Description

一种像素排列结构、显示装置及显示方法 技术领域
本发明涉及显示技术领域，尤其涉及一种像素排列结构、显示装置及显示方法。
背景技术
显示器已经逐渐被各种电子设备如：移动电话、个人数字助理(PDA)、数码相机、计算机或笔记本所广泛应用，而高分辨率的显示器逐渐成为各种电子设备的重要性能之一。
传统显示器常见的像素设计是，采用三个亚像素：红色、绿色、蓝色(RGB)亚像素组成一个像素。多个上述像素成矩阵形式排列。用户在观看显示器的过程中，其视觉的分辨率即为该显示器的物理分辨率(实际的分辨率)。因此，为了提高显示器的显示效果，需要在制作显示器的过程中采用提高图像的采样率(pixels per inch，PPI)的设计，即提高每英寸所拥有的像素数目。但是随着用户对显示器屏幕的感受要求增加，目前显示面板制作工艺已达到极限。为了在亚像素尺寸一定的情况下改善显示效果，现有技术提出了Pen tile模式的显示装置。该显示装置中的像素阵列参照图1所示，奇数行的亚像素11中亚像素依次按照R、G、B的顺序排列，而偶数行的亚像素12依次按照B、R、G的方式进行排列。在显示过程中，在像素排列结构上设置采样区，将采样区对应的多个红色亚像素、绿色亚像素和/或蓝色亚像素公用，从而在视觉效果上实现比实际分辨率更高的分辨率。但是，在Pen tile模式的显示装置中，由于像素阵列中亚像素的排列方向单一，所以在某些方向上颜色不均匀，从而影响显示面板的显示效果。
发明内容
本发明的实施例提供一种像素排列结构、显示装置及显示方法，用于提高显示面板的显示效果。
本发明的第一方面提供一种像素排列结构，包括沿着纵向方向平行排列的至少一个像素单元，每个像素单元包括沿着横向方向交替排列的第一像素和第二像素；

本发明的第二方面提供一种显示装置，包括上述任一种像素排列结构。
本发明的第三方面提供一种显示方法，用于上述显示装置，所述方法包括：
接收图像信号，并对接收到的图像信号进行数据处理；
根据数据处理结果在所述显示装置的像素排列结构中设置至少一个采样区；
公用所述采样区对应的第一亚像素、第二亚像素和/或第三亚像素 来输出像素公用后的显示信号；
根据所述像素公用后的显示信号，对所述图像信号进行显示。
所述采样区的形状可以为菱形。
所述采样区可以包括第一亚像素和第二亚像素和第三亚像素中的至少一个亚像素的至少一部分；
所述公用所述采样区对应的多个第一亚像素、第二亚像素和/或第三亚像素来输出像素公用后的显示信号包括：通过所述采样区的主亚像素输出所述主显示信号，并且通过所述采样区的辅亚像素输出公用显示信号，其中所述主亚像素为第一亚像素、第二亚像素和第三亚像素中完全包含在采样区内的亚像素，所述辅亚像素为第一亚像素、第二亚像素和第三亚像素中部分地包含在采样区内的亚像素，并且所述公用显示信号为所述主显示信号的配比信号。

所述主亚像素可以为绿色，所述辅亚像素可以为红色和蓝色；或
所述主亚像素可以为蓝色，所述辅亚像素可以为红色和绿色。
本发明实施例提供的像素排列结构、显示装置及显示方法中，因为位于第一行的亚像素向第一方向倾斜，位于第二行的亚像素向第二方向倾斜，其中所述第一方向和第二方向在横向上相反，所以位于第一行的亚像素和位于第二行的亚像素可以在出光方向上相互进行光补偿。这样可以避免像素排列结构在某些方向上颜色不均匀，从而可以提高显示面板的显示效果。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动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。
