1. A display system, comprising:
a display including a plurality of pixels;
a display table including a plurality of rows, each row of the display table including a sequence of bit-planes associated with one of a plurality of phase-shift values for each of the pixels in the display, each sequence of bit-planes including one or more groups of 1-values spaced apart from one another within the sequence of bit-planes by one or more groups of 0-values;
each of the one or more groups of 1-values having a respective number of bit-planes that is within one bit-plane of the respective number of bit-planes of each other group of 1-values;
each of the one or more groups of 0-values having a respective number of bit-planes that is within one bit-plane of the respective number of bit-planes of each other group of 0-values; and
for each sequence of bit-planes where:
a length of the sequence of bit-planes is a first length;
a number P represents the number of 1-values in a sequence of bit-planes associated with one of the plurality of phase-shift values; and
the number P of 1-values is greater than one and less than the first length minus 2,
the number of 1-values being distributed across a length of the sequence of bit-planes according to a spacing D that is determined as the first length divided by P; and
a display driver configured to apply a sequence of bit-planes to each of the plurality of pixels, the sequence of bit-planes for each of the plurality of pixels corresponding to one of the rows in the display table and the one of the rows in the display table being determined by a corresponding phase-shift value for each of the plurality of pixels.
