Apparatus for driving of a touch panel having a dummy electrode and haptic mode

Embodiments relate to a touch panel with a haptic function and a method of operating the touch panel. The touch panel includes first electrodes and second electrodes intersecting the first electrodes. The touch panel further includes an elastic dielectric member disposed between the first electrodes and the second electrodes to separate the first electrodes and the second electrodes. The first electrodes are applied with a touch driving pulse during a sensing mode, and are applied with a voltage during a haptic mode. The second electrodes sense a touch sense signal responsive to the touch driving pulse in the sensing mode, and the second electrodes are applied with a reference voltage in the haptic mode. The elastic dielectric member vibrates in response to the voltage applied to the first electrodes in the haptic mode.
