技术领域
本公开涉及通信技术领域,尤其涉及一种指纹识别方法及移动终端。
背景技术
指纹识别如今已逐渐成为移动终端的标配功能,通过指纹识别可以实现移动终端的解锁、加密、支付等。通常的指纹模块需要在玻璃内层内置指纹传感器,并固定开孔。其中为了提升移动终端的屏占比,以及使用户更加方便的使用指纹识别,全屏指纹技术已经成为指纹识别发展的一个新方向。
现有的移动终端指纹识别都是通过阵列去采集手指纹表面的纹路,获取指纹图像。主要方式有电容式,光电,超声波等。下面以目前应用最广泛的电容式指纹为例进行说明。电容式指纹识别是由电容阵列构成的,内部大约包含1万只微型化的电容器(不同厂家内部点阵数量不同,目前有152×200、256×300、128×128等点阵)。当用户将手指放在电容阵列正面上时,手指就组成了电容阵列的一个极板,电容阵列的背面是绝缘极板。由于不同区域指纹的脊和谷之间的距离不相等,可以根据两极板之间的电容公式C=ε 0εs/d,使每个单元的电容量随着指纹脊和谷之间的距离的变化而变化,根据每个单元电容量的不同产生不同电压,由此可获得指纹图像。
当前可以将指纹识别模组内置于移动终端屏幕之下用于实现全屏的指纹识别功能,相对于现有的将指纹模组单独固定开孔放置在移动终端正面或者背面的形式,需要扫描的第一区域101的面积是原先需要扫描的第二区域102的面积的几十倍(如图1所示)。全屏指纹要达到正面或者背面开窗指纹同样的分辨率,点阵数量由原来的152*200可能变为(152*6)*(200*12),因此需要扫面的点阵数量变为原来的70多倍,简化的全屏指纹扫描如图2a所示, 其中图中仅画出了TX(驱动)6线和RX(接收)12线,6*12个点阵代表当前全屏指纹需要的点阵个数,其指纹识别驱动芯片对应的扫描信息如图2b所示。因此当前全屏指纹实现方式相对之前固定开窗的正面指纹和背面指纹方案,存在如下两个明显的缺陷。
一、为了达到与原来固定开孔放置在正面或者背面的局部指纹相同的分辨率,全面屏指纹识别驱动芯片的TX需要为原来的6倍,RX需要为原来的12倍,这会大大增加指纹识别驱动芯片的制作成本。
二、由于需要扫描的点阵扩大了几十倍,所以每次扫描功耗增多、扫描点阵所需要的时间相应增加。为实现全屏指纹而导致移动终端额外增加功耗和扫描时间,影响移动终端的续航能力同时影响用户的指纹识别体验。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
本公开实施例提供一种移动终端,如图3a和图3b所示,包括:
在预设指纹检测区域11呈阵列分布的多个指纹识别电极12;在预设指纹检测区域11交叉设置的多条指纹信号驱动线路(TX)和多条指纹信号接收线路(RX),其中,每一指纹识别电极12分别连接一指纹信号驱动线路和一指纹信号接收线路;预设指纹检测区域11包括至少两个划分区域,每一划分区域内交叉设置有第一数目的指纹信号驱动线路和第二数目的指纹信号接收线路;指纹识别驱动芯片13,包括第一数目的第一线路连接端和第二数目的第二线路连接端,其中,每一划分区域内的指纹信号驱动线路分别一一对应的连接至第一线路连接端,每一划分区域内的指纹信号接收线路分别一一对应的连接至第二线路连接端。其中在图3a中,每一指纹信号驱动线路和每一指纹信号接收线路的交叉点处对应于一指纹识别电极12,图中仅做出了示意性表示,并未全部画出。
