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。

对于各种不同具有显示装置的客户终端而言，使用者的视角往往更多集 中在显示面板的中心区域，而对远离显示面板中心区域的部分则往往不太关注，即显示面板周边的亮度需求可能比中心位置的要低。而在通常的像素单元的图案设计方案中，各像素单元在有效显示区域内均匀排布，各子像素的宽度/高度相同，整个面板显示区域的透过率是均匀一致的，这就产生了不必要的亮度浪费，对降低功耗、提升待机时间不利。
图1a、1b为一种显示基板的像素设计示意图。该显示基板包括：衬底基板100，多个呈阵列排列在衬底基板100上的像素单元123。每个像素单元123包括多个子像素单元101，例如包括红色子像素1011、绿色子像素1012和蓝色子像素1013三个子像素，各红色子像素1011、各绿色子像素1012和各蓝色子像素1013分别等高、等宽，且红色子像素1011、绿色子像素1012和蓝色子像素1013开口面积相同。等高是指在列方向上的长度相等，等宽是指在行方向上的长度相同，以下各实施例可与此相同。例如，由多个像素单元构成的阵列可以是各行各列彼此对齐的矩阵，也可以是各行各列彼此错开例如半个子像素的宽度或高度的排列方式，以下各实施例可与此相同。
如图1a所示，该显示基板为阵列基板，列方向相邻的两个子像素单元101之间设置有栅线102，行方向相邻的两个子像素单元101之间设置有数据线103。例如，栅线102沿行方向延伸，数据线103沿列方向延伸。例如，多条栅线102和多条数据线103交叉限定多个子像素单元。
如图1b所示，该显示基板为彩膜基板，例如，彩膜基板包括黑矩阵和彩色树脂层，光线经每个子像素的彩色树脂层出射对应颜色的光，列方向相邻的两个子像素单元101之间可设置有黑矩阵104，行方向相邻的两个子像素单元101之间也设置有黑矩阵104。即，每相邻的两个子像素之间设有黑矩阵，黑矩阵用以遮光以防止串扰和提高对比度。例如，行方向的黑矩阵104具有相同的宽度，列方向的黑矩阵104具有相同的宽度。例如，进一步行方向的黑矩阵104和列方向的黑矩阵104具有相同的宽度。宽度是指垂直于黑矩阵延伸方向的长度。
例如，在液晶显示装置中，显示基板通过信号线来控制像素电极和公共电极来形成不同的电场以控制液晶层中液晶分子的排布，进而控制透过每一个子像素的光线，最终使像素单元中每个不同颜色的子像素具有不同的亮度。每个像素单元中三种不同颜色的光根据需要按不同比例混合，使每个像素单 元呈现出不同色彩，完成彩色显示。像素区域的亮度是保证显示效果的重要因素之一，提高子像素的开口面积以及开口率是保证在功耗不增加的情况下提升显示效果的重要环节。显然，所有子像素单元具有同样开口面积的显示基板具有良好的画面均一性，但对在保证合理画面均一性的基础上降低功耗是不利的。
本发明至少一实施例提供一种显示基板，包括衬底基板和设置在衬底基板上的多个子像素单元。该多个子像素单元呈阵列排布且阵列包括多行和多列，每行或每列子像素包括第一子像素和第二子像素，且该行子像素形成的线段在行方向上具有中点或者该列子像素形成的线段在列方向上具有中点，第一子像素和第二子像素用于显示同一颜色，第一子像素到中点的距离小于第二子像素到中点的距离，第一子像素的开口面积大于第二子像素的开口面积。
本发明至少一实施例提供的显示基板，可以提升显示面板中心区域的透过率，达到提升中心区域亮度、降低功耗的目标，可使显示基板中各部分像素(子像素)开口率合理分布。
下面通过几个实施例进行说明。
实施例1
本实施例提供一种显示基板，如图2a、2b所示，包括衬底基板100和设置在衬底基板100上的多个子像素单元101。多个子像素单元101呈阵列(图中所示为矩阵)排布且该阵列包括多行和多列，每行子像素包括第一子像素P1和第二子像素P2且该行子像素形成的线段在行方向上具有中点105(或者该行子像素中用于显示同一颜色的子像素单元形成的线段在行方向上具有中点105)，第一子像素P1和第二子像素P2用于显示同一颜色，第一子像素P1到行方向上的中点105的距离小于第二子像素P2到行方向上的中点105的距离，第一子像素P1的开口面积大于第二子像素P2的开口面积。
例如，参考图2a、2b所示，行方向是指平行于纸面的水平方向，列方向是指平行于纸面与水平方向垂直的方向，以下各实施例可与此相同。
