Description

像素阵列、显示驱动方法、显示驱动装置和显示装置 技术领域
本发明涉及显示技术领域，特别涉及一种像素阵列、显示驱动方法、显示驱动装置和显示装置。
背景技术
在常规的液晶显示装置、有机发光二极管显示装置中，每个像素是由多个亚像素通过混光来显示颜色的，例如每个像素由红色亚像素、绿色亚像素、蓝色亚像素各一个组成。为了改善视觉效果，人们对于显示装置的分辨率提出了越来越高的要求；这就要求亚像素的尺寸越来越小，但由于工艺限制亚像素尺寸不能无限缩小。为在亚像素尺寸一定的情况下改善显示效果，现有技术中提出了Pentile模式的显示装置。
在Pentile模式的显示装置中，单个像素只由“红绿”或者“蓝绿”两个亚像素组成。在实际显示图像时，Pentile模式的显示装置中的一个像素会“借”用与其相邻的像素的另一种颜色来构成三基色。所以，Pentile模式的显示装置中部分亚像素是“共用”的，这样便减少了亚像素个数，达到以低分辨率去模拟高分辨率的效果，且在视觉效果上实现了比实际分辨率更高的分辨率。
裸眼3D为一种适用于大尺寸显示装置的3D显示模式，它通过设置光栅，以区分进入人左、右眼的信息(包含第一视图和第二视图)，从而使人感觉有3D的效果。但是裸眼3D由于具有挡光光栅设计，在观测过程中，PPI(每英寸像素数)降低很多，有时会降低1半的PPI，从而使观看3D效果降低。为此，若能将裸眼3D技术与Pentile技术相结合，则可提高裸眼3D显示装置的视觉分辨率。
目前，如何将裸眼3D技术与Pentile技术相结合，成为本领域亟待解决的技术问题。

具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合 附图对本发明提供的一种像素阵列、显示驱动方法、显示驱动装置和显示装置进行详细描述。
图1为按照本发明实施例的像素阵列100的俯视图。如图1所示，该像素阵列100包括：若干列亚像素组S1，S2，S3，S4，S5，S6，每列亚像素组均包含M*N个亚像素C1－C9；G1－G9，其中，N为亚像素颜色R，G，B的种类，M为大于等于3的整数。位于奇数列的亚像素组S1，S3，S5中的亚像素的扭曲方向与位于偶数列的亚像素组S2，S4，S6中的亚像素的扭曲方向在列方向上相反。
亚像素的扭曲方向可以指亚像素在列方向上的倾斜方向。亚像素的扭曲方向在列方向上相反可以指亚像素的同侧相对于列方向的倾斜方向相反。如图1所例示的，位于奇数列的亚像素组S1，S3，S5中的亚像素相对于列方向向下扭曲，即：亚像素左侧向下方倾斜(图1中以下向箭头示出)；相应地，位于偶数列的亚像素组S2，S4，S6中的亚像素相对于列方向向上扭曲，即：亚像素左侧向上方倾斜(图1中以上向箭头示出)。
可以理解，如上所述的位于奇数列的亚像素组S1，S3，S5中的亚像素的扭曲方向与位于偶数列的亚像素组S2，S4，S6中的亚像素的扭曲方向可以互换。
扭曲使得按照本发明实施例的像素阵列中的亚像素变形成与常规的亚像素形状(例如矩形)不同的平行四边形。按照本发明的实施例，像素阵列中的每个亚像素的形状均为平行四边形，可选地，为非直角平行四边形。可选地，每列亚像素组中每个亚像素位于列方向上的边相对于列方向对齐，而位于行方向上的边相对于行方向倾斜。每个亚像素(比如位于C1行S6列的绿色亚像素G)位于列方向上的边的长度为a，在行方向上的长度为b。
可选地，该平行四边形中锐角的角度在70～90度之间。进一步可选地，平行四边形中锐角的角度在82～85度之间。
可选地，每个亚像素中位于列方向上的边与不位于列方向上的边的长度比为
Figure PCTCN2015086759-appb-000010
