  • Patent number: 8847914
    Abstract: A static capacitance type touch panel, a control unit electrically connected with X and Y electrodes for detecting a touch position based on a measured value of a static capacitance between the X and Y electrodes. The control unit includes a predetermined touch threshold for detecting a peak, a near-peak range and a non-near-peak range, a first parameter for determining a value of the near peak range, and a second parameter for determining a value of the non-near-peak range. The first and second parameters are respectively predetermined for reduction of a noise influence from the measured value of the static capacitance between the X electrode and the Y electrode.

  • Patent number: 8542213
    Abstract: In a touched position detection method for a touch panel for detecting a touched position, based on measured values by a plurality of sensors, presence of a touch is determined when a measured value by a sensor exceeds a touch threshold. As a touch threshold, a value which cannot be attained due to a mere noise but can due to presence of a touch is set. With respect to sensors located in the vicinity of a sensor showing a high measured value, a higher weighted value is applied to modify a measured value in a touched position calculation process than that to be applied to other sensors.

  • Publication number: 20100259504
    Abstract: Provided is a touch-panel device capable of detecting a touched position with high accuracy even when a touched area extends off an electrode area. According to the present invention, the touched area is assumed to be, for example, a circular in shape. A width in an X direction (overlap width (X46)) and a width in a Y direction (overlap width (Y47)) of an area where the touched area in a circular shape and an electrode area (6) overlap each other may be determined based on sensor measured values. When the overlap width (X46) and the overlap width (Y47) are different from each other, it is judged that the touched area extends off the electrode area, and a position of a center of the touched area in the circular shape is calculated as the touched position.
