    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.

    Abstract: A system includes: a spatial light modulator including pixel elements; and a controller coupled to the spatial light modulator. The spatial light modulator sets the pixel elements based on a modulation control signal. The controller is configured to: obtain an image; analyze the image to determine image attributes including a dynamic range metric; provide a control sequence responsive to the determined image attributes; and provide the modulation control signal to the spatial light modulator based on the control sequence. The modulation control signal reduces a number of bits used by the pixel elements relative to a default number of bits if the dynamic range metric is below a dynamic range threshold.

    Abstract: A controller includes a frame memory configured to store an image frame, a frame memory controller coupled to the frame memory and configured to obtain image data from the image frame. The image data is associated with a color component of the image frame. The controller also includes a dither noise mask generator configured to provide dither noise masks according to dither noise levels for the image data, and a bit plane generator coupled to the frame memory controller and the dither noise mask generator and configured to generate bit planes based on the dither noise masks for the image data.
