  • Publication number: 20100136868
    Abstract: A method of forming a color filter touch sensing substrate integrates touch-sensing structures/elements of a touch panel into the inner side of the color filter substrate, which faces a thin film transistor substrate, and forms patterned assistant electrodes on the surfaces of the transparent sensing pads for decreasing the equivalent resistance of the touch-sensing structures/elements. Moreover, since an adjacent transparent conductive layer and an assistant electrode layer are patterned to form the transparent sensing pads and the patterned assistant electrodes, a simplified pattern-transferring process can be applied to the transparent sensing pads and the patterned assistant electrodes, or bridge structures can be formed from the assistant electrode layer for electrically connecting between some transparent sensing pads. Therefore, the forming process is simplified.
