具体实施方式
为使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。
通常，可通过降低显示基板的四个角落区域的像素密度(PPI)，并在这四个角落区域设置带有开口图案的可拉伸结构，从而可将显示基板的边缘或角落按照一定弯曲半径进行弯曲，从而实现四曲面屏设计。此时，位于四个角落区域的可拉伸结构的拉伸量越大，则这四个角落区域的像素密度越低，即为低像素密度区。另一方面，由于这四个角落区域设置有开口图案，这些开口图案将像素阵列分割为孤立的多个像素岛；而这些像素岛中的像素的驱动线(例如栅线、数据线等)均需要相互连接，但是这些驱动线无法直接跨过这些开口图案，因此像素单元的控制线和数据线需要绕开开口图案进行布线。
对此，本公开实施例提供一种显示基板和显示装置。该显示基板包括：多个像素岛、第一开口、第二开口和第一通道区；多个像素岛沿第一方向和第二 方向阵列设置；第一开口位于在第二方向上相邻的两个像素岛之间；第二开口位于在第一方向上相邻的两个像素岛之间；第一通道区至少部分位于第一开口和第二开口之间并将在第一方向上相邻的两个像素岛相连；各像素岛在第一方向上与第一开口交叠，各像素岛包括至少一个像素，各像素包括沿第一方向延伸的多条第一驱动线，第一通道区设置有多条第一连接线，各像素岛还包括沿第二方向延伸的多条转接线，多条转接线与多条第一驱动线异层设置，且相互交叉以形成多个交叠区；多条转接线通过位于部分交叠区的过孔与多条第一驱动线电性相连，在第一方向上相邻的两个像素岛中的多条转接线分别与第一通道区中的多条第一连接线相连。该显示基板通过多条转接线将各像素岛中的多条第一驱动线引出，并通过第一通道区中多条第一连接线将在第一方向上相邻的两个像素岛的多条第一驱动线分别相连，从而实现将在第一方向上相邻的两个像素岛中的多条第一驱动线相连。由此，该显示基板可实现在具有开口图案的可拉伸区或者弯折区实现驱动线的布线。
下面，结合附图对本公开实施例提供的显示基板和显示装置进行详细的说明。
本公开一实施例提供一种显示基板。图1为本公开一实施例提供的一种显示基板的平面示意图。如图1所示，该显示基板100包括多个像素岛110、第一开口121、第二开口122和第一通道区130；多个像素岛110沿第一方向和第二方向阵列设置。像素岛110之间的距离较大，例如，相邻像素岛110之间的距离大于像素岛110中相邻像素140之间的距离。第一开口121位于在第二方向上相邻的两个像素岛110之间；第二开口122位于在第一方向上相邻的两个像素岛110之间；第一通道区130至少部分位于第一开口121和第二开口122之间并将在第一方向上相邻的两个像素岛110相连；各像素岛110在第一方向上与第一开口121交叠，也就是说，像素岛在沿第一方向延伸的一条参考直线上的正投影与第一开口在该参考直线上的正投影相互交叠。
各像素岛110包括至少一个像素140，各像素140包括沿第一方向延伸的多条第一驱动线142，第一通道区130设置有多条第一连接线132，各像素岛110还包括沿第二方向延伸的多条转接线112，多条转接线112与多条第一驱动线142异层设置，且相互交叉以形成多个交叠区150；多条转接线112通过位于部分交叠区150的过孔152与多条第一驱动线142电性相连，在第一方向上相邻的两个像素岛110中的多条转接线112分别与第一通道区130中的多条 第一连接线132相连。需要说明的是，在显示基板中，第一驱动线可为栅线，位于第一栅极层和第二栅极层中的一层；此时，上述的转接线可位于其他导电层，例如第一栅极层和第二栅极层中的另一层、第一源漏金属层、第二源漏金属层、或者遮光层。另外，上述的过孔根据其所连接的第一驱动线和转接线的不同而具有不同的深度，并且相邻的过孔错位设置，避免相互干扰。在本公开实施例提供的显示基板中，在各像素岛110中，各像素140的多条第一驱动线142可通过转接线112引出，然后在第一方向上相邻的两个像素岛110中的多条转接线112分别与第一通道区130中的多条第一连接线132相连，从而实现将在第一方向上相邻的两个像素岛110中的多条第一驱动线142相连。由此，该显示基板可实现在具有开口图案的可拉伸区或者弯折区实现驱动线的布线。并且，该显示基板通过充分利用第一开口和第二开口之间的第一通道区，从而可保证第一开口和第二开口具有较大的尺寸，从而也可提高该显示基板的拉伸或弯曲性能。
