It looks like a color e-ink tablet was recently shown off at an exhibition in Germany that is about the size of an A4-sized paper. It’s unclear whether color e-ink will make it to a commercial drawing tablet in the future as the exhibition shows “the idea of a promising future of electronic ink for art, enabling us to meet a curious audience, ambitious artists and dynamic professionals,” according to The Digital Reader. SlashGear is reporting that it’s unclear who created the tablet and its color e-ink display, but sponsors for the exhibition include e-ink makers Bridgestone, Epson and Samsung.
