Abstract

The embodiment of the invention provides a backlight module, a preparation method of the backlight module and a display device, and the backlight module comprises a plurality of mini-LED chips which are arranged at intervals; the packaging adhesive layer is arranged on all the mini-LED chips, and the space between every two adjacent mini-LED chips is filled with the packaging adhesive layer; the light absorption layer is arranged on the side, away from the mini-LED chips, of the packaging adhesive layer, a plurality of through holes are formed in the light absorption layer, and the through holes correspond to the mini-LED chips one to one; and the quantum dots are arranged in at least one through hole. The quantum dots are arranged on the side, deviating from the mini-LED chip, of the packaging adhesive layer, the scheme that the quantum dots are arranged on the color film substrate and then attached to the array substrate in a paired mode is replaced, the gap between the two substrates can be eliminated, the distance between the quantum dots and the mini-LED chip is reduced, and the yield of the LED is improved. And the problem of light crosstalk caused by a large gap between the two substrates between the adjacent mini-LED chips is further reduced.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a backlight module, a manufacturing method thereof, and a display device. Background technique [0002] For a liquid crystal display device, a backlight module is usually required to provide a backlight source. Due to the outstanding advantages of mini-LED chips in display, performance, cost, etc., in some display devices, mini-LED chips are usually used as backlight sources. [0003] Wherein, in order to realize a wider color gamut display, QDs (Quantum Dots, quantum dots) are applied in a display device. In current display devices, quantum dots are usually arranged on a color filter substrate, and mini-LED chips are arranged on an array substrate. The color filter substrate and the array substrate need to be precisely aligned and bonded to realize a complete device. However, the gap between two substrates is usually large, which is prone to the problem ...
