Backlight module

Abstract

The invention discloses a backlight module, and the backlight module comprises a light guide plate and a reflection piece. The light guide plate is provided with a first main surface and a second main surface, which are opposite to each other. The light guide plate is also provided with a plurality of side surfaces. The second main surface and the side surfaces are connected through inclined surfaces. The reflection piece comprises a negative film disposed on the second main surface, at least one fin disposed on the side surfaces, and buffering pieces disposed on at least one corresponding inclined surface, wherein there are spaces between the buffering pieces and the corresponding inclined surfaces. The reflection piece also comprises a first weakening structure which is connected with the fins and the buffering pieces, and a second weakening structure connected with the buffering pieces and the negative film.

Description

technical field

[0001] The invention relates to a backlight module. Background technique

[0002] A flat panel display mainly includes components such as a backlight module, a display panel, and a frame. The backlight module is used to provide a light source so that the display panel can provide images with normal and uniform brightness. There are a plurality of optical sheets in the backlight module, such as a light guide plate, a diffusion sheet, a reflection sheet, and a prism sheet, etc., which are used to uniformly distribute the light emitted by the light source on the display panel to provide images. The outer frame includes a metal bracket and a plastic outer frame for fixing the display panel and the backlight module.

[0003] However, the light source in the backlight module will inevitably generate a large amount of heat, and it will also undergo some environmental temperature changes during the transportation of the flat-panel display. Because the material of t...
