WORKING PRINCIPLE： The working principle is charged nanoparticles suspended in the liquid are subjected to the action of the electric field to migrate, and reflect under the ambient light to form a display effect close to that of traditional printing paper.

VIEWING ANGLE： The electronic ink screen can clearly display the picture under ambient light such as lighting, natural light, etc., 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.

MICROCAPSULE ELECTROPHORESIS DISPLAY：The epaper display uses "microcapsule electrophoresis display" technology for image display.

MULTI MODE SELECTION：E paper display supports multi mode selection. Through the mode switch button, users can freely switch between GC16, A2 and A2+ three modes.

SPEED ADJUSTMENT：Electronic ink screen supports 10 contrast adjustments and 5 display speed adjustments. With the mode selection, users can match their own display effects.
