摘要： A method includes generating a plurality of beams that each illuminate a separate portion of a spatial light modulator. The spatial light modulator has a first dimension of a first length and a second dimension of a second length. Each of the beams spans a portion of the first length of the first dimension and a portion of the second length of the second dimension. The method also includes scrolling the plurality of beams along the second dimension of the spatial light modulator while maintaining at least a first gap between each of the plurality of beams.

摘要： A method for increasing intensity resolution (bit-depth) using LED illumination. A preferred embodiment comprises determining a display time for a bit to be displayed on a display system, with the display time being based upon a weighting of the bit. If the display time is less than a minimum display time of the display system, then a light modulator and light source modulation are to be used to display the bit. If the display time is equal to or greater than the minimum display time, then a light modulator is to be used to display the bit. The use of a light source that can switch at a faster rate than the light modulator can change states and/or a light source that can produce light at multiple intensities can permit the display of less light and thereby increase the bit-depth of the display system.

摘要： A spoke synchronization technique allowing for lamp-pulsing synchronizes a spoke based on sub-arrays of a spatial light modulator. The lamp pulsing occurs during the spoke synchronization; and the lamp pulse for pulsing the lamp spans substantially across the entire spoke synchronization time period.
