Fresh from its efforts to disguise solar cells as plant leaves, Japan's National Institute of Advanced Industrial Science and Technology (or AIST) is now boasting about some advances it's made in flexible displays, which it says will offer a whole host of benefits for e-paper-based devices. The big deal with this one is that all the processes needed to fabricate the organic TFT were done with microcontact printing, which allowed 'em to achieve a pixel pitch of 127μm even in its their initial 6x6-inch prototype, with the display also working effectively over its entire surface. That doesn't mean that it's quite ready for commercial use just yet, however, although the institute is promising to have A4-sized prototype ready by 2010, with actual e-paper products set to follow sometime around 2015.
