Abstract
A display panel comprises a reset module, a data-writing module, a driving transistor, a light-emitting control module, a first memory module and a first signal module. The reset module is configured to provide a reset signal to an anode of a light-emitting element through a light-emitting control module. The first signal module is configured to provide a data voltage signal to the data-writing module in a data-writing stage to write the data voltage signal to a gate electrode of the driving transistor and a first end of the first memory module through the data-writing module and provide a data current signal to the driving transistor in the data-writing stage to compensate a threshold voltage of the driving transistor to the second node. The light-emitting control module controls a driving current generated by the driving transistor to flow into a light-emitting element to drive the light-emitting element to emit light.
