Product Advantages
Electronic paper utilizes "microencapsulated electrophoretic display" technology for image display. Its working principle involves the migration of charged nanoparticles suspended in liquid under the influence of an electric field. It forms a display effect close to traditional printed paper under ambient light through reflection. After refresh, it does not require power supply and can retain the displayed image for a long time. Electronic paper can display images clearly under various ambient light conditions such as artificial light or natural light. It does not require a backlight and offers an almost 180°viewing angle. Due to its display effect comparable to traditional paper, it is commonly used in applications such as e-readers and labels.