在一些示例中，如图1所示，各像素岛110包括两个子区域114和位于两个子区域114之间的转接区116，像素岛110包括的至少一个像素140设置在两个子区域114中，转接线112位于转接区116。由此，该显示基板通过在像素岛110中设置转接区116来放置上述的转接线112，并且将转接区116设置在两个子区域114之间，从可提高像素140在像素岛110中的分布对称性。
在一些示例中，如图1所示，多条第一驱动线142穿过两个子区域114和转接区116，多条第一驱动线142被配置为驱动两个子区域114中的像素140以进行发光显示。需要说明的是，两个子区域中的一个可以是虚设区域(dummy)，即不进行显示的区域。
例如，上述的第一驱动线142可包括栅线、发射控制线、初始化线等沿第一方向延伸的驱动线。
在一些示例中，如图1所示，第一开口121沿所述第一方向延伸，第二开口122沿第二方向延伸，第一开口121和第二开口122在第一方向上交替排列，第一开口121和第二开口122在第二方向上也交替排列。由此，在第一开口和第二开口所在的区域，该显示基板可更好地进行弯曲或者折叠，便于形成实现四曲面屏设计。
在一些示例中，如图1所示，第一通道区130位于像素岛110与第一开口121之间，且位于第一开口121与第二开口122靠近第一开口121的端部之间。 由此，第一通道区130可绕开第一开口121和第二开口122，并实现高效利用显示基板上的空间。
在一些示例中，如图1所示，第一开口121在第一方向上与相邻的两个像素岛110均交叠。由此，第一开口的分布面积较大，从而利于显示基板进行弯曲。
在一些示例中，如图1所示，第二开口122在第一开口121上的正投影位于第一开口121的中间。由此，该显示基板的第二开口和第一开口的分布具有较高的对称性，从而可灵活地进行弯曲。
在一些示例中，如图1所示，各像素140包括多个子像素160，各子像素160包括像素驱动电路162和像素驱动电路162电性相连的阳极164。
图2为本公开一实施例提供的一种显示基板中像素的平面示意图。图3为本公开一实施例提供的一种显示基板沿图2中AA方向的剖面示意图。如图2和图3所示，该显示基板100包括：衬底基板101、半导体层102、栅极绝缘层103、第一栅极层104、层间绝缘层105、第二栅极层106、钝化层107和第一导电层108；半导体层102位于衬底基板101上；栅极绝缘层103位于半导体层102远离衬底基板101的一侧；第一栅极层104位于栅极绝缘层103远离半导体层102的一侧；层间绝缘层105位于第一栅极层104远离栅极绝缘层103的一侧；第二栅极层106位于层间绝缘层105远离第一栅极层104的一侧；钝化层107位于第二栅极层106远离层间绝缘层105的一侧；第一导电层108位于钝化层104远离第二栅极层106的一侧。上述的多条第一驱动线142位于第一栅极层104和第二栅极层106中的至少之一，上述的转接线112位于第一导电层108。由此，通过将上述的转接线112设置在第一导电层108，一方面可利用该显示基板中既有的导电层，另一方面可与第一驱动线异层设置，方便形成上述的交叠区150，从可灵活地进行连线。
在一些示例中，如图2和图3所示，该显示基板100还包括绝缘层109和第二导电层1010；绝缘层109位于第一导电层108远离钝化层107的一侧；第二导电层1010位于绝缘层109远离第一导电层108的一侧。第二导电层1010包括位于像素岛110的导电网格118，导电网格118与像素岛110中的多条电源线均电性相连。

