附图说明
为了更清楚地说明本申请实施例的技术方案，下面将对本申请实施例描述中所需要使用的附图作简单地介绍。
图1本申请实施例提供的感光模组的示意图；
图2是申请另一实施例提供的感光模组的示意图；
图3是申请另一实施例提供的感光模组的示意图；
图4是申请另一实施例提供的感光模组的示意图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，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的前提下所获得的所有其它实施例，都属于本申请保护的范围。
请参看图1所示的本申请电子设备100，设置于可透光显示面板30远离出光面31的一侧。显示面板30内通常包括第一偏光片41，第一偏光片41可用于消除环境光在显示面板30内的光线反射，并对射入的环境光进行偏振过滤。显示面板30包括出光面31和与出光面31相对的背面32。第一偏光片41设置于出光面31一侧。电子设备100还包括感光模组200，感光模组200包括有第一光传感器10、第二光传感器20以及第二偏光片42。第一光传感器10设置于显示面板30远离出光面31一侧，也即第一光传感器10设置于显示面板30的背面32一侧。环境光从外界穿过第一偏光片41射入显示面板30后，部分被显示面板30反射。被反射的光线会因为第一偏光片41的作用而不能从显示面板30再向外发出，达到第一偏光片41消除光线反射的目的。而另 一部分光线会穿过显示面板30从背面32射出。第一光传感器10用于接收该部分光线，此为环境光在本申请感光模组200中朝向第一光传感器10传播的光路。进一步的，第一光传感器10还用于接收显示面板30自身产生的光。可以理解的，电子设备100会通过显示面板30向用户显示图像。显示面板30自身会发光。而显示面板30发出的光也会从背面32射出，到达第一光传感器10的位置。因此，在本申请感光模组200中，第一光传感器10会同时检测到环境光以及显示面板30发出的光。
第二光传感器20设置于第一光传感器10的一侧，二者相邻设置。在第二光传感器20和显示面板30之间还设有第二偏光片42。即从背面32射出的光线需要先通过第二偏光片42再到达第二光传感器20。与第一光传感器10不同的是，外界环境光在穿过第一偏光片41之后，会根据光线的偏振方向对环境光进行过滤，即只允许朝向第一方向偏振的光线通过。在经过第二偏光片42时，会再次根据光线的偏振方向对第一偏光片41透射进来的光进行过滤，只允许朝向第二方向偏振的光线通过。即通过对第一方向和第二方向的配合，能使得大部分环境光被第一偏光片41和第二偏光片42阻隔。通常的，第一偏光片41的光轴与第二偏光片42的光轴会形成夹角，以阻隔环境光线连续通过第一偏光片41和第二偏光片42。理论上，该夹角被设置为90度效果最佳，即第一偏光片41的光轴与第二偏光片42的光轴相互垂直时，不会有外界环境光穿过第二偏光片42到达第二光传感器20。而显示面板30自身产生的光则可以穿过第二偏光片42直接到达第二光传感器20。即通过第二偏光片42与第一偏光片41的配合，可以使得第二光传感器20只接收到显示面板30产生的光。
因为第一光传感器10和第二光传感器20相邻排列设置，当二者距离很近时，第一光传感器10和第二光传感器20接收到显示面板30产生的光近乎一致。因此，造成第一光传感器10感应到的光线强度和第二光传感器20感应到的光线强度的差异，来自于第一光传感器10还可以接收到环境光。由此，通过计算第一光传感器10与第二光传感器20在同一时刻接收到的光线差值，可以推算出当前的环境光大小，进而以辨认电子设备100当前所处的环境和场景。进一步的，电子设备100根据当前的环境光强度，可以自动调整显示面板 30的显示亮度，提升用户的使用体验。感光模组200还可以基于环境光强度进行探距，在用户使用电子设备100接听电话时实现自动熄屏。本申请感光模组200因为第一光传感器10和第二光传感器20的设置以及配合工作，使得显示面板30在不开孔的情况下也能感应到环境光，取代了现有的在显示面板30上开孔的结构，从而保证了电子设备100的外观一致性，加大了电子设备100实现全面屏的可能性，提升了用户体验。
