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...