本实施例中，优选地，位于奇数列的亚像素组与位于偶数列的亚像素组(例如亚像素组S1与亚像素组S2之间，或者亚像素组S2与亚 像素组S3之间)在列方向上交错。如图1所示，位于奇数列与位于偶数列的亚像素组中的亚像素(比如位于C1行S1列的蓝色亚像素B与位于C1行S2列的绿色亚像素G)在列方向上的边相互错开，而不对齐。优选地，位于奇数列的亚像素组与位于偶数列的亚像素组在列方向上交错
Figure PCTCN2015086759-appb-000011
此时，可使得像素阵列中相同颜色的亚像素均匀分布，从而可保证显示面板的均匀发光。
需要说明的是，上述亚像素的形状均为平行四边形以及奇数列的亚像素组与偶数列的亚像素组在列方向上交错
Figure PCTCN2015086759-appb-000012
的情况仅作为本实施例的一种实施方式，这并不对本发明的技术方案产生限制。
在一个示例中，以N取值为3，像素阵列为三角像素阵列为例进行说明。三角(Delta，记为“△”)像素阵列是指，在像素阵列中任意最接近的三个不同颜色的亚像素的中心构成的形状均为三角形的阵列。
需要说明的是，尽管图1所示像素阵列包含6列(S1-S6)、9行(G1-G9或C1-C9)的亚像素，但这一像素阵列仅起到示例性的作用，而并不对本申请的技术方案产生限制。
按照本发明实施例的像素阵列不仅可适用在2D显示模式时对Pentile技术的应用，还可适用于在3D显示模式时对Pentile技术的应用，具体方案将在下面内容中进行描述。
图2示出了按照本发明实施例的第一示例性显示驱动方法200的流程图。该显示驱动方法200用于驱动2D显示装置，该2D显示装置包括按照本发明实施例的像素阵列。下面将结合图3－10来描述该显示驱动方法。
按照本发明的实施例，2D显示装置包括例如如图1所示的像素阵列100。像素阵列100中可包含三种不同颜色的亚像素，分别为红色亚像素R、绿色亚像素G和蓝色亚像素B。每个亚像素位于列方向上的边的长度为a，在行方向上的长度为b。
按照本发明实施例的显示驱动方法200包括：
步骤201：将待显示图像划分为多个理论像素单元，并确定每个理论像素单元中各个颜色的颜色分量。
可以按照例如显示装置理论上能够达到的像素分辨率来将待显示图像划分为多个像素单元，即：理论像素单元。每个理论像素单元对应预设数量的亚像素，且根据所对应的亚像素的颜色来确定每个理论像素单元中各个颜色的颜色分量。
理论像素单元所对应的面积称为单位像素单元面积。按照本发明的实施例，单位像素单元面积内可包括预设数量的亚像素。该预设数量可被设置为小于像素阵列中包括的亚像素颜色的数量。可选的，预设数量可以包括：2、
Figure PCTCN2015086759-appb-000013
或1。
图3a～3c为按照本发明实施例的理论像素单元与亚像素的三种不同对应关系的示意图。如图3a～3c所示，假设理论像素单元1所对应区域的尺寸是固定的，可改变的是像素阵列中亚像素的尺寸(即通过在制备像素阵列时对亚像素R/G/B的尺寸进行控制来实现改变)。为简化说明，假设理论像素单元1可以对应一个平行四边形区域，其中该平行四边形区域的一个边长与亚像素不位于列方向的那条边的边长相对应。
举例而言，参见图3a所示，理论像素单元1的单位像素单元面积内可包括1个亚像素，即一个理论像素单元1对应一个亚像素，比如蓝色亚像素B。参见图3b所示，单位像素单元面积内可包括
Figure PCTCN2015086759-appb-000014
个亚像素，即一个理论像素单元1对应一个亚像素(比如蓝色亚像素B)的区域以及与该亚像素在列方向上相邻的一个亚像素(比如绿色亚像素G)的一半区域。参见图3c所示，单位像素单元面积内可包括2个亚像素(比如蓝色亚像素B和绿色亚像素G)，即一个理论像素单元1对应在列方向上相邻的两个亚像素。
需要说明的是，在下面描述的内容中将以一个理论像素单元1对应在列方向上相邻的
Figure PCTCN2015086759-appb-000015
个亚像素的情况为例进行说明。本领域的技术人员应该知晓的是，这是示例性的，其并不对本申请的技术方案产生限制。
