  • Patent number: 8593416
    Abstract: A touch device includes a touch panel, a sensing unit, and an operation unit is provided. The sensing unit is coupled to the touch panel, for scanning a scan area of the touch panel to output a touch signal. The operation unit is coupled to the sensing unit, for determining the scan area according to the touch signal. When the touch signal corresponds to a first close path, the operation unit defines a close area formed by the first close path as the first sub touch area. When the first sub touch area is undefined, the operation unit chooses a whole touch area of the touch panel as the scan area. When the first sub touch area is defined, the operation chooses the first sub touch area as the scan area.

  • Patent number: 8294048
    Abstract: A sensor structure of a touch panel and a method of determining a touch signal generated by the same are disclosed. The sensor structure includes a plurality of sensor lines disposed on a surface of a substrate, and a control circuit electrically connected to the sensor lines. Each of the sensor lines has a plurality of conductive pads and a conductive line electrically connected the conductive pads. The control circuit receives a touch signal from one of the sensor lines. The touch signal is resulting from a touch capacitance generated between a touch and one of the conductive pads of the sensor line. The control circuit calculates the position of the touch based on the touch capacitance. In addition, the touch capacitance generated by a conductive pad close to the control circuit is larger than the touch capacitance generated by another conductive pad further away from the control circuit.

  • Patent number: 8120593
    Abstract: A method of positioning a coordinate suitable for a touch panel includes following steps. When a touch event occurs, the touch panel generates a corresponding detection coordinate periodically until the touch event ends. When the touch event occurs, the detection coordinate generated by the touch panel is sequentially stored. The touch event is ignored until the number of coordinates generated by the touch panel is greater than or equal to N, and N is a positive integer. When the number of coordinates generated by the touch panel is greater than or equal to N, a touch coordinate corresponding to the touch event is generated according to the last generated N detection coordinates. The above-mentioned step of generating the touch coordinate is repeated according to a cycle of generating the detection coordinate by the touch panel so as to renew the touch coordinate until the touch event ends.

  • Publication number: 20100309171
    Abstract: A method of scanning a touch panel is provided. The present method includes following steps. First, a scan area is defined according to the coordinates of a detected touch signal. Next, the scan area is scanned during a predetermined period to detect a next touch panel. After the predetermined period, a sensing range of the touch panel is scanned to re-define the scan area. Because the scan area is smaller than the sensing range of the touch panel, the time and power consumed by the scanning operation can be both reduced by detecting the touch signals within the scan area.
