具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。

通常，多数立体显示装置均采用竖屏设计，但是实际观看立体图像时需要将产品旋转90度，即横屏观看立体图像，因此像素的方向也旋转了90度。但是立体显示装置中的3D光栅与黑矩阵图形平行排列，从而在显示时容易产生摩尔纹。
实施例一
图1为本实施例提供的一种显示装置的结构示意图，如图1所示，该显示装置包括显示面板11和位于显示面板11上方且沿第一方向设置的3D光栅，3D光栅包括多个依次设置的光栅单元12(图1中相邻两个黑色斜线所覆盖的区域为一个光栅单元所在的位置)，显示面板包括多列像素111；第一方向和像素的列方向具有设定夹角，该设定夹角为如图1所示的α，设定夹角α为非零值(α不为零)。例如，第一方向和像素的列方向不平行或不重合。例如，相邻两个光栅单元12相邻接。
沿第一方向设置的3D光栅是指每个光栅单元沿第一方向延伸设置，比如，若光栅为狭缝光栅，则狭缝光栅的遮光区和透光区均沿第一方向延伸。该第一方向为图1中靠左的箭头所示的方向。
α为非零值，例如，α可以为10度至40度，进一步例如，α可以为10度至20度。
显示装置中的每列像素均包括沿列方向(如图1中所示的纵向)排列的多个像素111，每个像素111包括至少三个沿列方向依次排列的子像素，如包括红色子像素R、绿色子像素G和蓝色子像素B。
本实施例中以每个像素111包括红色子像素R、绿色子像素G和蓝色子像素B为例说明。在实际应用中，每个像素111中的子像素的数量和颜色均不限于图1中所示，每个像素111中的子像素的数量可以为其它数量且子像素的颜色可以为其它颜色，此处不再一一列举。
例如，一个示例提供的显示面板中，像素排列方式可以为：各列像素周期性重复排列，各列像素中的第n个像素完全对齐，使得每列像素的第n个子像素构成一行子像素。
例如，另一个示例提供的显示面板中，像素排列方式还可以是如图1所示的方式。如图1所示，每个像素包括至少三个沿列方向依次排列的子像素， 奇数列像素和偶数列像素在列方向上错开设定距离，该设定距离小于或等于一个子像素在列方向的长度。
例如，一个示例中，显示面板11还包括黑矩阵(图1中未示出)，黑矩阵呈纵横交错形式排列。因此当3D光栅的第一方向与像素的列方向具备设定夹角时，3D光栅的第一方向与黑矩阵之间也具备一定的夹角，即，3D光栅与黑矩阵的延伸方向之间为非平行。
例如，上述显示装置可为立体显示装置。例如，该立体显示装置可以为裸眼3D显示装置。
本实施例对显示面板的类型不作限定，例如，显示面板可以包括液晶显示面板和/或发光二极管显示面板等。
本实施例提供的任一显示装置中，显示面板上方设置有沿第一方向排列的3D光栅，第一方向和像素的列方向具有设定夹角且设定夹角为非零值，因此倾斜的3D光栅与黑矩阵图形之间不再平行设置，从而减少了显示时产生的摩尔纹。
实施例二
图2为本实施例提供的一种显示装置的结构示意图。如图2所示，该显示装置包括显示面板11和位于显示面板11上方且沿第一方向设置的3D光栅，3D光栅包括多个依次设置的光栅单元12。显示面板包括多列像素111。第一方向和像素的列方向具有设定夹角α，设定夹角α为非零值。
每个光栅单元12之间平行设置。且每个光栅单元12也沿第一方向设置。该第一方向为图2中标示光栅单元12的实线所指向的方向。
图3为图2中像素排列的示意图，如图3所示，本实施例中，奇数列像素和偶数列像素在列方向上错开设定距离L，设定距离L小于或等于一个子像素在列方向的长度。图1中，以第1列像素和第2列像素为例，第1列像素和第2列像素在列方向上错开一个子像素在列方向的长度的1/2。
如图2所示，显示面板被划分为间隔设置的第一视图像素区和第二视图像素区，第一视图像素区中的子像素显示第一视图，第二视图像素区中的子像素显示第二视图。图2中“1”表示第一视图，“2”表示第二视图，则图2中标识“1”的子像素可形成第一视图像素区，标识“2”的子像素可形成第二视图像素区。第一视图和第二视图中的其中之一为左眼视图，另一为右眼视图， 在此不做具体限定。
