1. A device comprising:
- a two-dimensional array of light modulating elements;
a controller for reading pixel values for a one-dimensional array of light modulating elements of said two-dimensional array of light modulating elements; and
an array of processing elements for computing a one-dimensional array of control signals for output bits that control each of said light modulating elements, wherein said one-dimensional array of control signals is computed based on one or more sets of one-bit positions of said pixel values, wherein said control signals are used to control a next value of each of said output bits to thereby control each of said light modulating elements and wherein said next value can be conditionally set or reset.
