下面结合本申请实施例中的附图对本申请实施例进行描述。
请参阅图1，图1是本申请实施例提供了一种终端设备100的结构示意图，应用处理器AP110、光学指纹模组130和触控显示屏120，所述触控显示屏120包括预设区域，所述光学指纹模组130置于所述预设区域的下方，
所述AP110，用于将所述光学指纹模组的焦距从第一焦距调整为第二焦距；或者，将所述光学指纹模组从第一位置调整到第二位置；
所述AP110，还用于控制所述预设区域的发光单元进行发光，所述发光单元发出的光用于照射所述用户的指纹；
所述光学指纹模组130，用于采集所述发光单元发出的光照射到的用户的指纹。
在一示例中，所述触控显示屏120为LCD显示屏，OLED显示屏，LED显示屏中的其中一种。
在一示例中，预设区域的大小，最大为整个触控显示屏，最小为能够使用户录入足够面积的指纹的大小，等等，本申请不作限定。
在一示例中，预设区域的可以置于触控显示屏的左下角、也可以置于触控显示屏的右下角、也可以置于触控显示屏的右上角，等等，本申请不作限定。
在一示例中，预设区域的形状可以是圆形的、方形的、椭圆形的、菱形等等，本申请不作限定。
在一示例中，预设区域的个数可以是1个，也可以是多个，本申请不作限定。
可见，在本方案中，光学指纹模组的焦距是可以调整的，以及光学指纹模组的位置也是可以调整的，相较于现有技术，光学指纹模组仅仅只能用来采集用户的指纹，本方案的性能较高。
在一示例中，所述AP110具体用于：
当所述AP110检测到最近一次获取到的用户的指纹不满足预设条件时，将所述光学指纹模组130的焦距从第一焦距调整为第二焦距；或者，将所述光学指纹模组130从第一位置调整到第二位置。
其中，光学指纹模组130每一次获取用户的指纹都对应一个获取时间，最近一次获取到的用户的指纹指的是距离当前系统时间最近的一次光学指纹模组130获取到的用户的指纹。比如，光学指纹模组130获取到的用户的指纹有指纹1、指纹2和指纹3，指纹1对应的获取时间为时间1，指纹2对应的获取时间为时间2，指纹3对应的获取时间为时间3，假如时间1与当前系统时间最接近，那么上述的最近一次获取到的用户的指纹为指纹1。
在一示例中，当所述最近一次获取到的用户的指纹的清晰度大于或等于预设清晰度时，则确定所述最近一次获取到的用户的指纹满足预设条件；当所述最近一次获取到的用户的指纹的清晰度小于所述预设清晰度时，则确定所述最近一次获取到的用户的指纹不满足预设条件。
其中，预设清晰度可以是用户自定义的，也可以是所述AP110自定义的，等等。
举例来说，当屏幕上有油污或是水珠时，可能会影响光学指纹模组130获取到的用户的指纹的清晰度，该种情况可通过将光学指纹模组130的焦距调小(也就是将光学指纹模组130的焦距从第一焦距调整为第二焦距，第二焦距小于第一焦距)，或是将光学指纹模组130到用户的指纹的距离调近(也就是将光学指纹模组130从第一位置调整到第二位置，光学指纹模组处于第一位置时光学指纹模组到用户的指纹的距离大于光学指纹模组处于第二位置时光学指纹模组到用户的指纹的距离)，以使得光学指纹模组130获得更清晰的。
在一示例中，所述AP110具体用于：
当所述AP110检测到所述光学指纹模组130到用户的指纹的距离发生变化时，将所述光学指纹模组130的焦距从第一焦距调整为第二焦距；或者，将所述光学指纹模组130从第一位置调整到第二位置。
在一示例中，所述终端设备的设置界面中包括显示设置，所述显示设置中包括贴膜设置，当所述AP110当前读取所述贴膜设置的内容与最近一次读取所述贴膜设置的内容不同时，则确定所述光学指纹模组130到用户的指纹的距离发生变化。
其中，AP110每次读取所述贴膜设置的内容都对应一个读取时间，最近一次读取所述贴膜设置的内容指的是距离当前系统时间最近的一次AP110读取所述贴膜设置的内容。比如，AP110读取所述贴膜设置的内容有内容1、内容2和内容3，内容1对应的读取时间为时间1，内容2对应的读取时间为时间2，内容3对应的读取时间为时间3，假如时间1与当前系统时间最接近，那么上述最近一次读取所述贴膜设置的内容为内容1。
