具体实施方式
为了使得本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
为了保持本公开实施例的以下说明清楚且简明，本公开省略了已知功能和已知部件的详细说明。
相关技术中，结合图1所示，对于液晶显示屏，具体可以包括显示模组010，位于显示模组010出光侧的封装盖板07，以及位于显示模组010的背离封装盖板07一侧的背光源09；显示模组010具体可以包括相对设置的彩膜基板001和阵列基板002，以及位于彩膜基板001和阵列基板002之间的液晶层05；其中，彩膜基板001具体可以包括第一衬底基板021，位于第一衬底基板021的背离封装盖板07一侧的指纹识别构件03，位于指纹识别构件03的背离封装盖板07一侧的彩膜层(彩膜层具体可以包括红色色阻041、绿色色阻043、蓝色色阻042)，以及位于第一衬底基板021的面向封装盖板07一侧的第一偏光片061；阵列基板002具体可以包括第二衬底基板011，位于第二衬底基板011背离彩膜基板001一侧的第二偏光片062。即，将指纹识别构件 03做在彩膜基板001，背光源09发出的光经过显示模组010、封装盖板07后被用户的手指指纹反射回指纹识别构件03，从指纹峰和指纹谷反射回的光强存在差异，利用该光强差异，通过指纹识别构件03的光电转换可以实现指纹识别。结合图1所示，普通的指纹识别构件03，由于背光源09发出的光经过较长的传输路径后，照射到指纹识别构件03上时，光的发散角度较大，致使指纹峰和谷反射回的光斑(条纹状)在指纹传感器上不能清晰的分开，从而会造成识别能力的下降。
基于此，参见图2和图7所示，本发明实施例提供一种显示面板，其中，包括：
显示模组100，显示模组100包括指纹识别构件3；
封装盖板7，封装盖板7位于显示模组100的出光侧，例如，如图2所示，显示模组100的上方为出光侧，则封装盖板7可以位于显示模组100的上方，出光侧具体可以为用户在使用该显示面板时所观看显示画面的一侧，封装盖板7具体可以为玻璃盖板；
多个光路调整器件8，光路调整器件8位于封装盖板7与指纹识别构件3之间，每一光路调整器件8包括：相对设置的光纤结构81和凸透镜结构82，凸透镜结构82位于光纤结构81的背离封装盖板7的一侧；光路调整器件8被配置为对入射的手指反射光进行调整，以使进入指纹识别构件3的光的发散角减小。
本公开实施例中，通过在封装盖板7与指纹识别构件3之间设置光路调整器件8，而该光路调整器件8可以对入射到该光路调整器件8的手指反射光进行光路调整，以使进入指纹识别构件的光的发散角减小，如图3所示，即，可以将原来入射到指纹识别构件3较为发射的光的发散角度减小，进而可以改善由于光的发散角度较大，致使指纹峰和谷反射回的光斑(条纹状)在指纹识别构件3上不能清晰的分开，从而导致指纹识别能力的下降的问题。
在具体实施时，结合图2所示，本公开实施例提供的显示面板可以为液晶显示面板。显示模组可以包括相对设置的彩膜基板110和阵列基板120，位 于彩膜基板110和阵列基板120之间的液晶层5，位于彩膜基板110的背离阵列基板120一侧的第一偏光片61，位于阵列基板120的背离彩膜基板110一侧的第二偏光片，以及位于显示模组100的背离封装盖板7一侧的背光源9；彩膜基板110可以包括衬底21，位于衬底基板21面向阵列基板120一侧的彩膜层(彩膜层具体可以保护红色色阻41、绿色色阻43、蓝色色阻42)；阵列基板120具体可以包括第二衬底11(彩膜基板110的衬底21具体可以作为第一衬底)，以及位于第二衬底11背离彩膜基板110一侧的第二偏光片62。
在具体实施时，对于光路调整器件8的位置，其具体可以是集成于封装盖板7，也可以集成于显示模组100内，以下通过具体举例进行说明。
