    摘要： A patterned phosphor structure, and EL laminate containing same (10), forming red, green and blue sub-pixel phosphor elements (30) for an AC electroluminescent display. The patterned phosphor structure includes at least a first (30) and a second phosphor (22) emitting light in different ranges of the visible spectrum, but with combined emission spectra contains red, green and blue light, the first (30) and second phosphors (22) being in a layer, arranged in adjacent, repeating relationship to each other to provide a plurality of repeating first and second phosphor deposits. The phosphor structure also includes one or more means (25) associated with one or more of the first and second phosphor deposits, and which together with the first and second phosphor deposits, form the red (30a), green (30c) and blue (30b) sub-pixel phosphor elements, for setting and equalizing the threshold voltages, and for setting the relative luminosities. Also provided is an improved dielectric layer (16) for use in an EL laminate.
