具体实施方式
为了使本技术领域的人员更好地理解本申请方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有 其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象,而不是用于描述特定顺序。此外,术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元,或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。
在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
本申请实施例所涉及到的电子设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS),终端设备(terminal device)等等。为方便描述,上面提到的设备统称为电子设备。
当手机在充电时,由于充电器内的开关管在高速导通和闭合的时候,会形成高频干扰信号,即共模干扰信号。此时,如果用户使用指纹解锁,共模干扰信号会对指纹识别模组发射的指纹采集信号会带来干扰。因此,本申请实施例提供了一种指纹识别模组及电子设备,可以在电子设备充电时,减少共模干扰信号对指纹采集信号的干扰。
下面对本申请实施例进行详细介绍。
请参阅图1,图1是本申请实施例公开的一种指纹识别模组的结构示意图,如图1所示,该指纹识别模组10包括指纹芯片101、盖板102、电路板103以及金属圈104,其中:
盖板102设置在指纹芯片101的一侧;
电路板103设置在指纹芯片101远离盖板102的另一侧;
金属圈104环绕盖板102,金属圈104与电子设备的导电补强板20电连接。
本申请实施例中,金属圈104也叫指纹装饰圈、指纹bezel、指纹ring。金属圈104环绕盖板102的方式可以为金属圈104与盖板102电连接环绕。金属圈104可以为圆形、椭圆形、矩形、多边形中的一种或多种组合。金属圈104的材质可以是不锈钢、金、银、铜等。
当电子设备在充电时,如果用户使用电子设备上的指纹识别模组10进行指纹解锁,充电器产生的共模干扰信号会对纹识别模组10发射的指纹采集信号会带来干扰。为了降低共模干扰信号对纹识别模组10发射的指纹采集信号带来的干扰,本申请实施例通过将指纹识别模组10中的金属圈104与电子设备的导电补强板20电连接,增大用户手指与金属圈104之间的电容,以使指纹芯片发射的指纹采集信号的回流路径变短,从而减少共模干扰信号对指纹采集信号的干扰。
其中,导电补强板20可以位于电路板103上。导电补强板20可以是不锈钢补强板、钢板、钢补等可以导电的补强板。
如图2所示,图2是本申请实施例公开的一种指纹采集信号回流路径的示意图。如图2所示,指纹识别模组10发射的指纹采集信号有两条回流路径。一条是经过手指(finger)、金属圈(brezel)和传感器(sensor)回流,包括手指的电容C finger、金属圈的电阻R bezel、金属圈的电容C bezel、指纹识别模组10的传感器的电容C sensor。另一条是经过人体(body)和柔性电路板(FlexiblePrintedCircuit,FPC)回流。包括手指的电容C finger、人体的电容C body、柔性电路板的电容C FPC
指纹采集信号的回流路径越短,共模干扰信号对指纹采集信号带来的干扰就越小。由于指纹采集信号的频率为几百KHz甚至几个MHz,频率较高,为了保证高频信号的通过,需要将指纹采集信号回流路径中的电容的容值增大,以缩短指纹采集信号的回流路径。由于手指的电容C finger、指纹识别模组10的传感器的电容C sensor、人体的电容C body、柔性电路板的电容C FPC的大小不容易改变,本申请实施可以通过调整金属圈的电阻R bezel与金属圈的电容C bezel的大小,来缩短指纹采集信号的回流,进而降低共模干扰信号对指纹采集信号带来的干扰。具体的,可以通过降低金属圈的电阻R bezel、增大金属圈的电容C bezel来实 现。
一般而言,在现有技术中,金属圈104仅仅是起到装饰作用。而本申请实施例中,将金属圈104与电子设备的导电补强板20电连接。当用户使用手指触摸(或按压)指纹识别模组10的金属圈104时,用户手指与金属圈104之间形成的电容C bezel=εs/4πkd。其中,ε为用户手指与金属圈104之间的电介质的介电常数,s为用户手指与金属圈104之间的相对面积,k为静电常数,d为用户手指与金属圈104之间的距离。由于用户手指与金属圈104之间的距离很难改变,用户手指与金属圈104之间的电介质也很难改变。因此,要想提高的C bezel大小,可以通过增加用户手指与金属圈104之间的相对面积。从图1可以看出,金属圈104本身的面积非常小,将金属圈104与电子设备的导电补强板20电连接后,用户手指与金属圈104之间的相对面积相当于用户手指与导电补强板20之间的相对面积。由于导电补强板20的面积远大于手指的面积,所以用户手指与导电补强板20之间的相对面积要远大于用户手指与金属圈104之间的相对面积,进而可以提高的C bezel大小,缩短指纹采集信号的回流,降低共模干扰信号对指纹采集信号带来的干扰。
请参阅图3,图3是本申请实施例公开的另一种指纹识别模组的结构示意图。如图3所示,该指纹识别模组10包括指纹芯片101、盖板102、电路板103以及金属圈104,其中:
盖板102设置在指纹芯片101的一侧;
电路板103设置在指纹芯片101远离盖板102的另一侧;
金属圈104环绕盖板102,金属圈104与电子设备的导电补强板20电连接;
导电补强板20通过导电布电连接电子设备的中框30。
其中,导电补强板20也可以通过其他的导电体(例如,导电板、导线、导电泡棉等)电连接电子设备的中框30。
