10 November 2004 Increasing OLED output light efficiency via holography
Author Affiliations +
Following a brief review of OLED structures and emission models, we have proposed a phase holographic method to modify both sides of the substrate of an OLED to increase its output light emission efficiency. The holograms are designed with special masks simulating the emission layer of the OLED. A single source macroscopic phase holographic experiment is used to illustrate the idea. Limitations on diffraction efficiency due to the dynamic density and position variations of the excitons and near-field subwavelength wave propagation phenomena in a real OLED device have been discussed.
