  • Patent number: 11937478
    Abstract: A microcavity pixel design and fabrication method for an organic light emitting diode (OLED) array with a high aperture ratio suitable for a light field display. This is achieved by laterally overlapping intermediate electrodes and optical filler layers, reducing the lateral spacing. The OLED layers in the design have a uniform white OLED stack, allowing each layer to be deposited across the OLED array, simplifying fabrication. The optical path length for each subpixel's optical microcavity is optimized through the thickness of the optical filler layers, allowing the white OLED stack to be uniform, reducing fabrication complexities.

  • Patent number: 11925058
    Abstract: A microcavity pixel design and structure allowing for tuning the optical cavity length of the microcavity of a microcavity pixel structure. This is achieved by including an intermediate electrode in the device which has an overhang region to form a connecting area to a bottom electrode, alleviating design restrictions in material type and dimensions throughout the optical microcavity tuning process. A method for the fabrication of a multi-colored microcavity pixel array facilitating the use of blanket deposition methods for select layers within a microcavity pixel structure.

  • Publication number: 20200287165
    Abstract: 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.

  • Patent number: 9972780
    Abstract: A NiOx:electron acceptor nanocomposite based film is prepared by synthesizing NiOx nanoparticles (NPs) by a solvothermal synthesis treatment; dispersing the NiOx NPs and an electron acceptor into an alcohol solvent to form a NiOx:electron acceptor solution; conducting an ultrasonic treatment on the NiOx:electron acceptor solution; and solution-processing the NiOx:electron acceptor solution onto a substrate to form a NiOx:electron acceptor nanocomposite based film on the substrate. The film may be used to form an optoelectronic device such as solar cell, a light emitting diode, a laser, or a photodetector.
