本申请实施例提供了一种电子设备，本申请电子设备可以是任何具备通信、显示和存储功能的设备，例如平板电脑、手机、电子阅读器、遥控器、个人计算机(Personal Computer，PC)、笔记本电脑、车载设备、网络电视、可穿戴设备等设备。
本申请实施例的电子设备可以包括显示组件和壳体，其中显示组件包括显示屏。如图1所示，电子设备10的显示屏12安装在壳体11上。显示屏12可以包括采用贴合工艺贴合在一起的盖板及显示面板，其中盖板可以仅具有防护显示面板的功能，显示面板兼具有显示功能和触控功能；或者盖板可以兼具防护功能与显示功能，而显示面板仅用于显示。本申请的实施例中，显示面板可以是自发光显示面板，如OLED(Organic Light-Emitting Diode, 有机发光二极管)面板、等离子显示面板，或电子墨水显示面板等；显示面板也可以是液晶面板。或者，显示屏12可以是一种加强型的显示面板，其显示面具有较高的机械性能(如硬度和强度)，能够承受外界的冲击、摩擦、按压、损伤等。
图2示出了本申请第一实施例的电子设备10中的显示组件。如图2所示，显示组件包括显示屏12、聚光层21，以及若干个感光单元22，显示屏12、聚光层21，以及若干个感光单元22依次层叠。在一种实施方式中，以显示屏12为自发光显示屏12(即显示屏12包括相贴合的盖板及自发光显示面板，或者显示屏12为加强型的自发光显示面板)为例进行描述。
如图2和图3所示，在一种实施方式中，显示屏12具有阵列排布的多个像素121，每个像素121用于在驱动下发光以使显示屏12显示各种画面。显示屏12中的像素121可以呈矩阵排列，也可以根据需要排列成特定的图案。任意两个相邻的像素121之间均具有间隔。以图3为例，间隔不仅存在于的水平方向或竖直方向的任意两个相邻的像素121之间，也存在于斜对角方向上的任意两个相邻的像素121之间。在显示屏12的制程中(例如显示面板的制程)，间隔内可形成具有特定功能(包括但不限于分隔不同像素121以防止像素121间串光)的膜层，此膜层能够透光(也即间隔能够透光)。如图3所示，间隔可以包括第一间隔122，第一间隔122的数目可以是至少一个，第一间隔122的设计特点将在下文继续描述。
如图2和图3所示，聚光层21上开设有多个微通孔211，微通孔211的数目与生物特征信息的采集有关，以能准确进行生物特征信息的采集为准进行设置。微通孔211的孔轴为直线，且与显示屏12的厚度方向基本一致。微通孔211的孔径小于间隔的尺寸，微通孔211的孔径数值达到微米级。微通孔211的形状可以根据需要设计，包括但不限于为方孔、圆孔等。聚光层21上的全部微通孔211中存在至少两个这样的微通孔211：该至少两个微通孔211的一端开口对准第一间隔122，相对的另一端开口对准同一个感光单元22。在一种实施方式中，微通孔211的开口对准间隔的含义为：微通孔211的开口在显示屏12上的正投影落在间隔之内(也即微通孔211在显示屏12上的正投影落在间隔之内)；微通孔211的开口对准感光单元22的含义为：微通孔211的开口在感光单元22上的正投影落在感光单元22的感光面之内(也即微通孔211在感光单元22上的正投影落在感光单元22的感光面之内)。
也就是说，所述聚光层21位于所述显示屏12和所述若干个感光单元22之间，所述显示屏12具有阵列排布的多个像素，任意两个相邻的所述像素121之间具有间隔，所述间隔包括第一间隔122；所述聚光层21上开设有多个微通孔211，至少两个所述微通孔211的开口方向朝向所述第一间隔，且至少两个所述微通孔211的开口方向朝向同一个所述感光单元22。
在一种实施方式中，微通孔211用于供光线穿过。对于第一间隔122而言，至少两个微通孔211与第一间隔122对准，即第一间隔122涵盖了至少两个微通孔211，因此透过第一间隔122的光线能够穿过该至少两个微通孔211，照射到同一个感光单元22上。显示屏 12上的各个间隔可以均为第一间隔122，也可以包括除第一间隔122之外的其他间隔，该其他间隔可以不对准微通孔211与感光单元22，即该其他间隔内传输的光线无法通过微通孔211照射到感光单元22上；或者该其他间隔可以仅对准一个微通孔211与感光单元22，因此穿过该其他间隔的光线也能够穿过该微通孔211，照射到该感光单元22上。
