上述柔性屏中，由于第一粘合区的表面和第二粘合区的表面中的至少一个表面形成有第一纹路区域，这样在采用粘合胶粘结第一粘合区和第二粘合区时，粘合胶能够渗入第一纹路区域一定深度，继而能够提高第一粘合区和第二粘合区粘结的强度，从而提高支撑板与柔性屏本体连接的粘结力，这样可避免或减少柔性屏弯折时的粘合胶脱落，并能够有效提高柔性电子装置整机的弯折寿命。

上述柔性屏的制备方法中，由于第一粘合区的表面和第二粘合区的表面中的至少一个表面形成有第一纹路区域，这样在采用粘合胶粘结第一粘合区和第二粘合区时，粘合胶能够渗入第一纹路区域一定深度，继而能够提高第一粘合区和第二粘合区粘结的强度，从而提高支撑板与柔性屏连接的粘结力，这样可避免或减少柔性屏弯折时的粘合胶脱落，并能够有效提高柔性电子装置整机的弯折寿命。

上述柔性电子装置中，由于第一粘合区的表面和第二粘合区的表面中的至少一个表面形成有第一纹路区域，这样在采用粘合胶粘结第一粘合区和第二粘合区时，粘合胶能够渗入第一纹路区域一定深度，继而能够提高第一粘合区和第二粘合区粘结的强度，从而提高支撑板与柔性屏本体连接的粘结力，这样可避免或减少柔性屏弯折时的粘合胶脱落，并能够有效提高柔性电子装置整机的弯折寿命。

请一并参阅图1-13，本发明实施方式的柔性屏10应用于本发明实施方式的柔性电子装置100。柔性电子装置100例如可为柔性折叠手机或者柔性折叠平板电脑等。柔性电子装置100包括本体20。柔性屏10设置于本体20上。柔性电子装置100能够在折叠状态和展开状态切换。
本发明实施方式的柔性屏10能够弯折。柔性屏10形成有弯折区11和连接在弯折区11的两个非弯折区12(弯折区11和两个非弯折区12由如图3及图6至图13所示的虚线区分)。柔性屏10包括层叠设置的柔性屏本体13和支撑板14。对应弯折区11的柔性屏本体13形成第一粘合区131。对应弯折区11的支撑板14形成第二粘合区132。第一粘合区131与第二粘合区132相对设置，并通过粘合胶101粘结在一起。第一粘合区131的表面和第二粘合区132的表面中的至少一个表面形成有第一纹路区域15。
本发明实施方式的柔性屏10能够由本发明实施方式的柔性屏的制备方法制备，柔性屏的制备方法包括：
在第一粘合区131的表面和第二粘合区132的表面中的至少一个表面形成第一纹路区域15；
将第一粘合区131与第二粘合区132连接以使柔性屏本体13层叠设置于支撑板14。
如此，由于第一粘合区131的表面和第二粘合区132的表面中的至少一个表面形成有第一纹路区域15，这样在采用粘合胶101粘结第一粘合区131和第二粘合区132时，粘合胶101能够渗入第一纹路区域15一定深度，继而能够提高第一粘合区131和第二粘合区132粘结的强度，从而提高支撑板14与柔性屏本体13连接的粘结力，这样可避免或减少柔性屏10弯折时的粘合胶101脱落，并能够有效提高柔性电子装置100整机的弯折寿命。可以理解，第一纹路区域15在粘合区131和粘合区132表面形成的深度可根据支撑板14的厚度或者柔性屏本体13的厚度进行调整。
需要说明的是，在本实施方式中，柔性屏10的弯折区11能够在折叠状态和展开状态切换。两个非弯折区12在柔性屏10弯折时整体相互靠近，在柔性屏10展开时整体相互远离。再有，在本实施方式中，支撑板14位于柔性屏本体13的一侧，支撑板14对柔性屏本体13具有一定支撑及保护作用。
可以理解，柔性屏10的形成可根据具体情况进行设置，例如可呈长方体状等。另外，连接第一粘合区131与第二粘合区132的粘合胶101可采用紫外光固化胶(UV胶)或者压敏胶水或者环氧树脂胶或者导电胶等。支撑板14可以采用金属制成，例如采用不锈钢材料制成。在本实施方式中，支撑板14整体呈片状。
