Problems solved by technology

[0004] However, due to the wide beam angle of the light source in this backlight module, no matter how the light guide is set, some light cannot be fully reflected, resulting in light leakage; There will be an air gap between them, and the outgoing light of the light guide will be totally reflected back to the light guide by the bonding surface, so that the light incident rate will be greatly reduced, and the complete sealing of the light guide and the light guide plate will greatly increase the difficulty of assembly

Abstract

A backlight module includes a light-guiding assembly and a light source assembly. The light-guiding assembly includes a back cover, a reflector, a light-guiding plate (LGP), a number of optical correcting elements, and a frame. The light source assembly includes a main body and a light source. The back cover defines a light input area. The main body includes two reflection sides. The two reflection sides curve over the light source. The main body defines a main body opening between the two reflection sides. The light source assembly further includes a lens received in the main body opening. The light emitted from the light source and reflected by the two reflection sides are transmitted to outside of the main body through the lens.

Description

technical field [0001] The invention relates to a backlight module, in particular to a direct type backlight module and a light source module thereof. Background technique [0002] At present, the backlight modules used in displays mostly adopt edge-lit backlight modules for the sake of thinning. However, the light sources of edge-light backlight modules can only be set One side will make the border width bigger because the light source is set there. [0003] In order to make the backlight module have the characteristics of narrow frame and thinner at the same time, some existing technologies in recent years adopt the direct type backlight module, the light source is arranged under the light guide plate, and the light guide is used as the light guide element, and the light generated by the light source The light directly enters the light guide pipe, and then enters the light guide plate through the total reflection of the light guide pipe. In this way, the backlight module...
