  • Patent number: 11354004
    Abstract: A display device according to the present disclosure includes a panel unit including common electrodes for common use in image display and touch detection, a drive circuit configured to output a touch drive signal to each of the common electrodes, and a touch detection circuit configured to detect touch of an object onto the panel unit based on a detection signal received from each of the common electrodes. In a unit frame period, display periods and touch detection periods each including first and second sections are alternately placed. In the touch drive signal in each touch detection period, amplitude values of pulses included in the first section change from a first value to a second value larger than the first value, across the first section, and amplitude values of pulses included in the second section change from the second value to the first value across the second section.

  • Publication number: 20220155938
    Abstract: A display device includes a plurality of common electrodes. A second drive circuit supplies a touch drive signal to each of the plurality of common electrodes. A touch detection circuit performs detection of a touch by an object to the display device, based on a touch detection signal received from each of the plurality of common electrodes in one or more touch detection periods. A length of the one or more touch detection periods is a detection time. The touch detection circuit detects a noise at a frequency of the touch drive signal based on the touch detection signal. When the noise is detected, the control circuit changes the frequency of the touch drive signal to be lower than the frequency used when the noise is not detected and changes the detection time to be longer than the detection time used when the noise is not detected.

  • Publication number: 20220027006
    Abstract: A display device includes multiple common electrodes. A drive circuit supplies a reference voltage for image display during a display period, for which the display device displays an image, and supplies a touch drive signal during a touch detection period, to each of the multiple common electrodes. A touch detection circuit performs detection of a touch by an object on the display device, during a touch detection period. A selector selects, as an operation mode of the display system, a first mode or a second mode. The first mode is an operation mode in which the display period and the touch detection period are alternately arranged within each of multiple successive frame periods of the display device. The second mode is an operation mode in which, during at least one frame period, the display device displays an image while the touch detection circuit stops touch detection.

  • Publication number: 20210342054
    Abstract: In a display system, a source drive circuit outputs a source signal. Multiple switching elements are respectively connected between multiple source lines and the source drive circuit, and each switching element outputs a source signal output from the source drive circuit to a source line in an ON state and stops the output of the source signal to the source line in an OFF state. A switching circuit supplies multiple pulse signals to the multiple switching elements. A CPU determines pulse widths of the multiple pulse signals. The pulse widths of the multiple pulse signals are determined such that each of the pulse widths of the multiple pulse signals is longer than or equal to a charging time of a pixel electrode and such that the sum of the pulse widths of the multiple pulse signals is shorter than or equal to a horizontal synchronization period.

  • Patent number: 9134836
    Abstract: Provided is an electronic device. The electronic device includes a planar display unit, and a touch panel which is disposed so as to overlap the display unit and is capable of detecting a vertical distance between two-dimensional coordinates along a surface of the display unit and a finger. Resolution of the two-dimensional coordinates becomes finer as the vertical distance decreases. Thus, even when the operating finger is immobilized in a state where the electronic device is fixed, a display of a pointer is not wobbled or a display of a screen is not wobbled. In addition, when a line is drawn using a drawing mode, the line is not displayed jaggedly.