需要说明的是，本发明实施例中行和列是一种相对的概念。本发明实施例中描述的行是以水平方向为例进行说明的，即本申请中所述的横向；列是以竖直方向为例进行说明的，即本申请中所述的纵向。然而，由于像素为矩阵形式排列，因此当观测的方向不同时，行和列可以互换，横向和纵向也可以互换。
图2为本发明的一个实施例提供的像素排列结构的示意图。如图2所示，该像素排列结构包括沿着纵向方向相互平行排列的至少一个像素单元30，每个像素单元30包括沿着横向方向相互交替排列的第一像 素11和第二像素12。
图3为图2所示像素结构的第一像素11和第二像素12的示意图。如图3所示，第一像素11包括沿着横向方向在第一行L1依次排列的第一亚像素101和第二亚像素102以及沿着横向方向在第二行L2的第三亚像素103；第二像素12包括沿着横向方向在第一行L1的第三亚像素103和沿着横向方向在第二行L2依次排列的第一亚像素101和第二亚像素102。
位于所述第一行L1的亚像素向第一方向倾斜(图2中以左向箭头示出)，位于所述第二行L2的亚像素向第二方向倾斜(图2中以右向箭头示出)，其中所述第一方向和第二方向在横向上相反。
虽然图2、3中均以位于第一行的亚像素的形状为向左倾斜的平行四边形、位于第二行的亚像素的形状为向右倾斜的平行四边形为例进行说明，但位于第一行的亚像素的形状为向左倾斜的平行四边形、位于第二行的亚像素的形状为向右倾斜的平行四边形仅为本发明实施例的一种实现方式，并不能作为对本发明的限制。
上述位于第一行L1的第一亚像素101和第二亚像素102具体是指：沿着横向方向依次排列的第一亚像素101和第二亚像素102形成第一行L1，即第一行L1的中心线位于第一亚像素101和第二亚像素102的中心点连线上。因此，在图2中，对于顶部的第一像素单元而言，第一行为L1，第二行为L2；对于下面的第二像素单元而言，第一行为L3，第二行为L4。以此类推，对于第n像素单元而言，第一行为L2n-1，第二行为L2n，其中n为正整数。第n像素单元的第一行L2n-1中各个亚像素的排列方式与第一像素单元的第一行L1中各个亚像素的排列方式相同，第n像素单元的第二行L2n中各个亚像素的排列方式与第一像素单元的第二行L2中各个亚像素的排列方式相同。
在本发明实施例提供的像素排列结构中，因为位于第一行的亚像素向第一方向倾斜，位于第二行的亚像素向第二方向倾斜，其中所述第一方向和第二方向在横向上相反，所以位于第一行的亚像素和位于第二行的亚像素可以在出光方向上相互补偿。这样可以避免像素排列结构在某些方向上颜色不均匀，从而可以提高显示面板的显示效果。
图4为本发明的一个实施例提供的像素单元中位于第一行和第二行的亚像素的形状的示意图。如图4所示，对于每个像素单元30，位 于第一行的亚像素的形状可以为第一平行四边形P1，位于第二行的亚像素的形状可以为与所述第一平行四边形P1互为镜像的第二平行四边形P2。
在本发明的一个实施例中，第一像素中的第一亚像素、第二亚像素以及第二像素中的第三亚像素的形状为第一平行四边形，而第一像素中的第三亚像素以及第二像素的第一亚像素和第二亚像素的形状为第二平行四边形。
在本发明的一个实施例中，互为镜像是指：所述第一平行四边形P1的高度h1与所述第二平行四边形P2的高度h2相等，所述第一平行四边形P1的下底边d1长度与所述第二平行四边形P2的上底边d2长度相等，所述第一平行四边形P1内的锐角角度a1与所述第二平行四边形P2内的锐角角度a2相同，所述第一平行四边形P1的斜边的倾斜方向与所述第二平行四边形P2的斜边的倾斜方向相反。
