Abstract:
An electronic device according to an embodiment comprises: a display; a display-driving integrated circuit (IC) set to apply one or more driving signals to the display; a touch sensor including a plurality of electrodes; and a touch sensor IC configured to check an input position on the touch sensor, wherein the touch sensor IC is configured to: acquire, from the display-driving IC, a first vertical synchronization signal from among the one or more driving signals, provide a plurality of first measurement signals corresponding to a first phase at intervals of a first duration to at least a first portion of electrodes among the plurality of electrodes based on the acquisition of the first vertical synchronization signal, and, after providing the plurality of first measurement signals, provide a plurality of second measurement signals corresponding to a second phase, different from the first phase, at intervals of the first duration to at least a second portion of electrodes among the plurality of electrodes, wherein at least a portion of the application period of the plurality of first driving signals and the plurality of second driving signals can overlap with at least a portion of the application period of the one or more driving signals.
