Problems solved by technology

[0003] Mini LED is used as a backlight device, and there are gaps between the Mini LEDs. In order to cover the differences between the Mini LEDs, it is necessary to use a diffusion film and a certain mixing distance to perfectly cover them, which indirectly increases the device’s At the same time, due to the use of diffusion and other materials, the Mini LED ligh

Abstract

The invention discloses a backlight source, comprising: a substrate; a plurality of light emitting units disposed on the substrate at intervals; and a mesh member comprising a plurality of hollow structures in one-to-one correspondence to the plurality of light emitting units, wherein the plurality of hollow structures of the mesh member are arranged on the plurality of light emitting units in a sleeving manner one by one, a reflection structure is arranged on the mesh member, and the reflection structure is used for reflecting the light emitted from a side light emitting surface of each lightemitting unit, so that the reflected light is gathered in a direction perpendicular to the surface of the substrate. The backlight source disclosed by the invention can effectively utilize the lightemitted from the side light emitting surfaces of the light emitting units, thereby improving the utilization efficiency of light energy. At the same time, by adjusting the light emitting type of the light emitting units, the light mixing distances of the light emitting units can be effectively reduced, thereby reducing the thickness of the device, correspondingly reducing the light emitting halo of each light emitting unit, that is, limiting the size of a PSF curve of each light emitting unit, which is beneficial to the adjustment of a display algorithm.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a backlight source and a manufacturing method, a backlight module, a display panel, and a display device. Background technique [0002] The application of Mini LED in the field of display is a hot topic in the market in recent years. Mini LED backlight adopts array-type distribution of Mini LED to achieve high contrast effect of display technology by locally controlling the brightness of Mini LED. At the same time, Mini LED backlight , using the technology of blue light to excite quantum dots to produce white light, a wide color gamut effect is obtained, which greatly shortens the distance from OLED, so that LED can regain its advantage in comparison with OLED. [0003] Mini LED is used as a backlight device, and there are gaps between the Mini LEDs. In order to cover the differences between the Mini LEDs, it is necessary to use a diffusion film and a certain mi...
