Abstract

La présente invention concerne un appareil d'affichage, comprenant une première zone d'affichage et une seconde zone d'affichage adjacentes l'une à l'autre. La première zone d'affichage comprend une couche de pixel, une couche d'anode et une couche de structure optique. La couche d'anode comprend une anode réfléchissante et une partie de transmission de lumière. La couche de structure optique peut modifier le trajet de propagation d'un signal optique, de telle sorte que le signal optique n'est plus incident à l'anode réfléchissante, mais est incident à la partie de transmission de lumière. La transmittance de lumière de la partie de transmission de lumière est beaucoup plus grande que la transmittance de lumière de l'anode réfléchissante, ce qui permet d'améliorer la transmittance de lumière de la première zone d'affichage.