进一步地，所述AP110读取所述贴膜设置的内容是读取所述贴膜设置中的控制按钮的内容。
具体地，如图2所示，图2是本申请实施例提供的一种界面示意图。用户可事先通过设置界面中的显示界面中的贴膜设置来设置终端设备的触控显示屏上是否有贴膜，比如，用户通过贴膜设置中的控制按钮来设置触控显示屏上是否有贴膜，具体有若控制按钮的内容为是，表示触控显示屏上有贴膜，若控制按钮的内容为否，表示触控显示屏上未有贴膜。后续AP110可直接读取贴膜设置的控制按钮的内容来确定触控显示屏上是否粘贴有贴膜。
举例来说，假设AP110最近一次读取所述贴膜设置中的控制按钮的内容为否，AP110当前所述贴膜设置中的控制按钮的内容为是。也就是说，触控显示屏从没有贴膜到有贴膜的状态。光学指纹模块130的采集指纹信息，要保证光学指纹模块130能在触控显示屏120上进行聚焦。当触控显示屏120增加贴膜时，贴膜增加了光学指纹模块130到用户的指纹之间的距离，光学指纹模块130距离用户的指纹距离会增大。如图3所示，触控显示屏120未有贴膜时，光学指纹模组130在焦距为焦距1处，能够清晰采集紧贴于触控显示屏120上的用户的指纹，如果触控显示屏120增加贴膜时，由于光学指纹模块130到用户的指纹距离增大，如果光学指纹模组130的位置不变，光学指纹模组130想要采集到清晰的用户的指纹需要增大光学指纹模组130的焦距(比如图3中的焦距2，焦距2大于焦距1)。
其中，触控显示屏120上未有贴膜是对应的焦距1和触控显示屏120上有贴膜是对应的焦距2是预先设定的。表示只要触控显示屏120上粘贴有贴膜对应的光学指纹模组130的焦距均为焦距2，另外，只要触控显示屏120上粘贴有未贴膜对应的光学指纹模组130的焦距均为焦距1。
进一步地，焦距1的数量可以是1个，也可以是多个，本申请不作限定。另外，焦距2的数量可以是1个，也可以是多个，本申请不作限定。
其中，触控显示屏120上粘贴有贴膜时光学指纹模组130的焦距为焦距2时能采集到清晰的用户的指纹，触控显示屏120上未粘贴有贴膜时光学指纹模组130的焦距为焦距1时能采集到清晰的用户的指纹。
又举例来说，假设AP110最近一次读取所述贴膜设置中的控制按钮的内容为否，AP110当前所述贴膜设置中的控制按钮的内容为是。也就是说，触控显示屏从没有贴膜到有贴膜的状态。光学指纹模块130的采集指纹信息，要保证光学指纹模块130能在触控显示屏120上进行聚焦。当触控显示屏120增加贴膜时，贴膜增加了光学指纹模块130到用户的指纹之间的距离，光学指纹模块130距离用户的指纹距离会增大。如图4所示，触控显示屏120未有贴膜时，光学指纹模组130到用户的指纹的距离为距离1处，能够清晰采集紧贴于触控显示屏120上的用户的指纹。如果触控显示屏120增加贴膜时，由于光学指纹模块130到用户的指纹距离增大，如果光学指纹模组130的焦距不变，光学指纹模组130想要采集到清晰的用户的指纹需要减小光学指纹模组130到用户的指纹的距离(比如图4中将光学指纹模组往靠近触控显示屏120的方向移动，移动的距离等于贴膜的厚度，即距离2-距离1＝贴膜的厚度)。
在一示例中，所述终端设备还包括内置于所述光学指纹模组的光源，
所述AP，还用于在第一时刻控制所述光源进行发光；
所述AP，还用于当在第二时刻所述光学指纹模组接收到经所述贴膜反射的光时，根据所述第一时刻和所述第二时刻确定所述光学指纹模组到用户的指纹的当前距离，当所述光学指纹模组到用户的指纹的当前距离不等于最近一次所述光学指纹模组到用户的指纹的距离时，则确定所述光学指纹模组到用户的指纹的距离发生变化。
其中，AP110每次测量所述光学指纹模组130到用户的指纹的距离都对应一个测量时间，最近一次所述光学指纹模组130到用户的指纹的距离指的是距离当前系统时间最近的一次AP110测量得到的所述光学指纹模组130到用户的指纹的距离。比如，AP110测量所述光学指纹模组130到用户的指纹的距离有距离1、距离2和距离3，距离1对应的测量时间为时间1，距离2对应的测量时间为时间2，距离3对应的测量时间为时间3，假如时间1与当前系统时间最接近，那么上述最近一次所述光学指纹模组130到用户的指纹的距离为距离1。
