Abstract
Techniques are described for operating a display system comprising a light source, a scanning assembly, and a controller. The light source includes a plurality of emitters arranged in a column. The scanning assembly includes a reflective surface. A control signal including linear or sinusoidal pulses is applied to cause the reflective surface to rotate. The controller drives the emitters in sequence, using a same image data value, and in synchronization with the rotating of the reflective surface such that light emitted by different emitters of the plurality of emitters is reflected onto a same pixel of an output image. Changes in rotational speed are compensated for through increasing an emission duration for a first row driven while the reflective surface is rotating at a slower rotational speed, relative to an emission duration for a second row driven while the reflective surface is rotating at a faster rotational speed.
