1. A position input system, comprising:

  • a display;

    an array of electrodes laid over the display, the array of electrodes including first electrodes disposed along a first direction and second electrodes disposed along a second direction different from the first direction and forming a transparent sensing surface; and

    a sensor controller coupled to the array of electrodes to time-divisionally control the array of electrodes in a touch sensing mode, in which the sensor controller supplies defined signals to the first electrodes and measures attributes of signals capacitively sensed by the second electrodes to detect an object positioned on the array of electrodes, and in a stylus sensing mode, in which the sensor controller measures attributes of signals sensed by the first electrodes and the second electrodes to detect a stylus positioned on the array of electrodes and in which the sensor controller decodes digital data that is encoded and transmitted from the stylus.
