Abstract
A light-energy sensing apparatus includes a photovoltaic element that converts light emitted from a touch screen into electrical energy as power for a processor. Data is transferred, via an interface, between the processor and an electronic device. A signal transceiver is coupled to receive and amplify signals outputted from the processor, the amplified signals being then transmitted to the touch screen; or, alternatively, the signal transceiver is coupled to receive signals from the touch screen, the received signals being transmitted to the electronic device via the interface.
