<p>A display comprises a light source and an image display panel (2) disposed in an optical path from the light source. The light source comprises a primary light source (6) for illuminating a re-emission material (7) which comprises at least a first nanophosphor material for, when illuminated by light from the primary light source (6), re-emitting light in a first wavelength range different from the emission wavelength range of the primary light source. The image display panel (2) comprises a first filter (9G) having a first narrow passband or a first narrow absorption band, the first narrow passband or first narrow absorption band being aligned or substantially aligned with the first wavelength range. The combination of a narrow wavelength range emitted by the first nanophosphor material and the narrow passband or narrow absorption band of the filter, aligned with the wavelength range emitted by the first nanophosphor material, allows a display with high efficiency and a high NTSC ratio to be obtained.</p> |
