These outdoor displays feature E Ink’s epaper technology, making them visible in direct sunlight and ultra-low-power. Even without power, the image remains on the screen.
E Ink displays have the advantage of being low power and sunlight readable, which makes them uniquely suitable for outdoor displays, particularly in areas without a readily available power source, as they can be powered by solar energy. They are ideally suited to public noticeboards, transport timetables, and smart city initiatives. These sign-type applications can leverage widely available live data feeds, which are then formatted for display, along with user-generated text-based messaging, using templates or free-form graphics. Volanti provides demonstration applications together with source code, which can be utilized to develop customized applications for such use cases.