上述实施例中位于第一行的亚像素的形状为第一平行四边形，位于第二行的亚像素的形状为第二平行四边形，且第一平行四边形与第二平行四边形倾斜方向相反。因为第一平行四边形与第二平行四边形的倾斜方向相反，所以位于第一行的亚像素和位于第二行的亚像素可以在出光方向上相互补偿。这样可以避免像素排列结构在某些方向上颜色不均匀，从而提高显示面板的显示效果。
以上参考图2至图4描述了位于第一行的亚像素与位于第二行的亚像素在纵向方向上对齐的像素排列结构的实施例。下面将参考图5和图6来介绍位于第一行的亚像素与位于第二行的亚像素在纵向方向上不对齐的像素排列结构的实施例。
图5为本发明的另一个实施例提供的像素排列结构的示意图。在该像素排列结构中，对于每个像素单元30，位于第一行的亚像素(第一平行四边形P1)与位于第二行的亚像素(第二平行四边形P2)的相邻的两个底边在纵向的投影(T1、T2)不重合。
图6为图5所示像素排列结构的像素单元中位于第一行和第二行的亚像素的位置关系的示意图。图6中以第一平行四边形P1与第二平行四边形P2的相邻的两个底边分别为第一平行四边形P1的下底边d1和第二平行四边形P2的上底边d2为例进行说明。如图6所示，第一平行四边形P1的下底边d1和第二平行四边形P2的上底边d2在纵向 上不完全对齐。
在图6所示的实施例中，所述第一平行四边形P1与所述第二平行四边形P2相邻的两个底边d1、d2中，所述第一平行四边形P1的下底边d1的一个端点a1在纵向的投影可以位于所述第二平行四边形P2的上底边d2在纵向的投影的中点M2；或者所述第二平行四边形P2的上底边的一个端点a2在纵向的投影可以位于所述第一平行四边形P1的下底边d1在纵向的投影的中点M1。
上述实施例中，所述第一平行四边形与所述第二平行四边形的形状互为镜像，所以第一平行四边形与第二平行四边形的高度、宽度以及倾斜角度相同。由于所述第一平行四边形与所述第二平行四边形的相邻的两个底边在纵向的投影不重合，所以相比于现有技术，在显示过程中，在像素排列结构上设置采样区时，采样区内各亚像素分布更均匀。因此，本发明实施例可以进一步提高显示面板的显示效果。
图7a示出了本发明的一个实施例提供的单位像素面积。参照图7a所示，由传统R、G、B三个亚像素组成的一个像素的像素面积形成了单位像素面积。当然，所述单位像素面积是一个相对面积，作为基准的R、G、B三个亚像素的面积变大时，单位像素面积也会相应变大。单位像素面积中每一个亚像素由一条数据线进行控制，单位像素面积需三条数据线进行控制。
图7b至7d为对于不同的亚像素面积在单位像素面积内包括的亚像素的数目的示意图。如图7b至7d所示，单位像素面积内可以包括预设数量的亚像素，所述预设数量可以包括以下任一个：2、1.5和1。
例如，在图7b所示的实施例中，亚像素的面积为图7a中亚像素面积的1.5倍，在单位像素面积内包括2个亚像素，即预设数量为2。在图7c所示的实施例中，亚像素的面积为图7a中亚像素面积的2倍，单位像素面积内包括1.5个亚像素，即预设数量为1.5。在7d所示的实施例中，亚像素的面积为图7a中亚像素面积的3倍，单位像素面积内包括1个亚像素，即预设数量为1。
图8为现有技术中单位像素面积内包括3个亚像素的像素排列结构的示意图。参照图8所示，图8对应于图7中7a的像素排列方式。该亚像素排列结构中亚像素为矩形，单位像素面积内包括横向排列的三个亚像素。三个亚像素分别位于A1列、A2列和A3列，由控制A1 列、A2列和A3列的三条数据线进行控制。
