<p>A colour display device at least comprising a light source emitting at least two primary wavelengths; an array of holographic lenses (LH); and a spatial light modulator (LCD) comprising one pixel per holographic lens, where each pixel comprises one subpixel per wavelength to be displayed. Each holographic lens scatters and focuses each of the various wavelengths in one subpixel. This design requires only one lens for the various wavelengths. The device is useful for colour displays.</p> |
