Patents by Inventor Raymond Leerentveld

Raymond Leerentveld has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11984076
    Abstract: What is disclosed are methods of non-uniformity compensation for active matrix light emitting diode device (AMOLED) and other emissive displays. For each pixel, greyscale level offsets for a number of predetermined greyscale drive levels which produce a uniform flat field are determined and used to generate a correction function for the pixel.
    Type: Grant
    Filed: June 20, 2022
    Date of Patent: May 14, 2024
    Assignee: Ignis Innovation Inc.
    Inventors: Raymond Leerentveld, Daniel Hills, Samer Musa
  • Publication number: 20230136688
    Abstract: Systems and methods for compensating for degradation of pixels that include OLEDs, including generating and maintaining a stress history model for generating a drive level correction function including drive gain and drive offset which are functions of stress and which compensate the display.

  • Patent number: 11062675
    Abstract: Systems and methods for correcting non-uniformity and for compensating for display OLED degradation utilize a correction factors k for each pixel, which is modelled and tracked based on grey level and a pixel parameter, such as temperature and time. The correction factor k is used to correct image data provided to an OLED display. To improve display uniformity for active matrix organic light emitting diode devices (AMOLED) and other emissive displays the panel luminance is a based on operating temperature, whereby the aging effect on a compensation parameter is independent of temperature.
