Classification: CPC G | IPC G

Claim 11:
12. An electronic device comprising:
a display;
a display driving integrated circuit (IC) configured to apply at least one driving signal to the display;
a touch sensor including a plurality of electrodes; and
a touch sensor IC configured to identify an input position on the touch sensor screen panel,
wherein the touch sensor IC is configured to:
measure first self-capacitance of each of at least some of the plurality of electrodes by applying first self-capacitance measurement signals having a first combination of phases to the at least some of the plurality of electrodes, and
measure second self-capacitance of each of at least some of the plurality of electrodes by applying second self-capacitance measurement signals having a second combination of phases to the at least some of the plurality of electrodes, after the first self-capacitance is measured by applying the first signals.