另外，第一纹路区域15可整体呈规则的形状，也可呈不规则的形状，这可根据具体情况进行设置。例如，第一纹路区域15可呈长方体状。
在某些实施方式中，在第一粘合区131的表面和第二粘合区132的表面中的至少一个表面形成第一纹路区域15的步骤中，包括采用第一表面处理工艺处理第一粘合区131的表面和第二粘合区132的表面中的至少一个表面以形成第一纹路区域15。如此，由表面处理工艺形成的第一纹路区域15的接触面积较大，附着力较强，并且第一纹路区域 15的形成方式较简单，并且制备工艺步骤较少。
在本实施方式中，第一纹路区域15采用第一表面处理工艺形成。第一表面处理工艺例如为镭射处理工艺。如此，这样易于在弯折区11形成第一纹路区域15。
在某些实施方式中，在第一粘合区131的表面和第二粘合区132的表面中的至少一个表面形成纹路区域15的步骤中，还包括采用第二表面处理工艺处理第一纹路区域15的表面。
在本实施方式中，第一纹路区域15的表面采用第二表面处理工艺处理过，第二表面处理工艺例如为等离子处理工艺或电晕处理工艺。如此，第一纹路区域15的表面能得到增加，这样能够提高第一纹路区域的粘合力。
请结合图6至图9，在某些实施方式中，第一粘合区131的表面形成有第一纹路区域15a。如此，采用的粘合胶101能够渗入第一粘合区131一定深度(例如8-20微米左右)，利于柔性屏本体13和支撑板14的连接。
在某些实施方式中，第一纹路区域15a形成在整个第一粘合区131的表面。如此，形成的第一纹路区域15a的接触面积较大，粘合胶101能够渗入到整个第一粘合区131，这样能够提高柔性屏本体13连接支撑板14的粘结力。
请结合图6及图7，在某些实施方式中，第一纹路区域15a位于柔性屏本体13的一边侧。在图6所示的例子中，第一纹路区域15a位于柔性屏本体13的左边侧。在图7所示的例子中，第一纹路区域15a位于柔性屏本体13的右边侧。如此，在柔性屏本体13的一侧形成第一纹路区域15a能够简化柔性屏10的制备工艺。同时，第一纹路区域15a能够提高对应柔性屏本体13的一侧与支撑板14连接的粘结力。在图6及图7所示的例子的中，第一纹路区域15a呈网格图案状。如此，采用的粘合胶101能够较佳地渗入第一粘合区131，并且粘合胶101在第一纹路区域15a分布均匀。
请结合图8，在某些实施方式中，第一粘合区131形成于柔性屏本体13的两边侧。柔性屏本体13的两边侧均形成有第一纹路区域15a。如此，柔性屏本体13的两侧与支撑板14连接的粘结力均较佳。在图8所示的例子中，第一纹路区域15a呈线条图案状。如此，采用的粘合胶101能够较佳地渗入第一粘合区131，并且粘合胶101在第一纹路区域15a分布均匀。
请结合图10至图12，在某些实施方式中，第二粘合区132的表面形成第一纹路区域15b。如此，采用的粘合胶101能够渗入第二粘合区132一定深度，利于支撑板14和柔性屏本体13的连接。
在某些实施方式中，第一纹路区域15b形成在整个第二粘合区132的表面。如此，形成的第一纹路区域15b的接触面积较大，采用的粘合胶101能够渗入到整个第二粘合 区132，这样能够提高支撑板14连接柔性屏本体13的粘结力。
请结合图10及图11，在某些实施方式中，第一纹路区域15b位于支撑板14的一边侧。在图10所示的例子中，第一纹路区域15b位于支撑板14的左边侧。在图11所示的例子中，第一纹路区域15b位于支撑板14的右边侧。在支撑板14的一侧形成第一纹路区域15b能够简化柔性屏10的制备工艺。同时，第一纹路区域15b能够提高对应支撑板14的一侧与柔性屏本体13连接的粘结力。
