在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接或可以相互通信；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
下文的公开提供了许多不同的实施方式或例子用来实现本发明的不同结构。为了简化本发明的公开，下文中对特定例子的部件和设定进行描述。当然，它们仅仅为示例，并且目的不在于限制本发明。此外，本发明可以在不同例子中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施方式和/或设定之间的关系。此外，本发明提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
请参阅图1，本发明实施方式的柔性屏模组10包括柔性屏12和连接件14。柔性屏12包括显示区122和非显示区124。非显示区124间隔设置有第一绑定区1241和第二绑定区1242。相对于第二绑定区1242，第一绑定区1241更靠近柔性屏12的边缘。连接件14连接第一绑定区1241。连接件14具有柔软、可弯曲等特点。
本发明实施方式的柔性屏12可以通过各向异性导电胶膜绑定工艺将柔性屏12和连接件14进行绑定。柔性屏12具有柔软、可弯曲等特点，若绑定区和连接件14中的至少一个存在质量问题导致绑定出现问题时，分离柔性屏12和连接件14可能会造成连接位置的金属垫脱落，而采用腐蚀剂腐蚀各向异性导电胶膜及使用擦拭工具清洁可能会损伤柔性屏12， 因此，难以对柔性屏12进行重新绑定。然而，连接件14为柔性材料，膨胀率不容易控制，来料的尺寸差异较大；柔性屏12和连接件14绑定制程中，通常包括热压工艺，受热后尺寸差异较大，容易产生偏移、短路、断路等质量问题，进而影响产品良率。
如此，柔性屏12的非显示区124设置有第一绑定区1241和第二绑定区1242，在柔性屏12与连接件14进行绑定时，连接件14可以与第一绑定区1241绑定。若第一绑定区1241与连接件14二者中的至少一个存在质量问题导致绑定出现问题时，则柔性屏12将第一绑定区1241切除后可以重新选择绑定第二绑定区1242。如此，可以解决因连接件14绑定不良而导致柔性屏12无法重新加工绑定的问题，有利于提高柔性屏模组10的良率。
具体地，柔性屏12切除第一绑定区1241时，可以采用离子切割机进行切除，可以减小柔性屏12热变形，并能够保持切割面平整。
在一个例子中，柔性屏12的第一绑定区1241和第二绑定区1242平行设置于显示区122的同一侧，第一绑定区1241与显示区122的距离大于第二绑定区1242和显示区122的距离。如此，柔性屏12切除第一绑定区1241，不影响柔性屏12重新选择绑定第二绑定区1242。当然，柔性屏12的第一绑定区1241和第二绑定区1242可以设置在显示区122的不同侧。柔性屏12切除第一绑定区1241，同样不影响柔性屏12重新选择绑定第二绑定区1242。
请参阅图2，在某些实施方式中，非显示区124自下至上包括基底层1243、缓冲层1244和金属层1245。金属层1245形成有第一绑定区1241和第二绑定区1242。
可以理解，金属层1245通常可以连接显示区122的开关器件区1222(如薄膜晶体管，Thin Film Transistor，TFT)，金属层1245的第一绑定区1241和第二绑定区1242可以与连接件14连接，如此，柔性屏12通过第一绑定区1241和第二绑定区1242传输电信号以控制柔性屏12开关器件区1222以及对应的像素工作。
当然，在其他实施方式中，绑定区的数量可以根据需要灵活配置。
在某些实施方式中，柔性屏12包括设置在金属层1245上的绝缘层1246。绝缘层1246间隔开设有第一通孔1246A和第二通孔1246B。金属层1245由第一通孔1246A露出的部位形成第一绑定区1241，由第二通孔1246B露出的部位形成第二绑定区1242。
如此，绝缘层1246可以保护金属层1245以避免金属层1245发生短路影响柔性屏12显示效果。同时，绝缘层1246可以形成有第一通孔1246A以便第一绑定区1241和连接件14连接。绝缘层1246可以形成有第二通孔1246B以便切除第一绑定区1241后，第二绑定区1242和连接件14连接。
在某些实施方式中，非显示区124包括设置在绝缘层1246上的保护层1247。保护层 1247覆盖第二通孔1246B并露出第一通孔1246A。
如此，连接件14连接第一绑定区1241时，第二绑定区1242闲置，此时，保护层1247和绝缘层1246可以密封第二绑定区1242使得第二绑定区1242不容易受到外部环境的影响而可以保持绑定功能。柔性屏12切除第一绑定区1241，并重新选择绑定第二绑定区1242时，可以撕除保护层1247以便第二绑定区1242露出并与连接件14连接。
请再次参阅图1，在某些实施方式中，金属层1245包括金属引线1245A、第一金属垫1245B和第二金属垫1245C。第一金属垫1245B位于第一通孔1246A处。第二金属垫1245C位于第二通孔1246B处。金属引线1245A分别连接第一金属垫1245B和第二金属垫1245C。
可以理解，柔性屏12通过金属层1245上的金属引线1245A传输电信号，然而，金属引线1245A在柔性屏12中通常较细，不容易与连接件14连接。如此，柔性屏12可以通过金属垫增加金属引线1245A与连接件14的接触面积以便柔性屏12和连接件14连接，同时，接触面积增加可以减小连接点的电阻，有利于电信号的传输。
