Display panel, driving method and display device

Abstract

The invention discloses a display panel, a driving method and a display device. The display panel comprises a substrate body, a plurality of sub-pixels and at least one hopping signal providing module. Each sub-pixel comprises a pixel circuit and a light-emitting element; the pixel circuit comprises an initialization module, a data writing module, a driving module, a threshold compensation module,a first light-emitting control module and a storage module. The initialization module provides initialization signals for the control end of the driving module and the anode of the light-emitting element in the initialization stage; the data write-in module transmits a data signal to the control end of the driving module in a data write-in stage; the threshold compensation module compensates thethreshold voltage of the driving module to the control end of the driving module; the first light-emitting control module controls the driving module to generate driving current to flow into the light-emitting element in the light-emitting stage; the jump signal providing module provides a reset signal to the first end of the storage module in an initialization phase and a first phase, and provides a first power supply signal to the first end of the storage module in a second phase.
