本申请要求于2015年1月30日提交中国专利局、申请号为201510050893.5的中国专利申请的优先权，以及2015年1月7日提交中国专利局、申请号为201510007416.0的中国专利申请的优先权，以上全部内容通过引用结合在本申请中。
技术领域
本公开涉及电子器件技术领域，尤其涉及触摸按键和指纹识别实现装置、方法及终端设备。
背景技术
随着终端设备手机功能的不断增多，终端设备越来越多的新功能也给用户带来更多便利。
目前指纹识别功能开始受到各大终端设备厂商的青睐。目前的终端设备，如手机、平板电脑等，在设计指纹识别功能时，基本都是采用物理按键来结合指纹识别功能，以达到兼容按键和指纹识别的目的，切面图如图1所示。通常采用这种设计时，由于物理按键02在按压时需要固定的行程才能生效，所以需要在盖板玻璃01上，指纹识别的区域挖一个对应的洞口，当用户轻触指纹识别传感器03，系统只识别为指纹；当用户按压指纹识别传感器03、并达到一定行程时，会触发物理按键02，则系统可以识别成指纹和按键两个动作，然后再根据上层需要提取对应的动作。但是上述结构，不仅会影响终端设备整机的外观美感，而且也影响用户操作的便利性。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图2是根据一示例性实施例示出的触摸按键和指纹识别实现装置的框图。如图2所示，装置包括：指纹识别传感器21、指纹识别电路22、多合一开关23和触摸按键电路24，指纹识别传感器21包括多个子传感器。
各个子传感器分别与指纹识别电路22连接，各个子传感器分别与多合一开关23连接，多合一开关23与触摸按键电路24连接。
指纹识别传感器21，用于当多合一开关23为开路时，将各个子传感器检测产生的信号分别传输给指纹识别电路22，当多合一开关23为关闭时，通过多合一开关23将各个子传感器检测产生的信号合并为触控信号传输给触摸按键电路24；
指纹识别电路22，用于对各个子传感器检测产生的信号进行处理；
触摸按键电路24，用于根据合并所得的触控信号判断是否产生触摸操作。
在一实施例中，如图3和图4所示，多个子传感器按点阵方式或长方形矩阵方式排列。
指纹传感器上排列多个子传感器32，子传感器32用于探测指纹的各个细微的关键点信息，可以根据这些关键节点信息，还原指纹的图像，由对比分析是否与采样图样一致。
无论是点阵方式，还是长方形矩阵方式，都是通过子传感器阵列将手指的指纹信号传输到指纹识别电路22，再经过信号过滤，放大，AD采样等处理，提供给指纹芯片足够的数字信号。因为这些子传感器阵列无法提供足够的信号来探测手指触摸，这受限于单独的指纹传感器太小，信号量也低，而且响应面积也极小，灵敏度低，无法实现正常的手指触摸功能。因此，将多合一开关23关闭，通过多合一开关23将各个子传感器检测产生的信号合并为触控信号传输给触摸按键电路24，由此，能够为触摸按键电路24提供足够能量的信号。
本公开的实施例提供的技术方案可以包括以下有益效果：使用共用的指纹识别传感器实现指纹识别和触摸按键的功能，将指纹识别和触摸按键功能的外部部件集成为一个部件，提高了电子设备的集成度，增加了用户操作的便捷性。

本实施例是通过在指纹识别架构上，共用传感器，添加新的触摸按键架构来实现指纹识别和触摸按键的兼容功能。
多合一开关23根据终端设备中主机31的指令进行开路和关闭，当需要响应指纹识别时，多合一开关23是开路，则指纹识别电路22取得各个子传感器32的信号，完成指纹识别功能；当主机31响应手指触控功能时，则多合一开关23关闭，所有子传感器32都连成一个大的传感器，触摸按键电路24通过这个大传感器取得手指触控信号，并完成手指触控功能。通过上层主机31的需求，将各个子传感器连接成一个大的传感器，从而能给触摸按键电路24提供足够强的信号，同时保证了手指触控要求的灵敏度，响应面积，和响应速度。
在一实施例中，指纹识别电路22可包括：
信号处理子模块，用于将各个子传感器32检测产生的信号转换为数字信号，将数字信号传输给终端设备中主机31。
