Assignee: LG DISPLAY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. A panel driving device, comprising:
a data voltage supply circuit configured to supply a first pixel of a display panel with a first data voltage corresponding to a first gate signal and supply a second pixel of the display panel 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, the first pixel and the second pixel sharing a same data line and being sequentially scanned; 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 an on period of the third gate signal included 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.
