随着以手持移动终端为主导的终端电子设备智能化的高速发展，人体生物信息识别在电子设备中的应用越来越深入和广泛，从以前的通过生物信息识别解锁以唤醒电子设备，逐步发展到各种软件程序的身份识别、身份认证等。随着生物信息识别在电子设备中的广泛应用，生物信息识别的准确性以及电子设备，特别是显示类的电子设备对于指纹信息的识别能力和识别速度都随之提高。
相关技术中，应用于手机、平板电脑一类的电子设备上的生物信息识别，例如指纹识别，识别的方式主要为光学指纹识别，通常通过显示面板的光源照射指纹并反射，通过光学检测器件接收、记录或分析携带有特定生物信息的指纹反射光达到对指纹进行记录或者对特定指纹进行识别的功能。近年来，随着手机、平板电脑一类的电子设备的小型化要求，对于设置于电子设备内部的指纹识别模组的薄型化、小型化的要求也越来越高，如此则要求，实现指纹识别的光学检测器件的体积也要不断缩小，而为了保证对于生物信息识别的准确性，在显示屏上对于生物信息的采集面积至少应当保证在一个较小的面积范围内，这就导致指纹识别模组的结构难以进一步缩小，从而极大的影响了电子设备的小型化。

具体实施方式
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。
在本申请的描述中，需要说明的是，术语“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，或者是该申请产品使用时惯常摆放的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
还需要说明的是，除非另有明确的规定和限定，术语“设置”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
生物识别技术已广泛地应用到各种终端设备或电子装置上。生物特征识别技术包括但不限于指纹识别、掌纹识别、静脉识别、虹膜识别、人脸识别、活体识别、防伪识别等技术。其中，指纹识别通常包括光学指纹识别、电容式指纹识别和超声波指纹识别。随着全面屏技术的兴起，可以将指纹识别模组设置在显示屏下方的局部区域或者全部区域，从而形成屏下(Under-display)光学指纹识别；或者，也可以将光学指纹识别模组的部分或者全部集成至电子设备的显示屏内部，从而形成屏内(In-display)光学指纹识别。所述显示屏可以是有机发光二极管(Organic Light Emitting Diode，OLED)显示屏或液晶显示屏(LiquidCrystal Display，LCD)等。指纹识别方法通常包括指纹图像的获取、预处理、特征提取、特征匹配等步骤。上述步骤中的部分或者全部可以通过传统计算机视觉(Computer Vision，CV)算法实现，也可以通过基于人工智能(Artificial Intelligence，AI)的深度学习算法实现。指纹识别技术可以应用在智能手机、平板电脑、游戏设备等便携式或移动终端，以及智能门锁、汽车、银行自动柜员机等其他电子设备，以用于指纹解锁、指纹支付、指纹考勤、身份认证等。
应用于显示屏下的生物信息识别模组，通常需要通过接收、记录或分析携带有特定生物信息的反射光来实现对特定生物信息所属的个体的确认和识别，对于设置于生物信息识别模组上的显示屏来说，其自身首先需要实现所需的显示功能，因此，能够划分出来用于进行屏下生物信息识别的采集面积非常有限，而对于生物信息的提取，又要求需要有足够的携带生物信息的光束作为基础才能够得出准确的识别信息，在此基础上，模组能够获得的携带有生物信息的光束越多，其识别准确性、抗干扰能力、对于造假的识别能力等才能 够相应的得到提高。因此，如何在此有限的生物信息采集面积内充分的获取携带有特定生物信息的反射光束，并对这些反射光束进行处理，以从反射光束中获得尽可能多的特定的生物信息，从而有效的提高对于生物特征信息所属人进行确认和识别的准确性，是生物信息识别模组在具体应用中亟待解决和提高的重要问题。
当然，生物信息识别模组也未必需要必须集成于显示装置的显示屏下，在其他可行的应用场景中，生物信息模组可以作为单独的用于生物信息识别的模组存在。例如，可以在生物信息模组上设置透明的保护玻璃板或保护膜层，从而使得携带有生物信息的光束透过保护玻璃板入射至生物信息识别模组，进而被生物信息识别模组识别。
基于此，请参照图1和图2，本申请实施例提供了一种生物信息识别模组，该生物识别模组可以为指纹识别模组，该生物识别模组可以包括光路引导层10以及光学传感器20；光路引导层10可以包括多个光通道11，光学传感器20可以包括多个感光像素单元211，相邻的至少两个感光像素单元211组成感光像素单元组21；生物信息识别模组还可以包括设置在至少两个感光像素单元组21之间的间隙区30，间隙区30上方的携带生物信息的光束可以经光通道11被至少一个感光像素单元211接收。
