一种柔性显示屏、显示终端
本申请要求于2019年10月28日提交国家知识产权局、申请号为201911030645.9、申请名称为“一种柔性显示屏、显示终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种柔性显示屏、显示终端。
背景技术
有机发光二极管(Organic Light Emitting Diode，OLED)作为一种电流型发光器件，因其所具有的自发光、快速响应、宽视角等特点而越来越多地被应用于高性能显示领域当中。柔性显示屏中，当用于承载OLED发光器件的衬底为柔性衬底时，上述柔性显示屏可以为柔性显示屏，从而能够实现显示屏的弯折。
目前，在显示屏的制作过程中，可以将柔性显示屏的非发光区的一部分弯折至显示屏背面，以减小显示屏的边框，使得显示屏能够获得更大的屏占比。然而，当用户在使用柔性显示屏时，在对柔性显示屏进行弯折时，原本被弯折至显示屏背面的那部分非发光区会再一次受到弯折，从而在此处容易产生应力集中，出现积压褶皱而导致屏幕出现折叠失效等问题。
发明内容
本申请实施例提供一种柔性显示屏、显示终端，用于减小显示屏的非发光区多重折叠导致应力集中的问题出现的几率。
为达到上述目的，本申请采用如下技术方案：
本申请实施例的第一方面，提供一种显示终端。该显示终端包括支撑组件和柔性显示屏。其中，支撑组件包括第一壳体、第二壳体以及转轴。转轴位于第一壳体和第二壳体之间。第一壳体和第二壳体通过转轴转动连接。柔性显示屏的背面与第一壳体、第二壳体以及转轴相连接。柔性显示屏中与转轴相连接的部分作为第一弯折部。第一弯折部用于沿转轴轴线的方向弯折，将柔性显示屏中分别与第一壳体和第二壳体相连接的部分对折。柔性显示屏具有发光区以及设置于发光区周边的非发光区。此外，柔性显示屏包括第一周边部和第二周边部。第一周边部和第二周边部在非发光区内，并排设置于发光区的同一侧。第一周边部弯折至柔性显示屏背面的部分朝向第一壳体。第二周边部弯折至柔性显示屏背面的部分朝向第二壳体。第一缺口在非发光区内，设置于第一弯折部的一侧，且位于第一周边部和第二周边部之间。这样一来，通过设置上述第一缺口，可以将柔性显示屏的非发光区中用于与驱动芯片相耦接的部分，进行分段形成多个上述周边部，例如，第一周边部和第二周边部。通过对每个周边部单独进行弯折，可以减少非发光区弯折部分的长度，提高弯折的良率。此外，由于第一缺口位于第一弯折部的一侧，且设置于第一周边部和第二周边部之间，因此，第一弯折部弯折时，不会在第一缺口位置处产生应力。从而能够减小柔性显示屏的非发光区多 重折叠，而导致应力集中的问题出现的几率。
可选的，柔性显示屏还包括多条数据线。第一周边部包括数据选择器以及与数据选择器耦接的多个焊盘。数据选择器用于与数据线耦接。当第一周边部沿垂直于转轴轴线方向弯折后，数据选择器和焊盘设置于柔性显示屏的背面。上述焊盘可以与驱动芯片耦接。这样一来第一周边部将设置有数据选择器和焊盘弯折至柔性显示屏的背面后，可以将尺寸较大的驱动芯片设置于柔性显示屏的背面，从而可以减小柔性显示屏的边框尺寸。同理，第二周边部上设置有数据选择器和焊盘的部分也可以弯折至柔性显示屏的背面。在第一周边部和第二周边部之间的第一缺口的间隔作用下，当第一周边部和第二周边部单独弯折时，可以减小不同周边部上用于耦接驱动芯片的部分出现拉扯或者起皱等现象的几率。
可选的，柔性显示屏还包括扇出部。该扇出部位于发光区和周边部之间。扇出部包括多条扇出引线。一条扇出引线的第一端与数据选择器相耦接，第二端和一条数据线相耦接。其中，靠近第一缺口的扇出引线，绕开第一缺口的边缘设置。这样一来，柔性显示屏上的数据线通过扇出部中的扇出引线与周边部上的数据选择器耦接时，可以通过绕开第一缺口的边缘的方式，使得数据线能够正常的接收数据电压，以使得柔性显示屏能够正常显示，而不会受到第一缺口的影响。
可选的，柔性显示屏还包括第三周边部、第四周边部以及第二缺口。第二缺口位于第三周边部和第四周边部之间，第三周边部、第四周边部与第一周边部位于非发光区的同一侧。第三周边部和第四周边部弯折至柔性显示屏背面的部分，均朝向第一壳体。这样一来，可以进一步增加非发光区的分段数量，以减少非发光区弯折部分的长度，提高弯折的良率。
可选的，第一缺口和第二缺口的形状相同。此外，沿与转轴轴线垂直的方向，第一缺口和第二缺口的开口宽度相同。这样一来，在柔性显示屏上形成第一缺口和第二缺口的制作工艺以及工艺参数可以相同，从而能够简化上述制作工艺。
可选的，沿与转轴轴线垂直的方向，第一缺口的开口宽度大于第一弯折部的宽度。这样一来，当第一周边部和第二周边部上各自用于与驱动芯片耦接的部分分别弯折柔性显示屏的背面后，再在柔性显示屏对应第一弯折部的位置对该柔性显示屏进行对折时，第一弯折部所在的位置不会对与第一周边部和第二周边部弯折至柔性显示屏背面的部分进行挤压，以减小其出现拉扯或者起皱等现象的几率。
