First Foldable Color E-Reader Makes Its Debut

Storing an entire library of books on a single device is a fantastic way to quench your thirst for knowledge or entertainment without cluttering your home with shelves. However, traditional e-readers haven’t quite replicated the tactile feel of a real book—until now. E Ink has teamed up with Readmoo to unveil the first-ever foldable color e-book reader.

The Age of Foldable Devices

Foldable devices are all the rage these days, from smartphones to tablets and even items like helmets and bikes. The idea behind these gadgets is simple: create something large that can be folded down into a compact form for easy portability. The mooInk V, developed by Readmoo and E Ink, certainly fits the bill, but it goes a step further by offering an experience that’s closer to holding an actual book compared to other e-readers.

This “world’s first foldable color e-book reader” boasts a Gallery 3 color ePaper display that bends over a hinge, providing 8 inches of screen space. Users can enjoy digital content like comics and picture books in this tablet-like format, though it’s unclear if split-screen functionality is supported.

Thanks to this advanced E Ink technology, the device promises faster response times and a color resolution of 300 pixels per inch, resulting in more vibrant colors, richer saturation, and improved contrast. However, the device doesn’t appear to have a built-in front light, meaning you’ll need some ambient lighting to read comfortably.

When folded up between reading sessions, the device features a gap at the hinge—similar to early foldable smartphones—and a visible crease. E Ink’s assistant manager, Liu Dajing, explained that this is due to the ePaper layer being about four times thicker than an OLED screen, which makes foldable electronic paper much harder to develop.

Panel Optimization and Durability

The team optimized the Gallery 3 panel used in the mooInk V for stacking and subjected it to 200,000 bend tests to ensure its durability.

We’re thrilled that the first foldable color e-book reader is nearing release, said Zhenghao Li from E Ink. E Ink has made great strides in advancing ePaper technology, transitioning from black and white to color, and increasing panel sizes to meet various needs and applications.

Foldable technology is an area where we’ve invested heavily in R&D. Now that we’ve successfully developed the first foldable e-book reader, we’re excited to offer consumers a new reading experience that’s light, portable, colorful, comfortable, and natural.

Readmoo showcased the mooInk V at Touch Taiwan 2025 this week, reporting that the device is production-ready and weighs around 255 grams (~9 ounces). However, details about pricing and availability remain undisclosed by both companies.
