Control of the emission characteristics of a light source in a light field display poses a significant benefit in the resulting 3D display quality for current and future technologies. A design system for microcavity OLEDs of any wavelength is detailed, which combines theoretical background with FDTD optimizations, permitting microcavity design of any OLED configuration. The resulting output profiles for microcavity OLEDs designed and fabricated with this method are compared to standard OLEDs and provide a reduction in spectral bandwidth, and a decrease in angular output.
