针对现有柔性显示装置厚度较大的技术问题，本申请可以缓解这个问题。
在一种实施例中，如图2所示，本实施例提供的偏光触控构件包括：
基板10；
偏光层20，形成于所述基板的第一表面上；
触控层30，形成于所述基板的第二表面上；
第一保护层40，设置在所述偏光层远离所述基板的表面上；
第二保护层50，设置在所述触控层远离所述基板的表面上。
本实施例提供了一种偏光触控构件，其包括：基板；偏光层，形成于所述基板的第一表面上；触控层，形成于所述基板的第二表面上；第一保护层，设置在所述偏光层远离所述基板的表面上；第二保护层，设置在所述触控层远离所述基板的表面上。本申请通过将触控层与偏光层集成为一体作为偏光触控构件，这样触控层与偏光层之间就不需要额外的胶层贴合，使的柔性显示装置整体厚度降低，更加轻薄。
在一种实施例中，所述基板10的材料可以是COP（Cyclo Olefin Polymers，环烯烃共聚物），PET（Polyethylene  terephthalate，涤纶树脂）等，以保证所述偏光触控构件具有较好的弯折特性。
在一种实施例中，如图2所示，所述偏光层20形成于所述基板10的第一表面上，包括位相补差膜201和偏光功能膜202，所述位相补差膜201形成于所述基板10的第一表面上。
在一种实施例中，如图2所示，所述位相补差膜201以所述基板10为基底，通过涂布工艺直接形成于所述基板10上，即所述位相补差膜201与所述基板10之间不需要涂覆胶层连接，而是所述位相补差膜201直接制备在所述基板10上。具体地，所述位相补差膜201为四分之一波长膜。
所述偏光功能膜202在所述偏光层20中起到主要偏光作用，其决定了所述偏光层20的偏光性能、透过率，同时所述偏光功能膜202也是影响所述偏光层20色调和光学耐久性的主要部分。
在一种实施例中，如图2所示，所述偏光层20还包括粘合层203，所述粘合层203设置在所述位相补差膜201远离所述基板10的一侧表面上，在本实施例中，所述粘合层203材质为压敏胶，由于压敏胶具有低弹性模量和高弯曲的特性，可以用来支撑与保护所述偏光功能膜202。
在一种实施例中，所述偏光功能膜202为聚乙烯醇膜。所述聚乙烯醇膜通过光配向技术光排列双吸收染料分子，取得很高的D值，再将染料分子涂布在所述粘合层203上，形成聚乙烯醇膜，可选的，所述聚乙烯醇膜的厚度小于2微米。由于所述偏光功能膜202是由涂布方式制备，与现有的聚乙烯醇拉伸制成的薄膜层相比厚度明显降低。
由于聚乙烯醇材料易吸水、褪色，因此需要在所述偏光功能膜202远离所述粘合层203的一侧表面上，设置光学均匀性和透明性良好的材料来隔绝水分和空气，保护偏光功能膜202，防止偏光功能膜202因吸水、褪色而丧失偏光性能。
因此，在一种实施例中，如图2所示，所述偏光层20还包括隔绝层204，所述隔绝层204位于所述偏光功能膜202远离所述粘合层203的一侧表面上，用于隔绝水分和空气，保护所述偏光功能膜202。在本实施例中，所述隔绝层204为材质为三醋酸纤维素。
现有技术的偏光功能膜是采用聚乙烯醇拉伸制成薄膜，再粘合至相位补差膜上，因此需要先在偏光功能膜的上下表面各制备一层隔绝层，以隔绝水分和空气，再进行粘合。
相比于现有技术来说，本申请实施例提供的偏光触控构件，由于所述偏光功能膜202是由涂布方式制备，只需在涂布后的上表面制备隔绝层，即减少了所述偏光功能膜202与所述位相补差膜201之间的一层隔绝层；同时，由涂布方式制备的聚乙烯醇薄膜层相比拉伸制成的聚乙烯醇薄膜层，厚度也明显降低，从而实现所述偏光触控构件的整体减薄。
在一种实施例中，如图2所示，所述触控层30形成于所述基板10的第二表面上，所述触控层30的具体结构请参照图3a和图3b。

