E Ink unveils Kaleido 4 color e-paper with faster refresh, wider gamut

E Ink has announced Kaleido 4, a new color e-paper display technology that doubles color gamut volume to over 40,000 colors and improves white reflectance and contrast. The company says an added oxide backplate lets the screen refresh fast enough to show video at 18 fps, addressing a longstanding weakness of e-paper displays. Kaleido 4 is currently used only in Hanvon Technology's M10 C II tablet.
