随着触摸平板电脑的普及，用户对显示器的要求越来越高。现有的部分平板电脑能够实现裸眼立体显示，例如，每一亚像素列101所显示的视点图像通过光栅102而进入人眼，但如图1中所示，第一亚像素列所显示的第一视点图像在第一视角区域可见，该第一视角区域为由A11线和A12线限定的灰色阴影区域，第二亚像素列所显示的第二视点图像在第二视角区域可见，该第二视角区域为由A21线和A22线限定的圆点显示区域，第三亚像素列所显示的第三视点图像在第三视角区域可见，该第三视角区域为由A31线和A32线限定的即竖线区域，其中，1为第一亚像素单元，2为第二亚像素单元，3为第三亚像素单元，然而由于第一视角区域、第二视角区域以及第三视角区域的距离非常近，且视角范围局限在180度范围内，因此，各个视点图像之间存在串扰，无法实现多人利用一个显示器进行观看。
发明内容
本发明实施例提供了一种基板、光栅以及显示面板，通过基板上亚像素的排列方式，提升了观看每一视点图像的视角，且由于每一观看视角只能观看到该视角所对应的视点图像，从而降低不同视点图像之间的串扰。
一方面，本发明的实施例提供了一种基板，包括多个周期性排列的亚像素组，其中，每一亚像素组包括：用于显示多个视点图像的第一类亚像素组，所述第一类亚像素组包括：用于显示第一视点图像的第一亚像素单元、用于显示第二视点图像的第二亚像素单元以及用于显示第三视点图像的第三亚像素单元；所述每一亚像素组至少包括：第一亚像素列和第二亚像素列；所述第一亚像素单元位于所述每一亚像素组的第一亚像素列，所述第二亚像素单元与所述第三亚像素单元位于所述每一亚像素组的第二亚像素列，所述第二 亚像素列与所述第一亚像素列相邻，且与所述第一亚像素列在竖直方向错开预设距离，所述预设距离小于一个亚像素单元的宽度。
另一方面，本发明的实施例提供了一种与上述的基板相对应的光栅，所述光栅的开口区域与第一类亚像素组相对应，且该光栅的开口区域的形状为：由三角形和四边形组合而成的形状，其中三角形和四边形的一个边重合；或者，两个三角形组合而成的形状，其中一个三角形的顶点与另一三角形的一个边重合。

本发明实施例提供了一种基板、光栅以及显示面板，通过改变基板上亚像素的排列方式，增加了观看每一视点图像的视角，且由于每一观看视角区域只能观看到该视角区域所对应的视点图像，从而将不会受其他观看视角区域显示的视点图像的影响。

本发明的实施例提供了一种基板，包括多个周期性排列的亚像素组，其中，每个亚像素组包括多个亚像素单元，每一亚像素组包括：用于显示多个视点图像的第一类亚像素组。

参见图2，本发明实施例一提供了一种基板，当该基板中的每一亚像素组包括多个显示多个视点图像的第一类亚像素组，每个第一类亚像素组包括三个第一类亚像素单元时，也就是，该第一类亚像素组的每个包括：用于显示第一视点图像的第一亚像素单元201、用于显示第二视点图像的第二亚像 素单元202以及用于显示第三视点图像的第三亚像素单元203，第一亚像素单元、第二亚像素单元以及第三亚像素单元在该基板上的示例性排列如下：
所述第一亚像素单元201位于第一亚像素列，所述第二亚像素单元202与所述第三亚像素单元203位于第二亚像素列；
所述第一亚像素单元201与所述第二亚像素单元202相邻，且与所述第三亚像素单元203也相邻；
其中，如图2所示，第一亚像素列为斜线填充的亚像素列，第二亚像素列与第三亚像素列为横线填充的亚像素列。
其中，所述第二亚像素列与所述第一亚像素列相邻，且与所述第一亚像素列在竖直方向错开预设距离d，所述预设距离d小于一个亚像素单元的宽度e。
为增大各个观看视角的范围，所述每一亚像素组还可以包括：用于显示预设灰度值的第二类亚像素组。其中，参见图3a，当所述第二类亚像素单元预设的灰度值为零时，即第二类亚像素单元为黑色亚像素单元301时，可相应的增大视点图像的观看视角；参见图3b，当所述第二类亚像素单元预设的灰度值为最大时，即第二类亚像素单元为白色亚像素单元302时，可增加观看的环境光，降低能量损失。
示例性地，参见图3a以及图3b，当所述第二类亚像素组包括一个第二类亚像素单元，即第五亚像素单元时，在每个亚像素组中，第一亚像素单元、第二亚像素单元、第三亚像素单元以及第五亚像素单元在该基板上的示例性排列如下：

其中，如图8所示，第一亚像素列为斜线填充的亚像素列，第二亚像素列与第三亚像素列为横线填充的亚像素列，第三亚像素列为竖线填充的亚像素列。
其中，第二亚像素列位于第一亚像素列与第三亚像素列之间，且第二亚像素列与第一亚像素列在竖直方向错开预设距离d，同样，所述第二亚像素列与所述第三亚像素列在竖直方向错开同样的预设距离d，所述预设距离d小于一个亚像素单元的宽度e。
本发明实施例提供的第一亚像素单元、第二亚像素单元、第三亚像素单元以及第四亚像素单元的排列方式并不局限于实施例二中的排列方式。例如，第一类亚像素组可包括：第一亚像素组、第二亚像素组、第三亚像素组以及第四亚像素组，其中，第一亚像素组中包括多个第一亚像素单元，第二亚像素组中包括多个第二亚像素单元，第三亚像素组中包括多个第三亚像素单元，第四亚像素组中包括多个第四亚像素单元，第一亚像素组位于第一亚像素列，第二亚像素组与第三亚像素组位于第二亚像素列；第四亚像素组与第一亚像素组相邻，且与所述第三亚像素组也相邻。或者，本发明实施例二提供的基板的每个亚像素组还包括第二类亚像素组，该第二类亚像素组包括多个第二类亚像素单元，例如，当第二类亚像素组包括第五亚像素单元以及第六亚像素单元时，第一亚像素单元、第四亚像素单元与第五亚像素单元位于第一亚像素列；第二亚像素单元、第三亚像素单元与第六亚像素单元位于第二亚像素列；第五亚像素单元位于第一亚像素单元与第四亚像素之间，第六亚像素单元位于与第二亚像素单元与第三亚像素单元之间。
因此，根据图8所示的亚像素组，得到本发明实施例二提供的基板，参见图9。通过图9的亚像素单元的排列方式，可实现在第一视角观看到第一视点图像，在第三视角观看到第三视点图像，在第二视角观看到第二视点图像，在第四视角观看到第四视点图像。观看视角的区域可参见图10a与图10b，其中，1001为亚像素单元，1002为光栅，图10a中斜线区域为第一视角，图10a中灰色区域为第三视角，图10b中斜线区域为第二视角，图10b中灰色区域为第四视角。

综上所述，本发明的实施例提供了一种基板、光栅以及显示面板，增加了观看每一视点图像的视角，且由于每一观看视角只能观看到该视角所对应的视点图像，从而不会受其他观看视角显示的视点图像的影响；通过使每一亚像素组包括多个用于显示多个视点图像的亚像素单元，从而增大了不同方向的视点图像的观看视角，通过针对每一亚像素组分别增设了只显示灰度，不显示视点图像的第二类亚像素单元，从而降低了不同方向观看显示图像时出现的图像串扰现象。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