可选的，发光区为矩形，且第一周边部和第二周边部位于发光区的长边。这样一来，与上述周边部上的驱动芯片耦接的各条数据线沿转轴轴线，即发光区的短边设置。相对于将数据线沿与转轴轴线垂直的方向，即发光区的长边设置的方案而言，能够大大缩减数据线的走线长度，从而降低数据线传输信号的损耗，以及负载电阻，提升驱动芯片的驱动能力，达到改善由于数据线在传输信号的过程中，出现信号延时导致的显示不均。
可选的，柔性显示屏还包括第一栅极驱动电路和第二栅极驱动电路。该第一栅极驱动电路在非发光区内，设置于发光区的第一短边所在的一侧。第一栅极驱动电路用于向发光区的至少一部分提供栅极驱动信号。第二栅极驱动电路在非发光区内，设置于发光区的第二短边所在的一侧。第二栅极驱动电路用于向发光区的至少一部分提供 栅极驱动信号。其中，第一短边和第二短边相对设置。第一栅极驱动电路和第二栅极驱动电路可以集成于柔性显示屏的柔性衬底上。因此相对于单独耦接栅极驱动芯片的方案而言，可以减小柔性显示屏左、右两边的边框的宽度，从而实现窄边框设计。
可选的，沿第二方向，第一栅极驱动电路和第二栅极驱动电路的宽度相同。这样一来，柔性显示屏左、右两边的边框的宽度也可以相同。从而使得柔性显示屏发光区左、右两边对称，有利于提升屏幕整体美观性。
可选的，显示终端还包括与焊盘相耦接的驱动芯片。该驱动芯片可以将数据信号通过焊盘提供至柔性显示屏的数据线上。本申请实施例的第二方面，提供一种柔性显示屏。柔性显示屏的背面用于与支撑组件中的第一壳体、第二壳体以及转轴相连接。其中，转轴位于第一壳体和第二壳体之间。第一壳体和第二壳体通过转轴转动连接。柔性显示屏中与转轴相连接的部分作为第一弯折部。第一弯折部用于沿转轴轴线的方向弯折，将柔性显示屏中分别与第一壳体和第二壳体相连接的部分对折。柔性显示屏具有发光区以及设置于发光区周边的非发光区。此外，柔性显示屏包括第一周边部和第二周边部。第一周边部和第二周边部在非发光区内，并排设置于发光区的同一侧。第一周边部弯折至柔性显示屏背面的部分朝向第一壳体。第二周边部弯折至柔性显示屏背面的部分朝向第二壳体。第一缺口在非发光区内，设置于第一弯折部的一侧，且位于第一周边部和第二周边部之间。这样一来，通过设置上述第一缺口，可以将柔性显示屏的非发光区中用于与驱动芯片相耦接的部分，进行分段形成多个上述周边部，例如，第一周边部和第二周边部。通过对每个周边部单独进行弯折，可以减少非发光区弯折部分的长度，提高弯折的良率。此外，由于第一缺口位于第一弯折部的一侧，且设置于第一周边部和第二周边部之间，因此，第一弯折部弯折时，不会在第一缺口位置处产生应力。从而能够减小柔性显示屏的非发光区多重折叠，而导致应力集中的问题出现的几率。
可选的，柔性显示屏还包括多条数据线。第一周边部包括数据选择器以及与数据选择器耦接的多个焊盘。数据选择器用于与数据线耦接。当第一周边部沿垂直于转轴轴线方向弯折后，数据选择器和焊盘设置于柔性显示屏的背面。上述焊盘可以与驱动芯片耦接，这样一来第一周边部将设置有数据选择器和焊盘弯折至柔性显示屏的背面后，可以将尺寸较大的驱动芯片设置于柔性显示屏的背面，从而可以减小柔性显示屏的边框尺寸。同理，第二周边部上设置有数据选择器和焊盘的部分也可以弯折至柔性显示屏的背面。在第一周边部和第二周边部之间的第一缺口的间隔作用下，当第一周边部和第二周边部单独弯折时，可以减小不同周边部上用于耦接驱动芯片的部分出现拉扯或者起皱等现象的几率。
可选的，柔性显示屏还包括扇出部。该扇出部位于发光区和周边部之间。扇出部包括多条扇出引线。一条扇出引线的第一端与数据选择器相耦接，第二端和一条数据线相耦接。其中，靠近第一缺口的扇出引线，绕开第一缺口的边缘设置。这样一来，柔性显示屏上的数据线通过扇出部中的扇出引线与周边部上的数据选择器耦接时，可以通过绕开第一缺口的边缘的方式，使得数据线能够正常的接收数据电压，以使得柔性显示屏能够正常显示，而不会受到第一缺口的影响。
可选的，柔性显示屏还包括第三周边部、第四周边部以及第二缺口。第二缺口位 于第三周边部和第四周边部之间，第三周边部、第四周边部与第一周边部位于非发光区的同一侧。第三周边部和第四周边部弯折至柔性显示屏背面的部分，均朝向第一壳体。这样一来，可以进一步增加非发光区的分段数量，以减少非发光区弯折部分的长度，提高弯折的良率。
可选的，第一缺口和第二缺口的形状相同。此外，沿与转轴轴线垂直的方向，第一缺口和第二缺口的开口宽度相同。这样一来，在柔性显示屏上形成第一缺口和第二缺口的制作工艺以及工艺参数可以相同，从而能够简化上述制作工艺。
可选的，沿与转轴轴线垂直的方向，第一缺口的开口宽度大于第一弯折部的宽度。这样一来，当第一周边部和第二周边部上各自用于与驱动芯片耦接的部分分别弯折柔性显示屏的背面后，再在柔性显示屏对应第一弯折部的位置对该柔性显示屏进行对折时，第一弯折部所在的位置不会对与第一周边部和第二周边部弯折至柔性显示屏背面的部分进行挤压，以减小其出现拉扯或者起皱等现象的几率。
