22 A spatial light modulator (10) having reduced control circuitry as compared to existing devices. Sets of pixel elements (11) share a memory cell (12), such that each memory cell (12) has the same fanout as other memory cells (12). Each pixel element (11) in a set is switched to an on or off state via a reset line (13) that is separate from that of the other pixel elements (11) in that set. Frame data is loaded in split bit-frames during a set time period, such that each split bit-frame contains only the data for pixel elements (11) on one reset line (13). Thus, the same memory cell (12) can be used to deliver data to all pixel elements (11) in its fanout because only one pixel element (11) in the fanout is switched at a time.