具体地，在第一时刻控制光源进行发光，发出的光经过经触控显示屏120后有一部分光透射进入贴膜上，另一部分光经触控显示屏120反射进入光学指纹模组130，经触控显示屏120透射进入贴膜上的光的一部分透射进入空气中，另一部分光反射进入触控显示屏120的表面，再透射进入光学指纹模组130。由于触控显示屏120反射进入光学指纹模组130的光与贴膜反射进入光学指纹模组130的光的能量不同，光学指纹模组130可通过能量的大小判断是贴膜发送的光还是触控显示屏120反射的光。
在采集指纹时，需要用户将用户的指纹紧贴贴膜或触控显示屏120，因此光学指纹模组130到用户的指纹的距离＝光学指纹模组130到贴膜的距离。由于光的速度是已知的，光学指纹模组130到贴膜的当前距离等于(第二时刻-第一时刻)*光的速度，再除以2。由于最近一次所述光学指纹模组130到用户的指纹的距离指的是距离是已知的，如果二者的差值要是不同，代表所述光学指纹模组130到用户的指纹的距离发生变化，反之亦然。
在所述光源发光时，触控显示屏120不发光，可见，在确定所述光学指纹模组130到用户的指纹的距离是否时采用光学指纹模组130内置的光源进行的，进而降低了触控显示屏120的功耗，进而提高了触控显示屏120的寿命。
在一示例中，所述终端设备还包括马达150，所述马达150与所述光学指纹模组130连接，所述AP110具体用于：通过所述马达150将所述光学指纹模组从第一位置调整到第二位置。
具体地，马达150与AP110连接，AP110通过控制马达150能够使得光学指纹模组130从第一位置调整到第二位置，第一位置与第二位置的横坐标相同，第一位置与第二位置的纵坐标不同。
在一示例中，所述AP110是在检测到指纹采集指令时，检测最近一次获取到的用户的指纹是否满足预设条件；或者，检测所述光学指纹模组到用户的指纹的距离是否发生变化。其中，指纹采集指令是触控显示屏120在检测到用户针对触控显示屏120的触控操作时，触控显示屏120向AP110发送的；或者，指纹采集指令是指纹支付应用在检测到确定指纹支付时，指纹支付应用向AP110发送的，等等，本申请不作限定。
在一示例中，所述第二焦距和所述第二位置均由以下几个参数中的至少一种确定：1)所述最近一次获取到的用户的指纹；2)当前所述光学指纹模组到用户的指纹的距离；3)当前环境亮度。
举例来说，所述第二焦距是由当前环境亮度确定的。其中，每个环境光范围对应一个光学指纹模组130的焦距，当环境光范围i中包括的任意环境光均大于环境光范围j中包括的任意环境光时，环境光范围i对应的光学指纹模组130的焦距I大于环境光范围j对应的 光学指纹模组130的焦距J，AP110可根据当前环境亮度落入的环境光范围确定第二焦距。由于光圈数值＝1/光圈＝光学指纹模组的焦距/光学指纹模组的口径的直径。可见，光圈数值和光圈成反比，光圈越大，代表环境越暗，光圈越小，代表环境越亮。因此，环境光越亮需要的光学指纹模组的焦距越大。
又举例来说，所述第二焦距是由所述最近一次获取到的用户的指纹。其中，每个清晰度范围对应一个光学指纹模组的焦距，当清晰度范围i中包括的任意清晰度均小于清晰度范围j中包括的任意清晰度时，清晰度范围i对应的光学指纹模组的焦距I小于清晰度范围j对应的光学指纹模组的焦距J，AP110可根据最近一次获取到的用户的指纹的清晰度落入的清晰度范围确定第二焦距。假如最近一次获取到的用户的指纹的清晰度较低时，可将用户的指纹适当的进行局部放大(即将光学指纹模组130的焦距适当调小)，以得到更清晰的用户的指纹。
又举例来说，所述第二焦距是由当前所述光学指纹模组到用户的指纹的距离。其中，每个距离范围对应一个光学指纹模组的焦距，当距离范围i中包括的任意距离均大于距离范围j中包括的任意距离时，距离范围i对应的光学指纹模组的焦距I大于距离范围j对应的光学指纹模组的焦距J，AP110可根据当前所述光学指纹模组到用户的指纹的距离落入的距离范围确定第二焦距。可见，当光学指纹模组130与用户的指纹的距离发生变化时，AP110需调整光学指纹模组130的焦距，以保证光学指纹模块130能对用户的指纹进行聚焦。
