    摘要： Provided is a display device equipped with a touch panel, including a front panel arranged above a capacitive touch panel at a predetermined distance away therefrom, in which the touch panel includes a plurality of X electrodes and a plurality of Y electrodes, and the X electrodes are sequentially applied with pulse signals and the Y electrodes receive the pulse signals. When an arbitrary point on the front panel is touched, the touch panel computes a touched point on the touch panel by using both the received pulse signals obtained from the Y electrodes in a case where the front panel is not deformed and the received pulse signals obtained from the Y electrodes in a case where the front panel is deformed. With this, an erroneous operation in which a measurement value is lowered to finally disappear is prevented.

    摘要： 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.

    摘要： 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.

    摘要： Provided is a touch panel which completes touch detection within a specified time even when the maximum number of touch points is set to be large. A control portion assigns priorities for being given a high coordinate precision to the respective touch points based on the state of the touch points. The control portion selects coordinate calculation algorithms having coordinate precisions corresponding to the priorities of the respective touch points from among a plurality of coordinate calculation algorithms, and calculates required calculation time for calculating coordinates of all the touch points. The control portion determines the priorities so that the calculated required calculation time is equal to or shorter than a specified time. The control portion selects coordinate calculation algorithms corresponding to the priorities and calculates the coordinates of the respective touch points.

    摘要： A touch panel of capacitance type includes plural X-electrodes, plural Y-electrodes, and a Z-electrode. Each of the X-electrode and the Y-electrode is formed to have pad portions and thin line portions alternately arranged in an extending direction. The pad portion of the X-electrode and the pad portion of the Y-electrode are arranged without being overlapped in a planar view. The Z-electrode is electrically in a floating state, and formed to be overlapped with both the adjacent X-electrode and the Y-electrode in a planar view. The touched position is calculated based on a local minimal point as an intersection with the interelectrode capacitance value that is equal to or smaller than each of the interelectrode capacitance values of four peripheral intersections among those at the intersections between the plural X-electrodes and the plural Y-electrodes.

    摘要： 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. In one embodiment, the touched area is assumed to be, for example, circular in shape. A width in an X direction (overlap width) and a width in a Y direction (overlap width) of an overlap area where the touched area in a circular shape and an electrode area overlap each other is determined based on sensor measured values. When the overlap width and the overlap width 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.