图4示出了按照本发明实施例的、在图1所示的像素阵列中一个理论像素单元对应一个半的亚像素的示意图。如图4所示，可根据一个理论像素单元1对应一个半的亚像素的规则，将待显示图像划分成 若干个理论像素单元1(图4中仅示例性的画出了分别在S1列、S2列中的一个理论像素单元)。
在划分完理论像素单元后，根据单位像素单元面积内所包括的亚像素(比如红色亚像素R、绿色亚像素G、蓝色亚像素B)来确定各个理论像素单元1中的红、绿、蓝所占的颜色分量。其中，确定理论像素单元1中各颜色所占的颜色分量的方法可采用现有技术中任一相应的技术手段得以实现。
在步骤201之后，显示驱动方法200还包括：
步骤202：针对每一个亚像素，按照该亚像素对应的第一预设采样区所覆盖的各个理论像素单元中该亚像素的颜色的颜色分量确定该亚像素的发光亮度。
按照本发明的实施例，可以为每个亚像素设置预设采样区。预设采样区限定该亚像素在显示图像过程中需要借用其颜色的相关(例如相邻)亚像素的范围，且因此是包括该亚像素以及(部分地或全部地)包括所述相关亚像素的区域。预定采样区可部分地或者完全覆盖该亚像素和所述相关亚像素对应的理论像素单元。
为简化说明，同样结合图1中的像素阵列100，以位于奇数列的亚像素组与位于偶数列的亚像素组在列方向上交错
Figure PCTCN2015086759-appb-000016
为例来进行描述。
按照本发明的实施例，每一个亚像素所对应的第一预设采样区被设置为菱形采样区。可选地，每一个亚像素的菱形采样区的四个端点可分别被确定为：与该亚像素的中心处于同一列方向上且距离该亚像素的中心为
Figure PCTCN2015086759-appb-000017
的两个点，以及与该亚像素的中心处于同一行方向上且距离该亚像素的中心为b的两个点。
下面将结合附图5－10对在进行2D显示时本发明实施例中各个亚像素对应的采样区进行说明。
图5为进行2D显示时位于G3行S3列的红色亚像素R的采样区2的示意图。图6为图5所示的红色亚像素R的采样区2所覆盖的理论像素单元1的示意图。
如图5和图6所示，在进行2D显示时，位于G3行S3列的红色亚像素R所对应的菱形采样区2的四个端点分别为，与该红色亚像素 的中心处于同一列方向上且距离该红色亚像素的中心为
Figure PCTCN2015086759-appb-000018
的两个点(即位于G1行S3列和G4行S3列的两个蓝色亚像素各自的下侧边的中点)，以及与该红色亚像素的中心处于同一行方向上且距离该红色亚像素的中心为b的两个点(即位于C3行S2列和C3行S4列的两个蓝色亚像素各自的下侧边的中点)。如图6所示，该红色亚像素的菱形采样区2覆盖了7个不同的理论像素单元1的至少部分区域。
图7为进行2D显示时位于G4行S3列的蓝色亚像素B的采样区的示意图。图8为图7所示的蓝色亚像素的采样区所覆盖的理论像素单元的示意图。
如图7和图8所示，在进行2D显示时，位于G4行S3列的蓝色亚像素B所对应的菱形采样区2的四个端点分别为，与该蓝色亚像素的中心处于同一列方向上且距离该蓝色亚像素的中心为
Figure PCTCN2015086759-appb-000019
的两个点(即位于G2行S3列和G5行S3列的两个绿色亚像素各自的下侧边的中点)，以及与该蓝色亚像素的中心处于同一行方向上且距离该蓝色亚像素的中心为b的两个点(即位于C4行S2列和C4行S4列的两个绿色亚像素各自的下侧边的中点)。如图8所示，该蓝色亚像素的菱形采样区2覆盖了7个不同的理论像素单元1的至少部分区域。
图9为进行2D显示时位于G5行S3列的绿色亚像素G的采样区2的示意图。图10为图9所示的绿色亚像素的采样区所覆盖的理论像素单元的示意图。

Figure PCTCN2015086759-appb-000020
