The electronic paper used in this product uses "microcapsule electrophoresis display" technology for image display, which is basically, The principle is that charged nanoparticles suspended in a liquid are subjected to an electric field to cause migration. Electronic paper display, It is to reflect the ambient light to display the pattern, no need for backlight, even under the sun, electronic paper display, The screen is still clearly visible and the viewing angle is almost 180°. Therefore, the electronic paper display is very suitable read.
