Classification: CPC G | IPC G

Claim 0:
1. An electroluminescent display apparatus, comprising:
a display panel configured to include a first pixel and a second pixel that share a same data line and are sequentially scanned;
a data voltage supply circuit configured to supply the first pixel with a first data voltage corresponding to a first gate signal and supply the second pixel with a second data voltage corresponding to a second gate signal in a vertical active period of a first frame and continuously supply the second pixel with a sensing data voltage and a recovery data voltage corresponding to a third gate signal in a vertical blank period of the first frame; and
a sensing circuit configured to sense an electrical characteristic of the second pixel on the basis of the sensing data voltage in the vertical blank period of the first frame,
wherein the recovery data voltage is for being supplied to the second pixel later than the sensing data voltage in the vertical blank period of the first frame, and
wherein a level of the recovery data voltage for being supplied to the second pixel is to change from the first data voltage to the second data voltage in the vertical blank period of the first frame.
