下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述，显然，所描述的实施方式仅仅是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施方式，都属于本申请保护的范围。
请参阅图1，图1是本申请实施例提供的第一种显示屏组件的结构示意图。在本实施例中，所述显示屏组件10包括层叠设置的屏幕组件100和光学传感器200，所述屏幕组件100用于朝向背离所述光学传感器200的一侧发射第一光学信号，所述光学传感器200根据所述第一光学信号反射回来的第二光学信号采集目标对象的指纹图像，所述屏幕组件100内透光率小于预设透光率的部件至少部分层叠设置；或者，所述屏幕组件100还包括调节层300，所述调节层300的折射率大于预设折射率，其中，所述预设折射率等于氮气的折射率；以提高所述光学传感器200对所述指纹图像的识别精度。
其中，屏幕组件100可以为柔性显示屏。所述光学传感器200通常是指能敏感由紫外光到红外光的光能量，并将光能量转换成电信号的器件。所述光学传感器200所识别的光线信号可以为可见光或不可见光。
例如，所述光线信号为可见光，所述光学传感器200的光敏层感应到可见光时发生光电效应。例如，所述光学传感器200的光敏层可采用富硅化合物，包括但不限于富硅氧化硅(SiOx)、富硅氮化硅(SiNy)、富硅氮氧化硅(SiOxNy)等，其中x、y为正整数，比如x＝2，y＝2。所述光学传感器200的输入端采用透明导电材料。透明导电材料可以为但不限于氧化铟锡(Indium tin oxide，ITO)。光线信号穿过所述光学传感器200的输入端进入所述光学传感器200的光敏层。
当屏幕组件100为柔性显示屏时，屏幕组件100具备自发光的特性。屏幕组件100朝向背离光学传感器200的一侧发射第一光学信号，第一光学信号被按压于屏幕组件100外表侧的用户的手指遮挡后，一部分光学信号被手指产生漫反射损耗掉，另一部分携带有用户手指的指纹信息，也就是反射回来的第二光学信号，第二光学信号需要先穿过屏幕组件100，之后才能达到光学传感器200，进而被光学传感 器200接收后转化为指纹图像。当第二光学信号穿过屏幕组件100时，由于屏幕组件100内的部分器件的透光率较低，屏幕组件100内的器件的排布会对第二光学信号产生遮挡，使得第二光学信号在穿过屏幕组件100时，造成损耗。且第二光学信号在穿过屏幕组件100的各个层结构时，由于屏幕组件100的各个层结构的折射率不同，会导致第二光学信号产生不同程度的折射效果，使得第二光学信号的传输路径变长，进而引起第二光学信号产生损耗。为了解决上述问题，避免第二光学信号产生损耗，影响到光学指纹传感器采集指纹图像的清晰度，本申请一方面通过优化屏幕组件100内的器件排布，比如，屏幕组件100内包括第一部件101和第二部件102，且第一部件101和第二部件102的透光率均小于预设透光率，也就是说，第一部件101和第二部件102的透光率均较低，那么此时，就将第一部件101和第二部件102进行至少部分层叠设置，也就是说，将透光率较小的部件进行至少部分层叠，如此便可减小对第二光学信号的遮挡面积，从而使得更多的第二光学信号可以传输至光学传感器200，进而有助于提高光学传感器200采集指纹图像的清晰度，以提高光学指纹的识别精度。另一方面，屏幕组件100内设置有调节层300，调节层300的折射率大于氮气的折射率，由于通常情况下，调节层300的部位填充有氮气，以防止屏幕组件100内的器件被水气或者氧气腐蚀，影响使用寿命。当调节层300的折射率大于氮气的折射率时，可以使得屏幕组件100内各个层结构之间的折射率较为接近，即各个层结构的折射率的差值小于预设阈值，此时，可以减小第二光学信号在屏幕组件100内传播时的传输路径，使得第二光学信号近似直线传播，优化了第二光学信号的传输路径，减少了第二光学信号的损耗问题，有助于提高光学指纹的识别精度。
需要说明的是，第一、第二等词汇仅仅作为名称上的区分，既不是对数量的限定，也不是对顺序的限定。
所述屏幕组件100包括相对设置的第一表面100a和第二表面100b，所述光学传感器200位于所述第一表面100a的一侧，所述屏幕组件100用于朝向所述第二表面100b的一侧发射第一光学信号，所述第一光学信号在所述第二表面100b上反射后得到第二光学信号，所述光学传感器200接收所述第二光学信号并根据所述第二光学信号采集目标对象的指纹图像。
