Abstract
Embodiments of the present disclosure provide a pixel circuitry and a driving method thereof. In the pixel circuitry, the reset circuit provides an initialization signal to a first node and one end of the light emitting device based on a reset signal. The driving transistor provides a driving current based on the voltage of the first node. The data signal write circuit provides a data signal to a third node based on a strobe signal. The compensation circuit couples a second node to the first node based on the strobe signal. The voltage supply circuit provides a first voltage signal to the second node based on a control signal. The control circuit provides a driving current provided by the driving transistor to the light emitting device based on the control signal. The light emitting device emits light according to the driving current.
