View Patent ↗Techniques and mechanisms for displaying an image with structures of a pixel array. In an embodiment, pixels of the pixel array each include three chrominance elements and a fourth luminance element. Of the four elements of a given pixel, a first subset of the elements are aligned along a first line, a second subset of the elements are aligned along a second line offset from the first line, and a third subset of the elements are aligned along a third line extending athwart the first line and the second line, wherein two of the elements are located on opposite sides of the third subset. In another embodiment, image data processing, for displaying an image with the pixel array, includes updating luminance parameters of a plurality of pixel data sets independent of any evaluation to update one or more types of chrominance parameters of the plurality of pixel data sets.
