Abstract
A spatial light modulator (SLM) (20) having a pixel array (21) and a memory cell array (21a). Drivers (23c, 24b, 26, 27, 28) for the memory cell inputs permit pixels (10) of the SLM (20) to be addressed at a higher voltage than the voltage used for peripheral control circuitry (22, 23, 24). Each driver (23c, 24b, 26, 27, 28) has appropriate logic for providing an input signal to the memory cell array (21a) and a voltage translator (60) for changing the voltage level of that signal.