又举例来说，所述第二位置是由当前环境亮度确定的。其中，每个环境光范围对应一个光学指纹模组130的位置，当环境光范围i中包括的任意环境光均大于环境光范围j中包括的任意环境光时，环境光范围i对应的光学指纹模组130的位置I到触控显示屏120的距离大于环境光范围j对应的光学指纹模组130的位置J到触控显示屏120的距离，AP110可根据当前环境亮度落入的环境光范围确定第二焦距。
又举例来说，所述第二位置是由所述最近一次获取到的用户的指纹。其中，每个清晰度范围对应一个光学指纹模组130的位置，当清晰度范围i中包括的任意清晰度均小于清晰度范围j中包括的任意清晰度时，清晰度范围i对应的光学指纹模组130的位置I到触控显示屏120的距离小于清晰度范围j对应的光学指纹模组130的位置J到触控显示屏120的距离，AP110可根据最近一次获取到的用户的指纹的清晰度落入的清晰度范围确定第二位置。假如最近一次获取到的用户的指纹的清晰度较低时，可将用户的指纹适当的进行局部放大(即将光学指纹模组130的焦距适当调小)，以得到更清晰的用户的指纹。
又举例来说，所述第二位置是由当前所述光学指纹模组到用户的指纹的距离。其中，每个距离范围对应一个光学指纹模组130的位置，当距离范围i中包括的任意距离均大于距离范围j中包括的任意距离时，距离范围i对应的光学指纹模组130的位置I到触控显示屏120的距离小于距离范围j对应的光学指纹模组130的位置J到触控显示屏120的距离，AP110可根据当前所述光学指纹模组到用户的指纹的距离落入的距离范围得到对应的第二焦距。可见，当光学指纹模组130与用户的指纹的距离发生变化时，AP110需调整光学指纹模组130的位置，以保证光学指纹模块130能对用户的指纹进行聚焦。
在一示例中，所述预设区域包括N个子区域，所述N为大于1的整数，在控制所述预设区域的发光单元进行发光方面，所述AP210具体用于：
控制所述N个子区域中的M个子区域的发光单元进行发光，所述用户的指纹的水平投影位于所述M个子区域，所述M为正整数。
进一步地，N个子区域的大小是相同的，或者，N个子区域中存在至少两个子区域的大小是不相同的。
进一步地，N个子区域的形状是相同的，或者，N个子区域中存在至少两个子区域的形状是不相同的。
举例来说，如图5所示，图5是本申请实施例中提供的另一种界面示意图。如图5所示，预设区域包含的N个子区域的大小和形状均是相同的，预设区域有：子区域A～子区域L。假设用户的指纹水平投影落入子区域B、子区域C、子区域F和子区域G内，此时预设区域中可能只需要点亮子区域B、子区域C、子区域F和子区域G就能够使得光学指纹模组获得较清晰的指纹。可见，在获得较清晰的指纹的前提下，进一步地降低终端设备的功耗。
进一步地，所述M个子区域的发光单元发出的光的亮度为第一亮度，所述当前应用为指纹支付，所述触控显示屏当前显示的界面为支付界面，所述AP210，还用于控制所述触控显示屏中除了所述M个子区域之外的区域的发光单元发出第二亮度的光，所述第二亮度小于所述第一亮度。
进一步地，所述第二亮度为终端设备当前设置的显示亮度。举例来说，如图2所示，所述终端设备200当前设置的显示亮度是用户通过设置界面中包括的亮度设置项设置的触控显示屏220在显示内容时的显示亮度。
举例来说，如图6所示，图6是本申请实施例中提供的另一种界面示意图。如图6所示，预设区域包含的N个子区域的大小和形状均是相同的，预设区域有：子区域A～子区域L。假设用户的指纹水平投影落入子区域B、子区域C、子区域F和子区域G内。由于当前应用为指纹支付，指纹支付需要的指纹等级较大，且当前显示显示的界面为支付界面，因此为了满足能够正常显示支付界面，且采集到较清晰的指纹，本方案AP210控制预设区域中的子区域B、子区域C、子区域F和子区域G发出第一亮度的光，以及控制触控显示屏220除了上述4个子区域之外的区域发出第二亮度的光。