在一种实施方式中，感光单元22用于感应光线(即进行光电转换)以生成感测信号。感光单元22的数量与生物特征信息的采集有关，以能准确进行生物特征信息的采集为准进行设置。各感光单元22间隔分布，一个感光单元22与若干个(如至少一个，或至少两个)微通孔211对准，以从微通孔211中接收光线。每个感光单元22可以进行封装，以形成一个较为独立的功能单元。各个感光单元22可以设在基板23上，基板23位于聚光层21背离显示屏12的一侧，各个感光单元22具体形成在基板23朝向聚光层21的一面。基板23作为感光单元22的承载衬底，其还具有导电性能，能够与各感光单元22进行电信号交互。当然，也可以不限于设计基板23，而是依靠其他结构承载并电连接各感光单元22。
在一种实施方式中，聚光层21与感光单元22可以分布在显示屏12的全部显示区内，此时显示屏12的全部显示区均可以感应光线；聚光层21与感光单元22可也可以仅在显示屏12的部分显示区有分布，此时显示屏12仅有部分显示区可感应光线。
在一种实施方式中，电子设备10能够利用显示组件采集待识别对象(需要进行身份识别的对象)的生物特征信息(包括但不限于为指纹信息、掌纹信息、面部特征信息、虹膜图像信息等)，进行生物特征信息的识别，完成对待识别对象的身份认证。以下将以待识别对象为人，生物特征信息为指纹信息为例详细描述生物特征信息采集的过程。
如图4所示，显示屏12在显示画面时发光。当手指接近显示屏12时(可以是手指贴合显示屏12，或者手指到显示屏12的距离小于或等于感应距离)，显示屏12的发光照射到手指后形成反射光，该反射光将射入显示屏12内，并进入像素121的间隔传输。其中，进入第一间隔122的反射光将穿过与第一间隔122对准的微通孔211(与第一间隔122对准的全部微通孔211，或者与第一间隔122对准的全部微通孔211中的若干微通孔211)，照射到感光单元22上。
在上文的光线传输过程中，显示屏12的像素121间隔作为反射光的传输介质。聚光层21与感光单元22的设计利用了类似“小孔成像”的原理实现反射光成像。其中，聚光层21上的微通孔211类似“小孔成像”原理中的小孔，感光单元22类似“小孔成像”原理中的成像屏。反射光穿过微通孔211后被聚集到感光单元22上，感光单元22则感应光线生成感测信号，该感测信号携带了手指的指纹信息(即指纹图像)，从而完成指纹信息的采集。
在一种实施方式中，电子设备10可以包括存储器和处理器，存储器预存有目标指纹信息(用户输入的原始指纹信息)，处理器用于将该感测信号中携带的指纹信息与目标指纹信息进行比较以对该指纹信息进行识别。若该指纹信息与该目标指纹信息匹配时，则通过待识别对象的身份认证，此时处理器可驱动显示屏12显示相应的第一画面(如解锁画面、支付成功画面等)；若不匹配，则待识别对象的身份认证失败，此时处理器可驱动显示屏 12显示相应的第二画面(如解锁失败提示画面、支付失败提示画面等)。
如上，感光单元22也可以采集除指纹信息之外的生物特征信息。相应的，存储器可预存有除目标指纹信息之外的目标特征信息(如输入的原始掌纹信息，原始面部特征信息，原始虹膜图像信息等)；处理器则用于将该感测信号中携带的生物特征信息与目标特征信息进行比较，以对该生物特征信息进行识别，并在待识别对象的身份认证通过与失败时，分别驱动显示屏12显示不同的画面。
在一种实施方式中，当显示屏12的全部显示区均可以感应光线(即聚光层21与感光单元22分布在显示屏12的全部显示区内)时，显示屏12的全部显示区均可以作为生物特征识别区，由此待识别对象可以在显示区的任意区域进行生物特征识别；当显示屏12仅有部分显示区可感应光线(即聚光层21与感光单元22仅在显示屏12的部分显示区有分布)时，仅仅是显示屏12的部分显示区可以作为生物特征识别区，因此待识别对象可以在显示区的部分区域进行生物特征识别。对于后一种方案，可以对待识别对象发出提示，使其能够清楚地辨识出生物特征识别区。例如，可以在显示区内显示一提示画面，以提示待识别对象在此区域内进行生物特征识别；或者可以将显示区内的特定区域固设为生物特征识别区(如定义二分之一或三分之一的显示区为生物特征识别区)，并在电子设备10的产品说明中告知待识别对象。