移动终端的预设指纹检测区域11形成有多个按照阵列排布的指纹识别电极12,其中指纹识别电极12可以为电容式指纹识别电极,当然也可以是其他类型的指纹识别电极,这里的指纹识别电极12可理解为指纹识别传感器。通过设置多个指纹识别电极12可以形成指纹识别阵列,根据指纹识别阵列来采集手指表面的纹路。在预设指纹检测区域11同时设置多条交叉的指纹信号驱动线路和指纹信号接收线路,其中一指纹信号驱动线路与多条指纹信号接收线路交叉,相应的一指纹信号接收线路与多条指纹信号驱动线路交叉,一指纹信号接收线路与一指纹信号驱动线路在交叉处形成交叉点。
其中,每一指纹识别电极12分别与一指纹信号驱动线路和一指纹信号接收线路连接。一指纹识别电极12与对应的指纹信号驱动线路和指纹信号接收线路形成信号传输电路。其中指纹识别电极12在接收到用户手指的触控操作时可以产生电压变化信号,通过与指纹信号驱动线路和指纹信号接收线路形 成的信号传输电路将产生的电压变化信号进行传输。
移动终端的预设指纹检测区域11包括至少两个划分区域,其中各个划分区域内所对应的指纹信号驱动线路的数目相同,所对应的指纹信号接收线路的数目也相同。其中每一划分区域内对应的指纹信号驱动线路为第一数目,每一划分区域内对应的指纹信号接收线路为第二数目。第一数目和第二数目可以相同,也可以不同,需要根据预设指纹检测区域11内指纹信号驱动线路和指纹信号接收线路的数目以及区域划分原则来确定。
移动终端还包括指纹识别驱动芯片13,其中指纹识别驱动芯片13包括第一线路连接端和第二线路连接端,第一线路连接端的数目与每一划分区域内的指纹信号驱动线路的数目相同,第二线路连接端的数目与每一划分区域内的指纹信号接收线路的数目相同。且第一线路连接端与每一划分区域内的指纹信号驱动线路连接,第二线路连接端与每一划分区域内的指纹信号接收线路连接,可以使得至少两个划分区域共用一指纹识别驱动芯片13。由于每一划分区域内的指纹信号驱动线路、指纹识别电极12以及指纹信号接收线路形成信号传输电路,指纹信号驱动线路与指纹识别驱动芯片13的第一线路连接端连接、指纹信号接收线路与指纹识别驱动芯片13的第二线路连接端连接,可以实现指纹识别驱动芯片13通过第一线路连接端和第二线路连接端获取指纹识别电极12所对应的信号,根据指纹识别电极12所对应的信号生成相应的指纹图像。
其中指纹识别驱动芯片13与移动终端的处理器连接,处理器与指纹识别驱动芯片13连接之后,可以获取指纹识别驱动芯片13采集的变化信号,根据变化信号来进行指纹识别处理。
通过上述移动终端可以实现一指纹识别驱动芯片对各划分区域共同控制,使得全屏指纹识别的方案能够减小指纹识别驱动芯片的制作成本,减低指纹识别驱动芯片的扫描范围进而降低移动终端的功耗,可以保证移动终端的续航能力,提升用户的指纹应用体验。
在本公开实施例中,如图3a和图3b所示,移动终端预设指纹检测区域11内划分区域的数目根据预设指纹检测区域11内指纹信号驱动线路和指纹信号接收线路的数目以及指纹识别驱动芯片13来确定,所对应的划分区域的 数目至少为两个。本公开实施例中以预设指纹检测区域11内指纹信号驱动线路的数目为6个,指纹信号接收线路的数目为12个,划分区域的数目为6个为例进行说明。其中每一划分区域内所对应的指纹信号驱动线路的数目为3个,每一划分区域内所对应的指纹信号接收线路的数目为4个,6个划分区域共用一指纹识别驱动芯片13。
