E Ink debuts Kaleido 4 color e-paper display, first device shown by Hanvon
E Ink has announced Kaleido 4, a successor to its widely used Kaleido 3 color e-paper technology found in most color e-readers. The company says it doubles color gamut volume, increases white reflectance by 15 percent, boosts contrast by 50 percent, and uses a new oxide TFT backplane enabling refresh rates up to 18fps. Hanvon Technology will be first to use the display, in its upcoming M10C II tablet, which will only be sold in China.
GoKawiil's interpretation of the reporting above, not reported fact.
Faster refresh rates and better contrast could make color e-readers feel less sluggish and less washed-out than current Kaleido 3 models, a longstanding complaint about the technology. Since major e-reader makers like Amazon and Kobo haven't yet announced devices using Kaleido 4, it may take time before the improvements reach a wider, non-Chinese market.
- Kaleido 4 doubles color gamut volume versus Kaleido 3 but still caps out at 4,096 colors
- New oxide TFT backplane enables refresh rates up to 18fps, allowing basic video playback
- Hanvon's M10C II, a China-only tablet, will be the first device to use Kaleido 4
Kobo Libra Colour E-Reader — Kobo's Libra Colour uses E Ink's Kaleido color e-paper tech discussed in the article, letting you enjoy comics, magazines, and book covers in color while still reading black-and-white text comfortably. It's a great way to experience current-gen color E Ink before Kaleido 4 panels arrive in future devices.
