Claim Text:
1. A method of forming a curved capacitive touch panel, comprising: providing a curved glass substrate; providing a flat flexible printed circuit board (FPCB) with at least one of capacitive touch sensing and detecting capability; bending the flat FPCB along at least an axial direction to form at least a two-dimensional curved FPCB; wherein the at least two-dimensional curved FPCB respectively comprise curved sidewalls; upon formation of the curved FPCB, aligning the curved FPCB to the curved glass substrate; and bonding an outer curved surface of the curved FPCB to an inner curved surface of the curved glass substrate, thereby forming the curved capacitive touch panel having a display area and at least one touch-sensing area, wherein the display area and the touch-sensing area are separately distributed on the area of the curved glass substrate, and at least another touch-sensing area distributed on the curved sidewalls; wherein the curved capacitive touch panel performs as an outer case for containing an electronic device, and a display panel of the electronic device is aligned to the display area, wherein the touch position is detected when a touch on the touch-sensing area results in capacitance effect.
