Abstract

The invention, which belongs to the technical field of display, discloses a method and device for aging compensation of a display panel. The display panel includes a plurality of sub pixels. The method comprises: display data of each sub pixel after first starting of the display panel are accumulated to obtain aging accumulation data of the display panel; according to a first correspondence relationship between accumulation data and aging degrees, a current aging degree corresponding to the aging accumulation data of the display panel is determined; and aging compensation is carried out on thedisplay panel based on the current aging degree. According to the invention, the current aging degree of the display panel is determined based on the obtained aging accumulation data of the display panel and the display panel is compensated based on the current aging degree, so that the illuminating efficiency of the display panel is improved. Therefore, the display panel keeps a good display effect at different aging stages.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to an aging compensation method and device for a display panel. Background technique [0002] Organic Light Emitting Diode (OLED) display panels have been widely used due to their characteristics of self-luminescence, low driving voltage, and fast response. [0003] In the related art, an OLED device in an OLED display panel generally includes: an anode, a light emitting layer and a cathode. Among them, the light-emitting layer is made of organic semiconductor materials, which can emit light under the drive of the anode and the cathode. [0004] However, as the usage time of the OLED display panel increases, the organic semiconductor material of the light-emitting layer in the OLED device will gradually age, resulting in poor display effect of the OLED display panel. Contents of the invention [0005] In order to solve the problems in related technologies, the present invention...