在确定划分区域的数目时,需要兼顾识别成功率和功耗,根据实际调试情况去定,每个划分区域内的指纹信号驱动线路/指纹信号接收线路共用一个指纹识别驱动芯片13的第一线路连接端/第二线路连接端。因此每个划分区域内的所需要扫描的点阵数为原来全面屏指纹需要扫描数量的1/6,每个划分区域内的分辨率跟原有全面屏指纹分辨率是一样的。对于指纹识别驱动芯片13来说,第一线路连接端变为原来的1/2,第二线路连接端变为原来的1/3,有利于降低指纹识别驱动芯片13的制作成本,由于更改点阵布局方式之后每次扫描指纹需要扫描点阵的数量变为原来的1/6,使得每一次扫描的扫描速度要更快一些、功耗也会降低。
通过这种划分区域共用指纹识别驱动芯片的方式可以在同样的分辨率下有效的减少所需的第一线路连接端/第二线路连接端的数量。并且由于所需扫描点阵数量的减少可以节省指纹扫描时间加快扫描速度和降低指纹扫描的功耗。
在本公开实施例中,移动终端包括显示面板,指纹识别电极12与显示面板层叠设置,且预设指纹检测区域11对应于显示面板的全部区域。指纹识别电极12与显示面板层叠设置,在指纹识别电极12上设置触控面板,通过用户对触控面板的触控操作,可以使得指纹识别电极12产生变化信号,触控面板可覆盖在显示面板上。其中指纹识别电极12设置于预设指纹检测区域11内,且在预设指纹检测区域11内呈阵列的方式进行排列,预设指纹检测区域11对应于整个显示面板,可以保证用户对指纹识别电极12的触控操作。
在本公开实施例中,指纹信号驱动线路为显示面板的栅线和数据线的其中一个,指纹信号接收线路为显示面板的栅线和数据线中的另一个。每一划分区域内所对应的指纹信号驱动线路为显示面板的栅线或者数据线,指纹信号接收线路为数据线或者栅线,在指纹信号驱动线路为栅线时,则指纹信号 接收线路为数据线,在指纹信号驱动线路为数据线时,则指纹信号接收线路为栅线。
在本公开实施例中,每一划分区域内的按照第一方向的排列次序排列的指纹信号驱动线路,依次连接指纹识别驱动芯片13上按照第二方向的排列次序排列的每一第一线路连接端。每一划分区域内的按照第三方向的排列次序排列的指纹信号接收线路,依次连接指纹识别驱动芯片13上按照第四方向的排列次序排列的每一第二线路连接端。
在每一划分区域内各指纹信号驱动线路按照第一方向依次排列,其中指纹信号驱动线路分别与指纹识别驱动芯片13上的第一线路连接端连接,指纹识别驱动芯片13上的第一线路连接端按照第二方向依次排列,其中第一方向和第二方向平行。每一划分区域内各指纹信号接收线路按照第三方向依次排列,指纹信号接收线路分别与指纹识别驱动芯片13上的第二线路连接端连接,指纹识别驱动芯片13上的第二线路连接端按照第四方向依次排列,其中第三方向与第四方向平行,第一方向与第三方向垂直,第二方向与第四方向垂直。
通过设置预设指纹检测区域11内指纹信号驱动线路和指纹信号接收线路的排列方向和顺序,设置指纹识别驱动芯片13上第一线路连接端和第二线路连接端的排列方向和顺序,可以保证指纹识别驱动芯片13对不同指纹识别电极12的确认,进而识别出发生信号变化的指纹识别电极12,更进一步的还可以根据移动终端上的坐标信息确认出接收用户触控操作的区域位置。
本公开实施例主要是针对全屏指纹识别相对于当前放置在正面或者背面的局部指纹识别,会导致其对应的指纹识别驱动芯片的制作成本增加,功耗变大和扫描时间变长所进行的改进。改进点是只需要采集到用户的指纹图像,并不需要十分关心所采集用户的指纹图像在屏幕的具体位置,并且用户的指纹图像面积相对于屏幕来说是一个比较小的面积,利用这两个特点可以将屏幕进行区域划分。每个划分区域内的指纹信号驱动线路/指纹信号接收线路共用一个指纹识别驱动芯片的第一线路连接端/第二线路连接端。通过这种划分区域共用指纹识别驱动芯片的方式可以在同样的分辨率下有效的减少所需的第一线路连接端/第二线路连接端的数量,降低指纹识别驱动芯片的制作成本,并且由于所需扫描点阵数量的减少可以节省指纹扫描时间加快扫描速度和降 低指纹扫描的功耗。
