Abstract

The embodiment of the invention provides a backlight module and a display device. The backlight module comprises a back plate, a light source array and a diffusion plate, wherein the light source array is arranged on the back plate and comprises a plurality of light source components; the diffusion plate is arranged on the light source array and is parallel to the light source array; refraction structures are arranged on the diffusion plate and are used for refracting light of the light source components; at least part of the refraction structures correspond to each light source component of the light source array. Through the adoption of the backlight module provided by the embodiment of the invention, solving the problem of uneven brightness caused by reduction of the number of light sources in the existing backlight module can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of backlight display equipment, and in particular relates to a backlight module and a display device. Background technique [0002] LCD TVs usually consist of a light source and a transparent panel with a picture. The transparent panel itself does not have luminescence, and another important component is needed for imaging display, that is, the backlight. The backlight module provides the backlight. Common light sources in the backlight module include cold cathode lamps and light emitting diodes, for example. Due to the advantages of low power consumption and high brightness of light-emitting diodes, backlight modules using light-emitting diodes as light sources have become a research direction in liquid crystal display technology. Backlight modules can be divided into direct-type backlight modules and side-type backlight modules according to the incident position of the light source. The direct-type bac...