请结合图12，在某些实施方式中，第二粘合区132形成于支撑板14的两边侧。支撑板14的两边侧均形成有第一纹路区域15b。如此，支撑板14的两侧与柔性屏本体13连接的粘结力均较佳。
在图10至图12所示的例子的中，第一纹路区域15b呈点状图案状。如此，采用的粘合胶101能够较均匀地渗入第二粘合区132，并且第一纹路区域15与粘合胶101的接触面积较大，使粘合胶101在第一纹路区域15能够均匀分布。
请结合图9及图13，在某些实施方式中，第一纹路区域15包括第二纹路区域151和第三纹路区域152。第一粘合区131的表面形成第二纹路区域151。第二粘合区132的表面形成第三纹路区域152。如此，柔性屏本体13和支撑板14均形成有纹路区域，这样柔性屏本体13与支撑板14连接的稳定性更佳。
在某些实施方式中，第二纹路区域151的形状与第三纹路区域152的形状相匹配。如此，采用的粘合胶101能够均匀渗入第二纹路区域151和第三纹路区域152，使第二纹路区域151和第三纹路区域152之间具有较佳的粘结力。
可以理解，“第二纹路区域151的形状与第三纹路区域152的形状相匹配”指的是在支撑板14贴合于柔性屏本体13时，第二纹路区域151的尺寸和第三纹路区域152的尺寸基本一致，并且第二纹路区域151的图案和第三纹路区域152的图案基本一致。
在某些实施方式中，第二纹路区域151位于柔性屏本体13的一边侧。第三纹路区域152位于支撑板14的一边侧。第二纹路区域151与第三纹路区域152相对。第二纹路区域151与第三纹路区域152位于弯折区11的同一侧。如此，第二纹路区域151与第三纹路区域152所对应的弯折区11的一侧的稳定性更佳。
在某些实施方式中，第二纹路区域151位于柔性屏本体13的一边侧。第三纹路区域152位于支撑板14的一边侧。第二纹路区域151与第三纹路区域152错开。第二纹路区域151与第三纹路区域152分别位于弯折区11的两侧。如此，弯折区11的两侧的稳定性均较佳。例如，第二纹路区域151能够位于柔性屏本体13的左边侧，而第三纹路区域152能够位于支撑板14的右边侧。其中，柔性屏本体13的左边侧与支撑板14的左边侧对应连接，柔性屏本体13的右边侧与支撑板14的右边侧对应连接。这样第二 纹路区域151与第三纹路区域152为错开设置。
在某些实施方式中，第二纹路区域151包括两个第二子纹路区域1511。柔性屏本体13的两边侧的第一粘合区131的表面分别形成两个第二子纹路区域1511。第三纹路区域152包括两个第三子纹路区域1521。支撑板14的两边侧的第二粘合区132的表面分别形成两个第三子纹路区域1521。两个第二子纹路区域1511分别与两个第三子纹路区域1521对应。例如，在图9及图13所示例子的中，两个第二子纹路区域1511分别位于柔性屏本体13的左右两边侧。两个第三子纹路区域1521分别位于支撑板14的左右两边侧。
如此，采用的粘合胶101能够渗入到位于柔性屏本体13的两侧的第一粘合区131，并能够渗入到位于支撑板14的两侧的第二粘合区132，这样粘结后的柔性屏本体13和支撑板14所在的弯折区11的两侧的稳定性更佳。
请结合图5，在某些实施方式中，第一纹路区域15包括多个间隔设置的凹槽150。如此，采用的粘合胶101能够渗入各个凹槽150，这样凹槽150的设置增大了第一纹路区域15与粘合胶101的接触面积。
可以理解，凹槽150的深度可根据支撑板14的厚度或者柔性屏本体13的厚度进行对应设置。
在某些实施方式中，凹槽150贯通第一纹路区域15的侧面。如此，粘合胶101能够更均匀地渗入第一纹路区域15各处。
