Abstract:
1. A method of fabricating an illumination source, capable of producing light, having a CRI value of at least about 80, the method comprising: fabricating a first stripe, having a first area, the first stripe comprising a first organic emissive layer, adapted to emit a first spectrum of light; fabricating a second stripe, having a second area, the second stripe comprising a second organic emissive layer, adapted to emit a second spectrum of light; wherein each stripe has an aspect ratio greater than about 4 and a width greater than about 0.5 mm; the first organic emissive layer in the first stripe emits the first spectrum of light, the second organic emissive layer in the second stripe emits the second spectrum of light, and the first spectrum of light is different from the second spectrum of light when voltages are applied across the first and second stripes; and fabricating a drive circuitry for supplying a predetermined drive current to each stripe, which achieves a combination of light emitted from the emissive layers having a CRI value of at least about 80.
