具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
请参考图1至图3，本公开实施例提供一种像素结构，包括由亚像素构成的多个重复单元，每一所述重复单元包括四个不同颜色的亚像素，所述四个不同颜色的亚像素分成两组，每一组亚像素中均包括一长轴方向为第一方向的亚像素和一长轴方向为第二方向的亚像素，所述第一方向和第二方向垂直。
本公开实施例中，每一重复单元中的四个不同颜色的亚像素可以包括基本色亚像素和一补偿色亚像素，所述基本色亚像素可以为红(R)、绿(G)和蓝(B)亚像素，所述补偿色亚像素可以为白色亚像素(W)，也可以为品红、黄色、青色或绛紫色等颜色的亚像素，其中，当补偿色亚像素为白色亚像素时，由于白色亚像素的透过率较高，因此能够对整个显示面板的亮度进行补偿。当补 偿色亚像素为品红、黄色、青色或绛紫色等颜色的亚像素时，能够对整个显示面板的色域进行补偿。
本公开的以下实施例中，均以一个重复单元中包括红(R)、绿(G)、蓝(B)三个基本色亚像素，和一个白(W)色补偿色亚像素为例进行说明。
可选地，本公开实施例的亚像素的形状为四边形，进一步的，本公开实施例的亚像素的形状为矩形。
请参考图1，图1为本公开实施例的一亚像素的长轴和短轴的示意图，其中，该亚像素的长轴L与短轴S垂直，该亚像素在长轴L方向上的长度大于在短轴S方向上的长度。
常规的像素结构中，像素单元中的多个亚像素的长轴通常为同一方向，与常规的像素结构不同的是，本公开实施例的像素结构中的每一重复单元的四个亚像素不规则排列，四个亚像素分成两组，每一组均包括一个长轴方向为第一方向的亚像素，和一长轴方向为第二方向的亚像素，该种排列方式可以实现各个颜色的亚像素的均匀分布，显示颜色更均匀，且有利于虚拟显示采样区(采样区的概念将在下述内容中介绍)的设计，从而可以利用低的物理PPI设计输出高品质的图像。
可选地，本公开实施例中，一重复单元的每一组中的两亚像素呈L型或L型的镜像顺时针或逆时针翻转0°、45°、90°、135°或180°排列，例如，L型的图案为
Figure PCTCN2015072141-appb-000001
L型的镜像的图案为
Figure PCTCN2015072141-appb-000002
其中L型的图案逆时针翻转0°、45°、90°、135°和180°的图案分别为
Figure PCTCN2015072141-appb-000003
当然，在本公开的其他实施例中，一重复单元的每一组中的两亚像素也可以呈T型顺时针或逆时针翻转0°、45°、90°、135°或180°排列。
下面举例对本公开实施例的重复单元中的亚像素的排列方式进行说明。
可选地，所述第一方向为行方向，所述第二方向为列方向，每一所述重复单元的两组亚像素中，长轴方向为第二方向的两亚像素位于相邻列，且该长轴方向为第二方向的两亚像素在行方向上以错开预设距离的方式设置。请参考图2A，每一所述重复单元中，长轴方向为第一方向的两亚像素与长轴方向为第二方向的两亚像素均相邻，长轴方向为第一方向的两亚像素不相邻，上述排列方式可以保证每一重复单元中的四个亚像素尽量靠在一起。
可选地，所述第一方向为行方向，所述第二方向为列方向，每一所述重复单元中，长轴方向为第一方向的两亚像素位于相邻行，且该长轴方向为第一方向的两亚像素在列方向上以错开预设距离的方式设置。请参考图2B，每一所述重复单元中，长轴方向为第二方向的两亚像素与长轴方向为第一方向的两亚像素均相邻，长轴方向为第二方向的两亚像素不相邻，上述排列方式可以保证每一重复单元中的四个亚像素尽量靠在一起。
当然，除了图2A和图2B中示出的排列方式之外，重复单元中的四个亚像素也可以采用其他排列方式，在此不再一一举例说明。
