Abstract

The invention discloses a backlight source structure and a display device. The backlight source structure comprises a back board, a rubber frame, an optical film material and a first light source, wherein the back board comprises a bottom plate and a side wall which is vertical to the bottom plate; the rubber frame is arranged on the side wall; the rubber frame comprises a plane support part which is used for supporting the optical film material; the first light source is located on the bottom plate and corresponds to the plane support part; a through hole is formed in the plane support part; light emitted from the first light source can be transmitted to the optical film material through the through hole. According to the backlight source structure, the edge shading phenomenon easily generated by a display panel is avoided; the effects of improving the effective display area of the display panel and the visual experience of a user are achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight source structure and a display device. Background technique [0002] At present, narrow bezel designs such as splicing screen displays are becoming more and more popular. Narrow bezel design refers to the design method in which the width of the Module Bezel (module bezel, that is, the front frame) is smaller than that of conventional products. This design method can increase the effective display area of ​​the product and improve The visual impact of users is the direction of efforts of major manufacturers at present. [0003] Although narrow bezel products are eye-catching, they still have many problems. For example, the phenomenon of edge darkening is mostly reflected in direct-lit backlight products. In direct-lit backlight products, the frame glue includes parts parallel to the diffuser plate, which are used to support optical films such as the diffuser plate. ...
