  • 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: 11967570
    Abstract: A semiconductor package includes a base comprising a top surface and a bottom surface that is opposite to the top surface; a first semiconductor chip mounted on the top surface of the base in a flip-chip manner; a second semiconductor chip stacked on the first semiconductor chip and electrically coupled to the base by wire bonding; an in-package heat dissipating element comprising a dummy silicon die adhered onto the second semiconductor chip by using a high-thermal conductive die attach film; and a molding compound encapsulating the first semiconductor die, the second semiconductor die, and the in-package heat dissipating element.

  • 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.

  • Patent number: 11953751
    Abstract: A housing structure including a first housing and a second housing is provided. The first housing includes a first body and at least one metal fixing part protruding from the first body. The second housing includes a second body and at least one receiving part. The at least one metal fixing part leans against the at least one receiving part in a bent manner, such that the first housing is fixed on the second housing.

  • Publication number: 20060077799
    Abstract: A DVD device with video playback has a spindle motor to rotate a disc by a pick-up head. An integrated control unit includes a processor, MPEG interface, and I/O interface. The integrated control unit outputs control signals to a motor servo and a pick-up head servo so as to individually control the spindle motor and the pick-up head. The processor help a decoder to modulate the information marks into digital signals. Those digital signals are stored in a memory for forming a decompressed format to output and play. The integrated control unit integrates all the circuits, such as processor, in the DVD device into one chip or a single module to simplify components and the volume.

  • Patent number: 5903279
    Abstract: A modified three-pixel antialiasing method wherein the closest pixel from a displayed line has a constant display intensity includes the steps of locating a first pixel having a shortest distance along an axis of the pixel matrix array from the line, determining the shortest distance, calculating pixel intensity for the first pixel by multiplying a maximum intensity of the first pixel with a constant value, locating a second pixel having a second shortest distance along the axis from the line, locating a third pixel having a third shortest distance along the axis from the line, calculating pixel intensity for the second pixel, and calculating pixel intensity for the third pixel.
