Zusammenfassung:	A backlight unit (22) for illuminating an LCD panel of an LCD display is disclosed. The backlight unit (22) comprises lamp clusters (34), each of which includes a blue fluorescent lamp (36), a green fluorescent lamp (38) and a red fluorescent lamp (40) which are separately controllable so that the blue, green and red colour intensities can be separately adjusted to adjust the overall colour tone of light emitted by the cluster (34). La présente invention concerne une unité de rétroéclairage (22) pour éclairer le panneau LCD d'un affichage à cristaux liquides. L'unité de rétroéclairage (22) comprend des ensembles de lampes (34) dont chacun comprend une lampe fluorescente bleue (36), une lampe fluorescente verte (38) et une lampe fluorescente rouge (40) qui peuvent être commandées séparément de sorte que les intensités des couleurs bleue, verte et rouge puissent être ajustées séparément pour ajuster la tonalité de couleur générale de la lumière émise par l'ensemble (34).