可选的，发光区为矩形，且第一周边部和第二周边部位于发光区的长边。这样一来，与上述周边部上的驱动芯片耦接的各条数据线沿转轴轴线，即发光区的短边设置。相对于将数据线沿与转轴轴线垂直的方向，即发光区的长边设置的方案而言，能够大大缩减数据线的走线长度，从而降低数据线传输信号的损耗，以及负载电阻，提升驱动芯片的驱动能力，达到改善由于数据线在传输信号的过程中，出现信号延时导致的显示不均。
可选的，柔性显示屏还包括第一栅极驱动电路和第二栅极驱动电路。该第一栅极驱动电路在非发光区内，设置于发光区的第一短边所在的一侧。第一栅极驱动电路用于向发光区的至少一部分提供栅极驱动信号。第二栅极驱动电路在非发光区内，设置于发光区的第二短边所在的一侧。第二栅极驱动电路用于向发光区的至少一部分提供栅极驱动信号。其中，第一短边和第二短边相对设置。第一栅极驱动电路和第二栅极驱动电路可以集成于柔性显示屏的柔性衬底上。因此相对于单独耦接栅极驱动芯片的方案而言，可以减小柔性显示屏左、右两边的边框的宽度，从而实现窄边框设计。
可选的，沿第二方向，第一栅极驱动电路和第二栅极驱动电路的宽度相同。这样一来，柔性显示屏左、右两边的边框的宽度也可以相同。从而使得柔性显示屏发光区左、右两边对称，有利于提升屏幕整体美观性。

具体实施方式
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描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
以下，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”等的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
此外，本申请中，“上”、“下”、“左”、“右”等方位术语可以包括但不限于相对附图中的部件示意置放的方位来定义的，应当理解到，这些方向性术语可以是相对的概念，它们用于相对于的描述和澄清，其可以根据附图中部件附图所放置的方位的变化而相应地发生变化。
在本申请中，除非另有明确的规定和限定，术语“连接”应做广义理解，例如，“连 接”可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连。此外，术语“耦接”可以是实现信号传输的电性连接的方式。
本申请实施例提供一种显示终端，该显示终端可以为手机、显示器、平板电脑、车载电脑等具有显示界面的产品，以及智能手表、智能手环等智能显示穿戴产品。本申请实施例对上述显示终端的具体形式不做特殊限制。
上述显示终端01如图1a所示可以包括柔性显示屏10以用于对该柔性显示屏10进行支撑的支撑组件70。其中，上述支撑组件70包括第一壳体701、第二壳体702以及转轴703。该转轴703位于第一壳体701和第二壳体702之间。第一壳体701和第二壳体702可以通过转轴703转动连接。
基于此，上述柔性显示屏10的背面(即该柔性显示屏10朝向支撑组件70的一侧表面)与第一壳体701、第二壳体702以及转轴703相连接。该柔性显示屏10中与转轴703相连接的部分作为第一弯折部300。在此情况下，当第一壳体701和第二壳体702通过转轴703相对运动时，第一弯折部300可以沿转轴703轴线O-O的方向弯折，将柔性显示屏10中分别与第一壳体701和第二壳体702相连接的部分对折，从而实现柔性显示屏10的弯折。
此外，柔性显示屏10如图1b所示，具有发光区101以及设置于周边的非发光区102。柔性显示屏10的发光区101内设置有多个呈矩阵形式排列的亚像素(sub pixel)20。
为了方便说明，本申请中将将沿第一方向Y排列的一排亚像素20称为一列亚像素，沿第二方向X排列的一排亚像素20称为一行亚像素。第一方向Y和第二方向X垂直设置。该亚像素内20内设置有发光器件，例如OLED器件201。
上述OLED器件201制作于如图2所示的柔性衬底11上。构成该柔性衬底11的材料可以包括聚对苯二甲酸类塑料(polyethylene terephthalate，PET)。
需要说明的是，上述柔性显示屏10可以为有源矩阵驱动有机发光二极管(active matrix driving OLED，AMOLED)显示屏。相对于无源矩阵驱动有机发光二极管(passive matrix driving OLED，PMOLED)显示屏而言，AMOLED柔性显示屏无需向每个发光器件102提供很大的瞬态电流，更加省电，且更适合应用于大尺寸、高分辨率的显示终端中。
