Problems solved by technology

[0003] The display panel in the electroluminescent display generally has a display area and a frame area. The frame area surrounds the display area. Optical devices such as cameras can be arranged in the frame area. Due to the large volume of the camera, the area occupied by the frame area is relatively large. large, resulting in greater restrictions in achieving high screen-to-body ratio and narrow bezel design

Embodiment Construction

[0025] The specific implementation manners of a display panel and a display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The inventor found in the research that the display panel includes a plurality of pixels, and the pixels include electrically connected pixel circuits and light emitting units, such as figure 1 The schematic diagram of the structure of the pixel circuit is shown. The pixel circuit includes transistors M1-M7 and storage capacitor Cst. In order to ensure the stability of the light-emitting brightness of the light-...

Abstract

The invention discloses a display panel and a display device. The display area includes a first display area and an optical component setting area, and optical components can be arranged in corresponding positions of the optical component setting area. In this way, the problem that the optical components occupy a larger area when arranged on the frame can be avoided, so that the frame can be set narrower, and a narrow frame design can be realized. Because the areas of the first electrode and the second electrode are generally set larger, the first electrode and the second electrode are made of metal oxide materials, which can help increase the light transmittance of the first electrode and the second electrode, This enables the optical components to receive more light and improves the performance of the display device. Because the second electrode and the first grid are stacked and directly contacted, the second electrode has the same potential as the first grid, which not only realizes the function of storage capacitor, but also helps to reduce the film layer setting of the display panel. Therefore, the thickness of the display panel is reduced, and a light and thin design is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Electroluminescent display is a kind of self-luminous device, which can realize display without setting backlight. Compared with liquid crystal display, this kind of display can be made thinner and lighter because it does not need to set backlight, so it can be applied in various scenes . [0003] The display panel in the electroluminescent display generally has a display area and a frame area. The frame area surrounds the display area. Optical devices such as cameras can be arranged in the frame area. Due to the large volume of the camera, the area occupied by the frame area is relatively large. Large, resulting in greater restrictions in achieving high screen-to-body ratio and narrow bezel design. [0004] Then, how to improve the high screen-to-body ratio of the display panel and realize the narrow frame de...
