ABSTRACT:
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.
