 本发明的最佳实施方式
下面将结合本揭示实施例中的附图，对本揭示实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本揭示一部分实施例，而不是全部的实施例。基于本揭示中的实施例，本领域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，都属于本揭示保护的范围。
传统的识别模组中，尤其在手机等电子显示设备中，需要在显示屏幕上的一区域内开设一个单独的孔来放置摄像头，从而实现人脸识别的功能，而这种工艺技术会影响产品的设计美观，同时还增加了生产工艺的复杂性，增加了生产的成本。
在本揭示的实施例中，如图1所示，图1为本揭示实施例的识别模组的膜层结构示意图。揭示实施例的识别模组包括基板100，设置在基板100之上的感光层101，设置在感光层101上的显示构件102以及设置在所述显示构件102上的保护层103。其中，在显示构件102内设置有可发射红外光的发射装置，当进行识别功能时，显示构件102发射红外光，红外光由被识别物体，如人脸反射回来后，被感光层101接收，感光层101接收到反射回来的红外光信号后并将其转换成光信号，进而产生电流，电流再传输到识别芯片中，经过识别芯片的进一步处理，实现人脸识别功能，所述显示构件包括显示层和红外灯，所述显示层可为液晶显示层。
具体的，本揭示实施例中，如图2所示，图2为本揭示实施例的感光层结构示意图。感光层还包括电子传输层200、光敏材料层201以及空穴传输层202。在设置各膜层时，光敏材料层201设置在电子传输层200上，空穴传输层202设置在光敏材料层201之上。感光层主要用来接收人脸反射回来的红外光，当光线照射到感光层的光敏材料层201上，该层材料会产生激子，即空穴-电子对，被激活的空穴和电子再分别传输到空穴传输层202以及电子传输层200内，进而形成电流。同时，识别模组中还设置有相应的芯片，电流流向该芯片内，并再次被芯片处理，完成了信号的传递及转换，实现了人脸识别功能。
其中，光敏材料层201的材料包括有机光敏材料，或为无机光敏材料，如非晶硅材料（a-Si）。
如图3所示，图3为本揭示另一实施例的识别模组结构示意图。识别模组包括：基板300、设置在基板300上的感光层301、设置在感光层301之上的液晶显示层302、设置在液晶显示层302之上的红外灯303，以及设置在红外灯303之上的保护层304。在本揭示实施例中，液晶显示层302与红外灯303一同构成了图1中的显示构件102。此时，红外灯303设置在所述液晶显示层302膜层之上，在设置红外灯303时，红外灯303在液晶显示层302的表面内为整面涂覆，这样，在进行人脸识别时，识别角度更大，识别的区域也更广。
在设置红外灯与液晶显示层时，如图4所示，图4为本揭示又一实施例中识别模组结构示意图。本揭示实施例中的识别模组包括至下而上依次设置的基板400、感光层401、显示构件402及保护层403。其中，显示构件402由红外灯与液晶显示层一同构成，即将红外灯与液晶显示层设置在同一层中。此时该显示构件402膜层的厚度不大于图3中将红外灯303设置在液晶显示层302上时显示构件的厚度。从而进一步的降低了模组的整体厚度，保护层403可为钢化玻璃。
当红外灯与液晶显示层设置在同一层时，如图5所示，图5为本揭示实施例中识别模组中显示层的俯视图。其中，所述俯视图中包括第一区域500、第一区域500内的像素模块501、第二区域503以及设置在第二区域503内的红外灯502。第一区域500与第二区域503相邻，同时，由于在本揭示实施例中，液晶显示层与红外灯设置在同一层中，因此，将红外灯502只设置在第二区域503内，而第一区域500内只设置像素模块501。这样，设置的红外灯502不会影响到显示模组的整个显示效果，同时还减小了显示层的膜厚并降低了识别模组的制造难度。
同时，本揭示实施例还提供一种显示装置，如图6所示，图6为本揭示实施例的显示装置示意图。其中，显示装置600内包括有本揭示实施例提供的识别模组601。
以上对本揭示实施例所提供的一种识别模组和显示装置进行了详细介绍，以上实施例的说明只是用于帮助理解本揭示的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，而这些修改或者替换，并不使相应技术方案的本质脱离本揭示各实施例的技术方案的范围。