需要说明的是，本实施例的生物信息识别模组可以应用于常见的终端设备，例如手机、平板电脑等手持显示设备，或者电视机、台式电脑、空调、冰箱等家用液晶显示类电器。另外，该生物信息识别模组用于对携带生物信息的光束进行识别，示例地，该携带生物信息的光束可以是来自人体手掌的掌纹、掌静脉、关节纹路、虹膜、人脸等。作为示例而非限制，生物信息可以为来自人体手指的指纹。为了便于理解，下文将主要以现实生活中较为常见的手持显示设备上的指纹识别为例进行示例说明。
图2为本申请实施例提供的生物信息识别模组的结构示意图之一，如图2所示，生物信息识别模组可以包括沿图2中所示方位上、下设置的光路引导层10和光学传感器20。其中，光路引导层10可以位于光学传感器20的上方，且光路引导层10可以包括多个光通道11，该多个光通道11可以配置成用于供携带生物信息的光束通过，从而入射至光学传感器20。需要说明的是，在本实施例中，上述多个光通道11可以呈矩阵形式排布于光路引导层10上，也可以呈环形排布于光路引导层10上，本申请不做具体限制。还有，光通道11的截面形状可以是呈倾斜的方形(平行四边形)，也可以是呈倾斜的上大、下小的梯形等，只要能使得携带生物信息的光束尽可能多的通过该光通道11顺利被光学传感器20接收即可。例如，当光通道11的截面形状为倾斜的梯形时，为了减小光束在光通道11内的光损失，还可以在光通道11内对应设置反射膜等，具体地，当光通道11的截面形状为倾斜的梯形时，该光通道11内对应设置的光学元件本领域技术人员可以根据实际情况进行具体设置和排布。
如图3所示，上述光学传感器20可以包括多个感光像素单元211，相邻的感光像素单元211可以组成感光像素单元组21。其中，光学传感器20的每个感光像素单元211都能够接收入射的携带有生物信息的光束。其中，组成感光像素单元组21的感光像素单元211的数量和位置在本申请实施例中未进行具体的限定。同一个感光像素单元组21中的多个感光像素单元211应当相互邻接，例如，至少相互邻接的两个感光像素单元211可以组成一个感光像素单元组21，又例如，依次相邻的三个感光像素单元211可以组成一个呈矩形的感光像素单元组21，又例如，还可以是，组成感光像素单元组21的多个感光像素单元211 以N*M的形式组合，其中，N为大于等于1的整数，M为大于等于2的整数。示例地，组成感光像素单元组21的多个感光像素单元211以2*2、2*3、3*3、4*4、4*3或者5*5等形式呈现，本申请不再一一列举。在本实施例中，N和M可以相等也可以不相等(当N和M相等时，则为组成感光像素单元组21的多个感光像素单元211以N*N的形式组合)。但须注意的是，当组成感光像素单元组21的多个感光像素单元211以N*M的形式组合时，由于M为大于等于2的整数，所以本申请组成感光像素单元组21的多个感光像素单元不包含1*1的形式。即，只要不是由1个感光像素单元211作为一个感光像素单元组21的形式，均属于本申请实施例提供的感光像素单元组21的可组合形式，在此不做穷举。
如图3所示，图3示出的是组成感光像素单元组21的多个感光像素单元211以3*3的形式呈现，且感光像素单元组21包括4组时的结构示意图。在这里，需要说明的是，当组成感光像素单元组21的多个感光像素单元211以3*3的形式呈现时，光学传感器20不限于包括4组感光像素单元组21，可以是大于4组，图3仅为本申请给出的一种示例；如图4所示，图4示出的是组成感光像素单元组21的多个感光像素单元211以2*2的形式呈现，且感光像素单元组21包括4组时的结构示意图。同样地，当组成感光像素单元组21的多个感光像素单元211以2*2的形式呈现时，光学传感器20不限于包括4组感光像素单元组21，其可以是大于4组。如图5所示，图5示出的是组成感光像素单元组21的多个感光像素单元211以2*4的形式呈现，且感光像素单元组21包括2组时的结构示意图。同样地，当组成感光像素单元组21的多个感光像素单元211以2*4的形式呈现时，光学传感器20不限于包括2组感光像素单元组21，其可以是大于2组。
需要说明的是，光学传感器20的感光接收面可以为平面，也可以根据实际需要设计为突出的弧面、凹陷的弧面、斜面等，在本实施例中，采用通常常见的形式，即光学传感器20的感光接收面设计为平面，那么，组成光学传感器20的感光接收面的每个感光像素单元组21的接收面也为平面，组成一个感光像素单元组21的多个感光像素单元211的接收侧共同形成一个感光像素单元组21的平面的接收面，多个感光像素单元组21的感光接收面共同作为光学传感器20的感光区域。
