1. An apparatus comprising:
a tri-linear microdisplay comprising a plurality of display pixels that define one or more stripes, wherein each of the one or more stripes comprises a plurality of rows of pixels of the plurality of display pixels;
a display driver including a data register configured to:
drive the plurality of display pixels of the tri-linear microdisplay to present one or more sub-bands of a particular image on one or more of the on or more stripes of the tri-linear microdisplay; and
scroll image lines of an image through the plurality of display pixels of the one or more stripes by loading image data of the image into the data register and the data register feeding the image data through each of the one or more stripes row by row;
whereby the apparatus is used in a 1D-scanning display system to create high-resolution images in an augmented reality (“AR”) or Head Mounted Display;
wherein the display driver is configured to achieve a pixel illumination by shifting the particular image through multiple rows such that the resulting perceived pixel illumination is the sum of the pixel intensities from the corresponding pixels in each row.
