A two layer touch panel structure utilizes direct-bonded touch panel and liquid crystal display (LCD) stackups for devices like tablets and computers. The top surface of a color filter and a receive conducting layer are placed close to the surface of the stackup. Placing a layer of conductive material on top of the color filter, on top of the polarizer, or on the cover glass can enable the process to be greatly simplified and cheaper than conventional processes, while maintaining excellent electrical and touch performance, and reducing ITO pattern visibility. Such a process also can utilize a large color filter, enabling significantly more pieces to be formed from a single stack and thus further improving efficiency and cost. |
