Description

一种屏幕识别指纹的方法及终端
本申请要求于2015年4月24日提交中国专利局、申请号为201510200925.5、发明名称为“一种屏幕识别指纹的方法及终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域

背景技术
随着终端技术的不断发展，现在很多终端具备有指纹识别的功能。大部分终端使用面板上的某个按键区域(如：Home键、背部按键)进行指纹识别。例如：(1)终端中的指纹传感器被放置在Home键中，用于指纹信息的记录与识别，Home键传感器表面由激光切割的蓝宝石水晶制成，能够实现精确聚焦指纹信息，保护传感器的作用，而传感器按钮周围的不锈钢环可以监测指纹信息，激活传感器和改善信噪比。当指纹传感器读取到指纹信息时，终端查找相同指纹进行解锁。(2)指纹传感器设置于终端的后盖中，当检测到用户按压终端的后盖的指纹传感器，指纹传感器可以记录并识别指纹信息。另外，指纹识别区域与后壳之间的金属环可以用于触发指纹传感器。但是，在现有技术方案中，如果终端同时设置了密码解锁和指纹识别，用户不仅需要操作屏幕解锁密码，而且需要操作按键验证指纹信息，降低了用户的使用体验，并且如果使用整个屏幕进行解锁密码或者验证指纹信息，增加了终端的功耗。

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2是本发明实施例提供的一种屏幕的结构示意图；
图3是本发明实施例提供的另一种屏幕的结构示意图；
图4是本发明提出的一种屏幕识别指纹的方法的第二实施例的流程图；

