Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. 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,
wherein the touch sensor IC is configured to:
obtain a first vertical synchronization signal among the at least one driving signal from the display driving IC,
based on the first vertical synchronization signal being obtained, provide a plurality of first self-capacitance measurement signals having a first phase to at least some first electrodes of the plurality of electrodes with a first periodicity, and
provide a plurality of second self-capacitance measurement signals having a second phase different from the first phase to at least some second electrodes of the plurality of electrodes with the first periodicity, after providing the plurality of first self-capacitance measurement signals, and

wherein at least some of application periods of the plurality of first driving signals and the plurality of second driving signals overlap with at least part of an application period of the at least one driving signal.
