Pervasive Displays Electronic Paper Displays (EPD) – ePaper are a-Si, active matrix TFTs featuring ultra-low power consumption and SPI interface. These electronic paper displays offer black, white, red, and yellow colors and delicate patterns. The EPD panel requires little power to update and no power to maintain an image because of its bi-stable nature. These electronic paper displays feature a wide viewing angle – nearly 180° and are extra thin and light. The electronic paper displays operate at -10°C to 35°C optimal storage temperature range and 0°C to 40°C ambient temperature range. These electronic paper displays are RoHS compliant. The electronic paper displays are ideally used in Electronic Shelf Labels (ESL), reusable containers, and badges.
