PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREOF, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2024/000547
Kind Code:
A1
Abstract:
Disclosed is a pixel driving circuit, comprising a driving sub-circuit, a writing sub-circuit, a compensation sub-circuit, and an adjustment sub-circuit. The driving sub-circuit is coupled to a first node, a second node, and a third node. The writing sub-circuit is coupled to the second node, a first scanning signal end, and a data signal end. The compensation sub-circuit is coupled to the first node, the third node, and a compensation control end. The adjustment sub-circuit is coupled to the second node and/or the third node, a second scanning signal end, and a first reference voltage signal end, and the adjustment sub-circuit is configured to transmit, in a light-emitting adjustment stage, a reference voltage signal received at the first reference voltage signal end to the second node and/or the third node under the control of a scanning signal transmitted from the second scanning signal end.