请参照图3至图5所示，本实施例提供的生物信息识别模组还可以包括设置在至少两个感光像素单元组21之间的间隙区30。示例地，上述间隙区30可以在相邻的两个感光像素单元组21之间均设置(如图1和图3)；或者，也可以在部分相邻的感光像素单元组21之间。例如，可以仅设置于上下分布的感光像素单元组21之间(如图4和图5)。又例如，可以仅设置于左右分布的感光像素单元组21之间(图未示)。再例如，可以设置于部分上下分布的感光像素单元组21之间，和/或，部分左右分布的感光像素单元组21之间(图未示)。其中，本申请将间隙区30设置于至少两个感光像素单元组21之间，且使得间隙区30上方的光束被至少一个感光像素单元211接收，可以扩大生物信息采集面积。示例地，在一种可行的实施例中，该间隙区30可以用于电路信号线的排布，以收集电信号。在另一种可行的实施例中，该间隙区30可以用于电路元件在其上进行排布。在至少两个感光像素单元组21之间设置间隙区30并在间隙区排布电路信号线后，就能够在光学传感器20上不再设置走线区域，从而节省光学传感器20的结构尺寸。
由于本实施例提供的间隙区30是设置在至少两个感光像素单元组21之间的，因此，在一定程度上，本申请的电路信号线和/或电路元件可以尽可能减少对光学传感器20的整 体面积的占用，从而节省出更多的面积用于排布感光像素单元211，进而可以实现在不增加显示屏40的生物信息采集面积的情况下，有效减小了光学传感器20的感光区域面积，降低模组的成本，使得生物信息识别模组的结构尺寸利用率尽可能的最大化，进而为采用本申请实施例的生物信息识别模组的电子设备节省出更多的内部空间。
其中，本申请实施例中对于间隙区30的设置数量和设置位置不做具体限定，例如，可以为在任意两个感光像素单元组21之间均设置间隙区30，从而在整个光学传感器20上形成由间隙区30组成的横纵交叉的网格状，可以为以相同或平行的方向连续形成的多个间隙区30，也可以为其他的规律或不规律的方式形成的多个间隙区30的各种组合形状。
在本申请的一种可实现的实施例中，上述间隙区30的宽度可以在10μm至30μm之间，示例地，间隙区30的宽度可以为10μm、15μm、20μm、25μm或者30μm等，本申请不再一一列举。具体地，对于间隙区30的数量、位置、形状以及尺寸等，本领域技术人员可以根据所需设置的电路信号线和/或电路元件的情况进行具体设置。
另外，在图4中，感光像素单元组21呈矩阵形式排布，对应地，上述间隙区30的形状呈长方形。应理解，该长方形的间隙区30仅为对应矩阵形式排布的感光像素单元211时所呈现的一种情况，并非是对本申请的间隙区30的形状的唯一限制或者是本申请实施例唯一可以支持的方案。间隙区30的形状应当与多个感光像素单元组21的排布形式有关，具体形状根据实际情况而定，本申请不做限定。
示例地，间隙区30可以在光学传感器20上形成至少一个带状区域或者至少一个横纵交叉连接的区域。如图3所示，图3为光学传感器20的结构示意图之一，在该情况下，间隙区30为形成在光学传感器20上一个横纵交叉连接的区域；如图4所示，图4为光学传感器20的结构示意图之二，在该情况下，间隙区30为形成在光学传感器20上一个带状区域。当然，在其他的实施例中，上述间隙区30还可以是形成在光学传感器20上多个横纵交叉连接的区域或者是形成在光学传感器20上多个带状区域，在前述说明中，已经对间隙区30的形成形式进行了举例说明，此处不再枚举。
此外，在本申请实施例的一种可选的实施方式中，上述间隙区30可以包括用于排设电路信号线的第一预留区；和/或，上述间隙区30还可以包括用于设置电路元件的第二预留区。示例地，当间隙区30为形成在光学传感器20上的一个横纵交叉连接的区域时，第一预留区和第二预留区可以分别为横向设置的区域和纵向设置的区域；当间隙区30为形成在光学传感器20上的多个横纵交叉连接的区域时，第一预留区可以设置于一个横纵交叉的区域上，第二预留区可以设置于另一个横纵交叉的区域上；当间隙区30为形成在光学传感器20上一个带状区域时，第一预留区和第二预留区可以分别为该带状区域的不同位置；当间隙区30为形成在光学传感器20上多个带状区域时，第一预留区可以设置于一个带状区域上，第二预留区可以设置于另一个带状区域上。
在本申请实施例中，间隙区30上方的携带生物信息的光束可以经过光通道11被至少一个感光像素单元211接收，这样，本申请设置的间隙区30也不会对位于其上方的携带生物信息的光束的正常接收造成影响(位于间隙区30上方的携带生物信息的光束可以被至少一个感光像素单元211接收)，如此一来，本申请提供的生物信息识别模组将可以在不增加显示屏40的生物信息采集面积的情况下，有效减小光学传感器20的感光区域面积，从而减小光学传感器20的体积，降低生物信息识别模组的成本。
