PIXEL CIRCUIT, DISPLAY PANEL, DISPLAY DEVICE, AND DRIVING METHOD

Document Type and Number:

WIPO Patent Application WO/2018/045749

Kind Code:

A1

Abstract:

A pixel circuit, a display panel, a display device, and a driving method. The pixel circuit (100) comprises: a storage capacitor comprising a first end and a second end, the first end being connected to a first node, and the second end being connected to a reference voltage line to receive a reference voltage; an organic light-emitting diode; a driver transistor comprising a gate connected to the first node, wherein the driver transistor is configured to control the organic light-emitting diode to emit light according to the voltage of the first node; a first reset circuit (110) configured to provide an initial voltage to the first node in response to a reset signal; a scanning circuit (140) configured to provide a data signal to a third node in response to a scanning signal; a compensating circuit (120) configured to provide a compensating voltage to the first node in response to the scanning signal; and a light emission control circuit (150) configured to control the organic light-emitting diode to emit light in response to a light emission control signal.
