Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0030] As mentioned in the background technology, the heat generated during the operation of the existing display panel cannot be effectively transferred and affects the luminous efficiency of the display panel. The accumulation of light-emitting device materials leads to thermal decomposition, resulting in attenuation of device efficiency, affecting the display effect and the life of the display device.

[0031] Based on the above technical problems, this embodiment proposes the following solutions: a display pan...

Abstract

The invention relates to a display panel and a display device. The display panel comprises a substrate; a light-emitting layer which comprises a plurality of light-emitting areas and non-light-emitting areas which are arranged at intervals; a packaging layer which is located on the side, away from the substrate, of the light-emitting layer, the packaging layer comprises a first inorganic layer andan organic layer, the first inorganic layer is located on the side, close to the substrate, of the packaging layer, and a first groove is formed in the side, away from the substrate, of the first inorganic layer; and a first heat dissipation layer, the heat conductivity coefficient of the first heat dissipation layer is larger than that of the organic layer, and the first heat dissipation layer is located in the first groove. According to the technical scheme, the heat dissipation function of the display panel is improved, damage to the light-emitting device due to accumulation of heat in thelight-emitting device is avoided, the display efficiency of the display panel is improved, meanwhile, the first heat dissipation layer is located in the first groove, it can be avoided that the thickness of the display panel is additionally increased, and the light and thin requirements are met.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display panels, and in particular, to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panel (Organic Light-Emitting Diode, OLED) device has the advantages of light weight, wide viewing angle, fast response time, etc., so it is regarded as a new generation of display technology. [0003] However, OLED light-emitting materials are susceptible to water and oxygen erosion, resulting in reduced lifespan. In the prior art, inorganic, organic, and inorganic film layers are usually stacked to package OLED devices to block water and oxygen intrusion. However, the encapsulation structure has the risk that the heat generated by the OLED device during operation cannot be effectively transferred, thereby causing thermal decomposition of the OLED device material, and reducing device efficiency and lifespan. Therefore, how to effectiv...