此外，OLED器件201能够自发光，该OLED器件201具有如图2所示的有机发光层120，以及分别位于该有机发光层120两侧的第一电极121和第二电极122。为了方便说明，在本申请实施例中，第一电极121为OLED器件201的阳极(anodic，a)，第二电极122为OLED器件201的阴极(cathode，c)。
在本申请的一些实施例中，构成第一电极121的材料可以为透明导电材料，例如，氧化铟锡(indium tin oxide，ITO)、氧化铟锌(indium zinc oxide，IZO)。构成第二电极122的材料可以为金属材料，例如铝(Al)、锰(Mg)等。此时，第一电极121透光率较大，第二电极122的透光率较小，因此柔性显示屏10发出的光线由第一电极121所在的一侧出射。该柔性显示屏10可以为底发光型显示屏。
反之，当构成第一电极121的材料为上述金属材料，构成第二电极122的材料为上透明导电材料时，柔性显示屏10发出的光线由第二电极122所在的一侧出射。该柔 性显示屏10可以为顶发光型显示屏。
基于此，OLED器件201的发光原理为，向有机发光层120两侧的第一电极121和第二电极122施加电压后，第一电极121和第二电极122中的载流子在有机发光层120中相遇，并激发出光子，从而使得有机发光层120发光。此时，上述OLED器件201发光，具有多个上述OLED器件201的柔性显示屏10进行画面显示。
各个亚像素20中OLED器件201的阴极c，即上述第二电极122通常接收相同的电压，例如公共接地端电压ELVSS。因此，如图2所示，位于不同亚像素20的各个OLED器件201的第二电极122可以电连接在一起，为一体结构，形成一层阴极层。该阴极层覆盖所有OLED器件201的有机发光层120。
此外，柔性显示屏10在显示图像的过程中，不同的亚像素20发出的光线颜色或者亮度可以不相同。在此情况下，需要将不同亚像素20中的第一电极121，以及有机发光层120进行隔离，以使得单个OLED器件201能够实现独立控制。
在此情况下，上述柔性显示屏10如图2所示，还包括像素定义层(pixel define layer，PDL)21。该像素定义层21具有多个凹槽12，一个凹槽12的底部露出一个第一电极121。从而可以使得多个第一电极121间隔设置于柔性衬底11上。
为了向各个第一电极121单独供电，如图3所示，每个亚像素20内还设置有的像素驱动电路02。该像素驱动电路02包括多个晶体管，例如薄膜晶体管(thin film transistor，TFT)以及至少一个电容。
图3中，是以像素驱动电路02包括OLED器件以及两个晶体管，T1和T2以及一个电容C为例进行的说明。其中，晶体管T1的栅极耦接栅线(gate line，GL)，第一极例如源极(source，s)耦接数据线(data line，DL)，第二极例如漏极(drain，d)耦接晶体管T2的栅极g。
晶体管T2的第一极，例如源极s与电压端ELVDD耦接，第二极，例如漏极d与OLED器件的阳极a耦接。该OLED器件的阴极c与电压端ELVSS耦接。当通过向栅线GL提供栅极驱动信号控制晶体管T1导通后，可以将数据电压Vdata，通过数据线DL传输至晶体管T2的栅极(gate，g)，从而使得该晶体管T2作为驱动晶体管驱动OLED器件发光。
每一条栅线GL与位于同一行(沿第二方向X)的亚像素20中晶体管T1的栅极g耦接。每一条数据线与位于同一列(沿第一方向Y)的亚像素20晶体管T1的源极s耦接。因此，当栅线GL逐行输入栅极驱动信号后，所有数据线DL可以向同一行亚像素20中各个晶体管T1的源极s提供数据电压Vdata。
需要说明的是，上述是以像素电路02中用于驱动OLED器件发光的部分包括两个晶体管和一个电容为例进行的说明。为了使得像素电路02具备更多的功能，例如，复位功能、阈值电压补偿功能等，还可以在像素电路02中增加其他晶体管。本申请对该像素电路02的结构不做限定。
由上述可知，通过位于不同亚像素20内的各个像素电路02，可以向每个OLED器件的第一电极121提供独立的电压，以单独控制OLED器件的发光亮度。此外，可以在不同的凹槽12内蒸镀不同材料的有机发光层120，以对单个OLED器件的发光颜色进行独立控制。
例如，在相邻的三个如图2所示的亚像素20构成一个像素(pixel)时，上述相邻的三个亚像素20中的OLED器件201可以分别发出红色(red，R)、绿色(green，G)以及蓝色(blue，B)的光线。
基于此，由上述可知，柔性显示屏10中与转轴703相连接的部分为第一弯折部300。当第一弯折部300沿转轴703轴线O-O的方向(与如4a所示的第一方向Y平行)弯折时，可以将柔性显示屏10中分别与第一壳体701和第二壳体702相连接的部分对折。以下为了方便说明，将该柔性显示屏10中与第一壳体701相连接的部分称为第一显示部200a，柔性显示屏10中与第二壳体702相连接的部分称为如图4a所示的第二显示部200b。
