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.
