Abstract
A pixel array structure for populating the display area of a display device includes a repeated first pixel group that consists of one or more first colored subpixels, three or more second colored subpixels and two or more third colored subpixels. The respective numbers of the first colored subpixels, the second colored subpixels, and the third colored subpixels that are provided within the first pixel group are in a respective ratio of 1:3:2. In one embodiment, an input RGB image is remapped to have luminance values corresponding to Cyan-Magenta-Yellow coordinates and the latter are used in combination with subpixel rendering (SPR) to drive the colored subpixels of the pixel array structure.
Claims20
A display device having a display area tessellated by a repeat group of minimal size among repeat groups that can be deemed to be populating the display area in a tessellating manner, the minimal repeat group comprising:
- a first number of one or more first colored subpixels whose respective first color predominantly occupies a relatively short wavelength portion of the visible light spectrum;
- a second number of three or more second colored subpixels whose respective second color predominantly occupies a relatively intermediate wavelength portion of the visible light spectrum;
- a third number of two or more third colored subpixels whose respective third color predominantly occupies a relatively long wavelength portion of the visible light spectrum;
- wherein the third number is greater than the first number and less than the second number;
- wherein the relatively intermediate wavelength portion is interposed on the visible light spectrum between the relatively short wavelength portion and the relatively long wavelength portion.
A display apparatus comprising:
- a substrate;
- and
- a plurality of display elements disposed on the substrate and defining a plurality of differently colored subpixels distributed within a display area of the substrate,
- wherein the distribution of the subpixels within the display area is defined by a pixel array structure that includes one or more first pixel groups, each of the first pixel groups including:
- a first colored subpixel and a second colored subpixel disposed along a first column;
- another second colored subpixel and a third colored subpixel disposed along a second column adjacent to the first column;
- and
- another third colored subpixel and yet another second colored subpixel disposed along a third column adjacent to the second column,
- wherein respective populations of the first colored subpixels, the second colored subpixels, and the third colored subpixels as included in the first pixel group are in a respective ratio of 1:3:2.
