A display system (10) comprises a digital micromirror device (DMD) (24) controlled by a driver circuit (30) responsive to sequences of pulse width segments formed by a processor (31). The processor (31) increases the pixel brightness by actuating selected pulses such that within a first range of brightness levels between first and second pixel brightness boundaries, a first large-duration pulse element becomes actuated to reach the second pixel brightness boundary, and within a second range of pixel brightness levels between second and third pixel brightness boundaries, the first large duration pulse element remains actuated. Upon reaching the third pixel brightness boundary, a second large duration pulse element now becomes actuated with the first large duration pulse element remaining actuated. Forming the pulse width segments in this manner serves to reduce motion contouring.
