指纹识别技术常常应用于手机、平板电脑等智能终端的显示屏中。为了给用户带来了极致的视觉感受和良好的使用体验，全面屏设计为当下智能终端的主流设计。为了实现全面屏设计，通常将指纹识别组件设置在手机底部的非显示区域，即手机底部的黑色边框之内。
现有技术中，为了提高指纹信号强度，指纹识别组件需要一个外置光源进行补充工作，而该外置光源的放置位置会直接影响到指纹图像的信号强度与模组整体尺寸。目前，现有的一种LCD(Liquid Crystal Display，简称LCD)屏下指纹识别模组，如图1和图2所示，该LCD屏下指纹识别模组3中将光源2集成在指纹识别模组3内，光源2与指纹识别模组3集成为一体，指纹识别时，光源2透过指纹识别模组3上方液晶显示组件与手机底部的黑色遮挡物(即非显示区域)打到指纹识别区域的手指上，使得手指被点亮后，光源携带指纹图像信息，透过指纹识别模组3上方的液晶显示组件，传导至指纹识别模组3件，被指纹识别模组3接受，并进行图像处理以及指纹识别工作。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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。
为了提高指纹信号强度，指纹识别组件需要一个外置光源进行补充工作，而该外置光源的放置位置会直接影响到指纹图像的信号强度与模组整体尺寸，目前，现有的一种LCD屏下指纹识别模组3，如图1和图2所示，该指纹识别方案中将光源2集成在指纹识别模组3内，光源2与指纹识别模组3集成为一体化结构，指纹识别时，光源2透过指纹识别模组3上方液晶显示组件与手机底部的黑色遮挡物(即非显示区域1103)打到指纹识别区域1105的手指上，使得手指被点亮后，光源2发出的光源携带指纹图像信息，透过指纹识别模组3上方的液晶显示组件，传导至指纹识别模组3件，被指纹识别模组3接受，并进行图像处理以及指纹识别工作。但是，上述LCD屏下指纹识别模组3中，为了提高指纹信号强度，需要对光源2的放置位置进行改变，然而，上述LCD屏下指纹识别模组3由于将光源2集成在指纹识别模组3内，且距离显示模组1的指纹探测区域的手指较远，同时受限于整体集成模组结构的尺寸，该模组会占用较宽的电子装置的区域，不利于灵活改变模组及光源2的位置，因此，如果改变光源的放置位置，将必然直接影响整个指纹识别模组3的尺寸，除此之外，由于将光源2集成在指纹识别模组3内将导致光源2到达指纹识别区手指所处位置的距离较难缩短，进而使得指纹信号强度较难得到提升。为了缩短光源2到达指纹识别区手指所处位置的距离，来提升指纹信号强度，本发明实施例提供了一种指纹识别组件、光学指纹显示模组及电子装置。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
实施例一
图3是本发明实施例一提供的一种指纹识别组件的结构示意图。
如图3所示，本实施例提供一种指纹识别组件，应用于具有显示模组1的电子装置，显示模组1至少包括显示面板12、以及位于显示面板12上的显示盖板11，指纹识别组件包括：位于显示面板12之下的指纹识别模组3、 以及光源2，显示盖板11上设有用于容纳光源2的容纳空间1101，以使光源2设在指纹识别模组3之上，容纳空间1101用于缩短光源2与显示模组1上的指纹识别区域1105的距离。
其中，本实施例中，光源2用于向显示模组1上的指纹识别区域1105发射照射光，照射光在照射到指纹识别区域1105的手指时形成反射光，并透过指纹识别模组3上方的显示模组1传输至指纹识别模组3，进而提升指纹识别强度。
需要说明的是，本实施例中，光源2为指纹识别时，对指纹识别模组3内的检测光源起到一定的补充作用，因此，光源2的设置并不会对指纹识别模组3内的检测光源起到干扰的作用。本实施例中仅对光源2的设置位置作进一步改进，对指纹识别模组3内的检测光源在本实施例中不再做进一步阐述。
其中，本实施例中，如图3所示，指纹识别模组3位于显示面板12的下方，通过在显示盖板11上设有容纳光源2的容纳空间1101，使得光源2位于容纳空间1101内且光源2位于指纹识别模组3的上方，本实施例相较于现有的LCD屏下指纹识别模组3将光源2从指纹识别模组3内释放出来，在一定程度上减小了现有的LCD屏下指纹识别模组3中指纹识别模组3集成光源后的宽度，使得光源2位置的改变不会对指纹模组的尺寸造成影响，而且可以灵活改变光源2的位置，通过在显示盖板11上开设用于容纳光源2的容纳空间1101，使得光源2位于指纹模组的上方，进一步相较于现有的LCD屏下指纹识别模组3，缩短了光源2距离显示模组1的垂直距离，而本实施例中的光源2的水平位置可以在一定范围内自由调节，因此，本实施例通过容纳空间1101的设置，能够缩短光源2与显示模组1上的指纹识别区域1105的距离，进而提升指纹信号强度。
