Abstract

The invention provides a direct type backlight module and a display device. The direct type backlight module includes a light distribution board, a reflective sheet forming a cavity with the light distribution board, and a backlight source positioned in the cavity; the light distribution board includes reflective regions and light-transmitting regions except for the reflective regions; and the reflective regions have reflective materials. The direct type backlight module and the display device can evenly emit light from a light-going surface, the strength of the light distribution board is high, the reflective materials can be arranged on the light distribution board, the technical process is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a direct-lit backlight module and a display device. Background technique [0002] In recent years, the technology of liquid crystal display devices has become more and more mature, and its application has become more and more extensive. As consumers' preferences and requirements increase, thinner display devices are more likely to be favored by consumers. [0003] In order to achieve the purpose of thinning the display device, it may be considered to reduce the thickness of each component of the display device, for example, the display panel, the optical film, and the backlight module may be respectively thinned. Among them, since the thickness of the backlight module accounts for a relatively large proportion of the thickness of the display panel, the backlight module becomes the main target for thinning the display device. [0004] The backlight module can be divided ...
