Abstract
A display device is described including a display panel for displaying an image and an input sensing unit disposed on the display panel for sensing a user input. The input sensing unit includes: an electrode unit including first electrodes and second electrodes which intersect each other and a control unit for determining the proximity of an object or the shape of the object, based on capacitance change values of the first electrodes and the second electrodes. In a first mode the input sensing unit is driven using a self-capacitance method. The control unit may merge the capacitance change values, and determine the proximity of the object based on the merged value. In a second mode based on mutual capacitance, the control unit may determine the shape of the object.
