Microcavity effects and the outcoupling of light in displays and lighting applications based on thin emitting films
The outcoupling of light from thin films with a high refractive index is a problem occurring in lighting and display applications based on different technologies. Three different solutions are suggested: one-dimensional microcavity structures, roughness in the emitting layer, and roughness in the substrate/air interface. The advantages and drawbacks of these principles have to be evaluated for different applications. (c) 2004 Elsevier B.V. All rights reserved.
