Sony is showing a new OTFT driven E Ink prototype. The 13.3" panel offers 1200x1600 (150ppi) resolution, 10:1 contrast ratio, 16 shades of gray and can be bent to a curvature radius of at least 5mm. Indeed had a cool demo showing how the panel bends. This panel is monochrome (they also had a color 13.3" flexible e-paper prototype on show).

Sony uses Peri-Xanthenoxanthene (PXX) for the semiconductor layer of the organic TFT (this is the same OTFT used in Sony's OLED prototype unveiled in 2010).
