具体实施方式
为了使得本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开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公开的一部分实施例，而不是全部的实施例。基 于所描述的本公开的实施例，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，都属于本公开保护的范围。
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属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。“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。
为了保持本公开实施例的以下说明清楚且简明，本公开省略了已知功能和已知部件的详细说明。
挖孔屏幕的开孔距屏幕边框有一个较窄的区域，因该区域距离较窄，导致通过喷墨打印形成有机封装层时，有机封装液体的流动区域相应缩窄，极其容易发生有机封装液体不能流平或段差较大的情况。有机封装液体未流平或段差较大在后续形成触控工艺过程中光刻胶涂覆不良发生，光刻胶从有机封装层较厚的区域流向有机封装层较薄的区域，导致一定区域内无光刻胶覆盖或光刻胶覆盖较薄。在进行显影刻蚀后，光刻胶缺失区域膜层将被完全刻蚀掉，导致触控膜层缺失、功能失效。
有鉴于此，本公开实施例提供一种显示面板，其中，包括：
衬底基板1，衬底基板1上设置有显示区AA，显示区AA包括第一显示区S1，显示区AA具有相对的第一边框11与第二边框12，连接第一边框11一端与第二边框12一端的第三边框13，以及连接第一边框11另一端与第二边框12另一端的第四边框14；
通孔K，通孔K贯穿衬底基板1，通孔K的中心O距离第一边框11的距离小于通孔K的中心O距离第二边框12的距离；具体的，例如，结合图1 所示，通孔K的中心O距离第一边框11的距离为h1，通孔K的中心O距离第二边框12的距离为h2，h1小于h2；
多个隔垫物2，多个隔垫物2位于衬底基板1的一侧，第一显示区S1包括通孔K与第一边框11之间的区域，第一显示区S1的隔垫物2分布密度大于通孔K与第二边框12之间的隔垫物分布密度。
本公开实施例中，第一显示区S1的隔垫物2分布密度大于通孔K与第二边框12之间的隔垫物分布密度，第一显示区S1隔垫物2分布密度的增大，使得有更多的隔垫物2参与引流，会加速后续形成的有机封装液体的流动性，有助于第一显示区S1后续形成的有机封装液体的流平，改善若有机封装液体未流平或段差较大时，在后续形成图案化的触控层时，光刻胶涂覆不良发生，光刻胶从有机封装层较厚的区域流向有机封装层较薄的区域，导致一定区域内无光刻胶覆盖或光刻胶覆盖较薄，在进行显影刻蚀后，光刻胶缺失区域，触控膜层将被完全刻蚀掉，导致触控膜层缺失、功能失效的问题。
在一种可能的实施方式中，衬底基板1的形状可以为矩形，在平行于矩形的短边方向上，通孔K可以位于中间的位置，具体的，结合图1所示，通孔K的中心O距离第三边框13的距离h3与通孔K的中心距离第四边框14的距离h4大致相等。
在一种可能的实施方式中，衬底基板1的形状可以为矩形，在平行于矩形的短边方向上，通孔K中心O距离第三边框13和第四边框14的距离也可以不同，例如，可以位于靠左侧的位置，或者，位于靠右侧的位置。在平行于矩形的短边方向上，将第三边框13、第四边框14中，通孔K中心O距离较近的一者作为第三边框13，较远的一者作为第四边框14，例如，参见图2所示，通孔K位于靠左侧的位置，将左侧边框作为第三边框13，即，通孔K的中心O距离第三边框13的距离h3小于通孔K的中心O距离第四边框14的距离h4，第一显示区S1还包括通孔K与第三边框13之间的区域，即，将通孔K与第三边框13之间的区域也设置为高隔垫物2分布区域；又例如，参见图3所示，通孔K位于靠右侧的位置，将右侧边框作为第三边框13，即， 通孔K的中心O距离第三边框13的距离h3小于通孔K的中心O距离第四边框14的距离h4，第一显示区S1还包括通孔K与第三边框13之间的区域，即，将通孔K与第三边框13之间的区域也设置为高隔垫物2分布区域。本公开实施例中，在通孔K的中心O距离第三边框13的距离小于通孔K的中心O距离第四边框14的距离时，还可以将通孔K与第三边框13之间的区域也设置为高隔垫物2分布区域，也可以加速后续形成的通孔K与第三边框13之间区域的有机封装液体流动性，有助于通孔K与第三边框13之间区域的有机封装液体的流平，改善通孔K与第三边框13之间区域的触控膜层容易被完全刻蚀掉，导致触控膜层缺失、功能失效的问题。
