    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.
