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 an array substrate 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 inventors found in research that the display panel includes a display area, the display area includes a photosensitive device setting area and a conventional display area, and the conventional display area at least partially surrounds the photosensitive device setting area, a plurality of pixels are arranged in the display area, and the photosensitive device setting area There is a light-transmitting area...

Abstract

The invention discloses an array substrate and a display device. The display area comprises a photosensitive device arranging area. When a photosensitive device is arranged in the photosensitive device arranging area, the problem of large occupied area when the photosensitive device is arranged on the frame can be avoided so that the frame can be set narrower, the screen proportion is increased and the design of the narrow frame can be realized. Moreover, the first structure is located in the light transmitting region, the second structure is located in the region where the pixel is located, and the light transmittance of the first structure is greater than that of the second structure so that the light transmitting region is ensured to have a higher light transmittance, the photosensitivedevice can receive more light, the performance of the photosensitive device can be improved and the performance of the display device can be improved. In addition, the difference between the first distance and the second distance is less than a preset threshold value, the functional layer is ensured to have better flatness and thus the influence on the performance of the array substrate due to segment difference can be avoided and the reliability of the display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] An electroluminescent display is a self-luminous device that can display without a backlight. Compared with a liquid crystal display, this kind of display can be made thinner and thinner because it does not need a backlight, so it can be applied to various scenarios. [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 design is a technical ...
