Abstract:
1. A method for operating an electronic device having a spatial light modulator (SLM), the SLM having a plurality of light modulators, the method comprising: altering a spatial relationship between the 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, wherein the shifting is proportional to an amount of the altering performed on the spatial relationship; and placing a third portion of light modulators in the SLM into a performance degradation-reducing mode in which the degradation of the performance of the third portion of light modulators in the SLM is reduced; wherein the third portion of light modulators comprises light modulators illuminated by the light prior to the altering the spatial relationship but not illuminated by the light after the altering the spatial relationship; and wherein the third portion of light modulators comprises a range of about less than one (1) percent to about 20 percent of the first portion of light modulators.