请参见图7，图7为本申请实施例提供的一种指纹的采集方法的流程示意图，应用于终端设备，包括应用处理器AP、光学指纹模组和触控显示屏，所述触控显示屏包括预设区域，所述光学指纹模组置于所述预设区域的下方，包括以下步骤：
S701、所述终端设备将所述光学指纹模组的焦距从第一焦距调整为第二焦距；或者，将所述光学指纹模组从第一位置调整到第二位置。
S702、所述终端设备控制所述预设区域的发光单元进行发光，所述发光单元发出的光用于照射所述用户的指纹。
S703、所述终端设备采集所述发光单元发出的光照射到的用户的指纹。
在一示例中，所述触控显示屏为LCD显示屏，OLED显示屏，LED显示屏中的其中一种。
在一示例中，预设区域的大小，最大为整个触控显示屏，最小为能够使用户录入足够面积的指纹的大小，等等，本申请不作限定。
在一示例中，预设区域的可以置于触控显示屏的左下角、也可以置于触控显示屏的右下角、也可以置于触控显示屏的右上角，等等，本申请不作限定。
在一示例中，预设区域的形状可以是圆形的、方形的、椭圆形的、菱形等等，本申请不作限定。
在一示例中，在一示例中，预设区域的个数可以是1个，也可以是多个，本申请不作限定。
可见，在本方案中，光学指纹模组的焦距是可以调整的，以及光学指纹模组的位置也是可以调整的，相较于现有技术，光学指纹模组仅仅只能用来采集用户的指纹，本方案的性能较高。
在一示例中，所述终端设备将所述光学指纹模组的焦距从第一焦距调整为第二焦距；或者，所述终端设备将所述光学指纹模组从第一位置调整到第二位置的具体实施方式有： 当检测到最近一次获取到的用户的指纹不满足预设条件时，所述终端设备将所述光学指纹模组的焦距从第一焦距调整为第二焦距；或者，所述终端设备将所述光学指纹模组从第一位置调整到第二位置。
其中，光学指纹模组每一次获取用户的指纹都对应一个获取时间，最近一次获取到的用户的指纹指的是距离当前系统时间最近的一次光学指纹模组获取到的用户的指纹。比如，光学指纹模组获取到的用户的指纹有指纹1、指纹2和指纹3，指纹1对应的获取时间为时间1，指纹2对应的获取时间为时间2，指纹3对应的获取时间为时间3，假如时间1与当前系统时间最接近，那么上述的最近一次获取到的用户的指纹为指纹1。
在一示例中，当所述最近一次获取到的用户的指纹的清晰度大于或等于预设清晰度时，则确定所述最近一次获取到的用户的指纹满足预设条件；当所述最近一次获取到的用户的指纹的清晰度小于所述预设清晰度时，则确定所述最近一次获取到的用户的指纹不满足预设条件。其中，预设清晰度可以是用户自定义的，也可以是所述终端设备自定义的，等等。
举例来说，当屏幕上有油污或是水珠时，可能会影响光学指纹模组获取到的用户的指纹的清晰度，该种情况可通过将光学指纹模组的焦距调小(也就是将光学指纹模组的焦距从第一焦距调整为第二焦距，第二焦距小于第一焦距)，或是将光学指纹模组到用户的指纹的距离调近(也就是将光学指纹模组从第一位置调整到第二位置，光学指纹模组处于第一位置时光学指纹模组到用户的指纹的距离大于光学指纹模组处于第二位置时光学指纹模组到用户的指纹的距离)，以使得光学指纹模组获得更清晰的。
在一示例中，所述终端设备将所述光学指纹模组的焦距从第一焦距调整为第二焦距；或者，所述终端设备将所述光学指纹模组从第一位置调整到第二位置的具体实施方式有：当检测到所述光学指纹模组到用户的指纹的距离发生变化时，所述终端设备将所述光学指纹模组的焦距从第一焦距调整为第二焦距；或者，将所述光学指纹模组从第一位置调整到第二位置。
在一示例中，所述终端设备的设置界面中包括显示设置，所述显示设置中包括贴膜设置，当所述终端设备当前读取所述贴膜设置的内容与最近一次读取所述贴膜设置的内容不同时，则确定所述光学指纹模组到用户的指纹的距离发生变化。
其中，所述终端设备每次读取所述贴膜设置的内容都对应一个读取时间，最近一次读取所述贴膜设置的内容指的是距离当前系统时间最近的一次所述终端设备读取所述贴膜设置的内容。比如，所述终端设备读取所述贴膜设置的内容有内容1、内容2和内容3，内容1对应的读取时间为时间1，内容2对应的读取时间为时间2，内容3对应的读取时间为时间3，假如时间1与当前系统时间最接近，那么上述最近一次读取所述贴膜设置的内容为内容1。
