Problems solved by technology

In the related art, in order to improve the light transmittance of the blind hole area, the circuit wiring and film layer are usually not arranged in the blind hole area. However, there is a Newton ring phenomenon in the blind hole area, which causes the camera and other photosensitive elements in the blind hole area to take pictures. The effect is poor; or there is a problem that the display panel is difficult to process

Embodiment Construction

[0040] The display panel in the related art has the problem of the Newton ring phenomenon or the difficulty in processing the display panel. The inventors have found that the reason for this problem is that in order to improve the light transmittance of the blind hole area, usually no Circuit traces and film layers, so that the cover plate will sag towards the substrate side under atmospheric pressure, causing the distance between the cover plate and the substrate to be smaller than the wavelength of the incident light, resulting in Newton’s ring phenomenon, resulting in the camera in the blind hole area, etc. The photographic effect of the photosensitive element is poor; in related technologies, such as figure 1 As shown, by processing the groove 201 on the side of the cover plate 200 opposite to the blind hole area and facing the substrate 100, by setting the groove 201 on the cover plate 200, the gap between the cover plate 200 and the substrate 100 in the blind hole area is...

Abstract

The invention provides a display panel and a display device, relates to the technical field of display, and is used for solving the problem that a Newton ring exists in a blind hole area. The display panel is provided with a display area and the blind hole area at least partially located in the display area; the display panel comprises a substrate and a cover plate, at least one supporting piece is arranged between the substrate and the cover plate in the blind hole area, one end of the supporting piece abuts against the substrate, the other end of the supporting piece abuts against the cover plate, and the height of the supporting piece is not smaller than the distance between the substrate and the cover plate. The area of the orthographic projection of the supporting piece on the substrate is not larger than 1% of the area of the blind hole area. The display device comprises the display panel. The display panel and the display device are used for improving the Newton ring phenomenon of the blind hole area.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the rapid development of electronic equipment, full-screen display has become the development trend of electronic equipment such as mobile phones. Through the design of ultra-narrow bezel or even no bezel, the pursuit of screen-to-body ratio is ≥90%. In order to increase the screen-to-body ratio, usually on the display Blind holes are set in the area, and photosensitive elements such as cameras are placed in the blind holes to form an under-screen camera, thereby increasing the screen-to-body ratio. In the related art, in order to improve the light transmittance of the blind hole area, the circuit wiring and film layer are usually not arranged in the blind hole area. However, there is a Newton ring phenomenon in the blind hole area, which causes the camera and other photosensitive elements in the ...
