<p>A touch panel includes a display unit (200), a transparent substrate (220, e.g. a polarizer) disposed on top of the display unit, multiple sensing series (241) disposed on the transparent substrate, multiple peripheral circuits (242) disposed on the transparent substrate, each being electrically connected to a corresponding one of the sensing series, and an outer frame (230) for holding the display unit and the transparent substrate along their peripheries and for masking the peripheral circuits. A transparent protective layer (250) may be mounted on top of the substrate. The transparent conductive layer and metallic layer may be formed by a roll-to-roll sputtering or coating process and patterned by roll-to-roll photolithographic or laser etching process. The peripheral circuits may alternatively be printed (e.g. ink jet printed).</p> |
