Osaka, Japan--Transparent touch panels used in PDAs (personal digital assistants), pocket PCs, and other consumer electronics products are evolving. Replacing traditional glass substrates with plastic results in touch panels offering greater shock resistance, higher light transmission, and lower reflection. In addition, end products weigh less and present a slimmer profile.
Until now, glass has been the common substrate for transparent touch panels. Conductive layers of indium tin oxide (ITO), applied by high-temperature sputtering technology and separated by micro-dot
