Abstract: This disclosure relates to various implementations improve operational lifetime for a spatial light modulator device. One or more controllers are able to determine a target duty cycle based on an operating condition for a spatial light modulator device. The spatial light modulator device comprises one or more light modulation components that modulate light. The controllers allocate a refresh time period for encoding spatial light modulator refresh instructions based on the target duty cycle and encode spatial light modulator refresh instructions within the refresh time period. Afterwards, the controllers transmit the spatial light modulator refresh instruction to the spatial light modulator device.
