Pixel Tile Structures and Layouts

A method for creating an image rendering surface from a plurality of pixel tiles,

• wherein each pixel tile in the plurality of pixel tiles comprises a plurality of pixel lines with a plurality of sub-pixels, wherein each of the plurality of pixel tiles is configured to be placed such that the sub-pixels or pixels in the pixel tiles are arranged in a regular pattern to form the image rendering surface, wherein misalignments between the pixel tiles cause deviations of the sub-pixels or pixels from the regular pattern, and wherein a pixel tile level misalignment between two pixel tiles is measured as a difference between corresponding pixel lines located in the two pixel tiles, the method comprising:
• determining an overall displacement tolerance applicable to each pixel tile in a plurality of pixel tiles to be used as parts of the image rendering surface, wherein the overall displacement tolerance is one of a maximum value, an average value, a median value, and a statistic value among a plurality of measured pixel tile level misalignments that are generated when placing the pixel tiles to form the image rendering surface;
• generating, within the limits of the overall displacement tolerance, non-uniform displacements of sub-pixels or pixels in each pixel tile in the plurality of pixel tiles;
• and
• combining the plurality of pixel tiles to create the image rendering surface.
