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 black matrix on a side of the transparent substrate facing the thin film transistor substrate, wherein the black matrix is formed by insulating materials; forming at least two first patterned assistant electrodes and at least two second patterned assistant electrodes on the side of the transparent substrate facing the thin film transistor substrate, the at least two first patterned assistant electrodes and the at least two second patterned assistant electrodes being disposed corresponding to part of the black matrix respectively, and the at least two first patterned assistant electrodes being electrically isolated from the at least two second patterned assistant electrodes; forming a first transparent conductive layer on the side of the transparent substrate facing the thin film transistor substrate to cover the at least two first patterned assistant electrodes, at least two second patterned assistant electrodes, the black matrix, and part of the transparent substrate; patterning the first transparent conductive layer to form at least two first transparent sensing pads, at least two second transparent sensing pads and at least one first bridge structure, the at least one first bridge structure electrically connecting to the at least two first transparent sensing pads, the at least two first transparent sensing pads being disposed on the at least two first patterned assistant electrodes and on the black matrix under the at least two first patterned assistant electrodes, the at least two second transparent sensing pads being disposed on the at least two second patterned assistant electrodes and on the black matrix under the at least two second patterned assistant electrodes, and the at least two first transparent sensing pads being electrically isolated from the at least two second transparent sensing pads; and forming at least one second bridge structure electrically connecting to the at least two second transparent sensing pads, wherein the at least one second bridge is electrically isolated from the at least one first bridge structure.