请参照图6所示，图6为图3所示的A-A处的断面图，通过图3和图6可以看出，位于间隙区30上方的携带生物信息的光束可以通过光通道11被至少一个感光像素单元211接收。需要说明的是，图3和图6所示的仅为本申请实施例的一种情况，通过使光通道11倾斜，位于横向设置的间隙区30上方的携带生物信息的光束被感光像素单元组21中的一个特定的感光像素单元211(对应至图3中，即为3*3形式的感光像素单元组21的感光像素单元211g)接收的情况。在其他的实施例中，位于横向设置的间隙区30上方的携带生物信息的光束还可以是被感光像素单元组21中靠近中心的一个或多个感光像素单元211所接收等。
综上，本申请实施例提供的生物信息识别模组，包括光路引导层10以及光学传感器20；光路引导层10包括多个光通道11，光学传感器20包括多个感光像素单元211，相邻的至少两个感光像素单元组21成感光像素单元组21；生物信息识别模组还包括设置在至少两个感光像素单元组21之间的间隙区30，间隙区30上方的携带生物信息的光束经光通道11被至少一个感光像素单元211接收。这样，在使用时，携带生物信息的光束可以通过多个光通道11传输至光学传感器20，从而被光学传感器20的感光像素单元211接收并识别；同时，位于间隙区30上方的携带生物信息的光束可以经光通道11被至少一个感光像素单元211接收，其正常传输也不会受到影响。本申请通过将间隙区30设置于至少两个感光像素单元组21之间，且使得间隙区30上方的携带生物信息的光束经光通道11被至少一个感光像素单元211接收，如此，一方面，本申请能够使得更大区域范围内的携带生物信息的光束入射光学传感器20，即在感光像素单元211的总面积(即感光区域的面积)不变的情况下，增大了显示屏40的生物信息采集面积，从而使得生物信息识别模组能够接收到更多的携带生物信息的光束的光信号，进而获得更多的生物信息，从而有利于生物信息识别的精准性；另一方面，在不必增加显示屏40的生物信息采集面积的情况下，本申请可以提高光学传感器20的感光像素单元211的总面积(即感光区域的面积)的有效利用率，减小光学传感器20的感光区域面积，从而缩小光学传感器20的体积，进而为采用本申请提供的生物信息识别模组的电子设备节省出更多的内部空间，同时可以降低生物信息识别模组的成本。
请参照图2所示，在本申请实施例的一种可实现的实施方式中，光路引导层10的光通道11可以包括倾斜光通道111，倾斜光通道111与垂直于光学传感器20表面的直线之间可以具有夹角θ。如此，在光学传感器20的感光区域面积不变的情况下，由于光通道11中包括倾斜光通道111，这样，位于显示屏40外侧的携带生物信息的光束(即与光学传感器20正对的显示屏40的区域之外的区域)也能够通过倾斜光通道111的导向作用入射至光学传感器20的感光区域，从而使得携带生物信息的光束的入光范围增大，进而使得光学传感器20能够尽可能地接收到上方更大面积范围内的携带有生物信息的光束。由图2中示出的方向能够直观看到，本实施例提供的生物信息识别模组的感光像素单元组21可以接收到位于间隙区上方的携带生物信息的光束。很显然，本申请由于将光通道11设置为倾斜光通道111，可以使得光学传感器20接收到比其自身的感光区域的面积更大生物信息的采集面积。
示例地，上述倾斜光通道111与垂直于光学传感器20表面的直线之间的夹角θ可以在0°至45°之间。示例地，倾斜光通道111与垂直于光学传感器20表面的直线之间的夹角θ可以为0°、2°、5°、10°、15°、30°、40°或者45°等。
需要说明的是，光路引导层10的光通道11包括倾斜光通道111的同时，同样可以还包括不呈倾斜状态的光通道11，例如，可以使得位于光路引导层10最中心的倾斜光通道111与垂直于光学传感器20表面的直线之间的夹角θ为0°(即可以认为此处的光通道11是不呈倾斜状态、不具有该夹角θ的光通道11)。示例地，在一种实施例中，与感光像素单元组21对应的多个光通道11中，自中心的光通道11向远离中心的光通道11的直线方向排布的倾斜光通道111的夹角θ的角度可以呈递增的形式设置。
在这里，需要说明的是，本申请对光通道11的形成方式不做限定。例如，光通道11可以由准直孔组成；又例如，光通道11也可以由至少两层光阑孔组成；再例如，光通道11还可以由微透镜和至少两层光阑孔组成。请参照图1和图13至图15，图中示出的是光通道11的上部截面和下部截面映射到光学传感器20上的结构示意图，需要说明的是，在图1和图13至图15中大圆表示光通道11上部的横截面，例如可以是最上层的光阑孔；图中小圆表示光通道11下部的横截面，例如，可以是最下层的光阑孔；图14和图15中的示出的带箭头的虚线表示光束的传输方向(即光束朝向感光像素单元组21的中心传输)。
