 有益效果
与现有技术相比，本申请具有以下优点：
本申请所提供的显示面板，主要设置了由多个挡墙块排布所形成的挡墙阵列，挡墙阵列中不同排布阵列所形成的间隙沿远离显示区域的方向延伸并且彼此相互错开，相较于传统方式，由于流动性有机材料需要流动过彼此错开的不同间隙才能移动至周边区域的边缘，所以流动性有机材料于周边区域当中流动路径被延长，使得流动性有机材料最终流动截止位置容易处于堤坝墙以内，从而降低了流动性有机材料在喷墨打印阶段越过堤坝墙的风险以及显示面板封装失效的风险。

实施例1
本实施例的主体是一种显示面板，具体是一种OLED显示面板，但并不限制于此，显示面板可以是任意一种需要喷墨打印有机膜层形成封装结构的显示面板，本申请对此不做特别限定。
请参见图1和图2，在本实施例中，上述显示面板包括：
显示基板10，显示基板10形成有显示区域11和至少形成于显示区域11一侧外的周边区域12；
挡墙部，挡墙部设置于周边区域12，挡墙部包括堤坝墙21和由多个挡墙块排布所形成的挡墙阵列，堤坝墙21处于挡墙阵列远离于显示区域11一侧，挡墙阵列包括至少两组沿远离显示区域11的方向依次设置的排布阵列，每一排布阵列中相邻两挡墙块之间形成沿远离显示区域11的方向延伸的间隙，存在于至少两组排布阵列中的间隙彼此错开。
在对上述显示基板10进行喷墨打印以形成有机膜层，从而构成封装结构的过程当中。流动性有机材料会由显示区域11进入至周边区域12当中，大致呈沿远离显示区域11的方向流动。请参见图1，由于挡墙阵列中的各个排布阵列是沿着远离显示区域11的方向依次排布。所以，流动性有机材料会依次通过各个排布阵列中挡墙块所形成的间隙，而最终抵达堤坝墙21附近。请参见图2和图4，其中带有箭头的曲线线条指代为流动性有机材料的流动路径，带有箭头的直线线条指代为远离显示区域11的方向，流动性有机材料在通过各个排布阵列挡墙块所形成的间隙时，由于不同排布阵列中的挡墙块所形成的间隙彼此错开，所以流动性有机材料的流动路径呈现为曲折状，这会提升流动性有机材料的流动路径长度，进而使得流动性有机材料最终流动截止位置更加容易处于堤坝墙21以内，从而降低了流动性有机材料在喷墨打印阶段越过堤坝墙21的风险以及显示面板封装失效的风险，尤其适用于显示面板采用窄边框设计、周边区域12较短的情形。
另外，请参见图7，在传统方式当中，由于流动性有机材料于显示区域11和周边区域12的流动性能并不相同，所以流动性有机材料于周边区域12所形成的有机膜层26大致呈靠近显示区域11一侧较厚并形成凸起，而远离显示区域11一侧较薄的形态，这会影响封装结构的光学性能以及后段工艺制程。而通过挡墙阵列则能够延长流动性有机材料的流动路径，并且由于最前侧的排布阵列的间隙能够起到一定引流作用，而较后侧的排布阵列的间隙错开，能够起到阻碍流动性有机材料流动的限流作用，避免有机膜层26靠近显示区域11一侧部位形成凸起或者边缘部位偏薄，进而有效改善上述有机膜层26的成型效果。
上述显示区域11即指显示基板10中对应进行发光显示的区域，而上述周边区域12即指处于显示区域11周边的区域。在本实施例中，上述显示区域11受到周边区域12的环绕。需要说明的是，这并不应当理解为对显示区域11以及周边区域12位置上的限制，周边区域12可以仅存在于显示区域11的一侧或者任意几侧之外。
还需要说明的是，实施人员可以依据自身需求而选择上述挡墙阵列中所包括的排布阵列数量，只要确保有两个排布阵列所形成的间隙相互错开，越过挡墙阵列的流动性有机材料的流动路径即不再会是笔直形状，即可起到延长流动性有机材料流动路径的效果。
更为具体的，在本实施例中，显示基板10具体为阵列基板，其还可以是需要设置封装结构的玻璃盖板等结构。上述堤坝墙21呈环绕显示区域11的封闭形状并且其数目为一道，但堤坝墙21的数量以及堤坝墙21的形状并不限制于此。在不影响发明目的的情况下，实施人员可以选择堤坝墙21的数目以及其形状。例如，在另一实施例中，上述堤坝墙21的数目为两道，并且呈非封闭形状。
