A light source for a 3D display system, said light source comprising: a first emitter (B1, G1, R1) operative to emit light having a first spectral distribution within a first color range, said first spectral distribution having a central wavelength and a particular full width at half maximum (FWHM); a second emitter (B4, G4, R4) operative to emit light having a second spectral distribution within said first color range, said second spectral distribution being spaced apart from said first spectral distribution; a third emitter (B2, G2, R2) operative to emit light having a third spectral distribution within said first color range, said third spectral distribution overlapping a portion of said first spectral distribution, being spaced apart from said second spectral distribution, having a central wavelength between said central wavelengths of said first spectral distribution and said second spectral distribution, and having a particular FWHM that is smaller than the FWHM of said first spectral distribution; and a fourth emitter (B3, G3, R3) operative to emit light having a fourth spectral distribution within said first color range, said fourth spectral distribution overlapping a portion of said second spectral distribution, being spaced apart from said third spectral distribution, having a central wavelength between said central wavelengths of said second spectral distribution and said third spectral distribution, and having a particular FWHM that is smaller than a FWHM of said second spectral distribution; wherein said FWHM of first spectral distribution is greater than or equal to 4 nanometers; and wherein said FWHM of third spectral distribution is less than or equal to 2 nanometers. a first emitter (B1, G1, R1) operative to emit light having a first spectral distribution within a first color range, said first spectral distribution having a central wavelength and a particular full width at half maximum (FWHM); a second emitter (B4, G4, R4) operative to emit light having a second spectral distribution within said first color range, said second spectral distribution being spaced apart from said first spectral distribution; a third emitter (B2, G2, R2) operative to emit light having a third spectral distribution within said first color range, said third spectral distribution overlapping a portion of said first spectral distribution, being spaced apart from said second spectral distribution, having a central wavelength between said central wavelengths of said first spectral distribution and said second spectral distribution, and having a particular FWHM that is smaller than the FWHM of said first spectral distribution; and a fourth emitter (B3, G3, R3) operative to emit light having a fourth spectral distribution within said first color range, said fourth spectral distribution overlapping a portion of said second spectral distribution, being spaced apart from said third spectral distribution, having a central wavelength between said central wavelengths of said second spectral distribution and said third spectral distribution, and having a particular FWHM that is smaller than a FWHM of said second spectral distribution; wherein said FWHM of first spectral distribution is greater than or equal to 4 nanometers; and wherein said FWHM of third spectral distribution is less than or equal to 2 nanometers.
