E Ink has launched E Ink Kaleido 4, its next-generation color ePaper technology, and Hanvon Technology's M10C Gen 2 ePaper notebook is the world's first device to adopt it. Kaleido 4 doubles color gamut volume to over 40K, lifts white reflectance by 15%, improves contrast by 50% and adds 18fps video playback on a new Oxide-TFT backplane.
