  • Patent number: 9081462
    Abstract: The present disclosure provides a manufacturing method for a touch panel comprising: disposing an electrode layer extending from touch area of a substrate to periphery area of the substrate, wherein the periphery area surrounds the periphery of the touch area. The method further includes disposing an insulation layer in the periphery area of the substrate to form a shielding layer, making the shielding layer cover the overlapping electrode in the periphery area and making the electrode layer of the touch area and the overlapping electrode locate on the same layer of the substrate so as to avoid fluctuation of resistance value in the electrode layer due to height difference. Meanwhile, adopting the disposition method also maintains insulating performance of the shielding layer. The present disclosure also provides a touch panel made by the manufacturing method.

  • Publication number: 20130038571
    Abstract: The present invention relates to a touch technology and provides a capacitive touch panel which has low-visibility metal jumper. The touch panel comprises of a transparent substrate and at least one metal juniper. A mask layer, reflectance of which is lower than that of the metal jumper, is set between the metal jumper and the transparent substrate to block the light reflected by the metal jumper. The mask layer can reduce light reflection of the metal jumper so as to reduce visibility of the metal jumper.

  • Publication number: 20060249388
    Abstract: The invention provides an electrophoretic deposition method of CNTs for a field emission device. It uses a triode structure having gates and a proper arrangement of applied voltages to improve the selectivity of the conventional EPD method. The electric field around the gates repels the charged or polarized nanostructure suspension in the electrophoresis bath and prevents the charged or polarized nanostructure materials from depositing in the neighborhood of the gates. Therefore, the nanostructure materials are selectively deposited on the cathode. An electrical short circuit between the gates and the cathodes can be avoided. It does not require a masked sacrificial layer, and therefore keeps the manufacturing process simple and the cost down.
