Abstract

The invention provides a backlight module and a display device. The backlight module comprises a light guide plate and incidence light sources. The light guide plate comprises a reflection face, light incidence faces and a light outgoing face. The light incidence faces are located on the lateral sides of the light guide plate. The reflection face and the light outgoing face are oppositely arranged. A plurality of dots are arranged on the reflection face. The incidence light sources and the light incidence faces are oppositely arranged. The incidence light sources are white light sources. The dots include the red dots, the green dots and the blue dots. By means of the backlight module and the display device, the white backlight sources with the high purity and the even colors can be provided for a liquid crystal display panel.

Description

technical field [0001] The invention relates to display technology, in particular to a backlight module and a display device. Background technique [0002] At present, with the development of electronic technology and the improvement of consumers' requirements for TV size and picture quality, LCD TV has become the mainstream development trend in the industry. [0003] At present, the backlight modules in LCD TVs usually include side-light backlight modules. The side-light backlight modules include an incident light source and a light guide plate. The incident light source is generally a white light-emitting diode (LED), and the light emitted by the white LED The light enters from the light incident side of the light guide plate, and is reflected and diffused by the dots on the light guide plate, thereby forming a surface light source on the light output side of the light guide plate. The dots of the existing light guide plate are often printed with black ink. The ink can be...
