技术领域
本申请涉及通信设备技术领域，尤其涉及一种电子设备。
背景技术
电子设备的显示屏是比较重要的人机交互部分，因此显示屏的结构将直接决定电子设备的用户体验是否良好。
电子设备中需要设置摄像头、指纹识别模组等光学器件，这些光学器件可以实现对应的拍摄、指纹识别等功能。以指纹识别为例，相关技术中大部分电子设备仅支持单点指纹识别，但随着消费者的需求不断升级，单点指纹识别的方式已经不能全面满足消费者的需求，多点指纹识别便应势而生。
为了实现多点指纹识别，电子设备需要对应不同的识别区域设置多个光学器件，导致电子设备内的空间被严重占用，造成电子设备的结构设计难度增大。
发明内容
本申请公开一种电子设备，以解决电子设备的结构设计难度较大的问题。
为了解决上述问题，第一方面，本申请提供了一种电子设备，包括：
显示屏；
光学器件，光学器件与显示屏相对设置，光学器件包括感光芯片，感光芯片具有至少两个感光区域，各感光区域均朝向显示屏；
导光件，导光件设置在显示屏与感光芯片之间，导光件的第一端朝向显示屏，导光件的第二端朝向至少一个感光区域。
本申请采用的技术方案能够达到以下有益效果：
本申请公开的电子设备设有导光件，感光芯片设有多个感光区域，显示屏的不同位置穿过的光线中，一部分可以直接到达至少一个感光区域，另一部分则可以通过导光件到达其他的感光区域。可见，该电子设备的感光芯片可以同时感应显示屏的不同位置所穿过的光线，因此光学器件的数量可以适当减少，从而缓解光学器件对电子设备内空间的占用，使得电子设备的结构设计更加简单。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各个实施例公开的技术方案。
如图1-图3所示，本申请实施例公开一种电子设备，其包括显示屏100、光学器件300和导光件400。
显示屏100用于显示。该显示屏100的数量可以为一个，也可以为两个，其中可以包括第一显示屏和第二显示屏，该第一显示屏和第二显示屏可以相背设置，也就是说，第一显示屏和第二显示屏设置于电子设备的背对两侧，使得电子设备成为双面屏结构。具体地，第一显示屏可以是正面屏，第二显示屏可以是背面屏。
如图2所示，光学器件300与显示屏100相对设置，该光学器件300包括感光芯片310，该感光芯片310具有至少两个感光区域，各感光区域均朝向显示屏100。需要说明的是，当显示屏包括第一显示屏和第二显示屏时，各感光区域均朝向同一个第一显示屏或同一个第二显示屏。具体地，如图3所示，这些感光区域可以包括第一感光区域311和第二感光区域312。感光芯片310的形状可以是矩形、圆形、椭圆形等，感光区域的形状可以是矩形、圆形、椭圆形等，本申请实施例对此不做限制。感光区域可以用于感光，从而可以将光信号转换为电信号，以便于实现该光学器件300的光学功能。
可选地，感光芯片310可以通过柔性电路板与电子设备的主板电连接，从而便于感光芯片310和主板之间进行电信号的传递。
如图2所示，导光件400设置于显示屏100与感光芯片310之间，导光件400的第一端朝向显示屏100，导光件400的第二端朝向至少一个感光区域。这里的导光件400可以实现导光作用，具体地，进入导光件400的第一端的光线可以在导光件400内传播，并最终通过导光件400的第二端射出。
上述感光芯片310设有多个感光区域，同一个显示屏100的不同位置穿过的光线中，一部分可以直接到达至少一个感光区域，另一部分则可以通过导光件400到达其他的感光区域，如图2所示。可见，该电子设备的感光芯片310可以同时感应显示屏100的不同位置所穿过的光线，因此光学器件300的数量可以适当减少，从而缓解光学器件300对电子设备内空间的占用，使得电子设备的结构设计更加简单。
可选地，上述导光件400可以选用棱镜，该棱镜可以利用全反射原理实现光线的反射，因此该棱镜具有较好的导光效果，从而使得更多的光线可以通过导光件400到达感光区域，以改善感光芯片310的感光效果。
在一种可选的实施例中，光学器件300可以是指纹识别模组，此时，如图1所示，显示屏100具有多个识别区域，该多个识别区域可以包括第一识别区域110和第二识别区域120，如前所述，多个感光区域可以包括第一感光区域311和第二感光区域312，第一感光区域311与第一识别区域110相对，导光件400的第一端朝向第二识别区域120，第二端朝向第二感光区域312。参考图2中箭头线所示的光路方向，当用户的手指500放在第一识别区域110时，穿过显示屏100的光线到达用户的手指500后，由于手指500的指纹具有指纹谷和指纹脊，因此光线可以被不同程度地反射，使得被反射的光线携带用户的指纹信息，这些光线到达感光芯片310的第 一感光区域311后，感光芯片310可以将光信号转换成电信号，并进行运算处理，最终得到用户的指纹信息，该指纹信息可以与电子设备内预存的指纹信息进行对比，从而判断用户的访问是否合法。同理地，当用户的手指500放在第二识别区域120时，穿过显示屏100的光线到达用户的手指500后被反射，被反射的光线携带用户的指纹信息，这些光线通过导光件400到达感光芯片310的第二感光区域312后，感光芯片310可以将光信号转换成电信号，并进行运算处理，最终得到用户的指纹信息，该指纹信息可以与电子设备内预存的指纹信息进行对比，从而判断用户的访问是否合法。采用此方案后，无论用户操作显示屏100的哪个位置，均可以实现指纹识别，使得电子设备的指纹识别操作更加方便。
上述导光件400的结构可以灵活选择，为了简化导光件400的结构，同时减小导光件400所占用的空间，可以将导光件400设置为条形结构，导光件400的延伸方向平行于显示屏100。此时，导光件400在电子设备的厚度方向上所占用的空间可以进一步减小，从而更有利于电子设备内其他零部件的堆叠。与此同时，电子设备在平行于显示屏100的方向上的空间相对比较充裕，因此导光件400的尺寸可以适当增大，以使得该导光件400可以实现更多位置处的指纹识别，以进一步方便电子设备的指纹识别操作。
