Claim 12:
13. A method for image display in the display apparatus of claim 1, comprising:
displaying an image in a respective subpixel in an image display phase;
in a sensing phase subsequent to the image display phase, the method further comprises:
providing an initial voltage signal to an anode of a respective light emitting element in the respective subpixel for a first period of time;
allowing the anode of a respective light emitting element to discharge for a second period of time, upon discontinuation of the initial voltage signal;
obtaining a residual voltage signal at the anode of the respective light emitting element at an end of the second period of time by a sensing sub-circuit of a respective pixel driving circuit; and
transmitting the residual voltage signal to an integrated circuit.