如图4A和图5所示，第三源极区223S、第一漏极区221D和第五源极区225S连接至第一节点N1，第六漏极区226D和第三漏极区223D相连，第一源极区221S、第二漏极区222D和第四漏极区224D连接至第二节点N2，第五漏极区225D和第七漏极区227D相连；第二电极块261在衬底基板101上的正投影与第一电极块241在衬底基板101上的正投影至少部分重叠以形成存储电容Cst。
如图4B、图4C和图5所示，多条第一驱动线142包括：初始化信号线1421，位于第二栅极层106；复位信号线1422，位于第一栅极层104；栅线1423，位于第一栅极层104；以及发光控制线1424，位于第一栅极层104；初始化信号线1421与第七源极区227S和第六源极区226S相连，复位信号线1422与第七沟道区227C和第六沟道区226C交叠，以与第七半导体单元227和第六半导体单元226形成第七薄膜晶体管T7和第六薄膜晶体管T6，栅线1423分别与第三沟道区223C和第二沟道区222C交叠，以与第三半导体单元223和第二半导体单元222形成第三薄膜晶体管T3和第二薄膜晶体管T2，第一电极块241与第一沟道区221C交叠，以与第一半导体单元221形成第一薄膜晶体管T1，发光控制线1424与第四沟道区224C和第五沟道区225C交叠，以与第四 半导体单元224和第五半导体单元225形成第四薄膜晶体管T4和第五薄膜晶体管T5。
如图4D和图5所示，该显示基板100还包括多条第二驱动线148；多条第二驱动线148包括：多条电源线1481，位于第一导电层108，各电源线1481且与像素驱动电路162中的第四源极区224S相连；以及多条数据线1482，位于第一导电层108，各数据线1482与像素驱动电路162中的第二源极区222S相连。
在一些示例中，如图1所示，多条转接线112的数量小于多条第一驱动线142的数量。从而可减小转接线112的数量，从而降低多条转接线112所占据的面积，提高像素密度。
在一些示例中，如图1所示，各像素岛110包括沿第二方向排列的至少两个像素140，多条第一驱动线142中的至少两条与同一条转接线112相连。由此，可减小转接线112的数量，从而降低多条转接线112所占据的面积，提高像素密度，并且可进一步保证第一开口和第二开口具有较大的尺寸，从而可进一步提高该显示基板的拉伸或弯曲性能。
在一些示例中，如图1所示，各像素岛110包括呈矩阵排列的四个像素140，各像素岛110包括第一子区域114A、第二子区域114B和位于第一子区域114A和第二子区域114B之间的转接区116，第一子区域114A包括沿第二方向排列的第一像素1401和第二像素1402，第二子区域114B包括沿第二方向排列的第三像素1403和第四像素1404。第一像素1401的初始化信号线1421和第三像素1403的初始化信号线1421为第一初始化信号线1421A，第二像素1402的初始化信号线1421和第四像素1404的初始化信号线1421为第二初始化信号线1421B；多条转接线112包括第一转接线1121，第一像素1401和第三像素1403的第一初始化信号线1421A通过过孔152与第一转接线1121电性相连，第二像素1402和第四像素1404的第二初始化信号线1421B通过过孔152与第一转接线1121相连。由此，该显示基板可仅通过一条转接线就可将四个像素的初始化信号线引出，从而可降低转接线的数量，以降低多条转接线所占据的面积，提高像素密度。
在一些示例中，如图1所示，第一像素1401的复位信号线1422和第三像素1403的复位信号线1422为第一复位信号线1422A，第二像素1402的复位信号线1422和第四像素1404的复位信号线1422为第二复位信号线1422B； 多条转接线112包括第二转接线1122和第三转接线1123，第一像素1401和第三像素1403的第一复位信号线1422A通过过孔152与第二转接线1122电性相连，第二像素1402和第四像素1404的第二复位信号线1422B通过过孔与第三转接线1123相连。由此，该显示基板可仅通过两条转接线就可将四个像素的复位信号线引出，从而可进一步降低转接线的数量，以降低多条转接线所占据的面积，提高像素密度。