另外，本第一实施例的方案还能够改善指纹图像的莫尔条纹缺陷及固定噪声缺陷。具体的，参照图4所示，聚光层21与显示屏12的生产及组装均可能出现偏差(应理解，此组装偏差会控制在一定范围内)，使聚光层21与第一间隔122错位。此时，原本对准第一间隔122的各个微通孔211中，可能有若干微通孔211不再对准第一间隔122。但是由于第一间隔122涵盖了至少两个微通孔211，因此存在至少一个微通孔211依然与第一间隔122对准的可能性。在实际产品中，微通孔211的孔径远小于第一间隔122的尺寸，即使聚光层21与第一间隔122错位，但与第一间隔122对准的微通孔211数目会很多，这些与第一间隔122对准的微通孔211又与同一个感光单元22对准，使该感光单元22能够感应这些微通孔211所传输的光线。由此，在出现错位时对应第一间隔122的感光单元22也能正常感应光线，使得经过处理后得到的指纹图像清晰准确，不会出现莫尔条纹和固定图像噪声。反之，若间隔仅对准一个微通孔211，且此微通孔211对准一个感光单元22，在间隔与微通孔211错位时，就无法满足“小孔成像”的清晰成像条件，导致感光单元22无法正常感应光线，经过处理后得到的指纹图像就会出现莫尔条纹和固定图像噪声。
综上，本第一实施例的方案既能够利用显示屏12的像素121区(即显示区)实现生物特征采集和识别，从而将生物特征识别功能集成在电子设备10的显示区内。相较于传统的电子设备10，本第一实施例的方案能够扩大显示区，而使非显示区相对缩小，从而提升了电子设备10的屏占比。并且，由于在显示屏12下进行生物特征采集，无需在显示屏12中开孔，因此保证了显示屏12的结构强度及电子设备10的外观完整性。另外，本第一实施例的方案还能改善甚至消除莫尔条纹缺陷及固定噪声缺陷。
如图2、图3和图5所示，在一种实施方式中，进一步的，像素121的间隔还可以包 括第二间隔123，第二间隔123的数量为至少一个。第二间隔123可与至少一个微通孔211对准，且与第二间隔123对准的微通孔211对准同一个感光单元22。第二间隔123也用于透过该反射光，与第二间隔123对应的感光单元22同样用于感应反射光生成感测信号。由上所述，当第二间隔123仅与一个微通孔211对准时(如图2与图3所示)，若聚光层21与第二间隔123出现错位，此时第二间隔123处的生物特征图像会出现莫尔条纹和固定图像噪声，但是第二间隔123依然可以用于成像。第一间隔122处所形成的生物特征图像仍然能够保证质量，因此整体上本第一实施例的方案依然改善了莫尔条纹缺陷及固定噪声缺陷。当第二间隔123与至少两个微通孔211对准时(如图5所示)，此时第二间隔123与第一间隔122等同，第二间隔123与第一间隔122均涵盖至少两个微通孔211。由此，在聚光层21与显示屏12错位时，第一间隔122处与第二间隔123处所形成的指纹图像均能消除莫尔条纹缺陷及固定噪声缺陷。
在一种实施方式中，进一步的，显示屏12的像素121间的任意一个间隔均与至少两个微通孔211对准，且与同一个间隔对准的全部微通孔211均对准同一个感光单元22。即此时全部间隔均为第一间隔122，且显示屏12全部显示区均可以作为生物特征识别区。由此不仅优化甚至消除了莫尔条纹问题与固定噪声问题，还能实现全屏生物特征识别。
如图2和图4所示，在一种实施方式中，感光单元22具有感光面(即用于接收光线的面)。优选的，与感光单元22对应的间隔在感光面上的正投影落在感光面之内。由此，感光单元22具有更大的感光面积，能够实现更大视野范围的生物特征图像采集。当然，也可以不限于此，只要感光单元22能感应到穿过间隔传输至感应面的光线即可。
在一种实施方式中，进一步的，聚光层21到显示屏12的距离可以调节。其内在机理为，调整聚光层21到显示屏12的距离相当于调整物距，因此成像视野、成像大小、成像清晰度等可以相应调整，从而适应不同的识别场景(如不同的待识别对象，待识别对象所处的不同光照环境等)。可以设计调节结构调整聚光层21到显示屏12的距离。当然，聚光层21到显示屏12的距离也可以为固定值。
