随着手机产业的不断发展，全面屏手机的屏体由于具有较大的屏占比、窄边框的优点，能大大提高观者的视觉效果，因而受到人们的广泛关注。在全面屏的制作过程中，在屏体上通常由开槽等异形设计构成异形显示区。异形显示区的边缘通常具有弧形等不规则结构。在制作驱动基板时，由于异形显示区的边缘的弧形等不规则结构，使得驱动基板的异形非显示区的阴极和阳极搭接不均匀，这容易使得屏体的亮度不均匀，影响观感。
发明内容
基于此，有必要针对驱动基板的异形非显示区的阴极和阳极搭接不均匀的问题，提供一种驱动基板和显示面板。
一种驱动基板，包括：
基底，包括异形非显示区；
阳极层，位于所述异形非显示区，设置有用于封装的第一弧形凹槽；以及

在一个实施例中，所述第一弧形凹槽(300)具有对称中心线，所述对称中心线到任意一所述有机单元的距离大于2μm。
在一个实施例中，所述基底和所述阳极层之间设置有电路保护层，所述电路保护层设置有与所述第一弧形凹槽对应的第二弧形凹槽。
在一个实施例中，形成所述阳极层时，所述阳极层沉积于所述第二弧形凹槽的部分填充所述第二弧形凹槽。

具体实施方式
请参见图1-2，本申请实施例提供一种驱动基板10，所述驱动基板10包括基底100、阳极层200和有机单元410阵列。所述基底100包括异形非显示区110。所述阳极层200设置于所述异形非显示区110。所述阳极层200设置有用于封装的第一弧形凹槽250。所述有机单元410阵列设置于所述阳极层200。所述有机单元410阵列包括多个间隔设置的有机单元410。所述有机单元410设置于所述阳极层200远离所述基底100的表面多个所述有机单元410形成多个单元行420和多个单元列430。在每个所述单元行420和每个所述单元列430，每两个相邻的所述有机单元410之间的距离相等，所述第一弧形凹槽250位于所述有机单元阵列400中任意两个有机单元410之间。即在所述有机单元阵列400中，所述第一弧形凹槽300从任 意两个相邻设置的有机单元410之间穿过。
所述异形非显示区110可以为显示面板的拐角部分。所述拐角部分可以为弧形或者非直角的形状。所述显示面板可以设置有开槽111。所述开槽111的形状可以为圆形、椭圆形、半圆形或者其它非直线的不规则结构。所述开槽111周围的非显示区构成所述异形非显示区110。所述异形非显示区110的形状可以与所述开槽111的形状相对应。在一个实施例中，在所述开槽111的边缘为弧线形时，所述异形非显示区111的边缘也为与所述弧线形平行对应的弧形。
所述阳极层200用于与阴极层230连接。所述有机单元410可以为有机材料。所述第一弧形凹槽300用于封装。在基板封装过程中，所述第一弧形凹槽300可以增强封装效果。所述第一弧形凹槽300可以具有对称中心线，所述对称中心线可以为弧形线。所述中心对称线可以与弧形的所述异形显示区120的边缘平行。在一个实施例中，所述有机单元410由有机胶制成。所述有机单元410可以通过沉积而形成于所述阳极层200的上表面。所述有机单元410可以用来覆盖所述阳极层200开设的开口，并遮住阳极的边界，可以防止阳极中Ag的迁移。
在形成所述有机单元410阵列的过程中，所述有机单元410会落在第一弧形凹槽300的表面，因而会影响后续的封装效果。因此为了保证封装效果，需要去除落在所述第一弧形凹槽300内的有机单元410。因此所述有机单元410阵列就会被破坏。当有机单元410阵列中出现不规则的排列时，在所述有机单元410阵列上形成的阴极层230与所述阳极层200搭接就会不均匀，从而会造成屏体亮度的不均匀。尤其在去除某些有机单元410的区域，会形成较大面积的阳极。由于有机胶中的水汽无法释放，可能会带来阳极鼓泡或有机胶孔洞等问题。因此使得有机单元410阵列均匀有规则排布就显得很重要。
本申请提供的驱动基板，由于所述第一弧形凹槽300位于所述有机单元阵列430中任意两个有机单元410之间。因此所述第一弧形凹槽300不与所述有机单元410发生接触，避免了所述有机单元410落入所述第一弧形凹槽300中。在所述有机单元300不落入所述第一弧形凹槽300的基础上，每个所述单元行420中的两个相邻的所述有机单元410之间的距离相等，且每个所述单元列430中每两个相邻的所述有机单元410之间的距离相等，因此保证了所述有机单元阵列430中的多个所述有机单元410排布的均匀，即任意两个相邻的有机单元410之间的空隙大小相同。由于阴极层230形成于所述机单元阵列430远离所述基底100的表面，并通过任意两个所述有机单元410之间的空隙与所述阳极层200搭接。因此在任意相邻的两个有机单元410之间，所述阴极层230和所述阳极层200的搭接面积相同。因此也就避免了部分所述有机单元410被去除而使得所述阳极层200和所述阴极层230搭接不均匀的 问题，使得屏体显示的亮度更为均匀。
