A data processing system is disclosed, which includes a system unit, a display device for displaying data generated by the system unit, data communication means for communicating display data between the display device and the system unit, a peripheral device, and peripheral communication means for communicating data between the peripheral device and the system unit. In accordance with the present invention, data is communicated between the system unit and the peripheral device via the display device. Data is transferred between the display device and the peripheral device utilizing a wireless communication link, thereby eliminating the problems associated with electrical cables. In a preferred embodiment of the present invention, the wireless communication link includes a first transceiver means located in the display device and a second transceiver means located in a peripheral device. In a first embodiment, the first and second transceiver means comprise infrared transceivers. Utilizing infrared transceivers advantageously reduces undesirable radio frequency emissions. Alternatively, the first and second transceiver means may comprise a radio frequency transceiver.
