Abstract: Disclosed is an organic light emitting display apparatus. The organic light emitting display apparatus outputs black gate pulses for a black image and sensing gate pulses for sensing in a vertical blank period and differently sets timings, at which the sensing gate pulses are output after the black gate pulses are output, for each gate line.
