技术领域
本发明属于立体显示领域，特别涉及一种裸眼3D立体显示技术。
背景技术
近年来，随着智能显示产品的不断普及和竞争的加剧，3D显示技术迅速发展，并且得到了长足的进步，现实产品越来越往轻薄化发展，受到3D领域技术研究人员的极大关注，同时，伴随着显示技术的革新，显示技术正在经历从平面到立体的过渡，然而立体显示技术中的裸眼3D立体显示技术已经成为显示领域新的发展趋势，越来越多的显示产品开始整合裸眼3D立体显示技术。人眼在看到实际物体时，由于两眼视距有一个细微的差距，导致我们看物体呈现立体状态，而我们所谓的3D显示技术就是让人从显示设备上看到的被拍摄的物体呈现实际物体的立体感，裸眼3D同样是利用两眼具有视差的特性，但是是利用技术手段让显示设备自然投射出两种不同效果的画面给左右眼，而无需观看者另行佩戴辅助装置，即可获得具有空间、深度的逼真立体影像。
现行的裸眼3D立体显示技术为：在底层基板上涂布胶体，通过模具压制形成凸透镜形状的透镜A2，将透镜A2贴合到显示屏A1上，形成裸眼3D透镜，该3D透镜的弊端在于只能处于3D显示，而不能在3D显示和2D显示之间进行随意切换，并且，生产过程复杂，生产成本高，智能化程度低，不利于立体显示的发展，产品质量不佳。
发明内容
针对上述现有技术中的问题，本申请提出一种裸眼3D透镜显示设备及该裸眼3D透镜显示设备的制作方法。

本发明所述两层电磁屏蔽膜中，一层电磁屏蔽膜的厚度为0.1mm～0.3mm，另一层电磁屏蔽膜的厚度为0.1mm～0.3mm，并且，两层电磁屏蔽膜的透光率均在95％以上。
本发明的透明磁性粒子为球体，且球体的外径为90nm～110nm。
本发明的边框及支撑柱的高度为15μm～25μm，其中高度指所述边框及支撑柱在垂直于所述电磁屏蔽膜的平面的方向上的幅度。
本发明的边框及支撑柱和两层电磁屏蔽膜组成多个封闭空间。
本发明的显示屏可以为OLED显示屏。
本发明的显示屏还可以为液晶显示屏。

制作步骤二、在一层带有多个电控磁极的电磁屏蔽膜上设置边框及支撑柱；
制作步骤三、在边框内部灌注含有透明磁性粒子的液体介质；
制作步骤四、边框及支撑柱与另一层带有多个电控磁极的电磁屏蔽膜进行对组，对组后完成对3D透镜的制作；
制作步骤五、3D透镜与显示屏进行对组。
本发明通过对多个电控磁极的电流控制，控制电控磁极的强弱，形成凹凸状磁场，使多个透明磁性粒子在液体介质中顺着磁场线方向呈现不同的排布方式，当多个透明磁性粒子在液体介质呈现的排布方式为弧形时，该裸眼3D透镜显示 设备为3D显示，当多个透明磁性粒子在液体介质呈现的排布方式为均匀同向时，该裸眼3D透镜显示设备为2D显示。因此，本发明的有益效果是该裸眼3D透镜显示设备能够在3D显示和2D显示之间进行随意切换；电磁屏蔽膜的使用，消除了外界磁场对电控磁极的影响，由于电磁屏蔽膜的透光率均在95％以上，所以该裸眼3D透镜的显示效果极佳；电磁屏蔽膜的厚度在0.1mm～0.3mm，并且，边框及支撑柱的高度为15μm～25μm，因此，该裸眼3D透镜显示设备整体上轻薄，成本低，智能化程度高，更有利于立体显示的发展。
