    Abstract: A sensor-integrated display panel including an operation surface for performing an input operation and an image display surface which are formed integrally with a sensor as one piece. A data transfer device supplies the sensor-integrated display panel with a drive signal for driving the sensor and outputs sensing data corresponding to a potential of a sensor signal output from the sensor. A contact electrode is provided in a frame formed around the sensor-integrated display panel to vary the potential of the sensor signal when a conductor touches or does not touch to the frame. An application executing device receives and analyzes the sensing data and generates a signal to select an operating function in accordance with an analysis result.
