Flat surface touch device for introducing visual effect
An electrode and an isolation layer of a touch device are the same color, so that a user of the touch device perceives a good visual effect without having to employ expensive optical adhesive and decorative films in the touch device. The front bezel design used in conventional touch devices can thus be abandoned. Further, simpler fabrication, higher yield rate, and lower cost are also achieved.
