具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下文的公开提供了许多不同的实施例或例子用来实现本申请的不同结构。为了简化本申请的公开，下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申请。此外，本申请可以在不同例子中重复参考数字和/或字母。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例和/或设置之间的关系。此外，本申请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可应用于性和/或其他材料的使用。
相关技术中的柔性触控显示模组，采用柔性硬化盖板和偏光片，由于偏光片由PVA(聚 乙烯醇)薄膜、TAC(三醋酸纤维素)薄膜等多层薄膜组成，使得柔性触控显示模组整体厚度偏厚，两种结构堆叠总厚度为300μm以上，使得柔性触控显示模组的弯折性能受到极大的限制，而且，相关技术中的柔性触控显示模组在信赖性测试过程，容易出现吸收轴方向的裂纹。此外，相关技术中的柔性触控显示模组，在户外环境光使用场景下，用户会因为佩戴太阳眼镜发生某一角度严重偏暗，看不清楚。为了至少解决上述技术问题之一，本申请提出了一种柔性触控显示模组100和具有其的触控显示装置1000。
下面，参照附图，描述根据本申请第一方面实施例的柔性触控显示模组100。
如图1所示，柔性触控显示模组100包括：柔性显示面板1、柔性盖板2、线偏光层3、第一位相差板4以及第二位相差板5，柔性盖板2设于柔性显示面板1的显示侧，线偏光层3设于柔性显示面板1和柔性盖板2之间，第一位相差板4设于线偏光层3和柔性盖板2之间，第二位相差板5设于线偏光层3和柔性显示面板1之间。也就是说，柔性显示面板1、第二位相差板5、线偏光层3、第一位相差板4、柔性盖板2，沿着从非显示侧到显示侧的方向顺次排列。
在本申请的实施例中，“线偏光层3”指的是高度取向的高聚物膜，如以聚乙烯醇(PVC)为基材，吸附上具有二相色性的染料而制成，具有线偏振功能。由此，本申请通过将线偏光层3与柔性盖板2组合，取代相关技术中柔性硬化盖板和偏光片的组合，可以降低柔性触控显示模组100的厚度，有利于实现柔性触控显示模组100的柔性弯折。
集成
在本申请的实施例中，线偏光层3的吸收轴角度为90°，需要说明的是，对于长方形的柔性触控显示模组100来说，短边的延伸方向平行于折叠线的延伸方向，将折叠线的延伸方向定义为0°方向，这样，当线偏光层3的吸收轴角度为90°时，则说明线偏光层3的吸收轴的延伸方向垂直于折叠线的延伸方向，或者说，线偏光层3的吸收轴的延伸方向平行于柔性触控显示模组100的长边方向。由此，可以使得柔性触控显示模组100具有更强的抗拉伸性能，改善或者避免柔性触控显示模组100在弯折过程中出现吸收轴方向裂纹的问题，即具有较强的机械弯折特性。
例如图6所示，展现了线偏光层3为PVA膜时，吸收轴角度分别为0°、45°、90°时的应力对比图，从图中可以看出，当线偏光层3的吸收轴角度为90°时，柔性触控显示模组100具有更强的抗拉伸性能。并且，通过将线偏光层3的吸收轴角度设置为90°，有利于线偏光层3的剪裁，在同样尺寸的线偏母膜上可以裁剪出更多数量的线偏光层3，从而可以提高柔性触控显示模组100的材料利用率，节约材料成本，减少工艺制程。
在本申请的实施例中，如图1所示，第一位相差板4包括第一位相差膜41，第一位相差膜41为具有四分之一波长位相延迟的液晶层，即光波通过第一位相差膜41产生四分之一波长的位相差，第一位相差膜41在与柔性显示面板1平行的平面具有长轴和短轴，当线偏光层3的吸收轴角度为90°时，第一位相差膜41的短轴延伸方向与线偏光层3的吸收轴之间的夹角为45°。由此，柔性触控显示模组100可以具有sunglassfree功能(简称无墨镜功能)，即在户外环境光使用场景下，不会因为戴太阳眼镜发生某一角度严重偏暗，而看不清楚的现象。
综上，根据本申请实施例的柔性触控显示模组100，厚度薄，柔性好，降低材料成本，方便工艺加工，具有较强的有更强的抗拉性能，同时具有sunglassfree功能。
在本申请的一些实施例中，柔性盖板2为单层或多层结构。例如，柔性盖板2的材料包括聚酰亚胺、聚对苯二甲酸乙二醇酯、聚碳酸酯、聚芳酯、聚醚砜、聚萘二甲酸乙二醇酯、纤维强化塑料、超薄玻璃、以及聚甲基丙烯酸十二酯中的一种或两种以上的组合。由此，可以具有较好的柔性和保护性能。当然本申请不限于此，在本申请的其他实施例中，柔性盖板2还可以采用其他材质制成，这里不作赘述。可以理解的是，为了保证显示效果，柔性盖板2是透明的。
