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.

E Ink's next-generation Carta 1400 e-paper display has been pushed back, with supply-chain sources telling Good e-Reader that mass production won't be ready until late 2027. Partners including Foxconn, Netronix, and Linfiny have received samples for future e-readers. The delay also cascades to the Kaleido 4 and Gallery 4 color e-paper platforms, while rumors point to contrast beyond 20:1, lower latency, and reduced text ghosting.
