E Ink Announces Kaleido 4 Color ePaper With Doubled Gamut, 18fps Video
Kaleido 4's video playback and doubled gamut move color e-paper past the document reading that Kaleido devices have served, and Hanvon's M10C II is the first hardware built to test that claim.

E Ink announced Kaleido 4 on October 15, 2026, a color e-paper platform with twice the color gamut volume and 50 percent improved contrast over the previous generation, plus 15 percent higher white reflectance. It supports video playback at up to 18fps. The first device to use it is Hanvon's M10C II e-note, which pairs a new front light with the T2000 timing controller. Japanese release and pricing are unknown.
The M10C II carries a new front light and a battery-free pen with 8192 levels of pressure sensitivity. Hanvon says its own driving technology combined with the T2000 timing controller makes page turns and scrolling 27 percent faster. E Ink describes the panel as layering a color filter over black-and-white e-paper, with an oxide TFT substrate speeding refresh.
Screen graininess is reduced and the contrast gain is 50 percent, per E Ink. The company lists color PDFs, graphs and presentation materials as the content that benefits. Chemically strengthened glass with a finely processed surface is part of the build.