本申请实施例提供的显示屏组件10包括层叠设置的屏幕组件100和光学传感器200，通过屏幕组件100发射光学信号，光学传感器200接收光学信号以采集目标对象的指纹图像。将屏幕组件100内透光率小于预设透光率的部件进行至少部分层叠设置，从而减小对光学信号的遮挡，提高光学传感器200接收到的光学信号的量，进而提高指纹识别精度。或者，通过调节屏幕组件100内调节层300的折射率，使得调节层300的折射率大于预设折射率，其中，预设折射率为氮气的折射率，从而缩短光学信号的传输路径，减少光学信号的损耗，进而提高指纹识别精度。
请继续参阅图2，图2是本申请实施例提供的第二种显示屏组件的结构示意图。第二种显示屏组件的结构示意图与第一种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100包括层叠设置的基板110、薄膜晶体管层120、及发光单元130，所述基板110邻近所述光学传感器200设置，所述薄膜晶体管层120包括绝缘设置的第一金属层121、及第二金属层122，所述发光单元130包括第三金属层131，所述第一金属层121、所述第二金属层122、及所述第三金属层131在所述基板110上的投影中得至少两个部分重叠。
其中，所述基板110可以为刚性基板110，例如为玻璃基板110；所述基板110还可以为柔性基板 110，例如，所述柔性基板110由聚酰亚胺薄膜(PI)或聚酯薄膜与铜箔复合而成。由于聚酰亚胺耐高温锡焊、高强度、阻燃等优良性能，聚酰亚胺作为高分子材料具有突出的热稳定性，良好的耐辐射和化学稳定性和优良的力学性能。
具体的，第一金属层121包括栅极121a及电连接栅极121a的栅极线，第二金属层122包括源极122a、漏极122b，第三金属层131包括阳极层131a、第一传输线、及第二传输线，所述第一传输线用于传输第一信号，所述第二传输线用于传输第二信号，当所述第一信号被加载在所述发光单元130的阳极层131a且第二信号被加载在所述发光单元130的阴极层131b时，驱动发光单元130发光。其中，第一信号可以为高电平信号，也可以为低电平信号。第二信号可以为高电平信号，也可以为低电平信号。所述第一信号和所述第二信号之间形成电势差。
进一步的，第一金属层121、第二金属层122和第三金属层131在基板110上的投影至少两个部分重叠。在一种实施方式中，第一金属层121和第二金属层122在基板110上的投影至少部分重叠。当第一金属层121和第二金属层122之间具有重叠部分时，可以减少对第二光学信号的遮挡，使得更多的第二光学信号可以传输至光学传感器200上，有助于提高指纹识别精度。在另一种实施方式中，第一金属层121和第三金属层131在基板110上的投影至少部分重叠。当第一金属层121和第三金属层131之间具有重叠部分时，可以减少对第二光学信号的遮挡，使得更多的第二光学信号可以传输至光学传感器200上，有助于提高指纹识别精度。在又一种实施方式中，第二金属层122和第三金属层131在基板110上的投影至少部分重叠。当第二金属层122和第三金属层131之间具有重叠部分时，可以减少对第二光学信号的遮挡，使得更多的第二光学信号可以传输至光学传感器200上，有助于提高指纹识别精度。在又一种实施方式中，第一金属层121、第二金属层122和第三金属层131三者在基板110上的投影均至少部分重叠，当第一金属层121、第二金属层122和第三金属层131之间具有重叠部分时，可以减少对第二光学信号的遮挡，使得更多的第二光学信号可以传输至光学传感器200上，有助于提高指纹识别精度。
可以理解的，还可以通过减小第一金属层121、第二金属层122和第三金属层131的面积，即将栅极线、第一传输线及第二传输线设计的更细，使得栅极线、第一传输线及第二传输线的尺寸小于预设尺寸，从而可以减小栅极线、第一传输线及第二传输线对第二光学信号的遮挡，使得更多的第二光学信号可以传输至光学传感器200上，从而提高光学传感器200采集到指纹图像的清晰度，进而提高光学指纹的识别精度。
请继续参阅图3，图3是本申请实施例提供的第三种显示屏组件的结构示意图。第三种显示屏组件的结构示意图与第二种显示屏组件的结构示意图基本相同，不同之处在于，所述第一金属层121包括栅极121a，所述薄膜晶体管层120还包括有源层123及绝缘层124，所述有源层123、所述绝缘层124和所述栅极121a依次层叠设置，且所述有源层123邻近所述基板110设置。

