1. A method of controlling a position input system which includes an array of electrodes, the method comprising:
time-divisionally controlling the array of electrodes in a touch sensing mode and in a stylus sensing mode,
in the touch sensing mode, supplying defined signals to the array of electrodes and measuring attributes of signals capacitively sensed by the array of electrodes to detect an object positioned on the array of electrodes, and
in the stylus sensing mode, controlling the array of electrodes to selectively form loop electrodes in which signals are electromagnetically induced by stylus signals transmitted from a stylus and measuring attributes of the electromagnetically induced signals to detect the stylus positioned on the array of electrodes.