例如，参见图2所示，光路调整器件8集成于封装盖板7，具体的，光路调整器件8集成于封装盖板7的面向显示模组100的一侧。即，在具体制作时，可以在封装盖板7上形成光路调整器件8，之后将形成有光路调整器件8的封装盖板7与显示模组100进行贴合。本公开实施例中，光路调整器件8集成于封装盖板7的面向显示模组100的一侧，由于指纹识别构件3位于显示模组100内，进而可以使光路调整器件8位于手指与指纹识别构件3之间的光路上，而且，相比于将光路调整器件8集成于显示模组100内，由于显示模组100本身需制作的结构较多(例如，显示模组100内需制作像素电极、公共电极、晶体管以及彩膜层)，而封装盖板7本身需制作的结构较少，可以为光路调整器件8提供较多的设置空间，不需要较大程度地变动显示面板的其它结构，制作较为方便。而且，相比于将光路调整器件8制作于封装盖板7的背离显示模组100的一侧，即，封装盖板7的外表面，本公开实施例中的将光路调整结构8制作于封装盖板7的面向显示模组100的一侧，可以避免在显示面板的使用过程中，对光路调整结构8产生较大的磨损，影响光路调整器件8的光调整准确性。
又例如，参见图4所示，将光路调整器件8集成于显示模组100内，具体的，光路调整器件8集成于彩膜基板110，具体集成于彩膜基板110的衬底21的背离阵列基板120的一侧，也即面向封装盖板7的一侧。具体的，彩膜 基板110包括衬底21，光路调整器件8具体可以集成于衬底21与第一偏光片61之间。即，在具体制作时，可以在彩膜基板110的衬底21的一侧形成光路调整器件8，之后在光路调整器件8的背离衬底21的一侧贴附第一偏光片61。
在具体实施时，本公开实施例中的指纹识别构件3可以为全屏指纹识别构件，在显示面板的任一位置均可以实现指纹识别。具体的，指纹识别构件3包括多个呈阵列分布的识别器件30，多个光路调整器件8呈阵列分布，识别器件30在封装盖板7的正投影与至少一个光路调整器件8在封装盖板7的正投影存在交叠区域。具体的，结合图5所示，识别器件30与光路调整器件8一一对应，识别器件30在封装盖板7的正投影与一个光路调整器件8在封装盖板7的正投影存在交叠区域，即，若识别器件30和光路调整器件8的大小相差不大时，识别器件30和把光线的发散角度收窄的光路调整器件8可以一一对应。或者，在具体实施时，结合图6所示，也可以是一个识别器件30对应多个光路调整器件8，识别器件30在封装盖板7的正投影与多个(图5中为三个)光路调整器件8在封装盖板7的正投影存在交叠区域，即，若识别器件30面积远大于一个光线收窄的光路调整器件8的面积，可以采用一个识别器件30对应多个光路调整器件8，使识别器件30上更多的是发散角较小的光线。
在具体实施时，结合图7所示，光纤结构81的出光口的中心与凸透镜结构82的焦点重叠。本公开实施例中，每一光路调整器件80包括相对设的光纤结构81和凸透镜结构82，对于经手指反射的光，先经过光纤结构81，之后再进入凸透镜结构82，通过控制光纤结构81与凸透镜结构82的位置关系，可以使入射到光路调整器件80的光以平行光输出或近似于平行光输出。光纤结构81的设置，可以对入射到光路调整器件的不同方向的光进行收集，并在其内进行全反射，以对光进行集中并低损耗传输。当然，在具体制作时，由于工艺误差，要满足光纤结构81的出光口的中心与凸透镜结构82的焦点精确重叠较为困难，因此，本公开实施例中的光纤结构81的出光口的中心与凸透镜结构82的焦点重叠，也可以理解为光纤结构81的出光口的中心与凸透 镜结构82的焦点的位置差距在预设范围内，均可以理解为二者重叠。
在具体实施时，光纤结构81与凸透镜结构82之间还具有第一保护层83。即，在具体实施时，可以先形成光纤结构81，之后在光纤结构81的表面形成第一保护层83，之后，再形成凸透镜结构82，具体的，第一保护层83的折射率小于光纤结构81、凸透镜结构82的折射率。本公开实施例中，光纤结构81与凸透镜结构82之间还具有第一保护层83，可以对光纤结构81进行保护，而且，第一保护层83的折射率小于光纤结构81的折射率，可以使光线能在里面发生全反射，并一直在光纤结构81里面传输；第一保护层83的折射率小于凸透镜结构82的折射率，可以使凸透镜结构82具有汇聚光线的功能。
