Description

Display panel and display device Technical Field The present application relates to the field of display technologies, and in particular, to a display panel and a display device. Background Along with the development of the market, consumers have increasingly stringent requirements on the display effect of a display screen, the comprehensive screen technology is realized, a larger screen occupation ratio is pursued through the design of ultra-narrow frames and even no frames, and under the condition that a machine body is unchanged, the display area is maximized, and the display effect is more surprise. Based on the structural design of the full screen, holes are required to be punched in the panel display area to install cameras, receivers, inductors and the like. For the display screen with the double photographing holes, however, due to the existence of the double photographing holes, the wiring corresponding to the pixel structure of the display area extends to the through hole area and then continues to extend along the edge of the through hole area, so that the wiring at the edge of the through hole area is denser. Excessive wiring causes larger edges of the through hole areas, occupies the display area of the display panel, and influences the screen occupation ratio of the display panel. Disclosure of Invention The display panel and the display device provided by the embodiment of the application can effectively reduce the area of the non-display area and improve the screen occupation ratio. In one aspect, a display panel is provided according to an embodiment of the present application, including a display area.