优选地，可以将最下层光阑孔的中心与像素单元的中心对位，而不以图中画出的示例为限制。应理解，本申请实施例中光通道11仅是以上大下小(即上部横截面孔径大，下部横截面孔径小)的形式进行举例说明，不应当看做是对本申请的光通道11的形状的唯一限制。示例地，在其他可行的实施例中，光通道11的孔径还可以是上下一致的。
在本申请实施例的一种可行的实施方式中，感光像素单元211可以包括：第一感光像素单元211A，第一感光像素单元211A通过倾斜光通道111接收与第一感光像素单元211A相邻的间隙区30上方的光束。
请参照图3和图6所示，以组成感光像素单元组21的多个感光像素单元211以3*3的形式组合为例进行说明，第一感光像素单元211A为该感光像素单元组21中的感光像素单元211g，则该第一感光像素单元211A可以接收水平方向的间隙区30上方的光束。需要说明的是，当第一感光像素单元211A为该感光像素单元组21中的感光像素单元211i时，则该第一感光像素单元211A可以接收如图3所示的水平方向的间隙区30上方的光束，也可以接收竖直方向的间隙区30上方的光束。
当生物信息识别模组只包括带状区域时，第一感光像素单元211A可以通过倾斜光通道111接收与第一感光像素单元211A相邻的间隙区30上方的光束。以组成感光像素单元组21的多个感光像素单元211为如图5所示的2*4的形式组合为例进行说明，假设第一感光像素单元211A为感光像素单元组21的感光像素单元211j为例，该第一感光像素单元211A可以接收其上方的间隙区30(即图5中的第二间隙区32)上方的光束；假设第一感光像素单元211A为感光像素单元组21的感光像素单元211n为例，该第一感光像素单元211A可以接收其下方的间隙区30(即图5中的第一间隙区31)上方的光束。
当生物信息识别模组至少包括横纵交叉连接的区域时，第一感光像素单元211A可以通过倾斜光通道111接收与第一感光像素单元211A相邻的其中一个或者多个间隙区30上方的光束。以组成感光像素单元组21的多个感光像素单元211以如图3所示的3*3的形式组合为例进行说明，假设第一感光像素单元211A为感光像素单元组21的感光像素单元211v为例，该第一感光像素单元211A可以接收其上方的间隙区30和/或右边的间隙区30上方的光束。
另外，请参照图9，在本申请实施例的一种实施方式中，第一感光像素单元211A对应的倾斜光通道111可以沿着光束的方向朝向感光像素单元组21的中心倾斜。这样，所有携带生物信息的光束能够都朝向感光像素单元组21的中心倾斜入射，从而使得入射至光学传感器20的感光区域的光束尽可能的增多，而光学传感器20由于通过间隙区30进行线路的走线等排布，不需要再专门划分走线区域，所以光学传感器20的面积还能够相应的减少，从而缩小整个模组的体积。
其中，第一感光像素单元211A对应的倾斜光通道111沿着光束的方向朝向感光像素单元组21的中心倾斜，可以包括多种情况。例如，当间隙区30只包括带状区域时，上述中心可以为感光像素单元组21的中心轴线。示例地，如图14所示，在这里，需要说明的是，图14中示出的带箭头的虚线表示光束的传输方向，即光束朝向感光像素单元组21的中心传输。图14中的直径较大的圆孔是光通道11远离光学传感器20的一端的横截面，直径较小的圆孔是光通道11靠近光学传感器20的一端的横截面。此时第一感光像素单元211A(假设为每个感光像素单元组21第一排左边第一个感光像素单元211)对应的倾斜光通道111沿光束的方向朝向感光像素单元组21的水平的中心轴线倾斜。示例地，当每个感光像素单元组21第一排左边第一个感光像素单元211作为该感光像素单元组21的第一感光像素单元211A时，第一感光像素单元211A上方的间隙区(即第二间隙区32)的光束由第一感光像素单元211A接收。示例地，当每个感光像素单元组21第二排左边第一个感光像素单元211作为该感光像素单元组21的第一感光像素单元211A时，第一感光像素单元211A下方的部分间隙区(即第一间隙区31)的光束由第一感光像素单元211A接收。