在一种实施例中，所述驱动电极321和所述感应电极322同层设置，相邻两个所述感应电极322相连，并且所述感应电极322与所述驱动电极321之间设有断口，以使得在所述驱动电极321与所述感应电极322之间形成感应电容。相邻两个驱动电极321通过与感应电极322绝缘的导电桥323作为架桥相连，以互电容式来实现触控功能。
所述驱动电极321通过驱动电极走线3211连接至所述连接区31，所述感应电极322通过感应电极走线3221连接至所述连接区31，并通过所述连接区31内的所述连接端子310传递信号。

在本申请中，所述偏光层20与所述触控层30均直接制备在所述基板10上，相对于现有技术，所述偏光层20与所述基板10之间不需要粘合层，即减少了一层粘合层的厚度；由于所述位相补差膜201是由涂布方式制备，因此减少了所述位相补差膜201与所述基板10之间的一层粘合层；由于所述偏光功能膜202是由涂布方式制备，只需在涂布后的上表面制备隔绝层，因此减少了所述偏光功能膜202与所述位相补差膜201之间的一层隔绝层；同时，由涂布方式制备的聚乙烯醇薄膜层相比拉伸制成的聚乙烯醇薄膜层，厚度也明显降低。通过以上方式，相对现有技术，减少了三层粘合层和一层隔绝层的厚度，且偏光功能膜的厚度也降低，从而实现所述偏光触控构件的整体减薄。

在一种实施例中，如图4所示，所述柔性显示面板41与所述偏光触控构件42之间通过第一胶层44粘合，所述偏光触控构件42与所述保护盖板43之间通过第二胶层45粘合。在本申请实施例中，所述第一胶层44和所述第二胶层45为OCA（Optically Clear Adhesive，将光学亚克力胶做成无基材，然后在上下底层，再各贴合一层离型薄膜，是一种无基体材料的双面贴合胶带）光学胶。
在一种实施例中，如图4所示，所述柔性显示装置还包括柔性电路板46，所述柔性电路板46包括驱动芯片（图未示出），所述驱动芯片与所述偏光触控构件42电连接。

在一种实施例中，所述位相补差膜4221以所述基板421为基底，通过涂布工艺直接形成于所述基板421上，即所述位相补差膜4221与所述基板421之间不需要涂覆胶层连接，而是所述位相补差膜4221直接制备在所述基板421上。具体地，所述位相补差膜4221为四分之一波长膜。
所述偏光功能膜4222在所述偏光层422中起到主要偏光作用，其决定了所述偏光层422的偏光性能、透过率，同时所述偏光功能膜4222也是影响所述偏光层422色调和光学耐久性的主要部分。
所述偏光层422还包括粘合层4223，所述粘合层4223设置在所述位相补差膜4221远离所述基板421的一侧表面上，在本实施例中，所述粘合层4223材质为压敏胶，由于压敏胶具有低弹性模量和高弯曲的特性，可以用来支撑与保护所述偏光功能膜4222。
在一种实施例中，所述偏光功能膜4222为聚乙烯醇膜。所述聚乙烯醇膜通过光配向技术光排列双吸收染料分子，取得很高的D值，再将染料分子涂布在所述粘合层4223上，形成聚乙烯醇膜，可选的，所述聚乙烯醇膜的厚度小于2微米。由于所述偏光功能膜4222是由涂布方式制备，与现有的聚乙烯醇拉伸制成的薄膜层相比厚度明显降低。
由于聚乙烯醇材料易吸水、褪色，因此需要在所述偏光功能膜4222远离所述粘合层4223的一侧表面上，设置光学均匀性和透明性良好的材料来隔绝水分和空气，保护偏光功能膜4222，防止偏光功能膜4222因吸水、褪色而丧失偏光性能。

现有技术的偏光功能膜是采用聚乙烯醇拉伸制成薄膜，再粘合至相位补差膜上，因此需要先在偏光功能膜的上下表面各制备一层隔绝层，以隔绝水分和空气，再进行粘合。
相比于现有技术来说，本申请实施例提供的偏光触控构件，由于所述偏光功能膜4222是由涂布方式制备，只需在涂布后的上表面制备隔绝层，即减少了所述偏光功能膜4222与所述位相补差膜4221之间的一层隔绝层；同时，由涂布方式制备的聚乙烯醇薄膜层相比拉伸制成的聚乙烯醇薄膜层，厚度也明显降低，从而实现所述偏光触控构件的整体减薄。
