Abstract:
A pixel driving circuit includes: a driving transistor, a data write circuit, a threshold compensation circuit, a first capacitor, and a second capacitor. A gate of the driving transistor is coupled to a first node, a first electrode is coupled to a second node, and a second electrode is coupled to a third node. The data write circuit is configured to transmit a signal of a data signal terminal to the second node in response to a signal of a first gate driving signal terminal. The threshold compensation circuit is configured to communicate the first node with the third node in response to a signal of a second gate driving signal terminal. The first capacitor is coupled between the first node and the first gate driving signal terminal. The second capacitor is coupled between the first node and the second gate driving signal terminal.
