Abstract
Embodiments of the present disclosure provide a pixel circuitry, a method for driving the pixel circuitry, an array substrate, and a display device. The pixel circuitry may include a preset circuit, a storage circuit, a driving circuit, a compensation circuit, and a light emitting element. The preset circuit may provide a signal from a data signal terminal to a first node, and provide a signal from an initialization signal terminal to a second node. The storage circuit may store a voltage difference between the first node and the second node. The driving circuit may provide a driving current to a third node according to a voltage of the first node. The compensation circuit may compensate for a voltage of the second node according to a signal from a control signal terminal. The light emitting element may emit light according to the driving current.
