Abstract
A cover system for an electronic device may include a cover and a set of non-transitory computer instructions. The cover at least partially covers the installed electronic device. The cover may include a power storage device, an outer surface including a color changing region that includes a phosphor layer that luminesces when energized by an electrical signal, and an electrode for conducting the electrical signal to the phosphor layer. The cover may also include communication circuitry configured to receive a data communication from the installed portable electronic device and electrical circuitry configured to generate the electrical signal in response to receiving the data communication. The set of non-transitory computer instructions may direct a computer processor of the electronic device to establish a communication session with the communication circuitry of the cover to transmit the data communication to the cover.
