Abstract
A system and method for operating an electronic device used in light processing. A method comprises altering a spatial relationship between a spatial light modulator (SLM) and a light incident on the SLM, shifting light modulator states of a first portion of light modulators to a second portion of light modulators, and placing a third portion of light modulators in the SLM into a performance degradation-reducing mode. The amount of shifting performed is proportional to the amount of change in the spatial relationship. The method allows for a change in light modulators used to modulate the light, thereby preventing the overuse of some of the light modulators, which may help to prevent degradation of the light modulators. The performance degradation reducing mode may help to further reduce or even reverse the performance degradation of the light modulators.