进一步地，所述终端设备读取所述贴膜设置的内容是读取所述贴膜设置中的控制按钮的内容。
具体地，如图2所示，用户可事先通过设置界面中的显示界面中的贴膜设置来设置终端设备的触控显示屏上是否有贴膜，比如，用户通过贴膜设置中的控制按钮来设置触控显示屏上是否有贴膜，具体有若控制按钮的内容为是，表示触控显示屏上有贴膜，若控制按钮的内容为否，表示触控显示屏上未有贴膜。后续终端设备可直接读取贴膜设置的控制按钮的内容来确定触控显示屏上是否粘贴有贴膜。
举例来说，假设终端设备最近一次读取所述贴膜设置中的控制按钮的内容为否，终端设备当前所述贴膜设置中的控制按钮的内容为是。也就是说，触控显示屏从没有贴膜到有贴膜的状态。光学指纹模块的采集指纹信息，要保证光学指纹模块能在触控显示屏上进行聚焦。当触控显示屏增加贴膜时，贴膜增加了光学指纹模块到用户的指纹之间的距离，光学指纹模块距离用户的指纹距离会增大。如图3所示，触控显示屏未有贴膜时，光学指纹 模组在焦距为焦距1处，能够清晰采集紧贴于触控显示屏上的用户的指纹，如果触控显示屏增加贴膜时，由于光学指纹模块到用户的指纹距离增大，如果光学指纹模组的位置不变，光学指纹模组想要采集到清晰的用户的指纹需要增大光学指纹模组的焦距(比如图3中的焦距2，焦距2大于焦距1)。
其中，触控显示屏上未有贴膜是对应的焦距1和触控显示屏上有贴膜是对应的焦距2是预先设定的。表示只要触控显示屏上粘贴有贴膜对应的光学指纹模组的焦距均为焦距2，另外，只要触控显示屏上粘贴有未贴膜对应的光学指纹模组的焦距均为焦距1。
进一步地，焦距1的数量可以是1个，也可以是多个，本申请不作限定。另外，焦距2的数量可以是1个，也可以是多个，本申请不作限定。
其中，触控显示屏上粘贴有贴膜时光学指纹模组的焦距为焦距2时能采集到清晰的用户的指纹，触控显示屏上未粘贴有贴膜时光学指纹模组的焦距为焦距1时能采集到清晰的用户的指纹。
又举例来说，假设终端设备最近一次读取所述贴膜设置中的控制按钮的内容为否，终端设备当前所述贴膜设置中的控制按钮的内容为是。也就是说，触控显示屏从没有贴膜到有贴膜的状态。光学指纹模块的采集指纹信息，要保证光学指纹模块能在触控显示屏上进行聚焦。当触控显示屏增加贴膜时，贴膜增加了光学指纹模块到用户的指纹之间的距离，光学指纹模块距离用户的指纹距离会增大。如图4所示，触控显示屏未有贴膜时，光学指纹模组到用户的指纹的距离为距离1处，能够清晰采集紧贴于触控显示屏上的用户的指纹。如果触控显示屏增加贴膜时，由于光学指纹模块到用户的指纹距离增大，如果光学指纹模组的焦距不变，光学指纹模组想要采集到清晰的用户的指纹需要减小光学指纹模组到用户的指纹的距离(比如图4中将光学指纹模组往靠近触控显示屏的方向移动，移动的距离等于贴膜的厚度，即距离2-距离1＝贴膜的厚度)。
在一示例中，所述终端设备还包括内置于所述光学指纹模组的光源，所述方法还包括：
所述终端设备在第一时刻控制所述光源进行发光；
当在第二时刻所述光学指纹模组接收到经所述贴膜反射的光时，所述终端设备根据所述第一时刻和所述第二时刻确定所述光学指纹模组到用户的指纹的当前距离，当所述光学指纹模组到用户的指纹的当前距离不等于最近一次所述光学指纹模组到用户的指纹的距离时，则确定所述光学指纹模组到用户的指纹的距离发生变化。
其中，终端设备每次测量所述光学指纹模组到用户的指纹的距离都对应一个测量时间，最近一次所述光学指纹模组到用户的指纹的距离指的是距离当前系统时间最近的一次终端设备测量得到的所述光学指纹模组到用户的指纹的距离。比如，终端设备测量所述光学指纹模组到用户的指纹的距离有距离1、距离2和距离3，距离1对应的测量时间为时间1，距离2对应的测量时间为时间2，距离3对应的测量时间为时间3，假如时间1与当前系统时间最接近，那么上述最近一次所述光学指纹模组到用户的指纹的距离为距离1。
具体地，在第一时刻控制光源进行发光，发出的光经过经触控显示屏后有一部分光透射进入贴膜上，另一部分光经触控显示屏反射进入光学指纹模组，经触控显示屏透射进入贴膜上的光的一部分透射进入空气中，另一部分光反射进入触控显示屏的表面，再透射进入光学指纹模组。由于触控显示屏反射进入光学指纹模组的光与贴膜反射进入光学指纹模组的光的能量不同，光学指纹模组可通过能量的大小判断是贴膜发送的光还是触控显示屏反射的光。
