Abstract

The embodiment of the invention belongs to the technical field of display, and relates to a display panel, a preparation method thereof and a display device. The display panel comprises a substrate, a bonding pad, light-emitting unit groups, heat dissipation layers and a color conversion structure group, wherein the light-emitting unit group comprises one or more continuous light-emitting units, the light-emitting units are arranged on the bonding pad, and the bonding pad is arranged on the substrate; the color conversion structure group is arranged on the light-emitting side of the light-emitting unit, the color conversion structure group comprises one or more color conversion structures, and the color conversion structures and the light-emitting units are arranged in a one-to-one correspondence mode; and the heat dissipation layers are arranged between the light-emitting units and the color conversion structures, and the heat dissipation layers are distributed on interval areas of every two adjacent light-emitting unit groups. The display panel is provided with a heat dissipation channel, the heat dissipation layer is arranged at the end of the heat dissipation channel, and the heat dissipation channel is filled with a heat conduction material. According to the technical scheme, the heat dissipation efficiency of the display panel can be improved, and the display reliability and the display effect are improved.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] As users' requirements for colorization, high resolution, and high contrast ratio of display devices gradually increase, the fine-pitch display technology has received more and more attention. A micro-pitch display is based on an array of small inorganic semiconductor light-emitting diodes, using an LED array to make each pixel much smaller than traditional LEDs, enabling higher resolution and contrast ratios. [0003] The existing micro-pitch display can solve the colorization problem through quantum dot color conversion. This kind of quantum dot display using quantum dots as the color conversion medium generally has the advantages of high color purity, adjustable emission spectrum, controllable luminous color, good color rendering, high luminous efficiency a...
