Abstract:
This application discloses a display panel including pixel circuits and light-emitting elements, wherein a first pixel circuit includes a first reset module that is connected to a first light-emitting element and provides a first reset signal to the first light-emitting element under a condition that the first reset module is turned on; a second pixel circuit includes a second reset module that is connected to a second light-emitting element and provides a second reset signal to the second light-emitting element under a condition that the second reset module is turned on; a data writing period of the pixel circuits includes a data writing phase and one or more holding phases; at least one holding phase includes a first reset sub-phase in which the first and second reset modules are turned on, voltages of the first and second reset signals are Vref21 and Vref22 respectively, and Vref21≠Vref22.