请参见图2，为简化挡墙阵列的设置方式，在本实施例中，挡墙块包括第一挡墙块221和第二挡墙块231，排布阵列包括由多个第一挡墙块221依次排布所形成的第一排布阵列22，以及由多个第二挡墙块231依次排布所形成的第二排布阵列23，第一排布阵列22和第二排布阵列23沿远离于显示区域11的方向依次设置。
也就是说，本实施例主要采用了两组排布排阵列，以分别形成两种不同并且彼此间相互错开的间隙，来达到延伸流动性有机材料的流动路径的目的。相较于更多排布阵列的技术方案，本实施例所提供的技术方案更加容易进行实施。
这里需要说明的，间隙包括形成于相邻两第一挡墙块221之间的第一间隙221d以及形成于相邻两第二挡墙块231之间的第二间隙231d，第一间隙221d和第二间隙231d彼此错开，但这并不理当理解为第一排布阵列22和第二排布阵列23必须相邻设置。正如前文当中所描述的，对于第一排布阵列22和第二排布阵列23而言，两者之间可以存在有其他阵列，两者的外侧也可以存在有其他阵列，只要第一间隙221d和第二间隙231d错开即可。
另外，正如前文当中所描述的，由于流动性有机材料于显示区域11和周边区域12的流动性能并不相同，所以流动性有机材料于周边区域12所形成的有机膜层26大致呈靠近显示区域11一侧较厚并形成凸起，而远离显示区域11一侧较薄的形态。对应于此，请参见再次参见图2并结合图4，在本实施例中，在远离于显示区域11的方向上，第一间隙221d的宽度逐渐缩小。
随着第一间隙221d的宽度逐渐缩小，流动性有机材料在通过第一间隙221d的过程当中，会呈现为流动速度逐渐加快的形态，这会降低流动性有机材料堆叠于第一间隙221d处的风险。而由于第一间隙221d在整个挡墙部中处于靠近显示区域11一侧，所以能够有效降低有机膜层26于靠近显示区域11一侧形成凸起的风险。这里，需要说明的是，本领域技术人员可以理解，第一间隙221d的宽度方向即指垂直于第一间隙221d延伸方向以及正方向的方向。这里所指的正方向即指垂直于显示基板10的方向。
另外，实施人员可以依据自身需求而调整上述第一挡墙块221的形状以及高度。但如果期望第一间隙221d的宽度在远离于显示区域11的方向上逐渐减小，则可以使得相邻两第一挡墙块221朝向彼此的侧边中，至少存在有一者在远离显示区域11方向上逐步靠近另一者延伸。理想的是，如本实施例中展示的，在相邻两第一挡墙块221朝向彼此的侧边中，两者在远离于显示区域11的方向上沿直线延伸。也就是说，界定出第一间隙221d的两侧侧边均为直边，这样设置能够方便第一挡墙块221的成型。
更为具体的，请结合图2和图3，第一挡墙块221朝向其两侧相邻第一挡墙块221的侧边分别为第一侧边221a和第二侧边221b；
在至少部分第一挡墙块221中，第一侧边221a和第二侧边221b相连，并且在远离于显示区域11的方向上，第一侧边221a和第二侧边221b自两者相连的部位背向于彼此地倾斜延伸；和/或，
在至少部分第一挡墙块221中，第一侧边221a和第二侧边221b通过设置于两者之间的第一直边221c相连，并且在远离于显示区域11的方向上，第一侧边221a和第二侧边221b自其与第一直边221c相连部位背向于彼此地倾斜延伸。
也就是说，部分第一挡墙块221上可以形成使得第一侧边221a、第二侧边221b直接相连的角端部结构，部分第一挡墙块221也可以形成使得第一侧边221a、第二侧边221b通过第一直边221c相连的梯形端部结构。如此设置，能够进一步改善流动性有机材料于第一排布阵列22处的分流、引流效果，降低流动材料的流动性损失，降低流动性有机材料于周边区域12靠近显示区域11一侧形成凸起的风险。
需要说明的是，实施人员可以如本实施例中所展示的，将第一挡墙块221设置成其在垂直于正方向的截面上呈三角形，但这并不应当理解为在第一挡墙块221具有如上所描述的角端部结构时，第一挡墙块221的截面必须是三角形并且第一侧边221a和第二侧边221b必须为直边。第一挡墙块221可以是包括有角端部结构的任意形状，同时，第一侧边221a、第二侧边221b也可以为弧形边，只要第一挡墙块221能够包括如上所描述的角端部结构，即能够提升第一挡墙块221的分流效果。
