Abstract
Disclosed herein are methods for providing a load/reset sequence for a visual display system (100) having a phased reset spatial light modulator (SLM) (14). The SLM (14) has pixels (21) that are addressable with data by means of loads (ld) and resets (r), where the data is formatted in bit-planes (0-14)and each bit-plane is loaded as one or more segments (S0-S5) in a predetermined sequence during a frame-time. In one embodiment, the method comprises storing a display order of the segments (S0-S5) and determining whether resetting any of the segments (S0-S5) conflicts with the resetting of another of the segments (S0-S5), thereby identifying a conflicting segment. The method further includes skewing the display time of the conflicting segment to avoid the reset conflict, and identifying in the sequence a segment before and a segment after the conflicting segment each affected by the skewing of the conflicting segment, where the segments before and after the conflicting segment are each of respective bit-planes comprising multiple segments in the sequence. In this embodiment, the method further comprises counter-skewing the display times of segments respectively corresponding to the …
