  • Touch panel having edge electrodes extending through a protective coating
    Patent number: 6842171
    Abstract: A method of manufacturing a touch screen panel, the method including applying a resistive coating to one surface of an insulative substrate, applying an insulative protective coating to the resistive coating, depositing a conductive edge electrode pattern including a plurality of edge electrodes on the protective coating, and firing the panel until the edge electrodes etch through the protective coating and make electrical contact with the resistive coating.

  • Touch panel with improved linear response and minimal border width electrode pattern
    Patent number: 6549193
    Abstract: A touch screen panel including an insulative substrate; a resistive layer disposed on the insulative substrate; and a plurality of spaced conductive segments on the resistive layer along the border thereof. The conductive segments are disposed in rows, and every row has at least two segments which face at least a portion of three segments in the next inner row for optimizing the linearity of the touch screen panel and at the same time reducing the space occupied on the touch screen panel by the conductive segments.