还需要说明是，对于第一排布阵列22中的第一挡墙块221，可以是部分第一挡墙块221具有如上所描述的角端部，部分第一挡墙块221具有如上所描述的梯形端部，还可以如图4中另一实施例所展示的，全部第一挡墙块221具有如上所描述的梯形端部，也可以如本实施例中所展示的，全部第一挡墙块221在垂直于正方向的截面上呈三角形，所有第一挡墙块221均具有如上所描述的角端部，本申请对此不做特别限定。
进一步的，正如前文当中所描述的，流动性有机材料于周边区域12所形成的有机膜层26大致呈靠近显示区域11一侧较厚并形成凸起，而远离显示区域11一侧较薄的形态，通过对第一间隙221d宽度的改进能够有效改善有机膜层26靠近显示区域11一侧形成凸起的问题。对应于流动性有机材料固化后所形成有机膜层26远离显示区域11一侧较薄的问题，请再次结合图2和图4，在本实施例中，在远离显示区域11方向上，第二间隙231d的宽度逐渐增大。其中，通过增大第二间隙231d的宽度能够使得流动性有机材料于此处的流动速度逐渐减缓，起到一定程度的限流作用。同时，由于第二挡墙块231所形成的第二排布阵列23处于第一排布阵列22的外侧，所以能够有效改善流动性有机材料于周边区域12远离显示区域11一侧所形成膜层厚度较薄的问题。
与前文所描述结构类似的，在本实施例中，在相邻两第二挡墙块231朝向彼此的侧边中，至少存在有一者在远离于显示区域11的方向上逐步背离于另一者且呈直线延伸。也就是说，界定出第二间隙231d的两侧侧边均呈直边形状，这样设置能够方便第二挡墙块231成型。
详细的，在本实施例中，第二挡墙块231朝向其两侧相邻第二挡墙块231的侧边分别为第三侧边231a和第四侧边231b；在至少部分第二挡墙块231中，第三侧边231a和第四侧边231b通过设置于两者之间的第二直边231c相连，并且在远离于显示区域11的方向上，第三侧边231a和第四侧边231b自其与第二直边231c相连接部位相向于彼此地延伸，以方便第二挡墙块231成型。更为具体的，在本实施例中，第二挡墙块231垂直于正方向的截面呈三角形，并且其顶角部位指向于远离显示区域11一侧，当然，实施人员也可以将上述第二挡墙块231设置成：垂直于正方向的截面呈较小端指向于远离显示区域11一侧的梯形。
下面将进一步对本实施例所提供显示面板中部件的具体尺寸做进一步介绍，请参见图4，在本实施例中，第一挡墙块221和第二挡墙块231的形状大小一致，第一排布阵列22中央距离堤坝墙21的间距为e1，而第二排布阵列23中央距离堤坝墙21的间距为e2，显示区域11边缘至堤坝墙21的间距为a，a即是流平区域尺寸。b1为第一挡墙块221、第二挡墙块231的宽度尺寸，d1为第一挡墙块221、第二挡墙块231在远离显示区域11方向上的长度尺寸。其中，e2的范围可以为（d1/2+10）um至a/2，而e1-e2-d1的尺寸可以在5um至1200um之间选择。b1的范围为1um至1200um，c1的范围为1um至1200um。实施人员可以在不影响发明目的以及不发生干涉的前提下，进行选取。这里需要说明的是，在第一挡墙块221包括如前文中所描述的梯形端部，并且在第一挡墙块221垂直于正方向的截面呈梯形时，第一挡墙块221以及第二挡墙块231较小端和较大端的长度之比的范围可以选择在0.1至0.9。
进一步的，关于挡墙阵列的成型步骤，在本实施例中，于阵列基板的制作工艺中，在周边区域12中，应用掩膜以图案化形成以挡墙阵列。当然，在不影响发明目的的前提下，实施人员还可以采用蒸镀等其他工艺成型上述挡墙阵列。
实施例2
实施例2提供了一种显示面板，请参见图5，本实施例与实施例1的主要区别点在于：实施例2中，第一挡墙块221、第二挡墙块231垂直于正方向的截面均呈矩形，以方便第一挡墙块221和第二挡墙块231的成型。
