well, I find that....Unipixel is not a graphene base issue...it's copper based.
"Touchscreens without ITO
Many electronics require expensive and rare indium-tin oxide (ITO). The scarcity of indium creates significant supply chain risk, delays and higher costs for manufacturers. UniPixel Performance-Engineered flexible electronics can replace ITO with ordinary copper. This reduces supply chain risk and cost."
"Flexible and Transparent Substrates
UniPixel flexible electronics are compatible with both transparent flexible and rigid substrates."
That's the advantage at this point...
"However, the relative immaturity of graphene
also means that researchers’ understanding of
the material may advance quickly. We note that
Samsung, working with Sungkyunkwan University
in South Korea, patented a roll-to-roll transfer
process in 2010 that could significantly advance
the potential of graphene for use in touchscreens.
There have also been rumors that Samsung will be
releasing a phone with a graphene-based flexible
touchscreen (supposedly called the “Galaxy Skin”)
sometime in 2012. We will continue to monitor these
developments, as they may have a major impact on
UniPixel’s competitive position."
