    Abstract: According to an aspect, a display device with a touch detection function includes: a scan drive unit that supplies a touch drive signal to a touch detection element in a touch detection operation period different from a display operation period in which a pixel signal and a display drive signal are sequentially supplied to display elements to perform display scanning; and a noise detector that detects noise included in a frequency component sampled by a touch detection unit. When the noise detector detects the noise, the scan drive unit changes a frequency of the touch drive signal in the touch detection operation period and supplies the changed frequency to the touch detection element.

    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.

    Abstract: A common electrode for a display, which is originally provided in a liquid crystal display element, is also used as one (drive electrode) of a pair of electrodes for a touch sensor, and the other (detection-electrode-for-the-sensor) of the pair of electrodes is newly formed. An existing common drive signal as a drive signal for display is used in common for a drive signal for the touch sensor. A capacitance is formed between the common electrode and the detection-electrode-for-the-sensor, and touch detection is performed by utilizing a change of this capacitance caused by a finger touch of a user. Thus, a display device with a touch sensor is also applicable to a mobile device in which electric potential of the user is inconstant in many cases. The newly-provided electrode is only the detection-electrode-for-the-sensor, and it is unnecessary to newly prepare a drive signal for the touch sensor.
