Abstract:
1. A method of operating a display device, the display device comprising: a first electrode; a small molecule organic light emissive layer deposited over the first electrode, the small molecule organic light emissive layer comprising light emissive material for emission of light, wherein the small molecule organic light emissive layer is a patterned layer which has been deposited by solution processing; and a second electrode deposited over the organic light emissive layer; wherein the display device comprises a resonant structure comprising one of a cavity, a microcavity and an interference structure into which one or more regions of the light emissive material are integrated; and wherein the method comprises: using the resonant structure to spatially narrow the emission of light from the one or more regions by at least one of interference and cavity effects.
