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: 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: A polymer is formed by capping a copolymer-graft-polylactone with an alcohol, wherein the copolymer is copolymerized from an anhydride monomer with a double bond, a monomer with a double bond, and an initiator. The polymer can be mixed with an organic solvent and pigment powder to form a dispersion. The dispersion can be mixed with a binder to form a paint.

Abstract: An outdoor control cable includes a cable, a ground terminal, other terminals, and a connector. The cable includes an insulating coating, power lines enclosed by an insulating layer, signal lines enclosed by the insulating layer, and a metal shield. The power lines and the signal lines are enclosed by the insulating coating. The signal lines are further enclosed by the metal shield. The ground terminal is electrically connected to the metal shield. The other terminals are electrically connected to the power lines and the signal lines. The connector includes a casing, a jack, and the ground terminal and other terminals which are protruded and exposed from the jack. Hence, the outdoor control cable has both power lines and signal lines. The metal shield blocks electromagnetic interference from the power lines. The ground terminal is electrically connected to the metal shield and thereby grounds and guides the electromagnetic interference to earth.
