According to a feature of the present invention, a method is provided for using a two-dimensional matrix of light emitting elements to display an image electronically encoded in the form of illumination values. An array of elements including less than all of the elements in the matrix to display the image is defined. A sweep rate for writing the illumination values for the elements in the array is determined, and a sweep signal having the illumination values for the elements in the array is generated, where the sweep signal writes illumination values for the elements in the array at the determined sweep rate. According to another embodiment of the present invention, a display driver generates an image encoded in the form of illumination values. The driver includes an image source and a controller receiving the image from the image source, said controller being adapted to (1) define an array of elements including fewer than all of the elements in the matrix for display of the image (2) determine a sweep rate for writing illumination values to the array of elements, and (3) generate images by writing illumination values to the elements in the array at the sweep rate.