从另一方面来说,通过进行区域划分,可以使得每个划分区域内的指纹信号驱动线路/指纹信号接收线路共用一个指纹识别驱动芯片的第一线路连接端/第二线路连接端,相对于全屏指纹信号驱动线路/指纹信号接收线路使用一个指纹识别驱动芯片的第一线路连接端/第二线路连接端的情况,可以相对提高每个划分区域内的分辨率,但不需要额外增加指纹识别驱动芯片的第一线路连接端/第二线路连接端的数量,也不会因为分辨率变高而导致每次扫描获取指纹图像的功耗增加和时间变长。
本公开实施例还提供一种指纹识别方法,应用于上述的移动终端,如图4所示,该方法包括:步骤401和402。
步骤401、获取指纹识别驱动芯片根据第一线路连接端和第二线路连接端的信号生成的对应的指纹图像,其中,预设指纹检测区域所包括的至少两个划分区域中的每一划分区域内的指纹信号驱动线路均连接至第一线路连接端,每一划分区域内的指纹信号接收线路均连接至第二线路连接端。
移动终端的处理器与指纹识别驱动芯片连接,在预设指纹检测区域内有呈阵列分布的多个指纹识别电极;同时在预设指纹检测区域内交叉设置多条指纹信号驱动线路和多条指纹信号接收线路,其中每一指纹识别电极分别连接一指纹信号驱动线路和一指纹信号接收线路。
同时预设指纹检测区域内包括至少两个划分区域,每一划分区域内包括第一数目的指纹信号驱动线路和第二数目的指纹信号接收线路;指纹识别驱动芯片包括第一数目的第一线路连接端和第二数目的第二线路连接端,其中每一划分区域内的指纹信号驱动线路分别一一对应的连接至第一线路连接端,每一划分区域内的指纹信号接收线路分别一一对应的连接至第二线路连接端。
由于指纹识别驱动线路、指纹识别接收线路与指纹识别电极连接,指纹识别驱动芯片通过指纹识别驱动线路、指纹识别接收线路、第一线路连接端以及第二线路连接端可以获取指纹识别电极所对应的变化信号,然后根据变化信号生成对应的指纹图像。指纹识别驱动芯片在生成指纹图像之后,将所生成的指纹图像传输至处理器。
步骤402、将获取的指纹图像与预设指纹信息进行比较,根据比较信息 生成指纹识别结果。
移动终端的处理器在获取指纹识别驱动芯片所传输的指纹图像之后,将所获取的指纹图像与存储的预设指纹信息进行比较,判断所获取的指纹图像与预设指纹信息是否匹配,在两者相匹配时,则根据匹配结果生成指纹识别成功信息,在两者不匹配时,则根据不匹配结果生成指纹识别不成功信息。
针对用户在划分区域的交界处进行指纹操作时,由于在不同的划分区域内指纹识别电极所连接的指纹信号驱动线路和指纹信号接收线路不同,此时可以根据所占的划分区域数目生成对应数目的变化信号。
在本公开实施例中,在获取到指纹识别驱动芯片发送的至少两个指纹图像时,还包括:在至少两个指纹图像中确定出面积最大的指纹图像;将所确定面积最大的指纹图像与预设指纹信息进行匹配;若所确定面积最大的指纹图像与预设指纹信息的匹配度大于预设阈值,确定指纹识别成功。
