Abstract
Embodiments relate to a touch panel and a method of operating the touch panel. The touch panel includes first electrodes and second electrodes separated from and intersecting the first electrodes. The first electrodes are applied with a touch driving pulse during a first sensing mode and a second sensing mode. The second electrodes sense a first touch sense signal responsive to the touch driving pulse in the first sensing mode. A subset of the second electrodes senses a second touch sense signal responsive to the touch driving pulse in the second sensing mode.
