S1：制备柔性显示屏11；
S2：制备柔性显示屏11的薄膜封装12的下膜层121，薄膜封装12包括下膜层121和上膜层122；
S3：提供金属掩膜，金属掩膜形成有通孔，通孔形成预定图案；
S4：利用金属掩膜在下膜层121上蒸镀形成触控电极135，触控电极135形成的图案与预定图案一致；和
S5：在触控电极135上制备上膜层122。
请参阅图2和图3，本发明实施方式的触控传感器13的制备方法用于在薄膜封装12内制备触控传感器13，薄膜封装12包括上膜层122和下膜层121，触控传感器13的制备方法包括步骤：
S3：提供金属掩膜，金属掩膜形成有通孔，通孔形成预定图案；
S4：利用金属掩膜在下膜层121上蒸镀形成触控电极135，触控电极135形成的图案与预定图案一致；和
S5：在触控电极135上制备上膜层122。
上述实施方式的显示屏组件10的制备方法和触控传感器13的制备方法中，触控电极135通过蒸镀的方式形成，在蒸镀形成触控电极135的过程中，薄膜封装12的膜层和柔性显示屏11不会受到损坏，提高了生产柔性显示屏11的良率。
显示屏组件10通常还包括设置在薄膜封装12上的偏光片14和盖板15，偏光片14和盖板15均可以是可弯曲的柔性板。为了减少显示屏组件10膜层的数量，降低显示屏组件10的整体厚度，可以将触控传感器13制备在薄膜封装12内。薄膜封装12用于封装柔性显示屏11以保护柔性显示屏11。柔性显示屏11可以是OLED显示屏。
显示屏组件10可用于手机、平板电脑、可穿戴设备等电子装置中，用户可通过显示屏组件10与电子装置进行交互，具体地，柔性显示屏11显示影像、文字等信息，用户接收到信息后，可在盖板15上进行触摸，触控传感器13检测用户在盖板15上的触摸位置以接收用户的特定输入。
触控传感器13包括多个触控电极135，用户在盖板15的特定位置触摸时，改变对应位置的触控电极135的电势，触控电路18检测触控电极135的电势变化以定位用户触控的位置。多个触控电极135形成预定的图案，图案的类型依据电子装置的类型有不同，多个触控电极135之间往往需要互相间隔。故如果在薄膜封装12上形成连续的触控电极板，则还需要将触控电极板的部分材料镂空以形成预定的图案，例如可以使用溶剂蚀刻或者使用激光切割的方法将电极板中多余的材料去除，而薄膜封装12和柔性显示屏11容易在去除多余材料的过程中被损坏。
通过蒸镀的方法直接在下膜层121上形成具有预定图案的触控电极135，不再需要去除触控电极板的材料，进而避免损坏薄膜封装12和柔性显示屏11。具体地，触控电极135的材料可以是Ag(银)、ITO(氧化铟锡)或IZO(氧化铟锌)等材料，较佳地，触控电极135的材料为透光的材料，以不影响用户观察显示屏的显示内容。当触控电极135的材料为非透光的材料时，触控电极135优选在垂直于柔性显示屏11的方向上与柔性显示屏11中的不透光结构重叠，其中不透光结构包括但不限于栅极线、源极线或发射电极线等。
在蒸镀形成触控电极135时，将触控电极135材料蒸发或升华，使触控电极135材料穿过金属掩膜的通孔并在下膜层121的表面析出，以形成具有预定图案的触控电极135。在触控电极135制备上膜层122，上膜层122可防止空气和水蒸汽等进入触控电极135，防止触控电极135被氧化。
下膜层121和上膜层122可以通过CVD(化学气相沉积)、PVD(物理气相沉积)、IJP(喷墨打印)、溅镀等方式形成。
具体地，请参阅图2，在某些实施方式中，上膜层122包括一层或多层子上膜层1221，子上膜层1221为无机膜或有机膜。下膜层121包括一层或多层子下膜层1211，子下膜层1211为无机膜或有机膜。
