摘要： The invention relates to an electroluminescent composition comprising an electroluminescent material containing an aryl vinylene and an additive for suppressing a drop in the initial efficiency of light emission observed when the electroluminescent material is used as such in an electroluminescent device. The invention further relates to an electroluminescent composition comprising an electroluminescent material containing an aryl vinylene and an additive, wherein the additive comprises an oligo ring structure with at least four carbonyl groups and to an electroluminescent device comprising the composition according to the invention.

摘要： This invention relates to a method for color correction in an organic electroluminescent device ( 1 ), having at least one pixel ( 6 ), comprising an electro-luminescent material layer ( 5 ), which is sandwiched between a first and a second electrode ( 2, 3 ), and constituting at least a first and a second light-emitting element ( 6 R, 6 G), wherein said method comprises the steps of: inputting a data signal (S) comprising information to be displayed by said light-emitting elements ( 6 R, 6 G), generating, in a correction means ( 10 ), a correction factor for each light-emitting element ( 6 R, 6 G), said correction factor being based on a relationship between a color point wavelength shift (Deltalambda) and a measured shift in one of a voltage across at least one of said light-emitting elements ( 6 R, 6 G) at a predetermined current (I s ) and a current through at least one of said light-emitting elements ( 6 R, 6 G), at a predetermined voltage (V s ), applying said correction factor on said data signal (S), and supplying the corrected data signal (S) to the light-emitting elements ( 6 R, 6 G). The invention also relates to a drive means implementing the above-described method.
