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.

Abstract: An input sensing unit may include the following elements: a first sensing electrode including first sensors and a first connector coupling the first sensors; a second sensing electrode including second sensors and a second connector coupling the second sensors; a first sensing line including first sensing line parts and a third connector coupling the first sensing line parts; a second sensing line; and an insulating layer including a first insulating side and a second insulating side opposite the first insulating side. The first sensing line parts may overlap the first sensors and may be disposed on the first insulating side. The second sensing line may overlap the second sensors and may be disposed on the first insulating side. The first sensors may be disposed on the second insulating side. The second sensors may be disposed on the second insulating side.
