技术领域

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，影响盖板玻璃的结构强度，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。
本公开实施例提供了一种触摸按键和指纹识别实现装置，如图2所示，包括：
指纹识别传感器21，设置于终端设备的盖板玻璃20的下方，用于采集实施于盖板玻璃20上的指纹信息；
指纹识别电路22，与指纹识别传感器21连接，用于对指纹识别传感器21采集到的指纹信息进行分析处理，获得指纹分析结果；
电容触摸传感器23，设置于指纹识别传感器21的下方，用于采集盖板玻璃20上产生的电容；
电容触摸电路24，与电容触摸传感器23连接，用于对电容触摸传感器23采集到的电容进行分析，获得电容变化量；
开关25，用于当接收到导通信号时，控制指纹识别传感器21和指纹识别电路22导通、且控制电容触摸传感器23和电容触摸电路24断开连接；当接收到断开信号时，控制电容触摸传感器23和电容触摸电路24导通、且控制指纹识别传感器21和指纹识别电路22断开连接。
该实施例中，将电容触摸传感器设置于指纹识别传感器的下方，这样，指纹识别传感器离手指距离较近，当进行指纹识别时，由于指纹识别传感器内部有多层大量的电路，能够起到屏蔽作用，导致电容触摸传感器信号大量减小，无法实现触摸功能。此外，当使用触摸按键功能时，指纹识别传感器内部的多层电路处于悬空状态，由于电容触摸传感器本身的信噪比很高，因此，虽然电容触摸传感器距离手指较远，但指纹识别传感器的厚度不会对电容识别传感器的信号产生大的影响，从而实现电容触摸按键功能。因此，将电容触摸传感器设置于指纹识别传感器的下方这样的堆叠方式能够使得指纹识别功能和触摸按键功能工作时互不影响，实现指纹识别和触摸按键真正一体化。
该技术方案提供的触摸按键和指纹识别实现装置中，将电容触摸传感器设置于指纹识别传感器的下方，根据用户或者上层应用的需要，通过开关控制电容触摸传感器和指纹识别传感器的工作状态，同时利用电容触摸传感器本身信噪比很高的特点，使得电容触摸传感器的工作不受指纹识别传感器的影响，且指纹识别传感器的工作也不受电容触摸传感器的影响，从而实现了将终端设备的指纹识别和触摸按键集成一体化，达到了兼容的目的，此外，由于不需要在盖板玻璃上为放置指纹识别传感器而挖洞，因此不仅提高了整机的外观美感、增强了盖板玻璃的结构强度，且提高了用户的体验度。
在一个实施例中，如图3所示，上述装置还包括主机处理器26，与指纹识别电路22、指纹识别传感器21形成串联回路，用于向开关25发送导通信号或者断开信号，根据指纹识别电路22获得的指纹分析结果进行身份认证。例如，预存的指纹数据中可包括每个用户的身份标识及其指纹特征数据；从指纹分析结果提取出指纹特征后，与指纹数据中每个用户的指纹特征进行比对，从而确定出当前用户的身份。主机处理器26还与电容触摸电路24连接，用于根据电容触摸电路24获得的电容变化量判定盖板玻璃20上是否接收到触摸按键操作。
其中，主机处理器26可以根据用户的指示或者上层应用的需求向开关25发送导通信号或者断开信号，例如，当用户希望进行指纹识别或者上层应用需要进行指纹识别时，用户或者上层应用可指示主机处理器26向开关25发送导通信号；当用户希望进行按键操作 或者上层应用需要进行按键操作时，可指示主机处理器26向开关25发送断开信号。
在一个实施例中，上述主机处理器26包括：
通信接口，用于向开关25发送导通信号或者断开信号；
第一处理器，与指纹识别电路22、指纹识别传感器21形成串联回路，用于将指纹识别电路22获得的指纹分析结果与预存的指纹数据进行比对，确定出当前用户的身份；
第二处理器，与电容触摸电路24连接，用于判断电容触摸电路24获得的电容变化量是否超过预设值，当电容变化量超过预设值时，确定盖板玻璃上接收到触摸按键操作。
在一个实施例中，当指纹识别传感器21和指纹识别电路22断开连接时，指纹识别传感器21处于悬浮状态。
上述触摸按键和指纹识别实现装置的工作原理为：
