Abstract

The invention discloses a side-into type backlight module and a display device. The side-into type backlight module comprises a light guide plate, a plurality of light sources, and dark area compensation units which are arranged between the adjacent two light sources, wherein light from each light source goes into the light guide plate from the side surface, and the light uniformly goes out from the front surface of the light guide plate through the action of the light guide plate, and the dark area compensation units are used for providing light compensation for the dark areas between the two adjacent light sources. The dark area compensation units are arranged between the adjacent two light sources, so that the side-into type backlight module can effectively solve the dark area effect, and the defects of the dark area effect in the prior art can be conquered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an edge-type backlight module and a display device. Background technique [0002] Liquid crystal display is a passive light emitting device Therefore, it is necessary to design a special structure to provide a light source for it. The backlight module is a device that provides light sources for liquid crystal display devices. The working method of the backlight module is to convert the incoming line light source or point light source into a uniform outgoing surface light source Take the backlight module studied in this paper as an example Generally, it includes light source, reflective layer, light guide plate, diffusion film, prism sheet, brightness enhancement film, etc. [0003] Backlight modules can be divided into side-type backlight modules and direct-type backlight modules according to the placement of light sources. Displays such as TVs and high-brightness monit...
