  • Patent number: 11189228
    Abstract: A pixel circuit, a method for driving a pixel circuit, and a display device are provided. The pixel circuit includes: a storage circuit, a data writing circuit, a light emitting driving circuit, and a compensation circuit. The data writing circuit is configured to write a data voltage to the storage circuit under control of a scanning control signal; the storage circuit is configured to store the data voltage and enable a stored data voltage to be available to the compensation circuit for a compensation operation; the compensation circuit is configured to maintain a compensation voltage based on the stored data voltage at a control terminal of the light emitting driving circuit under control of a compensation control signal; and the light emitting driving circuit configured to drive the light emitting element to emit light under control of the compensation voltage.
