  • Patent number: 8245535
    Abstract: A method of strengthening glass plate is provided. A plasma treating process is performed on a glass plate so that a surface pore variation of the glass plate after the plasma treating process is reduced relative to the surface pore variation of the glass plate before the plasma treating process, wherein the surface pore variation is a variation degree of surface pores in different unit areas of the glass plate. In the mean time, a melted network crosslinking structure is formed on the surface of the glass plate. Based on the above-mentioned mechanisms, the glass plate is strengthened. The plasma treating process is conducive to strengthen the glass plate whether the plasma treating process is performed before or after the conventional chemical strengthening process.

  • Publication number: 20120050173
    Abstract: The present invention proposes a surface capacitive integrated touch panel and manufacturing method thereof. The touch panel comprises a transparent substrate, an icon or artwork layer coated on the periphery of one side face of the transparent substrate, and the inner periphery of the icon layer is not perpendicular to the adjacent line of the transparent substrate. It also comprises a sensing layer which is stacked on icon layer or artwork layer and the areas on the transparent substrate uncovered with the icon layer or artwork layer. Other than that, it comprises a metal layout and an electrode pattern which are formed from the outer of the icon layer to its inner side. The electrode pattern is formed via coating, printing or spraying. This unconventional way of laminating the electrode pattern structures can effectively lower the overall thickness of the panel and increase yield rate.

  • Publication number: 20120050225
    Abstract: A touch panel includes a transparent substrate, an electrically conductive icon or artwork layer, a first icon or artwork layer, a sensing layer, a metal layout and an electrode pattern. The electrically conductive icon or artwork layer is disposed between the transparent substrate and the first icon or artwork layer. The first icon or artwork layer is so coated as to extend over the periphery of the electrically conductive icon or artwork layer. The electrically conductive icon or artwork layer is electrically connected to a grounding trace to impart the touch panel an improved anti-electromagnetic interference capability, thereby ameliorating the problem of false actuation that frequently occurs between the icon or artwork layer and the sensing layer in the conventional devices.

  • Publication number: 20120009392
    Abstract: The substrate according to the invention includes at least one surface coated with an organic buffer layer and the organic buffer layer is provided with a coating layer on a surface thereof opposite to its surface attached to the substrate. The provision of the organic buffer layer diminishes the effect of the coating layer on the strength of the substrate, thereby maintaining the strength of the substrate.

  • Publication number: 20110234507
    Abstract: The present invention provides an integrated touch panel comprising a transparent substrate, one of an icon or artwork layer, a first layer of optical film, and a first sensing layer. The icon layer or artwork layer is coated on the periphery of one side face of the transparent substrate, and the inner periphery of the icon layer or artwork layer is not perpendicular to the adjacent line of the transparent substrate. The first layer of optical film is stacked on icon layer or artwork layer and the areas on the transparent substrate uncovered with icon layer. The first sensing layer is stacked on the first layer of optical film by sputtering. The interchangeability is included in the patent claim of the present invention. As icon layer or artwork layer is not perpendicular to the transparent substrate, the subsequent cladding of the structures may be completed by sputtering or other methods.

  • Publication number: 20100214230
    Abstract: A two-stage manufacturing process for preparation of an ITO layer includes having first a transparent substrate, e.g., a glass or plastic substrate going through treatment without preheating; the substrate is then sputtering processed in a sputtering chamber under process conditions without heating up to form a amorphous state ITO film on the surface of the transparent substrate; followed with a thermal treatment at a preset temperature to turn the ITO layer into a crystalline state without compromising strength of the glass or the plastic substrate while delivering a durable ITO layer and a structure of ITO layer provided with a specific sheet resistance and/or thickness. The ITO layer produced using the present invention particularly fits to be applied in a touch screen structure.

    Abstract: A method of fabricating transparent conductive film including the following steps is provided. First, a reactive chamber having at least a target and at least a heating device is provided. Subsequentially, a plasma is generated in the reactive chamber, wherein the plasma is located above the target. Next, the plasma is heated by the heating device from a standby temperature to a working temperature. Simultaneously, a hard plastic substrate is passed above the plasma at a specific speed, wherein the particles of the target are bombarded by the plasma so as to form transparent conductive film on the hard plastic substrate.

  • Publication number: 20070193876
    Abstract: A manufacturing method for sputtering an anti-refection layer onto a board at low temperature has the merits of easily being implemented and easily mass-produced. The manufacturing method is used for sputtering multiple anti-refection layers onto a board. The method can be used for mass-producing anti-reflection panels as the raw material for the photo industry. The method is superior to the manufacturing method for producing nebulization anti-reflection panels. This invention utilizes the anti-reflection characteristics of the board structure that is sputtered and stacked alternatively with high index refraction layers and low index refraction layers. A continuous manufacturing process is adopted. The present invention uses plasma to clean the surface of the boards and adopts a traditional sputtering machine. Therefore, it is convenient for installing and mass-producing high quality material.