在具体实施时，对于本公开实施例中的指纹识别构件3，其可以集成于彩膜基板110，也可以集成于阵列基板120，以下通过具体举例进行说明。
例如，参见图2和图8所示，其中，图8给出了具体的指纹识别构件3的结构分布示意图，指纹识别构件3位于衬底21与彩膜层之间。即，本公开实施例中，指纹识别构件3集成于彩膜基板110上，且位于彩膜基板110的衬底21与彩膜层之间，在具体制作时，可以先通过掩膜版、曝光、显影、蚀刻等工艺制作完成指纹识别构件3的制作，之后，制作红、绿、蓝色阻、黑矩阵、柱状隔垫物，完成彩膜基板110的制作。
具体的，指纹识别构件3集成于彩膜基板110上时，指纹识别构件3具体可以包括位于衬底21之上的用于驱动指纹识别构件3的第一晶体管300，以及位于第一晶体管300的背离衬底基板21一侧的识别器件30；第一晶体管300可以包括依次位于衬底21之上的遮光层31、第一绝缘层22、有源层32、第二绝缘层23、栅极33、第三绝缘层24、源漏极层(具体可以包括源极34以及漏极35)、第四绝缘层25；识别器件30可以包括依次位于第四绝缘层25背离源漏极层一侧的第二电极36、光敏膜层37、第一电极38；彩膜基板110在第一电极38的背离识别器件30的一侧还可以依次设置有平坦层26、第三电极391、第五绝缘层27。第五绝缘层27背离识别器件30一侧可以设置红色设置41、绿色色阻42、蓝色色阻43以及黑矩阵44。识别器件30具体可以 位于相邻色阻之间，即，位于黑矩阵44所在位置处，以避让像素所在位置，进行正常显示。其中，第二电极36可以通过贯穿第四绝缘层25的过孔与源漏极层中的源极或漏极之一进行电连接；第三电极391可以通过贯穿平坦层26的过孔与第一电极38电连接，第三电极391具体可以为向第一电极38提供电信号的信号线。对于阵列基板120，阵列基板120可以包括第二衬底基板11，依次位于第二衬底基板11面向彩膜基板110一侧的公共电极12(该公共电极12复用作触控发射电极)，第六绝缘层13、像素电极14；阵列基板120在第二衬底基板11的背离彩膜基板110的一侧还可以设置有第二偏光片62，该第二偏光片62具体可以与彩膜基板110的偏光片61(也即第一偏光片)的偏振方向相互垂直。彩膜基板110与阵列基板120之间设置有液晶层5。显示模组100的背离封装盖板7的一侧具体还可以设置有背光源9，手指反射的光具体可以为由背光源9照射到手指的光。
又例如，参见图9所示，指纹识别构件3集成于阵列基板110，具体的，指纹识别构件3集成于阵列基板120的面向彩膜基板110的一侧。
具体的，结合图9所示，指纹识别构件3集成于阵列基板120时，阵列基板120具体包括依次位于第二衬底基板11之上用于驱动识别器件30的晶体管300，以及位于晶体管300的背离衬底基板00一侧的识别器件30；其中，晶体管300可以包括依次位于第二衬底基板11之上的第一绝缘层22、有源层32、栅极层(栅极层具体可以包括栅极33、发射电极15、接收电极16)、第二绝缘层23、源漏极层(具体可以包括源极34和漏极35)、第三绝缘层24；识别器件30可以包括依次位于第三绝缘层24之上的第二电极36、光敏膜层37、第一电极38；阵列基板120在第一电极38的背离光敏膜层37的一侧还可以依次设置有平坦层25、第三电极391、第四绝缘层26、公共电极12、第五绝缘层27、像素电极14。彩膜基板110具体可以设置有衬底基板21(也即第一衬基板)，位于衬底基板21的面向阵列基板120一侧的红色色阻41、绿色色阻42、蓝色色阻43。显示模组100在彩膜基板110与阵列基板120之间还可以设置有液晶层5，彩膜基板110的背离阵列基板120的一侧还可以设置 有第一偏光片61，阵列基板120的背离彩膜基板110的一侧还可以设置有第二偏光片62。显示模组110在背离封装盖板7的一侧还可以设置有背光源9。
