Summary
- No backlight required, the last screen display can be kept for a long time after power failure
- Very low power consumption, basically only consumes power when refreshing
- 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 of its display effect comparable to traditional paper, it is often used in applications such as readers.
- Application scenarios,Applicable to shopping mall price tags, asset equipment labels, electronic shelf labels, conference name tags, etc.
