摘要： A photoluminescence color display comprises a display panel that displays red, green and blue pixel areas, an excitation source operable to generate excitation radiation for operating the display, and a photoluminescence color-element plate. The color-element 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 pixel areas of the display in response to said excitation radiation. Additionally, the photo-luminescence color display comprises a wavelength selective filter that is provided between the color-element plate and the excitation source. The filter has a transmission characteristic that allows the passage of excitation radiation from the excitation source to excite the at least one photoluminescence material whilst preventing the passage of photoluminescence light back to the excitation source thereby prevent cross contamination of light among the different pixel areas of the display.