在一些示例中，如图1所示，第一像素1401的栅线1423和第三像素1403的栅线1423为第一栅线1423A，第二像素1402的栅线1423和第四像素1404的栅线1423为第二栅线1423B；多条转接线112包括第四转接线1124，第一像素1401和第三像素1403的第一栅线1423A通过过孔152与第三转接线1123电性相连，第二像素1402和第四像素1404的第二栅线1423B通过过孔152与第四转接线1124相连。由此，该显示基板可仅通过增加一条转接线就可将四个像素的栅线引出，从而可进一步降低转接线的数量，以降低多条转接线所占据的面积，提高像素密度。
在一些示例中，如图1所示，第一像素1401的发光控制线1424和第三像素1403的发光控制线1424为第一发光控制线1424A，第二像素1402的发光控制线1424和第四像素1404的发光控制线1424为第二发光控制线1424B；多条转接线112包括第五转接线1125和第六转接线1126，第一像素1401和第三像素1403的第一发光控制线1424A通过过孔152与第五转接线1125电性相连，第二像素1402和第四像素1404的第二发光控制线1424B通过过孔152与第六转接线1126相连。由此，该显示基板可仅通过增加二条转接线就可将四个像素的发光控制线引出，从而可进一步降低转接线的数量，以降低多条转接线所占据的面积，提高像素密度。
图6为本公开一实施例提供的另一种显示基板的平面示意图。如图6所示，第一像素1401的发光控制线1424和第三像素1403的发光控制线1424为第一发光控制线1424A，第二像素1402的发光控制线1424和第四像素1404的发光控制线1424为第二发光控制线1424B；多条转接线112包括第五转接线1125，第一像素1401和第三像素1403的第一发光控制线1424A通过过孔152与第五转接线1125电性相连，第二像素1402和第四像素1404的第二发光控制线1424B通过过孔152与第五转接线1125相连。由此，该显示基板可仅通过增加一条转接线就可将四个像素的发光控制线引出，从而可进一步降低转接 线的数量，以降低多条转接线所占据的面积，提高像素密度。
值得注意的是，图1和图6所示的实施例仅示出了一个像素岛110包括矩阵排列的四个像素140的情况，但本公开实施例包括但不限于此，该显示基板可通过一条转接线将信号相同或者信号可分时的不同第一驱动线相连，从而减小转接线的数量。
在一些示例中，如图1所示，多条第一连接线132设置在第一栅极层104和第二栅极层106。例如，多条第一连接线132交替设置在第一栅极层104和第二栅极层106。此时，相邻的第一连接线132在衬底基板101上的正投影之间的距离可设置得较小，也就是说，多条第一连接线可设置得更密集，从而可降低第一通道区的宽度或者增加第一通道区中第一连接线的数量。
在一些示例中，如图1所示，多条转接线112的数量与多条第一连接线132的数量相同，多条转接线112与多条第一连接线132一一对应设置。由此，该显示基板可通过第一连接线将在第一方向上相邻的两个像素岛中的转接线相连，从而实现将在第一方向上相邻的两个像素岛中的多条第一驱动线相连。
图7为本公开一实施例提供的一种显示基板的平面示意图。如图7所示，该显示基板100还包括：第二通道区170，位于第一开口121和第二开口122之间并将在第二方向上相邻的两个像素岛110相连。各像素岛110包括沿第二方向延伸的多条第二驱动线148，第二通道区170设置有多条第二连接线172，多条第二连接线172分别将在第二方向上相邻的两个像素岛110的多条第二驱动线148相连。
在一些示例中，如图2、图3和图7所示，多条第二驱动线148包括：多条电源线1481，位于第一导电层108，各电源线1481且与像素驱动电路162中的第四源极区224S相连；以及多条数据线1482，位于第一导电层108，各数据线1482与像素驱动电路162中的第二源极区222S相连。
