具体实施方式
大尺寸高PPI透明显示的一个瓶颈在于，随着PPI增大，像素尺寸变小，金属走线密度增大，透明区面积减小，在影响透过率的同时，更容易发生小孔衍射效应，反映在实际体验中即透过显示基板看到的物体有重影现象，严重影响了客户体验。
因此，如何减小大尺寸高PPI显示基板的衍射重影现象，是目前亟待解决的技术问题。
为使本公开的上述目的、特征和优点能够更为明显易懂，下面将结合附图和实施例对本公开做进一步说明。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本公开更全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。在图中相同的附图标记表示相同或类似的结构，因而将省略对它们的重复描述。本公开中所描述的表达位置与方向的词，均是以附图为例进行的说明，但根据需要也可以做出改变，所做改变均包含在本公开保护范围内。本公开的附图仅用于示意相对位置关系不代表真实比例。
需要说明的是，在以下描述中阐述了具体细节以便于充分理解本公开。但是本公开能够以多种不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本公开内涵的情况下做类似推广。因此本公开不受下面公开的具体实施方式的限制。说明书后续描述为实施本公开的较佳实施方式，然所述描述乃以说明本公开的一般原则为目的，并非用以限定本公开的范围。本公开的保护范围当视所附权利要求所界定者为准。
下面结合附图，对本公开实施例提供的显示基板及显示装置进行具体说明。
本公开实施例提供的一种显示基板，如图1a和图1b所示，其中，图1b为图1a所示的显示基板中一个像素重复单元组的结构示意图；显示基板包括沿第一方向X依次排列的多个像素重复组1，每一像素重复组1包括沿第二方向Y排列的多个像素重复单元10；
每一像素重复单元10包括沿第一方向X排列设置的两个像素区域P1和P2以及位于两个像素区域P1和P2之间的透光区域T；其中：
像素区域P1和P2中均设置有至少三个相邻设置的子像素(图1a和图1b中的A、B和C)；
透光区域T的面积等于单个像素区域P1或P2对应的透光区域的面积的 两倍，其中，单个像素区域P1或P2对应的透光区域的面积等于显示基板中所有透光区域的总面积除以显示基板中所有像素区域的数量。
本公开实施例提供的显示基板，在每一像素重复单元中包括沿第一方向排列设置的两个像素区域以及位于两个像素区域之间的透光区域；其中，像素区域设置有至少三个相邻设置的子像素；透光区域的面积等于单个像素区域对应的透光区域的面积的两倍。相当于将相关技术中两个像素区域分别对应的透光区域拼接在一起放置于两个像素区域之间，在不增加显示基板中透光区域总面积的基础上，使显示面板中每一个独立分布的透光区域的面积增加至现有显示基板中单个透光区域的面积的两倍，从而减轻显示基板的衍射现象，改善重影问题。
需要说明的是，在本公开实施例提供的显示基板中，一个像素区域对应设置有一个像素，因此显示基板中像素区域的数量就是该显示基板中像素的数量。
在具体实施时，在本公开实施例中，第一方向与第二方向交叉。其中，第一方向可以为行方向，第二方向为列方向，或者第一方向可以为列方向，第二方向为行方向，在此不作限定。本公开说明书附图均以第一方向为行方向，第二方向为列方向为例进行示意。
可选地，在本公开实施例提供的显示基板中，如图2a-图2b，图3a-图3b，图4a-图4b，图5a-图5b，图6a-图6b，图7a-图7b，图8a-图8b，图9a-图9b所示，在每一像素重复单元10中，像素区域P1和P2与透光区域T的交界线均呈折线，使得在像素重复组1中，由各像素重复单元10中的透光区域T拼接起来的独立的透光区域的边界线是折线，从而在一定程度上改变小孔衍射的光路径，进一步弱化小孔衍射现象。
在具体实施时，在本公开实施例提供的显示基板中，对于沿第一方向相邻的任意两个像素重复组，分别属于该两个像素重复组中的相邻像素区域的边界形状相匹配，从而保证相邻像素重复组中的子像素能够紧密排列，也可以认为分别属于相邻两个像素重复组中的相邻像素区域的子像素相互连接。
可选地，在本公开实施例提供的显示基板中，如图2a-图2b，图3a-图3b，图4a-图4b，图5a-图5b所示，在各像素重复单元10中，像素区域P1和P2均包括第一子像素A、第二子像素B和第三子像素C，且3个子像素之间的中心连线构成三角形。这样设置可以使像素区域P1和P2与透光区域T的交界线均呈折线。
可选地，在本公开实施例提供的显示基板中，如图2a、图2b、图4a和图4b所示，其中，图2b为图2a所示的显示基板中一个像素重复单元的结构示意图，图4b为图4a所示的显示基板中一个像素重复单元的结构示意图；在像素重复单元10中，像素区域P1和P2中3个子像素排列为：第一子像素A和第二子像素B沿第一方向X相邻设置，第三子像素C与第一子像素A沿第二方向Y相邻设置，第二子像素B和第三子像素C均与透光区域T沿第一方向X相邻设置。
可选地，在本公开实施例提供的显示基板中，如图3a、图3b、图5a和图5b所示，其中，图3b为图3a所示的显示基板中一个像素重复单元的结构示意图，图5b为图5a所示的显示基板中一个像素重复单元的结构示意图；在像素重复单元10中，其中：
一个像素区域P1中3个子像素排列为：第一子像素A和第二子像素B沿第一方向X相邻设置，第三子像素C与第一子像素A沿第二方向Y相邻设置，第二子像素B和第三子像素C均与透光区域T沿第一方向X相邻设置；
