Abstract[English]
Disclosed herein is a micro LED projector comprising at least two micro LED panels (201,202) emitting different color rays and a micro optical combination element (301); the micro LED panel comprises a micro LED array formed by multiple micro LEDs; and, the micro optical combination element (301) faces the emitting direction of the different color rays emitted from the micro LED panels (201,202), to combine the different color rays into a combined ray; wherein, the chief ray angles of the micro LEDs in the micro LED panel are different. The chief ray angle of the micro LED structure is controlled, the loss of the light emitting from the sidewall of the mesa is reduced, and the volume and the weight of the micro LED projector are further decreased.[French]
La présente invention concerne un projecteur à micro-DEL comprenant au moins deux panneaux à micro-DEL (201, 202) émettant différents rayons de couleurs et un élément de combinaison micro-optique (301) ; le panneau à micro-DEL comprend un réseau de micro-DEL constitué de multiples micro-DEL ; et l'élément de combinaison micro-optique (301) fait face à la direction d'émission des différents rayons de couleurs émis par les panneaux à micro-DEL (201, 202), afin de combiner les différents rayons de couleurs en un rayon combiné ; les angles principaux des rayons des micro-DEL dans le panneau à micro-DEL étant différents. L'angle principal du rayon de la structure à micro-DEL est réglé, la perte de la lumière émise par la paroi latérale de la mesa est réduite, et le volume et le poids du projecteur à micro-DEL sont encore diminués.
