为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例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做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。
以下结合附图，详细说明本申请各实施例提供的技术方案。
需要说明的是，本申请所涉及的指纹识别控制方案是应用在具备处理器等功能模块的触控屏或具备触控屏的电子设备，例如：手机、平板电脑、VR、 AR、穿戴设备，等其他需要触摸的设备。
在本申请中，参照图1(a)所示，为本申请实施例提供的指纹识别控制方法的流程示意图之一，该方法主要包括以下步骤：
步骤11a：在检测到指纹识别指令时，触发指纹识别模块开启，采集第一指纹信息。
其中，所涉及的指纹识别指令可以为通过对触控面板实施触控操作而触发的指令，也可以为通过声控触发生成的指令或是其他终端发送的指令。
步骤12a：查找预存的指纹信息列表中是否存在与所述第一指纹信息相匹配的第二指纹信息，若存在，则确定指纹识别成功。
从而，可以在显示区域任意位置实现屏下指纹识别，提升指纹识别的灵活性便捷性，节省屏幕功耗，易实现全面屏的屏下指纹识别。
参照图1(b)所示，为本申请实施例提供的指纹识别控制方法的流程示意图之二，该方法主要包括以下步骤：
步骤11b：在检测到触控操作时，确定所述触控操作对应的触控位置。
其中，所述触控位置位于触控面板的显示区域。在本申请中，所涉及的触控操作，可以理解为是手指按压触控屏幕中对应显示区域的任一位置处的操作。一种实现方式，触控面板的触控膜层可以根据传感器采集到的触控信号，确定用户手指按压对应的触控位置。
进一步，为了更为精准的实现指纹信息的采集，参照图2(a)所示，步骤11b具体执行为：
步骤111：检测所述触控操作的按压属性。
步骤112：当所述按压力属性满足预设条件时，将实施有所述触控操作的区域确定为所述触控操作对应的触控位置。
在本申请中，针对触控操作而言，所述按压属性可以包括：按压力度、按压时间、按压方式等。其中，按压方式可以理解为接触按压或非接触按压(即不接触触控面板而实现的体感按压)，或者，按压之后发生一定方向的旋 转按压，或者，滑动操作等。
例如，检测到触控面板的显示区域的任一位置被实施有触控操作时，检测该触控操作的按压力度，当按压力度大于第一阈值时，则将实施该触控操作的区域确定为触控操作对应的触控位置。
再如，检测到触控面板的显示区域的任一位置被实施有触控操作时，检测该触控操作的按压时间，当按压时间大于第二阈值时，则将实施该触控操作的区域确定为触控操作对应的触控位置。
再如，检测到触控面板的显示区域的任一位置被实施有触控操作时，检测该触控操作的按压力度以及按压时间，当按压力度大于第一阈值且按压时间大于第二阈值时，则将实施该触控操作的区域确定为触控操作对应的触控位置。
步骤12b：触发所述触控位置对应的指纹识别模块开启，采集第一指纹信息。
在本申请中，由于指纹识别模块所对应的指纹识别膜层是设置在整个触控膜层表面的，那么，在确定触控操作对应的触控位置后，无需开启整个指纹识别膜层对应的指纹识别模块，只需开启与触控位置相对应的区域处的指纹识别模块，以对实施该触控操作的用户的指纹进行采集。
具体地，在确定触控操作对应的触控位置之后，可根据确定的触控位置，进一步确定该触控位置对应的指纹识别模块，之后，触发触控位置对应的指纹识别模块开启，采集第一指纹信息。
其中，在本申请中，采集第一指纹信息的方式为光学指纹识别，相应地，可以是红外传感元件或是其他光学传感元件。那么，在本实施例中，当确定触控位置之后触发指纹识别模块开启，采集第一指纹信息，这一过程可视为触控面板始终呈亮屏状态；通过触控面板的显示膜层供给的光源，采集触控位置处的指纹纹路图像得到第一指纹信息。
可选地，在本申请中，当前触控面板处于息屏状态，则在确定所述触控 操作对应的触控位置之后，采集第一指纹信息之前，所述方法还包括：控制所述触控位置对应的发光子像素点亮。从而，将设置在触控膜层下方的发光子像素局部点亮，以用来辅助指纹识别操作提供光源，节省屏幕功耗；而且，还可以通过这种唤醒方式将指纹识别区域凸显给用户，便于实现指纹按压识别。
步骤13b：查找预存的指纹信息列表中是否存在与所述第一指纹信息相匹配的第二指纹信息，若存在，则确定指纹识别成功。
在采集第一指纹信息之后，将该第一指纹信息与预存的指纹信息列表中的第二指纹信息进行比对，以进行指纹识别。
其中，预存的指纹信息列表中的第二指纹信息是在设置过程中通过触控操作添加的，其中，触控操作包括单指触控操作或多指触控操作。
举例说明，这里的指纹信息列表相当于预先搜集的指纹形成的指纹库，该指纹库中包含有多个第二指纹信息，所述第二指纹信息可以为同一用户的多种第二指纹信息，例如，用户A的屏幕解锁指纹信息-左手大拇指的指纹信息、交易验证指纹信息-右手食指的指纹信息、登录验证指纹信息-左手食指的指纹信息等。