在一种实施方式中，可以通过进一步的光学设计，提升感光单元22所采集的生物特征图像的质量。
具体的，如图6所示，在第一实施方式中，显示屏12与若干个感光单元22之间可以设置第一光学层24，第一光学层24与聚光层21层叠设置。第一光学层24用于滤除特定波段的不可见光，该不可见光包括但不限于红外光。图5中第一光学层24具体设于显示屏12与聚光层21之间，当然第一光学层24也可以设于聚光层21与若干个感光单元22之间；或者显示屏12与聚光层21之间，以及聚光层21与若干个感光单元22之间均可以设置第一光学层24。第一光学层24可以覆盖聚光层21上的全部微通孔211(此覆盖适用于第一光学层24位于聚光层21之上、之下或上下两侧三种情形)。设置第一光学层24的意义在于，当待识别对象贴合显示屏12进行生物特征识别(指纹识别或掌纹识别)时，环境光中的可见光无法穿透待识别对象的手指或手掌，但一些特定波段的不可见光却能够透过待识别对象的手指或手掌，穿过间隔和通孔，照射到感光单元22上而被感应，该不可见光会干 扰感光单元22对显示屏12的发光的感应，进而影响生物特征图像的质量。当增设第一光学层24后，第一光学层24对环境光中的不可见光进行过滤，从而排除了不可见光的干扰，确保了生物特征图像的质量。
如图6所示，进一步的，第一光学层24朝向或背离显示屏12的表面可以镀覆有第一镀膜，第一镀膜可以覆盖第一光学层24朝向或背离显示屏12的整个表面。第一镀膜包括间隔排布的多个镀膜单元241，第一镀膜用于使透过第一光学层24射出的光线准直。由此，经过第一镀膜的准直作用，原来较为发散的光线被修整成为平行线，这有利于光线聚集到感光单元22上，从而有利于提升成像质量。
如图7所示，在第二实施方式中，显示屏12与若干个感光单元22之间可以设有第二光学层25，第二光学层25与聚光层21层叠设置。第二光学层25具有与第一镀膜类似的功能，用于使透过第二光学层25射出的光线准直。但与第一镀膜不同的是，第二光学层25为连续的膜层，其采用与第一镀膜不同的制造工艺制成。图6中第二光学层25具体设于显示屏12与聚光层21之间，当然第二光学层25也可以设于聚光层21与若干个感光单元22之间。第二光学层25可以覆盖聚光层21上的全部微通孔211(此覆盖适用于第二光学层25位于聚光层21之上或者之下两种情形)。经过第二光学层25的准直作用，原来较为发散的光线被修整成为平行线，这有利于光线聚集到感光单元22上，从而有利于提升成像质量。
如图6所示，进一步的，第二光学层25朝向或背离显示屏12的表面可以镀覆有第二镀膜，第二镀膜可以覆盖第二光学层25朝向或背离显示屏12的整个表面。第二镀膜包括间隔排布的多个镀膜单元251，第二镀膜用于使透过第二光学层25射出的光线准直。由此，通过增设第二镀膜，能够强化准直光线的作用，更加有利于光线聚集到感光单元22上，进一步提升成像质量。
在本第一实施例的其他实施方式中，上述的第一光学层24、第一镀膜、第二光学层25、第二镀膜均可以根据需要进行组合选用，只要使组合选用的光学部件(包括光学层与镀膜)位于显示屏12与感光单元22之间即可，而不限于具有上述第一实施方式与第二实施方式中所用的光学部件类型及光学部件间的相对位置。例如，如图8所示，可以在聚光层21朝向与背离显示屏12的两面均设置第一光学层24，在第一光学层24与显示屏12之间设置第二光学层25，由此既能滤除有害的不可见光，又能将光线准直。
