Description

显示面板及显示终端 技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板及显示终端。
 背景技术
Stretchable Display(可伸缩显示装置)作为柔性显示继折叠技术之后的重要技术升级，具有任意方向可变形和伸缩恢复性，可以有效解决现有的四面曲、非高斯曲面贴合、显示区弯折等技术问题，具有广泛的应用前景。现有的可拉伸显示面板中，为了便于拉伸应变，显示单元呈岛屿状分散开，这些岛状单元之间通过丝带状的Hinge区域(弯折结构)相连，其中像素电路分布在岛状单元上，而像素电路彼此之间的连接线路(多条金属线)则分布于弯折结构上。
当显示面板伸缩变形时，弯折结构将受力发生形变，其中弯折结构的耐应变能力与宽度成反比。目前弯折结构常使用单层或多层钛(Ti)/铝(Al)/钛(Ti)布线，同层线路在同一层平行摆放，彼此通过水平方向预留一定距离来防止短路。如图1所示，为现有技术的岛状单元的走线简图，因弯折结构中的金属线的数量众多，例如数据线(data R/G/B)、扫描线(Scan(n-1)、Scan(n))、发光控制线(EM)、电源线(VI、VDD、VSS)等，导致弯折结构过宽，影响弯折结构的弯折性能。故，有必要改善这一缺陷。

 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。在附图中，为了清晰及便于理解和描述，附图中绘示的组件的尺寸和厚度并未按照比例。
如图2所示，为现有技术的扫描线和发光控制线的走线示意图，详细的，如图3a和图3b所示，分别为现有技术的扫描线的走线示意图和现有技术的发光控制线的走线示意图，从图3a和图3b中可以很明显的看出在一个岛状单元中有两条扫描线(Scan(n-1)和Scan(n)，或者Scan(n)和Scan(n+1))以及一条发光控制线(EM(n)或者EM(n+1))。
继续参阅图2，在弯折结构中，P1处有两条扫描线(Scan(n-1)和Scan(n))以及两条发光控制线(EM(n)和EM(n+1))，P2处有两条扫描线(Scan(n-1)和Scan(n+1))以及一条发光控制线EM(n)，P3处有两条扫描线(Scan(n)和Scan(n+1))以及一条发光控制线EM(n+1)，P4处有两条扫描线(Scan(n)和Scan(n+1))以及一条发光控制线EM(n+1)。因此，现有技术的弯折结构中均包括两条扫描线，导致弯折结构过宽，影响弯折结构的弯折性能，本申请实施例能解决上述缺陷。
如图4和图5所示，分别为本申请实施例提供的显示面板的基本结构示意图和本申请实施例提供的扫描线的走线示意图，所述显示面板包括多个岛状单元10和多个弯折结构20；多个所述岛状单元10分离设置；相邻的两个所述岛状单元10之间通过一个所述弯折结构20拉伸连接，每个所述弯折结构20包括多条金属线30，相邻的两个所述岛状单元10之间通过所述多条金属线30电性连接，所述多条金属线30仅包括一条扫描线301。
需要说明的是，本申请实施例提供的显示面板为可伸缩显示面板，其中，每一所述岛状单元10为一个显示单元，显示单元包括像素电路，像素电路的控制信号通过多条金属线30彼此连通，岛状单元10之间的弯折结构20为柔性可拉伸结构，当受到外力作用时可发生形变，使得显示面板的整体形状不固定，具有任意方向可变形和伸缩恢复性，具有广阔的应用前景。
需要说明的是，沿行方向延伸的多个弯折结构20中的多条金属线30组成一个信号线组，一个信号线组内仅包括一条扫描线301，所述一条扫描线301连续分布(如图5)。如图1至3b所示，现有技术的单个岛状单元无法同时连接两个信号线组，因此，若一个像素电路中同时需要Scan(n-1)和Scan(n)信号控制，则一个信号线组内需要设置两条扫描线(Scan(n-1)、Scan(n))，导致弯折结构过宽，影响弯折结构的弯折性能。而采用本申请实施例提供的显示面板的结构，一个信号线组内仅设置一条扫描线301，将岛状单元10分别与相邻的两个信号线组内的两条扫描线301电性连接，即可实现一个像素电路中同时受Scan(n-1)和Scan(n)信号控制，与现有的一个信号线组内需设置两条扫描线(Scan(n-1)、Scan(n))相比，减少了一条扫描线，使得弯折结构20的宽度减小，改善了弯折结构20的弯折性能。
