Although E Ink’s electronic paper technology works well in devices such as e-readers and e-notes, it is less suitable for devices that are intended to do more than just read and take notes. So, while Dasung’s new Link appears to be a phone, it’s actually a pocket-sized E Ink screen designed to occasionally connect to a user’s more capable smartphone.
With the introduction of electronic paper screens capable of displaying full colour text and images in recent years, a number of companies have released E Ink-based smartphones designed to make staring at them for hours easier on the eyes, as well as to leverage the low power consumption of E Ink screens to help maximise a mobile device’s battery life. However, due to the limitations of electronic paper technology, such as screens with low refresh rates, these devices, such as the Hisense A5C we tested back in 2020, have been pretty bad.
