本发明涉及液晶介质，尤其是用于2D/3D显示切换开关的液晶介质以及包含该液晶介质的2D/3D显示切换开关。
背景技术
实现3D显示的方式可以分为戴眼镜式和裸眼式，具体实现方式及原理可从孔令胜等，中国光学与应用光学，第2卷，第2期，112-118页；许精益和黄乙白，光学工程，第九十八期；Nicolas S.Holliman，Neil A.Dodgson，Gregg E.Favalora和Lachlan pocket，Ieeetransactions on broadcasting，Vol.57，No.2，page 362-371中获知。裸眼3D显示的一个缺点是其在显示2D画面时(例如，文字)，由于分辨率不足，导致显示质量下降。解决这一问题较好的办法就是在柱透镜式3D显示方式的基础上，加上一个可控的2D/3D显示之间切换的液晶开关。这些可从Uehara，shin-ichi等，EP1394593B1；“Switchable lenticular based2D/3D displays(基于2D/3D显示的可切换透镜)”Dick K.G.de Boer等，SPIE-IS&T，Vol.6490，49000R；“Overview of 3D/2D switchable liquid crystal display technologies(2D/3D可切换液晶显示技术)”Byoungho Lee和Jae-Hyeung Park，Proc.Of SPIE Vol.7618，761806；“Switchable 2D/3D display-Solid Phase Liquid Crystal Microlens Array(可切换的2D/3D显示-固相液晶微透镜阵列)”J.Harrold，D.j.Wilkes和G.J.Woodgate中获知。然而，用于2D/3D显示之间切换的液晶开关中的液晶介质却尚未发现有提及。
因此，对于能够用于2D/3D显示切换开关的液晶介质，存在巨大的需求。