继续参阅图4，在一种实施例中，每一所述岛状单元10分别与四个所述弯折结构20相连。具体的，每一所述岛状单元10分别通过四个所述弯折结构20与临近的四个所述岛状单元10电性连接，四个所述弯折结构20向远离所述岛状单元10的方向运动，即可放大显示面板的尺寸；四个所述弯折结构20向靠近所述岛状单元10的方向运动，即可压缩显示面板的尺寸，实现任意方向可变形和伸缩恢复性。
在一种实施例中，在与一个所述岛状单元10相连的四个所述弯折结构20中，相邻的两个所述弯折结构20中的所述扫描线301为同一条所述扫描线301的一部分。
可以理解的是，如图5所示，沿同一行的方向延伸的多个弯折结构20中的扫描线301均为同一条扫描线，岛状单元10通过分别与其上、下的两条扫描线301相连，从而实现既可获取Scan(n-1)信号，又可获取Scan(n)信号，而且一个弯折结构20中仅需设置一条扫描线301，与现有的一个弯折结构中需设置两条扫描线相比，减少了一条扫描线，使得弯折结构20的宽度减小，改善了弯折结构20的弯折性能。
继续参阅图4，在一种实施例中，每一所述岛状单元10包括第一凸起部101和第二凸起部102，所述第一凸起部101和所述第二凸起部102相对设置；在与一个所述岛状单元10相连的四个所述弯折结构20中，相邻的两个所述弯折结构20与同一所述第一凸起部101或同一所述第二凸起部102相连。
可以理解的是，本申请实施例通过在岛状单元10的两端分别设置第一凸起部101和第二凸起部102，可以增大两个信号线组之间的间距，即增大了四个岛状单元10以及四个弯折结构20围成的空白区域(即挖空区域)的面积，增大了显示面板的可伸缩范围，使得显示面板的形变更加多样化。
在一种实施例中，在所述第一凸起部101至所述第二凸起部102的方向上，所述第一凸起部101和所述第二凸起部102的高度均大于或等于1微米且小于或等于100微米。需要说明的是，所述第一凸起部101和所述第二凸起部102的高度根据显示面板的分辨率来决定，当需要增大显示面板的分辨率，可以通过缩小所述第一凸起部101和所述第二凸起部102的高度来达成。
在一种实施例中，在所述第一凸起部101至所述第二凸起部102的方向上，所述第一凸起部101的高度与所述第二凸起部102的高度相等。可以理解的是，本申请实施例通过将所述第一凸起部101的高度设置为与所述第二凸起部102的高度相等，使得岛状单元10分布更加均匀，使得弯折结构20受力更加均匀，不容易发生断裂。
在一种实施例中，所述多条金属线30还包括发光控制线302(如图6)、初始化电源线303(如图7)、驱动电源线304(如图8)以及公共电源线305(如图9)。接下来，请参阅图6，为本申请实施例提供的发光控制线的走线示意图，其中，每一所述岛状单元10与相邻的一条所述发光控制线302电性连接。需要说明的是，发光控制线302主要用于像素电路的发光阶段，当处于发光阶段时，给发光控制线302一个低电平，使得显示单元发光，从而形成相应的图像。发光控制线302的走线与扫描线301的走线类似，沿行方向连续分布，不通过岛状单元10进行上下连通。与现有技术的弯折结构的P1处的两条发光控制线相比，减少了一条发光控制线，减小了弯折结构20的宽度，改善了弯折结构20的弯折性能。
接下来，请参阅图7，为本申请实施例提供的初始化电源线的走线示意图，相邻的两条所述初始化电源线303通过位于所述相邻的两条所述初始化电源线303之间的所述岛状单元10电性连接。即相邻的两条初始化电源线303通过多个岛状单元10相连通，形成mesh(网状)结构，可以降低IR drop(电压降)，提升显示面板的显示均匀性。
