Abstract
The present invention relates to a thin-film matrix structure particularly suitable for electroluminescent displays, said structure comprising a substrate (7) capable of supporting the thin-film structure to be fabricated, a first electrode structure (9) formed onto the substrate (1), said structure being comprised of elongated parallel electrode conductors, a luminescent multilayered thin-film structure (10, 11, 12) formed onto the first electrode structure (9), and a second, transparaent electrode structure (13, 14) formed on said luminescent multilayered thin-film structure (10, 11, 12), said second electrode structure comprising elongated parallel electrode conductors which are aligned essentially orthogonally to the electrode conductors of the first electrode structure (9). According to the invention, the first electrode structure (9) is formed as a layer of metallic or metal alloy composition, and each transparent electrode conductor (13) of the second electrode structure (13, 14) is provided with a narrow stripe (14) of high electrical conductivity, whereby said stripe in itself need not be transparent. The structure in accordance with the invention provides reduced power consumption.
