技术领域
本申请涉及显示技术领域，尤其涉及一种指纹识别控制方法及触控面板、显示装置。
背景技术
现有技术中，将指纹识别功能集成在触控面板中以提升用户的使用体验，已经成为当今的技术潮流。

具体实施方式
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。
参照图1所示，为本申请实施例提供的触控面板的结构示意图，需要说明的是，本申请并不对触控面板的类型进行限定，可以是OLED触控面板或是微LED触控面板，此外，还可以是LCD触控面板。以下主要以OLED触控面板为例进行说明。该触控面板主要包括：
基底11，位于所述基底11一侧的触控膜层12，设置在对应所述触控膜层12预设区域的图像处理模组13，所述图像处理模组13包括用于分时执行指纹识别和图像拍摄的第一模块131以及第二模块132。
其中，对应所述触控膜层预设区域可以是位于触控膜层上，也可以是图像处理模组的正投影位于触控膜层预设区域。在本申请中，图像处理模组不限于设置在触控膜层上，还可以设置在其他膜层中，而本申请主要以设置在触控膜层为例进行说明。
其中，本申请所涉及的基底11可以为刚性基底或是柔性基底。触控膜层12的图案也并不限定，可以为能够实现触控功能的任意图案电极。这里所涉及的预设区域，是指位于触控膜层上，对应触控面板的任一可设置图像处理模组的显示区域。优选可以设置在对应触控面板的边缘区域或是对应触控面板的显示区域的中下方。
所述图像处理模组可以在不同时段，分别独立执行指纹识别操作和图像拍摄操作；例如，在第一时段，可实现指纹识别操作；在与第一时段并无交叉的第二时段，实现图像拍摄操作。由此，在本申请中，设置在触控膜层预设区域的图像处理模组兼容了指纹识别功能以及图像拍摄功能。由于图像处理模组设置在触控膜层下方，且可以设置在触控膜层所在显示区域，不需要占据触控面板正面的非显示区域，这样，无需额外设置边框来容纳外设的指纹识别部件以及摄像头部件，从而，可以有效实现触控面板的全面屏设计。而且，考虑到本申请中图像处理模组兼具指纹识别以及图像拍摄功能，可减小外设部件占据显示区域的缺陷，进一步提升全面屏设计的有效性。另外， 将指纹识别功能与图像拍摄功能集成在同一个区域，不仅提升部件紧凑程度，减小占屏比，还可以优化制作工艺。
可选地，在本申请中，图像处理模组可以是一体化设计，即各个模块集成在一起；也可以是组装设计，即各个模块分离设计。具体可以参照以下两种触控面板结构。
结构1：
参照图2(a)所示，该触控面板还包括：夹设在基底11与触控膜层12之间的显示膜层14；所述第一模块131与所述第二模块132集成在一起，且设置在所述显示膜层14中靠近所述基底11的一侧。
可选地，在该结构中，所述第一模块131为分时采集指纹识别模式下指纹图像和拍摄模式下场景图像的图像采集模块；所述第二模块132为分时处理所述指纹图像和所述场景图像的图像处理模块。
具体而言，在指纹识别模式下，第一模块131采集指纹图像，并将指纹图像发送给第二模块132进行比对识别。在拍摄模式下，第一模块131采集场景图像，并将场景图像发送给第二模块132进行处理，具体的处理操作可以包括美图、显示等。
那么，在该结构1中，图像处理模组的具体硬件结构包括：呈阵列排布的图像传感元件，以及处理器。其处理器中集成有包含各种算法的模块，以实现对图像传感元件采集的图像信息的识别、比对、处理等。
该结构1采用集成的方式将指纹识别功能和图像拍摄功能兼容在一个模组中，从而，实现结构部件的紧凑设置；同时，简化屏下部件的结构。
结构2：
参照图2(b)所示，该触控面板还包括：夹设在基底11与触控膜层12之间的显示膜层14；所述第一模块131与所述第二模块132分离设置，且所述第一模块131设置在所述显示膜层14与所述触控膜层12之间，所述第二模块132设置在所述显示膜层14中靠近所述基底11的一侧。
可选地，所述第一模块131为在指纹识别模式下执行指纹识别的指纹识别模块；所述第二模块132为在拍摄模式下执行图像拍摄的拍摄模块。
具体而言，在指纹识别模式下，第一模块131采集指纹信息，并对指纹信息进行比对识别。在拍摄模式下，第二模块132采集场景图像，并对场景图像进行处理，具体的处理操作可以包括美图、显示等。
那么，在该结构2中，图像处理模组的具体硬件结构可以包括：位于第一模块131中的呈阵列排布的图像传感元件以及指纹识别处理器；位于第二模块132中呈阵列排布的图像传感元件以及图像处理器。或者，图像处理模组的具体硬件结构包括：位于第一模块131中的超声波发射器以及接收器，指纹识别处理器；位于第一模块132中呈阵列排布的图像传感元件以及图像处理器。
