2.9 inch electronic ink screen bare screen
Description
The electronic ink screen uses the "microcapsule electrophoretic display" technology for image display. It’s working principle is that the charged nanoparticles suspended in the liquid undergo the action of an electric field to migrate, and reflect under ambient light to form a display effect close to that of traditional printing paper. The electronic ink screen can clearly display pictures under ambient light such as light and natural light, without backlight, and the viewing angle can reach almost 180°. Because of its display effect comparable to traditional paper, it is often used in applications such as readers.
