1. A driver controller for a light modulation device,a look-up table (LUT) to store a plurality of binary sequences, each binary sequence corresponding to a target phase response of a pixel of a liquid crystal structure of the light modulation device;

  • wherein at least one binary sequence includes at least one pattern of binary values from among a plurality of patterns of binary values, the patterns of binary values comprising;

    a first set of patterns, each pattern of the first set of patterns generated as;

    for n=N−

    1 . . . 1, n leading “

    0”

    s plus a trailing “

    1”

    ;

    where n is an index ranging from 1 to N, and N represents a number of target phase responses; and

    a second set of patterns, each pattern of the second set of patterns generated as;

    for n=1 to N−

    2, generate pattern {01x}, where x=n number of trailing “

    1”

    s; and

    pixel electrode control circuitry to receive data having N target phase responses for at least one pixel and to determine a binary sequence of the LUT that matches a target phase response of the data;

    the pixel electrode control circuitry also to cause a first voltage level, corresponding to a first binary value of a binary sequence, to be applied to an electrode of the pixel, and to cause a second voltage level, corresponding to a second binary value of a binary sequence, to be applied to the electrode of the pixel.
