  • Patent number: 8662692
    Abstract: In a touch panel, a cover lens, a sensor unit, and a panel cell are assembled first via glue to form a panel component, where a concave portion is also formed at the side of the panel component. An assembling frame is used to extend into the concave portion and covering around the side and bottom of a backlight module so as to assemble the panel component with the backlight module. Wrapping tape and further fixtures that were used to combine the backlight module and the cell may be removed to reduce the overall cost of the touch panel, while the yield rate of the adhering process may be effectively promoted since the adhering process is done simply on glass components.
