    摘要: 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.
