An optical display system and method selectively displaces delta triad pixels vertically. The first raster line of picture information is removed from the video signal, and each subsequent raster line of picture information (data) is displaced upward. Next, the entire picture is optically displaced down by a distance equal to one vertical pixel pitch placing the picture back in its original vertical position, but horizontal position of the pixels has changed. Thus picture information is displaced horizontally a distance equal to one and one half times horizontal pixel pitch. Odd pixel rows are displaced in one direction, and even pixel rows are displaced in the opposite direction. The technique can be used to double pixel density and, thus, resolution, in the horizontal direction by the selective shifting technique and coordination with the input video signals. Two views of a picture alternate at the frame rate fast enough to fuse them into a single image, and two successive frames are combined over time to act as a single super frame. This is time based multiplexing of a spatial pattern. Thus, a composite picture is formed using a strip pixel pattern with twice the horizontal pixel density of the original delta pattern. The triads in the first half of this super frame may partially overlap the triads in the second half of the super frame. This technique can be applied to either progressive or interlace scan formats.

[ I claim:] [1.]1. A method of displaying a colored image provided from a display having plural pixels, at least some of which are comprised of plural differently colored sub-pixels which are arranged in other than a vertical straight line, comprisingselectively optically shifting the apparent location of at least one of such differently colored sub-pixels into substantially a straight line relation with another of such differently colored sub-pixels, wherein said plural pixels are comprised of triads of differently colored sub-pixels, at least two of such differently colored sub-pixels of a given triad being in one line and a third differently colored sub-pixel of such triad being displaced from the first two, and wherein said selectively optically shifting comprises shifting the third differently colored sub-pixel to be in a substantially continuous row with the first two.
