  • Publication number: 20170147140
    Abstract: A touch panel system includes electronic pens and a touch panel. In the touch panel, a touch sensor detects a touch position that each of the electronic pens touches. A signal control device controls the touch sensor so as to transmit a reference signal indicating reference timing to the touching electronic pen, and to receive a response signal from the electronic pen. In each of the electronic pens, a reception electrode receives the reference signal from the touch panel. A timing generation circuit generates the response signal having a delay period of a predetermined value from the reference timing. A transmission electrode transmits the response signal to the touch panel through the touch sensor. The signal control device identifies the touching electronic pen, based on the delay period of the response signal received from each of electronic pens.
