Subpixel rendering filters for high brightness subpixel layouts

In a display comprising a subpixel repeating group, said subpixel repeating group comprising at least one white subpixel and a plurality of colored subpixels, wherein colors of said subpixels define a second color space, a method for rendering input image data of a first color space onto said display of said second color space, the steps of said method comprising:

• receiving input image data for rendering on said display;
• converting said input image data from said first color space to image data of said second color space;
• subpixel rendering each individual color plane of said image data of said second color space to produce subpixel rendered image data;
• and
• sharpening the subpixel rendered image data with a luminance signal.
