  • Publication number: 20120194444
    Abstract: A method of tracing touch paths for a multi-touch panel is disclosed. A basis touch point obtained from the multi-touch panel, a predicted touch point generated according to the basis touch point, and a detected touch point obtained from the multi-touch panel are provided. A reported touch point is then generated according to the basis touch point, the predicted touch point and the detected touch point based on a parametric curve.

  • Patent number: 8217902
    Abstract: Disclosed is a conductor pattern structure of a capacitive touch panel. First-axis conductor assemblies and second-axis conductor assemblies are formed on a surface of a substrate. Each first-axis conductor assembly includes a plurality of first-axis conductor cells that are interconnected by first-axis conduction lines. An insulation layer is formed on a surface of each first-axis conduction line. Each second-axis conductor assembly includes a plurality of second-axis conductor cells that are interconnected by second-axis conduction lines. Each second-axis conduction line extends across the insulation layer of the associated first-axis conduction line.

  • Publication number: 20040165141
    Abstract: A method of forming a liquid crystal panel is provided. A first substrate and a second substrate are provided. A sealant having an injection opening is formed between the first substrate and the second substrate. The sealant is fabricated using an etchant resistant material. Thereafter, liquid crystals are injected into the cavity bounded by the first substrate, the second substrate and the sealant through the injection opening. After sealing the injection opening, a substrate thickness reduction process is performed to reduce the thickness of the first substrate and the second substrate.
