Made famous by the Amazon Kindle, e-paper is an electronic display technology which mimics the appearance of paper. As a bistable display technology, e-paper can be extremely low power, allowing it 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. In fact, e-paper is so low power that harvested energy can be used to make updates, enabling the use of RFID or NFC devices with batteryless EPDs.
