Disclosed are devices and methods for intradevice communication in a mobile communication device having a display. A method includes providing a supply signal and superimposing a data signal onto the supply signal. The method further includes driving a light source with the supply signal and the superimposed data signal to produce light to illuminate the display. Also included is sensing the light illuminating the display with an optical sensor, which is coupled to a receiver circuit, and then distinguishing the data signal from the sensed light with the receiver circuit. An image is formed on the display using the data signal distinguished with the receiver circuit.