接下来，请参阅图8，为本申请实施例提供的驱动电源线的走线示意图，相邻的两条所述驱动电源线304通过位于所述相邻的两条所述驱动电源线304之间的所述岛状单元10电性连接。即相邻的两条驱动电源线304通过多个岛状单元10相连通，形成mesh(网状)结构，可以降低IR drop(电压降)，提升显示面板的显示均匀性。
接下来，请参阅图9，为本申请实施例提供的公共电源线的走线示意图，相邻的两条所述公共电源线305通过位于所述相邻的两条所述公共电源线305之间的所述岛状单元10电性连接。即相邻的两条公共电源线305通过多个岛状单元10相连通，形成mesh(网状)结构，可以降低IR drop(电压降)，提升显示面板的显示均匀性。
接下来，请参阅图10，为本申请实施例提供的数据线的走线示意图，其中，所述显示面板还包括多条第一数据线306和多条第二数据线307；每个所述岛状单元10内均有一条所述第一数据线306和一条所述第二数据线307穿过；穿过一个所述岛状单元10的所述第一数据线306的第一端通过一所述弯折结构20与穿过相邻的一所述岛状单元10的所述第二数据线307的第二端电性连接，穿过一个所述岛状单元10的所述第一数据线306的第二端通过另一所述弯折结构20与穿过相邻的另一所述岛状单元10的所述第二数据线307的第一端电性连接；穿过一个所述岛状单元10的所述第二数据线307的第一端通过一所述弯折结构20与穿过相邻的一所述岛状单元10的所述第一数据线306的第二端电性连接，穿过一个所述岛状单元10的所述第二数据线307的第二端通过另一所述弯折结构20与穿过相邻的另一所述岛状单元10的所述第一数据线306的第一端电性连接。
可以理解的是，第一数据线306和第二数据线307均穿过岛状单元10和弯折结构20上下连通，本申请实施例提供的显示面板的每一弯折结构20内均只有一条数据线(第一数据线306或第二数据线307)经过，与图1的现有技术的一个弯折结构对应三条数据线(data R/G/B)相比，减少了两条数据线，也可以使得弯折结构20的宽度减小，改善弯折结构20的弯折性能。
接下来，请参阅图11a，为本申请实施例提供的岛状单元的第一种排布示意图，其中，每一所述岛状单元10为一个显示单元，多个所述显示单元包括多个第一显示单元11、多个第二显示单元12以及多个第三显示单元13；所述第一显示单元11的子像素为红色子像素和绿色子像素(RG)，所述第二显示单元12的子像素为绿色子像素和蓝色子像素(GB)，所述第三显示单元13的子像素为蓝色子像素和红色子像素(BR)。其中，与所述第一显示单元11相邻的四个所述岛状单元10分别为两个所述第二显示单元12和两个所述第三显示单元13，两个所述第二显示单元12位于所述第一显示单元11的一侧，两个所述第三显示单元13位于所述第一显示单元11的另一侧。
需要说明的是，图11a中以第一显示单元11为红色子像素和绿色子像素(RG)、第二显示单元12为绿色子像素和蓝色子像素(GB)、第三显示单元13为蓝色子像素和红色子像素(BR)为例进行绘示，其中，与所述第一显示单元11(RG)相邻的四个所述岛状单元10分别为两个所述第二显示单元12(GB)和两个所述第三显示单元13(BR)，两个所述第二显示单元12(GB)位于所述第一显示单元11(RG)的一侧(右侧)，两个所述第三显示单元13(BR)位于所述第一显示单元11(RG)的另一侧(左侧)。其他实施方式此处不再赘述。

需要说明的是，图11b中以第一显示单元11为红色子像素和绿色子像素(RG)、第二显示单元12为绿色子像素和蓝色子像素(GB)为例进行绘示，其中，与所述第一显示单元11(RG)相邻的四个所述岛状单元10均为所述第二显示单元12(GB)。其他实施方式此处不再赘述。
