Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a substrate layer, a light source layer and a light mixing layer, wherein the light source layer is arranged on a substrate, and comprises a plurality of mini LEDs (Light Emitting Diodes) distributed in an array; the light mixing layer is arranged on one side of the light source layer far away from thesubstrate layer, and comprises a first light mixing layer; the first light mixing layer comprises a plurality of light mixing structures; each mini LED corresponds to a plurality of light mixing structures; the light mixing structure comprises a first surface close to one side of the light source layer and a second surface far away from one side of the light source layer; and the first surface protrudes toward a direction far away from the light source layer, and / or the second surface protrudes toward a direction close to the light source layer in the light mixing structure. According to thebacklight module and the display device, the uniformity of the brightness of the whole surface of the backlight can be improved, thereby improving the problem that the backlight module is filled withstark.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a backlight module and a display device. Background technique [0002] Mini LED (mini Light Emitting Diode, mini light-emitting diode, ie mini LED) is a small-sized LED. In recent years, it has been actively developed by major manufacturers because it can realize the local backlight driving function and has the advantages of high contrast and high brightness. The mini LED can be used as a surface light source in the backlight module without the need for structures such as light guide plates and reflectors, which is conducive to reducing the thickness of the backlight module. [0003] When mini LEDs are used as surface light sources, there will be gaps between adjacent mini LEDs due to the limitation of manufacturing cost and process. When the mini LED emits light, the front side of the mini LED has a strong light intensity, showing a bright area, while the gap...