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
请参考图1，图1是本发明提出的一种屏幕识别指纹的方法的第一实施例的流程图。如图所示，本发明实施例中的方法包括：
S101，接收用户输入的针对所述多个指纹识别分区的选择指令。
S102，根据所述选择指令，从所述多个指纹识别分区中选择至少一个指纹识别分区进行组合得到独立识别区域。
例如：如图2所示，可以按照4行5列的划分方式将屏幕分成20个指纹识别分区，可以选择20个指纹识别分区中的任何一个指纹识别分区作为独立识别区域，该独立识别区域作为识别指纹信息的唯一位置，其他指纹识别分区不工作；可以选择如图2所示的6、7、10、11分别对应的指纹识别分区进行组合得到独立识别区域，其他指纹识别分区不工作；可以选择全部的20个指纹识别分区进行组合得到独立识别区域。
S103，当所述用户的手指接触到所述屏幕中的所述独立识别区域时，通过所述独立识别区域对所述用户的指纹进行识别。
具体实现中，可以通过所述独立识别区域获取所述用户的指纹验证信息；确定所述指纹验证信息是否与预设的指纹模板信息相同；若所述指纹验证信息与所述预设的指纹模板信息相同，则进入终端的操作界面。
可选的，在通过所述独立识别区域对所述用户的指纹进行识别之前，可以预先获取所述用户的指纹模板信息，并将所述用户的指纹模板信息存入终端的指纹存储区。
可选的，如图3(1)所示，所述屏幕包括电容式指纹识别层、触摸板层以及LED(Light-Emitting Diode，发光二级管)显示层，所述LED显示层位于所述屏幕中的最下层，所述触摸板层位于所述屏幕中的最上层，所述电容式指纹识别层位于所述触摸板层与所述LED显示层之间。
具体实现中，可以根据指纹的脊和谷与指纹识别层中的电容感应颗粒形成的电容值大小不同，分别判断指纹的脊和谷的位置从而获取指纹信息。进一步的，可以预先对屏幕中每个像素点上的电容感应颗粒进行充电，使电容感应颗粒达到预设阈值，当用户手指接触到屏幕时，由于电容值与距离的关系，在脊和谷的位置形成不同的电容值，然后通过放电电流进行放电，因为脊和谷所对应的电容值不同，脊和谷对应的像素点的放电速度也不同，脊对应的像素点放电慢，谷对应的像素点放电速度快。因此通过脊和谷对应的像素点的充电与放电，可以获取用户的指纹信息。
可选的，如图3(2)所示，所述屏幕包括射频式指纹识别层、触摸板层以及LED显示层，所述射频式指纹识别层位于所述屏幕中的最下层，所述触摸板层位于所述屏幕中的最上层，所述LED显示层位于所述触摸板层与所述射频式指纹识别层之间。
具体实现中，当光线照射到压有指纹的触摸板层的表面时，通过CCD(Charge Coupled Device，电荷耦合器件)吸收反射光从而获取指纹信息。进一步的，由于触摸板层上的指纹的脊和谷的深度不同以及皮肤与触摸板层之间的油脂和水分，光线经过触摸板层照射到指纹的谷的位置发生全反射，而照射到指纹的脊的位置不能发生全反射，一部分光线被触摸板层吸收或者漫反射到其他地方，因此在CCD上形成指纹信息。
在本发明实施例中，首先接收用户输入的针对多个指纹识别分区的选择指令；然后根据选择指令，从多个指纹识别分区中选择至少一个指纹识别分区进 行组合得到独立识别区域；最后当用户的手指接触到屏幕中的独立识别区域时，通过独立识别区域对用户的指纹进行识别，从而降低了终端的功耗。
请参考图4，图4是本发明提出的一种屏幕识别指纹的方法的第二实施例的流程图。如图所示，本发明实施例中的方法包括：
S401，接收所述用户输入的模式切换指令。
S402，根据所述模式切换指令，将所述屏幕的显示模式切换为分区选择模式，以使所述用户在所述分区选择模式下对所述多个指纹识别分区进行选择。
S403，接收用户输入的针对所述多个指纹识别分区的选择指令。
S404，根据所述选择指令，从所述多个指纹识别分区中选择至少一个指纹识别分区进行组合得到独立识别区域。
例如：如图2所示，可以按照4行5列的划分方式将屏幕分成20个指纹识别分区，可以选择20个指纹识别分区中的任何一个指纹识别分区作为独立识别区域，该独立识别区域作为识别指纹信息的唯一位置，其他指纹识别分区不工作；可以选择如图2所示的6、7、10、11分别对应的指纹识别分区进行组合得到独立识别区域，其他指纹识别分区不工作；可以选择全部的20个指纹识别分区进行组合得到独立识别区域。
S405，当所述用户的手指接触到所述屏幕中的所述独立识别区域时，通过所述独立识别区域对所述用户的指纹进行识别。
具体实现中，可以通过所述独立识别区域获取所述用户的指纹验证信息；确定所述指纹验证信息是否与预设的指纹模板信息相同；若所述指纹验证信息与所述预设的指纹模板信息相同，则进入终端的操作界面。
可选的，在通过所述独立识别区域对所述用户的指纹进行识别之前，可以预先获取所述用户的指纹模板信息，并将所述用户的指纹模板信息存入终端的指纹存储区。
可选的，如图3(1)所示，所述屏幕包括电容式指纹识别层、触摸板层以及LED显示层，所述LED显示层位于所述屏幕中的最下层，所述触摸板层 位于所述屏幕中的最上层，所述电容式指纹识别层位于所述触摸板层与所述LED显示层之间。
具体实现中，可以根据指纹的脊和谷与指纹识别层中的电容感应颗粒形成的电容值大小不同，分别判断指纹的脊和谷的位置从而获取指纹信息。进一步的，可以预先对屏幕中每个像素点上的电容感应颗粒进行充电，使电容感应颗粒达到预设阈值，当用户手指接触到屏幕时，由于电容值与距离的关系，在脊和谷的位置形成不同的电容值，然后通过放电电流进行放电，因为脊和谷所对应的电容值不同，脊和谷对应的像素点的放电速度也不同，脊对应的像素点放电慢，谷对应的像素点放电速度快。因此通过脊和谷对应的像素点的充电与放电，可以获取用户的指纹信息。
可选的，如图3(2)所示，所述屏幕包括射频式指纹识别层、触摸板层以及LED显示层，所述射频式指纹识别层位于所述屏幕中的最下层，所述触摸板层位于所述屏幕中的最上层，所述LED显示层位于所述触摸板层与所述射频式指纹识别层之间。
具体实现中，当光线照射到压有指纹的触摸板层的表面时，通过CCD吸收反射光从而获取指纹信息。进一步的，由于触摸板层上的指纹的脊和谷的深度不同以及皮肤与触摸板层之间的油脂和水分，光线经过触摸板层照射到指纹的谷的位置发生全反射，而照射到指纹的脊的位置不能发生全反射，一部分光线被触摸板层吸收或者漫反射到其他地方，因此在CCD上形成指纹信息。
在本发明实施例中，首先接收用户输入的针对多个指纹识别分区的选择指令；然后根据选择指令，从多个指纹识别分区中选择至少一个指纹识别分区进行组合得到独立识别区域；最后当用户的手指接触到屏幕中的独立识别区域时，通过独立识别区域对用户的指纹进行识别，从而降低了终端的功耗。