可选地，如图2所示，导光件400可以设置第一反射面410和第二反射面420，该第一反射面410具体可以设置于导光件400的第一端，第二反射面420具体可以设置于导光件400的第二端，第一反射面410朝向第二识别区域120，第二反射面420朝向第二感光区域312。此时，第二识别区域120处经手指500反射的光线进入导光件400以后，经第一反射面410反射至第二反射面420，第二反射面420进一步将这些光线反射至第二感光区域312，以便于感光芯片310实施指纹识别操作。第一反射面410和第二反射面420均可以相对于显示屏100倾斜设置，从而实现光线的反射。 采用此种技术方案时，光线可以经过至少两次反射再到达感光芯片310，无论第二识别区域120与第二感光区域312之间的距离较远或是较近，都可以准确地使光线到达第二感光区域312，因此该结构可以更好地适应用户在显示屏100的多个位置实施指纹识别操作的需求。
进一步地，第一反射面410和第二反射面420均可以设置为平面，且两者相互平行。此时，导光件400的结构更加简单，且光线在导光件400内的传播方向更加可控，从而更便于感光芯片310等部件的设置。更进一步地，第一反射面410与显示屏100之间的夹角可以为45°，第二反射面420与显示屏100之间的夹角也可以为45°，此时感光芯片310所在的平面可以平行于显示屏100，而电子设备在平行于显示屏100的方向上可供设置感光芯片310的空间更加充足，使得感光芯片310的尺寸可以适当增大，以此改善感光芯片310的感光效果，从而优化光学器件300的工作性能。
在另一种实施例中，光学器件300可以是摄像头，此时，显示屏100具有多个透光区域，这些透光区域可以包括第一透光区域和第二透光区域，如前所述，多个感光区域可以包括第一感光区域311和第二感光区域312，第一感光区域311与第一透光区域相对，导光件400的第一端朝向第二透光区域，导光件400的第二端朝向第二感光区域312。这里的第一透光区域和第二透光区域均可以供光线穿过，因此外部环境中的光线可以通过第一透光区域进入感光芯片310的第一感光区域311，从而实现第一透光区域周围的拍摄操作；外部环境中的光线通过第二透光区域后，可以通过导光件400到达感光芯片310的第二感光区域312，从而实现第二透光区域周围的拍摄操作。采用此方案后，用户可以更加方便地实现不同位置处的拍摄操作，使得电子设备的拍摄操作更加方便。
当然，光学器件300除了可以是上文所述的指纹识别模组和摄像头以 外，还可以是其他器件，例如可以是红外补光灯等。
在进一步的实施例中，光学器件300还可以包括配光元件320，该配光元件320设置于显示屏100和感光芯片310之间。可选地，该配光元件320可以包括透镜、准直器以及滤光片中的至少一者，当然，该配光元件320还可以包括其他具有配光作用的元件，本文对此不做限制。配光元件320可以改变光线的传播方向，从而实现光线的聚拢、过滤等作用，以此使得到达感光芯片310的光线更有利于该感光芯片310的感光。具体实施例中，配光元件320的数量可以为一个，也可以为多个，具体可以根据配光需求灵活选择。
考虑到经过导光件400导向的光线的传播方向具有一定的不确定性，因此为了改善第二感光区域312的感光效果，可以使配光元件320的一部分位于导光件400的第二端和感光芯片310之间，从而使得配光元件320可以进一步改变自导光件400射出的光线的传播方向，从而使得第二感光区域312更准确、更高效地感应经导光件400导向的光线。此时，配光元件320的另一部分可以位于显示屏100和第一感光区域311之间，从而使得配光元件320还可以对经过显示屏100另一位置的光线进行配光，以此强化配光元件320的配光效果。
本申请实施例中，显示屏100可以采用液晶显示屏，也可以采用有机发光显示屏。当显示屏100采用有机发光显示屏时，该显示屏100可以包括第一基板101、第二基板102和有机发光层103，该有机发光层103设置于第一基板101和第二基板102之间，该有机发光层103可以包括多个显示像素103a，这些显示像素103a可以受程序控制而发光。第一基板101、第二基板102均可以采用玻璃板，两者可以保护有机发光层103，同时还可以作为显示屏100的其他组成部分的设置基础。相对而言，有机发光显示屏的显示效果更优，并且，有机发光层103的显示像素103a之间的间隙 可供光线穿过，从而便于将光学器件300布置在显示屏100的下方，以此提升电子设备的屏占比。进一步地，显示屏100可以为主动矩阵有机发光二极体(Active Matrix Organic Light Emitting Diode，AMOLED)显示屏。
可选地，感光芯片310的各感光区域可以分体设置，但是为了便于加工该感光芯片310，同时在形成同等的感光面积的情况下尽量减小感光芯片310的尺寸，可以使各感光区域共同形成一体式感光区域。即，各感光区域直接接触，其所对应的部分可以一体成型。此时，感光芯片310还具有走线区域313，该走线区域313可以设置感光芯片310的走线结构，其可以位于整个感光芯片310的边缘处，且该走线区域313环绕该一体式感光区域。
本申请实施例所公开的电子设备可以为智能手机、平板电脑、电子书阅读器或可穿戴设备。当然，该电子设备也可以是其他设备，本申请实施例对此不做限制。
本申请上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
