Abstract

The invention discloses a display panel and a preparation method thereof. The display panel comprises a substrate, an anode layer, a light-emitting heat dissipation structure, a cathode layer and a cover plate; the light-emitting heat dissipation structure comprises a light-emitting layer and a heat dissipation layer; and the heat dissipation layer is located between the light-emitting layer and the cathode layer or the anode layer. The heat dissipation layer can reasonably and effectively dissipate heat generated in the light-emitting process, the light-emitting layer is protected, and the light-emitting effect of the display panel is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a preparation method thereof. Background technique [0002] In the working process of the OLED device, the electrodes are energized to form carriers, and the carriers move and jump to the light-emitting layer to recombine to generate excitons, and the excitons excite the light-emitting materials to emit light. [0003] like figure 1 As shown, a common OLED device structure is a substrate 100 , an anode layer 200 , a pixel definition layer 300 , a first auxiliary transport layer 400 , a light emitting layer 500 , a second auxiliary transport layer 600 , a cathode layer 700 and a cover plate 800 . [0004] During the process of emitting light, the OLED device will generate heat, which has a significant impact on the life and performance of the OLED device. Therefore, a reasonable structure is required to realize the heat barrier or rapid dissipation of the OLED de...
