Patent ID: 8704847

Claim:
A display device having a display panel configured with a subpixel layout; the display device comprising: input circuitry for receiving input image data including image data that has not yet been subpixel rendered, as well as an image data subset of the input image data indicating a plurality of pre-subpixel rendered image data values in conformance with, and ready for display on, the subpixel layout of the display panel; a pre-subpixel rendering detection component for detecting an input image location of each of the plurality of pre-subpixel rendered image data values from among the image data that has not yet been subpixel rendered; a subpixel rendering component for performing a subpixel rendering operation on the input image data to produce subpixel rendered image data values in conformance with, and ready for display on, the subpixel layout of the display panel; and an output data selection component for selecting an output color data value for each output location on the display panel, the output data selection component selecting one of the subpixel rendered image data value and the pre-subpixel rendered image data value for each output location according to the input image locations detected by the pre-subpixel rendering detection component; wherein, after input to the display device, the input image data proceeds along a first image data path to the pre-subpixel rendering detection component and bypasses the subpixel rendering component, and the input image data proceeds along a second image data path to the subpixel rendering component and bypasses the pre-subpixel rendering detection component; and wherein the output data selection component is configured to receive the input image locations detected by the pre-subpixel rendering detection component from the first image data path, and to receive the subpixel rendered image data values from the second image data path.
