Description

3inch E-Paper (G) Raw Display, 400 × 168, SPI Interface. E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: that charged particles suspended in the clear fluid will move to the sides of the microcapsule when an electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
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 an e-reader due to its paper-like effect.
