ABSTRACT:
A first pixel of a pixel array of a microdisplay is driven with a first pulse having a duration determined on the basis of a value loaded into a counter. A second pixel of the pixel array is driven with a second pulse having a duration determined on the basis of (a) the value loaded into the counter and (b) a value stored in a register.
