附图说明
图1为本发明的实施例提供的一种显示装置的示意图；
图2为本发明的实施例提供的显示装置的双视挡板与其他部件的位置关系示意图；
图3为本发明的实施例提供的显示装置以及显示系统的观看效果示意图。
具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
根据本发明的一种总体上的发明构思，提供一种显示装置，包括依次设置的显示面板、双视挡板、上偏光片、下偏光片和背光源；其中，背光源发出的光经下偏光片、显示面板、上偏光片、双视挡板后出射；所述显示面板包括多个第一亚像素和多个第二亚像素，所述第一亚像素和第二亚像素相邻设置以及设置在相邻的两个亚像素之间的黑矩阵；其中，显示面板、双视挡板、上偏光片、下偏光片和背光源之间的位置关系满足下述关系：tanθ＝(H*P)/[H2-(B+A)(B+A+P)]，其中，H为双视挡板与显示面板发光点之间的距离；P为单个亚像素的宽度；B为两个相邻的亚像素之间的黑矩阵宽度，A为双视挡板边缘到黑矩阵边缘的距离，θ为观看者只能看到第一亚像素的图像或者只能看到第二亚像素的图像的最大范围的夹角。从而实现对于同一双视显示装置，不同的观看者只能看到不同的显示画面，实现信息数据的保密显示。
另外，在下面的详细描述中,为便于解释,阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下,公知的结构和装置以图示的方式体现以简化附图。
本发明的实施例提供一种显示装置，参照图1所示，该显示装置，包括显示面板1、双视挡板2、上偏光片3、下偏光片4和背光源5；其中，背光源5发出的光经下偏光片4、显示面板1、上偏光片3、双视挡板2后出射；显示面板1包括第一亚像素1A和第二亚像素1B以及设置在相邻的两个亚像素之间的黑矩阵1C。
如图2所示，其示出了根据本发明的显示装置的各部件之间的位置关系示意图。
其中，θ为观看者只能看到第一亚像素的图像或者只能看到第二亚像素的图像的最大范围的夹角，即，单视场的角度θ，此处的单视场角度是指，在该视场范围观看者只能看到第一亚像素的图像或者只能看到第二亚像素的图像，其中，显示面板、双视挡板、上偏光片、下偏光片和背光源之间的位置关系满足下述关系：
tanθ＝(H*P)/[H2-(B+A)(B+A+P)]，
其中，H为双视挡板与显示面板发光点之间的距离；P为单个亚像素的宽度；B为两个相邻的亚像素之间的黑矩阵宽度，A为双视挡板边缘到黑矩阵边缘的距离。
根据本发明的显示装置，在观看者处于裸眼情况下，如图3所示，观看者只能看见第一亚像素1A的图像，而不能看到第二亚像素1B的图像；当观看者带上与显示装置的上偏光片相匹配的偏光眼镜时，只能看见第二亚像素1B的图像而不同看见第一亚像素1A的图像，从而实现信息数据的保密显示。
这里，与显示装置的上偏光片相匹配的偏光眼镜是指，如果上偏光片为左旋极性，则偏光眼镜为左旋极性；如果上偏光片为右旋极性，则偏光眼镜为右旋极性。
再参考附图1和2，根据本发明所提供的显示装置，双视挡板2设置在上偏光片3上，双视挡板开口的中心线与两个相邻的第一亚像素1A和第二亚像素1B的中心线是重合的，在单视场角度θ范围内，观看者只能考到第一亚像素1A的图像。
在本发明的实施方式中，上偏光片仅在对应的第二亚像素1B留空或没有偏光特性。本领域技术人员可以对本发明的实施方式进行修改，例如，上偏光片仅在对应的第一亚像素1A留空或没有偏光特性；再例如，改变上偏光片或下偏光片的偏光特性，上述修改都在本发明的范围内。
如图3所示，根据本发明的实施方式所提供的显示装置和显示系统，在裸眼情况下，观看者从单视场的角度只能看见第一亚像素1A的图像，不能看到第二亚像素1B的图像；当观看者带上偏光特性与上偏光片向匹配的偏光眼镜时，只能看见第二亚像素1B的图像，而不能看见第一亚像素1A的图像，从而实现信息数据的保密显示。
在本发明的实施方式中，在本发明的一个实施方式中，双视挡板为视差光栅，当挡板开口宽度为B+2A时.角度θ就是单视场的角度，在这个范围内，观看者只能看到点状亚像素所发出的光。结合像素的亚像素留空或没有偏光特性，实现同一显示屏幕，不同观看者只能看到不同的显示画面，实现信息数据的保密显示。
在本发明的一个实施方式中，双视挡板为柱状棱镜结构，当每个柱状棱镜覆盖两个子像素时，由于柱状棱镜的折射作用，可实现相同的单视场角度，在这个范围内，观看者只能看到点状亚像素所发出的光，结合像素的亚像素留空或没有偏光特性，实现同一显示屏幕，不同观看者只能看到不同的显示画面，实现信息数据的保密显示。
上述特征不是对双视挡板的限定，本领域技术人员也可以采用其他的结构或部件作为视差挡板。
在本发明的一个实施方式中，上偏光片为左旋极性，下偏光片为右旋极性或者下偏光片为左旋极性，上偏光片为右旋极性。如果上偏光片的偏光特性为左旋极性，则根据本发明的显示系统，其偏光眼镜设置成左旋极性。如果上偏光片的偏光特性为右旋极性，则根据本发明的显示系统，所述偏光眼镜设置为右旋极性。
如图1或2所示，在本发明的一个实施方式中，上偏光片对第一亚像素和第二亚像素中的其一留空或者没有偏光特性。
根据本发明所提供的显示装置和显示系统，针对同一显示设备，其实现了不同观看者只能看到不同的显示画面，从而实现了信息数据的保密显示。其适用于军事、商业等保密显示应用。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
