Claim 0:
1. A method for controlling voltages of a liquid crystal on silicon (LCoS) two-dimensional array, wherein the LCoS two-dimensional array comprises a plurality of pixel sets, the plurality of pixel sets comprising a first pixel set and a second pixel set, the method comprising:
determining a plurality of bit sequences, the plurality of bit sequences comprising a first bit sequence and a second bit sequence;
controlling a voltage of the first pixel set by using the first bit sequence; and
controlling a voltage of the second pixel set by using the second bit sequence, wherein the first pixel set and the second pixel set are in different phase cycles in a port direction of the LCoS two-dimensional array, the first pixel set and the second pixel set having a same phase, and duty ratios of the first bit sequence and the second bit sequence being the same.
