Abstract
Provided is a display panel. The display panel includes a substrate, a plurality of sub-pixels and at least one multivoltage supply circuit; where each of the plurality of sub-pixels includes a pixel circuit and a light-emitting element; and the pixel circuit includes an initialization circuit, a data writing circuit, a drive circuit, a threshold compensation circuit, a first light-emission control circuit and a storage circuit; where the first light-emission control circuit controls the drive circuit to generate a drive current which flows into the light-emitting element in a light emission stage; and the at least one multivoltage supply circuit supplies a reset signal to a first terminal of the storage circuit in the initialization stage and a first stage and supplies a first power signal to the first terminal of the storage circuit in a second stage.
