EPD (Electronic Paper Display, e-paper) is a special type of display that does not need electricity to sustain the projected image. Just like real paper, e-paper also does not require backlight and the displayed image resembles ink on paper (hence the name). Thanks to minimal energy requirements, perfect readability in the sunlight and unlimited viewing angles, EPD displays are the best choice for many industrial and consumer applications such as: e-prices, weather stations, smart homes, modern timetables, interactive signs, badges, smart watches.
This is a 2.9 inch eink ePaper display with 296×128 resolution, SPI interface, capable of displaying images in black, white and yellow. Due to the bi-stable, the image once updated can stay on the display even when power is completely disconnected. The image is also high contrast and readable under sun just like printed paper. It is a perfect match for appliances like e-shelf label, smart tag, smart home application, industrial instrument and other related products.
