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 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.

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.
