E Ink Kaleido 4 doubles colour gamut and brings video to 18fps
E Ink has launched Kaleido 4, a colour e-paper display platform that the company says doubles colour gamut volume to more than 40K, raises white reflectance by 15% and improves contrast by 50%. Hanvon Technology’s M10C II notebook is the first device announced with the panel; E Ink says its new algorithms support video playback at up to 18 frames per second.
Bottom line — Hanvon’s M10C II is the first Kaleido 4 device, but E Ink has not announced wider adoption plans.