在本申请的一些实施例中，线偏光层3包括碘系偏光膜、染料系偏光膜中的至少一层，其中，碘系偏光膜例如可以为：以聚乙烯醇(PVC)为基材，吸附上具有碘的染料而制成。由此，线偏振性能较好，且保证柔性触控显示模组100的柔性较好。当然本申请不限于此，在本申请的其他实施例中，线偏光层3还可以采用其他材质制成，这里不作赘述。
在本申请的一些实施例中，如图2所示，第一位相差板4还包括：第二位相差膜42，第二位相差膜42为具有二分之一波长位相延迟的液晶层，第二位相差膜42在与柔性显示面板1平行的平面具有长轴和短轴，第二位相差膜42位于第一位相差膜41与线偏光层3之间。也就是说，在第一位相差膜41和线偏光层3之间设置第二位相差膜42，且光波通过第二位相差膜42产生二分之一波长的位相差。由此，对于从非显示侧向显示侧射出的光，具有较好的防反射功能，且能够保证柔性触控显示模组100的柔性较好。
在本申请的一些实施例中，如图2所示，第二位相差板5包括：第三位相差膜51，第三位相差膜51为具有四分之一波长位相延迟的液晶层，第三位相差膜51在与柔性显示面板1平行的平面具有长轴和短轴。也就是说，在柔性显示面板1和线偏光层3之间设置第三位相差膜51，且光波通过第三位相差膜51产生四分之一波长的位相差。由此，可以实现从线偏到圆偏的转化，且对于从显示侧向非显示侧射入的光，具有一定的防反射功能，且 能够保证柔性触控显示模组100的柔性较好。
在本申请的一些实施例中，如图3所示，第二位相差板5包括：第四位相差膜52，第四位相差膜52为具有二分之一波长位相延迟的液晶层，第四位相差膜52在与柔性显示面板1平行的平面具有长轴和短轴，第四位相差膜52位于第三位相差膜51与线偏光层3之间。也就是说，在第三位相差膜51和线偏光层3之间设置第四位相差膜52，且光波通过第四位相差膜52产生二分之一波长的位相差。由此，对于从显示侧向非显示侧射入的光，可以具有更好的防反射功能，且能够保证柔性触控显示模组100的柔性较好。
在本申请的一些实施例中，第四位相差膜52的短轴延伸方向与线偏光层3的吸收轴之间的夹角为a1，a1＝15°±5°，第三位相差膜51的短轴延伸方向与线偏光层3的吸收轴之间的夹角为a2，a2＝2a1+45°。也就是说，线偏光层3的吸收轴方向与第四位相差膜52的短轴方向呈一特定的锐角a1，线偏光层3的吸收轴方向与第三位相差膜51的短轴方向夹角为a2，10°≤a1≤20°，a2＝2a1+45°。由此，对于从显示侧向非显示侧射入的光，可以具有更好的防反射功能。
在本申请的一些实施例中，第一位相差板4与柔性盖板2粘接。例如采用图1中所示的第一胶层61粘接，即第一位相差板4与柔性盖板2之间仅具有第一胶层61，而不具有其他膜层，从而有效地避免折弯过程中发生开裂等问题，保证连接可靠性，提高柔性触控显示模组100的柔性使用效果。例如第一胶层61可以为压敏胶等。
在本申请的一些实施例中，第一位相差板4与线偏光层3粘接。例如采用图1中所示的第二胶层62粘接，即第一位相差板4与线偏光层3之间仅具有第二胶层62，而不具有其他膜层，从而有效地避免折弯过程中发生开裂等问题，保证连接可靠性，提高柔性触控显示模组100的柔性使用效果。例如第二胶层62可以为纳米胶等。
在本申请的一些实施例中，第二位相差板5与线偏光层3粘接。例如采用图1中所示的第三胶层63粘接，即第二位相差板5与线偏光层3之间仅具有第三胶层63，而不具有其他膜层，从而有效地避免折弯过程中发生开裂等问题，保证连接可靠性，提高柔性触控显示模组100的柔性使用效果。例如第三胶层63可以为纳米胶等。
在本申请的一些实施例中，第二位相差板5与柔性显示面板1粘接。例如采用图1中所示的第四胶层64粘接，即第二位相差板5与柔性显示面板1之间仅具有第四胶层64，而不具有其他膜层，从而有效地避免折弯过程中发生开裂等问题，保证连接可靠性，提高柔性触控显示模组100的柔性使用效果。例如第四胶层64可以为压敏胶等。
相关技术中的柔性触控显示模组，在加工过程中，需要加入柔性硬化盖板与偏光片的贴 合工艺，使得模组工艺更加复杂化，产品的稳定性以及良率较低。而根据本申请实施例的柔性触控膜组，不需要使用偏光片，采用上述粘接技术就可以简单将线偏光层3粘贴至所需位置，实现模组制成，从而降低了加工难度，提高了产品的稳定性和生产良率。
更具体地说，在本申请的一些实施例中，柔性盖板2、第一胶层61、第一位相差板4、第二胶层62、线偏光层3、第三胶层63、第二位相差板5和第四胶层64可以构成一个集成模组，整体与柔性显示面板1粘接，从而提高了生产效率。
当然，本申请不限于此，还可以采用喷涂等工艺代替上述粘接的连接方式，这里不作赘述。
