  • Patent number: 11832473
    Abstract: An opto-electronic device comprises light transmissive regions extending through it along a first axis to allow passage of light therethrough. The transmissive regions may be arranged along a plurality of transverse configuration axes. Emissive regions may lie between adjacent transmissive regions along a plurality of configuration axes to emit light from the device. Each transmissive region has a lateral closed boundary having a shape to alter at least one characteristic of a diffraction pattern exhibited when light is transmitted through the device to mitigate interference by such pattern. An opaque coating may comprise at least one aperture defining a corresponding transmissive region to preclude transmission of light therethrough other than through the transmissive region(s).

  • Patent number: 11793033
    Abstract: Apparatuses, systems, and methods are described to enhance images rendered on an Organic Light Emitting Diode (OLED) display. An OLED device is formed with a first light emitting OLED stack, a charge generating layer (CGL), a second light emitting OLED stack, and a color filter. An OLED display pixel includes three sub-pixels where each subpixel is fabricated with a separate anode and a color filter. A dielectric barrier is disposed between the separate anodes and around the perimeter of each separate anode of the three sub-pixels. When current flows to a desired sub-pixel of the three sub-pixels, lateral current flow through the CGL to adjacent sub-pixels is impeded, resulting in light generation by the desired sub-pixel and reduction in unwanted light generation at sub-pixels adjacent to the desired sub-pixel. The OLED device can include micro lenses, which collimate light thereby reducing an aperture of emitted light to increase display brightness.
