A strong influence of emitter position and orientation on rolloff is observed.
Cavity organic light emitting diode. The technology of top emitting micro cavity organic light emitting diodes teoleds is an important candidate for the active matrix display applications owing to their various advantages such as high aperture ratio good color purity and high efficiency. The semi transparent metal cathode plays the crucial role in realizing teoleds structure. It is because oled is basically an optical device and its structure consists of organic or inorganic laye rs of sub wavelength thickness with different refractive indices.
The emission zone is placed in the first second and third antinodes of the electric field in the. The efficiency rolloff is investigated for two oled stacks containing either the phosphorescent emitter irmdq 2 acac or irppy 3 by varying the distance between emitter and metal cathode. Micro cavity top emitting organic light emitting diodes teoleds are now receiving prominence as a technology for the active matrix display applications.
