What is an "e ink e paper" display?
The e-paper display, also known as an electronic paper (e paper display) uses electrophoretic microcapsule technology to present data. This means that it mimics the look of regular ink found on traditional paper. Such technology is extremely user-friendly - the screens emit no blue glow, are passively reflective and provide a wide viewing angle. All these features make our eyesight fatigue-free and the reading experience even more enjoyable than before.
