Abstract

A method for image display in a display apparatus is provided. The method includes 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 includes 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.