可选地，所述多个重复单元在第三方向上重复排列，所述第三方向为行方向逆时针旋转45°的方向，或者所述第三方向为列方向逆时针旋转45°的方向。请参见图3，图3为所述第三方向为行方向逆时针旋转45°的方向时像素结构的示意图。从图3中可以看出，所述长轴方向为第一方向的亚像素在第三方向依次排列，所述长轴方向为第二方向上的亚像素也在第三方向依次排列，且长轴方向为第一方向的亚像素和长轴方向为第二方向的亚像素在与所述第三方向垂直的方向上交替排列。
可选地，所述长轴方向为第一方向的亚像素为第一颜色亚像素和第二颜色亚像素，所述长轴方向为第二方向上的亚像素为第三颜色亚像素和第四颜色亚像素，所述第一颜色亚像素和第二颜色亚像素在第三方向上交替排列，所述第三颜色亚像素和第四颜色亚像素在第三方向上交替排列，这样排列方式可以保证亚像素的分布较均匀，可以达到更好的显示效果。

本公开实施例还提供一种显示装置，包括像素结构以及驱动该像素结构的驱动装置，所述像素结构为上述实施例中所述的像素结构。
本公开还提供一种像素结构的驱动方法，所述像素结构为上述实施例中描述的像素结构，所述驱动方法包括以下步骤：
步骤S51：使各亚像素位置显示所需的基本色的颜色分量，其包括：使一亚像素位置附近的多个同颜色的基本色亚像素共同进行显示，通过该多个同颜色的基本色亚像素的平均作用使该亚像素位置显示所需的该颜色分量；
步骤S52：对各亚像素位置进行显示补偿，其包括：用一亚像素位置附近的多个补偿色亚像素的平均作用对该亚像素位置进行显示补偿。
其中，以上2步骤表示的是显示过程中要进行的2种操作，二者分别用于显示3基本色颜色的分量和显示补偿，因此这2个步骤在时间顺序上并无必然的先后关系。
可见，本实施例的方法中，是让每个亚像素所在的位置(而非每个亚像素)均显示需要的内容(即同时显示所需的3种基本色的颜色分量)，且每个亚像素位置的每种颜色分量均由该亚像素位置附近的多个相应颜色的基本色亚像素共同显示，通过各基本色亚像素的平均作用使该亚像素位置达到显示所需要颜色分量的效果。同时，本实施例中还用补偿色亚像素对各亚像素位置进行显示补偿，以改善显示效果。
当然，应当理解，由于本实施例中每个亚像素位置的内容是由多个亚像素共同显示(包括补偿)的，因此相应的，每个亚像素也不仅用于一个位置的显示，而是同时用于多个亚像素位置的显示。也就是说，对于任何一个亚像素，其要显示的内容也是根据其所对应的多个亚像素位置所要显示的内容的决定的。
本实施例的驱动方式的优点在于：
1：每个亚像素位置都能显示全部颜色分量(如红色亚像素R处也可显示出蓝色分量)，即每个亚像素位置都能显示完整内容，也就是说每个亚像素位置都相当于一个“像素”，这样其视觉效果上的分辨率大幅提高。
2：每个亚像素位置都被进行显示补偿，达到良好的显示效果。
3：每个亚像素位置显示的内容(包括补偿)均是其附近的多个亚像素的平均结果，因此其显示的颜色均匀、柔和，显示效果好。
4：本实施例的方法中以每个亚像素位置为基准进行显示，并相应计算其 附近的各亚像素所要显示的内容，因此其可直接计算每个亚像素所要显示的内容，运算量小，容易实现。
可选的，当一亚像素位置要显示与该位置的亚像素颜色相同的基本色的颜色分量(如红色亚像素R位置要显示的红色分量)时，该亚像素位置附近的多个同颜色的基本色的亚像素包括：该亚像素位置的该亚像素本身(必然为红色亚像素R)，以及该亚像素位置周围的多个该颜色的基本色的亚像素(红色亚像素R)。
而当一亚像素位置要显示与该位置的亚像素颜色不同的基本色的颜色分量(例如红色亚像素R的位置要显示绿色分量)时，该亚像素位置附近的多个同颜色的基本色亚像素包括：该亚像素位置周围的多个与要显示的颜色分量相同颜色的基本色的亚像素(绿色亚像素G)。也就是说，此时“附近的基本色亚像素”不包括该位置的亚像素(因其颜色不同)。
其中，根据需求的不同，上述“附近的基本色亚像素”的取法是多样的。
下面对如何确定亚像素位置附近的多个同颜色的基本色亚像素的子颜色分量的方法进行说明。