又例如，当间隙区30包括至少一个横纵交叉连接的区域时，示例地，如图15所示，此时第一感光像素单元211A对应的倾斜光通道111可以沿光束的方向朝向感光像素单元组21的水平的中心轴线倾斜(假设第一感光像素单元211A为每个感光像素单元组21第一排左边第一个感光像素单元211)；第一感光像素单元211A对应的倾斜光通道111还可以沿光束的方向朝向感光像素单元组21的几何中心倾斜(假设第一感光像素单元211A为每个感光像素单元组21第一排右边第一个感光像素单元211)；第一感光像素单元211A对应的倾斜光通道111又可以沿光束的方向朝向感光像素单元组21的竖直的中心轴线倾斜(假设第一感光像素单元211A为每个感光像素单元组21第二排右边第一个感光像素单元211)。
在另一种可行的实施例中，可选地，感光像素单元211可以包括：第一感光像素单元211A，第一感光像素单元211A通过倾斜光通道111接收与除第一感光像素单元211A以外的其它感光像素单元211相邻的间隙区30上方的光束。
换言之，第一感光像素单元211A可以通过倾斜光通道111接收除自身以外的其他感光像素单元211B相邻的间隙区30上方的光束。请参照图3和图11，当第一感光像素单元211A为该3*3形式组合的感光像素单元组21中的一个感光像素单元211时，假设第一感光像素单元211A为感光像素单元211i，则该第一感光像素单元211A可以接收与感光像素单元211h相邻的间隙区30上方的光束。应理解，第一感光像素单元211A接收与感光像素单元211h相邻的间隙区30上方的光束仅为本申请的一种示例，并非是对当感光像素单元211i作为第一感光像素单元211A时，其所接收的其它感光像素单元211相邻的间隙区30上方的光束的特定限制。例如，在其他的实施例中，当第一感光像素单元211A为感光像素单元211i时，该第一感光像素单元211A还可以是接收与感光像素单元211f相邻的间隙区30上 方的光束或者感光像素单元211g相邻的间隙区30上方的光束等等，本申请不再一一列举。
其中，在本申请的一些实施例中，上述除第一感光像素单元211A以外的其它感光像素单元211可以包括：在同一感光像素单元组21中、位于第一感光像素单元211A对侧的感光像素单元211。在这里，需要说明的是，对侧的感光像素单元211包括与第一感光像素单元211A上、下镜面相对的感光像素单元211、与第一感光像素单元211A左、右镜面相对的感光像素单元211，以及第一感光像素单元211A对角的感光像素单元211。示例地，以第一感光像素单元211A为图3示出的3*3形式组合的感光像素单元组21中的一个感光像素单元211为例(为便于描述，假设该第一感光像素单元211A为感光像素单元211a)，这时，第一感光像素单元211A可以接收与感光像素单元211a上、下镜面相对的感光像素单元211g相邻的间隙区30上方的光束；或者，第一感光像素单元211A可以接收与感光像素单元211a左、右镜面相对的感光像素单元211c相邻的间隙区30上方的光束；再或者，第一感光像素单元211A可以接收与感光像素单元211a对角的感光像素单元211i相邻的间隙区30上方的光束。
可以包括第一感光像素单元211A上方的感光像素单元211(感光像素单元211b)、第一感光像素单元211A下方的感光像素单元211(感光像素单元211h)、第一感光像素单元211A左边的感光像素单元211(感光像素单元211d)、第一感光像素单元211A右边的感光像素单元211(感光像素单元211f)、第一感光像素单元211A对角的感光像素单元211(感光像素单元211g、第一感光像素单元211c、第一感光像素单元211a、第一感光像素单元211i)。
在本申请实施例的一种实施方式中，在感光像素单元组21内的、相对于该感光像素单元组21的中心对称的两个感光像素单元211对应的倾斜光通道111可以在中心的上方相交，使得第一感光像素单元211A通过倾斜光通道111接收在同一感光像素单元组21中、与第一感光像素单元211A中心对称的感光像素单元211相邻的间隙区30上方的光束。
示例地，当两个倾斜光通道111在感光像素单元组21的中心的上方相交时，为便于理解，请参照图3和图7所示，在一种可实现的方式中，本实施例以组成感光像素单元组21的多个感光像素单元211以3*3的形式组合，以相对于该感光像素单元组21的中心对称的两个感光像素单元211分别为感光像素单元211d和感光像素单元211f为例，在对该两个感光像素单元211的连线所在平面断面可以得到如图7所述的结构示意图，此时，两个感光像素单元211分别对应的倾斜光通道111在感光像素单元组21的中心的上方相交。当组成感光像素单元组21的多个感光像素单元211以3*3的形式组合时，感光像素单元211d相邻的间隙区30上方的光束可以通过对应的倾斜光通道111被感光像素单元211f接收，感光像素单元211f相邻的间隙区30上方的光束可以通过对应的倾斜光通道111被感光像素单元211d接收。
