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

Abstract

The invention discloses a display panel, a driving method thereof and a display device. The display area comprises the photosensitive device setting area, and when a photosensitive device is arrangedin the photosensitive device setting area, the problem that the occupied area is large when the photosensitive device is arranged on a frame can be avoided, so that the frame can be arranged narrower,the screen-to-body ratio is increased, and the design of a narrow frame is realized. Moreover, when the photosensitive device is in a working state; therefore, a first structure has the first light transmittance; more light can be incident into the photosensitive device through the first structure, the performance of photosensitive device is improved, when the photosensitive device is in a non-working state and the display panel is in the display state, if the first structure has the second light transmittance, the amount of light penetrating through a light-transmitting area can be reduced through the first structure, and then the amount of light reflection of wires located in the light-transmitting area is reduced, so that the display contrast ratio is raised, the display effect is improved, and meanwhile, the reliability of the display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a driving method thereof 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...
