摘要:
A pixel driving circuit includes 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 scan signal terminal and a data signal terminal. The compensation sub-circuit is coupled to the first node, the third node and a compensation control terminal. The adjustment sub-circuit is coupled to the second node and/or the third node, a second scan signal terminal and a first reference voltage signal terminal. The adjustment sub-circuit is configured to, in a light-emitting adjustment phase, transmit a reference voltage signal received at the first reference voltage signal terminal to the second node and/or the third node under control of a scan signal transmitted by the second scan signal terminal.