在一种可能的实施方式中，通孔K中心O距离第三边框13和第四边框14的距离不同时，显示区AA还包括拐角部15，参见图4或图5所示，第一边框11与第三边框13通过拐角部15衔接，第一显示区S1还包括通孔K与拐角部15之间的区域，即，将通孔K与拐角部15之间的区域也设置为高隔垫物2分布区域。本公开实施例中，将通孔K与拐角部15之间的区域也设置为高隔垫物2分布区域，也可以加速通孔K与拐角部15之间区域的有机封装液体流动性，有助于通孔K与拐角部15之间的区域的有机封装液体的流平，改善通孔K与拐角部15之间的区域的触控膜层容易被完全刻蚀掉，导致触控膜层缺失、功能失效的问题。
在具体实施时，参见图6、图7、图8和图9所示，显示区AA包括第二显示区S2和第三显示区S3，第三显示区S3设置于第二显示区S2远离通孔K的至少一侧，具体的，例如，参见图6所示，第三显示区S3设置于第二显示区S2远离通孔K的一侧，具体的，第三显示区S3设置于第二显示区S2的左侧；又例如，参见图7所示，第三显示区S3设置于第二显示区S2远离通孔K的两侧，具体的，第三显示区S3设置于第二显示区S2的左侧和右侧；又例如，参见图8所示，第三显示区S3设置于第二显示区S2远离通孔K的三侧，具体的，第三显示区S3设置于第二显示区S2的左侧、右侧和上侧；又例如，参见图9所示，第三显示区S3设置于第二显示区S2远离通孔K的四 侧，具体的，第三显示区S3设置于第二显示区S2的左侧、右侧、上侧和下侧；结合图6、图7、图8、图9所示，第二显示区S2的隔垫物2分布密度大于第三显示区S3的隔垫物2分布密度；第一显示区S1的隔垫物2的分布密度大于第二显示区S2的隔垫物2分布密度。本公开实施例中，由于外侧的显示区通常还设置有阻挡有机封装液体的挡墙结构，使第二显示区S2的隔垫物2分布密度大于第三显示区S3的隔垫物2分布密度，第一显示区S1的隔垫物2的分布密度大于第二显示区S2的隔垫物2分布密度，可以实现使通孔K与显示区的各个边框较窄区域(第一显示区S1)的有机封装液体快速流平，内部显示区(第二显示区S2)的有机封装液体流平速率次之，而对于不设置通孔且靠近边框的区域(第三显示区S3)，使有机封装液体流速较慢，避免有机封装液体在边框位置溢流。
需要说明的是，第二显示区S2和第三显示区S3为显示区AA中除第一显示区S1以外的区域，即，将第一显示区S1以外的区域进行划分，划分第二显示区S2和第三显示区S3。
在一种可能的实施方式中，参见图10所示，显示区AA具有多个子像素P，第一显示区S1内，隔垫物2位于子像素行PX内，且位于子像素行PX的相邻两个子像素P之间的间隙。本公开实施例中，将隔垫物2设置于子像素行PX内，且位于子像素行PX的相邻两个子像素P之间的间隙，可以使隔垫物2在第一显示区S1具有较大的分布密度。
具体的，第一显示区S1内，相邻两个子像素行PX的隔垫物2错位分布，例如，如图10所示，由上至下的方向上，第一个子像素行PX1内的隔垫物2的长轴延长线y1与下方的第二子像素行PX2内的隔垫物2的长轴延长线y2相互不重合。第一显示区S1内，相邻两个子像素行PX的隔垫物2错位分布，可以加速有机封装液体的流动性，促进有机封装液体的快速流动，以有助于有机封装液体的流平。
在一种可能的实施方式中，参见图11所示，第一显示区S1内，隔垫物2还设置于相邻两个子像素行PX之间的间隙处。本公开实施例中，第一显示区 S1内，隔垫物2还设置于相邻两个子像素行PX之间的间隙处，可以进一步使隔垫物2在第一显示区S1具有较大的分布密度，以促进该区域的有机封装液体的流平。