示例地，在另一种可实现的方式中，还可以为使得两个倾斜光通道111在光路引导层10内形成交叠区域，为便于理解，请参照图3和图8所示，仍旧以相对于该感光像素单元组21的中心对称的两个感光像素单元211分别为感光像素单元211d和感光像素单元211f为例，对该两个感光像素单元211的连线所在的平面断面可以得到如图8所述的结构示意图，此时，两个感光像素单元211分别对应的倾斜光通道111在感光像素单元组21的中心的上方且在光路引导层10内呈相交设置。需要说明的是，图8中示出的光路引导层10为 一个较厚的层级，光通道11包括在其中完整的形成，若光路引导层10包括多个遮光层，倾斜光通道111的相交点也可以位于两个遮光层之间。
在本实施例中，在感光像素单元组21内的、相对于该感光像素单元组21的中心对称的两个感光像素单元211对应的倾斜光通道111在中心的上方也可以不相交。示例地，为便于对比理解，请结合如图3和图9所示，相对于该感光像素单元组21的中心对称的两个感光像素单元211分别通过各自对应的倾斜光通道111接收与自身相邻的间隙区30上方的光束，而非接收与对方相邻的间隙区30上方的光束。当然，这种情况仅为本申请提供的在感光像素单元组21内的、相对于该感光像素单元组21的中心对称的两个感光像素单元211对应的倾斜光通道111在中心的上方不相交的一种形式，不应当看作是本申请的限制。
在本申请实施例的一种实施方式中，与一个感光像素单元组21对应的多个倾斜光通道111中，相对于该感光像素单元组21的中心对称的两个倾斜光通道111的夹角相同。例如，如图3和图7所示，当组成感光像素单元组21的多个感光像素单元211以3*3的形式组合时，感光像素单元211d对应的倾斜光通道111与感光像素单元211f对应的倾斜光通道111分别与垂直于光学传感器20表面的直线之间的夹角相等。
示例地，在另一种实施例中，与一个感光像素单元组21对应的多个倾斜光通道111中，与该感光像素单元组21的中心等距的感光像素单元211所对应的倾斜光通道111的夹角可以相同。
以图3所示的组成感光像素单元组21的多个感光像素单元211以3*3的形式组合为例进行说明，则对应地，除感光像素单元211e对应的倾斜光通道111之外，其余的感光像素单元211对应的倾斜光通道111分别与该感光像素单元组21的中心线之间的夹角θ的角度是相等的。当感光像素单元组21呈其他形式组合时，本领域技术人员可以同理推导得到，故本申请不再赘述。
示例地，在再一种实施例中，与一个感光像素单元组21对应的多个倾斜光通道111中，与该感光像素单元组21的中心距离近的倾斜光通道111的夹角角度可以小于等于与该感光像素单元组21的中心距离远的倾斜光通道111的夹角θ的角度。
请参考图2所示，即越靠近该感光像素单元组21中心的感光像素单元211，其对应的倾斜光通道111与感光像素单元组21的中心线之间的夹角θ越小；反之，夹角θ越大。以图10所示的组成感光像素单元组21的多个感光像素单元211以4*4的形式组合为例进行说明，感光像素单元组21的感光像素单元211r、感光像素单元211s、感光像素单元211t、感光像素单元211u分别对应的倾斜光通道111与感光像素单元组21的中心线之间的夹角θ的角度小于该感光像素单元组21的其他感光像素单元211B对应的倾斜光通道111与感光像素单元组21的中心线之间的夹角θ的角度。在这里，需要说明的是，每个感光像素单元组21的倾斜光通道111的倾斜角度可以是一致的。换言之，每个感光像素单元组21可以完全相同(请参照图2所示)。
请再结合参照图12和图13，在本申请的一种可选的实施例中，光路引导层10可以包括间隔设置的至少两层遮光层，在遮光层上可以形成有光阑孔，至少两层的遮光层上对应的至少两个光阑孔形成光通道11的至少一部分。
为便于描述和理解，上述至少两层遮光层可以分述为第一遮光层12A和第二遮光层12B；遮光层上的光阑孔可以分为位于第一遮光层12A上的第一光阑孔121和位于第二遮光层 12B上的第二光阑孔122。其中，当遮光层包括超过两层时，则同理继续划分。以下本实施例中将以遮光层包括两层为例进行示例说明。携带生物信息的光束能够依次通过第一遮光层12A的第一光阑孔121和第二遮光层12B的第二光阑孔122入射至光学传感器20，从而被光学传感器20上的感光像素单元211所接收。
应理解，遮光层的设置是为了便于引导携带生物信息的光束自遮光层的光阑孔入射至光学传感器20的感光区域上，具体地，光阑孔的设置可根据光通道11的倾斜程度设置，本申请不做限制。示例地，上述遮光层可以包括两层、三层或者四层等，具体层数本领域技术人员可以根据实际情况而定。
