  • 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: 20230277286
    Abstract: A micro-scale mist teeth cleaning device includes console creating air under pressure and water under pressure. The console is connected to a mouthguard that is in the form of an outer ridge and an inner ridge with space in between for the teeth of a patient. The mouthguard includes a receptor for receiving the air and water under pressure, and has tubes for separately distributing the air under pressure and the water under pressure along the outer and inner ridges. The mouthguard further includes openings along the inner side of the outer ridge and the outer side of the inner ridge facing the location of the patient’s teeth when the mouthguard is installed in the patient’s mouth. The tubes for the pressurized air and the water intersect at each opening at an angle such that they act to eject a micro-scale mist from the opening onto the user’s teeth, thereby providing initial dental plaque removal.

  • Publication number: 20230009970
    Abstract: An apparatus and method for providing efficient power management for data transfer protocols between components. A source generates requests and a destination services the requests. The source and destination support a communication protocol that includes both a transfer channel and one or more transaction channels for each type of request. The source and destination rely on a valid signal and a ready signal of the transfer channels to autonomously manage power consumption. The source and destination remove any dependencies on an external power manager and make it unnecessary to add signal extensions to the communication protocol to support power management.
