Described is a display system comprising a light source, a scanning assembly, and a controller. The light source includes a first plurality of emitters forming a column that emits a first color. The light source also includes a second plurality of emitters forming a column that emits a different color. The scanning assembly includes a reflective surface rotated by the controller using a control signal having a nonlinear, pulsed waveform. The controller drives the first plurality of emitters and the second plurality of emitters in sequence, during respective portions of the nonlinear waveform, and in synchronization with rotation of the reflective surface such that light emitted by the first plurality of emitters and the second plurality of emitters is reflected onto a same pixel of an output image. The controller also adjusts emission durations of individual emitters to compensate for changes in the rotational speed of the reflective surface.
