Abstract

The invention provides a backlight module and a display device; the backlight module comprises a light guide plate and a first reflector plate, the light guide plate comprises a light outgoing surface, a light incoming surface and a plurality of light guide plate side surfaces, and the first reflector plate is arranged on the light guide plate side surfaces; the first reflector plate comprises a reflecting layer and a light control layer, and the light control layer is arranged on the side, close to the light guide plate, of the reflecting layer; the light control layer comprises a plurality of light absorption pieces, and the light absorption pieces are arranged at intervals in the direction perpendicular to the light emitting surface; every two adjacent light absorption pieces form a light control interval, and the light control intervals are used for absorbing light with the first incident angle larger than a preset critical angle; a first reflecting sheet comprising a reflecting layer and a light control layer is arranged on the side edge of a light guide plate; the light control layer of the first reflector plate is provided with a plurality of light control intervals formed by the light absorption pieces, each light control interval can absorb light with the first incident angle larger than the preset critical angle so as to prevent the light from being emitted out of thenarrow frame area, and therefore the problem of light leakage of the side edge of the narrow frame display panel is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a backlight module and a display device. Background technique [0002] With the development of technology and the improvement of consumers' appearance requirements, the traditional backlight module with front frame and back cover can no longer meet the needs of high-end consumers. The R&D personnel of many display manufacturers continue to make breakthroughs in narrow bezels and ultra-thin aspects. Obvious results have been achieved so far. Among them, the main factor affecting the border size is the width of the BM region. BM (Black Matrix) is called black matrix or "black border", located around the liquid crystal display panel, and its main function is to route the panel pixel data signal and scan signal and prevent backlight leakage. [0003] With the development of technology, GOA (Gate Driver On Array, row-driven array subst...
