Abstract
In a pixel driving circuit, a compensation sub-circuit is respectively coupled to a first control terminal, a control terminal and a second terminal of the driving sub-circuit; a first terminal of the first coupling sub-circuit is coupled to the control terminal of the driving sub-circuit; a first terminal of the second coupling sub-circuit is coupled to a second terminal of the first coupling sub-circuit; a first reset sub-circuit is respectively coupled to a second control terminal, the control terminal of the driving sub-circuit and an initialization signal output terminal; a second reset sub-circuit is respectively coupled to a third control terminal, a second terminal of the first coupling sub-circuit and the first level signal output terminal; a first light emitting control sub-circuit is respectively coupled to a light emitting control terminal, a second terminal of the second coupling sub-circuit and a reference signal output terminal.
