Title: Runar Tornqvist: Innovator in Electroluminescent Technology
Introduction
Runar Tornqvist is a notable inventor based in Kauniainen, Finland. He has made significant contributions to the field of electroluminescent technology, holding 2 patents that showcase his innovative approaches to display components.
Latest Patents
One of his latest patents is a method of growing a ZnS:Mn phosphor layer for use in thin-film electroluminescent components. This invention involves growing the ZnS:Mn phosphor layer on a substrate using the ALE method with volatile zinc, sulfur, and manganese compounds as precursors. The method utilizes an organozinc compound, such as diethylzinc or dimethylzinc, for zinc, hydrogen sulfide or an organosulfur compound for sulfur, and an organomanganese compound for manganese. This invention results in a display component that exhibits drive-voltage-symmetrical light emission and stable characteristics of luminance level and turn-on voltage.
Another significant patent by Tornqvist is related to a thin-film matrix structure particularly suitable for electroluminescent displays. This structure includes a substrate capable of supporting the thin-film structure, a first electrode structure formed onto the substrate, and a luminescent multilayered thin-film structure. The second transparent electrode structure is formed on the luminescent multilayered thin-film structure, with elongated parallel electrode conductors aligned orthogonally to the first electrode structure. This innovative design reduces power consumption in electroluminescent displays.
