Abstract
A pixel driving circuit includes: a driving sub-circuit configured to supply a driving signal to an element to be driven; a detection sub-circuit electrically connected to a detection control signal terminal and a detection node and configured to detect a voltage value of the detection node in response to a detection control signal received at the detection control signal terminal. The detection node is equivalent to a point on a connection line between the driving sub-circuit and the element to be driven.
