1. A method of driving a display apparatus comprising a first sensor and a second sensor, wherein each of the first sensor and the second sensor senses at least one of at least two external signals different from each other, the method comprising:

  • applying a scan signal to charge a capacitor with a first voltage;

    charging the capacitor with a second voltage in response to a current signal corresponding to the at least two external signals sensed by at least one of the first sensor and the second sensor after applying the scan signal, wherein a level of the second voltage is greater than a level of the first voltage;

    outputting a sensing signal through a switching device in response to the second voltage;

    generating position information based on the sensing signal, wherein the position information is corresponding to a position at which the at least two external signals are sensed; and

    processing an event corresponding to the position information and displaying a processed result on a display panel.