从图3可以看出,金属圈104本身的面积非常小,将金属圈104与电子设备的导电补强板20电连接,并且将导电补强板20与中框30电连接之后,用户手指与金属圈104之间的相对面积相当于用户手指与导电补强板20和中框30之间的相对面积。由于导电补强板20和中框30的面积远大于手指的面积, 所以用户手指与导电补强板20和中框30之间的相对面积要远大于用户手指与金属圈104之间的相对面积,进而可以进一步提高C bezel的大小,进一步缩短指纹采集信号的回流,进一步降低共模干扰信号对指纹采集信号带来的干扰。
可选的,金属圈104与导电补强板20通过导电泡棉电连接。
其中,导电泡棉具有表面电阻率低、耐磨性好、适用温度范围大、适用湿度范围大、阻燃性好等优点。同时导电泡棉还具有材质轻、抗氧化、抗腐蚀等优点。
具体的,可以通过在金属圈104上涂上导电胶等导电粘合剂,通过导电胶将金属圈104与导电泡棉连接,然后在导电补强板20上也涂上导电胶,通过导电胶将导电补强板20与导电泡棉连接,从而实现金属圈104与导电补强板20通过导电泡棉电连接。还可以直接在金属圈104与导电补强板20之间填充导电泡棉。当然,前提是导电泡棉不与电子设备上除了金属圈104与导电补强板20之外的其他导电部件连接。
可选的,导电泡棉包括镀镍铜导电泡棉、镀金导电泡棉、镀碳导电泡棉、镀锡导电泡棉、导电铝箔泡棉、导电铜箔泡棉中的任一种或多种组合。
可选的,金属圈104与导电补强板20通过导电海绵电连接。
其中,导电海绵可以包括导电海绵条、导电海绵管、导电海绵板等。
可选的,金属圈104与导电补强板20通过导电布连接。
导电布是以纤维布(一般常用聚酯纤维布)为基材,经过前置处理后施以电镀金属镀层使其具有金属特性而成为导电纤维布。导电布具有重量轻、易剪裁、抗氧化、抗腐蚀等优点。
可选的,导电布包括镀镍导电布、镀金导电布、镀炭导电布、铝箔纤维复合布中的任一种或多种组合。
可选的,金属圈104与导电补强板20通过导线电连接。
其中,导线的材质可以是铜、金、银、铝等电阻率较低的材料。可以设置导线的直径较大,以使得导线的电阻较低。
可选的,金属圈104与导电补强板20通过导电板电连接。
其中,导电板材质可以是铜、金、银、铝等电阻率较低的材料。导电板的一端可以焊接在金属圈104上,导电板的另一端可以焊接在导电补强板20上。
可选的,请参阅图4,图4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,如图4所示,该指纹识别模组10包括指纹芯片101、盖板102、电路板103以及金属圈104,其中:
盖板102设置在指纹芯片101的一侧;
电路板103设置在指纹芯片101远离盖板102的另一侧;
金属圈104环绕盖板102,金属圈104与电子设备的导电补强板20电连接;
指纹芯片101包括指纹传感器1011,指纹传感器1011用于发射指纹采集信号,指纹采集信号用于采集用户指纹图像。
本申请实施例中,电子设备的指纹识别模组10可以接收用户输入的指纹采集指令。当接收到指纹采集指令之后,指纹识别模组10的指纹传感器1011发射指纹采集信号,指纹采集信号用于采集用户指纹图像。
其中,指纹采集指令用于触发电子设备开启指纹采集功能,触发电子设备的指纹识别模组10的指纹传感器1011发射指纹采集信号。
可选的,指纹采集信号的频率与电子设备的充电器输出的电压信号的频率的差值大于预设阈值;指纹采集信号的幅值与充电器输出的电压信号的幅值大于预设幅值。
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10发射指纹采集信号,并且该指纹采集信号的频率与电子设备的充电器输出的电压信号的频率的差值大于预设阈值,以保证在电子设备在充电状态下能够不受充电器输出的电压信号的干扰。预设阈值可以预先设置并存储在电子设备的非易失性存储器中。
进一步的,指纹采集信号的幅值与充电器输出的电压信号的幅值大于预设幅值。可以防止充电器输出的电压信号对指纹采集信号的干扰。预设幅值可以预先设置并存储在电子设备的非易失性存储器中。
请参阅图5,图5是本申请实施例公开的一种指纹采集方法的流程示意图,如图5所示,该指纹采集方法包括如下步骤。
S501,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用户指纹接触之后产生的。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。
S502,电子设备的指纹识别模组发射指纹采集信号,指纹采集信号的频率与电子设备的充电器输出的电压信号的频率的差值大于预设阈值;指纹采集信号的幅值与充电器输出的电压信号的幅值大于预设幅值;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指纹采集信号,并且该指纹采集信号的频率与电子设备的充电器输出的电压信号的频率的差值大于预设阈值,以保证在电子设备在充电状态下能够不受充电器输出的电压信号的干扰。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指纹采集信号的频率为1.5MHz。其中,指纹采集信号用于采集用户指纹图像数据。指纹采集信号的幅值与充电器输出的电压信号的幅值大于预设幅值,可以进一步防止充电器输出的电压信号对指纹采集信号的干扰,可以设置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,预设幅值为4V,则可以设置指纹采集信号的幅值为6V。
实施图5所示的方法,设置电子设备的指纹识别模组的发射指纹采集信号的频率与电子设备的充电器输出的电压信号的频率的差值大于预设阈值,以使指纹采集信号与充电器输出的电压信号的频率错开,减少充电器输出的电压信号对指纹采集信号的干扰。设置指纹采集信号的幅值与充电器输出的电压信号的幅值大于预设幅值,以使指纹采集信号与充电器输出的电压信号的幅值差别较大,可以在对电子设备充电时,进一步减少充电器输出的电压信号对指纹采集信号的干扰。