可选地，当一亚像素位置要显示与该位置的亚像素颜色相同的基本色的颜色分量时，所述使一亚像素位置附近的多个同颜色的基本色亚像素共同进行显示的步骤包括：分别采用该亚像素位置的该亚像素本身及该亚像素位置周围的多个该颜色的基本色亚像素各自对应的显示比例系数乘以该亚像素位置显示所需的该基本色的颜色分量，得到该亚像素位置的该亚像素本身及该亚像素位置周围的多个该颜色的基本色亚像素各自的子颜色分量；
当一亚像素位置要显示与该位置的亚像素颜色不同的基本色颜色分量时，所述使一亚像素位置附近的多个同颜色的基本色亚像素共同进行显示的步骤包括：分别采用该亚像素位置周围的多个与要显示的颜色分量相同颜色的基本色亚像素各自的显示比例系数乘以该亚像素位置显示所需的该基本色的颜色分量，得到该亚像素位置周围的多个与要显示的颜色分量相同颜色的基本色亚像素各自的子颜色分量；
其中，该亚像素位置附近的每一基本色亚像素的显示比例系数与该基本色亚像素与该亚像素位置之间的距离有关。
举例来说，当一亚像素位置要显示与该位置的亚像素(红色亚像素R)颜色相同的颜色分量(红色分量)时，
将该亚像素位置的红色亚像素R的显示比例系数(如0.76)乘以该亚像素位置显示所需的颜色分量Y，得到该亚像素位置的红色亚像素R的子颜色分量0.76Y；以及
将亚像素位置周围的8个红色亚像素R各自对应的显示比例系数(如周围的每一红色亚像素R的显示比例系数均为0.03)分别乘以该亚像素位置显示所需的颜色分量Y，得到该亚像素位置周围的多个该颜色的彩色亚像素各自的子颜色分量0.03Y。
可选地，当一亚像素位置的亚像素为补偿色亚像素时，该亚像素位置附近的多个补偿色亚像素包括：该亚像素位置的该亚像素本身，以及该亚像素位置周围的多个补偿色亚像素；
当一亚像素位置的亚像素不是补偿色亚像素时，该亚像素位置附近的多个补偿色亚像素包括：该亚像素位置周围的多个补偿色亚像素。
下面对如何确定亚像素位置附近的多个补偿色亚像素的子颜色分量的方法进行说明。
可选地，所述用一亚像素位置附近的多个补偿色亚像素的平均作用对该亚像素位置进行显示补偿的步骤包括：
当一亚像素位置的亚像素为补偿色亚像素时，所述用一亚像素位置附近的多个补偿色亚像素的平均作用对该亚像素位置进行显示补偿的步骤包括：分别采用该亚像素位置的该亚像素本身及该亚像素位置周围的多个补偿色亚像素各自对应的显示比例系数乘以该亚像素位置显示所需的该补偿色的补偿分量，得到该亚像素位置的该亚像素本身及该亚像素位置周围的多个该补偿色的补偿色亚像素各自的子补偿分量；
当一亚像素位置的亚像素不是补偿色亚像素时，所述用一亚像素位置附近的多个补偿色亚像素的平均作用对该亚像素位置进行显示补偿的步骤包括：分别采用该亚像素位置周围的多个补偿色亚像素各自的显示比例系数乘以该亚像素位置显示所需的该补偿色的补偿分量，得到该亚像素位置周围的多个该补偿色的补偿色亚像素各自的子补偿分量；
其中，该亚像素位置附近的每一补偿色亚像素的显示比例系数与该补偿色亚像素与该亚像素位置之间的距离有关。
本公开实施例中，可以将一亚像素位置周围的多个亚像素构成的区域称为该亚像素位置的采样区，该多个亚像素称为公用亚像素。

请参考图5，图5为本公开实施例一的重复单元中的绿色亚像素的采样 区的示意图，本实施例中，绿色亚像素R10L7位置用于显示绿色分量，其附近的多个同颜色的绿色亚像素包括：分别位于该绿色亚像素R10L7所在行的两侧且最靠近该绿色亚像素R10L7所在行相邻的三行中，八个最靠近该绿色亚像素R10L7的绿色亚像素(R9L4，R7L6，R5L8，R8L9，R11L10，R13L8，R15L6，R12L5)，该八个绿色亚像素也称为公用亚像素，该八个公用亚像素构成一个将该绿色亚像素围住的菱形采样区。在该采样区内的八个公用绿色亚像素与该位置的绿色亚像素R10L7共同进行信号输出，但是输出的位置点在绿色亚像素R10L7位置上。该种包括八个公用亚像素的四边形采样区的公用范围较大，因此图片中在连续画面的表现能力较强。