需要说明的是，图11a中一条数据线仅传输R信号，或仅传输G信号，或仅传输B信号。图11b中一条数据线仅传输G信号，或既传输R信号又传输B信号(可以通过定制驱动芯片来实现不同行打开，传输不同的数据信号R或B)。
接下来，请参阅图12a~图12d，在一种实施例中，所述显示面板还包括衬底层401、第一金属层41、第二金属层42以及第三金属层43；所述第一金属层41位于所述衬底层401上，所述第一金属层41图案化形成所述扫描线301、所述发光控制线302、所述第一数据线306以及所述第二数据线307；所述第二金属层42位于所述第一金属层41上，所述第二金属层42图案化形成所述驱动电源线304和所述公共电源线305；所述第三金属层43位于所述第二金属层42上，所述第三金属层43图案化形成所述初始化电源线303；其中，所述第三金属层43、所述第二金属层42、所述第一数据线306以及所述第二数据线307在所述衬底层401上的正投影均不重叠。
具体的，图12a、图12b、图12c以及图12d分别为图4中的显示面板沿A-A’方向的剖面图、沿B-B’方向的剖面图、沿C-C’方向的剖面图以及沿D-D’方向的剖面图，其中，沿A-A’方向的剖面图的弯折结构中包括一条扫描线3011(即Scan(n-1))、一条发光控制线302，与现有技术的弯折结构中P1处相比，减少了一条扫描线和一条发光控制线；沿B-B’方向的剖面图的弯折结构中包括一条扫描线3011(即Scan(n-1))、一条发光控制线302，与现有技术的弯折结构中P2处相比，减少了一条扫描线；沿C-C’方向的剖面图的弯折结构中包括一条扫描线3011(即Scan(n-1))、一条发光控制线302，与现有技术的弯折结构中P3处相比，减少了一条扫描线；沿D-D’方向的剖面图的弯折结构中包括一条扫描线3012(即Scan(n))、一条发光控制线302，与现有技术的弯折结构中P4处相比，减少了一条扫描线。因此，采用本申请实施例提供的显示面板，可以减少弯折结构中的扫描线，使得弯折结构的宽度减小，改善了弯折结构的弯折性能。
可以理解的是，本实施例通过将第三金属层43、第二金属层42、第一数据线306以及第二数据线307在衬底层401上的正投影设置为均不重叠，可以避免初始化电源线303、驱动电源线304、公共电源线305、第一数据线306以及第二数据线307之间产生寄生电容，避免对像素电路造成影响。
需要说明的是，第一金属层41和第二金属层42之间还设置有第一平坦化层402，第二金属层42和第三金属层43之间还设置有第二平坦化层403，第三金属层43远离第二平坦化层403的一侧还设置有第三平坦化层404。其中，第一平坦化层402、第二平坦化层403以及第三平坦化层404用于将第一金属层41、第二金属层42以及第三金属层43隔开，以及填平第一金属层41、第二金属层42以及第三金属层43上的段差。
本申请实施例还提供一种显示终端，包括终端主体和上述的显示面板，所述终端主体与所述显示面板组合为一体，所述显示面板的结构请参阅图4至图12d及相关说明，此处不再赘述。本申请实施例提供的显示终端可以为：手机、平板电脑、笔记本电脑、电视机、数码相机、导航仪等具有显示功能的产品或部件。
综上所述，本申请实施例提供的一种显示面板，包括多个岛状单元和多个弯折结构；多个岛状单元分离设置；相邻的两个岛状单元之间通过弯折结构拉伸连接，弯折结构包括多条金属线，相邻的两个岛状单元之间通过多条金属线电性连接，多条金属线仅包括一条扫描线；本申请通过在一个弯折结构中仅设置一条扫描线，与现有的一个弯折结构中需设置两条扫描线(Scan(n-1)、Scan(n))相比，减少了一条扫描线，使得弯折结构的宽度减小，改善了弯折结构的弯折性能，解决了现有技术的显示面板的弯折结构中的金属线的数量众多，导致弯折结构过宽，影响弯折结构的弯折性能的技术问题。
以上对本申请实施例所提供的一种显示面板及显示终端进行了详细介绍。应理解，本文所述的示例性实施方式应仅被认为是描述性的，用于帮助理解本申请的方法及其核心思想，而并不用于限制本申请。
