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, its driving method and a display device. The display area includes a photosensitive device setting area. When the photosensitive device is set in the photosensitive device setting area, the problem that the photosensitive device takes up a large area when it is arranged on the frame can be avoided. , so that the bezel can be set narrower, the screen-to-body ratio can be increased, and a narrow bezel design can be realized. Moreover, when the photosensitive device is in the working state, the first structure can have the first light transmittance, so that more light can be incident into the photosensitive device through the first structure, and the performance of the photosensitive device can be improved. , and when the display panel is in the display state, if the first structure has the second light transmittance, the first structure can reduce the amount of light passing through the light-transmitting area, thereby reducing the reflection of light by the wiring in the light-transmitting area The amount, thereby improving the display contrast, improving the display effect, while improving the reliability of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, and 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 type of display can be made lighter and thinner because it does not need a backlight, so it can be used in 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, and optical devices such as cameras can be arranged in the frame area. It is too large, which leads to great restrictions when it comes to achieving a high screen-to-body ratio and a narrow bezel design. [0004] Then, how to improve the high screen ratio of the display panel and realize the narrow frame design is a technical problem to be solved urgently by those ...
