为了解决现有技术中的触控显示屏与指纹传感部分离设计使终端占用较大空间的问题，本发明提供了一种指纹采集识别方法、装置及终端，以下结合附图以及几个实施例，对本发明进行进一步详细说明。应当理解，此处所描述 的具体实施例仅仅用以解释本发明，并不限定本发明。
方法实施例
本发明实施例提供了一种指纹采集识别方法，参见图3，该方法包括：
S301、通过触控显示屏上的指纹传感部采集指纹信息；
S302、对所述指纹信息进行识别比对。
本发明通过在触控显示屏上设置指纹传感部，并通过该指纹传感部来采集用户的指纹信息，即本发明通过将触控显示屏与指纹传感部一体化设计，从而降低了终端的占用空间。
本发明的指纹传感部具有认证用户指纹的功能，并同时能够实现触控功能，即本发明的指纹传感部能够同时实现指纹识别模式和触控模式。
本发明的指纹传感部在触控显示屏上显示为一个指纹图标或其他图标，当然本领域的技术人员也可以将该指纹传感部统一设置在触控显示屏的某一个固定位置处，如触控显示屏的左下角、右下角等，具体指纹传感部的设置位置可以根据用户的使用需要而定。
本发明实施例中步骤S301具体包括：通过触控显示屏上指纹传感部的发射极走线和接收极走线采集所述指纹信息。
具体的，本发明实施例是通过所述触控显示屏上指纹传感部的发射极走线发射信号，本发明的发射极走线和接收极走线具体如图3所示，其中，Tx代表电容式触摸屏发射极走线，Rx代表电容式触摸屏接收级走线。
需要说明的是，本发明指纹传感部的发射极走线和接收极走线是在现有触控显示屏的布线的基础上进行多触控布线，具体设置思路为，现有的电容式触摸屏走线为：人体手指触摸大小相当于一个10mm*10mm的正方形格子，触控走线设计时，常规设计为5mm*5mm的单元格作为一个触控模块。例如：触控区域实际为100mm*50mm，需要走线Tx为100/5＝20条，需要Rx走线为50/5＝10条，而指纹识别走线为精细版的电容屏，即指纹传感部内的走线密度高于触控显示屏的走线密度，具体设计为，所述发射极走线之间的间距，以及所述接收极走线之间的间距均小于50um，分辨率达500dpi，以5寸触摸屏为例，有效触控区域为110mm*62mm，单做触摸屏需要Tx：22根，Rx：12根。此时如果将Tx：2200根，Rx：1200根，即可以实现指纹采集的功能。
具体实施时，本发明通过触控显示屏上指纹传感部的接收极走线接收指纹对该发射信号反射回的信号，柔性电路板FPC根据该反射回的信号得到所述指纹信息。
指纹识别处理方式为：通过密集的Tx发射信号，Rx接受信号，再通过FPC传输回来，得到所需的指纹图像，再经过数字信号处理器(Demand-Side Platform，DSP)指纹图像处理芯片提取出指纹特征点，从现有录制的指纹库中进行对比，输出匹配结果。
