Abstract
A pixel driving circuit is provided, including first, second, third, fourth, and fifth switching devices and first and second capacitors. The first switching device has a first terminal coupled to a first power source voltage, and a control terminal coupled to a first scan signal line. The second switching device has a first terminal coupled to a second terminal of the first switching device, a second terminal coupled to a first node and an emitting device, and a control terminal coupled to a second node. The third switching device has a first terminal coupled between the first terminal of the second switching device and a second terminal of the first switching device, a second terminal coupled to the second node, and a control terminal coupled to a second scan signal line.
