平板电脑或超级本电脑等电子产品基于便于携带，轻薄等特性获得了越来越广泛的应用。随着电子技术及通信技术的发展，电脑运算速度越来越快，可以把越来越多的功能集成在又轻又薄的平板电脑里。除了满足娱乐休闲等功能需求外，越来越多的办公需求也可以由平板电脑满足。
双屏平板电脑是平板电脑的一种改进或一种变形。市面的双屏电脑大多通过转轴连接两个平板电脑，而且两个平板之间可以做180度的开合。再有，平板电脑上大多配备有触摸屏，通过触摸屏实现对平板电脑的触摸操作。
通过单个的触摸屏和显示屏实现单个平板电脑的触摸控制已经发展起来的技术。现有的双屏平板电脑则采用两个触控集成电路分别控制两个触摸屏，一方面，需要较高的硬件成本，另一方面，当需要两个触摸屏和两个显示屏进行扩展显示或触控或配合显示或触控时，两个触控集成电路之间的通信和线路设计、软件设计会变得异常复杂，这给系统设计带来了很大的不便。因此，现有双屏平板电脑的两个触摸屏之间是独立的驱动并独立的实现触摸控制的。

图1示出了本发明的双屏平板电脑的触摸屏结构框图。本发明的双屏平板电脑包括第一显示屏103和第二显示屏104(第一显示屏103和第二显示屏104在图1中未示出)，第一触摸屏101和第二触摸屏102，所述第一触摸屏101与所述第一显示屏103相贴合；所述第二显示屏104与所述第二触摸屏102相贴合；所述第一显示屏103与所述第二显示屏104通过转轴或铰链相连接且可展开或闭合；所述第一触摸屏101和第二触摸屏102同时与一个单一的触摸主控模块301电连接。
需要说明的是，所述的第一显示屏103与第一触摸屏101以常规的方式进行贴合，即第一触摸屏101叠置于第一显示屏103的上面，中间以光学胶或透明的粘结材料粘贴，通过第一触摸屏101可以实现对第一显示屏103中显示内 容的控制；而第二显示屏102与第二显示屏104设置为与第一显示屏103和第一触摸屏101相同或相似的结构。第一显示屏103、第二显示屏104、第一触摸屏101、第二触摸屏104中通过柔性电路板或线缆与其中的电子元器件相连接，并通过边缘部分导出或彼此电连接。
所述第一显示屏103与所述第二显示屏104通过转轴或铰链相连接且可展开或闭合；需要说明的是，在转轴和铰链中可以设置阻尼结构，以便在第一显示屏103和第二显示屏104打开后可以保持在一定的角度；这里所述的第一显示屏103和第二显示屏104上已经分别粘贴了第一触摸屏101和第二触摸屏102，为了描述的简明而省略描述。
需要说明的是，所述的“一个单一的触摸主控模块301”指的是同一颗触摸控制集成电路或者是基于同一个触摸集成控制电路的软件和硬件的集合。触摸主控模块301可以体现为一颗独立形态集成电路芯片、一块相对独立的电路板或者两块或多块分立形态的集成电路芯片或包含集成电路芯片的电路板；内在地，这些分立形态的集成电路芯片或电路板是基于一个同一个触摸控制内核或一个同一的触摸控制中央处理系统。
本发明的双屏平板电脑采用一颗单独的触控集成电路或触摸主控模块对两个触摸屏进行电连接和控制，一方面降低了硬件设计成本；另一方面，由于使用同一个触控集成电路或触控主控模块，可以基于同一个操作系统实现对两个触摸屏的控制，这样，再使用两个触摸屏在进行控制时，可以很便捷地与显示系统进行配合，实现两个触摸屏的单独控制和扩展控制，以及显示屏的单独显示和扩展显示，镜像显示等功能。能够简化软件系统的设计，提高系统运行效率，提升用户体验。
图2示出了本发明的双屏平板电脑的第二实施例的触摸屏结构框图。如图2所示，本发明的双屏平板电脑的触摸主控模块301还可以包括控制所述第一触摸屏101和第二触摸屏102进入扩展触控模式或单独触控模式的触摸模式选 择模块301。单独触控模式即第一触摸屏101和第二触摸屏102分别作为一个独立的触摸屏进行工作，分别独立地进行触摸感测部件的驱动和扫描，包括使其中的一个触摸屏为关闭而另一个触摸屏是开启的状态，或者两个触摸屏都是开启的状态或都是关闭的状态。而扩展触控模式则是第一触摸屏101和第二触摸屏102合二为一的作为一个触摸屏器件进行驱动和扫描。例如以水平方向X向的坐标轴为例，假设总共有100个坐标点，那么，第一触摸屏101对坐标范围在(0，Y)～(50，Y)坐标范围内的显示对象触摸扫描和触摸控制，而第二触摸屏102则对坐标范围在(51，Y)～(100，Y)坐标范围内的对象进行触摸扫描和触摸控制。本发明通过触摸模式选择模块301在一个硬件或软件系统内实现第一触摸屏101和第二触摸屏102多种触控模式的调节和配合，提高双屏平板电脑使用的便捷性，并满足特定应用场景对显示和触摸控制模式的要求。

另外，本发明的双屏平板电脑的所述触摸主控模块201通过单独USB接口202与双屏平板电脑的主板控制电路301进行电连接和数据通信。USB接口作为 通用的数据信号接口，具有很好的兼容性和便捷性，本发明采用USB接口统一将两个触摸屏连接至主板控制电路，便于所述触摸屏与主板控制电路进行数据通信和控制。
图4示出了本发明的双屏平板电脑的第三实施例的触摸屏结构示意图。如图4所示，所述第一触摸屏101包括N个第一触控感测电极11，所述第二触摸屏102包括M个第二触控感测电极12；所述N个第一触控感测电极11和M个第二触控感测电极12依次与所述触控集成电路205的触控电极驱动和扫描接口电连接，其中N和M均为自然数。M与N的数值可以相同也可以不相同。如图4所示，在第一触摸屏101中，第1～第N/2个第一触控感测电极11是水平方向上的触摸感测电极，第N/2+1～第N个第一触控感测电极11是垂直方向上的感测电极，需要注意的是，图4中所示的水平和垂直方向只是示例。在触控领域的技术人员可以对触摸感测电极的形状和排列方式进行组合和调整，本发明并不限定触摸感测的方式以及具体的触摸感测电极的结构。第二触摸屏102的触控感测原理与第一触摸屏101的结构相同，不再赘述。
需要注意的是，所述N个第一触控感测电极11和M个第二触控感测电极12依次与所述触控集成电路的管脚直接相连接，也可以通过转接口、柔性电路板等器件或其他外围电路例如开关选择电路与所属触控集成电路的管脚间接相连接。本发明的双屏平板电脑采用一个触控集成电路控制第一触摸屏101和第二触摸屏102，是的双屏平板电脑的两个显示屏和两个触摸屏之间可以实现自由的配合和控制，避免了采用两个独立的触摸感测系统所带来的硬件和软件通信方面诸多问题，提高了用户的操作的便捷性，也降低了硬件成本。
