E Ink announced Kaleido 4, a new version of its color ePaper platform, on October 15. Hanvon Technology’s M10C II smart ePaper notebook is the first announced product using it; E Ink reports gains in color gamut, reflectance and contrast, plus video playback up to 18 frames per second.
E Ink announced Kaleido 4, the latest version of its color ePaper platform, and named Hanvon Technology’s M10C II smart ePaper notebook as the first end product to use it. The company says the display generation improves color gamut, white reflectance and contrast, and supports video playback at up to 18 frames per second, extending the platform’s stated use beyond static reading material.
E Ink says Kaleido 4 has more than 40,000 units of color gamut volume, double the previous generation’s figure. It also reports a 15% increase in white reflectance and a 50% improvement in contrast compared with the prior generation. The announcement does not provide measurement methods or test conditions for those comparisons, so the figures should be understood as the company’s reported specifications.
The platform uses a new oxide TFT backplane, which E Ink says supports higher driving voltages and faster screen refresh. In Hanvon’s M10C II, this is paired with the company’s “Enhanced Pressure Floating” technology and T2000 timing controller. Hanvon says the combination enables 27% faster page turning and scrolling on that device. E Ink also describes a redesigned front light intended to produce clearer, more natural colors.
Hanvon’s device combines the display with office and note-taking features, including OCR, voice functions and AI-powered applications, according to the announcement. It also has cloud library synchronization and a wireless, battery-free pen with 8,192 pressure levels. Hanvon says a micro-etched tempered-glass surface is designed to reduce glare and parallax while providing resistance intended to feel more like writing on paper.
Color E-paper Targets Office Work
The launch reflects an effort to position color ePaper for documents and work tasks that can be harder to handle on monochrome screens. E Ink points to color PDFs, presentations, charts, educational illustrations and engineering drawings as examples of content its updated platform is intended to display. Better color and contrast could make those materials easier to distinguish on an ePaper device, although the announcement does not provide independent testing or comparisons with other display types.
The reported refresh improvement and video support also address limits associated with ePaper’s use for more dynamic content. At up to 18 frames per second, Kaleido 4’s video capability is a stated platform feature, not evidence that every video or application will run smoothly at that rate. For readers considering a device, the M10C II is the first product named, but its performance in everyday use will depend on the finished hardware, software and content.
If the product’s reported improvements hold up in use, the combination of a color display, stylus input and productivity software could appeal to people reviewing documents or taking notes away from a conventional laptop. E Ink and Hanvon describe those as intended scenarios; the release does not establish how widely the device will be adopted or whether it will replace existing office tools.

From Color Platform to First Device
E Ink describes Kaleido 4 as the newest generation of its color ePaper platform. Its announcement frames the update around a broader range of material appearing on eReaders and eNotes, from books to workplace and classroom documents. The company’s focus is on balancing color with brightness, contrast and clarity, rather than treating color reproduction as the only measure of a screen’s usefulness.
The first named product is Hanvon Technology’s M10C II smart ePaper notebook. The release identifies it as the world’s first end product featuring Kaleido 4, a claim attributed to E Ink’s announcement. Hanvon describes the notebook as a wider productivity device, with handwriting, recording and office functions alongside reading. These descriptions set out the companies’ product positioning; the release does not include a launch price, availability schedule or independent review.
The release also links the display changes to device-level engineering. Kaleido 4’s new backplane is one part of the M10C II implementation, while Hanvon’s controller, front-light design and software contribute to the complete user experience. That distinction matters: platform specifications are not the same as a guarantee that every Kaleido 4 product will share the M10C II’s reported page-turning speed or feature set.
“Color ePaper needs to deliver more than simply “color.””

Performance and Availability Details
The announcement does not specify the year of the October 15 release date, nor does it give pricing, sales regions or when the M10C II will be available. It also does not publish test conditions behind the claimed improvements in gamut, reflectance, contrast and page-turning speed. Those details would help readers compare the new platform with earlier devices and assess how the results translate to real use.
It remains unclear whether the 18 frames-per-second video figure applies across applications and content types, or what resolution and other conditions are involved. The announcement provides no independent assessment of image quality, battery life or the M10C II’s AI and office functions. E Ink and Hanvon’s statements describe product specifications and intended uses, not third-party verification.

M10C II Market Details Awaited
The immediate next step is for Hanvon to provide details about the M10C II’s price, release timing and markets. Those details were not included in E Ink’s announcement. Product availability and hands-on testing will show how the platform’s stated display gains perform in a finished device and whether the notebook’s reading, writing and office features work as described.
Further Kaleido 4 products could follow, but the release names only the M10C II and does not announce other manufacturers or devices. For now, the confirmed development is the platform launch and its first named end product; the scale of its adoption and practical benefits remain to be established.