在处理器接收到指纹识别驱动芯片同时发送的至少两个指纹图像之后,可以确定此时用户在划分区域的交界处进行指纹操作,此时需要将接收到的指纹图像进行面积比对,由于在交界区域进行指纹操作时,会出现不同划分区域所占面积不同的情况,因此可以将接收到的指纹图像进行面积比对。在进行面积比对之后,可以在至少两个指纹图像中确定出面积最大的指纹图像,在确定出面积最大的指纹图像之后,将所确定的面积最大的指纹图像与预设指纹信息进行比较,确定两者的匹配度,在两者的匹配度大于预设阈值时,则可以确定用户输入的指纹为预设指纹,此时指纹识别成功。
需要说明的是,针对所接收到的指纹图像的数量不同,则对应的预设阈值有所差别,例如,若所接收到的指纹图像的数量为两个,则对应的预设阈值为50%,若所接收到的指纹图像的数量为四个,则对应的预设阈值为25%。
需要说明的是,针对交界区域接收到指纹输入操作的情况,为了保证交界区域的指纹识别有效性,还可以使得交界区域距离相邻两指纹信号驱动线路和相邻两指纹信号接收线路之间的距离相等,或者使得这两个距离差别尽量减小。
在本公开实施例中,该方法还包括:在移动终端处于亮屏状态且预设指纹检测区域接收到指纹操作之前,显示区域划分信息。
为了保证用户在非交界位置进行指纹操作,在移动终端处于亮屏状态的情况下,且在预设指纹检测区域接收到用户所输入的指纹操作之前,移动终端可以在显示界面显示区域划分信息,这里的区域划分信息可以为在显示界面直接显示区域分界线,这样用户可以通过识别区域分界线来确认交界区域。
在本公开实施例中,显示区域划分信息的步骤具体为:显示区域划分信息,输出提示用户在划分区域的内部进行指纹操作的提示信息。
在移动终端显示区域划分信息的同时,为了更好的进行指纹识别,移动终端可以在显示界面输出提示信息,提示用户在划分区域的内部进行指纹操作,以保证指纹识别效果。
还可以在显示区域划分信息的同时,显示提示用户在每一交界区域均进行指纹输入操作的提示信息,通过接收用户对每一交界区域的指纹输入操作,可以对接收到的指纹信息进行拼接,合成一完整的指纹图像,提高指纹识别的成功率。
在本公开实施例中,在根据比较信息生成指纹识别成功结果后,还包括:根据指纹识别成功结果生成控制指令;根据控制指令对移动终端进行解锁、加密或者支付操作。
在确认指纹识别成功之后,移动终端可以根据指纹识别成功结果生成控制指令,根据控制指令来控制移动终端进行解锁、加密或者支付等操作。例如在移动终端处于锁屏状态下,在指纹识别成功时则直接对移动终端进行解锁使得移动终端处于解锁状态。或者在移动终端处于待支付状态下,在指纹识别成功时则直接进行支付。
本公开实施例还提供一种指纹识别实施方式,如图5所示,包括:步骤501至505。
步骤501、移动终端处于锁屏状态。
步骤502、控制指纹识别驱动芯片对预设指纹检测区域内的划分区域进行扫描。
在扫描过程中,由指纹识别驱动芯片对各划分区域按照预设扫描原则同时进行扫描,在扫描完成后获取指纹图像。
步骤503、将扫描获取的指纹图像与预设指纹信息进行比较。
步骤504、在指纹图像与预设指纹信息相同时,对移动终端进行解锁。
步骤505、在指纹图像与预设指纹信息不同时,保持移动终端的锁屏状态。
通过在预设指纹检测区域设置至少两个划分区域,在每一划分区域设置第一数目的指纹信号驱动线路和第二数目的指纹信号接收线路,通过各划分区域内指纹信号驱动线路和指纹信号接收线路与指纹识别驱动芯片的连接,可以利用指纹识别驱动芯片对各划分区域共同控制,使得全屏指纹识别的方案能够减小指纹识别驱动芯片的制作成本,减低指纹识别驱动芯片的扫描范围进而降低移动终端的功耗,可以保证移动终端的续航能力,提升用户的指纹应用体验。
