Patent ID: 8052498

Claim:
A method of forming a color filter touch sensing substrate, the color filter touch sensing substrate being disposed corresponding to a thin film transistor substrate, and a display medium layer being disposed between the color filter touch sensing substrate and the thin film transistor substrate, the method comprising: providing a transparent substrate; forming a first transparent conductive layer and an assistant electrode layer sequentially on a side of the transparent substrate facing the thin film transistor substrate; patterning the first transparent conductive layer and the assistant electrode layer, wherein the first transparent conductive layer after patterning forms at least two first transparent sensing pads and at least two second transparent sensing pads, the assistant electrode layer after patterning forms at least two first patterned assistant electrodes and at least two second patterned assistant electrodes, the at least two first transparent sensing pads are electrically isolated from the at least two second transparent sensing pads, and the at least two first patterned assistant electrodes are electrically connected to and contact with the at least two first transparent sensing pads, the least two second patterned assistant electrodes are electrically connected to and contact with the at least two second transparent sensing pads, and the at least two first patterned assistant electrodes are electrically isolated from the at least two second patterned assistant electrodes; and forming a black matrix on the side of the transparent substrate facing the thin film transistor substrate to cover the at least two first transparent sensing pads partially, the at least two second transparent sensing pads partially, the at least two first patterned assistant electrodes partially, the at least two second patterned assistant electrodes partially, and the transparent substrate partially, wherein the black matrix is formed by insulating materials.
