Pervasive Displays Aurora Mb E-Paper Displays are electronic display modules that mimic the appearance of paper. Using the same inks as the traditional printing industry, e-paper displays (EPDs) have tiny capsules filled with charged ink particles. When the proper charge is applied, an EPD creates highly detailed images with the contrast ratio and readability of printed material. EPDs are extremely low power, allowing them to be used in devices without the power budget of a traditional LCD display. Once the text and images of an EPD have been rendered no power is needed to maintain the display.
