Abstract: An organic light-emitting diode (OLED) structure including a substrate; a dielectric layer on the substrate having an array of well structures, wherein each well structure includes a recess with side walls and a floor, and the well structures are separated by plateaus; a stack of OLED layers covering at least the floor of the well; a light extraction layer (LEL) in the well over the stack of OLED layers; and a coating covering a portion of the stack of OLED layers such that a top surface of the plateaus is more hydrophobic than a surface in the well on which the light extraction layer is formed.

Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

Abstract: Exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. The subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. The patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. The subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.

Abstract: A light-emitting diode display including a substrate having a driving circuitry and a plurality of light emitting diode structures disposed on the substrate. Each light-emitting diode structure has a light emitting diode with a light emission zone having a planar portion, and a pigmentless light extraction layer of a UV-cured ink disposed over the light-emitting diode. The light extraction layer has a gradient in index of refraction along an axis normal to the planar portion, and the index of refraction of the light extraction layer decreases with distance from the planar portion.
