Abstract
This disclosure describes devices that can integrate a solar energy collection device, such as a solar collection film or panel, and an illuminated display. Embodiments of the present solution include a display that includes a solar film layer topped by a transparent or semi-transparent display layer enabled by an edge-illuminated light guide. The semi-transparent display can allow sufficient light transmission to cause the solar layer to charge an integrated battery, which, in turn, can illuminates the display. This solution can enable wireless displays that can be seen day or night.