例如，子像素的开口面积是指该子像素的出光面积或透光面积。相应地，像素单元的开口面积是指构成该像素单元的各个子像素的开口面积之和。以下各实施例可与此相同。
例如，每行子像素包括三种颜色的子像素，分别为红色子像素1011、绿色子像素1012和蓝色子像素1013。红色子像素1011用于显示红色，绿色子像素1012用于显示绿色，蓝色子像素1013用于显示蓝色。例如，一个红色子像素1011、一个绿色子像素1012和一个蓝色子像素1013可构成一个像素单元123。但是，本发明的实施例不限于上述三原色配置，而且也可以包括其他颜色的子像素，例如白色子像素。
需要说明的是，图2a、2b中以第一子像素P1和第二子像素P2为绿色子像素为例进行说明。第一子像素P1和第二子像素P2亦可为用于显示其他颜色的子像素。
图2a、2b示出了显示基板上呈阵列排布的多个子像素单元101，图中示出了24个像素单元，其中的省略号代表其他未示出的像素单元。
需要说明的是，本实施例中，行方向上的中点为每行子像素形成的线段在行方向上位于中间位置的一个抽象的点，以方便描述，而不是该显示基板中客观存在的具体结构。类似地，第一子像素和第二子像素也以其相对于行方向上的中点距离的大小而定义，而非特指某一位置的某个子像素。并且，第一子像素P1和第二子像素P2并不限于位于每行子像素形成的线段的中点105的同一侧，第一子像素P1和第二子像素P2可位于每行子像素形成的线段的中点105的两侧。以下各实施例可与此相同。例如，在绿色子像素1121-1128中，比较而言，对于绿色子像素1121和绿色子像素1122，绿色子像素1121为第一子像素P1，绿色子像素1122为第二子像素P2；对于绿色子像素1122和绿色子像素1123，绿色子像素1122为第一子像素P1，绿色子像素1123为第二子像素P2；对于绿色子像素1123和绿色子像素1124，则绿色子像素1123为第一子像素P1，绿色子像素1124为第二子像素P2；对于绿色子像素1122和绿色子像素1127，则绿色子像素1122为第一子像素P1，绿色子像素1127为第二子像素P2。
例如，如图2a、2b所示，与行方向上的中点105具有相等距离的用于显示同一颜色的子像素具有相等的开口面积。
一个像素单元包括多个用于显示不同颜色的子像素。例如，一个像素单元包括的多个用于显示不同颜色的子像素中，用于显示不同颜色的子像素单元的变化规律可相同。例如，如图2a、2b所示，具有上述结构的子像素P1 和P2分属不同的像素单元，则包括子像素P1的第一像素单元1231(例如图中的右侧边)到行方向上的中点105的距离小于包括子像素P2的第二像素单元1232(例如图中的右侧边)到行方向上的中点105的距离，子像素P1和P2不限于图中标示的绿色子像素，亦可指代用于显示同一颜色的其他子像素。第一像素单元1231的开口面积大于第二像素单元1232的开口面积。
例如，如图2a、2b所示，每行子像素可具有相同的高度。用于显示同一颜色的子像素的开口面积的变化可通过子像素宽度的变化来加以调整。
本实施例提供的上述显示基板可以提升显示面板中心区域的透过率，达到提升中心区域亮度、降低功耗的目标，可使显示基板中各部分像素(子像素)开口率合理分布。
在本实施例的另一示例中，如图2a、2b所示，每行子像素中，从靠近行方向上的中点105位置处向远离行方向上的中点105位置处，用于显示同一颜色的各子像素的开口面积逐渐减小。以绿色子像素1121-1124为例，绿色子像素1121、1122、1123、1124的开口面积逐渐减小。因彼此紧邻的用于显示同一颜色的子像素的开口面积逐渐减小，则各相邻的用于显示同一颜色的子像素的亮度也是逐渐减小的。从而使得兼顾画面均一性的同时使中心区域亮度提升，且每一行不同位置处亮度差异逐渐变化，以取得较好的视觉效果。
例如，从靠近行方向上的中点105位置处向远离行方向上的中点105位置处，用于显示红色的红色子像素1011的开口面积逐渐减小，用于显示绿色的绿色子像素1012的开口面积逐渐减小，用于显示蓝色的蓝色子像素1013的开口面积逐渐减小。则从靠近行方向上的中点105位置处向远离行方向上的中点105位置处，各像素单元123的开口面积逐渐减小。因各像素单元的开口面积逐渐减小，则各像素单元的亮度也是逐渐减小的。从而使得兼顾画面均一性的同时使中心区域亮度提升，且每一行不同位置处亮度差异逐渐变化，以取得较好的视觉效果。