请参考图6和图8，图6和图8所示的实施例中，均是一亚像素位置要显示与该位置的亚像素颜色相同的基本色的颜色分量的情况，图6为本公开实施例一的重复单元中的蓝色亚像素的采样区的示意图，图8为本公开实施例一的重复单元中的红色亚像素的采样区的示意图，其中，蓝色亚像素R11L8和红色亚像素R9L8与图5中的绿色亚像素R10L7相同，均具有包括八个公用亚像素的采样区。
当然，当一亚像素位置要显示与该位置的亚像素颜色不同的基本色的颜色分量时，也可以采用上述图5、图6和图8中的采样区，举例来说，图5中的位于采样区中的白色亚像素R8L6位置也可以显示绿色分量，并采用图5所示的采样区中的八个绿色亚像素作为公用亚像素。
图7为本公开实施例一的重复单元中的白色亚像素的采样区的示意图，本实施例中，白色亚像素R10L8位置用于显示白色。其附近的多个补偿色亚像素包括：分别位于该白色亚像素R10L8所在列的两侧且最靠近该白色亚像素R10L8所在列相邻的五列中，八个最靠近该白色亚像素R10L8的白色亚像素，该八个白色亚像素也称为公用亚像素，该八个公用亚像素构成一个将该白色亚像素R10L8围住的菱形采样区。
当然，当一亚像素位置的亚像素不是白色亚像素时，其附近的多个补偿色亚像素也可以为如图7所示的采样区中的白色亚像素。举例来说，图7中的位于采样区中的红色亚像素R8L8位置也可以采用图7所示的采样区中的八个白色亚像素作为补偿亚像素。
在本公开的其他实施例中，亚像素的采样区还可以为其他形状，下面举例进行说明。
请参考图9，图9为本公开实施例二的重复单元中的绿色亚像素的采样区的示意图，本实施例中，绿色亚像素R10L7用于显示绿色分量，其附近的多个同颜色的绿色亚像素包括：位于该亚像素位置周围的三个绿色亚像素(R13L8，R15L6，R12L5)，该绿色亚像素R10L7与该三个绿亚像素(R13L8，R15L6，R12L5)组成一菱形。在该采样区内的绿色亚像素共同进行信号输出，但是输出的位置点在绿色亚像素R10L7位置上。该种包括三个公用亚像素的四边形采样区的面积相对较小，能够更加精确地确认虚拟位置。
请参考图10，图10为本公开实施例三的重复单元中的绿色亚像素的采样区的示意图，本实施例中，绿色亚像素R10L7用于显示绿色分量，其附近的多个同颜色的绿色亚像素包括：位于该像素位置周围的两个绿色亚像素(R13L8，R12L5)，该绿色亚像素R10L7与该两个绿色亚像素(R13L8，R12L5)组成一等边三角形；在该采样区内的绿色亚像素共同进行信号输出，但是输出的位置点在绿色亚像素R10L7位置上。该种包括两个公用亚像素的三角形采样区面积非常小，可用于在边界的采样，其能够达到精细图片边缘的效果。
请参考图11，图11为本公开实施例四的重复单元中的绿色亚像素的采样区的示意图，本实施例中，绿色亚像素R10L7用于显示绿色分量，其附近的多个同颜色的绿色亚像素包括：位于该像素位置周围的两个绿色亚像素(R12L5，R15L6)，该绿色亚像素R10L7与该两个绿色亚像素(R12L5，R15L6)组成一等腰三角形。在该采样区内的绿色亚像素共同进行信号输出，但是输出的位置点在绿色亚像素R10L7位置上。同样的，该种包括两个公用亚像素的三角形采样区面积非常小，可用于在边界的采样，其能够达到精细图片边缘的效果。
同样的，上述图9-图11中的采样区可用于一亚像素位置要显示与该位置的亚像素颜色不同的基本色的颜色分量时的情况，以及用于补偿色亚像素的采样区的选择。
上述实施例中的采样区均为规则形状，在本公开的其他实施例中，也不排除采用其他形状的采样区，例如，不规则形状的采样区，在此不再详细说 明。
当然，所述采样区的选取不局限于以上各种，在实际显示时，可以根据显示的需要，选取最方便进行显示且不会带来过大运算量的亚像素形成采样区。在选取采样区时，采样区包括的亚像素越多，分布越均匀，显示效果会越好，但同时需要更大的运算量，反之，采样区包括的亚像素较少，运算量相对较小，但显示效果会有些影响。此外，由于各个亚像素的位置需要显示不同的颜色，为了实现画面的连续显示，采样区的选取还需要满足各个颜色采样区能够连续，所以通常会选择较规则的图形，如菱形、平行四边形、三角形等。
