ABSTRACT:
A method of evaluating pulse width modulation patterns for a spatial light modulator display device. The method makes use of a light difference series function. This series function is obtained by representing on or off times of a display element as a light function. (FIG. 3). Two such light functions can be subtracted to compare two different patterns on the same display element (interframe) or to compare the same pattern on different display elements (intraframe). (FIG. 4). The result of the subtraction is a light difference function (FIG. 5), which can be expressed as a series function. Mathematical expressions using the series function correlate to various optical characteristics.
