Abstract: A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. The illumination optics may include a red, green, and blue light sources. The fLCOS panel may produce image light by modulating a series of image frames onto illumination light. Control circuitry may control the illumination optics to produce the illumination light for each image frame in the series of image frames according to a green-heavy illumination sequence that includes first, second, and third time periods. The green light source may be active during each of the first, second, and third time periods. This may allow the green light source to be driven with a lower current density than the other light sources without significantly reducing image quality at an eye box. The lower current density may match the peak efficiency of the green light source, thereby minimizing power consumption by the display.
