Abstract: Methods and control systems are provided for displaying an image electronically encoded in the form of illumination values using a two-dimensional matrix of image elements, each element adapted to covert energy to emit the light when an illumination value is written thereto. In accordance with one method, an array of elements including less than all of the elements in the matrix are defined to display the image so that the amount of energy consumed by the elements of the matrix when displaying an image using the elements of the array is lower than the amount of energy that the elements of the matrix would consume in displaying the image using all of the elements of the matrix.
