Abstract

La présente divulgation se rapporte au domaine technique des dispositifs d'affichage, et en particulier un procédé et un appareil de fabrication d'un dispositif d'affichage 3D à l'œil nu, et un équipement et un support de stockage. Le dispositif d'affichage 3D à l'œil nu comprend un rétroéclairage 2D, une plaque de guidage de lumière 3D et un premier substrat, qui sont disposés de manière séquentielle. Le procédé comprend : la fabrication d'un premier trou ou d'une première rainure sur un rétroéclairage 2D ; la fabrication d'un second trou ou rainure au niveau de la position d'une plaque de guidage de lumière en 3D qui correspond au premier trou ou à la première rainure ; et la fourniture d'un dispositif photosensible dans le premier trou ou la première rainure. Par conséquent, la largeur d'un cadre du dispositif d'affichage 3D à l'œil nu est réduite.