所述阳极层131a设置在所述漏极122b的表面，且所述阳极层131a和所述漏极122b电连接。其中，所述阳极层131a和所述漏极122b电连接的方式可以为直接表面贴合的方式，也可以为电桥连接的方式。
请继续参阅图4，图4是本申请实施例提供的第四种显示屏组件的结构示意图。第四种显示屏组件的结构示意图与第二种显示屏组件的结构示意图基本相同，不同之处在于，所述第一金属层121包括栅极121a，所述薄膜晶体管层120还包括有源层123及绝缘层124，所述栅极121a、所述绝缘层124和所述有源层123依次层叠设置，且所述栅极121a邻近所述基板110设置。

请继续参阅图5，图5是本申请实施例提供的第五种显示屏组件的结构示意图。第五种显示屏组件的结构示意图与第二种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100还包括封装层140，所述发光单元130还包括发光层135、及阴极层131b，所述第三金属层131包括阳极层131a，所述发光层135夹设在所述阳极层131a及所述阴极层131b之间，所述阴极层131b与所述封装层140之间设置有防护层150，所述防护层150用于对所述发光层135形成防氧化保护。
其中，发光层135可以为有机发光层135。防护层150可以为干燥剂。所述防护层150用户防止阴极层131b、发光层135以及发光层135以下的功能器件被水气腐蚀。
所述封装层140为透明层，采用的是薄膜封装，用于对所述阴极层131b形成保护。因为阴极层131b及所述阴极层131b以下的各个膜层必须与外界隔离，以防止空气中的杂质对阴极层131b及所述阴极层131b以下的各个膜层的腐蚀而造成电气性能下降，保护阴极层131b及所述阴极层131b以下的各个膜层表面以及栅极线、第一传输线、第二传输线，使阴极层131b及所述阴极层131b以下的各个膜层在电气或热物理等方面免受外力损害及外部环境的影响；同时通过封装使阴极层131b及所述阴极层131b以下的各个膜层的热膨胀系数与框架或基板110的热膨胀系数相匹配，这样就能缓解由于热等外部环境的变化而产生的应力以及由于芯片发热而产生的应力，从而可防止阴极层131b及所述阴极层131b以下的各个膜层损坏失效。基于散热的要求，封装越薄越好。另一方面，封装后的阴极层131b及所述阴极层131b以下的各个膜层也更便于安装和运输。
进一步的，所述防护层150可以设置在所述封装层140邻近所述阴极层131b的表面，由于封装层140和阴极层131b之间通常会形成空腔，以便于填充惰性气体，惰性气体的作用是防止屏幕组件100内的器件被水气或者氧气腐蚀，影响使用寿命。
请继续参阅图6，图6是本申请实施例提供的第六种显示屏组件的结构示意图。第六种显示屏组件的结构示意图与第二种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100还包括缓冲泡棉400，所述缓冲泡棉400位于所述光学传感器200和所述基板110之间，所述缓冲泡棉400具有开口410，所述光学传感器200对应所述开口410设置。
具体的，所述缓冲泡棉400固定于所述基板110邻近所述光学传感器200的表面，所述缓冲泡棉400设置在所述基板110和所述光学传感器200之间，用于对所述基板110和所述光学传感器200形成缓冲 保护。所述缓冲泡棉400开设有开口410，所述开口410贯穿所述缓冲泡棉400，所述光学传感器200对应所述开口410设置。第二光学信号穿过所述开口410后可传输至所述光学传感器200，以被所述光学传感器200接收。
其中，所述开口410的形状可以为圆形，也可以为矩形，还可以为其他形式的形状。进一步的，在一种实施方式中，所述开口410的径向尺寸大于所述光学传感器200的镜头的径向尺寸。由于光学传感器200与基板110之间存在1-2毫米的间隙，而第二光学信号传输至光学传感器200形成的是一个锥形的区域。假如所述开口410的径向尺寸与所述光学传感器200的镜头的径向尺寸保持一致，那么，缓冲泡棉400上形成所述开口410的部分侧壁必然会对第二光学信号产生遮挡，对第二光学信号造成不必要的损失，因此，为了解决上述弊端，需要限定所述开口410的径向尺寸大于所述光学传感器200的镜头的径向尺寸，以便于使得更多的第二光学信号可以传输至光学传感器200，从而提高光学传感器200获取到的指纹图像的清晰度，进而提高光学指纹识别精度。
