Abstract

The invention provides a backlight module. The backlight module includes a substrate, a diffuser plate, light sources, optical lenses and transparent supporting components, wherein the light sources are arranged on the substrate, the optical lenses cover the light sources, and the transparent supporting components are arranged on the optical lenses and used for supporting the diffuser plate. According to the backlight module, the transparent supporting components are arranged on the optical lenses, and cannot block light rays, and thus a shadow cannot be formed on the diffuser plate, and the technical problem that an existing backlight module has a supporting column to block the light to produce a shadow is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module. Background technique [0002] Such as figure 1 As shown, in the existing direct-lit LED backlight module, support columns 12 are provided on the substrate 11 to support the diffuser plate 13 and prevent the diffuser plate 13 from being deformed due to thermal expansion and contraction and vibration during transportation. [0003] However, the support column 12 blocks the light from the light source (LED lamp) 14 , thereby forming a dark shadow on the diffuser plate 13 . [0004] Therefore, the existing backlight module has the technical problem that the supporting pillars block the light and produce dark shadows. Contents of the invention [0005] The invention provides a backlight module to solve the technical problem in the existing backlight module that a supporting column blocks light and produces dark shadows. [0006] In order to solve the above pr...
