A photoluminescence color display comprises a display panel comprising a plurality of pixels composed of red, green and blue sub-pixel areas; an excitation source operable to generate excitation radiation for operating the display, and a photoluminescence color-element plate. The plate comprises at least one photoluminescence material, such as a phosphor material or quantum dots, that is operable to emit light corresponding to red, green and blue sub-pixel areas of the display in response to said excitation radiation. Additionally, the photoluminescence color display can comprise a wavelength selective filter provided between the color-element plate and the excitation source. The filter has a transmission characteristic that allows the passage of excitation radiation to excite the photoluminescence material whilst preventing the passage of photoluminescence light back to the excitation source thereby prevent cross contamination of light among the different color sub-pixel areas of the display. |
