Driving method and driving control method for pixel circuit
There is provided a driving method for a pixel circuit including a driving transistor, a data writing circuit, a sensing circuit, and a storage capacitor. The driving method includes: during a sensing write stage, writing a test voltage equal to a sum of a first reference voltage and a threshold voltage of the driving transistor, by the data writing circuit, to the control electrode of the driving transistor, and writing a second reference voltage, by the sensing circuit, to a second electrode of the driving transistor; during a sensing sampling stage, continuing to write the test voltage to the control electrode of the driving transistor by the data writing circuit, and stopping writing a voltage to the second electrode of the driving transistor by the sensing circuit. The driving method further includes a sensing reset stage and a sensing charging stage.