由于转轴703位于第一壳体701和第二壳体702之间，所以如图4b所示，第一弯折部300位于第一显示部200a和第二显示部200b之间。第一显示部200a和第二显示部200b内设置有上述亚像素，可以独立控制第一显示部200a和第二显示部200b进行画面显示。
为了简化制作工艺，可以在制作上述第一显示部200a和第二显示部200b内的亚像素20中的像素电路02时，同时在第一弯折部300内形成上述像素电路02。基于此，当第一弯折部300不需要进行显示时，在本申请的一些实施例中，可以将第一弯折部300中的数据线DL与用于向该数据线DL提供数据电压Vdata的驱动电路断开即可。
或者，在本申请的另一些实施例中，当第一弯折部300中的数据线DL与用于向该数据线DL提供数据电压Vdata的驱动电路耦接时，可以控制第一弯折部300显示黑色画面，或者与显示部显示的背景图一致的图案。
需要说明的是，本申请对相邻两个显示部，例如第一显示部200a和第二显示部200b通过第一弯折部300进行对折的方式不做限定。例如第一显示部200a和第二显示部200b在对折时，第一显示部200a的显示面可以朝向第二显示部200b的显示面。在此情况下，上述柔性显示屏10为内折式显示屏。或者，第一显示部200a的背面(即非现实面)可以朝向第二显示部200b的背面。在此情况下，上述柔性显示屏10为外折式显示屏。
图4a是根据支撑组件70的结构，将柔性显示屏10中第一弯折部300两侧的部分称为第一显示部200a和第二显示部200b为例进行的说明。
在本申请的另一些实施例中，当支撑组件70再增加一个转轴和壳体时，柔性显示屏10中与上述增加的转轴相连接的部分可以作为如图5a所示的第一弯折部300b。在此情况下，柔性显示屏10中，第一弯折部300b两侧的部分可以称为第二显示部200b和第三显示部200c。
如图5b所示，该第一弯折部300a用于沿第一方向Y弯折，将第一显示部200a和第二显示部200b对折，示例的，第一显示部200a的背面可以朝向第二显示部200b的背面。该第一弯折部300b用于沿第一方向Y弯折，将第二显示部200b和显示部200c对折，示例的，第二显示部200b的显示面可以朝向显示部200c的显示面。在此情况下，上述柔性显示屏10为内外折式显示屏。
此外，上述显示终端还包括如图6a所示的栅极驱动电路30。该栅极驱动电路30设置于柔性显示屏10的非发光区102内。其中，该非发光区102设置于柔性显示屏 10的发光区101的周边。
栅极驱动电路30与各条栅线GL耦接，用于向栅线GL提供栅极驱动信号。在本申请的一些实施例中，为了减小柔性显示屏10的边框尺寸，可以采用阵列基板行驱动(gate driver on array，GOA)技术，将主要用于构成栅极驱动电路30的TFT集成在该柔性显示屏10的柔性衬底11上。从而可以在柔性衬底11上制作像素电路02中的各个TFT时，即可以完成栅极驱动电路30中TFT的制备。
在本申请的一些实施例中，在柔性显示屏10的发光区101为矩形的情况下，当该发光区101的长边与短边的长度相差较大时，例如如图6b所示，发光区101沿第二方向X的长边(例如，相对设置的第一长边L1、第二长边L2)的长度与沿第一方向Y的短边(例如，相对设置的第一短边L3和第二短边L4)的长度相差较大时，上述栅极驱动电路可以包括位于发光区101两侧的第一栅极驱动电路30a和第二栅极驱动电路30b。
其中，第一栅极驱动电路30a设置于发光区101的第一短边L3所在的一侧。第二栅极驱动电路30b设置于发光区101的第二短边L4所在的一侧。如图6c所示，第一栅极驱动电路30a与栅线GL耦接，用于向发光区101的至少一部分提供栅极驱动信号。第二栅极驱动电路30b与栅线GL耦接，用于向发光区101的至少一部分提供栅极驱动信号。
需要说明的是，第一栅极驱动电路30a用于向发光区101的至少一部分提供栅极驱动信号，第二栅极驱动电路30b向发光区101的至少一部分提供栅极驱动信号是指，在本申请的一些实施例中，第一栅极驱动电路30a可以与偶数行的栅线GL耦接，以偶数行亚像素20提供栅极驱动信号。第二栅极驱动电路30b可以与奇数行的栅线GL耦接，以向奇数行亚像素20提供栅极驱动信号。
或者，在本申请的另一些实施例中，当第一栅极驱动电路30a与图6c所示的发光区101中对应第一显示部200a所在位置的各行栅线GL耦接，第二栅极驱动电路30b与发光区101中对应第二显示部200b所在位置的各行栅线GL耦接时，第一栅极驱动电路30a可以向第一显示部200a中各行亚像素20提供栅极驱动信号。第二栅极驱动电路30b可以向第二显示部200b中各行亚像素20提供栅极驱动信号。
