Abstract

L'invention concerne un dispositif de lumière blanche et son procédé de fabrication, dans lequel des DEL rouges (3), des DEL bleues (2) et des OLED vertes (3') sont utilisées. Les DEL rouges (3), les DEL bleues (2) et les OLED vertes (3') émettent ensemble de la lumière, et les lumières provenant de celles-ci sont mélangées pour produire de la lumière blanche. Les DEL rouges (3), les DEL bleues (2) et les OLED vertes (3') sont disposées sur le même support (6). Cette sorte de dispositif de lumière blanche, dans lequel les DEL coopèrent avec des OLED, utilise efficacement la caractéristique de l'efficacité d'éclairage élevée des OLED vertes pour se combiner aux DEL rouges et DEL bleues de façon à former un dispositif de lumière blanche ayant une efficacité d'éclairage élevée et un bon effet de mélange de lumière.