在采集指纹时，需要用户将用户的指纹紧贴贴膜或触控显示屏，因此光学指纹模组到用户的指纹的距离＝光学指纹模组到贴膜的距离。由于光的速度是已知的，光学指纹模组到贴膜的当前距离等于(第二时刻-第一时刻)*光的速度，再除以2。由于最近一次所述光学指纹模组到用户的指纹的距离指的是距离是已知的，如果二者的差值要是不同，代表所述 光学指纹模组到用户的指纹的距离发生变化，反之亦然。
在所述光源发光时，触控显示屏不发光，可见，在确定所述光学指纹模组到用户的指纹的距离是否时采用光学指纹模组内置的光源进行的，进而降低了触控显示屏的功耗，进而提高了触控显示屏的寿命。
在一示例中，所述终端设备还包括马达，所述马达与所述光学指纹模组连接，所述将所述光学指纹模组从第一位置调整到第二位置的具体实施方式有：所述终端设备通过所述马达将所述光学指纹模组从第一位置调整到第二位置。
具体地，马达与AP连接，终端设备通过AP控制马达能够使得光学指纹模组从第一位置调整到第二位置，第一位置与第二位置的横坐标相同，第一位置与第二位置的纵坐标不同。
在一示例中，所述终端设备是在检测到指纹采集指令时，检测最近一次获取到的用户的指纹是否满足预设条件；或者，检测所述光学指纹模组到用户的指纹的距离是否发生变化。其中，指纹采集指令是触控显示屏在检测到用户针对触控显示屏的触控操作时，触控显示屏向AP发送的；或者，指纹采集指令是指纹支付应用在检测到确定指纹支付时，指纹支付应用向AP发送的，等等，本申请不作限定。
在一示例中，所述第二焦距和所述第二位置均由以下几个参数中的至少一种确定：1)所述最近一次获取到的用户的指纹；2)当前所述光学指纹模组到用户的指纹的距离；3)当前环境亮度。
举例来说，所述第二焦距是由当前环境亮度确定的。其中，每个环境光范围对应一个光学指纹模组的焦距，当环境光范围i中包括的任意环境光均大于环境光范围j中包括的任意环境光时，环境光范围i对应的光学指纹模组的焦距I大于环境光范围j对应的光学指纹模组的焦距J，终端设备可根据当前环境亮度落入的环境光范围确定第二焦距。由于光圈数值＝1/光圈＝光学指纹模组的焦距/光学指纹模组的口径的直径。可见，光圈数值和光圈成反比，光圈越大，代表环境越暗，光圈越小，代表环境越亮。因此，环境光越亮需要的光学指纹模组的焦距越大。
又举例来说，所述第二焦距是由所述最近一次获取到的用户的指纹。其中，每个清晰度范围对应一个光学指纹模组的焦距，当清晰度范围i中包括的任意清晰度均小于清晰度范围j中包括的任意清晰度时，清晰度范围i对应的光学指纹模组的焦距I小于清晰度范围j对应的光学指纹模组的焦距J，终端设备可根据最近一次获取到的用户的指纹的清晰度落入的清晰度范围确定第二焦距。假如最近一次获取到的用户的指纹的清晰度较低时，可将用户的指纹适当的进行局部放大(即将光学指纹模组的焦距适当调小)，以得到更清晰的用户的指纹。
又举例来说，所述第二焦距是由当前所述光学指纹模组到用户的指纹的距离。其中，每个距离范围对应一个光学指纹模组的焦距，当距离范围i中包括的任意距离均大于距离范围j中包括的任意距离时，距离范围i对应的光学指纹模组的焦距I大于距离范围j对应的光学指纹模组的焦距J，终端设备可根据当前所述光学指纹模组到用户的指纹的距离落入的距离范围确定第二焦距。可见，当光学指纹模130与用户的指纹的距离发生变化时，AP110需调整光学指纹模组的焦距，以保证光学指纹模块能对用户的指纹进行聚焦。
又举例来说，所述第二位置是由当前环境亮度确定的。其中，每个环境光范围对应一个光学指纹模组的位置，当环境光范围i中包括的任意环境光均大于环境光范围j中包括的任意环境光时，环境光范围i对应的光学指纹模组的位置I到触控显示屏的距离大于环境光范围j对应的光学指纹模组的位置J到触控显示屏的距离，终端设备可根据当前环境亮度落入的环境光范围确定第二焦距。