在一些示例中，如图2、图3和图7所示，该显示基板100还包括绝缘层109和第二导电层1010；绝缘层109位于第一导电层108远离钝化层107的一侧；第二导电层1010位于绝缘层109远离第一导电层108的一侧。第二导电层1010包括位于像素岛110的导电网格118，导电网格118与像素岛110中的多条电源线1481均电性相连。
此时，如图7所示，多条第二连接线172包括电源连接线1721，位于第二导电层1010，且与导电网格118相连。由于导电网格118与像素岛110中的多 条电源线1481均电性相连，因此在第二方向上相邻的两个像素岛110可仅通过一条第二连接线172就可将在第二方向上相邻的两个像素岛110中所有像素140的电源线1481相连。
图8为本公开一实施例提供的一种显示基板中第二导电层的示意图。如图8所示，电源连接线1721位于第二导电层1010，且与导电网格118相连。由于导电网格118与像素岛110中的多条电源线1481均电性相连，因此在第二方向上相邻的两个像素岛110可仅通过一条第二连接线172就可将在第二方向上相邻的两个像素岛110中所有像素140的电源线1481相连。
在一些示例中，如图7所示，多条第二连接线172还包括多条数据连接线1722，多条数据连接线1722与多条数据线1482一一对应设置并连接。由此，该显示基板可通过多条数据连接线将在第二方向上相邻的两个像素岛110中所有像素140的数据线1482相连。
在一些示例中，如图7所示，多条第二连接线172设置在第一导电层108和第二导电层1010；例如，多条第二连接线172交替设置在第一导电层108和第二导电层1010。此时，相邻的第二连接线172在衬底基板101上的正投影之间的距离可设置得较小，也就是说，多条第二连接线可设置得更密集，从而可降低第二通道区的宽度或者增加第二通道区中第二连接线的数量。
在一些示例中，如图7所示，各像素140包括第一颜色子像素1601、第二颜色子像素1602和第三颜色子像素1603，各像素岛110包括呈矩阵排列的四个像素140，各像素岛140包括第一子区域144A、第二子区域144B和位于第一子区域144A和第二子区域144B之间的转接区146；第一子区域144A包括沿第二方向排列的第一像素1401和第二像素1402，第二子区域144B包括沿所述第二方向排列的第三像素1403和第四像素1404；第一像素1401中的第一颜色子像素1601的数据线1482和第二像素1402中的第一颜色子像素1601的数据线1482为第一数据线1482A，第一像素1401中的第二颜色子像素1602的数据线1482和第二像素1402中的第二颜色子像素1602的数据线1482为第二数据线1482B，第一像素1401中的第三颜色子像素1603的数据线1482和第二像素1402中的第三颜色子像素1603的数据线1482为第三数据线1482C，第三像素1403中的第一颜色子像素1601的数据线1482和第四像素1404中的第一颜色子像素1601的数据线1482为第四数据线1482D，第三像素1403中的第二颜色子像素1602的数据线1482和第四像素1404中的第二颜色子像素 1602的数据线1482为第五数据线1482E，第三像素1403中的第三颜色子像素1603的数据线1482和第四像素1404中的第三颜色子像素1603的数据线1482为第六数据线1482F。需要说明的是，为了清楚，图7中没有示出144A、144B、146、1401、1402、1403和1404；第一子区域144A、第二子区域144B、转接区146、第一像素1401、第二像素1402、第三像素1403和第四像素1404的划分可参见图1。