主机处理器26通过通信接口向开关25发送控制信号(包括导通信号或者断开信号)控制指纹识别传感器21和电容触摸传感器23的工作状态，当主机处理器25向开关25发送导通信号时，开关25根据接收到的导通信号控制指纹识别传感器21和指纹识别电路22导通，并控制电容触摸传感器23和电容触摸电路24断开连接，此时，指纹识别传感器21处于工作状态，当用户手指接触盖板玻璃20的上表面时，指纹识别传感器21采集盖板玻璃20上的指纹信息，并将指纹信息发送给指纹识别电路22，由指纹识别电路22进行分析处理，获得指纹识别结果，并将指纹识别结果发送给主机处理器25中的第一处理器，第一处理器将接收到的指纹识别结果与预存的指纹数据进行比对，确定出当前用户的身份。同时，由于指纹识别传感器21内部设置有多层大量的电路，这些电路会直接起到屏蔽作用，导致电容触摸信号大量减小，无法实现触摸功能，因此，指纹识别传感器21的工作不会影响到电容触摸传感器23。当主机处理器26向开关25发送断开信号时，开关25根据接收到的断开信号控制指纹识别传感器21和指纹识别电路22断开连接，并控制电容触摸传感器23和电容触摸电路24导通，此时，指纹识别传感器21处于悬浮状态，即和主机处理器26断开连接，电容触摸传感器23开始工作。当用户手指触摸盖板玻璃20的上表面时，电容触摸传感器23采集盖板玻璃20上产生的电容，由电容触摸电路24对电容触摸传感器23采集到的电容进行分析，获得电容变化量，并将该电容变化量发送给主机处理器26中的第二处理器，第二处理器将接收到的电容变化量与预设值进行比对，当电容变化量超过预设值时，确定盖板玻璃20上接收到触摸按键操作。
在该实施例中，主机处理器向开关发送控制信号，进而控制电容触摸传感器和指纹识别传感器的工作状态，使得电容触摸传感器的工作不受指纹识别传感器的影响，且指纹识别传感器的工作也不受电容触摸传感器的影响，从而实现了将终端设备的指纹识别和触摸按键集成一体化，达到了兼容的目的，此外，由于不需要在盖板玻璃上为放置指纹识别传感器而挖洞，因此不仅提高了整机的外观美感、增强了盖板玻璃的结构强度，且提高用户的体验度。
另，本公开提供的终端设备的盖板玻璃，无论是一体式的盖板玻璃，还是为放置指纹 识别传感器而挖了一个洞口的盖板玻璃，都是适用于本公开提供的技术方案的，因此，本公开提供的终端设备不需要设计特别样式的盖板玻璃，制作起来十分简单方便。
在一个实施例中，本公开还提供一种终端设备，该终端设备包括上述几个实施例中任一实施例提供的触摸按键和指纹识别实现装置。
对应于上述实施例提供的触摸按键和指纹识别实现装置，本公开实施例还提供一种触摸按键和指纹识别实现方法，如图4所示，该方法包括步骤S401-步骤S402：
在步骤S401中，当接收到导通信号时，采集实施于盖板玻璃上的指纹信息，对采集到的指纹信息进行分析处理，获得指纹分析结果；
在步骤S402中，当接收到断开信号时，采集所述盖板玻璃上产生的电容，对所述采集到的电容进行分析，获得电容变化量。
在一个实施例中，如图5所示，上述方法在实施步骤S401之后，还可以包括步骤S403：对获得的指纹分析结果进行身份认证。或者，上述方法在实施步骤S402之后，还可以包括步骤S404：根据获得的电容变化量判定盖板玻璃上是否接收到触摸按键操作。
上述实施例中，步骤S403可以实施为：将获得的指纹分析结果与预存的指纹数据进行比对，确定出当前用户的身份。步骤S404可以实施为：判断获得的电容变化量是否超过预设值，当电容变化量超过预设值时，确定盖板玻璃上接收到触摸按键操作。
采用本公开实施例提供的触摸按键和指纹识别实现方法，可根据用户或者上层应用的需要，根据接收到的控制信号控制执行指纹识别功能和电容触摸功能，进而根据指纹信息、电容变化量判定出是否接收到了触摸按键操作、以及确定出当前用户的身份，从而实现了将终端设备的指纹识别和触摸按键集成一体化，达到了兼容的目的，不仅提高了整机的外观美感、增强了盖板玻璃的结构强度，而且用户只需要在盖板玻璃上以任意力度进行简单的触摸按压操作，方便用户使用。
