Display panel, aging compensation method thereof and display device
By establishing a mapping table between cumulative brightness and brightness compensation gain value in the display panel, the brightness and chromaticity of the light-emitting elements are accumulated and compensated in real time. This solves the problem of brightness reduction and image retention caused by the aging of active matrix organic light-emitting diode devices, thereby improving the display effect and panel lifespan.

Abstract
The embodiment of the present disclosure provides a display panel, comprising: a storage module configured to store a first mapping relationship table; the first mapping relationship table is a corresponding relationship table between a luminance accumulation amount of a light emitting element in the display panel and a luminance compensation gain value; an accumulation module configured to accumulate luminance data of the light emitting element in real time when the display panel is powered on to obtain a real-time accumulation amount of the luminance data; a master control module configured to find the corresponding luminance compensation gain value in the first mapping relationship table according to the real-time accumulation amount of the luminance data; calculate a real-time data signal for lighting the light emitting element according to the luminance compensation gain value corresponding to the real-time accumulation amount of the luminance data and a real-time target luminance value of the light emitting element; and light up the light emitting element in real time according to the real-time data signal for lighting the light emitting element, so that the light emitting element realizes the real-time target luminance.