或者，在本申请的另一些实施例中，当第一栅极驱动电路30a与图6c所示的发光区101中的各行栅线GL耦接，第二栅极驱动电路30b与发光区101中的各行栅线GL耦接时，第一栅极驱动电路30a可以从左至右，向发光区101中各行亚像素20提供栅极驱动信号。第二栅极驱动电路30b可以从右至左向发光区101中各行亚像素20提供栅极驱动信号。
此外，由上述可知，第一栅极驱动电路30a和第二栅极驱动电路30b可以采用GOA技术集成于柔性衬底11上。因此相对于单独耦接栅极驱动芯片的方案而言，可以减小柔性显示屏10左、右两边的边框的宽度，从而实现窄边框设计。
在此基础上，沿第二方向X，上述第一栅极驱动电路30a的宽度H1可以与第二栅极驱动电路30b的宽度H2可以相同。这样一来，柔性显示屏10左、右两边的边框的宽度也可以相同。从而使得柔性显示屏10的发光区101左、右两边对称，有利于提升屏幕整体美观性。
此外，在上述显示终端还包括驱动芯片，例如显示驱动芯片(display driver integrated circuit，DDIC)的情况下，使得数据线DL能够与用于提供数据电压Vdata的驱动芯片耦接，或者还可以称为邦定(banding)，该柔性显示屏10，如图7a所示还包括多个位于非发光区102内的第一周边部40a和第二周边部40b。其中，上述第一周边部40a和第二周边部40b并排设置于发光区101的同一侧。其中，第一周边部40a弯折至柔性显示屏10的背面的部分朝向上述第一壳体701，该部分可以通过粘接层固定于柔性显示屏10中第一显示部200a的背面。此外，第二周边部40b弯折至柔性显示屏10的背面的部分朝向上述第二壳体702，该部分可以通过粘接层固定于柔性显示屏10中第二显示部200b的背面。
在本申请的一些实施例中，如图7b所示，上述第一周边部40a、第二周边部40b中任意一个周边部包括数据选择器(multiplexer，MUX)411以及多个与MUX411相耦接的焊盘(pad)412。该MUX411用于与柔性显示屏10中的数据线DL耦接，焊盘412用于与如图7c所示的驱动芯片31相耦接。
当上述周边部沿垂直于转轴703轴线O-O方向(即上述第二方向X)弯折后，
MUX411和上述焊盘412设置于柔性显示屏10的背面。由于周边部上设置有焊盘412的部分用于与外部的驱动芯片31相耦接，所以本申请中可以将周边部上设置有焊盘412的部分称为外部引线连接部(outer lead bonding，OLB)401。
此外，在显示终端还包括如图7c所示的柔性电路板(flexible printed circuit，FPC)32时，上述OLB401上的部分焊盘412还用于耦接FPC32。在此情况下，柔性电路板FPC与驱动芯片31相耦接，驱动芯片31与通过MUX411与各条数据线DL耦接，用于向各条数据线DL提供数据电压。
图7c是以第一周边部40a、第二周边部40b中任意一个周边部上设置有一个
MUX411、一个驱动芯片31以及一个FPC32为例进行的说明。在本申请的另一些实施例中，当一行(沿第二方向X)亚像素20的数量较多时，一个驱动芯片31用于输出数据电压Vdata的数据电压输出端的数量不能够满足柔性显示屏10中数据线DL的数量要求时，如图7d所示，第一周边部40a、第二周边部40b中任意一个周边部上可以设置至少两组驱动单元，每一个驱动单元包括耦接的一个MUX411、一个驱动芯片31以及一个FPC32。
基于此，在上述显示终端还包括设置于印刷电路板(printed circuit board，PCB)，以及安装于该PCB上的片上系统(System on Chip，SoC)的情况下。该SoC内可以设置有应用处理器(application processor，AP)。图7c所示的驱动芯片31通过FPC32与SoC耦接。
这样一来，可以使得SoC输出的显示数据通过驱动芯片31后，转换成数据电压Vdata。MUX411可以根据需要在一个时间段内，只选择部分数据线DL分别接收驱动芯片31的各个数据电压输出端输出的数据电压Vdata。接下来，各个像素电路02通过数据线DL上的数据电压Vdata，生成与该数据电压Vdata相匹配的驱动电流I，以驱动亚像素20中的OLED器件201发光。
需要说明的是，当上述驱动芯片31为DDIC时，该驱动芯片31还可以与上述栅极驱动电路，例如第一栅极驱动电路30a和第二栅极驱动电路30b耦接，从而使得驱 动芯片31可以控制栅极驱动电路30输出的栅极驱动信号的时序。
此外，如图7b所示，第一周边部40a、第二周边部40b中任意一个周边部中，位于OLB401与发光区101之间的部分用于使得周边部可以弯折。为了方便说明，该部分可以称为上述周边部的第二弯折部402。
上述第一周边部40a中的第二弯折部402用于沿上述第二方向X弯折，从而如图8a所示将第一周边部40a中的OLB401弯折至柔性显示屏10的第一显示部200a的背面。此外，如图8b所示，第二周边部40b中的第二弯折部402用于沿第二方向弯折，将第二周边部40b中的OLB401弯折至柔性显示屏10的第二显示部200b的背面。这样一来，可以减少柔性显示屏10中，上述第一周边部40a和第二周边部40b所在一侧的边框的尺寸。
