| 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 (6R,6G), wherein said method comprises the steps of: inputting a data signal (S) comprising information to be displayed by said light-emitting elements (6R,6G), generating, in a correction means (10), a correction factor for each light-emitting element (6R, 6G), 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 (6R,6G) at a predetermined current (Is) and a current through at least one of said light-emitting elements (6R,6G), 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 (6R, 6G). The invention also relates to a drive means implementing the above-described method. |
