Your next color E Ink smartphone will have better color, contrast, and 18fps video

E Ink has launched Kaleido 4, so the color e-paper tablet, reader, or monitor you buy next can have a noticeably better screen than the ones on sale now. The company announced its fourth-generation canvas with a wider color gamut, brighter whites, higher contrast, and faster refresh. Hanvon Technology’s M10C II is the first device to use it.

Most color E Ink devices today run on Kaleido 3. This includes the Onyx Boox Tab Ultra C, the first Onyx tablet with that panel, and the Bigme S6 Color+, which Bigme rated at 12fps. The same panel has since moved beyond tablets into products like the 13.3-inch Bigme B13 monitor, which shows color at 150ppi. 

What you get with Kaleido 4

Compared with the previous generation, E Ink says you get twice the color gamut volume, now above 40K. Likewise, white reflectance is up by 15%, and contrast improves by 50%. Per E Ink, the improvement makes images, charts, and presentations look clearer, and cuts the grainy look that color e-paper screens are known for.

The panel also refreshes faster. Kaleido 4 uses a new oxide TFT backplane that handles higher driving voltages, which speeds up screen refresh. New algorithms let it play video at up to 18 frames per second, up from the 12fps Bigme quoted for the S6 Color+. E Ink also redesigned the front light, and says colors look more natural and detailed.

Hanvon M10C II is the first Kaleido 4 device

E Ink says the Hanvon M10C II will be the world’s first product with Kaleido 4. It runs a Qualcomm octa-core processor with 4GB of RAM and 128GB of storage. 

According to E Ink, page turning and scrolling are 27% faster than before. The improvement comes from combining the oxide backplane with Hanvon’s Enhanced Pressure Floating technology and T2000 timing controller.

For writing, you get a wireless, battery-free pen with 8,192 pressure levels. The screen is a micro-etched anti-glare black tempered glass panel that reduces glare and parallax and gives writing a paper-like feel. Hanvon also includes OCR, voice and AI-powered office apps, cloud library sync, ripple-reduction technology, and font rendering changes.
