    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.

    摘要： The invention aims to provide a phosphor thin film eliminating a need for filters, having a satisfactory color purity, suited for RGB in full-color EL displays, enabling to simplify the manufacture process of full-color EL panels, and offering the advantages of minimized variation of luminance, increased yields, and reduced manufacture cost, a method for preparing the same and an EL panel.
    Such objects are achieved by a phosphor thin film formed of a matrix material comprising an oxysulfide consisting of at least one compound selected from rare earth thioaluminates, rare earth thiogallates and rare earth thioindates, in which oxygen is incorporated, the matrix material further containing an element serving as a luminescent center, a method for preparing the same, and an EL panel using the same.

    摘要： A method of deposition of a phosphor in a single-source sputtering process, in which the phosphor is selected from the group consisting of ternary, quaternary or higher thioaluminate, thiogallate and thioindate phosphors, and composites thereof, synthesized with cations selected from Groups IIA and IIB of the Periodic Table of Elements. The phosphor is of a pre-determined composition of elements. The method comprising sputtering in a hydrogen sulphide atmosphere from a single source composition so as to deposit a composition on a substrate. The composition of the targets of the single source has a relative increase in concentration of elements of the phosphor that have a lower atomic weight compared to other elements in said phosphor. The relative increase is controlled such that deposition of the pre-determined composition is effected on the substrate. Preferred phosphors are barium thioaluminate (BaAl2S4:Eu), and barium magnesium thioaluminates.

    摘要： A driving circuit for powering an electroluminescent display using energy recovered from a varying panel capacitance of the display. The driving circuit comprises a source of electrical energy; and a resonant circuit using the panel capacitance for receiving the electrical energy and in response generating a sinusoidal voltage to power the display at a resonance frequency which is substantially synchronized to a scanning frequency of the display. The resonant circuit uses a step down transformer to reduce the effective panel capacitance of the display in order to reduce its effect on the resonance frequency.
