To all the E-PAPER lovers,
We develop cool gadgets using E-PAPER displays — for people who love the calm of ink, the texture of paper, and the beauty of technology that doesn't shout.
We believe screens don't have to glow. That batteries don't have to be charged. That technology, at its best, should fade into the background and let the design speak.

Understanding E-Paper display technology
Electronic paper (’E-Paper’) is a type of reflective display that mimics the look of ink on real paper while adding the flexibility of digital content. Unlike backlit LCD or OLED screens, E-Paper is naturally visible in sunlight, uses very little power only when the image updates, and stays visible without electricity once the page is set.
