Nanov Launches a Solar-Powered Outdoor E-Paper Display

Screen Shot 2022 06 30 at 9.53.47 AMNanov launched a solar-powered outdoor E-Paper Display (EPD) for signage and bus stop signs that can show bus arrival schedules or be used for wayfinding maps, all using low-powered dual 13.3″ E-ink displays for transit applications.

The company engineered multiple models: a 32″ Solar-powered E-Paper bus shelter sign and another utilizing two 13.3″ e-ink bus stop digital signage. The dual 13.3″ solar panels generate 75 watts of sustainable energy in three hours under New York City weather conditions and Lithium-Ion battery energy storage. The system includes the screens, LTE modem, Real-Time Passenger Information System, LED lighting to make the screen readable during the night, and Lithium ION energy storage system.

Here’a a video we shot of it at InfoComm 2022:

The EPD system consumes 25 watts per day and the signs can last up to three days without sun. Three days are necessary during the winter months in the greater Northeastern region of the US. The company used optical bonding technology which glues together the e-paper and the front enclosure protective glass for vandal-proof technology and to prevent winter condensation on the screen.

LED lighting has been optically bonded for the night vision of the display. To have a low consumption system, the monitors will run on a cloud-based content management system with thin computer technology to broadcast real-time bus arrival times. To operate in the winter months, an automatic temperature control heater system will turn on in severe conditions (-25 centigrade). The system can display saved static bus schedules, transit mapping, and alarm messages for low power, internet disconnection, overheating, freezing screens, computer malfunctions or other abnormal situations.

A version of this product also won a Best of InfoComm 2022 award.
