Abstract
(EN)
An optical axis tunable liquid crystal lens (10) includes a liquid crystal layer (200); and a control electrode configured to adjust an optical axis of the optical axis tunable liquid crystal lens (10). The control electrode includes a first electrode (310) configured to be provided with a common voltage signal (Vc) and a second electrode (320) configured to be provided with a control voltage signal. The first electrode (310) is on a side of the liquid crystal layer (200) away from the second electrode (320). The second electrode (320) includes a first sub-electrode (321) and a second sub-electrode (322) spaced apart from each other and being on two opposite sides with respect to a center of the second electrode (320), the first sub-electrode (321) and the second sub-electrode (322) being independently addressable, the first sub-electrode (321) configured to be provided with a first voltage signal (V1) and the second sub-electrode (322) configured to be provided with a second voltage signal (V2).

L'électrode de commande comprend une première électrode (310) configurée pour être pourvue d'un signal de tension commun (Vc) et une seconde électrode (320) configurée pour être pourvue d'un signal de tension de commande. La première électrode (310) est sur un côté de la couche de cristaux liquides (200) à l'opposé de la seconde électrode (320). La seconde électrode (320) comprend une première sous-électrode (321) et une seconde sous-électrode (322) espacées l'une de l'autre et étant sur deux côtés opposés par rapport à un centre de la seconde électrode (320), la première sous-électrode (321) et la seconde sous-électrode (322) étant indépendamment adressables, la première sous-électrode (321) configurée pour être pourvue d'un premier signal de tension (V1) et de la seconde sous-électrode (322) configurée pour être pourvue d'un second signal de tension (V2).
