Abstract
A pixel driving circuit, a method for driving the same and a display apparatus. The pixel driving circuit includes: a light-emitting device; a driving transistor which generates a current for driving the light-emitting device to emit light according to a data voltage; a first control circuit which conducts a first electrode of the driving transistor to a first node; a second control circuit which forms a current path from the first node to a first initialization signal terminal in a case where the first control circuit conducts the first electrode of the driving transistor to the first node, to allow a threshold voltage of the driving transistor to be input to the first node; a data writing circuit which inputs the data voltage of a data signal terminal to the first node.
