Abstract

Embodiments of the present application disclose a display panel and a display device. The display panel includes a panel body and a heat dissipation layer. The panel body includes a first body part, the heat dissipation layer is located on one side of the panel body, the heat dissipation layer includes a first heat dissipation part corresponding to the first body part, and the first heat dissipation part is far away from the The surface of one side of the panel body is an uneven surface, so as to increase the surface area of ​​the first heat dissipation part, thereby increasing the contact area between the heat dissipation layer and the outside world, so that the heat generated in the display panel can be reduced. The first heat dissipation portion conducts the heat to the outside of the display panel faster, which is beneficial to improve the problem of poor heat dissipation in the first main body portion of the display panel, and can avoid the problem of abnormal display of the display panel caused by poor heat dissipation.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] In order to avoid the interference of electromagnetic, heat and other factors on the display panel, a heat dissipation layer will be arranged on the back of the display panel to realize functions such as force buffer protection, electromagnetic shielding, and heat dissipation. In the heat dissipation layer, the copper foil for shielding and heat dissipation is located at the outermost side, and the heat released by the driver chip and circuit board of the display panel needs to be transferred to the copper foil through the multi-layer film in the heat dissipation layer. Therefore, if the material of the heat dissipation layer is improperly selected and the adhesion between the heat dissipation layer and the display panel is not good, it will lead to uneven heat conduction, which will cause concent...
