Problems solved by technology

[0002] As the display panel is used longer, the performance of the internal materials will gradually deteriorate, resulting in abnormal phenomena such as reduced display brightness and uneven display, which will affect the display performance of the display panel.
[0003] Therefore, the existing display panels have the problems of brightness attenuation and poor brightness uniformity after long-term use, which need to be improved.

Abstract

The invention provides a display panel, and the display panel comprises a pixel definition layer which comprises light-emitting openings distributed in an array; the light-emitting layer is arranged in the light-emitting opening; and the photosensitive element is arranged on the pixel definition layer, and the projection of the photosensitive element on the pixel definition layer is located outside the light-emitting opening. According to the display panel, the light sensing element is arranged above the light emitting opening of the display panel, the light sensing element can better sense the light rays emitted upwards by the light emitting layer, and the light signals are converted into the electric signals to be fed back, so that the light emitting brightness of the display panel is compensated; the problems of brightness attenuation and poor brightness uniformity after long-time use of an existing display panel are solved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel. Background technique [0002] As the use of the display panel increases, the performance of the internal materials will gradually deteriorate, which will lead to abnormal phenomena such as reduced display brightness and uneven display, and even affect the display performance of the display panel. [0003] Therefore, the existing display panels have the problems of luminance attenuation and poor luminance uniformity after long-term use, which need to be improved. Contents of the invention [0004] The invention provides a display panel to improve display brightness and brightness uniformity of the display panel. [0005] In order to solve the above problems, the technical scheme provided by the invention is as follows: [0006] The present invention provides a display panel, which includes: [0007] A pixel definition layer, including light-emitting openings dis...
