Advantages Of EINK E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when 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 e-reader due to its paper-like effect. Application Examples Suitable For Price Tags, Asset/Equipment Tags, Shelf Labels, Conference Name Tags... What do you need to note about e-Paper refreshing? Answer: Refresh mode Full refresh: e-Paper flicker when full refreshing to remove ghost image for best display. Partial refresh: It don't flicker if you use partial refresh (only some of the two-color e-paper support partial refresh). Note that you cannot use Partial refresh all the time, you should full refresh e-paper regularly, otherwise, ghost problem will get worse even damage. Refresh rate When using, you should set the update interval at least 180s.(except Partial supportable types) Please set the e-Paper to sleep mode or power off it directly, otherwise, the e-Paper is damaged because of working in high voltage for long time. Working place We recommend you to use the e-Paper indoor. If you need to set the e-paper outdoor, Please place the e-paper in shadow and protect it from UV. When you designed you e-paper product, you should take care about the working situation like temperature, humidity, etc. User Manual: https://www.waveshare.com/wiki/2.66inch_e-Paper_Module