的两个点(即位于G3行S3列和G6行S3列的两个红色亚像素各自的下侧边的中点)，以及与该绿色亚像素的中心处于同一行方向上且距离该绿色亚像素的中心为b的两个点(即位于C5行S2列和C5行S4列的两个红色亚像素各自的下侧边的中点)。如图10所示，该绿色亚像素的菱形采样区2覆盖了6个不同的理论像素单元1的至少部分区域。
这种菱形采样区的设置能够使得对整个显示区域完整采样，同时又不会出现采样重叠，从而能够避免因不能完整采样或者采样重叠导 致的画面失真问题。
按照本发明的实施例，确定亚像素的发光亮度可选地通过以下方式来进行，即：针对每一个亚像素，确定其对应的预设采样区与所述预设采样区覆盖的各个理论像素单元中的每一个理论像素单元的重叠面积以及在该理论像素单元中该亚像素的颜色对应的颜色分量；计算每一个理论像素单元对应的重叠面积与所确定的对应的颜色分量的乘积；根据各个乘积的和以及预设采样区的面积设定该亚像素的发光亮度。
按照可选实施例，在使用预设采样区进行采样之后，也可以通过其他适当的方式设定对应亚像素的发光亮度。
图11示出了按照本发明实施例的第一示例性显示驱动装置1100的示意图。显示驱动装置1100用于驱动2D显示装置，该2D显示装置包括按照本发明的实施例的像素阵列，例如图1中所示出的像素阵列100。
显示驱动装置1100包括：第一图像像素划分单元1110和第一亮度设定单元1120。图像像素划分单元1110可将待显示图像划分为多个理论像素单元，并确定每一个理论像素单元中各个颜色的颜色分量。第一亮度设定单元1120可针对每一个亚像素，按照该亚像素对应的第一预设采样区所覆盖的各个理论像素单元中该亚像素的颜色的颜色分量确定该亚像素的发光亮度。
可选地，第一预设采样区为菱形采样区。当位于奇数列的亚像素组与位于偶数列的亚像素组在列方向上交错
Figure PCTCN2015086759-appb-000021
时，该亚像素的菱形采样区的四个端点分别为，与该亚像素的中心处于同一列方向上且距离该亚像素的中心为
Figure PCTCN2015086759-appb-000022
的两个点，以及与该亚像素的中心处于同一行方向上且距离该亚像素的中心为b的两个点。其中，a为一个亚像素位于列方向上的边的长度，b为一个亚像素在行方向上的长度。
需要说明的是，该图像像素划分单元1110可适于执行结合图2－10所描述的步骤101中的动作，该第一亮度设定单元1120可适于执行结合图2－10所描述的步骤102中的动作，此处均不再赘述。

按照本发明的实施例，像素阵列4中可包含三种不同颜色的亚像素，分别为红色亚像素R、绿色亚像素G和蓝色亚像素B。每个亚像素位于列方向上的边的长度为a，在行方向上的长度为b。
按照本发明实施例的显示驱动方法1200包括：
步骤1201：分别将待显示的第一视图和第二视图划分为多个理论像素单元，并确定每一个理论像素单元中各个颜色的颜色分量。
可选地，在步骤1201中，可以将第一视图按照3D显示装置的理论上能够达到的像素的个数划分为多个理论像素单元。之后确定各个理论像素单元中的红、绿、蓝所占的颜色分量。并按照相同的方式，得到第二视图对应的多个理论像素单元以及各个理论像素单元中红、绿、蓝所占的颜色分量。
本实施例中，仍是以一个理论像素单元对应一个亚像素的区域和与其在列方向上相邻的一个亚像素的一半区域的情况为例来进行说明的。
步骤1202：针对每一个视图的每一个亚像素，按照该亚像素对应的第二预设采样区所覆盖的、属于该视图的各个理论像素单元中该亚像素的颜色的颜色分量确定该亚像素的发光亮度。
按照本发明的实施例，每一个亚像素所对应的第二预设采样区被设置为矩形采样区。可选地，每一个亚像素的矩形采样区的四条边的中点可分别被确定为：与该亚像素的中心处于同一列方向上且距离该 亚像素的中心为

这种矩形采样区的设置能够使得在进行3D显示时对整个显示区域完整采样同时不出现采样重叠，从而能够避免因不能完整采样或者采样重叠导致的画面失真问题。
