According to embodiments, methods of scanning a touch panel and a touch integrated circuit (IC) for performing the same are disclosed. The touch IC simultaneously supplies a first driving signal having a first phase and a second driving signal having a second phase to a first driving line and a second driving line of the touch panel, respectively, and detects a sensing signal from a sensing line crossing the first driving line and the second driving line. The touch IC acquires a first scanning signal corresponding to the first driving line and a second scanning signal corresponding to the second driving line from the sensing signal.
