What is an e-paper?
e-paper displays use electrophoretic microcapsule technology to display an image: charged particles suspended in a transparent liquid 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/text in 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.