请继续参阅图7，图7是本申请实施例提供的第七种显示屏组件的结构示意图。第七种显示屏组件的结构示意图与第五种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100还包括触控层160、偏光片170、及盖板180，所述触控层160、所述偏光片170及所述盖板180依次设置在所述封装层140上，所述触控层160和所述偏光片170之间通过第一光学胶161连接，所述偏光片170和所述盖板180之间通过第二光学胶171连接。
其中，触控层160用于感应外部的触控动作，进而将触控动作转化为触控信号，将触控信号传输至控制器，以产生相应的控制指令，实现相应的触控功能。
在一些可能的实施方式中，屏幕组件100为封装完好的整体结构，触控层160与屏幕组件100层叠设置，即触控层160可以位于屏幕组件100的上面，也可以位于屏幕组件100的下面。当触控层160位于屏幕组件100的上面时，触控层160可以充当封装层140，即触控层160一方面可以对屏幕组件100起到保护的作用，另一方面，还可以用于检测屏幕组件100外部对所述屏幕组件100的触控动作，并用于根据触控动作产生触控信号。由于触控层160位于屏幕组件100的上面，当外部触控动作作用于屏幕组件100时，直接作用于触控层160上，外部触控动作无需经过其他层结构传递至触控层160，换句话说，此时的触控层160对于外部触控动作更为敏感，因此，可以在确保触控层160具有较高检测精度的前提下，减小触控层160的厚度，有助于实现显示屏组件10的轻薄化设计。
在另一些可能的实施方式中，触控层160内嵌于屏幕组件100内，即触控层160位于屏幕组件100任意相邻的两层结构之间，将触控层160内嵌于屏幕组件100，可以将触控层160和屏幕组件100作为一个整体一体化成型，有助于实现模块化设计，便于后续的安装以及拆卸更换等。且由于触控层160内嵌于屏幕组件100，可以使得触控层160更好的贴合于屏幕组件100。更进一步的，将触控层160附着于屏幕组件100内，可以有效的避免触控层160从屏幕组件100上脱落下来，从而可以延长显示屏组件10的使用寿命。
进一步的，在其他一些可能的实施方式中，触控层160可以为一个整体的层结构，可以与屏幕组件100保持同等大小，从而可以检测屏幕组件100的任意部位是否发生触控动作，以提高触控检测的精确度。
在另一些可能的实施方式中，触控层160也可以为间隔排布的若干个小的感应单元161组合而成， 此时，由于相邻的感应单元161之间为间隔排布，相邻的感应单元161之间不会产生相互的挤压作用，可以很好的消除相邻感应单元161之间的应力，进而将触控层160与屏幕组件100之间的应力释放，有助于避免出现应力集中的问题，假设有屏幕组件100和触控层160之间存在应力集中的情况，那么屏幕组件100和触控层160之间的内应力可能会对外部压力产生干扰，可能会导致触控检测不准确的情况，因此，通过将若干个感应单元161间隔排布形成触控层160，可以解决屏幕组件100和触控层160之间的应力集中问题，进而提高显示屏组件10检测外部触控动作的检测精度，进而提高显示屏组件10的触控灵敏度。
可选的，若干个感应单元161呈现阵列排布，以形成触控层160。当外部触控动作刚好施加于感应单元161时，通过感应单元161检测屏幕组件100外部对所述屏幕组件100的触控动作，并用于指示所述屏幕组件100发生触控的部位，以及所述屏幕组件100发生触控的轨迹。当外部触控动作施加于相邻两个感应单元161之间的部位时，通过相邻两个感应单元161检测到的触控动作对应的触控部位取平均值的方式来检测屏幕组件100外部对所述屏幕组件100的触控动作，并用于指示所述屏幕组件100发生触控的部位，以及所述屏幕组件100发生触控的轨迹。当外部触控动作同时作用于多个相邻的感应单元161时，根据外部触控动作的方向与感应单元161的中心部位之间的距离大小分配权重系数，根据分配至多个感应单元161上的权重系数计算屏幕组件100外部对所述屏幕组件100的触控动作对应的触控部位，并用于指示所述屏幕组件100发生触控的部位，以及所述屏幕组件100发生触控的轨迹。且具体的，外部触控动作对应的触控部位与感应单元161的中心部位之间的距离越小，分配的权重系数越大。
