Abstract: Disclosed is an input-sensing part which includes first sensing electrodes each receiving a driving signal every frame, and second sensing electrodes insulated from the first sensing electrodes and extending to intersect the first sensing electrodes. A cycle of the driving signal is defined by a period of a first signal and a period of a second signal, which is a signal following the first signal and is lower in level than the first signal. A frequency of the driving signal is variable. When the frequency of the driving signal changes, the first period is fixed, and the second period changes.
