Backlight module and display device

Abstract

The invention provides a backlight module which comprises a backboard, a light guide board and a rubber frame. The rubber frame comprises a plurality of rubber frame walls arranged around the light guide board, the backboard comprises a bottom wall and a plurality of side walls arranged around the rubber frame, and a light source is arranged between one rubber frame wall and the light guide board. A mounting block is arranged between the side wall, away from the light source, of the backboard and the light guide board, and the side face, towards the light guide board, of the mounting block protrudes out of the side, towards the light guide board, of the corresponding rubber frame wall so that the light guide board can be clamped between the light source and the mounting block. Correspondingly, the invention provides a display device. The relative stability of the light guide board and a light bar can be guaranteed, and the optical quality of the backlight module can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] The side-type backlight module is provided with a light guide plate, and the light source is installed on one side of the light guide plate to emit light into the light guide plate, and the light guide plate diffuses the light and is installed from the top surface to form a surface light source and provide it to the display panel. In the existing side-entry backlight modules, the combination between the light source and the light guide plate is mainly divided into two forms: one is in medium and large backlight modules such as vehicles, industrial control, and notebooks, the combination between the light source and the light guide plate There is a design gap between the light source and the light guide plate, which causes the distance between the light source and the light guide plate to be unstable or the li...

Problems solved by technology

In the existing side-entry backlight modules, the combination between the light source and the light guide plate is mainly divided into two forms: one is in medium and large backlight modules such as vehicles, industrial control, and notebooks, the combination between the light source and the light guide plate There is a design gap between the light source and the light guide plate, which causes the distance between the light source and the light guide plate to be unstable or the light guide plate is in a movable state in the backlight module, resulting in unstable optical quality of the backlight module and prone to poor luminance and light uniformity; One is that in small and medium-sized backlight modules such as mobile phones and feature phones, the light source and the light guide plate are pasted through a flexible circuit board. There are gaps between the light guide plates, which will also cause the above-mentioned defects such as luminance and light uniformity.