举例而言，假设外部触控动作同时作用于相邻的第一感应单元、第二感应单元和第三感应单元，外部触控动作对应的触控部位与第一感应单元之间的距离为d1，外部触控动作对应的触控部位与第二感应单元之间的距离d2，外部触控动作对应的触控部位与第三感应单元之间的距离d3，当d1<d2<d3时，分配至第一感应单元用于计算外部触控动作对应的触控部位的权重系数为a1，分配至第二感应单元用于计算外部触控动作对应的触控部位的权重系数为a2，分配至第三感应单元用于计算外部触控动作对应的触控部位的权重系数为a3，其中，a1>a2>a3，且a1+a2+a3＝1。
请继续参阅图8和图9，图8是本申请实施例提供的第八种显示屏组件的结构示意图。图9是本申请中显示屏组件的发光单元的驱动电路图。第八种显示屏组件的结构示意图与第一种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100还包括隔离柱500，所述屏幕组件100还包括驱动电路550、及发光单元130，所述驱动电路550用于驱动所述发光单元130工作，所述隔离柱500与所述驱动电路550中的存储电容551对应设置。
其中，所述驱动电路550包括存储电容551、及开关单元552，所述存储电容551与所述开关单元552相互配合以驱动所述发光单元130工作。
其中，隔离柱500的作用时防止屏幕组件100的发光层135在进行光罩蒸镀时，光罩与屏幕组件100已经做好的膜层发生刮伤。虽然隔离柱500材料透光率较高，但是还是会对光有一定的损耗，所以隔离柱500的位置应设计到本来透光率较低的区域，这样对透光率的损失最小。由于驱动电路550中的存储电容551的透光率较低，因此，在本实施例中，将隔离柱500与存储电容551对应设置，以减小隔离柱500以及存储电容551对透光率的不良干扰。将隔离柱500与存储电容551对应设置之后，整体透光率可提高0.91％。
进一步的，在一种实施方式中，所述隔离柱500对应所述存储电容551设置，且所述隔离柱500和所述存储电容551均避开所述发光单元130设置。相邻的发光单元130之间通过隔离层510形成隔离，以避免相邻的发光单元130发出的光线产生撞色，将隔离柱500和存储电容551对应所述隔离层510设置，以避免发光单元130，一方面，隔离柱500可以避免在制备发光单元130时，已经制备好的发光单元130被破坏的问题；另一方面，隔离柱500和存储电容551避开发光单元130，可以减小隔离柱500和存储电容551对发光单元130产生遮挡，导致显示屏组件10显示不良。
请继续参阅图10，图10是本申请实施例提供的第九种显示屏组件的结构示意图。第九种显示屏组件的结构示意图与第八种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100还包括封装层140，所述封装层140与所述发光单元130之间形成密封腔1000，密封腔1000内设置有惰性气体，所述调节层300包括所述密封腔1000及密封在所述密封腔1000内的惰性气体。
相关技术中，所述封装层140与所述发光单元130之间形成的密封腔1000内会填充氮气，目的是防止屏幕组件100内的器件被水气或者氧气腐蚀，影响使用寿命。在本实施例中，在所述封装层140与所述发光单元130之间形成的密封腔1000内会填充惰性气体，以减小屏幕组件100的各个层结构的折射率之间的差距，从而使得光线在屏幕组件100内的传输近似为直线，通过缩短光线的传输路径，进而减小光线的损失，使得更多的第二光学信号传输至光学传感器200，以提高光学传感器200采集到的指纹图像的清晰度，进而提高指纹识别精度。
所述调节层300可以认为是一个整体的封装结构，包括密封腔1000以及密封在所述密封腔1000内的惰性气体，有助于简化显示屏组件10的加工工艺。
请继续参阅图11，图11是本申请实施例提供的第十种显示屏组件的结构示意图。第十种显示屏组件的结构示意图与第九种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100还包括封装层140，所述发光单元130还包括阴极层131b，所述封装层140与所述阴极层131b之间形成所述密封腔1000，所述第二光学信号在所述惰性气体中传输的折射率为第一折射率，所述第二光学信号在所述阴极层131b中传输的折射率为第二折射率，所述第二光学信号在所述封装层140中传输的折射率为第三折射率，所述第二折射率与所述第一折射率之间的差值位于第一预设差值范围内，且所述第三折射率与所述第一折射率之间的差值位于第二预设差值范围内。
