1. An electronic device comprising:
a loop coil;
a display unit configured to include a plurality of pixels;
a display driver configured to apply a data signal and a scan signal to the pixels based on a vertical synchronization signal and a horizontal synchronization signal;
a plurality of touch electrodes positioned on the display unit;
a driving receiver configured to apply a driving signal to the loop coil during a first period and to receive a sensing signal from at least one of the touch electrodes during a second period after the first period; and
a controller configured to generate touch information by using the sensing signal received during a sensing period and determine a period excluding a period during which a scan signal applied to one pixel among the pixels is at an enable level as the sensing period,
wherein the driving signal is synchronized to at least one pulse of the vertical synchronization signal and the horizontal synchronization signal.