在一种可能的实施方式中，参见图12所示，第一显示区S1以外的区域，隔垫物2设置于相邻子像素行PX之间的间隙处。本公开实施例中，对于第一显示区S1内，隔垫物2设置于子像素行PX的相邻两个子像素P之间，以及设置于相邻子像素行PX之间的间隙处，而对于第一显示区S1以外的区域，隔垫物2设置于相邻子像素行PX之间的间隙处，可以实现使第一显示区S1的隔垫物2分布密度大于第一显示区S1以外的隔垫物2分布密度。
在一种可能的实施方式中，参见图13所示，第二显示区S2内，隔垫物2位于子像素行PX内，且位于相邻两个子像素P之间的间隙处；第三显示区S3内，隔垫物2位于相邻子像素行PX之间的间隙处。本公开实施例中，第二显示区S2内，隔垫物2位于子像素行PX内，且位于相邻两个子像素P之间的间隙处；第三显示区S3内，隔垫物2位于相邻子像素行PX之间的间隙处，可以实现使第一显示区S1的隔垫物2分布密度大于第二显示区S2的隔垫物2分布密度，并使第二显示区S2的隔垫物2分布密度大于第三显示区S3的隔垫物2分布密度，实现使第一显示区S1的有机封装液体快速流平，第二显示区S2的有机封装液体流平速率次之，而第三显示区S3的有机封装液体流速较慢，避免有机封装液体在边框位置溢流。
在具体实施时，结合图11所示，每一子像素行包括多个依次周期性排布的第一子像素P1、第二子像素P2、第三子像素P3，其中，第一子像素P1和第三子像素P3的形状为六边形，且在平行于子像素行PX方向(图11中的箭头AB所示方向)上，第一子像素P1的宽度h1小于第三子像素P3的宽度h3，第二子像素P2包括两个相对设置的五边形图案；下一子像素行PX的第三子像素P3与上一子像素行PX的第一子像素P1和第二子像素P2之间的间隙对应设置；相邻子像素行PX之间的隔垫物2设置于上一子像素行PX的第一子像素P1与下一子像素行PX的第三子像素P3之间的间隙Z处。本公开实施 例中，上一子像素行PX的第一子像素P1与下一子像素行PX的第三子像素P3之间的间隙Z处，具有较大的空间，将隔垫物2设置于该位置，可以降低隔垫物2的制作难度。
在具体实施时，结合图11所示，相邻子像素行PX之间的隔垫物2的长轴延线y3，与位于子像素行PX内的隔垫物2的长轴延线y4交叉。
在具体实施时，结合图11所示，第三子像素P3具有与子像素行PX垂直的第一侧边P31和第二侧边P32，分别连接于第一侧边P31两端的第三侧边P33和第四侧边P34，以及分别连接于第二侧边P32两端的第五侧边P35和第六侧边P36，其中，第二侧边P32位于第一侧边P31背离相邻第二子像素P2的一侧，第三侧边P33位于第四侧边P34的朝向上一子像素行PX的一侧；相邻子像素行PX之间的隔垫物2的长轴延线y3平行于第三侧边P33的延伸方向，位于子像素行PX内的隔垫物2的长轴延线y4垂直于子像素行PX方向。本公开实施例中，邻子像素行PX之间的隔垫物2的长轴延线y3平行于第三侧边P33的延伸方向，可以使相邻子像素行PX之间的隔垫物2具有较大的设置空间，有利于邻子像素行PX之间设置隔垫物2时，隔垫物2具有较高的制作成功率；位于子像素行PX内的隔垫物2的长轴延线y4垂直于子像素行PX方向，可以方便于不同位置的隔垫物2的设置，可以使位于子像素行PX内的隔垫物2具有较大的设置空间，有利于位于子像素行PX内设置隔垫物2时，隔垫物2具有较高的制作成功率。
在具体实施时，结合图11所示，位于子像素行PX内的隔垫物2，相邻两个隔垫物2的中心连线K1K 2穿过相邻两个隔垫物2之间的子像素的中心K 3。具体的，第二子像素P2的中心K4可以理解为两个五边形图案的构成的整体图像的中心。
在具体实施时，结合图11所示，位于相邻的第二子像素P2与第三子像素P3之间的隔垫物2的长轴延线y5与下一子像素行PX的第一子像素P1的长轴沿线y6重合。
在具体实施时，结合图11所示，相邻子像素行之间的相邻两个隔垫物2 的间距为3-8个子像素的宽度。具体的，单个子像素的宽度尺寸可以为10微米～40微米。
在一种可能的实施方式中，参见图14、图15A和图16所示，其中，图15A为图14沿虚线EF处的截面示意图，图16为图14在第一区域S1的局部放大示意图，显示面板还包括：至少一圈通孔挡墙4，通孔挡墙4与隔垫物2位于衬底基板1的相同侧，通孔挡墙4包围通孔K，通孔挡墙4包括位于通孔K最外围的第一通孔挡墙42；至少一圈边框挡墙3，边框挡墙3与通孔挡墙4位于衬底基板1的相同侧，边框挡墙3环绕显示面板的显示区AA，通孔挡墙4位于边框挡墙3包围的区域内，边框挡墙3包括与显示区AA最近的第一边框挡墙31；第一显示区S1位于第一通孔挡墙42与第一边框挡墙31之间。
