We've been keeping an eye on Shinoda Plasma's curved PTA (plasma tube array) technology since 2007. What started as a single 43-inch prototype grew to 125-inches in 2008. Now, Shinoda is showing off a 145-inch diagonal prototype consisting of six PTA panels stitched together in a 2-meter x 3-meter matrix. The 960 x 720 pixel resolution might not impress you until you consider the weight: just 7.2-kg (15.8-pounds) thanks to the slim PTA panels measuring just 1-mm thick. Impressive compared to 108-inch LCDs that weigh in at 196-kg (430-pounds) and the original Osborne 1 "laptop" that weighed 24.5-pounds. With any luck, these giant displays will be commercialized for signage so we can all simulate crushing motions with two hands.
