Abstract
A programmable display apparatus powered by solar cells is disclosed. The apparatus is with high portability and may be deployed to render advertising messages at isolated locations outdoor. Multiple solar cells are arranged on the device either underneath a transparent or a semi-transparent display panel and/or in areas uncovered by the panel. The solar cells arranged underneath the display panel may have a larger area than the panel, which allows the solar energy is collected with an enlarged solar cell arrays while maintaining the portability of the device. A communication device is integrated with the display system to provide means to communicate with an external device or a communication network. According to one embodiment, visible light communication is employed to deliver updated advertising messages and control data to the display system outdoor. According to one implementation of the embodiment, at least one solar cell connected to a voltage or a current sensing circuit is used as a photo detector to receive the modulated visible light beam and to convert the signals into electrical ones.
