Abstract:
A pixel driving circuit and a method for controlling the same, and a display apparatus are provided. The pixel driving circuit includes a charge storage circuit, a driving circuit and first to third switching circuits. The first switching circuit includes first to third switching elements. Control electrodes of the first and third switching elements are coupled to a reset signal terminal. First electrode of the third switching element is coupled to a fourth node. Second electrode of the second switching element is coupled to a third node. The charge storage circuit includes capacitors coupled in parallel or in series. The first switching circuit is turned on in a first phase and turned off in second and third phases. The second switching circuit is turned off in the first and second phases and turned on in the third phase.