又举例来说，所述第二位置是由所述最近一次获取到的用户的指纹。其中，每个清晰 度范围对应一个光学指纹模组的位置，当清晰度范围i中包括的任意清晰度均小于清晰度范围j中包括的任意清晰度时，清晰度范围i对应的光学指纹模组的位置I到触控显示屏的距离小于清晰度范围j对应的光学指纹模组的位置J到触控显示屏的距离，终端设备可根据最近一次获取到的用户的指纹的清晰度落入的清晰度范围确定第二位置。假如最近一次获取到的用户的指纹的清晰度较低时，可将用户的指纹适当的进行局部放大(即将光学指纹模组的焦距适当调小)，以得到更清晰的用户的指纹。
又举例来说，所述第二位置是由当前所述光学指纹模组到用户的指纹的距离。其中，每个距离范围对应一个光学指纹模组的位置，当距离范围i中包括的任意距离均大于距离范围j中包括的任意距离时，距离范围i对应的光学指纹模组的位置I到触控显示屏的距离小于距离范围j对应的光学指纹模组的位置J到触控显示屏的距离，终端设备可根据当前所述光学指纹模组到用户的指纹的距离落入的距离范围得到对应的第二焦距。可见，当光学指纹模组与用户的指纹的距离发生变化时，终端设备需调整光学指纹模组的位置，以保证光学指纹模块能对用户的指纹进行聚焦。
在一示例中，所述预设区域包括N个子区域，所述N为大于1的整数，所述控制所述预设区域的发光单元进行发光的具体实施方式有：所述终端设备控制所述N个子区域中的M个子区域的发光单元进行发光，所述用户的指纹的水平投影位于所述M个子区域，所述M为正整数。
进一步地，N个子区域的大小是相同的，或者，N个子区域中存在至少两个子区域的大小是不相同的。
进一步地，N个子区域的形状是相同的，或者，N个子区域中存在至少两个子区域的形状是不相同的。
举例来说，如图5所示，预设区域包含的N个子区域的大小和形状均是相同的，预设区域有：子区域A～子区域L。假设用户的指纹水平投影落入子区域B、子区域C、子区域F和子区域G内，此时预设区域中可能只需要点亮子区域B、子区域C、子区域F和子区域G就能够使得光学指纹模组获得较清晰的指纹。可见，在获得较清晰的指纹的前提下，进一步地降低终端设备的功耗。
进一步地，所述M个子区域的发光单元发出的光的亮度为第一亮度，所述当前应用为指纹支付，所述触控显示屏当前显示的界面为支付界面，所述方法还包括：控制所述触控显示屏中除了所述M个子区域之外的区域的发光单元发出第二亮度的光，所述第二亮度小于所述第一亮度。
进一步地，所述第二亮度为终端设备当前设置的显示亮度。举例来说，如图2所示，所述终端设备当前设置的显示亮度是用户通过设置界面中包括的亮度设置项设置的触控显示屏在显示内容时的显示亮度。
举例来说，如图6所示，预设区域包含的N个子区域的大小和形状均是相同的，预设区域有：子区域A～子区域L。假设用户的指纹水平投影落入子区域B、子区域C、子区域F和子区域G内。由于当前应用为指纹支付，指纹支付需要的指纹等级较大，且当前显示显示的界面为支付界面，因此为了满足能够正常显示支付界面，且采集到较清晰的指纹，本方案终端设备控制预设区域中的子区域B、子区域C、子区域F和子区域G发出第一亮度的光，以及控制触控显示屏除了上述4个子区域之外的区域发出第二亮度的光。

在一示例中，所述程序具体用于执行以下步骤的指令：
当检测到所述光学指纹模组到用户的指纹的距离发生变化时，将所述光学指纹模组的焦距从第一焦距调整为第二焦距；或者，将所述光学指纹模组从第一位置调整到第二位置。
在一示例中，所述终端设备还包括内置于所述光学指纹模组的光源，所述程序还用于执行以下步骤的指令：
在第一时刻控制所述光源进行发光；
当在第二时刻所述光学指纹模组接收到经所述贴膜反射的光时，根据所述第一时刻和所述第二时刻确定所述光学指纹模组到用户的指纹的距离，当所述光学指纹模组到用户的指纹的当前距离不等于最近一次所述光学指纹模组到用户的指纹的距离时，则确定所述光学指纹模组到用户的指纹的距离发生变化。
在一示例中，所述终端设备还包括马达，所述马达与所述光学指纹模组连接，所述程序具体用于执行以下步骤的指令：

可见，在本方案中，光学指纹模组的焦距是可以调整的，以及光学指纹模组的位置也是可以调整的，相较于现有技术，光学指纹模组仅仅只能用来采集用户的指纹，本方案的性能较高。