在本实施例的另一示例中，每行子像素中，从靠近行方向上的中点105位置处向远离行方向上的中点105位置处，用于显示同一颜色的各子像素单元101的开口面积呈等差数列减小。同样，因各相邻的用于显示同一颜色的子像素的亮度呈等差数列减小。从而使得中心区域亮度提升，且每一行不同位置处亮度差异呈等差数列逐渐变化，以取得较好的视觉效果。
例如，每行子像素中，从靠近行方向上的中点105位置处向远离行方向上的中点105位置处，各像素单元的开口面积呈等差数列减小。同样，因各像素单元的亮度呈等差数列减小，从而使得中心区域亮度提升，且每一行不同位置处亮度差异呈等差数列逐渐变化，以取得较好的视觉效果。
例如，在每行像素单元数为偶数，各子像素等高，从靠近行方向上的中点105位置处向远离行方向上的中点105位置处各像素单元以及用于显示同一颜色的子像素的开口面积均呈等差数列减小的情况下，设置显示基板每一行具有N个像素单元，其中，中心第N/2(二分之一N)个及第N/2+1(二分之一N加一)个像素单元的开口面积为X(最大像素开口面积)，设置其边缘上最小的像素单元开口面积为kX，相邻像素单元间开口面积呈等差数列，则公差为(1-k)X/(N/2-1)，则其像素单元的总开口面积为Sn＝2×1/2×(kX+X)×N/2＝1/2×(1+K)×X×N。假设在通常设计(即每个像素的开口面积相同)中，每个像素开口面积为A，则相比于同样总面积的通常像素，对于中心像素，透过率为X＝2A/(1+k)，透过率提升比为(X-A)/A＝(2-1-k)/(1+k)＝(1-k)/(1+k)，由此可以得出K值(即每行中最小像素开口除以最大像素开口的比值)与透过率提升比例的关系表：
表一：K值与透过率提升比例的关系表
Figure PCTCN2016094987-appb-000001
由表一可以看出K越小，其中心透过率提升比例越高。考虑正常显示面板的画面均一性要求，K值设置为0.8的情况下，中心像素单元(子像素)透过率可提升11.1％。例如，综合透过率提升比例和显示面板的画面均一性要求，K值可大于等于0.8小于等于0.95，进一步的，K值可大于等于0.8小于等于0.9。
例如，在本发明一实施例提供的显示基板中，每行子像素中，开口面积最小的子像素单元与用于显示同一颜色的开口面积最大的子像素单元的开口面积的比值(K值)大于等于0.8小于1。同样，在显示不同颜色的子像素变化规律一致的情况下，每行子像素中，开口面积最小的像素单元与开口面积最大的像素单元的开口面积的比值(K值)大于等于0.8小于1。
例如，在本实施例的一个示例中，如图2a、2b所示，每行子像素中，第一子像素P1和第二子像素P2为彼此紧邻的用于显示同一颜色的子像素。
例如，在本实施例中，每列子像素中，各个子像素的开口面积是相同的。例如，在每一行子像素中，各个子像素是等高的。在不同行中，各个子像素也是等高的。开口面积的变化可以通过子像素宽度的变化来调整。子像素的宽度例如是指子像素在行方向上的长度。子像素的高度例如是指子像素在列方向上的长度。
需要说明的是，在本实施例中，显示基板可为阵列基板或彩膜基板。以下各实施例可与此相同。
如图2a所示，该显示基板为阵列基板，列方向相邻的两个子像素单元101之间可设置有栅线102，行方向相邻的两个子像素单元101之间可设置有数据线103。栅线102沿行方向延伸，数据线103沿列方向延伸。多条栅线102和多条数据线103交叉限定多个子像素单元。例如，在阵列基板上还可设置有像素电极，像素电极与公共电极之间可形成电场用以驱动液晶分子偏转(液晶显示面板，在阵列基板和彩膜基板之间设置有液晶层)，实现对光线强弱的控制，然后通过彩膜基板的滤光作用，实现彩色图像显示。公共电极可形成在阵列基板上，亦可形成在彩膜基板上。需要说明的是，本实施例的阵列基板不限于应用于液晶显示面板中，例如亦可应用在有机电致发光二极管显示面板中，以下各实施例可与此相同。
