背景技术
随着用户对于高屏占比终端的外观美学和视觉感观的体验需求，全面屏移动终端已经逐渐成为一种发展趋势，并逐步面向市场。为提升移动终端的整机屏占比及其美观性，屏下指纹识别和面部识别等解决方案逐步出现。
相关技术中的屏下指纹识别方案的一种研发思路是配合有机发光二极管(Organic Light-Emitting Diode，OLED)屏幕来实现屏下光学指纹识别，这种方案主要是利用屏幕的OLED发射光源，然后发射光线经过手指反射给指纹模组的感应装置进行指纹检测识别。但是，这种方案由于是利用OLED发光来实现指纹识别，其识别率较低，并且难以做到只对指纹区域进行发光，导致耗电量较大；另外，为了提高指纹识别率，需要提高OLED的发光亮度，从而导致耗电量加大，同时也会因强烈的发光亮度导致用户强光刺眼的感受，造成不良好的使用体验。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
请参见图1和图2，本公开实施例提供一种屏幕组件，可以包括：
显示面板110；

红外感光模组120，红外感光模组120设于显示面板110的另一侧，红外感光模组用于接收红外光源模块130发射的红外光照射于目标体之后反射至红外感光模组120形成的反射光。
本公开实施例中，通过将红外光源模块130设置于显示面板110，能够为设于显示面板110下方的红外感光模组120提供红外光以用于红外感光模组实现感光检测，这样，能够达到红外感光模组120屏下识别检测的目的；另外，利用红外光源模块130提供红外光，能够避免相关技术中利用显示面板110直接全屏发光造成耗电量较大且导致强光刺眼的问题，达到降低耗电并提升红外感光模组120的检测识别率的效果。
本公开实施例中，显示面板110可以为OLED显示面板，该显示面板110的基本结构是由一薄而透明具半导体特性的铟锡氧化物(ITO)与电力之正极相连，然后再加上另一个金属阴极从而包成如三明治的结构，该结构使得该显示面板110内能够埋设红外光源模块130，因此，在本公开可选的实施例中，该红外光源模块130可以设于显示面板110的内部，结构紧凑，利于减小屏幕组件的厚度，实现轻薄化。
具体地，如图1和图2所示，屏幕组件启动红外光源模块130和红外感 光模组120，通过红外光源模块130发射红外光，其发射的红外光(该发射的红外光如图1和图2中所示意的带有箭头的实线)投射至目标体后形成反射光(该反射光可以包括发射光线和散射光线，即如图1和图2中所示意的带有箭头的虚线)，并反射至红外感光模组120，该红外感光模组120接收该反射光并根据该反射光生成检测信息。
其中，如图4所示，该目标体可以为手指，或者，如图6所示，该目标体也可以为人脸，或者，该目标体还可以为包括场景或其他物体等拍摄对象，该目标体的具体认定可以基于红外感光模组120的具体类型或具体用途进行设置。可选地，本公开实施例中，红外感光模组120可以为指纹识别模组121、面部识别模组和红外摄像模组122中的至少一个。
在本公开一个可选的实施例中，该红外感光模组120包括指纹识别模组121，该指纹识别模组121与红外光源模块130的设置位置相对应，其中，红外光源模块130发射的红外光在显示面板110上的照射区域覆盖指纹识别模组120的指纹识别区域，其中，如图3、图5和图6所示，标号为A1的方框区域所示意的是指纹识别模组121的指纹识别区域，标号为A2的方框区域所示意的是红外光源模块130发射的红外光在显示面板110上的照射区域。在具体应用中，指纹识别模组121的指纹识别区域以及红外光源模块130发射的红外光在显示面板110上的照射区域可以为多种设置形状，例如圆形、椭圆形、心形或星型等，其可以根据实际结构设计、效果需求等进行具体设置。
