Abstract
A pixel driving circuit includes: a first transistor; a writing sub-circuit configured to write a voltage of a first data voltage terminal into a first terminal of the first transistor in response to a signal of a first control signal terminal; a first compensation sub-circuit configured to couple a voltage of a second terminal of the first transistor to a control terminal of the first transistor and store a voltage of the control terminal in response to the signal of the first control signal terminal; a second compensation sub-circuit configured to couple a voltage of a second data voltage terminal to the control terminal of the first transistor in response to a signal of a second control signal terminal; and a light-emitting control sub-circuit configured to be controlled to form a current path between first and second voltage terminals in response to a signal of the third control signal terminal.
