Title (EN) OPTOELECTRONIC DEVICE WITH LIGHT-EMITTING DIODES
(FR) DISPOSITIF OPTOÉLECTRONIQUE À DIODES ÉLECTROLUMINESCENTES
Abstract:
(EN) The invention relates toan optoelectronic device (10) comprising light-emitting components (16), each light-emitting component being adapted to emit a first radiation at a first wavelength, and photoluminescent blocks (32), each photoluminescent block facing at least one light-emitting component and comprising a single quantum well or multiple quantum wells (38), photoluminescent blocks being divided into first photoluminescent blocks adapted to convert by optical pumping the first radiation into a second radiation at a second wavelength, second photoluminescent blocks adapted to convert by optical pumping the first radiation into a third radiation at a third wavelength and third photoluminescent blocks adapted to convert by optical pumping the first radiation into a fourth radiation at a fourth wavelength.
(FR) L'invention concerne un dispositif optoélectronique (10) comprenant des composants électroluminescents (16), chaque composant électroluminescent étant conçu pour émettre un premier rayonnement à une première longueur d'onde, et des blocs photoluminescents (32), chaque bloc photoluminescent faisant face à au moins un composant électroluminescent et comprenant un puits quantique unique ou de multiples puits quantiques (38), des blocs photoluminescents étant divisés en premiers blocs photoluminescents conçus pour convertir par pompage optique le premier rayonnement en un deuxième rayonnement à une deuxième longueur d'onde, en deuxièmes blocs photoluminescents conçus pour convertir par pompage optique le premier rayonnement en un troisième rayonnement à une troisième longueur d'onde et en troisièmes blocs photoluminescents conçus pour convertir par pompage optique le premier rayonnement en un quatrième rayonnement à une quatrième longueur d'onde.
