What is an E-Paper E-Ink?

E-Paperdisplays use electrophoretic microcapsule technology for display: charged particles suspended in a transparent liquid will move to the sides of the microcapsule when an electric field is applied, making the microcapsule visible by reflecting ambient light, just like traditional printed paper. The E-Paper display clearly displays images/texts under lamplight or natural light, requires no backlight, and has a viewing angle of nearly 170°. This type of display is usually used in e-book readers because of its paper-like effect.
