Abstract
Embodiments relate to driving first light emitting diodes (LEDs) of a first color to emit light during first subframes of emission frames, driving second LEDs of a second color to emit light during second subframes of emission frames, and driving third LEDs of a third color to emit light during the second subframes of emission frames. Light emitted from the first, second, and third LEDs is directed onto a mirror that reflects the light onto a plurality of pixel locations of an image field. The first, second, and third LEDs are aligned on an array of LEDs such that the first LEDs are at a first distance away from the second LEDs, and the first LEDs are at a second distance away from the third LEDs.
