Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. The electronic device of claim 13, wherein the touch sensor IC is configured to:
repeat application of the first self-capacitance measurement signals a specified number of times, based on the reception of the first vertical synchronization signal from the display driving IC, and apply self-capacitance measurement signals having a different combination of phases from the combination of phases of the first self-capacitance measurement signals until before receiving the second vertical synchronization signal, as at least part of the applying of the first self-capacitance measurement signals corresponding to the first combination of phases, and
repeat application of the second self-capacitance measurement signals the specified number of times, based on the reception of the second vertical synchronization signal from the display driving IC, and apply self-capacitance measurement signals having a different combination of phases from the combination of phases of the second self-capacitance measurement signals until before receiving a third vertical synchronization signal after the second vertical synchronization signal, as at least part of the applying of the second self-capacitance measurement signals corresponding to the second combination of phases.