如图7和图8所示，多条第二连接线172包括第一数据连接线1722A、第二数据连接线1722B、第三数据连接线1722C、第四数据连接线1722D、第五数据连接线1722E和第六数据连接线1722F；第一数据连接线1722A与第一数据线1482A相连，第二数据连接线1722B与第二数据线1482B相连，第三数据连接线1722C与第三数据线1482C相连，第四数据连接线1722D与第四数据线1482D相连，第五数据连接线1722E与第五数据线1284E相连，第六数据连接线1722F与第六数据线1482D相连。由此，该显示基板可通过同一数据连接线将在第二方向上相邻两个像素岛中位于同一列的子像素的数据线相连。
在一些示例中，如图7和图8所示，第一数据连接线1722A、第二数据连接线1722B、第五数据连接线1722E位于第一导电层108；电源连接线1721、第三数据连接线1722C、第四数据连接线1722D和第六数据连接线1722F位于第二导电层1010。由此，第一数据连接线1722A、第二数据连接线1722B、第三数据连接线1722C、第四数据连接线1722D、第五数据连接线1722E、第六数据连接线1722F和电源连接线1721在衬底基板101上的正投影之间的距离可设置得较小，也就是说，这些第二连接线可设置得更密集，从而可降低第二通道区的宽度或者增加第二通道区中第二连接线的数量。
图9为本公开一实施例提供的一种显示基板的平面示意图。如图9所示，显示基板100包括第一显示区域181和第二显示区域182，第一显示区域181的像素密度大于第二显示区域182的像素密度，像素岛110位于第二显示区域182。
值得注意的是，由于第一显示区域181的像素密度大于第二显示区域182的像素密度，第一显示区域181中存在较多的像素，这些像素可通过第三连接线与对应的驱动电路相连。此时，第三连接线也可通过上述的第一通道区、第二通道区和转接区进行走线。
在一些示例中，该显示基板100还包括位于第一显示区域181和第二显示 区域182之间的过渡区域183，过渡区域183的像素密度小于第一显示区域181的像素密度，但是过渡区域183的像素密度可大于等于第二显示区域182的像素密度。过渡区域183不设置上述的开口，并且可设置用于驱动该显示基板100的像素进行发光显示的行驱动电路。在一些示例中，如图9所示，第二显示区域182位于第一显示区域181的角落。例如，该显示基板100的平面形状大致为圆角矩形，第二显示区域182位于在该显示基板100的四个角落区域，即上述的第二显示区域182可进行弯曲，从而可实现四曲面屏设计。
在一些示例中，如图9所示，第一显示区域181的平面形状包括第一矩形和位于第一矩形在所述第二方向上的两侧的两个第二矩形，所述第二显示区域的平面形状包括四个扇形，分别位于所述两个第二矩形沿所述第一方向上的两侧。
在一些示例中，第二显示区域182的显示基板100在垂直于第一显示区域181的方向上可弯曲。例如，该显示基板100包括出光侧，即显示基板100发出的光线出射的一侧，显示基板100位于第二显示区域182的部分可向与该出光侧相反的一侧进行弯曲，从而实现一种曲面形态的3D立体效果，由此可营造显示立体沉浸感。
本公开一实施例还提供一种显示装置。图10为本公开一实施例提供的一种显示装置的示意图。如图10所示，该显示装置900包括上述的显示基板100。由于该显示基板100可实现在具有开口图案的可拉伸区或者弯折区实现驱动线的布线，因此包括该显示基板100的显示装置900也可实现在具有开口图案的可拉伸区或者弯折区实现驱动线的布线，从而在具有较窄的边框宽度的同时，实现四曲面屏设计。
例如，上述的显示装置可为电视、手机、电脑、导航仪、电子画框等具有显示功能的电子产品。
有以下几点需要说明：
(1)本公开实施例附图中，只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计。
(2)在不冲突的情况下，本公开同一实施例及不同实施例中的特征可以相互组合。
以上，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化 或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
