Abstract:
A method for using a two-dimensional matrix of light emitting elements to display an image electronically encoded in the form of illumination values, the method comprising the steps of:a) defining an array of elements including less than all of the elements in the matrix to display the image; b) determining a pixel rate for writing the illumination values for the elements in the array; c) assembling the illumination values for the elements of the array into horizontal scan lines and generating a sweep signal including each scan line; and d) generating a sweep signal incorporating each of the scan lines wherein the sweep signal writes illumination values for the elements in the array at the determined pixel rate and wherein the number of elements in each horizontal row of the array is not the same and further comprising the step of determining a horizontal sweep rate for each scan line, wherein the horizontal sweep rate for each scan line is at least equal to the pixel rate divided by the number of illumination values in each horizontal scan line.
