  • Publication number: 20120081332
    Abstract: 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.

  • Publication number: 20120075243
    Abstract: 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.

  • 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.

  • Patent number: 7751076
    Abstract: A control apparatus used in an image forming apparatus has a CPU board (100) and a relay board having I/Fs (311-314) and a CPU (301). The I/Fs are connectable with driver boards (5001-5004), and have common standards. The CPU detects each connection state of the driver boards to the I/Fs, decides an ID for the relay board according to the connection state, and performs consistency control to secure consistency of control between the driver boards, based on the ID for the relay board. The CPU board is communicatably connected to the relay board. The CPU board obtains the ID for the relay board 300, and performs control according to the ID for the relay board.

  • Publication number: 20100060609
    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.