有机膜可以是纤维素衍生物类、聚砜类、聚酰胺类、聚酰亚胺类、聚酯类聚稀烃类、含硅聚合物、含氟聚合物等高分子聚合物膜。无机膜可以是金属膜、合金膜、陶瓷膜、高分子技术配合膜、分子筛复合膜、沸石膜、玻璃膜等无机材料膜。
可以理解，当子上膜层1221和子下膜层1211的层数较多时，薄膜封装12的水氧透过率较低，即，空气和水蒸汽不易进入到柔性显示屏11内，当然，子上膜层1221和子下膜层1211的层数可按照具体的柔性显示屏11的封装需求进行调整。在本发明实施例中，子下膜层1211包括三层，以保证下膜层121能对柔性显示屏11提供足够的保护，且从柔性显示屏11到触控电极135的方向依次为无机膜、有机膜、无机膜，无机膜与柔性显示屏11接触，无机膜与触控电极135接触，利用无机膜的稳定性较好，减少子下膜层1211与柔性显示屏11和触控电极135之间的相互影响。
请参阅图2、图4和图5，在某些实施方式中，显示屏组件10包括显示电路16，显示电路16与柔性显示屏11电连接，步骤S1包括以下子步骤：
S11：形成器件层111；
S12：在器件层111上形成发光层112；和
S13：在发光层112上形成阴极113，阴极113与显示电路16连接。
具体地，器件层111制备在柔性基板114上，柔性基板114可以防止空气和水蒸汽进入柔性显示屏11，器件层111包括柔性显示屏11的开关电路、阳极等器件，发光层112形成在器件层111和阴极113之间，发光层112在器件层111和阴极113之间的电场的作用下发出特定颜色的光。阴极113的材料为ITO或IZO等的透光导电材料，或阴极113为厚度非常薄的金属材料，发光层112和阴极113也可以通过蒸镀的方式制备。发光层112与显示屏组件10的显示区对应，显示电路16与显示屏组件10的非显示区对应，例如显示电路16与手机显示屏的黑边对应。薄膜封装12的下膜层121形成在阴极113上。
请参阅图2、图5和图6，在某些实施方式中，显示屏组件10包括显示电路16和触控电路18，显示电路16用于与柔性显示屏11电连接，触控电路18用于与触控电极135电连接，显示屏组件10的制备方法还包括步骤S6：在触控电路18和显示电路16之间形成阻隔层17。
阻隔层17使得触控电路18和显示电路16之间互相绝缘，避免触控电路18和显示电路16之间互相影响。具体地，显示电路16的延伸范围可以大于触控电路18的延伸范围，且阻隔层17的延伸范围介于显示电路16的延伸范围和触控电路18的延伸范围之间，也就是显示电路16、阻隔层17和触控电路18形成阶梯状，使得阴极113的一部分可以直接形成在在显示电路16上，显示电路16与阴极113连接可靠。阻隔层17可以通过CVD、PVD、IJP、溅镀等方式形成。
请再参阅图5，显示屏组件10还包括触控电路18，触控电路18与触控电极135电连接，在下膜层121上蒸镀形成触控电极135的同时将触控电极135与触控电路18电连接。
触控电路18与触控电极135电连接，触控电路18可用于检测触控电极135上电势的变化以检测用户是否触摸柔性显示屏11和用户按压柔性显示屏11的力度等。
请参阅图5和图7，在某些实施方式中，显示屏组件10的制备方法还包括步骤S7：在触控电路18上形成保护层19，保护层19的上表面与上膜层122的上表面在同一个平面内。
保护层19可用于保护触控电路18，防止触控电路18被空气或水蒸汽侵蚀。保护层19的上表面与上膜层122的上表面在同一个平面内，提高显示屏组件10的平整度，降低显示屏组件10的整体厚度。
请参阅图2、图8和图9，在某些实施方式中，触控电极135包括互相绝缘的第一电极 层131和第二电极层132，步骤S4包括以下子步骤：
S41：在上膜层122上蒸镀形成第一电极层131，第一电极层131包括间隔排列的多个第一电极条1311，多个第一电极条1311平行设置；