该结构2采用分离设置的方式将指纹识别功能和图像拍摄功能兼容在一个模组中，且第一模块所占据位置在基底上的正投影与第二模块所占据位置在基底上的正投影重合，从而，实现结构部件的紧凑设置；同时，简化屏下部件的结构。
需要说明的是，在上述结构1和结构2中，显示膜层14是图案化的，因此，并不会对位于下面的图像处理模组13造成遮挡；同时，可以对结构2中的第一模块也进行类似的图案化设计，使得第一模块中的图案在基底11上的正投影与显示膜层14中的图案在基底上的正投影的重合面积最少。而且，在本申请示意图中，仅示出了主要膜层结构关系，其实，在显示膜层与触控膜层以及其他相邻膜层之间，还可以设置有至少一个中间膜层。例如，位于显示膜层与触控膜层之间还可以设置有薄膜封装层等，本申请并未示出。
同时，本申请还提供了一种显示装置，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。
针对上述涉及的显示装置，本申请还提供了一种使用上述显示装置进行指纹识别控制的方法。
参照图3所示，为本申请提供的指纹识别控制方法的流程示意图，该方法主要包括：
步骤31：在检测到显示装置中对应触控膜层预设区域的位置实施有满足预设条件的触控操作时，采集对应所述触控操作的第一指纹信息。
其中，所述预设区域设置有用于分时执行指纹识别和图像拍摄的图像处理模组。
这里的显示装置，可以理解为封装有显示模组的显示装置成品，例如，手机或是平板电脑。其实，该手机一直处于对预设区域的监控状态，当检测到该预设区域的触控膜层被触控按压且按压程度满足预设条件时，触发图像处理模组开启，采集触控膜层被按压位置处的第一指纹信息。
可选地，所述预设条件至少包括以下之一：所述触控操作实施的按压时间大于第一阈值；所述触控操作实施的按压力度大于第二阈值。
可选地，在本申请中，采集对应所述触控操作的第一指纹信息，具体可以包括以下两种执行方式：
方式1，图像处理模组中用于实现指纹识别功能的模块为超声波模块。
具体地，触发所述预设区域的图像处理模组开启，采用超声波指纹识别方式，从实施触控操作的预设区域采集得到第一指纹信息。
该方式并不关心显示膜层是否为点亮状态，只要有超声波发送器以及接收器即可实现对预设区域处的指纹信息采集。
方式2，图像处理模组中用于实现指纹识别功能的模块为光学传感模块。
具体地，触发所述预设区域的图像处理模组开启，同时，触发对应所述预设区域的发光子像素点亮，从而，为光学传感元件提供光源，以便于采用光学指纹识别方式，从实施触控操作的预设区域采集得到第一指纹信息。
其实，图像处理模组中用于实现指纹识别功能的模块并不限定上述两种，还可以为电容式指纹识别模块或压力传感式指纹识别模块。
步骤32：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。
需要说明的是，在本申请中，所采集到的第一指纹信息中，至少包含一个手指的指纹。相应的，第二指纹信息也至少包含一个手指的指纹。其中，第二指纹信息可以是预先存储在预存的指纹信息列表中的指纹信息，一般在进行指纹设置时采集保存。举例说明，当前采集到的第一指纹信息为用户的左手拇指与右手拇指同时按压预设区域时采集到的指纹信息，这时的指纹信息就是左手拇指的指纹信息与右手拇指的指纹信息的组合；在进行查找比对时，只有查找到相同的指纹信息组合，才确定指纹识别成功。
其实，指纹识别可以作为解锁验证、登录验证或者交易验证等。通过本申请中的屏下指纹识别以及拍摄功能的集成，可提升用户体验。
可选地，在本申请中，除了能够实现指纹识别，该方法还包括：
在接收到摄像指令时，触发预设区域的图像处理模组开启，并采集当前拍摄场景下的图像信息。
具体地，当图像处理模组中第一模块与第二模块集成在一起时，触发开启第一模块和第二模块，利用第一模块采集当前拍摄场景下的图像信息。当图像处理模组中第一模块与第二模块分离设置时，仅触发开启作为拍摄模块使用的第二模块，利用第二模块采集当前拍摄场景下的图像信息。
触发所述显示装置中对应触控膜层预设区域以外区域的发光子像素点亮，并显示所述图像处理模组采集到的图像信息对应的图像内容。
在本申请中，设置在触控膜层预设区域的图像处理模组兼容了指纹识别功能以及图像拍摄功能。由于图像处理模组设置在触控膜层下方，且可以设置在触控膜层所在显示区域，不需要占据触控面板正面的非显示区域，这样，无需额外设置边框来容纳外设的指纹识别部件以及摄像头部件，从而，可以 有效实现触控面板的全面屏设计。而且，考虑到本申请中图像处理模组兼具指纹识别以及图像拍摄功能，可减小外设部件占据显示区域的缺陷，进一步提升全面屏设计的有效性。另外，将指纹识别功能与图像拍摄功能集成在同一个区域，不仅提升部件紧凑程度，减小占屏比，还可以优化制作工艺。
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。
