    摘要: Optical cavities in a stacked organic light emitting device (SOLEDs) can shift or attenuate the light emitted by the individual organic light emitting devices (OLEDs) in the stack. Interference caused by reflections within the stack, absorption, positioning of the light source, and the polarization of the emitted light can all determine how the spectra of the emitted light are affected by the SOLED structure. A detailed model that provides a good fit to measured SOLED emissions can be used to predict how a SOLED will affect light emitted by OLEDs. As a result, SOLED geometries that will optimize color saturation and external quantum efficiency can be predicted.

    摘要: A method is disclosed for fabricating organic light emitting devices (OLEDS) containing an indium tin oxide (ITO) layer that is deposited onto a fragile layer. The ITO layer is fabricated using a low, non-damaging, ITO deposition rate until a protective ITO layer is formed, at which point the ITO deposition rate is increased to a substantially higher deposition rate without causing damage to the underlying layers. OLEDs fabricated using the accelerated ITO deposition rate could be made with I-V characteristics having no practically discernible difference from the I-V characteristics of an OLED in which the ITO deposition rate was kept at a low deposition rate throughout the ITO deposition process.
