Abstract

The invention discloses a display module, a preparation method thereof and a display device.A diffusion unit is arranged on the side, away from a substrate, of at least one LED chip, the diffusion unit comprises a first diffusion part and a second diffusion part penetrating through the first diffusion part, and the second diffusion part comprises a main body part and a branch part; due to the fact that the included angle between the extending direction of the branch part and the extending direction of the main body part is larger than zero, the LED chip can be arranged in the main body part, and at least part of light emitted from the position right opposite to the LED chip can be collected by the main body part and is totally reflected in the main body part and the branch part. Compared with the initial light emitted by the LED chips, the light emitted by the forking part deviates towards the direction parallel to the surface of the substrate, namely, the emergent angle of the light emitted by the LED chips is enlarged, so that the luminous intensity of the position right opposite to the LED chips is equivalent to the luminous intensity between the adjacent LED chips; therefore, the babysbreath phenomenon of uneven brightness in the display panel is weakened or eliminated, and the uniformity of the display brightness of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display module, a preparation method thereof, and a display device. Background technique [0002] With the development of display technology, a large number of Micro LEDs (Light-Emitting Diode, light-emitting diodes) or Mini LEDs have been integrated on the active addressing driving substrate as display light sources, so as to realize the individual control and lighting of each LED. , greatly improving the resolution of the displayed image. However, when a large number of Micro LEDs or Mini LEDs are currently used as display light sources, there will always be a gypsophila phenomenon with uneven brightness and darkness in the display panel. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the embodiments of the present application provide a display module, a preparation method thereof, and a display device, so as to reduce or ...
