盖板102设置在指纹芯片101的一侧;

本申请实施例中,电子设备可以通过电子设备上的指纹识别模组发射充电指纹采集信号,并且该充电指纹采集信号的频率大于充电器的开关频率,以保证在电子设备在充电状态下能够不受充电器输出的信号的干扰。
可选的,请参阅图1b,图1b是本申请实施例公开的另一种指纹识别模组 的结构示意图。与图1a相比,图1b所示的指纹识别模组10还包括金属圈104,金属圈104环绕设置在盖板102周围。

S201,电子设备接收指纹采集指令。
本申请实施例中,电子设备接收指纹采集指令可以是用户语音输入的,也可以是电子设备感应到用户指纹接触指纹识别模组之后产生的。指纹采集指令用于触发电子设备开启指纹采集功能,触发电子设备发射指纹采集信号。
S202,电子设备发射充电指纹采集信号,充电指纹采集信号的频率大于预设频率,预设频率为电子设备的充电器的开关频率,充电指纹采集信号用于采集用户指纹图像数据。
本申请实施例中,电子设备可以通过电子设备上的指纹识别模组发射充电指纹采集信号,并且该充电指纹采集信号的频率大于充电器的开关频率,以保证在电子设备在充电状态下能够不受充电器输出的信号的干扰。充电器的开关频率是充电器输出的电压信号(例如,电压脉冲信号)的频率。充电器输出的电压脉冲信号的频率一般为几百KHz。例如,充电器输出的电压脉冲信号的频率为500KHz时,可以设置指纹识别模组发射充电指纹采集信号的频率为1.5MHz。其中,充电指纹采集信号用于采集用户指纹图像数据。
可选的,充电指纹采集信号的幅值大于预设幅值,预设幅值为充电器输出的电压信号的幅值。
本申请实施例中,为了进一步防止充电器输出的电压信号对充电指纹采集信号的干扰,可以设置充电指纹采集信号的幅值大于充电器输出的电压信号的幅值。
例如,若充电器输出的电压信号的幅值为1.8V,则可以设置充电指纹采集信号的幅值为6V。
实施图2所示的方法,电子设备可以发射大于充电器的开关频率的充电指纹采集信号来采集用户指纹图像数据,以使充电指纹采集信号与充电器的开关频率错开,避免充电器输出的电压信号干扰充电指纹采集信号,可以在对电子设备充电时,减少充电器对指纹图像的噪声干扰。
请参阅图3,图3是本申请实施例公开的另一种指纹识别方法的流程示意图,如图3所示,该指纹识别方法包括如下步骤。
S301,电子设备接收指纹采集指令。
其中,步骤S301可以参见图2所示的步骤S201。此处不再赘述。
S302,电子设备检测电子设备是否处于充电状态。若是,则执行步骤S303,如否,则执行步骤S304。
本申请实施例中,电子设备可以通过电子设备内的充电IC检测电子设备是否处于充电状态。当电子设备检测到电子设备处于充电状态时,电子设备发射充电指纹采集信号。当电子设备检测到电子设备不处于充电状态时,执行步骤S304。
S303,电子设备发射充电指纹采集信号,充电指纹采集信号的频率大于预设频率,预设频率为电子设备的充电器的开关频率,充电指纹采集信号用于采集用户指纹图像数据。
本申请实施例中,充电指纹采集信号的频率大于电子设备的充电器的开关频率。更进一步的,充电指纹采集信号的频率与电子设备的充电器的开关频率的差值满足一定的条件。假设充电指纹采集信号的频率为f1,充电器的开关频率为f2。则f1与f2满足如下至少一种条件:
(1)、(f1-f2)/f1大于或等于50%,并且(f1-f2)/f1小于或等于-50%;
(2)、(f1-f2)/f2大于或等于50%,并且(f1-f2)/f2小于或等于-50%;
(3)、(f1-f2)/f1大于或等于80%,并且(f1-f2)/f1小于或等于-80%;
(4)、(f1-f2)/f2大于或等于80%,并且(f1-f2)/f2小于或等于-80%;
(5)、(f1-f2)/f1大于或等于90%,并且(f1-f2)/f1小于或等于-90%;
(6)、(f1-f2)/f2大于或等于90%,并且(f1-f2)/f2小于或等于-90%。
一般而言,充电指纹采集信号的频率与电子设备的充电器的开关频率的差 值的绝对值越大,充电器对电子设备发射的充电指纹采集信号的干扰越小。
S304,电子设备判断电子设备的显示信号的频率与正常指纹采集信号的频率的差值是否大于预设阈值。若是,则执行步骤S303,若否,则执行步骤S305。
本申请实施例中,当电子设备检测到电子设备不处于充电状态时,电子设备判断电子设备的显示信号的频率与正常指纹采集信号的频率的差值是否大于预设阈值。电子设备的显示信号可以是电子设备的显示屏显示的任何信号的频率,例如,电子设备的显示屏的刷新频率。对于包括液晶显示屏的电子设备而言,电子设备的显示信号还可以是电子设备的液晶显示屏的每一行液晶显示管的显示频率。例如对于分辨率为1024*720的液晶显示屏而言,如果电子设备的液晶显示屏的刷新频率为60Hz,则电子设备的液晶显示屏的每一行液晶显示管的显示频率为60Hz*720=43.2KHz。如果正常指纹采集信号的频率与电子设备的液晶显示屏的每一行液晶显示管的显示频率的差值小于预设阈值时,则电子设备的液晶显示屏的每一行液晶显示管的显示会对正常指纹采集信号带来干扰。
其中,预设阈值越大,则表明电子设备的显示信号对正常指纹采集信号的干扰越小。
举例来说,如果电子设备的显示信号的频率为f1,正常指纹采集信号的频率为f2,则可以设置预设阈值为f1*50%、f2*50%、f1*80%、f2*80%、f1*90%、f2*90%中的任一种。
S305,电子设备发射显示指纹采集信号,显示指纹采集信号的频率与正常指纹采集信号的频率的差值大于预设阈值。
本申请实施例中,当电子设备的显示信号的频率与正常指纹采集信号的频率的差值小于或等于预设阈值时,电子设备发射显示指纹采集信号。其中,显示指纹采集信号的频率与正常指纹采集信号的频率的差值大于预设阈值。
可选的,显示指纹采集信号的幅值与电子设备的显示信号的幅值的差值大于预设幅值。
本申请实施例中,为了进一步防止电子设备的显示信号对显示指纹采集信号的干扰,可以设置显示指纹采集信号的幅值与电子设备的显示信号的幅值的差值大于预设幅值。预设幅值可以预先设置好,并存储在电子设备的非易失性 存储器中。
例如,若电子设备的显示信号的幅值为1.8V,预设幅值为4V,则可以设置显示指纹采集信号的幅值为6V。
本申请实施例中,当电子设备处于充电状态时,电子设备可以发射大于充电器的开关频率的充电指纹采集信号来采集用户指纹图像数据,以使充电指纹采集信号与充电器的开关频率错开,避免充电器输出的电压信号干扰充电指纹采集信号。可以在对电子设备充电时,减少充电器对指纹图像的噪声干扰。当电子设备不处于充电状态时,电子设备可以发射频率大于正常指纹采集信号预设阈值的显示指纹采集信号,以使显示指纹采集信号的频率与电子设备的显示信号的频率错开,避免电子设备的显示信号干扰充电指纹采集信号。
