1. A display device, comprising:

  • a first surface;

    a sensing capacitor having a sensing input electrode and a sensing output electrode, wherein the sensing capacitor stores a first amount of charges and the sensing capacitor stored a second amount of charges when an external object contacts on the first surface;

    a sensing input signal line electrically connected with the sensing input electrode and receiving a sensing input signal to charge the sensing capacitor to the first amount of charges;

    a sensing output signal line electrically connected with the sensing output electrode; and

    a sensing signal processor connected with the sensing output signal line, wherein the sensing signal processor determines whether an external object contacts on the first surface based on a voltage difference between the first amount of charges and the second amount of charges stored in the sensing capacitor.
