Abstract
A driving method of a display panel and a display panel are provided. Time for displaying one frame includes N times of first node potential adjustment stages, a data writing stage, and at least one first bias stress stage; the data writing stage is after the first node potential adjustment stage and before the first bias stress stage; the N times first node potential adjustment stage include N reset stages and N first adjustment voltage writing stages; and an i-th first voltage writing stage is after an i-th reset stage. In the reset stage, the first reset module is turned on to write a reset signal to the first node; in the first adjustment voltage writing phase, the first reset module is turned off, and the compensation module is turned on to write a first adjustment voltage into the first node to adjust the bias state of the driving transistor.
