第二方面、本发明实施例提供了一种柔性触控显示面板的制备方法，所述制备方法包括，采用图案化工艺，在柔性显示基板上形成金属网格电极图案与条状桥接电极图案中的一者；形成彩膜层，包括间隔排列的多个彩色滤光块；以及形成在各所述彩色滤光块之间的遮光层；所述遮光层在所述柔性显示基板上的正投影覆盖在先形成的所述金属网格电极图案或所述条状桥接电极图案；在所述遮光层上形成所述金属网格电极图案与所述条状桥接电极图案中的另一者，所述遮光层在所述柔性显示基板上的正投影覆盖在后形成的 所述金属网格电极图案或所述条状桥接电极图案；其中，形成的所述金属网格电极图案包括，相互绝缘且交叉设置的多根第一电极与多根第二电极；形成的所述条状桥接电极图案包括，平行排列的多个条状桥接电极；形成的所述第一电极与所述第二电极中的一者与形成的所述条状桥接电极通过形成在所述遮光层上的过孔电性连接。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要指出的是，除非另有定义，本发明实施例中所使用的所有术语(包括技术和科学术语)具有与本发明所属领域的普通技术人员共同理解的相同含义。还应当理解，诸如在通常字典里定义的那些术语应当被解释为具有与它们在相关技术的上下文中的含义相一致的含义，而不应用理想化或极度形式化的意义来解释，除非这里明确地这样定义。
例如，本发明专利申请说明书以及权利要求书中所使用的术语“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，仅是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“横向”、“纵向”、“一侧”以及“另一侧”等指示的方位或位置关系的术语为基于附图所示的方位或位置关系，仅是为了便于说明本发明的技术方案的简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
如图1和图2所示，本发明实施例提供了一种柔性触控显示面板，该柔性触控显示面板包括，柔性显示基板1、设置在柔性显示基板1上方的彩膜层(Color Filter，简称为CF)；该彩膜层包括，间 隔排列的多个彩色滤光块2；以及设置在各彩色滤光块2之间的遮光层3；上述柔性触控显示面板还包括，位于遮光层3两侧的金属网格电极图案与条状桥接电极图案，遮光层3在前述柔性显示基板1上的正投影覆盖金属网格电极图案与条状桥接电极图案在前述柔性显示基板1上的正投影；其中，上述的金属网格电极图案包括，相互绝缘且交叉设置的多根第一电极41与多根第二电极42；上述的条状桥接电极图案包括，平行排列的多个条状桥接电极(Bridge)5；前述的第一电极41与第二电极42中的一者与条状桥接电极5通过设置在遮光层3上的过孔(Bridge Hole)30电性连接。
需要说明的是，第一、上述柔性显示基板1具体包括有，柔性衬底、设置在柔性衬底上的多个显示单元和覆盖显示单元的薄膜封装层(Thin Film Encapsulation，简称为TFE)；各颜色的彩色滤光块2与显示单元相对应。
其中，显示单元由有机电致发光显示器件(Organic Light-Emitting Display，简称为OLED器件)以及用于驱动OLED器件发光的TFT(Thin Film Transistor，薄膜晶体管)等结构构成，具体可沿用现有技术，本发明实施例对此不再赘述。
第二、在本发明实施例提供的上述柔性触控显示面板中，彩膜层中的彩色滤光块2的光透过率高于现有技术中贴合在显示面板显示面上的偏光片的光透过率，且设置在各彩色滤光块2之间的遮光层3可以遮挡柔性显示基板1中位于各显示单元之间的金属走线等光反射率较高的反光元件对于环境光的反射，因此上述彩膜层可以在具有抗反射功能的同时，保证上述柔性触控显示面板具有良好的显示亮度。并且，彩膜层的厚度通常小于现有技术中的偏光片的厚度，有利于对上述柔性触控显示面板进行弯折操作。
其中，上述图1和图2中仅以彩色滤光块2包括红色(Red，图中以字母R示意出)、绿色(Green，图中以字母G示意出)以及蓝色(Blue，图中以字母B示意出)为例进行示意，当然还可包括有黄色等其他颜色的彩色滤光块；并且，彩色滤光块2的排列方式不限于上图中所示意出的呈条状阵列排列，还可以呈马赛克形排列、品字形排列，具体可沿用现有技术，本发明实施例对此不再赘述。
第三、上述位于遮光层3两侧的金属网格电极图案与条状桥接电极图案，即指参考图1所示，当金属网格电极图案设置在遮光层3上方(即远离柔性显示基板1的一侧)时，条状桥接电极图案则设置在遮光层的下方(即遮光层3与柔性显示基板1之间)；反之，参考图2所示，指当金属网格电极图案设置在遮光层3下方时，条状桥接电极图案则设置在遮光层的上方。
其中遮光层3具体可以采用黑矩阵(Black Matrix，简称为BM)材料实现。
