  • 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.

  • 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.

  • Patent number: 10462924
    Abstract: A control system for mounting to a vertically-extending rail. The control system includes a plurality of bases, each having a channel formed therein that is adapted for mounting to the rail. A plurality of modules are provided for removable mounting to the bases, respectively. Each module has circuitry for processing control signals and a housing enclosing the circuitry. At least a bottom end of each housing has openings therein to permit air to flow into the housing and over the circuitry. A plurality of air flow deflectors are provided for mounting to the bases, respectively. When the modules and the air flow deflectors are mounted to the bases, the air flow deflectors form pockets with the bottom ends of the modules.

  • Patent number: 9176316
    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.

  • Patent number: 8717394
    Abstract: A method and system providing boundary dispersion to pixel values displayed on a binary spatial light modulator to reduce temporal contouring artifacts. Pixel code values are offset from a nominal value when displayed on the SLM to disperse a large bit transition for a pulse width modulation (PWM) system. The offset value varies as a function of the pixel digital code, the pixel spatial location on the screen, and pixel temporal location in time. The set of offsets applied to pixels is varied over a repeating sequence of 2 displayed frames.

  • Patent number: 8493419
    Abstract: A system and method for reducing pulse width modulation contouring artifacts. Each input intensity value is translated to at least one non-binary bit pattern for display. Many of the input intensity values are translated to at least two alternate non-binary bit patterns. The alternate codes are used to smooth the transition between intensity codes as major bits are turned on. The smoothing occurs by the gradual transition from codes that do not use the major bit to codes that do use the major bit. Typically the alternate codes are selected based on the location of the pixel in a spatial pattern (100) and the alternate codes are spatially alternated from one pixel (102) to the next (104). Other embodiments temporally alternate the codes from one period—typically a frame period—to the next. Still other embodiments alternate the codes both spatially and temporally.

  • Patent number: 8493289
    Abstract: Scanning mirror based display system and method. A method comprises sampling a scanned light provided by a scanning mirror, converting the sampled scanned light into an electrical signal, analyzing the electrical signal to determine a position of the scanned light, and controlling the light source or the scanning mirror based on the analyzed electrical signal. The electrical signal based on the sampled scanned light may be used to ensure proper operation of the scanning mirror display system, such as determining failure of the scanning mirror, proper rendering of colors, determining whether the scanned light is following a desired scan path at a desired scan rate, and so forth.

  • Patent number: 8432339
    Abstract: In accordance with the teachings of the present invention, a system and method for increasing the bit-depth of a video display system using a pulse lamp are provided. In one embodiment, the method includes illuminating a digital micro-mirror device with a light source having a variable power supply, receiving a signal indicating the light output provided to the digital micro-mirror device by the light source should be reduced to a target level during a predetermined time period, reducing a power supplied to the light source by the variable power supply in response to the signal such that the light output of the light source is reduced to about a target level during the predetermined time period, displaying a least significant bit on the digital micro-mirror device during the predetermined time period, and decreasing a speed of a master clock controlling the digital micro-mirror device in response to the light output of the light source deviating below the target level during the predetermined time period.
