    Abstract: Described examples include a process that includes illuminating a spatial light modulator at a first illumination level during a first bit-plane and stopping illumination at a beginning of a second bit-plane subsequent to the first bit-plane. The process also includes resuming illumination after a settling period of the spatial light modulator at a second illumination level for a time period such that a total illumination energy during the second bit-plane is equivalent to an intended illumination energy for the second bit-plane at the first illumination level and stopping illumination at the second illumination level before a subsequent third bit-plane.

    Abstract: An improved spatial light modulation display system includes light sources for providing red, green, and blue light. A system controller includes functionality for controlling a color balance of the red, green, and blue light. A sensor is provided for sensing light from each of the light sources. The controller can detect a shift in color balance based on the intensity of light sensed by the sensor. If the sensor output indicates that the sensor is operating out of a desirable range, the spatial light modulator can modulate the light in order change the brightness of light sensed by the sensor. The modulation pattern can be varied until the sensor output is a specified value or within a specified range of values. In a preferred embodiment, the sensor is located to receive off-state light from the spatial light modulator so as to avoid obstruction of light used for displaying images.

    Abstract: A control circuit includes a sequencing circuit. The sequencing circuit is configured to, in a color cycle: transfer a first bit plane to a spatial light modulator (SLM) and transmit a first global reset signal to the SLM instructing the SLM to load data of the first bit plane to pixel sub arrays of the SLM. The sequencing circuit is also configured to, in the color cycle: transfer a second bit plane to the SLM, and transmit a second global reset signal instructing the SLM to load data of the second bit plane to a first pixel sub-array of the pixel sub-arrays and to load data of the first bit plane to a second pixel sub-array of the pixel sub-arrays.