需要说明的是，本实施例中，光源2的水平位置可以在一定范围内自由调节，具体可以通过将容纳空间1101水平开口长度大于光源2的水平长度，能够使得在光源2能够在水平方向上在容纳空间1101内自由放置。
其中，本实施例中，光源2可以靠近显示模组1的指纹识别区域1105设置，以缩短光源2与指纹探测区域的距离，进而提升指纹信号强度。需要说明的是，本实施例中，光源2的设置位置相较于现有的LCD屏下指纹识别模组3不受限于指纹识别模组3的位置。
其中，本实施例中，容纳空间1101可以为一端开口的腔体结构，可以为半敞开式结构或其他结构，即本实施例中，容纳空间1101包括但不仅限于为一端开口的腔体结构。在本实施例中，容纳空间1101的顶部可以与光源2的顶部呈平行状态，也可以与光源2的顶部呈一定夹角。需要说明的是，在本实施例，对于容纳空间1101的结构并不作进一步限定，即在本实施例中，只需保证光源2能够放置在容纳空间1101内，且通过显示盖板11上容纳空间1101的结构能够缩短光源2与指纹识别区域1105手指的距离即可。
需要说明的是，本实施例中，在显示盖板11上设置腔体结构的方式可以通过激光加工、也可以通过机械雕刻加工、刻蚀工艺或者光刻工艺等方式进行实现，其中本实施例中在显示盖板11上采用何种工艺方式设置腔体结构可以根据容纳空间1101所需的尺寸及成本的考量，在本实施例中不再对其具体采用何种方式作进一步限定。
其中，本实施例中，显示盖板11可以为玻璃盖板，也可以为采用透明材料制备而成的盖板结构，如聚甲基丙烯酸甲酯(polymethyl methacrylate，简称：PMMA)制备而成的盖板结构，即本实施例中，显示盖板11包括但不仅限于玻璃盖板。
本发明提供一种指纹识别组件、光学指纹显示模组及电子装置，指纹识别组件，应用于具有显示模组1的电子装置，显示模组1至少包括显示面板12、以及位于显示面板12上的显示盖板11，指纹识别组件包括：位于显示面板12之下的指纹识别模组3、以及光源2，显示盖板11上设有用于容纳光源2的容纳空间1101，通过在显示盖板11上设置容纳空间1101，以使光源2从指纹识别模组3内释放出来，并设在指纹识别模组3之上，一方面使得光源2位置的改变不会对指纹识别模组3的尺寸造成影响，另一方面，相较于现有技术中光源2集成在指纹识别模组3内，由于光源2设在容纳空间1101内，并位于指纹识别模组3之上，能够有效缩短光源2距离显示模组1的垂直距离，而光源2通过容纳空间1101可在显示模组1的一定范围内自由水平放置，根据光源2的放置可在一定范围内任意设置指纹识别区域1105所处的位置，因此，光源2从指纹识别模组3内释放出来，通过容纳空间1101可以缩短光源2与显示模组1上的指纹识别区域1105的距离，进而提升指纹信号强度。本发明实现了缩短光源2与显示模组1上的指纹识别区域1105的距 离的目的，解决了现有LCD屏下指纹识别方案将光源2集成在指纹识别模组3内，以致较难缩短光源2与指纹识别区手指的距离的问题。
实施例二
进一步的，在上述实施例一的基础上，如图3所示，本实施例中，显示盖板11至少设有非显示区域1103，容纳空间1101位于非显示区域1103，光源2和指纹识别模组3均设在非显示区域1103内。
其中，本实施例中，光源2可以在非显示区域1103内任意设置，即光源2可以通过容纳空间1101设置在非显示区域1103的任意方位，其中任意方位包括非显示区域1103的侧壁、顶部或底部。
进一步的，本实施例中，容纳空间1101为设在非显示区域1103朝向指纹识别模组3一侧上的腔体结构，也就是说，该腔体结构设置在非显示区域1103上靠近指纹识别模组3的一侧。
进一步的，本实施例中，容纳空间1101可以为内凹形结构，且内凹形结构的开口朝向指纹识别模组3，光源2通过开口放置在该内凹形结构内。
需要说明的是，本实施例中，为了便于更好的调整光源2的水平位置，内凹形结构的水平横向长度须大于光源2的横向长度，其中，横向为与显示模组1的表面平行的方向。本实施例中，通过调整光源2在容纳空间1101内的水平位置，相较于现有的LCD屏下指纹识别模组3，能够在不改变指纹识别模组3的结构尺寸的前提下，可以进一步缩短光源2与指纹探测区域中手指的距离，进而提升指纹信号强度。
