1. A photoluminescence color display comprising:

  • a display panel comprising a plurality of red, green and blue pixel areas;

    an excitation source operable to generate excitation radiation for operating the display;

    a photoluminescence color-elements plate comprising at least one of;

    a first photoluminescence material corresponding to red pixel areas of the display that is operable to emit red light in response to said excitation radiation;

    a second photoluminescence material corresponding to green pixel areas of the display that is operable to emit green light in response to said excitation radiation; and

    a third photoluminescence material corresponding to blue pixel areas of the display that is operable to emit blue light in response to said excitation radiation; and

    a wavelength selective filter disposed between the color-element plate and the excitation source, the wavelength selective filter having a characteristic that allows the passage of excitation radiation and substantially prevents the passage of light generated by the photoluminescence materials.
