Example Embodiment

[0026] The specific embodiments of the present invention will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] As an aspect of the present invention, a backlight module is provided, such as figure 1 As shown, the backlight module includes a back plate 10, a light guide plate 20, and a plastic frame 30. The plastic frame 30 includes a plurality of plastic frame walls 31 arranged around the light guide plate 20, and the back plate 10 includes a bottom wall 11 and a plastic frame 30 arranged around. A light source 40 is provided between one of the plastic frame walls 31 and the light guide plate 20, and a mounting block 50 is also provided between the side wall of the back plate 10 far from the light source 40 and the light guide plate 20. The side surface facing the light guide plate...

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...
