  • Generation of subpixel values and light source control values for digital image processing
    Patent number: 8228357
    Abstract: A display system (110) has a subpixel array (120) and a light source (140). In normal mode, image data (164) are processed by the display system to generate subpixel values (174) for the subpixels (130) and to generate a light source control value (BL) for the light source (140). In bypass mode suitable for testing new types of image-data processing, the subpixel values and the light source control value are generated by an external system (210) and are provided to the display system which is operated in bypass mode. The light source control value is not provided separately from the subpixel values but is encoded into some bits of the subpixel values for compatibility with older interfaces. The light source control value is encoded into the subpixel values' MSBs in case the subpixel values could be truncated. Other features are also provided.

  • System and method for improving sub-pixel rendering of image data in non-striped display systems
    Patent number: 7825921
    Abstract: The present application discloses a number of embodiments for the mapping of input image data onto display panels in which the subpixel data format being input may differ from the subpixel data format suitable for the display panel. Systems and methods are disclosed to map input image data onto panels with different ordering of subpixel data that the input, different number of subpixel data sets or different number of color primaries that the input image data.
