Advantages of Eink B>
1. E-paper display uses microcapsule electrophoretic technology for display, the principle is: charged particles suspended in transparent fluid move to the sides of the microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just like traditional printed paper.
2. The e-paper display will clearly display images/texts under the light bulb or natural light, no backlight required and features almost up to 180 degree viewing angle. It is usually used as an e-reader because of the paper-like effect.
