Abstract:
1. A method for rendering image data on a display panel comprising at least a first set of subpixels of a first color and a second set of subpixels of a second color, the first color having a first brightness versus viewing angle performance measure and the second color having a second brightness versus viewing angle performance measure so as to introduce color error when an image is viewed on the display panel at an off-normal viewing angle, the method comprising: receiving image data indicating an image and comprising image data values in the first and second colors; determining a mapping from the image data values in the first and second colors in a single image data plane to the first set of subpixels and the second set of subpixels in a plurality of frames to be displayed on the display panel such that one of the first set of subpixels is substantially equal to an average of two neighboring image data values and one of the second set of subpixels is substantially equal to an average of two neighboring image data values and such that an average of a first image data value and a second image data value adjacent to the first image data value maps to a first subpixel in a first frame and an average of the second image data value and a third image data value adjacent to the second image data value maps to the first subpixel in a second frame; and outputting to the display a pulse train of on/off patterns for the first set of subpixels and the second set of subpixels over a predetermined number of frames to produce a desired average subpixel luminance.