基于此，如图7b所示，在发光区101为如图6b所示的矩形时，上述第一周边部40a和第二周边部40b可以位于发光区101的长边，例如第二长边L2所在的一侧。这样一来，与上述周边部上的驱动芯片31耦接的各条数据线DL如图7d所示，沿第一方向Y，即发光区101的短边(如图6b中的第一短边L3和第二短边L4)设置。相对于将数据线DL沿第二方向X，即发光区101的长边设置的方案而言，能够大大缩减数据线DL的走线长度，从而降低数据线DL传输信号的损耗，以及负载电阻RC，提升驱动芯片31的驱动能力，达到改善由于数据线DL在传输信号的过程中，出现信号延时导致的显示不均。
在此基础上，柔性显示屏10还包括如图7d所示的第一缺口50。该第一缺口50在非发光区102内，设置于第一弯折部300的一侧，即一个第一弯折部300所在的位置下方，对应设置有一个第一缺口50。此外上述第一缺口50还位于第一周边部40a和第二周边部40b之间。上述第一缺口50用于将第一周边部40a和第二周边部40b间隔开。
这样一来，通过设置上述第一缺口50，可以将柔性显示屏10的非发光区102中用于与驱动芯片31和FPC32耦接的部分，即OLB所在的部分进行分段形成多个上述周边部，例如上述第一周边部40a和第二周边部40b。通过对每个周边部单独进行弯折(pad bending)，可以减少非发光区102弯折部分的长度(即沿第二方向X的尺寸)，提高弯折的良率。
此外，由于第一缺口50位于第一弯折部300的一侧，且设置于第一周边部40a和第二周边部40b之间，因此，当第一弯折部300弯折时，不会在第一缺口50位置处产生应力。从而能够减小柔性显示屏10的非发光区102多重折叠，而导致应力集中的问题出现的几率。
并且，如图8b所示，第一周边部40a的第二弯折部402弯折，以将第一周边部40a的OLB401翻转至柔性显示屏10的第一显示部200a的背面。第二周边部40b的第二弯折部402弯折，以将第二周边部40bOLB401b翻转至柔性显示屏10的第二显示部200b的背面。然后。再将第一显示部200a和第二显示部200b通过第一弯折部300进行对折。此时，该第一弯折部300弯折的过程中，在第一缺口50将第一周边部40a和第二周边部40b间隔的作用下，减小第一周边部40a的OLB401和第二周边部40b的OLB401出现拉扯或者起皱等现象出现的几率。
在此基础上，在本申请的一些实施例中，沿如图7d所示的第二方向X，第一缺口50的开口宽度，大于第一弯折部300的宽度。这样一来，当第一周边部40a的OLB401和第二周边部40b的OLB401分别弯折至第一显示部200a和第二显示部200b的背面后，再对第一显示部200a和第二显示部200b通过第一弯折部300进行对折时，第一弯折部300所在的位置不会对第一周边部40a的OLB401和第二周边部40b的OLB401进行挤压，以减小其出现拉扯或者起皱等现象的几率。
需要说明的是，上述是以柔性显示屏10中具有一个第一弯折部300以及位于该第一弯折部300两侧的如图8b所示两个能够独立显示的显示部，即第一显示部200a和第二显示部200b为例，对位于第一周边部40a和第二周边部40b之间的第一缺口50的设置方式进行的举例说明。
在本申请的另一些实施例中，如图9a所示，当柔性显示屏10包括两个第一弯折部，例如第一弯折部300a和第一弯折部300b时，同上所述，柔性显示屏10中可以设置三个能够独立显示的显示部，即第一显示部200a、第二显示部200b、第三显示部200c。基于此，柔性显示屏10可以包括三个周边部，分别为周边部A、周边部B以及周边部C。同理可得，相邻两个周边部之间可以设置一个第一缺口。示例的，周边部A、周边部B具有第一缺口50，周边部B与周边部C之间具有第一缺口50’。
在此情况下，对于周边部A和周边部B而言，该周边部A可以作为上述第一周边部40a，周边部B可以作为第二周边部40b。如图9b所示，周边部A和周边部B单独弯折，可以使得周边部A可以弯折至第一显示部200a的背面，周边部B可以弯折至第二显示部200b的背面。此外，对于周边部B和周边部C而言，该周边部C可以作为上述第一周边部40a，周边部B可以作为第二周边部40b。如图9b所示，周边部C和周边部B单独弯折，可以使得周边部C可以弯折至第三显示部200c的背面，周边部B可以弯折至第二显示部200b的背面。
以下为了方便说明，均是以柔性显示屏10具有如图8b所示两个显示部，即第一显示部200a和第二显示部200b为例进行的说明。
