Abstract: A touch panel includes touch electrodes and a touch driver configured to apply a driving signal to the touch electrodes to form sensing capacitors comprising the touch electrodes, the touch driver configured to sense a change in an amount of charge caused by the sensing capacitors. The touch driver is configured to distinguish hovering and floating based upon a result of sensing the time change in an amount of charge. The touch driver is configured to apply a highest level of the driving signal to a hovering electrode corresponding to a hovering position from among the touch electrodes.
