Problems solved by technology
However, at present, the external quantum efficiency of Micro-LED is generally 20%-30%, the luminous efficiency is not high, and the remaining 70%-80% is converted into heat
Moreover, the size of the Micro LED device is very small, and the heat generated is difficult to dissipate, resulting in an increase in the junction temperature of the LED, resulting in a decrease in the light efficiency of the LED, and color shift. At the same time, more energy will be converted into heat, which will aggravate the deterioration of the LED.

The invention provides a display panel and a display device.The display panel comprises a display area and a non-display area, the display area is adjacent to the non-display area, the display panel further comprises an insulating heat conduction film, a pixel light-emitting unit and a heat dissipation structure formed by multiple film layer protrusions, the heat dissipation structure is formed in the non-display area, the insulating heat-conducting film and the pixel light-emitting unit are formed in the display area, the insulating heat-conducting film surrounds the periphery of the pixel light-emitting unit, and at least part of the insulating heat-conducting film is connected with the heat dissipation structure so as to conduct heat generated by the pixel light-emitting unit to the heat dissipation structure. According to the display panel, the insulating heat conducting film is arranged in the display area and the heat dissipation structure formed by the multiple film layer protrusions is arranged in the non-display area, so that the insulating heat conduction film can transmit heat generated by the pixel light-emitting units to the heat dissipation structure of the non-display area for heat dissipation, the heat dissipation area of the display panel is effectively increased, the heat dissipation effect is improved, and the problems of light effect reduction, color cast and the like of the display panel are avoided.
Description
technical field [0001] The present application relates to the display field, and in particular to a display panel and a display device. Background technique [0002] Micro-LED has the advantages of light and thin, long life, low power consumption, etc. It is a new generation of display technology equipment. However, at present, the external quantum efficiency of Micro-LED is generally 20%-30%, the luminous efficiency is not high, and the remaining 70%-80% is converted into heat. Moreover, the size of the Micro LED device is very small, and the heat generated is difficult to dissipate, resulting in an increase in the LED junction temperature, resulting in a decrease in LED light efficiency and color shift. At the same time, more energy will be converted into heat, which will aggravate the deterioration of the LED. Contents of the invention [0003] In view of this, the present application provides a display panel and a display device. [0004] The display panel according ...
