Patent ID: 7187367

Claim:
A touch panel comprising: a top transparent substrate coated with a top conductive film on its lower surface; a bottom transparent substrate coated with a bottom conductive film on its upper surface; an insulating spacer located between the two conductive films of the top and bottom transparent substrates to separate the two conductive films, wherein when the top transparent substrate is touched by an external force, electric contact occurs between the two conductive films; and a plurality of signal lines, wherein each signal line is disposed on an edge of the top or bottom conductive film and is separated from another conductive film or another signal line by an adhesive, wherein a first trench, recessed into the top transparent substrate, is provided on an edge of the lower surface of the top transparent substrate and a signal line is disposed on the top conductive film in the first trench, or a second trench, recessed into the bottom transparent substrate, is provided on an edge of the upper surface of the bottom transparent substrate and a signal line is disposed on the bottom conductive film in the second trench.
