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 (.DELTA..lamda.) and
a measured shift in one of a voltage across at least one of said
light-emitting elements (6R,6G) at a predetermined current (I.sub.s) and
a current through at least one of said light-emitting elements (6R,6G),
at a predetermined voltage (V.sub.s), 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.
