Problems solved by technology

However, full-screen applications are still difficult to achieve
[0003] In order to increase the light transmittance, the photosensitive area of ​​the under-screen camera in the display is usually designed differently from the normal display area, resulting in a large difference in the display effect between the photosensitive area and the normal display area

Embodiment Construction

[0033] 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.

[0034] As mentioned in the background, with the rapid development of information technology, people have higher and higher requirements for the design of display devices used for information interaction. Taking a mobile phone as an example, functional modules such as a front camera and a light sensor are usually arranged on the top of the display screen of the mobile phone so as to collect light from the front side of the display screen. In order to pursue the ultimate visual perception of the product, engineers c...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a substrate, a first electrode, a second electrode, a pixel definition layer and a third electrode, wherein the substrate is divided into a first display area and a second display area; the first electrode is located in the first display area on the substrate, the second electrode is locatedin the second display area on the substrate, and the light transmittance of the second electrode is larger than that of the first electrode; the pixel definition layer is located on the substrate, the pixel definition layer comprises an opening and a slope surrounding the opening, and the opening exposes the first electrode and the second electrode; the third electrode is located in the second display area and arranged on the slope surface of the pixel definition layer, and the third electrode is in lap joint with the second electrode. According to the technical scheme, the light emitting brightness of the second display area is improved, the display effect difference between the first display area and the second display area is reduced, the uniformity of the light emitting brightness andthe light color of the display panel is guaranteed, the screen-to-body ratio of the display device is improved, and implementation of full-screen display is facilitated.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, the design requirements of display screens are getting higher and higher. Structures such as the front camera and the light sensor in the display device need to collect light from the front side of the display device. Usually set at the top of the display. In order to increase the screen-to-body ratio of the display device, the design of the display screen has gradually transitioned from notch screens, water drop screens, perforated screens, etc. to full screens. However, the application of full screen display is still difficult to realize. [0003] In order to increase the light transmittance, the photosensitive area of ​​the under-screen camera in the display is usually designed differently from the normal display area, resulting in a la...
