Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate, a heat dissipation structure layer, a binding substrate and an adhesive layer. According to the display panel provided by the invention, the heat dissipation structure layer is added between the array substrate and the binding substrate. The heat dissipation structure layer absorbs and dissipates heat released by the array substrate so as to prevent devices in the display panel from losing efficacy due to heating. Moreover, heat dissipation grooves are formed in the heat dissipation structure layer, on one hand, the heat dissipation grooves can increase the heat dissipation area and improve the heat dissipation efficiency, and on the other hand, the heat dissipation grooves can serve as flow guide plates to dissipate heat out of the display panel in a hot air flow mode.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device thereof. Background technique [0002] During the research and practice of the prior art, the inventors of the present application found that, for light-emitting diode (Light Emitting Diode, LED) chips, if the heat dissipation is not sufficient, it will cause non-uniform distribution of thermal stress and reduce the luminous efficiency of the chip. And phosphor lasing efficiency drops. Studies have shown that when the temperature exceeds a certain value, the failure rate of the device will climb exponentially. [0003] Therefore, it is particularly important to dissipate heat from the LED chip to avoid device failure. Contents of the invention [0004] The present application provides a display panel and a display device, which can dissipate heat from the display panel and avoid device failure caused by heat. [0005] The appli...
