】 [0001] The invention relates to a backlight module and a display device, in particular to a backlight module and a display device capable of improving heat dissipation efficiency. 【Background technique】 [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which are composed of a liquid crystal display panel and a backlight module. The backlight module can be divided into side-light type and direct-light type according to the incident position of the light source, so as to provide backlight to the liquid crystal display panel. [0003] Since the heat generated by the liquid crystal display during operation will affect the performance of the liquid crystal display, the heat dissipation method of the liquid crystal display is very important. In the direct type backlight module, the light source is, for example, a light emitting diode (Light Emitting Diode, LED), which is disposed on...