在一种实施方式中，进一步的，显示组件还可以包括不可见光源，不可见光源设在显示屏12下方。不可见光源用于发射不可见光线，该不可见光线包括但不限于为红外光线。增设不可见光源能够在熄屏场景下实现生物特征采集和识别。具体的，处理器还用于控制不可见光源在显示屏12处于熄屏状态时发出不可见光线，不可见光线穿过像素121间的间隔，并从显示屏12的设定区域(设定区域即为生物特征识别区)中射出，该设定区域可以是显示屏12的部分显示区，也可以是全部显示区。不可见光线射出显示屏12后遇到待识别对象后发生反射，反射光线又射入显示屏12，并穿过像素121间的间隔及微通孔211照射到感光单元22上。感光单元22则可以感测不可见光线以生成感测信号，该感测信号携 带了生物特征信息，处理器对该生物特征信息进行处理，从而完成生物特征的采集和识别。可以对待识别对象发出提示，使其能够清楚地辨识出设定区域。例如，可以将显示区内的特定区域作为设定区域(如定义二分之一、三分之一，或全部显示区为设定区域)，并在电子设备10的产品说明中告知待识别对象设定区域的具体位置。由此，通过采用不可见光源，能够在熄屏时也能进行生物特征的采集和识别，从而扩充了电子设备10的功能，提升了电子设备10的用户体验。应理解，在利用不可见光线照亮手指时，可以不再设置第一光学层24，以避免将用于成像的不可见光滤除。
或者，为了实现熄屏场景下的生物特征采集和识别，在一种实施方式中也可以无需设置不可见光源，而是利用显示屏12本身的发光。具体的，在待识别对象与处于熄屏状态的显示屏12的距离达到感应距离(感光单元22能清晰成像的最大距离)时，处理器则控制显示屏12的设定区域中的像素121发光以照亮待识别对象，从而使设定区域内的感光单元22感应经待识别对象反射回来的光线。当设定区域为部分显示区时，设定区域可显示一提示图像(例如模拟指纹的图案)，以提示待识别对象在设定区域内进行生物特征识别；当设定区域为整个显示区时，待识别对象可以在显示区的任意区域内进行生物特征识别。优选的，电子设备10还可以包括检测模块，该检测模块用于检测待识别对象与显示屏12的距离，并向处理器发送指示距离的反馈信号。处理器根据反馈信号判断该距离是否达到感应距离。在判断该距离达到感应距离时，处理器驱动显示屏12的设定区域中的像素121发光，以提示待识别对象进行生物特征识别。
在一种实施方式中，显示组件还可以包括控制电路，控制电路用于驱动显示屏12进行显示。优选的，控制电路还可以控制若干个感光单元22感应光线。由此，显示屏12与感光单元22可以复用同一个控制电路，从而可以简化电路设计。当然，显示屏12与感光单元22也可以具有各自的控制电路。
以上的第一实施例中，显示屏12为自发光显示屏12。如图9所示，在本申请的第二实施例中，与上述第一实施例不同的是，显示组件30的显示屏为液晶显示屏，即显示屏包括液晶面板31和背光模组32。其中，液晶面板31具有阵列排布的多个像素311，相邻像素311间具有间隔312。背光模组32用于向液晶面板31提供背光源。背光模组32可以包括承载框体322和光学部件321，光学部件321收容在承载框体322内，光学部件321为与产生背光线相关的部件，光学部件321包括各类光学膜片(如增透膜、滤光片、反射片等)、导光板、光源等。承载框体322采用不透光材料(例如金属和/或塑胶)制造，承载框体322上开设有多个第一透光孔322a，一个第一透光孔322a与一个间隔321对准。聚光层21设于承载框体322背离液晶面板31的一侧。
本第二实施例的方案进行生物特征识别的原理，与上述第一实施例的基本相同，区别之处在于：显示屏的发光被待识别对象反射后，反射光线在穿过像素311的间隔312后，还要穿透背光模组32中的光学部件321(主要是光学膜片及导光板)及穿过承载框体322上的第一透光孔322a，然后才能穿入微通孔211，并最终被感光单元22感应。为可更有效地传输光线，背光模组32中的光学部件321可做特殊设计(包括但不限于采用新型材料)， 使其既能有利于产生背光线，又可透过显示屏的发光。例如，导光板可以具有多个透光区域(依然有材料填充，并非为通孔)，一个透光区域与一个第一透光孔322a对准，以使穿过第一透光孔322a的光线穿透透光区域照射到聚光层21中。透光区域具有高透光性，因此能使反射光线透过。可以通过抛光工艺形成透光区域。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易的想到各种等效的修改或替换，这些修改或替换都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
