Abstract:
A display panel and a method for driving the same, and a display device are provided. The display panel includes a light emitting element and a pixel circuit that includes a data writing module configured to provide a data signal and an adjusting voltage, a driving module configured to provide a driving current to the light emitting element and including a driving transistor, and a compensation module configured to compensate a threshold voltage of the driving transistor. An operation process of the display panel includes a period of a data writing frame during which the pixel circuit executes a data writing phase during which the data writing module writes the data signal and a light emitting phase, and a period of a holding frame during which the pixel circuit executes a reset and adjustment phase during which the data writing module writes the adjusting voltage and the light emitting phase.
