  • Patent number: 11935480
    Abstract: Systems and methods are used to dim an emissive display such as an organic light emitting diode (OLED) display. A dimming level setpoint signal is received. At least one dimming process is selected from four dimming processes based on a magnitude of the dimming level setpoint signal. A first dimming process selects a subrange of pixel illumination levels from a range of pixel illumination levels. A second dimming process adjusts a VCOM voltage for the pixel array. A third dimming process selects between rolling shutter and global shutter. A fourth dimming process selectively utilizes one or more subpixels from an emissive display pixel based on the magnitude of the dimming level setpoint signal. The selected dimming process or processes are applied to the emissive display, there by dimming the display. The display can be an OLED display.

  • Patent number: 11839093
    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.
