具体实施方式
下面结合附图，对本公开实施例提供的指纹识别模组、其制作方法及显示装置的具体实施方式进行详细地说明。
附图中各部件的形状和大小不反映相应部件的真实比例，目的只是示意说明本公开内容。
图1示出了用于说明指纹识别功能的原理的示意图。如图1所示，光敏感应单元2可以接收手指指纹反射回来的光线而产生光电流，由于谷和脊反射的光线强度不同，产生的光电流也会不同，从而实现识别指纹的谷和脊的功能。
图2示意性地示出了一种常规的指纹识别模组。如图2所示，指纹识别模组中的光敏感应单元2包括：用于感测指纹按压时带来光强变化的光敏二极管21，以及用于控制光敏二极管21将光强变化转换为电信号输出的控制晶体管22。控制晶体管22的漏极会与光敏二极管21的一端相连，源极与读取信号线相连，栅极与扫描信号线相连。在通过扫描信号线加载扫描驱动信号时，控制晶体管22处于导通状态，从而使得读取信号线与光敏二极管21电连接，读取信号线可以对光敏二极管21加载反向偏压或将光敏二极管21上的电信号导出。为了保持光敏二极管21在反偏状态，需要对光敏二极管21的另一端加载固定电位。因此，如图2所示，光敏二极管21的另一端会通过遮光部23连接至与控制晶体管22的栅极同层设置的固定电位信号线24，并且，为了将上层的遮光部23与底部的固定电位信号线24连接，需要设置贯穿两者之间膜层的连接孔25。从图2中可以看出，设置的连接孔25会占用较大的空间，从而影响到光敏二极管21的面积。另外，受光敏感应单元2设置的位置限制，显示面板中各发光像素R、B和G之间大约具有20-26μm左右的距离，因此，连接孔25占用过多空间会使得光敏二极管21的面积较小，导致光敏二极管21在检测指纹时产生的光电流较小，从而影响到指纹的检测精度。
根据本公开实施例提供的一种指纹识别模组，如图3所示，包括：衬底基板100，设置在衬底基板100上的呈阵列排布的多个光敏感应单元200，设置于光敏感应单元200之上的遮光层300。衬底基板100背离光敏感应单元200的表面为指纹接触面A，即手指按压的表面。
光敏感应单元200包括：用于感测指纹按压时带来光强变化的光敏二极管201，以及用于控制光敏二极管200将光强变化转换为电信号输出的控制晶体管202。
如图4所示，遮光层300包括设置于光敏二极管201上方的第一遮光部301，以及固定电位信号线302。第一遮光部301与下方的光敏二极管201一端电性相连，第一遮光部301还与固定电位信号线302 相连，第一遮光部301和固定电位信号线302同层设置。
对于本公开实施例提供的上述指纹识别模组，将固定电位信号线302设置在光敏二极管201的上方，并直接采用遮光层300形成固定电位信号线302，因此，可以避免设置占用空间的连接孔，使光敏二极管201的所占面积最大化，有利于增大光敏二极管201在检测指纹时产生的光电流，从而提高指纹的检测精度。
值得注意的是，对于本公开实施例提供的指纹识别模组，各第一遮光部301与固定电位信号线302可以以各种方式连接，图4中仅是示意出了将每列第一遮光部301与一条固定电位信号线302相连的情况，在其他实施例中，还可以包含其他连接情况，在此不作赘述。
在本公开的实施例中，如图3所示，控制晶体管202设置于光敏二极管201与衬底基板100之间，控制晶体管202的漏极2021与光敏二极管201的一端相连，而控制晶体管202的源极2022与读取信号线(图3中未示出)相连，因此，在控制晶体管202的栅极2023加载扫描驱动信号时，控制晶体管202处于导通状态，使读取信号线与光敏二极管201的一端电连接，对光敏二极管201加载反向偏压或将光敏二极管201上的电信号导出。
在一个实施例中，如图3所示，在本公开实施例提供的上述指纹识别模组的光敏感应单元200中，光敏二极管201在衬底基板100上的正投影与控制晶体管202在衬底基板100上的正投影互不重叠。这样，可以使得照射到光敏二极管201的光线不会被反射至控制晶体管202的有源层，从避免或降低对控制晶体管202的开关性能的影响。
在具体实施时，本公开实施例提供的上述指纹识别模组中的控制晶体管202可以采用顶栅型薄膜晶体管，即薄膜晶体管的栅极设置于有源层之上。替代性地，也可以采用底栅型薄膜晶体管，如图3所示，即薄膜晶体管的有源层2024设置于栅极2023之上。
当选用顶栅型薄膜晶体管时，为了保证外部光线不会照射到控制晶体管202的有源层而影响控制晶体管202的开关性能，可以在顶栅型薄膜晶体管的底部设置能够遮挡有源层的遮光部。
当选用底栅型薄膜晶体管时，为了保证从显示面板发出的显示用光不会照射到控制晶体管202的有源层2024，而影响控制晶体管202的开关性能，可以在底栅型薄膜晶体管的上方设置能够遮挡有源层的 遮光部。因此，如图3和图4所示，在遮光层300的图形中，还可以包括：设置于控制晶体管202上方的第二遮光部303，该第二遮光部303至少覆盖控制晶体管202的有源层2024，以保证从显示面板发出的显示用光不会影响控制晶体管202的开关性能。