本公开实施例中，红外光源模块130可以埋设于显示面板110内部，且该红外光源模块130的设置位置与指纹识别模组121相对应，从而能够通过红外光源模块130为指纹识别模组121提供红外光用于指纹识别，这样，能够达到屏幕组件屏下指纹识别的目的，并且利用红外光源模块130为指纹识别模组121提供红外光，能够提升指纹识别率并降低耗电，同时能够避免相关技术中指纹识别时存在强光刺眼的问题。
具体地，如图4所示，在检测到指纹识别区域内有手指接触时，屏幕组件启动红外光源模块130和指纹识别模组121，通过红外光源模块130发射红外光，其发射的红外光(该发射的红外光如图4中所示意的带有箭头的实 线)投射至目标体后形成反射光(该反射光可以包括发射光线和散射光线，即如图4中所示意的带有箭头的虚线)，并反射至指纹识别模组121，该指纹识别模组121接收该反射光并根据该反射光生成检测信息，并传输至处理器进行指纹识别。
在本公开一个可选的实施例中，如图4所示，指纹识别模组121可以包括：红外指纹传感器1211，从而能够通过该红外指纹传感器1211接收和处理红外光源模块130投射于手指后反射形成的发射光，以实现指纹识别。另外，该指纹识别模组120还可以包括透镜1212，红外光源模块130发射的红外光投射于手指后经发射形成反射光，其包括反射光线或散射光线，反射光线或散射光线经过透镜1212，按照透镜成像原理折射到红外指纹传感器1211，以使红外指纹传感器1211接收并处理。
如图3、图5和图6所示，在本公开一个可选的实施例中，红外感光模组120包括红外摄像模组122，用于接收红外光源模块130照射于目标体(被摄物体)的发射光所形成的反射光，并处理成像。本公开实施例中，该红外摄像模组122能够与红外光源模块130配合实现摄像，以实现红外拍摄；另外，在一些实施例中，该红外摄像模组122可以用于实现人脸识别功能。可选地，该红外摄像模组122包括红外摄像头。
在本公开一些可选的实施例中，该红外感光模组120可以同时包括指纹识别模组121、面部识别模组和红外摄像模组122中的至少两个，这样，能够实现多种类型的红外感光模组120共用同一发射光源。
如图6所示，红外感光模组120同时包括指纹识别模组121和红外摄像模组122，能够使屏幕组件的屏下指纹识别与红外拍摄共用同一发射光源，从而能够取消原有用于红外拍摄的红外发射组件，节省器件设置空间，减小制造成本。
有利地，如图5所示，本公开实施例中，指纹识别模组121与红外摄像模组122之间的距离小于一预设值。该预设值可以基于红外光源模块130的发射光的发射角度和发射距离等设置需求进行具体设置，这里，该预设值的设置需要至少确保红外光源模块130发射的红外光能够照射于预定范围内的被摄物体且能够使红外摄像模组122接收到照射于被摄物体的红外光所形成 的发射光。如图5所示，在一示例中，该预设值可以为屏幕组件的长度方向的长度的1/2，这样，能够使该指纹识别模组121的指纹识别区域位于屏幕组件的中部，从而能够确保红外摄像模组122与红外光源模块130配合实现摄像，并且能够也便于用户指纹识别操作，尤其是在较大尺寸的屏幕组件，能够更便于用户触摸指纹识别区域。
在本公开一个可选的实施例中，如图4所示，该红外光源模块130可以包括：多个红外发光二极管131，多个红外发光二极管131与显示面板110的LED发光组件间隔设置。本公开实施例中，通过将多个红外发光二极管131与LED发光组件间隔设置，能够确保红外发光二极管131和LED发光组件不会相互影响，即能够确保屏幕组件的红外感光模组120的功能实现的同时不会影响显示面板110正常成像。
可选地，本公开实施例中，多个红外发光二极管131与显示面板110的像素单元111间隔设置，利于实现合理布局，可以节约空间成本。
本公开实施例中，多个红外发光二极管131在显示面板110中的具体排布方式可以基于实际结构设计、红外光发射效果等进行设置。可选地，本公开实施例中，如图3和图5所示，多个该红外发光二极管131呈多行等距排布；或者，多个该红外发光二极管131呈矩阵排列方式排布。