第四、在上述的金属网格电极图案中，由于相互绝缘且交叉设置的多根第一电极41与多根第二电极42均设置在遮光层3的同侧(即均设置在其上方或其下方)，故其中一个电极在与另一个电极的相互交叉处为断开的设计，以避免同层设置的两种电极发生电连接，影响触控信号。
由于上述的一个电极在与另一个电极的相互交叉处断开，故需要通过设置在下方或上方的条状桥接电极5借助遮光层3上的过孔30电性连接，通过遮光层3上叠构设计的过孔30搭桥以实现有断开处设计的该电极的电信号传输。
这里，第一电极41与第二电极42互为触控驱动电极(常缩写为Tx，即接收触控的驱动信号)与触控感应电极(常缩写Rx，即接收触控的感应信号)。
第五、金属网格电极图案分布可以是周期性或非周期性的排列，即相邻两根第一电极41与交叉设置的相邻两根第二电极42限定出的区域可包括有一个(即参考图1和图2所示)或多个显示单元。
基于此，通过本发明实施例提供的上述柔性触控显示面板，由于具有上述叠构设计的金属网格电极图案与条状桥接电极图案均由金属材料构成，利用金属具有的良好延展性的特性，可实现柔性触控显示面板的可折叠功能；并且，由于金属网格电极图案与条状桥接电极图案在柔性显示基板1上的正投影均被遮光层3在柔性显示基板1上的正投影所覆盖，利用遮光层3对金属图案的遮挡可有效降低这些金属走线被人眼察觉的程度，从而可在不影响正常显示的情况下实现触控功能。
此外，由于上述柔性触控显示面板的制备工艺对现有的量产工艺改动较小，可在无明显量产成本变化的基础上实现柔性触控显示产品的可折叠穿戴效果，进而达到提高产品价值的提升效果。
进一步的具体的，参考图1所示，上述遮光层3包括，多个第一部分(即遮光层3沿垂直于图示平面方向的纵向部分)和多个第二部分(即遮光层3沿图中自左至右方向的横向部分)，第一部分与第二部分相互交叉形成网格状的图案；第一电极41在柔性显示基板上的正投影被第一部分在柔性显示基板上的正投影所覆盖；第二电极42与条状桥接电极5一一对应，且第二电极42与条状桥接电极5在柔性显示基板上的正投影被第二部分在柔性显示基板上的正投影所覆盖；其中，每根第二电极42包括间隔开来的多个电极段420，相邻两个电极段420之间设置有一根第一电极41；每个电极段420与对应的条状桥接电极5通过过孔30电性连接。
进一步的具体的，参考图2所示，上述遮光层3包括，多个第一部分(即遮光层3沿图中自左至右方向的横向部分)和多个第二部分(即遮光层3沿垂直于图示平面方向的纵向部分)，第一部分与第二部分相互交叉形成网格状的图案；第一电极41与条状桥接电极5一一对应，且第一电极41与条状桥接电极5在柔性显示基板上的正投影被第一部分在柔性显示基板上的正投影所覆盖；第二电极42在柔性显示基板上的正投影被第二部分在柔性显示基板上的正投影所覆盖；其中，每根第一电极41包括间隔开来的多个电极段410，相邻两个电极段410之间设置有一根第二电极42；每个电极段410与对应的条状桥接电极5通过过孔30电性连接。
在上述基础上，由于上述柔性触控显示面板中具有抗反射功能的彩膜层，因此柔性显示基板1中的显示单元可以为发出单色白光OLED显示单元；当然，各显示单元也可以为发出红、绿、蓝等彩色颜色的OLED显示单元，各彩色滤光块的颜色与对应的各显示单元显示的颜色相同即可。
进一步的，本发明实施例还提供了一种上述柔性触控显示面板的制备方法，该制备方法包括，
步骤S1、采用图案化工艺，在柔性显示基板上形成金属网格电 极图案与条状桥接电极图案中的一者；
步骤S2、形成彩膜层，包括间隔排列的多个彩色滤光块；以及形成在各彩色滤光块之间的遮光层；遮光层在柔性显示基板上的正投影覆盖在先形成的金属网格电极图案或条状桥接电极图案；
步骤S3、在遮光层上形成金属网格电极图案与条状桥接电极图案中的另一者，遮光层在柔性显示基板上的正投影覆盖在后形成的金属网格电极图案或条状桥接电极图案；
其中，形成的金属网格电极图案包括，相互绝缘且交叉设置的多根第一电极与多根第二电极；形成的条状桥接电极图案包括，平行排列的多个条状桥接电极；形成的第一电极与第二电极中的一者与形成的条状桥接电极通过形成在遮光层上的过孔电性连接。
这里，上述的图案化工艺是对膜层进行处理以形成具有特定图案的工艺，典型的图案化工艺是应用一次掩模板，通过对光刻胶曝光、显影、刻蚀膜层、去除光刻胶的过程。
进一步的，形成上述步骤1中的柔性显示面板的步骤包括：
提供一柔性衬底；
依次在柔性衬底上形成多个显示单元和覆盖显示单元的薄膜封装层；
其中，后续步骤2形成的彩色滤光块与在先形成的显示单元相对应。
在上述基础上，本发明实施例还提供了一种显示装置，包括上述的柔性触控显示面板。上述显示装置具体可以是OLED显示装置，例如为显示器、电视、数码相框、手机、平板电脑、数码相框、导航仪以及具有显示屏的智能手环等具有任何显示功能的产品或者部件。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
