Title (EN) METHOD FOR OPERATING A LIGHT-EMITTING DEVICE
(FR) PROCÉDÉ POUR FAIRE FONCTIONNER UN DISPOSITIF ÉMETTEUR DE LUMIÈRE
(DE) VERFAHREN ZUM BETREIBEN EINER LICHTEMITTIERENDEN VORRICHTUNG
Abstract:
(EN) The invention relates to a method for operating a light-emitting device. The light-emitting device (1) comprises a plurality of pixels (P), and each pixel (P) comprises at least three sub-pixels (r, g, b) which are designed to emit light of different colors in pairs. In the case of at least some pixels (P), in order to provide a pure color which corresponds to the dominant wavelength of a selected sub-pixel (r, g, b) of the pixel (P), the selected sub-pixels (r, g, b) and at least one additional pixel (P) sub-pixel (r, g, b) which is designed to emit light of a different color are operated.
(FR) L'invention concerne un procédé pour faire fonctionner un dispositif émetteur de lumière, le dispositif émetteur de lumière (1) comprenant une pluralité de pixels (P), chaque pixel (P) comprenant au moins trois sous-pixels (r, g, b) qui sont conçus pour émettre par paires une lumière de couleur différente. Afin de permettre la représentation d'une couleur pure qui correspond à la longueur d'onde dominante d'un sous-pixel sélectionné (r, g, b) du pixel (P), le sous-pixel sélectionné (r, g, b) et au moins un autre sous-pixel (r, g, b) du pixel (P), qui est conçu pour émettre une lumière d'une autre couleur, sont activés, au moins pour certains pixels (P).
(DE) Es wird ein Verfahren zum Betreiben einer lichtemittierenden Vorrichtung angegeben, wobei die lichtemittierende Vorrichtung (1) eine Vielzahl von Pixel (P) umfasst, jedes Pixel (P) zumindest drei Subpixel (r, g, b) umfasst, die dazu eingerichtet sind, paarweise Licht unterschiedlicher Farbe zu emittieren, zumindest für manche Pixel ( P) zur Darstellung einer reinen Farbe, welche der dominanten Wellenlänge eines ausgewählten Subpixels (r, g, b) des Pixels (P) entspricht, das ausgewählte Subpixel (r, g, b) und zumindest ein weiteres Subpixel (r, g, b) des Pixels (P), das dazu eingerichtet ist, Licht einer andere Farbe zu emittieren, betrieben werden.