进一步的，本实施例中，容纳腔为盲孔结构，光源2设置在显示盖板11靠近指纹识别模组3的一侧开设的盲孔结构内，且使得光源2并位于所述指纹识别模组3之上，能够有效缩短所述光源2距离所述显示模组1的垂直距离。
实施例三
进一步的，在上述实施例一和实施例二的基础上，如图3所示，光源2为独立于显示模组1的非可见光源，即本实施例中的光源2为独立且区别于显示模组1和指纹识别模组3的指纹检测光源，光源2用于向位于显示 模组1的显示区域1102相应位置处的指纹识别区域1105发射照射光，照射光在照射到指纹识别区域1105的手指时形成反射光，并透过指纹识别模组3上方的显示模组1传输至指纹识别模组3，进而提升指纹识别强度。
进一步的，本实施例中，显示盖板11在非显示区域1103与指纹识别模组3相邻的一侧上以及容纳的内壁上均设有遮挡层1104，通过遮挡层1104的设置，更好的对显示盖板11上的显示区域1102和非显示区域1102进行区分其中，本实施例中，遮挡层1104采用对光源2发出的光波具有透过性的材料制备而成，且制备遮挡层1104采用的材料对光源2发出的光波具有较高的透过性。
进一步的，本实施例中，当光源2为近红外光源时，遮挡层1104可以采用透红外的黑色油墨，如红外透视油墨，或其他能够对光源2发出的光波具有高透过性材料。
进一步的，本实施例中，显示盖板11还设有显示区域1102，非显示区域1103位于显示区域1102的外围，指纹识别区域1105至少部分位于显示区域1102内，即指纹识别区域1105可以位于显示区域1102内，或者指纹识别区域1105也可以局部位于显示区域1102内。
需要说明的是，本实施例中，显示区域1102为显示盖板11上用于显示信息的区域，其中，本实施例中的信息包括文字、图像、动画或其中几种的组合呈现出来的用于显示的信息。本实施例中，在显示盖板11上的不用于显示信息的区域为非显示区域1103，非显示区域1103位于显示区域1102的外围，即显示区域1102的外侧为非显示区域1103，上述实施例中的光源2和指纹识别模组3均位于非显示区域1103内。

进一步的，在上述实施例，如图3所示，第二电路板5与液晶显示组件的走线区域电连接后再与外部电路电连接，可以使第二电路板5连接至外部电路的连接线更为规范，或者本实施例中，如图4所示，第二电路板5与指纹识别模组3的走线区域电连接后再与外部电路电连接，可以使第二电路板5连接至外部电路的连接线更为规范的同时还能够通过外部电路一同控制光源2和指纹识别模组3的工作状态。

在上述实施例的基础上，本实施例提供一种光学指纹显示模组，如图3和图4所示，光学指纹显示模组至少包括显示模组1、以及上述实施例中的指纹识别组件，显示模组1至少包括显示面板12、以及位于显示面板12上的显示盖板11；
指纹识别组件包括：位于显示面板12之下的指纹识别模组3、以及光源2，显示盖板11上设有用于容纳所述光源2的容纳空间1101，以使光源2 设在指纹识别模组3之上；光源2用于向显示模组1上的指纹识别区域1105发射照射光，照射光在照射到指纹识别区域1105的手指时形成反射光，并透过指纹识别模组3上方的显示模组1传输至指纹识别模组3，进而提升指纹识别强度。
如图3所示，本实施例中，指纹识别模组3位于显示面板12的下方，通过在显示盖板11上设有容纳光源2的容纳空间1101，使得光源2位于容纳空间1101内且光源2位于指纹识别模组3的上方，本实施例的光学指纹显示模组相较于现有的LCD屏下指纹识别模组3，将光源2从指纹识别模组3内释放出来，在一定程度上减小了现有的LCD屏下指纹识别模组3中指纹识别模组3集成光源后的宽度，使得光源2位置的改变不会对指纹模组的尺寸造成影响，而且可以灵活改变光源2的位置，通过在显示盖板11上开设用于容纳光源2的容纳空间1101，使得光源2位于指纹模组的上方，进一步相较于现有的LCD屏下指纹识别模组3，缩短了光源2距离显示模组1的垂直距离，而本实施例中的光源2的水平位置可以在一定范围内自由调节，因此，本实施例的光学指纹显示模组相较于的现有的LCD屏下指纹识别模组3具有更高的指纹信号强度。
实施例六