需要提出的是，本申请方案并不对环境光的波段做严格限制。即本申请方案可以通过第一光传感器10和第二光传感器20同时感应可见光，也可以通过第一光传感器10和第二光传感器20同时感应红外光。可以理解的，只要第一光传感器10和第二光传感器20所感应的光波段一致，都可以通过二者的配合比对来得到光强度的差异，并基于该差异来辨认外界环境光的强度。而当前的偏光片、光传感器等产品，都可以达到同时覆盖300～1100nm波长光线的功能，因此本申请感光模组200可以只用于监测可见光或红外光，也可以同时对可见光和红外光进行监测，只要第一光传感器10和第二光传感器20在同一监测时刻的光线波长一致，都可以达到感应环境光强度的功能。
另一方面，显示面板30的类型，需要可以穿透环境光，以实现环境光射入第一光传感器10的功能。在当前的主流显示技术中，oled面板可以达到相应的效果。当然本申请电子模组100也不局限于采用oled技术的显示面板，对于今后可能出现的Qled面板、或其它显示技术的面板，只要能实现环境光的穿透功能，都可以用作本申请电子设备100的显示面板，并达到与oled面板类似的效果。进一步的，因为显示面板30在出光面31的任意位置都可以穿透环境光，因此在本申请电子设备100中，第一光传感器10和第二光传感器20可以设置在相对于出光面31的任意位置处。因为不需要在显示面板30上打孔，因此第一光传感器10和第二光传感器20设置在任意位置都不会影响显示面板30的显示效果。
请继续参见图1，为了实现第一光传感器10和第二光传感器20在电子设备100中的定位，感光模组200还设置有支架50。支架50内形成有第一收容空间51和第二收容空间52。其中第一收容空间51和第二收容空间52均朝向显示面板30开口，用于光线的射入。第一收容空间51和第二收容空间52之 间还设置有分隔结构53。第一光传感器10固定设置于第一收容空间51内，第二光传感器52固定设置于第二收容空间52内。环境光和显示面板30产生的光分别进入第一收容空间51和第二收容空间52以被第一光传感器10和第二光传感器20分别接收。其中分隔结构53还用于隔离第一收容空间51和第二收容空间52内的光线，避免第一收容空间51与第二收容空间52之间产生漏光，影响第一光传感器10和第二光传感器20的感光精度。
一种实施例，因为第二偏光片42为膜状或片状结构，其结构强度不高，因此在支架50朝向显示面板30一侧还设置了透光盖板60。第二偏光片42贴附并固定于透光盖板60上，以使得第二偏光片42能稳定的被支撑在感光模组200中，并对第二光传感器20过滤环境光。需要提出的是，透光盖板60需要具备较高的光透过率，避免环境光和显示面板30产生的光在穿过透光盖板60的过程中受到损失以影响第一光传感器10和第二光传感器20的感光精度。另一方面，透光盖板60可以只覆盖于第二收容空间52处，也可以同时覆盖第一收容空间51和第二收容空间52。透光盖板60始终会造成一定的光强度损耗，当透光盖板60同时覆盖第一收容空间51和第二收容空间52时，透光盖板60对光强度的影响会同时传递给第一光传感器10和第二光传感器20，消除因透光盖板60而造成的第一光传感器10和第二光传感器20之间的光强度差异。
