The electronic ink screen uses the "microcapsule electrophoresis display" technology for image display. Its 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 the picture without backlight, and the viewing angle is almost 180°.
