The first folding e-ink tablet transforms an e-reader into a high-end paperback

Readmoo's mooInk V folds like paper, but with vibrant color e-Ink.

: The mooInk V from Readmoo introduces an 8-inch folding E Ink display, promising portability akin to a paperback. Utilizing the E Ink Gallery 3, it employs yellow, cyan, and magenta ink capsules for vibrant visuals, yet may have slower refresh rates. Despite a distinct crease in its fold, Readmoo assures structural resilience after 200,000 bending tests. Weighing 255 grams, its pricing remains unannounced but is anticipated to surpass traditional flat displays.

The mooInk V by Readmoo represents the world's first folding E Ink tablet, bridging the gap between a traditional e-reader and modern high-end design. Utilizing a proprietary folding mechanism, it combines the portability of a paperback with the vibrant color display capabilities of the E Ink Gallery 3 technology. As noted by Kyle Barr in the April 2025 release, this groundbreaking device integrates new materials and an optimized stacking method to transition the standard e-reader into a compact, foldable form without compromising display quality. This approach not only advances e-reader technology but also opens avenues for new product design strategies in digital reading.

The E Ink Gallery 3 technology employed in the mooInk V stands out for its use of color ink capsules in yellow, cyan, and magenta, manipulated by an electric field to enhance color clarity over previous technologies like Kaleido. Although boasting superior color representation, the refresh rate of these displays is notably slower, as highlighted by The Verge, potentially affecting usability for rapid content consumption. This aspect makes the mooInk V more suitable for static displays such as colorful book covers rather than for dynamic reading.

One of the challenges with any foldable technology is the visible crease along the fold line, an issue also present in the mooInk V according to Readmoo. Despite this, Readmoo has reportedly subjected the device to rigorous testing, withstanding 200,000 bending trials, suggesting a durability comparable to the current foldable phone market led by companies like Samsung and Google. However, the inherent risks of wear and tear over prolonged use remain, as reiterated by users who have experienced similar challenges with devices like Samsung Galaxy Flip phones.

The mooInk V's compact build is marked by its aluminum-magnesium alloy shell and a light weight of 255 grams, enhancing its appeal as a portable reading tool. Though pricing and release details have yet to be disclosed, projections suggest a premium price tag due to the advanced folding technology involved. This does put it at a potential pricing disadvantage compared to traditional readers and tablets, as seen with devices like the reMarkable Paper Pro, which already command a high market price due to their specialized features.

In summary, Readmoo's venture into folding e-readers represents a significant innovation in the realm of digital reading devices. It addresses the evolving desires of consumers for portable, yet visually appealing technology. While not entirely free from the common pitfalls of new hardware designs, such as durability concerns and high consumer prices, the mooInk V paves the way for future innovations in the design and functionality of e-readers, potentially influencing trends across related digital markets.
