Abstract
(EN) The present application discloses a light modulation module and a switchable stereoscopic display apparatus. The light modulation module comprises: a first substrate and a second substrate that are arranged opposite to each other; a first driving layer and an optical structure layer which are disposed on the side of the first substrate close to the second substrate; a second driving layer which is disposed on the side of the second substrate close to the first substrate; and an electro-optical material which is disposed between the first driving layer and the second driving layer, wherein the orthographic projection of at least one of the first driving layer and the second driving layer on the plane where the light modulation module is located is strip-shaped.
(FR) La présente demande divulgue un module de modulation de lumière et un appareil d'affichage stéréoscopique commutable. Le module de modulation de lumière comprend : un premier substrat et un second substrat qui sont disposés à l'opposé l'un de l'autre ; une première couche d'entraînement et une couche de structure optique qui sont disposées sur le côté du premier substrat à proximité du second substrat ; une seconde couche d'entraînement qui est disposée sur le côté du second substrat à proximité du premier substrat ; et un matériau électro-optique qui est disposé entre la première couche d'entraînement et la seconde couche d'entraînement, la projection orthographique d'au moins l'une de la première couche d'entraînement et de la seconde couche d'entraînement sur le plan où se trouve le module de modulation de lumière étant en forme de bande.
