此外，在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上，“多条”的含义是两条或两条以上。
下面就结合附图对本发明的各个优选实施方式进行详细的说明。

下面以图2为例具体说明一个实施方式中的电容感应单元和电磁感应单元的配置关系的优选方式。图2是根据本发明的一个实施方式的电磁电容触摸屏的总体结构的平面图。如图2所示，多个电容感应单元120a纵横排列，多个电磁感应单元130a纵横交错。
总的来说，优选在横向上排列的相邻两行电容感应单元之间具有至少两条横向的电磁感应线，至少两条横向的电磁感应线中的电流方向相反。优选，在纵向上排列的相邻两列电容感应单元之间具有至少两条纵向的电磁感应线，至少两条纵向的电磁感应线中的电流方向相反。优选，至少两条横向的电磁感应线和至少两条纵向的 电磁感应线中的一方在二者绝缘交叉的位置通过架桥结构连接。优选，至少两条横向的电磁感应线构成一组横向的电磁感应线，至少两条纵向的电磁感应线构成一组纵向的电磁感应线，多组横向的电磁感应线和多组纵向的电磁感应线纵横交错。优选，在相邻的两组横向的电磁感应线和相邻的两组纵向的电磁感应线所围绕的区域内，设置至少一个电容感应单元。优选，设置于相邻的所述区域内的电容感应单元之间通过架桥结构连接。优选，电容感应单元包括互容式电容感应单元，其包括至少一个驱动电极和至少一个感应电极。在互容式电容感应单元包括两个以上驱动电极和两个以上感应电极的情况下，优选驱动电极和感应电极中的一方通过架桥结构连接。优选，相邻的两个电容感应单元的驱动电极通过架桥结构连接。优选，相邻的两个电容感应单元的感应电极通过架桥结构连接。

如图3所示，互容式电容感应单元包括2个驱动电极310和2个感应电极320。在互容式电容感应单元的驱动电极和感应电极位于同一层的情况下，优选，将互容式电容感应单元的驱动电极和感应电极与电磁感应单元的电磁感应线设置在同一层。另外，在互容式电容感应单元的驱动电极和感应电极位于不同层的情况下，可以将互容式电容感应单元的驱动电极与电磁感应单元的电磁感应线设置在同一层，也可以将互容式电容感应单元的感应电极与电磁感应单元的电磁感应线设置在同一层。
2个驱动电极310通过位于同一层的导线连接，2个感应电极 320通过架桥结构350连接。这里，虽然图示了2个感应电极320通过架桥结构350连接，但是也可以是2个驱动电极310通过架桥结构连接。另外，虽然图示了2个驱动电极和2个感应电极，但是驱动电极和感应电极的数量和配置关系可以根据需要进行设定。
在互容式电容感应单元的周边设置了相互垂直的两个方向的电磁感应线，即两条纵向的电磁感应线340和两条横向的电磁感应线330。这里，虽然图示了两条纵向的电磁感应线340和两条横向的电磁感应线330，但是纵向的电磁感应线340和横向的电磁感应线330的条数可以根据需要进行设定。

另外，如图2所示，电磁感应线纵横交错，在相邻的两列电容感应单元之间设置两条电磁感应线，在相邻的两行电容感应单元之间设置两条电磁感应线。换句话说，在纵横交错的电磁感应线所围绕的每个区域内，设置电容感应单元。
本实施方式的电磁电容触摸屏，通过如上纵横交错设置电磁感应线，并纵横排列电容感应单元，即在每两个电容感应单元之间设置一对电磁感应线，在每两对电磁感应线之间设置电容感应单元，从而可以在电磁电容触摸屏的每个位置通过电容感应单元实现手指触摸功能，并且可以在电磁电容触摸屏的每个位置通过电磁感应线能实现笔触摸功能。
下面参照图6和7对架桥结构进行详细说明。可以理解，图6和7仅仅是举例说明一种优选的架桥结构。
图6是根据本发明的一个实施方式的电磁电容触摸屏的内部具有架桥结构的电容模块的示意图。图7是根据本发明的一个实施方式的电磁电容触摸屏的内部具有架桥结构的电磁模块的示意图。
如图6所示，在内部具有架桥结构的电容模块包括：电容电极层630；在电容电极层630上的绝缘层620；以及在绝缘层620上的架桥电极层610。
如图7所示，在内部具有架桥结构的电磁模块包括：电磁电极层730；在电磁电极层730上的绝缘层720；以及在绝缘层720上的架桥电极层710。
在此情况下，优选，将电容电极层630和电磁电极层730设置在同一层，将绝缘层620和绝缘层720设置在同一层，并将架桥电极层610和架桥电极层710设置在同一层。另外，优选，绝缘层620 和绝缘层720由同一层构成。

本实施方式的电磁电容触摸屏，通过架桥结构，能够以简单的结构实现手笔双触控功能，并且能够降低制造成本。另外，一个实施方式的电磁电容触摸屏，通过互容式电容感应电压来实现电容触控功能，能够发挥互容式电容触摸屏的优势。
下面简单说明一个实施方式的电磁电容触摸屏的工作原理。
基本工作原理如下所述：当采用手指触摸时，采用电容模块识别位置信息，手指触摸时造成的互电容变化导致接受信号发生变化，通过驱动电极给出波形信号，通过感应电极接受波形信号，根据波形信号差异识别位置信息；当采用电磁笔操作时，利用电磁笔操作过程中与电磁模块中电磁感应线发生感应，由产生的磁通量变化来运算出触控位置点。
本实施方式的电磁电容触摸屏，通过将电容模块和电磁模块设置在显示模块的同一层，与将电容模块和电磁模块设置在显示模块的两侧的上述现有技术相比，能够在实现手笔双触控功能的同时，使产品结构简单、体积小、厚度薄，并且能够显著降低制造成本。另外，一个实施方式的电磁电容触摸屏，通过将多个电容感应单元和多个电磁感应单元相互间隔排列，能够有效地实现手笔双触控功能。另外，一个实施方式的电磁电容触摸屏，通过在横向和/或纵向 上设置电流方向相反的电磁感应线，能够有效地实现电磁触控功能。另外，一个实施方式的电磁电容触摸屏，通过在纵横交错的电磁感应线所围绕的区域内设置电容感应单元，能够有效地实现手笔双触控功能。另外，一个实施方式的电磁电容触摸屏，通过互容式电容感应电压来实现电容触控功能，能够发挥互容式电容触摸屏的优势。另外，一个实施方式的电磁电容触摸屏，通过架桥结构，能够以简单的结构实现手笔双触控功能，并且能够降低制造成本。