下面将进一步对本实施例所提供显示面板中部件的具体尺寸做进一步介绍，在本实施例中，B1为第一排布阵列22中第一挡墙块221的宽度，D1为第一挡墙块221在远离显示区域11方向上的尺寸，B2为第二排布阵列23中第二挡墙块231的宽度，D2为第二挡墙块231在远离显示区域11方向上的尺寸，C1为第一排布阵列22中相邻两个第一挡墙块221之间的间距，C2为第二排布阵列23中相邻两个第二挡墙块231之间的间距。其中，第一排布阵列22距离堤坝墙21的间距为e1，而第二排布阵列23距离堤坝墙21的间距为e2，e1和e2可以选择至与实施例1中的e1和e2具有相同的数值范围。另外，B2的范围可以选择为29um至1200um，并且D2≤B2，B1的范围可以为（B2-10um）至B2/2，并且D1≤B1，C1的范围为1um至1200um，并且C2≤C1。实施人员可以在不影响发明目的以及不发生干涉的前提下，进行选取。
实施例3
实施例3提供了一种显示面板，本实施例所提供的技术方案与实施例1的技术方案大致相同。其中，请结合图1和图6，对于实施例1所提供的技术方案而言，由于显示区域11主要由多道依次呈夹角相连的边沿所界定，所以第一排布阵列22或者第二排布阵列23可以分为多道与显示区域11侧边相对应的边沿列24，而在相邻两边沿列24的交汇处，即显示区域11的对角外侧，流动性有机材料的流动路径可能会呈笔直延伸的形状，其长度较短，流动性有机材料容易于堤坝墙21角落处溢出。
所以，请参见图7，排布阵列于对角处的结构示意图，在本实施例中，排布阵列分为多道沿环绕显示区域11的方向依次设置并与显示区域12的边沿相对应的边沿列24，挡墙部还包括阻流结构25，阻流结构25设置于相邻两边沿列24最靠近彼此的挡墙块之间。
其中，流动性有机材料在通过阻流结构25的时候，会沿阻流结构25的外壁进行流动，其流动路径的长度被拉长，并使流动性有机材料具有着朝两侧边沿列24移动的趋势，减弱流动性有机材料沿对角方向流动的趋势。其中，理想的是：将阻流结构25设置成其垂直于正方向的截面呈圆形，其中，阻流结构25的外周面能够有效降低流动性有机材料的流动性损失，避免流动性有机材料堆积于阻流结构25处，尤其适用于流动性有机材料粘度较高的情形。
实施例4
实施例4提供了一种显示装置，包括如实施例1、实施例2或者实施例3中任意一实施例所描述的显示面板，上述显示装置可以是平板电脑、VR、手机以及笔记本电脑等等任意显示装置。
上文已对基本概念做了描述，显然，对于本领域技术人员来说，上述详细披露仅仅作为示例，而并不构成对本申请的限定。虽然此处并没有明确说明，本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议，所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
同时，本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一个替代性实施例”并不一定是指同一实施例。此外，本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
同理，应当注意的是，为了简化本申请披露的表述，从而帮助对一个或多个发明实施例的理解，前文对本申请实施例的描述中，有时会将多种特征归并至一个实施例、附图或对其的描述中。但是，这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字，应当理解的是，此类用于实施例描述的数字，在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明，“大约”、“近似”或“大体上”表明数字允许有±%的变化。相应地，在一些实施例中，说明书和权利要求中使用的数值参数均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中用于确认其范围广度的数值域和参数为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
针对本申请引用的每个专利、专利申请、专利申请公开物和其他材料，如文章、书籍、说明书、出版物、文档等，特此将其全部内容并入本申请作为参考，但与本申请内容不一致或产生冲突的申请历史文件除外，对本申请权利要求最广范围有限制的文件（当前或之后附加于本申请中的）也除外。需要说明的是，如果本申请附属材料中的描述、定义、和/或术语的使用与本申请内容有不一致或冲突的地方，以本申请的描述、定义和/或术语的使用为准。
