Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises a first insulating layer located on a substrate, a barricade layer located on the side, awayfrom the substrate, of the first insulating layer, a metal reflection layer, micro light emitting diodes located in separation-levee open structures respectively and a metal heat-dissipating layer connected with the metal reflection layer, wherein the barricade layer comprises the multiple separation-levee open structures, the metal reflection layer comprises multiple metal reflection structures corresponding to the separation-levee open structures in a one-to-one mode, and the micro light emitting diodes are arranged to be insulated from the metal reflection structures. According to the display panel and the display device, due to the fact that heat on the metal reflection layer can be conducted to the metal heat-dissipating layer and dissipated through the metal heat-dissipating layer, and that is to say, cooling can be conducted on the micro light emitting diodes by the metal heat-dissipating layer to reduce the temperature differences of the micro light emitting diodes in the different positions, the luminescent performance of the micro light emitting diodes in the different positions is almost the same, and then the evenness of the lightness of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In the micro light-emitting display panel, the micro light-emitting diodes will generate heat during operation, and when the micro light-emitting display panel displays images, the brightness of the micro light-emitting diodes at different positions may be different, wherein the micro light-emitting diodes with higher brightness The more heat generated, the temperature of the micro-LEDs at different positions is different. Since the luminous performance of the micro-LEDs is greatly affected by the temperature, when the temperatures of the micro-LEDs at different positions are different, the temperature of the micro-LEDs at different positions is different. The luminous properties of the micro light emitting diodes on the micro light emitting diodes are different, which makes the brightness uniformity of ...