具体的，由于封装层140和阴极层131b形成所述密封腔1000，所述密封腔1000内密封有惰性气体。当第二光学信号在惰性气体内传输的第一折射率与第二光学信号在阴极层131b内传输的第二折射率之间的差值位于第一预设差值范围内，且第二光学信号在惰性气体内传输的第一折射率与第二光学信号在封装层140内传输的第三折射率之间的差值位于第二预设差值范围内时，可以使得第一折射率、第二折射率和第三折射率之间的差值较小，从而使得折射效果不明显，也就可以使得第二光学信号在屏幕组件100内的传输近似为直线传输，可以缩短第二光学信号的传输路径，从而可以减小第二光学信号产生的损耗，使得更多的第二光学信号传输至光学传感器200，进而使得光学传感器200采集到的指纹图像更加清晰，以便于提高光学指纹的识别精度。
请继续参阅图12，图12是本申请实施例提供的第十一种显示屏组件的结构示意图。第十一种显示屏组件的结构示意图与第一种显示屏组件的结构示意图基本相同，不同之处在于，所述调节层300内设置有有机层600，所述有机层600为光学透明层，所述第二光学信号在所述有机层600中传输的第四折 射率大于预设折射率，所述预设折射率为所述第二光学信号在氮气中传输的折射率。
具体的，当调节层300内设置有有机层600，且第二光学信号在有机层600内传输的第四折射率大于第二光学信号在氮气中传输的折射率，通过增大第二光学信号在调节层300内传输时的折射率，可以减弱折射效应，避免第二光学信号出现较大的折射偏转角，进而可以缩短第二光学信号的传输路径，使得第二光学信号的传输路径近似为直线型，减少第二光学信号产生损耗，可以使得更多的第二光学信号传输至光学传感器200，进而提高光学传感器200采集到的指纹图像的清晰度，进而提高显示屏组件10的指纹识别精度。
请继续参阅图13，图13是本申请实施例提供的第十二种显示屏组件的结构示意图。第十二种显示屏组件的结构示意图与第一种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100包括缓冲泡棉400和密封件650，所述缓冲泡棉400具有开口410，所述光学传感器200对应所述开口410设置，所述密封件650呈环形，且位于所述缓冲泡棉400和所述光学传感器200之间，所述密封件650在所述缓冲泡棉400与所述光学传感器200之间形成密封空间650a，所述密封空间650a内设置有透光部651，所述第二光学信号在所述透光部651内传输的第五折射率大于预设折射率，所述预设折射率为所述第二光学信号在氮气中传输的折射率。
具体的，由于第二光学信号在所述透光部651内传输的第五折射率大于第二光学信号在氮气中传输的折射率，从而可以避免第二光学信号由于折射作用产生较大的偏转角，可以使得第二光学信号朝向靠近光学传感器200的角度产生偏转，从而使得更多的第二光学信号可以传输至光学传感器200，进而使得光学传感器200采集到较为清晰的指纹图像，有助于提高光学指纹的识别精度。
进一步的，所述透光部651位于所述基板110邻近所述光学传感器200的表面，且所述透光部651远离所述基板110的表面朝向靠近基板110的一侧凹陷以形成凹陷面651a，所述凹陷面651a正对所述光学传感器200。所述透光部651为凹面结构，可以对第二光学信号起到汇聚的作用，使得更多的第二光学信号可以汇聚至光学传感器200上，以被光学传感器200接收，以提高光学传感器200采集到的指纹图像的清晰度，进而提高显示屏组件10的指纹识别精度。
请继续参阅图14，图14是本申请实施例提供的第十三种显示屏组件的结构示意图。第十三种显示屏组件的结构示意图与第一种显示屏组件的结构示意图基本相同，不同之处在于，所述屏幕组件100包括缓冲泡棉400和密封件650，所述缓冲泡棉400具有开口410，所述光学传感器200对应所述开口410设置，所述密封件650呈环形，且位于所述缓冲泡棉400和所述光学传感器200之间，所述密封件650的内壁上设置有反射涂层660，所述反射涂层660用于将所述第二光学信号反射至所述光学传感器200。