对于整个像素结构边缘部分的亚像素的位置，在进行采样区选取时，可能会与像素结构中部有些差别，如不能形成一个完整的采样区，这就需要在具体显示时，通过其他边缘修饰方法进行修正，这里不做详细介绍。
当然，本公开实施例中，还可以通过其他方法将采样区内的亚像素共同进行信号输出，在此不再一一说明。
本公开实施例中，除了采样区的形状不同对图像的显示效果能够造成影响之外，重复单元中四个亚像素的排列方式的不同，也会对图像的显示效果造成影响。
请参考图12和图13，图12为本公开实施例的重复单元中的四个亚像素的一种排列方式示意图，图13为图12中的重复单元的四个亚像素的采样区的叠加示意图，从图13中可以看出，每一颜色的亚像素的采样区与其他三个颜色的亚像素的采样区的交叠区域相同，该种排列方式下，在很小的显示区域内四种亚像素的采样区交叠显示，输出彩色画面。这种亚像素的输出方式颜色比较均一，是优选的输出方式。
请参考图14和图15，图14为本公开实施例的重复单元中的四个亚像素的另一种排列方式示意图，图15为图14中的重复单元的四个亚像素的采样区的叠加示意图，从图15中可以看出，与图13中的亚像素的输出方式相比，四个亚像素的采样区的交叠面积较小。
请参考图16和图17，图16为本公开实施例的重复单元中的四个亚像素的又一种排列方式示意图，图17为图16中的重复单元的四个亚像素的采样 区的叠加示意图，从图16中可以看出，与图13中的亚像素的输出方式相比，四个亚像素的采样区的交叠面积较小。
本实施例的显示面板可为有机发光二极管显示面板，其中每个亚像素包括一个有机发光二极管(发光单元)，而各有机发光二极管可发出不同颜色光(可通过使用不同的有机发光层实现)，且各有机发光二极管所发光的颜色与其所在亚像素的颜色相同，例如在红色亚像素处的有机发光二极管发红光。
本实施例的显示面板也可为液晶显示面板，液晶显示面板本身不发光，而是对来自背光源的光进行滤光以实现显示；其中，每个亚像素处具有不同颜色的滤光膜，透过彩色滤光膜的光即可转变为相应颜色，其中，各亚像素处彩色滤光膜的颜色与该亚像素的颜色相同，例如在红色亚像素处的彩色滤光膜为红色等。
以上所述是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。

    位于该亚像素位置周围的四个补偿色亚像素，该四个补偿色亚像素组成一菱形，该菱形将该亚像素位置包围其中或与该亚像素位置至少部分重合；或
    位于该亚像素位置周围的三个补偿色亚像素，该三个补偿色亚像素组成一等边三角形，该等边三角形与该亚像素位置至少部分重合；或
    位于该亚像素位置周围的三个补偿色亚像素，该三个补偿色亚像素组成一等腰三角形，该等腰三角形与该亚像素位置至少部分重合。
  23. 根据权利要求20所述的驱动方法，其中，所述用一亚像素位置附近的多个补偿色亚像素的平均作用对该亚像素位置进行显示补偿的步骤包括：
    当一亚像素位置的亚像素为补偿色亚像素时，所述用一亚像素位置附近的多个补偿色亚像素的平均作用对该亚像素位置进行显示补偿的步骤包括：分别采用该亚像素位置的该亚像素本身及该亚像素位置周围的多个补偿色亚像素各自对应的显示比例系数乘以该亚像素位置显示所需的该补偿色的补偿分量，得到该亚像素位置的该亚像素本身及该亚像素位置周围的多个该补偿色的补偿色亚像素各自的子补偿分量；
    当一亚像素位置的亚像素不是补偿色亚像素时，所述用一亚像素位置附 近的多个补偿色亚像素的平均作用对该亚像素位置进行显示补偿的步骤包括：分别采用该亚像素位置周围的多个补偿色亚像素各自的显示比例系数乘以该亚像素位置显示所需的该补偿色的补偿分量，得到该亚像素位置周围的多个该补偿色的补偿色亚像素各自的子补偿分量；
    其中，该亚像素位置附近的每一补偿色亚像素的显示比例系数与该补偿色亚像素与该亚像素位置之间的距离有关。
