摘要： A white-light electro-luminescent lamp having an adjustable spectral power distribution, including a first light-emitting element which emits light within each of three wavelength bands, 1) between 440 and 520 nm, 2) between 520 and 600 nm, and 3) between 600 and 680 nm. A second light-emitting element emits light within each of three wavelength bands, 1) between 440 and 520 nm, 2) between 520 and 600 nm, and 3) between 600 and 680 nm. A controller modulates the integrated spectral power of the light produced by the first and the second light-emitting elements such that the spectral power distribution of the light formed by combining the light produced by the modulated first and second light-emitting elements is substantially equal to a CIE standard daylight spectral power distribution for correlated color temperatures between 4000K-9500K.

摘要： A white-light electroluminescent device having an adjustable color temperature substantially on a predetermined range of a Planckian locus within the 1976 Commission Internationale de l'Eclairage (CIE) uniform chromaticity scale diagram. According to one embodiment, a first light-emitting element having a fixed ratio of at least two different species of emitters combined to produce a set of chromaticity coordinates at a predetermined white point substantially on the Planckian locus. A second light-emitting element having at least a single species of emitters produces a set of chromaticity coordinates. The set of chromaticity coordinates are positioned along a projected line extending from the Planckian locus and through the chromaticity coordinates of the first light-emitting layer. A controller adjusts the voltage or current associated with the first and second light-emitting elements to provide white light with a predetermined range of chromaticity coordinates substantially on the Planckian locus.

摘要： A full-color, light-emitting display device has improved efficiency with a large color gamut. The full-color, light-emitting display device has a plurality of pixels, each pixel having four or more colors of light-emitting elements. Three of the colors of light-emitting elements emits red, green, and blue light, and at least one of the colors of light-emitting elements emitting light is perceived to be within the gamut defined by the chromaticity coordinates of the red, green, and blue colored light-emitting elements. The light-emitting elements for emitting red, green, and blue colors of light each comprise a different species of inorganic light-emitting particles for emitting a different color of light. Each of the red, green, and blue species produces light having an emission spectrum with a full-width, half-maximum of less than or equal to 70 nm.