如图2b所示，该显示基板为彩膜基板，列方向相邻的两个子像素单元101之间可设置有黑矩阵104，行方向相邻的两个子像素单元101之间可设置有黑矩阵104。即，每相邻的两个子像素之间设有黑矩阵，黑矩阵用以遮光以防止串扰和提高对比度。例如，行方向的黑矩阵104具有相同的宽度，列方向的黑矩阵104具有相同的宽度。例如，行方向的黑矩阵104和列方向的黑矩阵104具有相同的宽度。宽度例如是指垂直于黑矩阵延伸方向的长度。以下各实施例可与此相同。
在本实施例中，一个像素单元中，用于显示不同颜色的子像素单元的开口面积可相同或不同。以下各实施例可与此相同。图2a、2b中以一个像素单元中用于显示不同颜色的子像素单元的开口面积相同为例进行说明。
例如，在本实施例中，呈矩阵排布的多个子像素单元构成轴对称结构。 例如，以每行子像素形成的线段在行方向上的中点构成的线段为对称轴，或以每行像素单元形成的线段在行方向上的中点构成的线段为对称轴。
本实施例中，亦可将“行”替换为“列”，相应的，“行方向”替换为“列方向”。实施例2中可与此相同。
实施例2
本实施例提供一种显示基板，如图3a、3b所示，包括衬底基板100和设置在衬底基板100上的多个子像素单元101。多个子像素单元101呈阵列(如图所示为矩阵)排布且该阵列包括多行和多列，每行子像素包括第一子像素P1和第二子像素P2且该行子像素形成的线段在行方向上具有中点105，第一子像素P1和第二子像素P2用于显示同一颜色，第一子像素P1到行方向上的中点105的距离小于第二子像素P2到行方向上的中点105的距离，第一子像素P1的开口面积大于第二子像素P2的开口面积。
例如，如图3a、3b所示，每行子像素中，第一子像素P1和第二子像素P2位于行方向上的中点105的同一侧，第一子像素P1和第二子像素P2之间设置有与第一子像素P1和第二子像素P2显示同一颜色的至少一个中间子像P3，至少一个中间子像素P3的开口面积可与第一子像素P1或第二子像素P2的开口面积相同。图3a、3b中以第一子像素P1和第二子像素P2之间设置有与第一子像素P1和第二子像素P2显示同一颜色的一个中间子像P3，中间子像素P3的开口面积与第一子像素P1的开口面积相同为例进行说明。
例如，在本实施例的一个示例中，如图3a、3b所示，相邻的开口面积相同的多个用于显示同一颜色的子像素为一个子像素单元组11，图中标注了三个子像素单元组111、112和113，在该行方向上，还包括多个开口面积相同的用于显示同一颜色的子像素构成的子像素单元组。每行子像素中，从靠近行方向上的中点105位置处向远离行方向上的中点105位置处，用于显示同一颜色的子像素单元组11的开口面积逐渐减小。例如，用于显示同一颜色的子像素单元组11的开口面积呈等差数列减小。此处等差数列的公差可参照实施例1中的叙述。K的数值亦可参见实施例1中的叙述。公差以及K值可与实施例1中的相同。
例如，如图3a、3b所示，相邻的开口面积相同的像素单元为一个像素单元组14，图中标注了三个像素单元组141、142和143，在该行方向上，还包 括多个开口面积相同的像素单元构成的像素单元组。每行子像素中，从靠近行方向上的中点105位置处向远离行方向上的中点105位置处，像素单元组14的开口面积逐渐减小。例如，像素单元组14的开口面积呈等差数列减小。例如，每个像素单元组包括两个像素单元。需要说明的是，每个像素单元组还可包括两个以上的像素单元。
例如，在本实施例中，在列方向上，同一列中各个子像素的开口面积可以是相同的。例如，在每一行子像素中，各个子像素是等高的；在不同行中，各个子像素也是等高的。开口面积的变化可以通过子像素宽度的变化来调整。
本实施例中，图3a为阵列基板，图3b为彩膜基板，相关描述可参考实施例1中有关阵列基板和彩膜基板的描述，在此不再赘述。
实施例3
本实施例与实施例1和2的区别在于：在列方向上，用于显示同一颜色的各个子像素的开口面积可以是不相同的。在行方向上用于显示同一颜色的各子像素可参照实施例1和2的叙述。在行方向上的各像素单元可参见实施例1和2的叙述。
例如，在本实施例提供的显示基板中，如图4a、4b所示，每列子像素包括第三子像素P3和第四子像素P4且该列子像素形成的线段在列方向上具有中点106(或者该列子像素中用于显示同一颜色的子像素单元形成的线段在列方向上具有中点106)，第三子像素P3和第四子像素P4用于显示同一颜色，第三子像素P3到列方向上的中点106的距离小于第四子像素P4到列方向上的中点106的距离，第三子像素P3的开口面积大于第四子像素P4的开口面积。
