E Ink
A company specializing in electronic ink (electronic paper) display technology. E Ink's technology is widely used in low-power display devices such as e-readers and electronic shelf labels.
Core Facts
E-Ink technology was developed by the MIT Media Lab in the 1990s, displaying images through the flipping of charged black-and-white particles inside microcapsules.
E Ink screens require hundreds of milliseconds for each refresh, far slower than the millisecond-level response of LCD screens.
Timeline (last 90 days)
E Ink screens do not emit light themselves; they reflect ambient light and consume power only when refreshing the display, so static display consumes almost no power.
An E Ink screen is an electronic paper display that uses electrophoresis technology to display text and images.
The Remarkable Paper Pro Move features a 7.3-inch narrow-bezel E Ink screen.
Most E Ink screens themselves do not emit blue light, and some devices feature warm front lighting.
E Ink has officially released its new-generation Kaleido 4 color e-paper technology.
Kaleido 4 has improvements over Kaleido 3 in three areas: color saturation, refresh speed, and contrast.
The color e-reader products from Kobo, PocketBook, and Boox, as well as the screen solution of the Amazon Kindle Colorsoft, are all based on E Ink Kaleido series technology.
The screen solution used by the Amazon Kindle Colorsoft is a custom E Ink version, with the custom name Saffron, and the core technical principle is still based on Kaleido's color filter architecture.
The E Ink Gallery series uses a microcup structure and requires no color filter layer, so its theoretical color saturation is higher, but its refresh speed is extremely slow, its cost is high, and its yield is low.
Because of slow refresh speed, high cost, and low yield, the Gallery series is mainly used in scenarios such as electronic shelf labels and public displays, and is rarely used in consumer e-readers.

50%UnverifiedE-ink screens are not suitable for watching video content such as YouTube, while the inner screen of a foldable phone requires a high-refresh-rate color display.
50%UnverifiedE-ink screens are inherently slower to respond than LCD or OLED screens because they require an electric field to physically rearrange charged particles inside microcapsules.
50%UnverifiedEmbedding AI agents into e-ink screens is a new direction that only became feasible after the widespread adoption of low-power edge inference chips.
