Advantages of E-Ink Screen
The electronic ink screen uses "microcapsule electrophoresis display" technology to display images. Its working principle is that charged nanoparticles suspended in liquid migrate under the action of the electric field, and form a display effect close to traditional printed paper through reflection under ambient light. The electronic ink screen can display images clearly under ambient light such as light and natural light, without backlight, and the viewing angle is almost 180°. Because its display effect is comparable to that of traditional paper, it is often used in applications such as readers.

Based on Raspberry Pi 40PIN
