1. A display device comprising:
a base layer;
a light emitting element on the base layer; and
an input sensing unit configured to sense a user input,
the input sensing unit includes an electrode unit and a control unit,
wherein the electrode unit includes first electrodes arranged along a first direction and second electrodes arranged along a second direction different from the first direction,
wherein the control unit is configured to determine a proximity of an object based on self-capacitance in a first mode, to enter a second mode based on determining that the object has been proximate in the first mode, and to determine a shape of the object based on mutual capacitance in the second mode, wherein the proximity and the shape of the object are determined based on capacitance change values of the first electrodes and the second electrodes, and
wherein the control unit is configured to be operated in a different capacitance method in the first mode and the second mode.
