Abstract:
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: red quantum dots material corresponding to red pixel areas that is operable to emit red light in response to said excitation radiation; green quantum dots material corresponding to green pixel areas that is operable to generate green light in response to said excitation radiation; and blue quantum dots material corresponding to blue pixel areas that is operable to emit blue light in response to said excitation radiation; and a wavelength selective filter disposed between the color-elements 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 of the photoluminescence color-elements plate.
