A color solar-powered advertising display device and control method based on real-time energy state feedback

Abstract

This invention discloses a color solar-powered advertising display device and its control method controlled by real-time energy status feedback. The color solar-powered advertising display device includes a color solar module structure, a color film layer, and an interface optical layer. The color film layer is a static graphic film layer that can be adhered to and removed for replacement, and it forms a linkage design parameter with the interface optical layer to maintain stable optical alignment. The device further includes an energy harvesting unit, a display control unit, and a control processing unit. The control processing unit generates display limitation control parameters based on the real-time acquired power generation output and energy status parameters, and adjusts the display output when insufficient energy output or abnormal temperature is predicted, so that the device maintains a positive net energy output during display operation, improving energy efficiency and system stability.