另外，本公开实施例中，多个红外发光二极管131的数量和位置分布同样可以根据实现效果设置。
可以理解的是，在本公开实施例中，若需要提高红外感光模组的接收强度，或者，适应不同类型的红外感光模组的接收强度，只需通过调节红外光源模块130发射红外光的发射强度即可，这样能够有效避免相关技术中强光刺眼的现象，并且能够降低耗电，延长续航时间。
在本公开的一些实施例中，红外光源模块130具有驱动组件，驱动组件与多个红外发光二极管131连接，用于启动多个红外发光二极管131，并调节多个红外发光二极管131的发射强度。通过驱动组件能够更好地控制多个红外发光二极管131，并使多个红外发光二极管131可以根据实际需要调节至合适的发射强度，满足用户的多种使用需求。
需要说明的是，红外光源模组130可以针对不同类型的红外感光模组120 设置相适应的发射强度，即针对调用的红外感光模组120为指纹识别模组121、面部识别模组或红外摄像模组122时，驱动组件可以调节多个红外发光二极管131的发射强度至相适应的发射强度值。
举例而言，若红外感光模组120包括指纹识别模组121，在调用指纹识别模组121时，驱动组件将多个红外发光二极管131的发射强度调节至第一预设强度值；若红外感光模组120包括面部识别模组，在调用面部识别模组时，驱动组件将多个红外发光二极管131的发射强度调节至第二预设强度值；若红外感光模组120包括红外摄像模组122，在调用红外摄像模组122时，驱动组件将多个红外发光二极管131的发射强度调节至第三预设强度值；其中，第一预设强度值小于第二预设强度值，第三预设强度值大于或等于第二预设强度值。
另外，在本公开一个实施例中，如图1所示，至少部分红外感光模组120在显示面板110上的正投影位于红外光源模块130在显示面板110上的正投影的范围内。例如，在一示例中，该红外感光模组120包括指纹识别模组121，如图4所示，该指纹识别模组121在显示面板110上的正投影可以全部或部分位于红外光源模块130在显示面板110上的正投影的范围内。
在本公开另一个实施例中，如图2所示，红外感光模组120在显示面板110上的正投影与红外光源模块130在显示面板110上的正投影间隔设置。例如，在一示例中，该红外感光模组120包括红外摄像模组122，如图3、图5和图6所示，该红外摄像模组122在显示面板110上的正投影与红外光源模块130在显示面板110上的正投影间隔设置，其中，两者之间的间隔距离可以根据实际设计需求进行设置。
请参见图1、图2和图4，在本公开一个实施例中，屏幕组件还可以包括：中框结构150，贴合设置于显示面板110上与红外光源模块130发射红外光方向相反的另一侧。本公开实施例中，该中框结构150贴合设置于显示面板110，能够起到对显示面板110的支撑作用。
可选地，在本公开实施例中，为确保红外感光模组120的光线接收不受影响，该中框结构150上对应红外感光模组120的区域设置有开孔。需要说明的是，该开孔的大小应满足预设要求，以使其至少确保红外感光模组120能 够接收到预定区域(如指纹识别模组121的指纹识别区域)内反射或散射的反射光。
本公开实施例提供的屏幕组件，通过设置于显示面板的红外光源模块为设于显示面板下方的红外感光模组提供红外光以用于红外感光模组实现感光检测，这样，能够达到红外感光模组屏下识别检测的目的，并且能够避免相关技术中利用显示面板直接发光造成耗电量较大且导致强光刺眼的问题，可以降低耗电并提升红外感光模组的检测识别率。
另外，本公开实施例还可以提供一种电子设备，包括上述的屏幕组件。
其中，电子设备还可以包括诸如听筒、扬声器、麦克风以及用于容置各个部件的壳体等等一系列基本部件，本公开实施例中对此不再一一赘述。
