具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所述领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
在对本公开实施例的像素阵列和显示装置描述之前，对下述描述中所提及的子像素、第一子像素、第二子像素、第三子像素等概念进行说明。在本公开实施例中，子像素指代的是发光器件结构，第一子像素、第二子像素、第三子像素则代表三种不同颜色的子像素。其中，在本公开实施例中以第一子像素为红色子像素，第二子像素为绿色子像素，第三子像素为蓝色子像素为例进行说明。但第一子像素为红色子像素，第二子像素为绿色子像素，第三子像素为蓝色子像素并不构成对本公开实施例保护范围的限制。
通常决定各个子像素形状的是像素限定层中的开口，发光层形成在开口中，则限定出了该子像素的发光区的形状，也即在本公开实施例中所指的子像素的形状。例如，当开口为四边形时，该子像素则为四边形。
如图1所示为相关技术中一种像素排布示意图。如图1所示，包括三种颜色的子像素，例如红色第一子像素11、绿色第二子像素12和蓝色第三子像素13，这三种颜色的子像素例如以金刚石(Diamond)结构排布。但是，如何提高目前该金刚石排布的子像素的开口率从而提高显示装置的分辨率是业界亟待解决的问题。
由此，根据本公开的一个方面，提供了一种像素阵列。图2为根据本公开的实施例的像素阵列示意图。如图2所示，该像素阵列包括具有第一颜色的多个第一子像素11、具有第二颜色的多个第二子像素12、和具有第三颜色的多个第三子像素13。本公开以第一颜色为红色、第二颜色为绿色和第三颜色为蓝色为例进行说明，但本公开不限于此。
如图2所示，第一子像素11和第三子像素13沿第一方向D1交替设置以形成多个第一子像素行101，第二子像素12沿第一方向D1设置以形成多个第二子像素行102。多个第一子像素行101和多个第二子像素行102沿第二方向D2交替设置。并且，第一子像素12和第三子像素13还沿第二方向D2交替设置以形成多个第一子像素列201，第二子像素12还沿第二方向D2设置以形成多个第二子像素列202。多个第一子像素列201和多个第二子像素列202沿第一方向D1交替设置。第二方向D2不同于第一方向D1。可选地，第二方向D2垂直于第一方向D1。
具体地，如图2所示，第一子像素11和第三像素13沿行方向(第一方向D1)并且沿列方向(第二方向D2)交替排列，并形成相应的第一子像素行101和第一子像素列201；第二子像素12沿行方向(第一方向D1)并且沿列方向(第二方向D2)交替排列，并形成相应的第二子像素行102和第二子像素列202。第一子像素行101可设置为奇数行，第二子像素行102可设置为偶数行，或者，第一子像素行101可设置为偶数行，第二子像素行102可设置为奇数行。第一子像素列201可设置为奇数列，第二子像素列202可设置为偶数列，或者，第一子像素列201可设置为偶数列，第二子像素列202可设置为奇数列。
如图2所示，多个第二子像素12中的至少一个第二子像素12的至少一部分被设置为向其内部凹陷，多个第一子像素11中的至少一个第一子像素11的至少一部分被设置为向其内部凹陷,并且与该至少一个第二子像素12相邻的多个第三子像素13中的至少一个被设置为与至少一个第二子像素12的凹陷对应、沿远离至少一个第三子像素13的内部的方向凸起。此处的凹陷指的是第一子像素11和第二子像素12的至少一部分相对于其它部分向其内部突出，使得该至少一部分相对于其它部分向其内部凹陷。通过使得第二子像素12向其内部凹陷，可以使得其面积减少；通过使得第三子像素13相对于该至少一个第二子像素12的凹陷的部分凸起，可以使得第三子像素13的面积增大。尤其是使得寿命最短的蓝色第三子像素13的面积增大，可以延长显示面板的寿命，但本公开不限于。可选地，也可以将与该至少一个第二子像素12相邻的多个第一子像素11中的至少一个被设置为向其内部凹陷对应，减小第一子像素11的面积，进而增加可设置第三子像素13的面积。
可选地，如图2所示，位于多个第一子像素行101中的相邻两个第一子像素行中并且多个第一子像素列201中的相邻两个第一子像素列中的两个第一子像素11的中心和两个第三子像素13的中心的依次连线构成第一虚拟正方形。如图2所示，多个第二子像素12中的一个位于第一虚拟正方形的中心，两个第一子像素11的中心和两个第三子像素13的中心分别位于第一虚拟正方形的四个顶点。
多个第二子像素12中的至少一个包括分别与相邻第三子像素13靠近的并且相对设置的第一边121和第二边122，第一边121和第二边122沿第一虚拟正方形中的第二子像素12的中心与相邻第三子像素13的中心的连线方向对称设置，并且第一虚拟正方形中的第二子像素12的中心与相邻第三子像素13的中心的连线穿过第一边121和第二边133的中心。第一边121和第二边122的中心沿第一虚拟正方形中的第二子像素12的中心与相邻第三子像素13的中心的连线方向、相对于第一边121和第二边122除中心之外的其它点靠近第一虚拟正方形中的第二子像素12的中心。也就是说，第一边121和第二边沿第一虚拟正方形中的第二子像素12的中心与相邻第三子像素13的中心的连线方向向该的第二子像素12的内 部凹陷。
如图2所示，由上述设置形成的第二子像素12的形状类似“骨头”形，导致本公开的第二(绿色)子像素12的开口率(或面积)小于图1所示的相关技术中的第二(绿色)子像素的开口率，进而可以增大与第二子像素12相邻的寿命最短的第三(蓝色)子像素13的开口率，可以提高蓝色子像素的寿命。
如图2所示，在第一虚拟正方形SQ1内，第二子像素12与相邻第三子像素13的中心连线沿第三方向D3延伸；在与第一虚拟正方形SQ1相邻的第一虚拟正方形SQ2内，第二子像素12与相邻第三子像素13的中心连线沿第四方向D4延伸。第三方向D3与第四方向D4交叉并且不同于第一方向D1和第二方向D2。也就是说，一个第三子像素13的周围设置有四个第二子像素12，并且这四个第二子像素12中的两个沿第三方向D3分别设置在该第三子像素13的两侧，另外两个沿第四方向D4分别设置在该第三子像素13的两侧。同理，一个第一子像素11的周围也设置有四个第二子像素12，并且沿第三方向D3在该第一子像素11的相对两侧分别设置有一个第二子像素12，沿第四方向D4在该第一子像素11的相对两侧分别设置有一个第二子像素12。相应地，第三子像素13沿第三方向D3和沿第四方向D4对应于相邻第二子像素12的凹陷而沿远离第三子像素13内部的方向凸起(如图2中虚线A所示)，从而增加第三子像素13的开口率。
