That's how Sony decided to showcase its new display technology. As moving images were displayed on an organic thin film transistor (OTFT) matrix, the whole setup was repeatedly rolled around a 4 millimeter tube. The ultra-thin 4.1" display, which featured a density of 121 ppi, was even stretched.
The key breakthrough that allowed this minor miracle to occur, according to Sony, was the development of flexible 20 micrometer-thick integrated circuits.
These ultra-thin ICs replace conventional "rigid" chip-based counterparts that were apparently a limitation in display engineering. Sony also made sure to point out that the final production process will be energy efficient and eco-friendly, to quote a corporate responsibility cliché.
Now we're not really sure if consumers will go gaga over gadgets they can roll up into a pencil-sized case (ok, maybe they will?). And artifacts appeared as the ultra-thin display was manipulated. Still, let's hope Sony's actually a year or two away from perfecting this technology for mass enjoyment. Nothing would be more awesome than unfurling an HDTV for an avid audience come 2012. Or what about a full-color HUD interface built into glasses?source
