Abstract
A compensation method for a display panel and a display device are provided. The display panel includes a plurality of sub-pixels, and at least one of the plurality of sub-pixels includes a sensing capacitor. The method includes: obtaining a first voltage value and a second voltage value of the sensing capacitor, obtaining a temperature change amount of a sub-pixel corresponding to the sensing capacitor according to the first voltage value and the second voltage value of the sensing capacitor, determining a value of a compensation parameter of the sub-pixel according to the temperature change amount of the sub-pixel and a preset correspondence between the temperature change amount of the sub-pixel and the compensation parameter; and performing a compensation on a driving voltage of the sub-pixel according to the value of the compensation parameter as determined.
