Abstract[English]
Disclosed herein are a micro LED structure and a micro LED projector. The micro LED structure comprises: a mesa structure and a reflective structure; wherein, the rays emitted from the sidewall of the mesa structure can be reflected by the reflective structure toward outside. The present disclosure can control the chief ray angle of the micro LED structure and reduce the loss of the light emitting from the sidewall of the mesa structure.[French]
L'invention concerne une structure de micro-DEL et un projecteur à micro-DEL. La structure de micro-DEL comprend : une structure mesa et une structure réfléchissante, les rayons émis à partir de la paroi latérale de la structure mesa pouvant être réfléchis par la structure réfléchissante vers l'extérieur. La présente invention peut commander l'angle de rayon principal de la structure de micro-DEL et réduire la perte de la lumière émise à partir de la paroi latérale de la structure mesa.
