A Study of Illumination and Communication using Organic Light Emitting Diodes

Organic light emitting diodes (OLEDs) are an attractive proposition for replacing large area Lambertian sources in lighting systems. Commercial devices can meet the luminance requirements for such systems, and small area high (∼10 MHz) bandwidth devices have been reported, but at present, not one device combines these features. However, this paper shows that 1) there is considerable potential to optimise the layout of luminaires within a room to improve illumination levels and communication and 2) that it is feasible to construct a 100 Mbps indoor broadcasting system with proper equalisation of a state of the art (10 MHz) OLED. Experiments show that 10 Mbps data transmission is possible using an experimental device.
