Assignee: LG DISPLAY CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 2:
3. A touch driving circuit, comprising:
a first driving part configured to drive a plurality of touch electrode lines disposed in a first direction; and
a second driving part configured to drive a plurality of touch electrode lines disposed in a second direction different from the first direction,
wherein the first driving part outputs a touch driving signal to a first group of the plurality of touch electrode lines disposed in the first direction during a first period, the first driving part outputs a touch driving signal to a second group of the plurality of touch electrode lines disposed in the first direction during a second period, and the second driving part outputs a touch driving signal to all of the touch electrode lines disposed in the second direction in a remaining period except for the first period and the second period in a first touch sensing mode,
wherein a number of all channels driving the plurality of touch electrode lines disposed in the first direction is more than a number of channels driving the plurality of touch electrode lines disposed in the second direction,
wherein the first period and the second period are time-divided, and
wherein the first driving part does not output the touch driving signal to the second group of the plurality of touch electrode lines disposed in the first direction during the first period, the first driving part does not output the touch driving signal to the X-touch electrode lines of the first group of the plurality of X-touch electrode lines during the second period.