S42：在第一电极层131上形成绝缘层123；和
S43：在绝缘层123上蒸镀形成第二电极层132，第二电极层132包括间隔排列的多个第二电极条1321，多个第二电极条1321平行设置，每个第二电极条1321在第一电极层131的正投影与每个第一电极条1311相交。
由于多个第一电极条1311互相平行，则多个第一电极条1311之间不导通，通过对第一电极条1311施加电压，并实时检测第一电极条1311的电压，当用户触摸盖板15时，用户与第一电极条1311之间形成电场，且第一电极条1311的高频电流部分流入用户，使得检测得到的第一电极条1311的电压发生变化，进而获取用户在盖板15上的触摸位置的一个维度的信息，也就是定位与用户按压位置对应的第一电极条1311。同理，通过检测第二电极条1321的电压变化可获取用户在盖板15上的触摸位置的另一个维度的信息，也就是定位与用户按压位置对应的第二电极条1321。由于每个第二电极条1321在第一电极层131的正投影与每个第一电极条1311相交，故结合两个维度的信息，可定位用户在盖板15上的触摸位置。
具体地，相邻的两个第一电极条1311的间隔相等，相邻的两个第二电极条1321的间隔相等，以使触控传感器13在各个位置的灵敏度相同。在某些实施方式中，每个第二电极条1321在第一电极层131的正投影与每个第一电极条1311互相垂直，以便于对矩形或方形等柔性显示屏11的触控电极135的布置。或者每个第二电极条1321在第一电极层131的正投影与每个第一电极条1311之间的夹角为锐角，以便于对平行四边形、梯形、三角形等柔性显示屏11的触控电极135的布置。
在某些实施方式中，绝缘层123是通过CVD、PVD、IJP中的一种方式在第一电极层131上形成的。
请参阅图2、图10和图11，在某些实施方式中，触控电极135包括互相导通的第一电极133和第二电极134，步骤S4包括以下子步骤：
S44：在下膜层121上蒸镀形成第一电极133，第一电极133包括间隔设置的两个第一子电极1331；和
S45：在下膜层121上蒸镀形成第二电极134，第二电极134包括多个间隔设置的第二子电极1341，多个第二子电极1341间隔设置在两个第一子电极1331之间，每个第二子电极1341与一个第一子电极1331连接且与另一个第一子电极1331间隔设置。
可以以如图10所示的第一电极133和第二电极134为一个触控单元，在下膜层121上 制备多个触控单元。在使用中，一个第一子电极1331和与之连接的第二子电极1341相当于电容的一个极板(左边的梳状结构)，另一个第一子电极1331和与之连接的第二子电极1341相当于电容的另一个极板(右边的梳状结构)，两个极板不电连接，且彼此之间形成互电容，当用户触摸盖板15时，例如用户用手指触摸盖板15时，手指影响了两个极板之间的电容耦合，进而改变极板的电势，触控电路18通过定位被影响的电容耦合的位置以定位用户在盖板15上的触摸位置。
可以理解，在蒸镀前需要先在金属掩膜上开设与预设图案相同的通孔，第一电极133和第二电极134也可以一次性蒸镀在下膜层121上，然而，此时金属掩膜上的图案较为复杂，通孔的面积较大，而导致金属掩膜的强度较低且分布不均，金属掩膜在焊接时容易变形而不能得到预定的图案。将第一电极133和第二电极134分两次蒸镀在下膜层121上，能够提高制备触控电极135的良率。当然，步骤S44也可以在步骤S45之后实施，也就是先形成第二电极134后，再形成第一电极133。
当然，触控电极135的具体图案不限于上述的几种举例，其他的图案也可以通过蒸镀的方式形成在下膜层121上，在此不作限定。