需要说明的是，本公开中，列方向上的中点为每列子像素形成的线段在列方向上位于中间位置的一个抽象的点，以方便描述，而不是该显示基板中客观存在的具体结构。类似地，第三子像素和第四子像素也以其相对于列方向上的中点距离的大小而定义，而非特指某一位置的某个子像素。并且，第三子像素P3和第四子像素P4并不限于位于每列子像素形成的线段的中点106的同一侧，第三子像素P3和第四子像素P4可位于每列子像素形成的线段的中点106的两侧。
例如，在本实施例的一个示例中，如图4a、4b所示，每列子像素中，从 靠近列方向上的中点106位置处向远离列方向上的中点106位置处，用于显示同一颜色的各子像素单元101的开口面积逐渐减小。
例如，在本实施例的一个示例中，如图4a、4b所示，每列子像素中，从靠近列方向上的中点106位置处向远离列方向上的中点106位置处，用于显示同一颜色的各子像素的开口面积呈等差数列减小。例如，此处等差数列的公差可参见实施例1中的叙述。K的数值亦可参见实施例1中的叙述。公差以及K值可与实施例1中的相同。
因彼此紧邻的用于显示同一颜色的子像素的开口面积逐渐减小，则各相邻的用于显示同一颜色的子像素的亮度也是逐渐减小的。从而使得兼顾画面均一性的同时使中心区域亮度提升，且每一列不同位置处亮度差异逐渐变化，以取得较好的视觉效果。
例如，在本实施例的一个示例中，每列子像素中，开口面积最小的子像素单元与用于显示同一颜色的开口面积最大的子像素单元的开口面积的比值大于等于0.8小于1。
例如，在本实施例的一个示例中，如图4a、4b所示，每列子像素中，第三子像素P3和第四子像素P4为彼此紧邻的用于显示同一颜色的子像素。

在实施例1或2中，“行”替换为“列”，“行方向”替换为“列方向”的情况下，本实施例中的“列”替换为“行”，“列方向”替换为“行方向”实施例4中可与此相同。
实施例4
本实施例与实施例3的区别在于：每列子像素中，第三子像素P3和第四子像素P4并非为彼此紧邻的用于显示同一颜色的子像素，如图5a、5b所示，在第三子像素P3和第四子像素P4之间还可设有与第三子像素P3和第四子像素P4显示同一颜色的至少一个中间子像素P5。第三子像素P3和第四子像素P4位于列方向上的中点106的同一侧，至少一个中间子像素P5的开 口面积与第三子像素P3或第四子像素P4的开口面积相同。
图5a、5b中以第三子像素P3和第四子像素P4之间还设有与第三子像素P3和第四子像素P4显示同一颜色的一个中间子像素P5且中间子像素P5的开口面积与第四子像素P4的开口面积相同与为例进行说明。中间子像素P5的个数还可以大于一个。并且，中间子像素P5的开口面积还可以与第三子像素P3的开口面积相同。
如图5a、5b所示，相邻的开口面积相同的多个用于显示同一颜色的子像素为一个子像素单元组15，图中标注了两个子像素单元组151和152，在该列方向上，还包括多个开口面积相同的用于显示同一颜色的子像素构成的子像素单元组，每列子像素中，从靠近列方向上的中点106位置处向远离列方向上的中点106位置处，用于显示同一颜色的子像素单元组15的开口面积逐渐减小。例如，用于显示同一颜色的子像素单元组15的开口面积呈等差数列减小。例如，此处等差数列的公差可参见实施例1中的叙述。K的数值亦可参见实施例1中的叙述。公差以及K值可与实施例1中的相同。例如，每个子像素单元组中包含相同个数的用于显示同一颜色的子像素。

实施例5
本实施例提供一种显示面板，包括上述任一实施例的显示基板。
例如，该显示面板为液晶显示面板或有机发光二极管显示面板。对于液晶显示面板，彩膜基板上的子像素布置与阵列基板上的子像素布置是彼此对应的，因此彩膜基板和阵列基板之一采用如上所述任一实施例的方案，则另一个也相应地采用该实施例的方案。
因本实施例的显示面板包括上述任一实施例的显示基板，故而其可具有与其包含的显示基板相同的效果。
例如，液晶显示面板中，背光模组(BLU)的功耗通常占据液晶模组(LCM)整体功耗的70％以上。提升面板透过率是降低背光模组功耗的最有效方式之一。本发明任一实施例提供的显示基板用于液晶显示面板中的情况下，可在不增加背景光源功率的情况下，使重要显示区域(中心位置)具有更好的显示效果，可提升显示面板中心区域的透过率，从而提升中心区域的 亮度、降低功耗。