本申请实施例中，在每个所述单元行420中的两个相邻的所述有机单元410之间的距离相等，每个所述单元列430中的每两个相邻的所述有机单元410之间的距离相等。所述第一弧形凹槽300从任意两个相邻设置的有机单元410之间穿过所述有机单元410阵列。因此所述第一弧形凹槽300不与所述有机单元410发生接触，避免了所述有机单元410落入所述第一弧形凹槽300中。因此也就避免了部分所述有机单元410被去除而使得所述阳极层200和所述阴极层230的搭接不均匀的问题，使得屏体显示的亮度更为均匀。
在一个实施例中，所述有机单元410为中心对称结构。所述有机单元410可以为圆形、方形、正多边形等。中心对称结构的所述有机单元410可以随着所述第一弧形凹槽300的走势旋转，从而可以避开所述第一弧形凹槽300，并且不会改变所述有机单元410阵列的均匀性。
在一个实施例中，所述有机单元410为正方形结构。所述阳极层200开设的开口可以用来增加所述阳极层200与其它层的粘附性。所述阳极层200开设的开口可以为正方形。所述有机单元410为正方形结构可以匹配所述开口，能够节省材料。
在一个实施例中，所述正方形结构的边长为15μm-20μm。所述正方形结构的边长为15μm-20μm可以完全覆盖所述阳极层200开设的开口，又可以节省材料。
在一个实施例中，所述第一弧形凹槽300的宽度为3μm-7μm，任意相邻的两个有机单元410之间的距离为10μm-22μm。所述第一弧形凹槽300的宽度为3μm-7μm能够增强密封效果。任意相邻的两个有机单元410之间的距离为10μm-22μm可以使得任意相邻的两个有机单元4之间具有较大的距离余量，方便所述第一弧形凹槽300从所述有机单元410阵列穿过。且所述阳极层200和所述阴极层230的搭接效果好。
在一个实施例中，所述第一弧形凹槽300的对称中心线到任意一所述有机单元410的距离大于2μm。所述第一弧形凹槽300关于所述对称中心线对称。所述对称中心线到任意一所述有机单元410的距离大于2μm可以完全避免在后续封装过程中周围的有机单元410对封装的影响。
请参见图3，在一个实施例中，所述基底100和所述阳极层200之间设置有电路保护层210。所述电路保护层210设置有与所述第一弧形凹槽300对应的第二弧形凹槽310。所述电路保护层210可以为有机材料。所述电路保护层210可以设置所述第二弧形凹槽310。在所述电路保护层210远离所述基底100的表面形成所述阳极层200时，所述阳极层200沉积于所述第二弧形凹槽310的部分填充了所述第二弧形凹槽310。由于所述阳极层200在所述电路保护层210的表面形成的厚度相同，因此在所述阳极层200也形成了所述第一弧形凹槽300。 在形成所述第二弧形凹槽310后可以通过常规工序就形成所述第一弧形凹槽300，不需要增加其它工序，可以提高生产效率。
在一个实施例中，所述基底100和所述电路保护有机层之间设置有像素驱动电路层220。所述像素驱动电路层220可以包括栅极驱动电路。
在一个实施例中，所述有机单元410阵列远离所述基底100的表面设置有阴极层230。所述阴极层230通过所述有机单元410阵列与所述阳极层200搭接。所述阴极层230与所述阳极层200搭接后可以为使得电源电路层240通电。
本申请实施例还提供一种显示面板。所述显示面板包括所述的驱动基板10。所述驱动基板10还包括异形显示区120。所述异形非显示区110围绕所述异形显示区120设置。所述异形显示区120的边缘的形状可以与所述第一弧形凹槽300的形状相同。所述驱动基板10还可以包括正常显示区130。由于所述第一弧形凹槽300从任意两个相邻设置的有机单元410之间穿过所述有机单元410阵列。因此所述第一弧形凹槽300不与所述有机单元410发生接触，避免了所述有机单元410落入所述第一弧形凹槽300。因此避免了因为部分所述有机单元410被去除而使得所述阳极层200和所述阴极层230的搭接不均匀的问题，有效地改善了屏体显示亮度不均的问题，使得所述显示面板的亮度更为均匀。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为本专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