进一步地，在本公开实施例提供的上述指纹识别模组中，如图3所示，还可以将在同一光敏感应单元200上方的第一遮光部301和第二遮光部303电性相连，使其形成一体结构，这样可以屏蔽或降低显示面板复杂的电信号干扰，为指纹检测提供一个稳定的电环境，以提高指纹检测的精度。
进一步地，为了使指纹识别模组具备触控检测功能，在本公开的另一实施例提供的指纹识别模组中，如图5所示，还可以包括：设置于光敏感应单元200与衬底基板100之间的多个触控检测单元400。该触控检测单元400相对于光敏感应单元200设置于更接近用户的一侧，即，更接近衬底基板100的指纹接触面A。该触控检测单元400可以以不同的方式被实施。例如，在一个实施中，触控检测单元400可以是具有如图6所示的触控检测电极401图案的单层结构。在其它实施例中，触控检测单元400也可以包括两层触控检测电极。本发明并不限制触控检测单元400的具体实施形式。
基于同一发明构思，本公开实施例还提供了一种指纹识别模组的制作方法，该方法可包括以下步骤：
在衬底基板上形成呈阵列排布的多个光敏感应单元；该光敏感应单元包括：用于感测指纹按压时带来光强变化的光敏二极管，以及用于控制光敏二极管将光强变化转换为电信号输出的控制晶体管；
在光敏感应单元之上形成遮光层的图形，遮光层的图形包括：设置于光敏二极管上方的第一遮光部以及固定电位信号线；第一遮光部与下方的光敏二极管一端电性相连，第一遮光部还与固定电位信号线相连，第一遮光部和固定电位信号线处于同一层。
在另一实施例中，所述方法还包括：在制作第一遮光部和固定电位信号线时，同层制作设置于控制晶体管上方的第二遮光部。
基于同一发明构思，本公开的另外的实施例提供了一种显示装置，如图7a和图7b所示，包括：显示面板001，以及设置于显示面板001出光面的本公开的上述实施例提供的指纹识别模组002。该指纹识别模 组002中的光敏感应单元设置于衬底基板100面向显示面板001的表面，即指纹接触面A背离显示面板001。
本公开实施例提供的上述显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本公开实施例提供的显示装置中的指纹识别模组002的具体结构可以参见前述描述，重复之处不再赘述。另外，值得注意的是，在显示装置中可以将包括的多个触控检测单元400如图7a所示，设置于指纹识别模组002中的衬底基板100与光敏感应单元200之间；替代性地，也可以如图7b所示，将触控检测单元400设置于显示面板001，即触控检测单元400制作在显示面板001中。并且，如前所述，触控检测单元400的具体结构不做限定，可以有多种实现方式。
进一步地，如图7a和7b所示，为了不影响显示面板001的开口率，在本公开实施例提供的上述显示装置中，可以将指纹识别模组002中的各光敏感应单元200和遮光层300的图案设置为使得它们在显示面板001上的正投影处于显示面板001中的各亚像素之间的间隙处，即各光敏感应单元200和遮光层300的图案的位置对应于显示面板的非发光区域。
在具体实施时，本公开实施例提供的上述显示装置中的显示面板001可以是液晶显示面板，也可以是电致发光显示面板，还可以是其他平板显示面板，在此不做限定。
在具体实施时，本公开实施例提供的上述显示装置中的指纹识别模组002中的衬底基板100可以为保护盖板，即将指纹识别模组002制作在保护盖板朝向显示面板001的内表面。替代性地，也可以单独设置保护盖板，即将指纹识别模组002直接设置于显示面板001与保护盖板之间，在此不做限定。
此外，当本公开实施例提供的上述显示装置中的显示面板001为电致发光显示面板时，指纹识别模组002中的衬底基板100还可以复用作为封装盖板，即将指纹识别模组002制作在封装盖板朝向显示面板001的内表面。
本公开实施例提供了上述指纹识别模组、其制作方法及显示装置。指纹识别模组中设置在光敏感应单元之上的遮光层包括设置于光敏感 应单元的光敏二极管上方的第一遮光部，以及固定电位信号线，第一遮光部与下方的光敏二极管一端电性相连，第一遮光部还与固定电位信号线相连。本公开实施例所提出的指纹识别模组可以避免设置占用空间的连接孔，使光敏二极管的所占面积最大化，有利于增大光敏二极管在检测指纹时产生的光电流，从而提高指纹的检测精度。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本公开的这些修改和变型属于所附权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