图4为图2中光栅单元的示意图，如图3所示，光栅单元12的栅距P＝[D/(D+d)]×S，其中，P为光栅单元12的栅距，S为n个子像素在行方向上的长度和，D为人眼与显示面板11之间的距离，d为光栅单元12与显示面板11之间的距离，n为正整数。栅距例如为一个光栅单元12在垂直于第一方向上的宽度。本实施例的一示例中，n为2至9，采用上述参数可使得显示装置获得较佳的观看视角和3D显示效果。从上述公式可以看出，光栅单元12的栅距小于n个子像素在行方向上的长度和。例如，d＝0.415mm，P＝0.09443mm，n＝3，S＝0.0945mm，D＝380.876mm，采用上述参数可以使得显示装置获得最佳的观看视角和3D显示效果。
设定夹角α可以为10度至40度。本实施例的一示例中，设定夹角α为10度至20度，采用上述角度可以减少摩尔纹。例如，设定夹角α为12.1度至13.22度，采用上述角度减少或避免摩尔纹的效果更佳。进一步，例如，设定夹角α为13.19度或12.11度，采用上述角度可以在保证显示装置显示时立体感的前提下减少摩尔纹，也就是说，采用上述角度可以使得保证立体感和减少摩尔纹的综合效果最佳。以图2中像素11的列方向为基准，本实施例中3D光栅向左倾斜设置；在实际应用中3D光栅还以向右倾斜，此种情况不再具体画出。
例如，3D光栅20可以为狭缝式光栅、透镜式光栅等。
图6为图2中3D光栅为狭缝式光栅的局部结构示意图，图6中以一个光栅单元12为例进行说明，如图2和图6所示，3D光栅为狭缝式光栅时，光栅单元12包括间隔设置的遮光区和透光区，遮光区和透光区覆盖第一视图像素区和第二视图像素区。即，透光区的中心线对应于第一视图像素区和第二视图像素区的交界线，该交界线可以为光栅单元12的中心线(图2中光栅单元12中的虚线)。例如，透光区的中心线在显示面板11上的投影与第一视图像素区和第二视图像素区的交界线重合。每个光栅单元12可覆盖相邻的第一视图像素区和第二视图像素区。每个光栅单元12中，透光区在行方向上的宽度M1和遮光区在行方向上宽度(M2+M3)的宽度比为1:1至1:4，采用上述宽度比可使得显示装置获得较佳的3D显示效果。如图2所示，一个示例中，每个光栅单元12中，透光区在行方向上的宽度M1和遮光区在行方向 上的宽度(M2+M3)的宽度比为1:3，采用上述宽度比可使得显示装置获得最佳的3D显示效果。
如图2所示，3D光栅可为透镜式光栅，每个光栅单元12覆盖相邻的第一视图像素区和第二视图像素区。
本实施例中，每六列子像素形成一个像素组，像素组重复排列。下面以一个像素组为例对显示装置的显示过程进行详细描述，该像素组包括从左侧开始的第1列像素至第6列像素。
第1列像素中，第1个子像素至第3个子像素显示第一视图，第4个子像素至第12个子像素显示第二视图，第13个子像素至第22个子像素显示第一视图。接下来9个子像素显示第二视图，再接下来10个子像素显示第一视图，依此类推直至该列结束。即：最初3个子像素显示第一视图；接下来9个子像素显示第二视图，再接下来10个子像素显示第一视图，依此类推直至该列结束。
第2列像素中，第1个子像素至第10个子像素显示第一视图，第11个子像素至第19个子像素显示第二视图。接下来10个子像素显示第一视图，再接下来9个子像素显示第二视图，依此类推直至该列结束。即：最初10个子像素显示第一视图；接下来9个子像素显示第二视图，再接下来10个子像素显示第一视图，依此类推直至该列结束。
第3列像素中，第1个子像素至第6个子像素显示第二视图，第7个子像素至第16个子像素显示第一视图，第17个子像素至第25个子像素显示第二视图。接下来10个子像素显示第一视图，再接下来9个子像素显示第二视图，依此类推直至该列结束。即：最初6个子像素显示第二视图；接下来10个子像素显示第一视图，再接下来9个子像素显示第二视图，依此类推直至该列结束。
