A display system comprises line buffer memory that stores input image data in a first color space, and a plurality of gamut mapping modules that accept the input image data from the line buffer memory and performs a gamut mapping operation to produce mapped image data specified in a second color space. The system also includes a subpixel rendering module that renders the image data specified in the second color space for display on a display panel substantially comprised of a particular subpixel repeating group. The system architecture utilizes a plurality of gamut mapping modules which in turn allows for a reduction in the size of line buffer memory needed for the subpixel rendering operation.