请再结合参照图13，图13示出的是遮光层包括两层时，第一光阑孔121和第二光阑孔122投影在光学传感器20上的结构示意图。在这里，需要说明的是，图13所示出的第一光阑孔121为设置于第一遮光层12A上的用于引导光束通过的孔；第二光阑孔122是设置于第二遮光层12B上的用于引导光束通过的孔。在本实施例中，第一光阑孔121的孔径大于第二光阑孔122的孔径，且第二光阑孔122相对第一光阑孔121而言更靠近感光像素单元组21的中心区域。这样，便可以实现光束依次自第一光阑孔121和第二光阑孔122后光束是呈朝向感光像素单元211的中心收敛的。除此之外，本申请对第一光阑孔121和第二光阑孔122的截面形状也不做限制。示例地，第一光阑孔121和第二光阑孔122的截面直径可以为圆形、方形或者不规则图形中的一种或者多种等。
请再结合参照图16，在本申请实施例的一种实施方式中，光路引导层10还可以包括在遮光层上设置的微透镜组13，微透镜组13可以包括多个微透镜单元131，微透镜单元131可以形成光通道11的至少一部分。这样一来，微透镜单元131和光阑孔便可以共同形成光通道11。
其中，微透镜单元131能够对携带生物信息的光束起到一定程度的汇聚和导向作用。即微透镜单元131能够汇聚尽可能多的携带生物信息的光束以导向至光学传感器20的感光区域中。通过微透镜单元131汇聚后的携带生物信息的光束能够依次经过至少两层遮光层的光阑孔后入射至光学传感器20，从而被光学传感器20的感光像素单元211所接收。
在本申请实施例的一种实施方式中，携带生物信息的光束可以通过一个微透镜单元131被一个感光像素单元组21接收。即，一个微透镜单元131对应一个感光像素单元组21。
请再结合参照图17，本申请实施例的另一方面，提供一种电子设备，该电子设备可以包括显示屏40，以及设置在显示屏40下方的如前述任意一项的生物信息识别模组。
这样，用户可以将手指、手掌等具备个体生物特征的载体贴合放置于显示屏40的生物信息识别区41，以屏下指纹识别为例，照射在手指纹路上并反射的光束能够将照射的手指位置的纹路特征作为指纹信息进行携带，携带有指纹信息的光束经过生物信息识别模组中光路引导层10的引导传输后入射光学传感器20。本申请通过接收间隙区30上方的携带生物信息的光束，可以使得更大区域范围内的携带生物信息的光束入射到光学传感器20，使得电子设备接收到更多的来自指纹反射的光信号，从而获得更多的指纹信息，如此，在不增加显示屏40的生物信息识别区41的面积的情况下，能够有效增加光学传感器20的像素采集范围，提高生物信息识别的识别精度，同时能够降低电子设备的制造成本，减少模组的体积，为电子设备节省出更多的内部空间。
请再结合参照图18，在本申请实施例的一种实施方式中，在显示屏40上可以设置有生 物信息识别区41，生物信息识别区41可以为指纹识别区，生物信息识别区41可以包括与多个感光像素单元组21对应的多个分区411，来自分区411的携带生物特征信息的光束可以通过光通道11由对应的感光像素单元组21接收。其中，上述分区411的个数不做限定，例如可以包括2个分区411、3个分区411、4个分区411(如图18)或者5个分区411等。还有，本申请对分区411的形状不做限定，其可以是方形或者多边形等。可选地，分区411的形状可以与光学传感器20的感光像素单元组21的排布方式相对应。例如，若感光像素单元组21为方形，则分区411的形状可以为方形；若感光像素单元组21为多边形，则分区411的形状也为多边形。
为了获取到更多的携带生物信息的光束，在本申请实施例的一种实施方式中，至少一个分区411在光学传感器20上的正投影面积可以大于其对应的感光像素单元组21的面积。这样，用户带有个体生物特征的载体贴合放置于显示屏40的生物信息识别区41时，各个分区411可以获取尽可能多的生物信息，从而将携带该生物信息光束入射至光学传感器20的感光区域。
在本申请实施例的一种实施方式中，相邻的至少两个分区411可以在光学传感器20上的正投影具有重叠区412。即如图18所示，相邻的两个分区411具有重叠区412。这样，可以避免位于两个分区411之间的携带生物信息的光束无法被光学传感器20接收的情况发生，从而提高携带生物信息的光束的采集范围。
为避免重叠区412过大造成面积浪费，或者重叠区412域较小导致发生漏采集的情况，在本实施例中，上述重叠区412可以为矩形，重叠区的宽度W3可以在3-5微米之间。示例地，该重叠区的宽度W3可以为3μm、4μm或者5μm等。
以上所述仅为本申请的实施例而已，并不用于限制本申请的保护范围，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
