Abstract

The embodiment of the invention provides a straight down type backlight module and a display device and relates to the technical field of display. While the backlight effect and the support supporting function are realized, the defects that the brightness value difference between a light spot central region and a support top region is larger, and the light ray uniformity of a backlight source is poorer in the prior art are overcome, and the display effect of the display device is improved. The straight down type backlight module comprises a backplate, a light source, a support, a lens and an optical module, wherein the light source is arranged on the backplate, the lens is arranged on the light source, the support is arranged on the out-light surface of the top of the lens, and the top of the support is used for supporting the optical module.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a direct-lit backlight module and a display device. Background technique [0002] With the continuous development of display technology, liquid crystal displays are more and more widely used in people's lives. The liquid crystal screen itself in the liquid crystal display does not emit light. In order to achieve the display effect, it needs to be provided with a backlight. In the prior art, the backlight of the liquid crystal screen is usually provided by the backlight module. The backlight module is divided into different types according to the light input method: Edge-lit backlight modules and direct-lit backlight modules. [0003] Such as figure 1 As shown, the direct type backlight module structure in the prior art generally includes a backplane 10 and an optical assembly 11 arranged oppositely, a bracket 12 arranged on the backplane 10, a light source 13, and a lens 14 ar...