在某些实施方式中，两个非弯折区12中的至少一个非弯折区12形成有第四纹路区域16。第四纹路区域16连接第一纹路区域15。如此，采用的粘合胶101能够渗入非弯折区12一定深度，增大了柔性屏本体13与支撑板14粘结的附着点，能够进一步提高柔性屏本体13与支撑板14粘结的稳定性。
需要说明的是，第四纹路区域16可整体呈规则的形状，也可呈不规则的形状，这可根据具体情况进行设置。例如，第四纹路区域16可呈方体状。再有，第四纹路区域16能够单独形成于两个非弯折区12中的一个非弯折区12，也能够单独位于一个非弯折区12的一侧，也能够位于一个非弯折区12的两侧。两个非弯折区12均能够分别形成有第四纹路区域16。这可根据具体情况进行设置。
可以理解，第四纹路区域16可采用第一纹路区域15一样的处理方式。在本实施方式中，第一纹路区域15采用表面处理工艺处理，第一纹路区域15和第四纹路区域16构成一个整体的图案层。
在某些实施方式中，柔性屏本体13包括层叠设置的基板133和连接板134。对应弯折区11的连接板134的周缘区域构成第一粘合区131。连接板134连接基板133及支撑 板14。连接板134的设置对基板133具有支撑及保护的作用，并能够提高柔性屏10整体的稳定性。在第一个例子中，连接板134是液态金属支撑板。
在某些实施方式中，连接板134在基板133的正投影面积覆盖基板133。如此，连接板134对基板133的支撑及保护作用更佳。
在某些实施方式中，在柔性屏10弯折时，柔性屏本体13与支撑板14在弯折区11相对滑动。
在某些实施方式中，柔性屏10弯折时，在弯折区11的粘合胶101发生弹性拉伸形变。如此，粘合胶101不容易受力而脱落。
在某些实施方式中，柔性屏10在展开时，在弯折区11的粘合胶101恢复形变。如此，这样能够保证支撑板14与柔性屏本体13在柔性屏10多次弯折后的相互粘结力。
可以理解地，本发明的柔性屏本体13与支撑板14之间在弯折区11为非固定贴合，在其中一个非弯折区12为固定贴合，另一个非弯折区12为非固定贴合。即，在弯折区11粘合柔性屏本体13与支撑板14的粘合胶101没有完全固定住柔性屏本体13及支撑板14，二者相互之间仍可以相对滑动；在其中一个非弯折区12通过粘合胶101完全固定住柔性屏本体13与支撑板14，二者不可相对移动；在另一个非弯折区12未采用粘合胶101贴合柔性屏本体13与支撑板14，二者之间可自由相对滑动。当然，也可以仅在弯折区12通过粘合胶101非固定贴合，在两个非弯折区12不使用粘合胶101，具体取决于实际需求。在弯折时，由于弯折半径差异，柔性屏本体13与支撑板14在弯折区11会产生相对滑动，使得弯折区11内的粘合胶101发生弹性形变而被拉伸。当恢复展平状态时，柔性屏本体13与支撑板14在弯折区11会产生反方向的相对滑动，此时弯折区11内的粘合胶101恢复形变。进一步地，设于非弯折区12的粘合胶101的弹性可小于设于弯折区11的粘合胶101的弹性。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
上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，上文中对特定例子的部件和设置进行描述。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/或设置之 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。
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。
