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

Claim 14:
15. A panel driving method, comprising:
supplying a first pixel of a display panel with a first data voltage corresponding to a first gate signal and supplying 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;
supplying the second pixel with a sensing data voltage corresponding to a third gate signal and sensing an electrical characteristic of the second pixel on the basis of the sensing data voltage in a vertical blank period of the first frame; and
supplying the second pixel with a recovery data voltage corresponding to a third gate signal in a vertical blank period of the first frame,
wherein the recovery data voltage is 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,
wherein the first pixel and the second pixel share a same data line and is sequentially scanned, and
wherein a level of the recovery data voltage supplied to the second pixel changes from the first data voltage to the second data voltage in the vertical blank period of the first frame.
