Pixelated E-Paper Display Powered & Updated Wirelessly

Bistable display materials, such as e-paper, promise to enable displays with the best properties of both paper and electronic displays. A research team from the University of Massachusetts Amherst, University of Washington, and Intel Labs has created a bistable display tag that, from an energy standpoint, is capable of perpetual operation. An off-the-shelf, near field communication (NFC)-enabled phone generates radio frequency signals carrying both the information and energy necessary to update the display. After the update is complete, the display continues to present the information with no further power input. The NFC-WISP, a software-defined NFC tag platform, was used to develop this e-ink display tag. The NFC-WISP is an open source platform. This video demonstrates the capabilities of the display tag as a companion display for a mobile phone.
