  • Patent number: 11968856
    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.

  • Patent number: 11956994
    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.

  • Publication number: 20080182073
    Abstract: A manufacturing method of an artificial strip for imitative rattan/willow furniture is to mix unicolor or multicolor polyethylene (PE) with a catalyst that makes the mixture foam after heating. Then, the mixture is extruded via special shaped opening on a shaping mold to perform the artificial strip with chap and crank patterns. Moreover, the color distribution on the artificial strip can be performed evenly or unevenly to create more versatile appearance. Thereby, the artificial strip has a verisimilitude texture approximately like the natural willow or rattan strips to make the manufactured imitative rattan/willow furniture have excellent appearance.
