Claim 6:
7. A touch driving device comprising:
a first touch sensing circuit configured to receive a touch sensing signal from a touch panel including a first touch panel and a second touch panel;
a plurality of second touch sensing circuits configured to receive a touch sensing signal from the second touch panel;
a plurality of first driving device pads connected to the first touch panel and selectively connected to the first touch sensing circuit; and
a plurality of second driving device pads connected to the second touch panel and selectively connected to the plurality of second touch sensing circuits,
wherein the first touch sensing circuit generates touch coordinate data using a touch sensing signal received from the first touch panel and a touch sensing signal received from the second touch panel and transmits the touch coordinate data to the second touch sensing circuit, and
the second touch sensing circuit calculates touch coordinate data generated using the touch sensing signal received from the second touch panel and the touch coordinate data transmitted from the first touch sensing circuit.
