Description

基于聚酰亚胺的纳米银触控模组及其制作方法、电子设备
本申请要求于2016年7月18日提交中国专利局、申请号为201610569855.5、发明名称为“基于聚酰亚胺的纳米银触控模组及其制作方法、电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示及触控技术领域，更具体地说，涉及一种基于聚酰亚胺的纳米银触控模组及其制作方法、电子设备。
背景技术
触控技术已经广泛应用于各种触控显示屏当中，现有技术中主流的触控模组主要包括：聚酰亚胺膜层以及位于所述聚酰亚胺膜层表面的氧化铟锡(Indium Tin Oxide，ITO)架桥，所述ITO架桥包括沿第一方向排布的多个第一ITO电极和沿第二方向排布的多个第二ITO电极，所述多个第一ITO电极和多个第二ITO电极彼此绝缘。所述ITO架桥用于将操作体的触摸位置转换为电信号，以实现操作体触摸位置的识别。
但是由于ITO需要通过采用较为昂贵的磁控溅射设备制备，提升了所述触控模组的制备成本。
因此，亟需一种制备成本较低的触控模组。
发明内容
为解决上述技术问题，本发明提供了一种基于聚酰亚胺的纳米银触控模组及其制作方法、电子设备，以实现降低所述触控模组的制备成本的目的。
为实现上述技术目的，本发明实施例提供了如下技术方案：

在所述第一纳米银层背离所述基板表面涂布聚酰亚胺膜层；
在所述聚酰亚胺膜层背离所述第一纳米银层表面制备第二纳米银层；
对所述第二纳米银层进行处理获得多个第二电极，所述多个第二电极沿第二方向排布；
将所述第一纳米银层与所述基板剥离；
将所述多个第二电极与盖板贴合；
对所述第一纳米银层进行处理获得多个第一电极，所述多个第一电极沿第一方向排布，所述第一方向不与第二方向平行，所述多个第一电极和多个第二电极构成纳米银触控电极。
优选的，所述第一方向与所述第二方向垂直。

聚酰亚胺膜层；
设置于所述聚酰亚胺膜层表面的纳米银触控电极，所述纳米银触控电极包括位于所述聚酰亚胺膜层表面的沿第一方向排布的多个第一电极，以及位于所述聚酰亚胺膜层背离所述多个第一电极一侧表面的沿第二方向排布的多个第二电极；所述第一方向不与所述第二方向平行；
位于所述第二电极背离所述聚酰亚胺膜层表面的盖板。
优选的，所述第一方向与所述第二方向垂直。
优选的，所述盖板为曲面盖板。
优选的，所述盖板为钢化玻璃盖板或亚克力盖板或蓝宝石玻璃盖板。

优选的，所述显示模组为有机发光二极管显示模组或液晶显示模组。
一种电子设备，包括至少一个如上述任一实施例所述的触控模组。
从上述技术方案可以看出，本发明实施例提供了一种基于聚酰亚胺的纳米银触控模组及其制作方法、电子设备；其中，利用所述基于聚酰亚胺的纳米银触控模组的制作方法制备的所述触控模组包括聚酰亚胺膜层、设置于所述聚酰 亚胺膜层表面的纳米银触控电极以及位于所述第二电极背离所述聚酰亚胺膜层表面的盖板；所述纳米银触控电极可以通过涂布的方式设置于所述聚酰亚胺膜层表面，而不必采用昂贵的磁控溅射设备，从而降低了所述触控模组的成本。并且这种结构的触控模组由于不存在架桥结构和触控电极位于所述聚酰亚胺膜层上的原因，不会出现架桥可视的问题，并且降低了盖板碎裂后无法触控的可能。
另外，由于所述纳米银触控电极的材质为纳米金属材质，其自身的延展性要远远由于ITO材质，当所述纳米银触控电极应用于曲面结构的触控显示屏中时，纳米金属材质良好的延展性会使得所述纳米银触控电极能够与所述触控显示屏的盖板良好贴合，从而使得应用所述触控模组的触控显示屏的良品率更高，并且触控灵敏度更高。
进一步的，所述聚酰亚胺薄膜具有优异的高温耐热安定性、高机械强度、极佳的抗腐蚀特性、极佳的介电性能、厚度较薄以及耐弯折的优点，因此利用所述基于聚酰亚胺的纳米银触控模组的制作方法制备的所述触控模组的厚度较薄，且稳定性较高。

另外，所述纳米银材质具有优良的导电和导热性，并且在不同环境下都具有较高的稳定性，进一步的所述纳米银材质可以通过简单廉价的化学还原法和水热法合成，因此利用纳米银材质制备所述触控模组的成本较低。
在上述实施例的基础上，在本申请的一个实施例中，所述盖板300为曲面盖板。
在本申请的一个实施例中，所述盖板300的可以为钢化玻璃盖板或蓝宝石盖板或亚克力盖板。在本申请的其他实施例中，所述盖板300还可以为柔性薄膜材料盖板。本申请对所述盖板300的具体种类并不做限定，具体视实际情况而定。
相应的，本申请实施例还提供了一种触控显示屏，包括：
显示模组；
位于所述显示模组表面的触控模组，所述触控模组为上述任一实施例所述的触控模组。
所述显示模组可以为液晶显示模组或有机发光二极管显示模组。本申请对所述显示模组的具体种类并不做限定，具体视实际情况而定。
相应的，本申请实施例还提供了一种电子设备，包括至少一个如上述任一实施例所述的触控模组。
综上所述，本申请实施例提供了一种基于聚酰亚胺的纳米银触控模组及其制作方法、电子设备；其中，利用所述基于聚酰亚胺的纳米银触控模组的制作方法制备的所述触控模组包括聚酰亚胺膜层100、设置于所述聚酰亚胺膜层100表面的纳米银触控电极200以及位于所述第二电极201背离所述聚酰亚胺膜层100表面的盖板300；所述纳米银触控电极200可以通过涂布的方式设置于所述聚酰亚胺膜层100表面，而不必采用昂贵的磁控溅射设备，从而降低了所述触控模组的成本。并且这种结构的触控模组由于不存在架桥结构和触控电极位于所述聚酰亚胺膜层100上的原因，不会出现架桥可视的问题，并且降低了所述盖板300碎裂后无法触控的可能。
另外，由于所述纳米银触控电极200的材质为纳米金属材质，其自身的延展性要远远由于ITO材质，当所述纳米银触控电极200应用于曲面结构的触控 显示屏中时，纳米金属材质良好的延展性会使得所述纳米银触控电极200能够与所述触控显示屏的盖板300良好贴合，从而使得应用所述触控模组的触控显示屏的良品率更高，并且触控灵敏度更高。
进一步的，所述聚酰亚胺薄膜具有优异的高温耐热安定性、高机械强度、极佳的抗腐蚀特性、极佳的介电性能、厚度较薄以及耐弯折的优点，因此利用所述基于聚酰亚胺的纳米银触控模组的制作方法制备的所述触控模组的厚度较薄，且稳定性较高。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
