Abstract
The present disclosure relates to a pixel driving circuit, a display device and a driving method. The pixel driving circuit is configured to control on and off of a pixel unit, and includes: a first control sub-circuit, a first output sub-circuit, a second control sub-circuit, a second output sub-circuit, a third control sub-circuit, and a fourth control sub-circuit. Specifically, the fourth control sub-circuit is configured, if turned on, to cause a voltage drop of the first level signal input at the first level signal input terminal and to output the first level signal with the voltage drop to the third control node, such that a voltage at the third control node is less than or equal to a voltage at the first control node, thereby maintaining the third control sub-circuit off.