图9为本发明的一个实施例提供的单位像素面积内包括2个亚像素的像素排列结构的示意图。参照图9所示，图9对应于图7中7b的像素排列方式，为本发明实施例的一种像素排列结构，该像素排列结构中亚像素为平行四边形。单位像素面积内包括横向排列的2个亚像素。2个亚像素分别位于S1列和S2列，由控制S1列和S2列的2条数据线进行控制。通过像素阵列中部分亚像素的公用，图9所示的像素排列结构可以实现的显示效果与图8所示的像素排列结构的显示效果相当。但是，图9中亚像素面积为图8中亚像素面积的1.5倍，数据线数量减少1/3，所以可以简化显示面板的生产工艺。
图10为本发明的一个实施例提供的单位像素面积内包括1.5个亚像素的像素排列结构的示意图。参照图10所示，图10对应于图7中7c的像素排列方式，为本发明实施例的一种像素排列结构，该像素排列结构中亚像素为平行四边形。单位像素面积内包括横向排列的1.5个亚像素。1.5个亚像素分别位于S1列和S2列的左侧，由控制S1列和S2列的数据线进行控制。图10中亚像素面积为图8中亚像素面积的2倍，数据线数量减少1/2，所以可以简化显示面板的生产工艺。
图11为本发明的一个实施例提供的单位像素面积内包括1个亚像素的像素排列结构的示意图。参照图11所示，图11对应于图7中7d的像素排列方式，为本发明实施例的一种像素排列结构，该像素排列结构中亚像素为平行四边形。单位像素面积内包括1个亚像素。该亚像素位于S1列，由控制S1的数据线进行控制。图11中亚像素面积为图8中亚像素面积的3倍，数据线数量减少2/3，所以可以简化显示面板的生产工艺。
上述实施例中所述第一平行四边形和所述第二平行四边形内的锐角的角度可以在70～90度之间。
上述实施例中所述第一平行四边形和所述第二平行四边形内的锐角的角度可以为82～85度。
上述实施例中所述第一亚像素可以为红色，所述第二亚像素可以为绿色，所述第三亚像素可以为蓝色。
当然，上述实施例中的亚像素还可以为其他的组合方式。例如：所述第一亚像素为红色，所述第二亚像素为蓝色，所述第三亚像素为 绿色；或者，所述第一亚像素为绿色，所述第二亚像素为红色，所述第三亚像素为蓝色；或者，所述第一亚像素为绿色，所述第二亚像素为蓝色，所述第三亚像素为红色；或者，所述第一亚像素为蓝色，所述第二亚像素为绿色，所述第三亚像素为红色；或者，所述第一亚像素为蓝色，所述第二亚像素为红色，所述第三亚像素为绿色。
本发明的一个实施例提供一种显示装置，所述显示装置包括上述实施例中任一项所述的像素排列结构。
在本发明的实施例中，显示装置可以为：电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本发明实施例提供的显示装置中，每个像素单元包括沿着横向方向交替排列的第一像素和第二像素。所述第一像素包括沿着横向方向在第一行依次排列的第一亚像素和第二亚像素以及沿着横向方向在第二行的第三亚像素。所述第二像素包括沿着横向方向在第一行的第三亚像素和沿着横向方向在第二行依次排列的第一亚像素和第二亚像素。位于所述第一行的亚像素向第一方向倾斜，并且位于所述第二行的亚像素向第二方向倾斜，其中所述第一方向和第二方向在横向上相反。因此，位于第一行的亚像素和位于第二行的亚像素可以在出光方向上相互补偿。这样可以避免像素排列结构在某些方向上颜色不均匀，从而可以提高显示面板的显示效果。
图12为本发明的一个实施例提供的显示方法的流程图，该显示方法用于上述实施例中的显示装置。参照图12所示，该显示方法包括如下步骤：
S801：接收图像信号，并对接收到的图像信号进行数据处理。
S802：根据数据处理结果在所述显示装置的像素排列结构中设置至少一个采样区。
S803：公用所述采样区对应的多个第一亚像素、第二亚像素和/或第三亚像素来输出像素公用后的显示信号。
S804：根据所述像素公用后的显示信号，对所述图像信号进行显示。