另一个像素区域P2中3个子像素排列为：第一子像素A和第二子像素B沿第一方向X相邻设置，第三子像素C与第二子像素B沿第二方向Y相邻设置，第一子像素A和第三子像素C均与透光区域T沿第一方向X相邻设置。
可选地，在本公开实施例提供的显示基板中，如图4a、图4b、图5a和图5b所示，像素重复单元10中，其中一个像素区域P1中的第三子像素C与另一像素区域P2中的第一子像素A和第二子像素B沿第一方向X排列设置。这样既可以保证每一子像素行中透明区域所占的面积相同，又可以保证每一子像素行中子像素的数量相同，从而保证显示品质。
可选地，在本公实施例提供的显示基板中，如图10a和图10b所示，在像素重复单元10中，像素区域P1和P2中3个子像素排列为：第三子像素C与第一子像素A沿第二方向Y相邻设置，第二子像素B分别与第一子像素A和第三子像素C沿第一方向X相邻设置，第一子像素A、第二子像素B和第三子像素C均与透光区域T沿第一方向相邻设置。
可选地，在本公实施例提供的显示基板中，如图10c和图10d所示，在像素重复单元10中，其中：
一个像素区域P1中3个子像素排列为：第三子像素C与第一子像素A沿第二方向Y相邻设置，第二子像素B分别与第一子像素A和第三子像素C沿第一方向X相邻设置，第一子像素A、第二子像素B和第三子像素C均与透光区域T沿第一方向X相邻设置；
另一个像素区域P2中3个子像素排列为：第三子像素C与第二子像素B沿第二方向Y相邻设置，第一子像素A分别与第二子像素B和第三子像素C沿第一方向X相邻设置，第一子像素A、第二子像素B和第三子像素C均与透光区域T沿第一方向X相邻设置。
可选地，在本公开实施例提供的显示基板中，如图6a-图6b，图7a-图7b，图8a-图8b，图9a-图9b所示，中，图6b为图6a所示的显示基板中一个像素重复单元的结构示意图，图7b为图7a所示的显示基板中一个像素重复单元的结构示意图，图8b为图8a所示的显示基板中一个像素重复单元的结构示意图，图9b为图9a所示的显示基板中一个像素重复单元的结构示意图；像素区域P1和P2均包括第一子像素A、第二子像素B、第三子像素C和第四子像素D，且4个子像素之间的中心连线构成平行四边形。这样设置可以使像素区域P1和P2与透光区域T的交界线均呈折线。
可选地，在本公开实施例提供的显示基板中，如图6a-图6b，图7a-图7b，图8a-图8b，图9a-图9b所示，像素重复单元10中，像素区域P1和P2中4个子像素排列均为：第一子像素A和第二子像素B沿第一方向X相邻设置，第三子像素C与第四子像素D沿第一方向X相邻设置。
可选地，在本公开实施例提供的显示基板中，如图6a至图9b所示，在像素区域P1和P2中，第一子像素A和第二子像素B中的其中一个子像素，与第三子像素C和第四子像素D中的其中一个子像素沿第二方向Y相邻设置；第一子像素A和第二子像素B中的另一个子像素，与第三子像素C和第四子像素D中的另一个子像素错开设置。例如，在像素区域P1或P2中，第一子像素A与第三子像素C沿第二方向Y相邻设置，第二子像素B与第四子像素D不相邻；第一子像素A与第四子像素D沿第二方向Y相邻设置，第二子像素B与第三子像素C不相邻；第二子像素B与第三子像素C沿第二方向Y相邻设置，第一子像素A与第四子像素D不相邻；第二子像素B与第四子像素D沿第二方向Y相邻设置，第一子像素A与第三子像素C不相邻。
可选地，在本公开实施例提供的显示基板中，如图7a-图7b，图8a-图8b，图9a-图9b所示，像素重复单元10中，其中一个像素区域P1和P2中的第三子像素C与另一像素区域P1和P2中的第二子像素B沿第一方向X排列设置。这样既可以保证同一子像素行中，不同颜色的子像素的数量相同，又可以保证沿第一方向相邻设置的子像素的颜色不相同，从而保证显示品质。
在具体实施时，在本公开实施例提供的显示基板中，第一子像素、第二子像素和第三子像素的颜色不同，可以分别是红色子像素、蓝色子像素和绿色子像素，第四子像素可以是白色子像素或者黄色子像素等，第四子像素也可以是红色子像素、蓝色子像素和绿色子像素中的任一种，例如可以是蓝色子像素，在此不作限定。即第一子像素、第二子像素、第三子像素和第四子像素之中的两个子像素为发光颜色相同的子像素。
在具体实施时，本公开实施例提供的显示基板可应用于车载、智能家居、商店橱窗等任何具有透明显示功能的产品或部件，在此不作限定。
基于同一发明构思，本公开实施例还提供了一种显示装置，包括本公开实施例提供的上述任一种显示基板。由于该显示装置解决问题的原理与前述一种显示基板相似，因此该显示装置的实施可以参见上述显示基板的实施例，重复之处不再赘述。
本公开实施例提供的一种显示基板及显示装置，显示基板及显示装置，在每一像素重复单元中包括沿第一方向排列设置的两个像素区域以及位于两个像素区域之间的透光区域；其中，像素区域设置有至少三个相邻设置的子像素；透光区域的面积等于单个像素区域对应的透光区域的面积的两倍。相当于将相关技术中两个像素区域分别对应的透光区域拼接在一起放置于两个像素区域之间，在不增加显示基板中透光区域总面积的基础上，使显示面板中每一个独立分布的透光区域的面积增加至现有显示基板中单个透光区域的面积的两倍，从而减轻显示基板的衍射现象，改善重影问题。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