在本申请的另一些实施例中，如图10所示，柔性显示屏10还可以包括第三周边部40c、第四周边部40d以及第二缺口51。该第二缺口51位于第三周边部40c、第四周边部40d之间。第三周边部40c、第四周边部40d与上述第一周边部40a位于非发光区102的同一侧。上述第三周边部40c、第四周边部40d弯折至柔性显示屏10中的第一显示部200a的部分，均朝向上述第一壳体701。
此时，该第二缺口51可以用于将能够弯折至同一个显示部，例如第一显示部200a背面的第三周边部40c、第四周边部40d间隔开。从而能够进一步减少非发光区102弯折部分的长度，提高弯折的良率。
在本申请的一些实施例中，为了使得制作工艺简单，上述第一缺口50和第二缺口51的形状可以相同。此外，沿如图10所示的第二方向X，上述第一缺口50和第二缺口51的开口宽度可以相同。
或者，在另一些实施例中，第一缺口50和第二缺口51的形状，以及沿如图10所示的第二方向X，上述第一缺口50和第二缺口51的开口宽度还可以不同，本申请对此不作限定。
此外，在柔性显示屏10包括上述第一缺口50的情况下，为了使得柔性显示屏10中的数据线DL能够与第一周边部40a、第二周边部40b上的MUX411耦接时，不会受到上述第一缺口50的影响。如图11所示，上述柔性显示屏10还包括扇出部41。该扇出部41位于上述周边部和发光区101之间。
此外，上述扇出部41包括多条扇出引线SL。一条扇出引线SL的第一端与MUX411相耦接，第二端和一条数据线DL相耦接。其中，靠近第一缺口50的扇出引线SL，绕开上述第一缺口50的边缘设置。例如，靠近第一缺口50的扇出引线SL可以采用倾斜设置的方式，绕开上述第一缺口50的边缘。
基于此，由上述可知，当第一弯折部300需要进行显示时，该第一弯折部300内的数据线DL可以通过位于扇出部41内的扇出引线SL与用于向该数据线DL提供数据电压Vdata的DDIC耦接。一个第一弯折部300所在的位置下方，对应设置有一个第一缺口50。因此，扇出部41内用于将第一弯折部300内的数据线DL和DDIC耦接的扇出引线SL可以采用倾斜设置的方式，绕开上述第一缺口50的边缘。
同理，在柔性显示屏10包括上述第二缺口51的情况下，为了使得柔性显示屏10中的数据线DL能够与周边部上的MUX411耦接时，不会受到上述第二缺口51的影响。上述扇出部41中，靠近第二缺口51的扇出引线SL，可以绕开上述第二缺口51的边缘设置。
以下以如图7c所示的柔性显示屏10为例，对该柔性显示屏10的制作方法进行举例说明。
首先，设计即将制作于柔性衬底11上的像素电路01、外围驱动电路(例如MUX411以及选取驱动芯片31等)、OLB布局、可靠性器件和结构以及上述第一缺口50的位置与形状。
接下来，将液态的聚酰亚胺薄膜(polyimide，PI)材料涂布于如图12a所示的玻璃基板60上，并经过高温固化后，形成柔性基底11。
需要说明的是，为了便于将制作好的柔性显示屏10与玻璃基板60分离，在形成柔性衬底11之前，可以先在玻璃基板60上涂覆一层热释放胶(图中未示出)。
接下来，如图12b所示，通过构图工艺，例如黄光工艺(包括掩膜、曝光、显影、刻蚀等)制备出柔性衬底11的阵列基板61。该阵列基板61上形成有如图3所示的像素电路02中的各个TFT以及电容C。
接下来，如图12c所示，在上述阵列基板61上制作PDL21，以定义每个亚像素20中出OLED器件的位置。然后，采用精细掩模版工艺在阵列基板61上形成OLED器件201的阳极a。
接下来，如图12d所示，在形成有上述结构的柔性衬底11上，沉积有机/无机复合层形成位于各个亚像素20内的OLED器件。然后，形成封装层62。
接下来，对制作好的基板进行切割，并形成上述第一缺口50。
示例的，可以通过激光或刀轮(如图13所示)等切割工具63，对通过上述工艺形成的基板进行切割，以分离出各个独立的柔性显示屏10，并采用上述切割工具63在第一缺口50的设计位置采用缺口(notch)加工工艺、开槽工艺或者开缝工艺形成上述第一缺口50。然后采用激光对上述玻璃基板60上的热释放胶进行加热，以将柔 性衬底11与玻璃基板60分离。
接来下，采用模组工艺，在柔性显示屏10的上方完成偏光片、触摸屏等膜层的贴合，经过OLB工艺，将上述驱动芯片31以及FPC32的引脚(pin)，与柔性显示屏10非发光区102中的焊盘412(如图7b所示)进行脚对脚结合。然后，在该柔性显示屏10的背面设置强化背板，在触摸屏的触摸表面覆盖盖板。
最后，采用弯折工艺，将柔性显示屏10非发光区102中的第一周边部40a和第二周边部40b，弯折至柔性显示屏10的背面，从而完整了折叠显示终端的组装。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何在本申请揭露的技术范围内的变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
