1. A display device comprising:
one or more light emitters configured to emit light;
a first waveguide disposed with respect to said one or more light emitters to receive light from said one or more light emitters such that said light is guided therein by total internal reflection, said first waveguide configured to eject light guided within said first waveguide out of said first waveguide;
a first beamsplitter configured to selectively direct light of a first spectral distribution and a first color light along a first direction and a second spectral distribution along a second direction, said first beamsplitter disposed with respect to said first waveguide to receive said light ejected from said waveguide such that light of said first and second spectral distributions from said first waveguide are incident on said first beamsplitter and said light having said first and second spectral distributions are directed along respective first and second optical paths, said light of said first spectral distribution and first color being directed to a respective first spatial location at a distance from said first waveguide; and
a spatial light modulator disposed with respect to said first waveguide to receive said light ejected from said waveguide and modulate said light, said first beamsplitter disposed with respect to said spatial light modulator such that said modulated light is directed along said first and second optical paths and said light of said first color is directed to said first spatial location at a distance from said spatial light modulator,
wherein said one or more light emitters is configured to emit light having a spectral distribution that includes spectral components corresponding to said first and second spectral distribution directed along said respective first and second optical paths.
