  • Patent number: 8674249
    Abstract: A capacitive touch panel has precise etching lines formed on a transparent conductive film so as to form with a desired pattern. As a result, the hollowed portion on the conductive film will be reduced greatly and thus the flatness of the capacitance sensing structure will be improved and the transmittances in different areas will tend to be uniform. Thus the image distortion in the screen below the touch panel will be improved. Besides, the etching lines will divide the waste etching areas on the conductive lines into a plurality of small units which can reduce the capacitances of the noises.