第4列像素中，第1个子像素至第3个子像素显示第一视图，第4个子像素至第13个子像素显示第二视图，第14个子像素至第22个子像素显示第一视图。接下来10个子像素显示第二视图，再接下来9个子像素显示第一视图，依此类推直至该列结束。即：最初3个子像素显示第二视图；接下来10个子像素显示第二视图，再接下来9个子像素显示第一视图，依此类推直至该列结束。
第5列像素中，第1个子像素至第9个子像素显示第一视图，第10个子像素至第19个子像素显示第二视图，第20个子像素至第28个子像素显示第一视图。接下来10个子像素显示第二视图，再接下来9个子像素显示第一视图，依此类推直至该列结束。即：最初9个子像素显示第一视图；接下来10个子像素显示第二视图，再接下来9个子像素显示第一视图，依此类推直至该列结束。
第6列像素中，第1个子像素至第7个子像素显示第二视图，第8个子像素至第16个子像素显示第一视图，第17个子像素至第26个子像素显示第二视图。接下来9个子像素显示第一视图，再接下来10个子像素显示第二视图，依此类推直至该列结束。即：最初7个子像素显示第二视图；接下来9个子像素显示第一视图，再接下来10个子像素显示第二视图，依此类推直至该列结束。
综上所述，从图1可以看出，3D光栅的一个边缘和中心线之间形成第一视图像素区，该第一视图像素区中的子像素显示第一视图；3D光栅的另一个边缘和中心线之间形成第二视图像素区，该第二视图像素区中的子像素显示第二视图。且显示第一视图的子像素和显示第二视图的子像素交替设置。
本实施例中，第一视图像素区和第二视图像素区的临界区域中的子像素的亮度低于其他区域的子像素的亮度。例如，第一视图像素区和第二视图像素区的临界区域中的子像素的亮度与其他区域的子像素的亮度的比值小于80％且大于0。例如，第一视图像素区和第二视图像素区的临界区域中的子像素的亮度与其他区域的子像素的亮度的比值为50％。
如图2所示，第1列中相邻的第3个子像素和第4个子像素、相邻的第12个子像素和第13个子像素以及相邻的第22个子像素和第23个子像素均位于临界区域中，则第1列中相邻的第3个子像素和第4个子像素的亮度、相邻的第12个子像素和第13个子像素的亮度以及相邻的第22个子像素和第23个子像素的亮度均低于其他区域的子像素的亮度。第2列中相邻的第10个子像素和第11个子像素以及相邻的第19个子像素和第20个子像素位于临界区域中，则第2列中相邻的第10个子像素和第11个子像素的亮度以及相邻的第19个子像素和第20个子像素的亮度均低于其他区域的子像素的亮度。第3列中相邻的第6个子像素和第7个子像素、相邻的第16个子像素和第 17个子像素以及相邻的第25个子像素和第26个子像素位于临界区域中，则第3列中相邻的第6个子像素和第7个子像素的亮度、相邻的第16个子像素和第17个子像素的亮度以及相邻的第25个子像素和第26个子像素的亮度均低于其他区域的子像素的亮度。
如图2所示，第4列中相邻的第3个子像素和第4个子像素、相邻的第13个子像素和第14个子像素以及相邻的第22个子像素和第23个子像素位于临界区域中，则第4列中相邻的第3个子像素和第4个子像素的亮度、相邻的第13个子像素和第14个子像素的亮度以及相邻的第22个子像素和第23个子像素的亮度均低于其他区域的子像素的亮度。第5列中相邻的第9个子像素和第10个子像素以及相邻的第19个子像素和第20个子像素位于临界区域中，则第5列中相邻的第9个子像素和第10个子像素的亮度以及相邻的第19个子像素和第20个子像素的亮度均低于其他区域的子像素的亮度。第6列中相邻的第7个子像素和第8个子像素、相邻的第16个子像素和第17个子像素以及相邻的第26个子像素和第27个子像素位于临界区域中，则第6列中相邻的第7个子像素和第8个子像素的亮度、相邻的第16个子像素和第17个子像素的亮度以及相邻的第26个子像素和第27个子像素的亮度均低于其他区域的子像素的亮度。