一种实施例请参见图2，第一光传感器10与第二光传感器20沿第一方向001排列，第一光传感器10和第二光传感器20均倾斜于显示面板30，第一光传感器10与第二光传感器20的感光面均沿相互靠近的方向朝向显示面板30倾斜，也即第一光传感器10沿第一方向001朝第二光传感器20倾斜，第二光传感器20也沿第一方向001朝第一光传感器10倾斜。二者相向倾斜的角度与二者的可视角度以及与显示面板30的距离相关联，以使得第一光传感器10与第二光传感器20均朝向显示面板30的同一显示区域接收显示面板30产生的光。前述中提到，因为第一光传感器10和第二光传感器20相邻排列设置，当二者距离很近时，第一光传感器10和第二光传感器20接收到显示面板30产生的光近乎一致。但随着显示面板的分辨率越来越高，即使相邻很近的显示区域也可能因为画面不同而导致其显示面板30发出的光强度出现差异。而将第一光传感器10和第二光传感器20通过相向倾斜而使二者均朝向同一显示区 域接收显示面板30产生的光，可以消除因为显示画面不同而造成的入光量的差异，进而提高对环境光感测的精度。
另一种实施例，第一光传感器10和第二光传感器20沿第一方向001平行排列，第一光传感器10正对显示面板30的第一区域301以采集第一区域301产生的光，第二光传感器20正对显示面板30的第二区域302以采集第二区域302产生的光。感光模组200还用于实时计算第一区域301与第二区域302的画面亮度差异值，并将该差异值代入环境光检测的对比值中作为对环境光强度的修正。通过计算所述第一区域与所述第二区域的画面亮度差异值来修正计算得到的环境光大小，同样可以提高所述感光模组200的环境光检测精度。
请参见图3的实施例，第一光传感器10正对显示面板30的第一区域301以采集第一区域301产生的光。第一光传感器10与显示面板30之间还设有分光器70。分光器70包括分光面701。光线达到分光面701后会分为偏振方向相互垂直的两组偏振光，且两组偏振光的光强度均分。一组偏振光从分光器70直接透射给第一光传感器10，另一组偏振光沿第一方向001穿过第二偏关片41后投射给第二光传感器20。分光器70为光学设计中常用的光学元件，其均匀分光的特性适用于本申请感光模组200的环境光感测方案。因为第一光传感器10和第二光传感器20均接收从第一区域301处射入的环境光，以及第一区域301产生的光。在分光器70对光线进行均分后，朝向第一光传感器10透射的光线强度与朝向第二光传感器20投射的光线强度相同。而朝向第二光传感器20投射的光线在经过第二偏光片42之后，其环境光被第二偏光片42阻隔。由此，第一光传感器10接收到的光强度为环境光与第一区域301产生光，第二光传感器20接收到的光强度为第一区域301产生的光。通过二者的对比，依然可以解算出环境光的强度。同时，利用分光器70将第一区域301产生的光均匀的分给第一光传感器10和第二光传感器20，也是消除显示画面亮度差异的一种方式。
在图3的实施例中，第一光传感10器朝向显示面板30设置，第二光传感器20垂直于第一光传感器10设置，以使得第二光传感器20朝向分光器70并接收由分光器70反射出的第二组偏振光。第二偏光片42设置于第二光传感器20与分光器70之间。第二光传感器20垂直于第一光传感器10设置，可以 配合分光器70的光路，正对分光器70以接收第一区域301的一组偏振光。
在图4的实施例中，感光模组200还设置了反光板80。反光板80用于将分光器70朝向第二光传感器20投射的一组偏振光进行反射，以使得该组偏振光垂直投射到第二光传感器20上。由此，第一光传感器10与第二光传感器20均得以朝向显示面板30设置，避免第二光传感器20垂直于第一光传感器10设置时增加电子设备100的厚度。利用反光板80来改变投射至第二光传感器20的光线的光路，使得第一光传感器10与第二光传感器20均朝向显示面板30设置，有利于控制电子设备100的厚度，实现电子设备100的轻薄化设计。
本申请还涉及一种显示装置(图中未示)。显示装置包括有上述可透光的显示面板30，以及上述的感光模组200。可以理解的，与本申请涉及的电子设备100类似，显示装置在包括显示面板30和感光模组200之后，也避免了在显示面板30上开孔来进行光线感测的情况，保证了显示装置的外观一致性，可作为具备感光功能的全面屏显示装置应用于各种电子产品中，提升用户体验。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
