Abstract: A pixel driving circuit is provided. The pixel driving circuit includes a light emission control circuit and a drive circuit. The light emission control circuit controls a potential of a control terminal of the drive circuit under the control of a coupled signal terminal, and the drive circuit drives a coupled light-emitting element to emit light based on the potential of the control terminal thereof. The drive circuit includes two drive transistors connected in parallel, and subthreshold swings of the two drive transistors are different.