上述像素公用后的显示信号可以分为主显示信号和公用信号。主显示信号为采样区中的主要用于显示的亚像素输出的信号。公用信号 为采样区中除了上述主要用于显示的亚像素以外的用于公用的亚像素输出的信号。像素公用后的显示信号可以传输至显示面板的像素电极。在像素电极和公共电极的共同作用下，对应于采样区的液晶根据上述主显示信号和公用信号发生不同方向的偏转，最终在显示面板上显示所述图像信号。
上述实施例提供的显示方法中，首先接收图像信号，并对接收到的图像信号进行数据处理；然后根据数据处理结果在所述显示装置的像素排列结构中设置至少一个采样区；其次通过公用所述采样区对应的第一亚像素、第二亚像素和/或第三亚像素来输出像素公用后的显示信号；最后根据所述像素公用后的显示信号，对所述图像信号进行显示。在实现上述显示方法的显示面板的像素阵列中，位于第一行的亚像素向第一方向倾斜，位于第二行的亚像素向第二方向倾斜，其中，所述第一方向和第二方向在横向上相反。因此，位于第一行的亚像素和位于第二行的亚像素可以在出光方向上相互补偿。这样可以避免像素排列结构在某些方向上颜色不均匀，从而可以提高显示面板的显示效果。
图13为本发明的一个实施例提供的单个采样区的示意图。如图13所示，采样区的形状可以为菱形。而且，采样区内可以包括第一亚像素、第二亚像素和第三亚像素中的至少一个亚像素的至少一部分。
在本发明的实施例中，公用采样区对应的第一亚像素、第二亚像素和/或第三亚像素来输出像素公用后的显示信号可以包括：通过所述采样区的主亚像素输出主显示信号，并且通过所述采样区的辅亚像素输出公用显示信号。所述主亚像素可以为第一亚像素、第二亚像素和第三亚像素中完全包含在采样区内的亚像素。所述辅亚像素可以为第一亚像素、第二亚像素和第三亚像素中部分地包含在采样区内的亚像素。所述公用显示信号为所述主显示信号的配比信号。
参照图13所示，采样区90的形状可以为菱形。采样区90内包括一个完整的第二亚像素，并且采样区90的轮廓边界分布于该第二亚像素周围的三个第一亚像素和三个第三亚像素上。也就是说，采样区90还包括该第二亚像素周围的三个第一亚像素和三个第三亚像素的一部分。在这种情况下，完全包含在采样区内的第二亚像素为主亚像素，输出主显示信号。部分地包含在采样区内的亚像素，即，采样区轮廓 边界上的三个第一亚像素和三个第三亚像素为辅亚像素，输出公用显示信号。
图14为本发明的一个实施例提供的多个连续采样区的示意图。参照图14所示，当在步骤S802中，根据数据处理结果在所述显示装置的像素排列结构中设置多个连续采样区时，多个连续菱形采样区90被设置为相邻两个采样区相互连接但不交叠。图14中以四个连续采样区、且主亚像素为第二亚像素为例进行说明。本发明实施例还可以包括更多连续采样区以及第一亚像素或第三亚像素为主亚像素的情况，其与图14中采样区的设置方式类似，本发明再做详细说明。
本发明实施例中，公用信号为主显示信号的配比信号具体是指：根据上述图像信号，对预显示图像进行分析、处理(例如对预显示图像的画质、亮度、颜色等信息进行分析和处理)，确定主亚像素输出的主显示信号并以上述主显示信号为基准获得分别向辅亚像素输入信号的权重。具有上述权重的信号为配比信号。各个配比信号的权重之和为1。
上述实施例中主亚像素和辅亚像素的分布形式包括以下三种：所述主亚像素为红色，所述辅亚像素为绿色和蓝色；或者，所述主亚像素为绿色，所述辅亚像素为红色和蓝色；或者，所述主亚像素为蓝色，所述辅亚像素为红色和绿色。
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附的权利要求的保护范围为准。