具体地，在一个例子中，金属层1245可以包括多根金属引线1245A，多根金属引线1245A分别连接开关器件区1222的行线、列线，如此，可以精确控制柔性屏12对应的像素工作。相应地，金属层1245可以包括多个第一金属垫1245B和多个第二金属垫1245C，多个第一金属垫1245B和多个第二金属垫1245C的数量和金属引线1245A的数量对应。
其中，一根金属引线1245A可以同时连接一个第一金属垫1245B和一个第二金属垫1245C，可以节省金属引线1245A数量使得金属引线1245A布线空间更加灵活。
当然，在其他实施方式中，一根金属引线1245A可以连接一个第一金属垫1245B或一个第二金属垫1245C，如此，可以形成两组相互独立的金属引线1245A分别连接第一绑定区1241和第二绑定区1242，其中一组金属引线1245A出现问题时，另一组金属引线1245A可以实现电信号传输。
具体地，在一个例子中，金属引线1245A和金属垫可以是铜或银等导电率较高的金属。
在某些实施方式中，柔性屏模组10包括触摸层结构1224。触摸层结构1224覆盖显示区122。如此，触摸层结构1224可以保护显示区122的显示元件不容易受到损坏，同时，实现柔性屏12的触摸控制功能。
请参阅图3，在一些实施方式中，触摸层结构1224可以延伸至非显示区124并覆盖第二绑定区1242，露出第一绑定区1241。如此，触摸层结构1224同样可以在连接件14连接第一绑定区1241时，取代非显示区124的保护层1247以实现与绝缘层1246结合从而密封并保护第二绑定区1242。
在某些实施方式中，触摸层结构1224包括层叠设置的触控层1224A和偏光层1224B。
如此，触控层1224A可以通过检测用户触摸的区域以实现柔性屏12的触控功能。偏光层1224B可以过滤掉杂光，使得同向的有效光线进入视线，提高柔性屏12的颜色对比度，用户眼睛可以清晰地看到显示图像。其中，触控层1224A和偏光层1224B层叠设置的顺序在此不做具体限定。
请再次参阅图1，在某些实施方式中，连接件14为覆晶薄膜。覆晶薄膜上设置有驱动芯片142。驱动芯片142被配置成驱动柔性屏12工作。
如此，驱动芯片142可以通过晶粒软膜构装技术封装在覆晶薄膜上。驱动芯片142可以接收或发出电信号以控制柔性屏12工作。
请参阅图4，在某些实施方式中，连接件14包括第三绑定区144。第三绑定区144连接第一绑定区1241。
相应地，第三绑定区144可以包括多个金属垫，金属垫的数量和第一金属垫1245B、第二金属垫1245C的数量对应。连接件14连接第一绑定区1241后，第三绑定区144的金属垫可以和第一金属垫1245B一一对应连接，如此，可以在连接件14和柔性屏12之间传输电信号。
在某些实施方式中，柔性屏模组10包括柔性电路板16。柔性屏12通过连接件14连接柔性电路板16。
如此，柔性屏模组10还可以包括其他电子元件(如电容、电阻等)，柔性屏模组10的其他元件可以设置在柔性电路板16上，可以通过连接件14与柔性屏12连接以实现柔性屏12的显示功能。
相应地，在一些例子中，连接件14和柔性电路板16通过各向异性导电胶膜绑定工艺将连接件14和柔性电路板16进行绑定。具体的，连接件14和柔性电路板16分别具有相应的第四绑定区146和第五绑定区162。
请参阅图5，在某些实施方式中，连接件14呈弯曲状。柔性电路板16位于柔性屏12的下方。
如此，柔性屏12和柔性电路板16层叠设置，可以减少柔性屏模组10的平面面积，有利于优化柔性屏模组10的空间配置。
请参阅图6，本发明实施方式的一种电子装置100包括上述任一实施方式的柔性屏模组10，也即是说，本发明实施方式的柔性屏模组10可以应用于本发明实施方式的电子装置100。
本发明实施方式的电子装置100的柔性屏模组10通常连接柔性电路板16，在绑定位置和柔性电路上的其他元件因使用或其他原因出现问题时，柔性屏12可以切除第一绑定区 1241，并重新选择绑定第二绑定区1242。如此，可以避免柔性电路板16上的其他元件出现问题时需要更换整个柔性屏模组10，有利于减少电子装置100的维修成本。
具体地，在柔性屏12切除第一绑定区1241，并重新选择绑定第二绑定区1242时，柔性屏模组10的空间尺寸通常随之发生变化。如此，图6所示的电子装置100可以增加避位区域1320，柔性屏12切除第一绑定区1241，并重新选择绑定第二绑定区1242，如图7所示，柔性电路板16位置可以移动并占据预留的避位区域1320。当然，图8和图9所示的电子装置100的柔性屏12可以在重新绑定第二绑定区1242时增加连接件14的长度，柔性电路板16可以位于电子装置100内原来的位置。
请再次参阅图6，在某些实施方式中，电子装置100包括壳体120和覆盖膜110。柔性屏模组10位于壳体120内。壳体120开设有开口。覆盖膜110连接壳体120并密封开口。
如此，壳体120形成和覆盖膜110可以形成相对密闭的收容空间，柔性屏模组10和电子装置100的其他器件可以收容于收容空间内，使得柔性屏模组10和电子装置100的其他器件不容易受到外界环境的干扰，从而可以正常工作。
在一些例子中，电子装置100可以是手机、平板电脑等电子装置。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施方式，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
