Problems solved by technology

[0003] In addition, in recent years, more and more functions have been gradually integrated into the display panel, such as fingerprint recognition, light-sensitive touch, face recognition or iris recognition, etc. However, in face recognition, it is necessary to use infrared light to illuminate the display Afterwards, the light beam irradiates the face and reflects, and is collected by the sensor under the screen to achieve the purpose of collecting face information; in this process, due to the infrared light irradiating the display panel, the temperature of the film layer of the display panel will be too high, which will affect the display. Normal display of the panel

Abstract

The invention discloses a display panel and a display device.The display panel is provided with a first display area and a second display area at least partially surrounding the first display area, the light transmittance of the first display area is larger than that of the second display area, and the display panel comprises a substrate; the array layer is arranged on one side of the substrate, and the array layer comprises a plurality of pixel circuits; the heat dissipation layer is arranged on the side, away from the substrate, of the array layer, the heat dissipation layer comprises a heat dissipation block at least partially arranged in the first display area, and the orthographic projection of the heat dissipation block on the substrate at least covers the orthographic projection of the corresponding pixel circuit on the substrate. Due to the fact that the heat dissipation area of the heat dissipation block is larger, the corresponding heat dissipation performance of the heat dissipation block is better, the situation that the temperature of the heat dissipation block rises due to infrared light irradiation and materials of the display panel are damaged is avoided, the service life of the display panel is prolonged, and the display effect of the display panel is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display panel and a display device. Background technique [0002] With the continuous development of display technology, consumers' requirements for display panels continue to increase, and various types of display panels have emerged and developed rapidly, such as liquid crystal display panels, organic light-emitting display panels, etc. Display technologies such as 3D display, touch display technology, curved display, ultra-high resolution display, and privacy-proof display are constantly emerging to meet the needs of consumers. [0003] In addition, in recent years, more and more functions have been gradually integrated into the display panel, such as fingerprint recognition, light-sensitive touch, face recognition or iris recognition, etc. However, in face recognition, infrared light needs to be used to illuminate the display Panel, the subsequent l...
