Claim One:
1. A method of pulse-width modulating frames of multi-bit frame data used by a spatial light modulator, having an array of pixel elements, comprising the steps of: dividing the time to display each frame of data into equal time units; dividing a frame of data into split bit-frames, each split bit-frame containing data for pixel elements connected to an associated reset line; delivering data representing said split bit-frame of data to memory cells, wherein each memory cell is connected to a set of said pixel elements and receives a data bit representing an on or off state of only one of its pixel elements; loading said pixel elements, by using each memory cell to apply a data signal representing the data bit received by that memory cell to its associated pixel elements; switching said pixel elements, by using a reset signal to change the state of all pixel elements connected to said reset line; repeating the above delivering, loading, and switching steps for each split bit-frame of data within a data frame.