可选地，在本申请中，触控位置包括至少一个被实施触控操作的独立区域；第一指纹信息为对应至少一个独立区域的指纹识别模块同时采集的至少一个指纹信息。
可选地，第一指纹信息包含同时采集的多个指纹信息；相应地，执行步骤13b中：查找预存的指纹信息列表中是否存在与所述第一指纹信息相匹配的第二指纹信息时，具体包括：
步骤131：遍历预存的指纹信息列表中的第二指纹信息。
步骤132：查找第二指纹信息中包含的指纹信息是否与所述第一指纹信息中包含的指纹信息相同。
例如，第一指纹信息为用户A的左手拇指与用户B的右手拇指同时触控 按压触控面板时采集到的，那么，在进行指纹信息比对时，需要查找预存的指纹信息列表中是否存在同时包含用户A的左手拇指的指纹信息和用户B的右手拇指的指纹信息的第二指纹信息，若存在，则指纹识别成功，否则，指纹识别失败。
由此，通过本申请技术方案，能够通过按压触控面板的显示区域的任意位置实现对相应指纹识别模块的开启，不需要按压特定区域，也无需开启整个指纹识别膜层中的指纹识别模块，节省屏幕功耗，易实现全面屏的屏下指纹识别，且可以在显示区域任意位置实现屏下指纹识别，提升指纹识别的灵活性便捷性。
其实，在本申请中，若显示屏幕为亮屏状态下，则指纹识别成功之后，所述方法还包括：解锁所述触控面板的屏幕，或，交易验证通过，或登录验证通过。若显示屏幕为暗屏状态下，则在局部点亮发光子像素的情况下指纹识别成功后，所述方法还包括：触发点亮所述触控面板的显示区域，和/或，解锁所述触控面板的屏幕，或，交易验证通过，或登录验证通过。
在本申请中，与上述指纹识别控制方法属于同一发明构思，还提供了一种触控面板，参照图3所示，该触控面板主要包括：
确定模块31，用于在检测到触控操作时，确定所述触控操作对应的触控位置，其中，所述触控位置位于触控面板的显示区域；
采集模块32，触发所述触控位置对应的指纹识别模块开启，采集第一指纹信息；
处理模块33，查找预存的指纹信息列表中是否存在与所述第一指纹信息相匹配的第二指纹信息，若存在，则确定指纹识别成功。
此外，该触控面板还包括至少一个控制显示的其他模块。
可选地，在本申请中，还包括：
控制模块，用于当前触控面板处于息屏状态时，确定模块确定所述触控操作对应的触控位置之后，采集模块采集第一指纹信息之前，控制所述触控 位置对应的发光子像素点亮。
可选地，在本申请中，所述处理模块在指纹识别成功之后，还用于：
触发点亮所述触控面板的显示区域，和/或，解锁所述触控面板的屏幕。
可选地，在本申请中，所述确定模块，具体用于：
检测所述触控操作的按压属性；
当所述按压属性满足预设条件时，将实施所述触控操作的区域确定为所述触控操作对应的触控位置。
可选地，所述触控位置包括至少一个被实施触控操作的独立区域；所述第一指纹信息为对应所述至少一个独立区域的指纹识别模块同时采集的至少一个指纹信息。
可选地，所述第一指纹信息包含同时采集的多个指纹信息；
所述处理模块在查找预存的指纹信息列表中是否存在与所述第一指纹信息相匹配的第二指纹信息时，具体用于：
遍历所述预存的指纹信息列表中的第二指纹信息；
查找所述第二指纹信息中包含的指纹信息是否与所述第一指纹信息中包含的指纹信息相同。
可选地，所述预存的指纹信息列表中的第二指纹信息是在设置过程中通过触控操作添加的，其中，所述触控操作包括单指触控操作或多指触控操作。
在本申请中，还提供了一种触控面板，具体参照图4所示的触控面板硬件结构示意图，该触控面板主要包括：
触控膜层41，设置在所述触控膜层41的入光面一侧的指纹识别膜层42；所述指纹识别膜层42也可以设置在所述触控膜层41的非入光面一侧；
其中，所述指纹识别膜层42在触控面板上的正投影与所述触控膜层41在触控面板上的正投影重合，所述指纹识别膜层中包含呈阵列排布的多个指纹识别模块。需要说明的是，本申请所涉及的指纹识别膜层42以及触控膜层41都是图案化的，两者的正投影至少部分重合，其实是指指纹识别膜层42 设置在触控膜层41的整个表面，这里的“设置”仅是一种位置关系，并不代表两者必须直接接触，其实，两者之间还可以设置中间膜层，具体膜层关系可根据实际的膜层设计进行设置。
此外，该触控面板还包括：处理芯片以及显示模组、封装盖板等部件。
通过上述技术方案，指纹识别膜层设置在触控膜层的入光面一侧的整个表面处，从而，可以保证在触控面板的显示区域的任意位置处都可以实现指纹识别，提升指纹识别的灵活性便捷性。
同时，本申请还提出了一种显示装置，该显示装置包括所述的触控面板。此外，该显示装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪、智能穿戴设备等任何具有显示功能的产品或部件。对于该显示装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本申请的限制。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
