| description | 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 (Is) and a current through at least one of said light-emitting elements ( 6 R, 6 G), at a predetermined voltage (Vs), 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. |
