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, wherein the light incident on the SLM arrives at the SLM through an injection optic and is collected by a collection optic, and wherein the altering the spatial relationship between the SLM and the light incident on the SLM comprises shifting the injection optic and the collection optic; 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.
