Abstract
(EN) A pair of shutter glasses (20), comprising a first polaroid (24), a second polaroid (25), a normally white type liquid crystal panel (231) and a normally black type liquid crystal panel (232). The thickness of the normally black type liquid crystal panel (232) is not equal to the thickness of the normally white type liquid crystal pane (231). An optical compensation film (233) is provided between the first polaroid (24) and a liquid crystal layer of the normally black type liquid crystal panel (232) and/or between the second polaroid (25) and the liquid crystal layer of the normally black type liquid crystal panel (232), so as to compensate for the chromatic dispersion of the liquid crystal layer of the normally black type liquid crystal panel (232) in a dark state. Therefore, on one hand, the response time of the shutter glasses (20) can be shortened to reduce the cost of electricity consumption, and on the other hand, the 3D crosstalk can be reduced. Also disclosed is a 3D display system.
(FR) L'invention concerne une paire de lunettes à obturateur (20) comprenant un premier polaroid (24), un second polaroid (25), un écran à cristaux liquides de type normalement blanc (231), et un écran à cristaux liquides de type normalement noir (232). L'épaisseur de l'écran à cristaux liquides de type normalement noir (232) n'est pas égale à l'épaisseur de l'écran à cristaux liquides de type normalement blanc (231). Un film de compensation optique (233) est ménagé entre le premier polaroid (24) et une couche de cristaux liquides de l'écran à cristaux liquides de type normalement noir (232) et/ou entre le second polaroid (25) et la couche de cristaux liquides de l'écran à cristaux liquides de type normalement noir (232), de manière à compenser la dispersion chromatique de la couche de cristaux liquides de l'écran à cristaux liquides de type normalement noir (232) à l'état foncé. Ainsi, d'un côté, le temps de réponse des lunettes à obturateur (20) peut être raccourcie afin de réduire le coût de la consommation électrique, et d'un autre côté, la diaphonie 3D peut être réduite. L'invention concerne également un système d'affichage 3D.
(ZH) 一种快门眼镜（20），包括第一偏光片（24），第二偏光片（25），常白型液晶面板（231）和常黑型液晶面板（232）。常黑型液晶面板（232）的厚度不等于常白型液晶面板（231）的厚度。在第一偏光片（24）与常黑型液晶面板（232）的液晶层之间和/或第二偏光片（25）与常黑型液晶面板（232）的液晶层之间设置有光学补偿膜（233），以补偿常黑型液晶面板（232）的液晶层在暗态时的色散。从而一方面能够缩短快门眼镜（20）的反应时间，降低耗电成本，另一方面可以降低3D串扰。还公开了一种3D显示系统。
