触摸屏种类繁多，比较主流的电容式触摸屏为玻璃电容式触摸屏和Film电容式触摸屏。GF1触摸屏是Film电容式触摸屏的一种，也称为单层多点触摸屏或者单面单层多点触摸屏，这种触摸屏的设计是在一层氧化铟锡(ITO)导电层上蚀刻出ITO线路，包括感应信号线和驱动信号线。由于ITO线路图案比较复杂，而ITO导电层本身空间有限，造成了ITO线路布局时线宽较窄，进而与外部软性线路板(Flexible Printed Circuit，简称FPC)连接的端子(pin)太多，导致触摸屏的触控精度较低，产品可靠性比较差，生产良率低。
发明内容

作为一种可选的实施方式，所述架桥导电线412为银胶导电线。
作为一种可选的实施方式，所述第二绝缘层50为整面覆盖在所述ITO导电层60上，或者所述第二绝缘层50为局部覆盖在所述氧化铟锡ITO导电层60上。

图1为本发明公开的单面双层多点触摸屏的整体结构示意图；
图2为本发明公开的导电层的透视图；
图3为本发明公开的导电层的局部放大图。
具体实施方式
下面将结合本发明的附图，对本发明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。
本发明提供了一种单面双层多点触摸屏，用于提高触摸屏的触控精度，以获得更高的产品良率。
请参阅图1～3，其中，图1为本发明公开的单面双层多点触摸屏的整体结构示意图；图2为本发明公开的导电层的透视图；图3为本发明公开的导电层的局部放大图。结合图1～3所示，本发明公开的单面双层多点触摸屏包括：自上而下依次设置的盖板10、粘胶层20和具备架桥功能的导电层；导电层包括自上而下依次设置的第一绝缘层30、银胶导电层40、第二绝缘层50和氧化铟锡ITO导电层60；
其中，ITO导电层60包括柔性透明基板611、镀印在柔性透明基板611上的ITO镀膜层612、以及在ITO镀膜层612上蚀刻得到的多个驱动电极613和与多个驱动电极613形成形状互补且相互隔离的感应电极614；
第二绝缘层50上设置有绝缘通孔511，银胶导电层40包括架桥导电线 412以及设置在银胶导电层40一端用于连接驱动电极613和感应电极614的金属导电线411，架桥导电线412用于通过第二绝缘层50上的绝缘通孔511连接相邻的驱动电极613。
可以看出，在本发明中，通过在柔性透明基板611一面镀膜，得到ITO镀膜层612，然后在一个ITO镀膜层612上蚀刻出感应电极613和驱动电极614。在ITO导电层60上先设置第二绝缘层50，提高ITO导电层60和银胶导电层40之间的绝缘效果，有助于提高触摸屏的良率；在第二绝缘层50中设置了绝缘通孔511，银胶导电层40中的架桥导电线412通过绝缘通孔511将ITO导电层60中的驱动电极613连接起来，同一列驱动电极613只需要通过一个端子即可连接外部FPC，从而减少连接端子，提高了走线的线宽，进而提高触摸屏的触控精度。在银胶导电层40上再设置第一绝缘层30，以提高银胶导电层的绝缘效果。
在本发明中，驱动电极613的形状为几何图形，如菱形、正方形、长方形等，感应电极614的形状为与驱动电极613的形状互补的几何图形。在本发明中以驱动电极613和感应电极614的形状为菱形为例进行说明，ITO导电层60的每一列中相邻的两个驱动电极613和每一行中相邻的两个感应电极614形成一个大菱形。驱动电极613与感应电极614之间未被蚀刻掉的部分形成ITO通道615。如图3所示，将该大菱形看作一个电极单元，在一个电极单元中，可以看出4个小菱形的交界处感应电极614是相连的，而同一列中的相邻两个驱动电极613被感应电极614隔离开。在一个电极单元中，若感应电极614和驱动电极613不是边界的电极，那么每一个感应电极614和每一个驱动电极613都会服务于两个电极单元。
作为一种可选的实施方式，在ITO导电层60上设置第二绝缘层50，具体可以是整个ITO导电层60上设置第二绝缘层50；或者是在ITO导电层60的中的每一个电极单元的2个驱动电极613和2个感应电极614的交界处上设置第二绝缘层50。
可以理解，在本发明中，在进行第一绝缘层30或者第二绝缘层40压膜时，可以采用90℃-130℃的温度。
其中，感应电极614和驱动电极613是蚀刻ITO镀膜层612得到的，未 被蚀刻掉的地方为ITO通道615，感应电极614和驱动电极613被ITO通道615隔离开。作为一种可选的实施方式，ITO通道615的宽度大于或等于9μm且小于或等于11μm；该ITO通道615的间距大于或等于4μm且小于或等于6μm。其中，ITO通道615的宽度是指ITO通道615的宽度，ITO通道615的间距是指ITO通道615之间的距离。
在第二绝缘层50上设置有绝缘通孔511，具体地该绝缘通孔511用于利用架桥导电线412将相邻驱动电极613连接起来，因此，可以在驱动电极613对应的第二绝缘层50的位置上设置绝缘通孔511，如图3所示，在每一个电极单元的2个驱动电极613对应的第二绝缘层50上分别设置了一个绝缘通孔511，从而银胶导电层40中的架桥导电线412通过两个绝缘通孔511将两个驱动电极613连接起来，依次类推，每一个电极单元的2个驱动电极613被连接后，也就是将整一列的驱动电极613连接起来了，从而一列驱动电极613只需要通过一个端子即可连接到FPC上。同时，由于同一行中感应电极614是相连的，因此，每一行感应电极614也只需要一个端子即可连接到FPC上。可以看出，该发明中减少了端子的数量，提高了走线宽度，从而提高触摸屏的触控精度，提高触摸屏的良率。
作为一种可选的实施方式，架桥导电线412的数量设置为2条，每一条架桥导电线412的线宽小于或等于5μm，2条架桥导电线412之间的间距小于或等于5μm。
作为一种可选的实施方式，该架桥导电线412可以是银胶导电线。
作为一种可选的实施方式，该架桥导电线412可以是通过黄光蚀刻技术蚀刻得到，用于连接2个驱动电极613；或者是通过丝版印刷技术印刷得到，用于连接2个驱动电极613。
作为一种可选的实施方式，盖板10的材质为化学强化玻璃或者塑料。
作为一种可选的实施方式，柔性透明基板611的材质为钢化玻璃或者有机玻璃或者透明塑料。然后在柔性透明基板611上镀印上ITO镀膜层612，柔性透明基板611透明性好，而ITO也具有良好的导电性和透明性，可以切断对人体有害的电子辐射、紫外线及远红外线。因此，ITO镀印在柔性透明基板611后，可以增强导电性和透明性，同时切断对人体有害的电子辐射。
作为一种可选的实施方式，驱动电极613和感应电极614可以通过激光蚀刻得到。
作为一种可选的实施方式，柔性透明基板611为矩形结构，且该矩形结构的四个顶点为圆弧形，即采用圆弧过渡。那么，ITO导电层也为矩形结构，相应地，银胶导电层40和盖板等均为矩形结构，且矩形结构的四个顶点均为圆弧过渡。矩形结构在生产中便于加工制作，适合大部分终端。圆弧过渡能够帮助消除ITO导电层的应力突变的点，消除了再加工工程中的应力集中，提高产品使用寿命。
本发明提供的单面双层多点触摸屏可以广泛使用在带有触摸屏的终端，或者带有触摸屏的平板电脑，或者触摸屏手机等产品上。
以上对本发明所提供的一种单面双层多点触摸屏进行了详细介绍，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
