  • Patent number: 11159773
    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.

  • Patent number: 11074074
    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.

  • Publication number: 20210185268
    Abstract: Example multi-channel display systems are disclosed. An example apparatus includes at least one processor to execute instructions to at least in response to determining that a first display controller is to provide at least a first portion of video data on a first channel, provide a first control signal to the first display controller instructing the first display controller to provide the at least the first portion of the video data on the first channel, and in response to determining that a second display controller is to provide at least a second portion of the video data on a second channel, provide a second control signal to the second display controller instructing the second display controller to provide the at least the second portion of the video data on the second channel, the second channel different from the first channel.

  • Publication number: 20200209642
    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.

  • Publication number: 20200112708
    Abstract: Example apparatus described herein include a first circuit configured to slice an input image frame into input image slices, the first circuit including first outputs configured to output the input image slices. Described example apparatus also include digital light processing controllers (DLPCs) including first inputs coupled to the first outputs, the digital light processing controllers configured to process the input image slices to produce output image slices, the digital light processing controllers including second outputs configured to output the output image slices. Described example apparatus further include a second circuit including second inputs coupled to the second outputs, the second circuit configured to combine the output image slices to generate image frame data to provide to an input of a digital micromirror device (DMD).
