Abstract

The invention provides a backlight module and a display device. The display device comprises the backlight module and a display panel. The backlight module comprises a housing, a light guide plate and a light source, wherein the light guide plate is arranged in the housing and is provided with a light-emitting surface and a positioning convex part; the positioning convex part protrudes out of the light-emitting surface; and the light source is arranged on at least one side of the light guide plate. In the invention, the assembly structure and the assembly process of the display device can be simplified through the utilization of the positioning convex part.

Description

【Technical field】 [0001] The present invention relates to a backlight module and a display device, in particular to a side light incident backlight module and a display device. 【Background technique】 [0002] Liquid crystal displays (LCDs) have been widely used in various electronic products. Most of the liquid crystal displays are backlight type liquid crystal displays, 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] Usually, the liquid crystal display panel of the liquid crystal display is supported by a plastic frame on the backlight module, and a front frame is used to assemble the liquid crystal display panel on the backlight module. However, this assembling method consumes more manpower and time, and requires more parts (plastic frame ...
