E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect. Application examples Suitable for price Tags, asset/equipment Tags, shelf labels, conference name tags...