在一种可能的实施方式中，参见图15A所示，第一通孔挡墙42包括背离通孔K一侧的第一侧面421，以及与第一侧面421连接的第一顶面422，第一边框挡墙31包括朝向通孔K一侧的第二侧面311，以及与第二侧面311的第二顶面312；
显示面板还包括位于第一边框挡墙31和第一通孔挡墙42之间的有机封装部52，第一侧面421在衬底基板1的正投影、第二侧面311在衬底基板1的正投影中的至少一者，与有机封装部52在衬底基板1的正投影存在交叠。本公开实施例中，第一显示区S1的高隔垫物2分布密度的设置，可以使第一显示区S1的有机封装部52较为平坦，使第一侧面421在衬底基板1的正投影、第二侧面311在衬底基板1的正投影中的至少一者，与有机封装部52在衬底基板1的正投影存在交叠，避免若有机封装部52未流平时，会在与第一边框挡墙31之间存在间隙、以及会在与第一通孔挡墙42存在间隙，使间隙位置处具有较大的膜层段差，不利于触控层的图案化制作。当然，在实际制作过程中，在制作有机封装部52的过程中，有机封装材料也可能部分外溢，即，在一种可能的实施方式中，参见图15B所示，第一顶面422在衬底基板1的正投影、第二顶面312在衬底基板1的正投影中的至少一者，与有机封装 部52在衬底基板1的正投影存在交叠。具体的，有机封装部52可以是与第一顶面在衬底基板1正投影的部分或全部交叠，有机封装部52可以是与第二顶面在衬底基板1正投影的部分或全部交叠。
在具体实施时，有机封装部52覆盖通孔挡墙4以及边框挡墙3的数量可以取决于隔垫物2的密度以及通孔挡墙4以及边框挡墙3的高度。优选实施例、结合图14以及图15A所示，通孔挡墙4可以包括两圈，边框挡墙3可以包括两圈，有机封装部52可以覆盖与其近邻一圈的通孔挡墙4与边框挡墙3的部分顶部或者全部顶部，保证流平，即，有机封装部52可以覆盖第一边框挡墙31的部分顶部或者全部顶部，有机封装部52可以覆盖第一通孔挡墙42的部分顶部或者全部顶部。
在一种可能的实施方式中，各边框挡墙3的高度可以相同。各边框挡墙3的高度可以为6微米～20微米。
在一种可能的实施方式中，结合图15A所示，显示面板还包括位于边框挡墙3背离衬底基板1一侧的第一无机封装层51，以及位于第一无机封装层51的背离衬底基板1一侧的第二无机封装层53，有机封装部52位于第一无机封装层51和第二无机封装层53之间；显示面板还包括位于衬底基板1与第一无机封装层51之间的像素界定层(图中未示出)；隔垫物2位于像素定义层的背离衬底基板1的一侧。
在一种可能的实施方式中，隔垫物2与像素定义层接触，且材质相同。
在一种可能的实施方式中，参见图17所示，衬底基板1与像素界定层之间还设置有平坦层421；通孔挡墙4由平坦层421、像素界定层422、隔垫物422(2)组合构成；通孔挡墙4与边框挡墙3同层同材质。
在一种可能的实施方式中，结合图15A所示，第二无机封装层53的背离有机封装部52的一侧还设置有图案化的触控层6。
本公开实施例还提供一种显示装置，其中，包括如本公开实施例提供的显示面板。
本公开实施例中，第一显示区S1的隔垫物2分布密度大于通孔K与第二 边框12之间的隔垫物分布密度，隔垫物2分布密度的增大，使得有更多的隔垫物2参与引流，会加速后续形成的有机封装液体的流动性，有助于第一显示区S1后续形成的有机封装液体的流平，改善若有机封装液体未流平或段差较大时，在后续形成图案化的触控层时，光刻胶涂覆不良发生，光刻胶从有机封装层较厚的区域流向有机封装层较薄的区域，导致一定区域内无光刻胶覆盖或光刻胶覆盖较薄，在进行显影刻蚀后，光刻胶缺失区域，触控膜层将被完全刻蚀掉，导致触控膜层缺失、功能失效的问题。
尽管已描述了本发明的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。
显然，本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发明实施例的精神和范围。这样，倘若本发明实施例的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
