    Abstract: An electronic device which includes a display layer that operates in a folded state or an unfolded state and has an active region including a folding region and a plurality of non-folding regions, a sensor layer, and a sensor driver that operates in a charging drive mode to transmit a charging signal to the sensor layer. The sensor layer includes a plurality of first electrodes, a plurality of second electrodes, a plurality of first auxiliary electrodes, and a plurality of second auxiliary electrodes. The sensor driver sequentially provides the charging signal to the plurality of first auxiliary electrodes in a first direction during the charging drive mode, and the number of times that the charging signal is provided in the folded state and the number of times that the charging signal is provided in the unfolded state are different from each other.

    Abstract: A driving method of a touch sensing part includes sensing a touch of a user by comparing a capacitance formed by a first sensing electrode and a second sensing electrode crossing the first sensing electrode with a reference value in a reference touch mode, varying the reference value such that the reference value decreases along a decrease in the capacitance, during a first period, when an ambient temperature is lower than a reference temperature, sensing the user's touch by comparing the reference value and the capacitance, with the reference value maintained uniformly, during a second period following the first period, when the touch of the user is made, and varying the reference value such that the reference value decreases, during a third period following the second period.