进一步的，在上述任一实施例的基础上，本实施例中，显示盖板11包括显示区域1102和非显示区域1103，非显示区域1103位于显示区域1102的外围，且指纹识别模组3和光源2均设在非显示区域1103内，通过将光源2从指纹识别模组3中释放出来，可以将光源2任意设置在非显示区域1103内，即可以灵活改变光源2在非显示区域1103内的设置位置，相应的可以在一定范围内自由设置指纹识别模组3和指纹探测区域，以缩短光源2与指纹探测区域的手指的距离，提升指纹识别强度。
进一步的，在本实施例中，由于限于指纹识别模组3本身的宽度，指纹识别模组3位于非显示区域1103的顶部或底部，光源2分布在指纹识别模组3的至少一侧，以确保光源2与指纹探测区域有较近的距离。
实施例七
图5是本发明实施例七提供的指纹识别组件及光源的放置位置示意图，图6是本发明实施例七提供的另一种指纹识别组件及光源的放置位置示意图。
在上述实施例六的基础上，如图5和图6所示，本实施例中，当光源2设于非显示区域1103的侧壁时，指纹识别模组3位于非显示区域1103内靠近所述光源2的一角。
其中，本实施例中，具体的，如图5和图6所示，当光源2设于非显示区域1103底部的左侧壁时，指纹识别模组3位于非显示区域1103内底部靠近光源2的一角，此时，指纹探测区域位于显示盖板11的显示区域1102底部靠近光源2的一角，即指纹探测区域位于显示盖板11的显示区域1102的左下角；其中，本实施例中，光源2也可以设置在非显示区域1103底部的右侧壁，此时，指纹识别模组3和指纹探测区域的设置参考上述光源2设于非显示区域1103底部的左侧壁时指纹识别模组3和指纹探测区域的设置方式。本实施例中，由于光源2从指纹识别模组3内释放出来在显示盖板11内单独设置，因此，本实施例光源2的设置方式可以解放初光源2与指纹识别模组3之间的相对位置，在允许的范围内，可以自由设置光源2的位置，以设置不同区域的指纹探测区域，与此同时，由于光源2为独立于指纹识别模组3的单独的设置方式，光源2无需放置在显示模组1的非显示区域1103的底部区域，因此，本实施例中，光源2的上述设置方式能够使得显示模组1的非显示区域1103的底部区域即安装有本实施例光学指纹显示模组的电子装置的底部黑边宽度变窄。
实施例八
图7是本发明实施例八提供的指纹识别组件及光源的放置位置示意图。
进一步的，在上述实施例七的基础上，如图7所示，光源2设于非显示区域1103的顶部或底部时，光源2分布在指纹识别模组3的一侧或两侧。
其中，本实施例中，如图7所示，光源2可以设置在距离指纹探测区域手指较近的位置，不受限于指纹模组的设置位置，指纹识别模组3可以位于显示区域1102的底部或底部，指纹探测区域与指纹识别模组3的设置进行改变，例如：指纹识别模组3位于非显示区域1103的底部的中心位置时， 指纹探测区域可以位于显示盖板11的显示区域1102的正下方，光源2可以分布在指纹识别模子的一侧或两侧，此时，光源2距离显示模组1的垂直距离比光源2与指纹模组集成在一起的距离有所缩短，且光源2的水平距离也可调节。
实施例九
进一步的，在上述实施例的基础上，显示面板12至少包括位于指纹识别模组3上的液晶显示面板12、以及位于液晶显示面板12和电路板之间的彩色滤光层1203。
其中，本实施例中，液晶显示面板12可以为薄膜晶体管(Thin Film Transistor，简称：TFT)面板，可以为其他液晶显示面板12，如OLED面板。本实施例中，指纹识别模组3位于液晶显示面板12的下方且与液晶显示面板12的下方贴合，从手机屏幕上方无法看到指纹识别模组3。
其中，本实施例中，彩色滤光层1203为彩色滤光片基板，彩色滤光片基板位于TFT面板的上方，通过TFT上的信号与电压改变来控制液晶分子的转动方向，从而达到控制每个像素点偏振光出射与否而达到显示目的。
进一步的，在本实施例中，显示面板12还包括粘结层1204，粘结层1204位于显示盖板11和彩色滤光层1203之间，粘结层1204的第一面与分别与电路板和显示盖板11粘结，粘结层1204的第二面与彩色滤光层1203粘结。
其中，本实施例中，粘结层1204可以为贴合胶，可以为正反两个均具有粘性的物质。需要说明的是，本实施例中电路板和显示盖板11与彩色滤光层1203相邻的一面与粘结层1204的第一面粘结，彩色滤光层1203与显示盖板11相邻的一面与粘结层1204的第二面粘结，通过粘结层1204将电路板和显示盖板11与彩色滤光层1203贴合粘结、固定。
其中，本实施例中，光学指纹显示模组还包括背光模组，其中，背光模组可以设于显示模组1的下方，或者背光模组可以设于显示模组1和指纹识别模组3的下方，在本实施例中，对于背光模组的结构以及背光模组的设置位置不作进一步限定和赘述。
