Problems solved by technology

Because the backlight module 100 has an edge with a narrow frame, the light I reflected by the plastic frame 102 is easy to leak out from the gap between the plastic frame 102 and the optical film group 108 above the light guide plate 106.
If the light I is emitted by the blue light source 114, it is easy to form blue light leakage or blue halo, which will cause the problem of bluish border and affect the taste of the picture

Abstract

A backlight module comprises a light guide plate, at least one light source, an optical diaphragm group, a back board, a rubber frame and a structure. The light guide plate is provided with at least one light incident face, a light emergent face and a bottom face. Each light source is arranged on the corresponding light incident face and used for emitting a beam of blue light. The optical diaphragm group is arranged on the light emergent face of the light guide plate in a stacked manner and comprises a color conversion sheet converting blue light into white light. The rubber frame is provided with a body portion and an extension portion, wherein the body portion abuts against the back board, and the extension portion extends from the body portion to the position above the optical diaphragm group. The side, facing the light guide plate, of the extension portion is provided with a groove and a protrusion structure, wherein the groove is recessed in the direction opposite to the light guide plate, the protrusion structure protrudes towards the light guide plate, and the distance between the protrusion structure and the body portion is larger than that between the groove and the body portion. The structure is arranged on the optical diaphragm group and contained in the groove, and an interval exists between the structure and the wall surfaces of the groove. The backlight module can improve the color conversion efficiency, reduce light leak and relieve the edge bluing problem.

Description

technical field [0001] The invention relates to a backlight module. Background technique [0002] figure 1 It is a partial cross-sectional schematic diagram of a conventional backlight module. Such as figure 1 As shown, the plastic frame 102 of the backlight module 100 is limited on the backplane 104 by means of alignment and abutment. Because the backlight module 100 has an edge with a narrow frame, the light I reflected by the plastic frame 102 easily leaks out from the gap between the plastic frame 102 and the optical film set 108 above the light guide plate 106 . If the light I is emitted by the blue light source 114, it is easy to form blue light leakage or blue halo, which will cause the problem of bluish border and affect the quality of the picture. [0003] The paragraph "Background Technology" is only used to help understand the content of the present invention, so the content disclosed in the "Background Technology" paragraph may contain some prior art that is ...