本实施例中，第一视图像素区和第二视图像素区的临界区域中的子像素的亮度低于其他区域的子像素的亮度，有效减弱了临界区域的3D串扰，从而提升了3D显示效果。
例如，显示面板11还可包括黑矩阵图形，黑矩阵图形呈纵横交错形式排列。因此当3D光栅的第一方向与像素的列方向具备设定夹角时，3D光栅的第一方向与黑矩阵图形之间也具备一定的夹角。即：3D光栅与黑矩阵图形之间不平行。
例如，显示装置可为立体显示装置。例如，该立体显示装置可以为裸眼3D显示装置。
如图5所示，3D光栅20设置在显示面板11上，3D光栅的衬底基板201上设置有多个如上所述的光栅单元12。当然，也可以不设置衬底基板201，而是将光栅单元12设置在显示面板11上。此情况下，3D光栅可为狭缝式光栅。当3D光栅为透镜式光栅时，3D光栅还可以为上衬底基板和下衬底基板 之间夹设液晶层的结构，此情况下，可在上衬底基板上设置上电极，在下衬底基板上设置下电极以形成电场驱动3D光栅中的液晶层中的液晶形成透镜，例如形成柱透镜。
例如，本实施例提供的显示装置中，显示面板上方设置有沿第一方向排列的3D光栅，第一方向和像素的列方向具有设定夹角且设定夹角为非零值，因此倾斜的3D光栅与黑矩阵图形之间不再平行设置，从而减少了显示时产生的摩尔纹。
实施例三
本实施例提供了一种显示装置的驱动方法，该显示装置可采用上述实施例一或者实施例二提供的显示装置，显示面板被划分为间隔设置的第一视图像素区和第二视图像素区。该方法包括：在第一视图像素区中的子像素显示第一视图以及在第二视图像素区中的子像素显示第二视图。第一视图和第二视图中的其中之一为左眼视图，另一个为右眼视图。
例如，本实施例中，在第一视图像素区中的子像素显示第一视图以及在第二视图像素区中的子像素显示第二视图之前还包括：控制第一视图像素区和第二视图像素区的临界区域中的子像素的亮度低于其他区域的子像素的亮度；在第一视图像素区中的子像素显示第一视图以及在第二视图像素区中的子像素显示第二视图包括：第一视图像素区中的子像素根据控制后的亮度显示第一视图以及第二视图像素区中的子像素根据控制后的亮度显示第二视图。例如，控制第一视图像素区和第二视图像素区的临界区域中的子像素的亮度与其他区域的子像素的亮度的比值小于80％。例如，第一视图像素区和第二视图像素区的临界区域中的子像素的亮度与其他区域的子像素的亮度的比值为50％。
对显示装置的显示过程的具体描述可参见实施例二中的描述，此处不再赘述。
本实施例提供的显示装置的驱动方法中，显示面板上方设置有沿第一方向排列的3D光栅，第一方向和像素的列方向具有设定夹角且设定夹角为非零值，因此倾斜的3D光栅与黑矩阵图形之间不再平行设置，从而减少了显示时产生的摩尔纹。
本发明实施例提供的技术方案可以和人眼追踪技术相结合，通过人眼追 踪技术对人眼进行追踪得出追踪结果，根据该追踪结果可以实现对显示装置显示过程的操控。例如，当3D光栅为狭缝式光栅时，可根据追踪结果对透光区和遮光区进行操控。又例如，可根据追踪结果对第一视图像素区和第二视图像素区显示的视图进行操控，例如，可根据追踪结果操控第一视图像素区显示第二视图以及操控第二视图像素区显示第一视图，或者，根据追踪结果操控第一视图像素区显示第一视图以及操控第二视图像素区显示第二视图。综上所述，本发明实施例提供的技术方案和人眼追踪技术相结合，可以有效提升显示装置的观看角度，从而提高了观看舒适度。
本发明的实施例具有以下有益效果：
本发明的实施提供的显示装置及其驱动方法中，显示面板上方设置有沿第一方向排列的3D光栅，第一方向和像素的列方向具有设定夹角且设定夹角为非零值，因此倾斜的3D光栅与黑矩阵图形之间不再平行设置，从而减少了显示时产生的摩尔纹。
在不冲突的情况下，本发明的同一实施例及不同实施例中的特征可以相互组合。
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。
