The e-paper industry is undergoing a pivotal transition from black-and-white to color. On October 15, at the 2026 Second E-Paper Ecosystem and Industry Integration Innovation Development Forum, E Ink Holdings and Hanwang Technology jointly unveiled the next-generation color e-paper technology E Ink Kaleido 4, alongside the world's first end product powered by it—the Hanwang M10C Gen 2 color e-paper office tablet. The move marks a substantive breakthrough in core metrics such as color performance, refresh speed, and dynamic display, as e-paper devices extend their target use cases from simple digital reading toward professional office work and information-intensive tasks.

E Ink Holdings Chairman Li Zhenghao said at the launch that color e-paper continues to evolve toward richer, more natural color rendering, with E Ink Kaleido 4 delivering improvements in color performance, brightness, contrast, and dynamic display capability while preserving a paper-like reading experience.

E Ink Kaleido 4 Promises Faster Refresh and Richer Color for Next Wave of E-Readers - BigGo Finance

The next generation of color e-paper is arriving with a substantial performance leap, as E Ink Holdings unveiled its Kaleido 4 platform with claims of doubled color range, brighter whites, and a refresh rate fast enough to handle video. The Taiwanese display maker announced the technology on October 15, naming Hanvon Technology's M10C II smart notebook as the first commercial device built around the new panel. The upgrade targets long-standing complaints about color e-readers, where text often appears softer and images more washed out than on monochrome screens. E Ink says Kaleido 4 doubles the color gamut volume of its predecessor to more than 40,000 colors, while white reflectance climbs 15 percent and contrast improves by 50 percent. Perhaps most notably for a display category historically constrained by sluggish refreshes, the new panel can play video at up to 18 frames per second.
