Patent ID: 8350727

Claim:
A touch panel, comprising: a first conductive plate including a first substrate having a surface, a first conductive layer disposed on said surface of said first substrate and exhibiting anisotropic resistivity, and at least one first conductive connecting line, said surface of said first substrate having a peripheral edge, a sensing region covered by said first conductive layer, and a marginal region extending from said sensing region to said peripheral edge, said first connecting line being disposed on said marginal region; a second conductive plate juxtaposed with said first conductive plate in a face-to-face manner and including a second substrate and a second conductive layer disposed on said second substrate, and facing said first conductive layer; wherein said marginal region of said surface of said first substrate has a width ranging from about 100 μm to about 1 mm and each of said first and second conductive layers has a first resistivity in a first direction and a second resistivity in a second direction transverse to the first direction, the ratio of said second resistivity of said first conductive layer to said first resistivity of said first conductive layer ranging from about 100:1 to about 200:1, the ratio of said first resistivity of said second conductive layer to said second resistivity of said second conductive layer ranging from about 100:1 to about 200:1 thereby permitting the reduction of a width of said marginal region of said surface of said first substrate, which permits an increase in said sensing region of said first substrate.
