1. A display apparatus comprising:
a first touch sensor comprising a plurality of first driving electrodes arranged in a first area and a plurality of first sensing electrodes crossing the plurality of first driving electrodes;
a second touch sensor comprising a plurality of second driving electrodes arranged in a second area and a plurality of second sensing electrodes crossing the plurality of second driving electrodes;
a first touch integrated circuit connected to the plurality of first driving electrodes and the plurality of first sensing electrodes and configured to generate a first sensing signal;
a second touch integrated circuit connected to the plurality of second driving electrodes and the plurality of second sensing electrodes and configured to generate a second sensing signal; and
a control unit configured to select a touch area comprising a touch location from among the first area and the second area, based on the first sensing signal and the second sensing signal, and control the first touch integrated circuit and the second touch integrated circuit to sense the touch area in a first sensing mode and a remaining area in a second sensing mode.
