1. A display device comprising:

  • a display panel including at least one electrode, the at least one electrode being an outermost electrode among a plurality of electrodes of the display panel such that the at least one electrode configured to at least one of (i) apply a common voltage to the display panel, and (ii) sense a touch on the display panel;

    a panel driving unit configured to drive the display panel based on a voltage applied to the at least one electrode;

    a power storage unit configured to store power received through the at least one electrode; and

    a switching unit configured to operatively connect the at least one electrode with at least one of the panel driving unit and the power storage unit based on an electric field around the at least one electrode,such that the switching unit operatively,connects the at least one electrode to the power storage unit, if the electric field around the at least one electrode is greater than or equal to a first electric field reference value, anddisconnects the at least one electrode from the power storage unit and connects the at least one electrode to the panel driving unit, if the electric field around the at least one electrode is less than a second electric field reference value, the second electric field reference value different from the first electric field reference value.
