Abstract:
1. A display comprising: a planar array of transmissive liquid crystal display (LCD) devices; and a plurality of laser diode devices including at least a laser diode emitting in the red portion of the visible spectrum, a laser diode emitting in the green portion of the visible spectrum, and a laser diode emitting in the blue portion of the visible spectrum spaced apart from the planar array of LCD devices and configured to sequentially illuminate at least a subset of the LCD devices of the planar array of LCD devices such that, in operation, the plurality of laser diode devices provides backlighting for the subset of LCD devices of the planar array of LCD devices while the subset of LCD devices sequentially generates color-separated images corresponding to the respective colors of the laser diode devices; wherein at least one of the plurality of laser diode devices generates a beam of light having a divergence angle, and wherein the display panel further comprises a beam spreader configured to increase the divergence angle of the beam of light.
