WIPO Patent Application WO/2020/199774
Kind Code:
A1
Abstract:
The present disclosure provides a pixel driving circuit and a driving method therefor, and a display panel. The pixel driving circuit is configured to drive a light-emitting element to emit light, and comprises: a driving sub-circuit which generates a current for causing a light-emitting element to emit light; a light-emitting control sub-circuit which is electrically connected to a first node and a second node together with the driving sub-circuit, and electrically connected to the first end of the light-emitting element; a driving control sub-circuit which is electrically connected to the driving sub-circuit and provides a data signal for the driving sub-circuit; and a reset sub-circuit which is electrically connected to a third node together with the driving sub-circuit and electrically connected to the first end of the light-emitting element, and is configured to receive a reset reference signal and under the control of the reset reference signal, reset the third node and the first end of the light-emitting element using the reset reference signal.
