Abstract
A pixel circuit and a driving method therefor and a display panel are provided. The pixel circuit includes a driving circuit, a data writing circuit, a storage circuit, and a first reset circuit; the driving circuit includes a control terminal, a first terminal, and a second terminal, and is configured to control a driving current flowing through the first terminal and the second terminal for driving a light-emitting element to emit light; the data write circuit is configured to write a data signal into the control terminal of the driving circuit; the storage circuit is configured to store the data signal; the first reset circuit is configured to apply a first initialization voltage to the control terminal of the driving circuit; the driving circuit and the data write circuit each include an N-type thin film transistor; and the first reset circuit includes an N-type oxide thin film transistor.
