背景技术
指纹模组、摄像头等光学器件是电子设备的核心部件之一，随着电子设备行业的不断发展，人们对于这些光学器件的性能要求越来越高，这就给电子设备的结构设计带来比较大的挑战。
以指纹模组为例，指纹模组的结构形式比较多样，能够设置于显示屏下方的光学指纹模组可以提升电子设备的外观质感，因此此种指纹模组得到了越来越广泛的应用。具体地，显示屏上设有指纹识别区域，用户可以将手指放置在该指纹识别区域，该指纹识别区域下方的指纹模组即可识别用户的指纹信息。
但是，进行指纹解锁时，显示屏的指纹识别区域的亮度会高于其他区域的亮度，导致指纹识别区域的温度相对会高于其他区域的温度，从而加速指纹识别区域的发光材料的老化。同时，随着使用时间的延长，指纹识别区域的发光时间要多于其他区域的发光时间，导致指纹识别区域的发光材料以更高的速度老化。因此，显示屏进行显示时，指纹识别区域容易出现残影等问题，使其显示效果比其他区域的显示效果差，导致显示屏的显示效果变差。

其中，所述驱动电压与所述显示参数正相关或者负相关。
第四方面，本发明公开一种电子设备，包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现上述方法的步骤。
第五方面，本发明公开一种计算机可读存储介质，所述计算机可读存储 介质上存储计算机程序，所述计算机程序被处理器执行时实现上述方法的步骤。

为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
如图1-图3所示，本发明实施例公开一种电子设备，其包括显示屏100、光学器件和驱动芯片200。显示屏100具有第一区域101和第二区域102，第一区域101和第二区域102均可以是显示屏100的显示区域，第二区域102可以位于第一区域101之外。光学器件与第一区域101相对设置，即，在垂直于显示屏100的方向上，光学器件的至少部分投影与第一区域101的投影相重合，该第一区域101可供光线穿过，从而使得光学器件可以正常工作。可选地，第二区域102可以环绕第一区域101，第一区域101可以是圆形区域、矩形区域或者也可以设置为其他形状的区域。驱动芯片200可以实现显示屏100的驱动。
请参考图3，一种可选的实施例中，显示屏100可以是有机发光显示屏，例如该显示屏100可以是有源矩阵有机发光二极体(Active-Matrix Organic Light-Emitting Diode，AMOLED)显示屏。具体地，该显示屏100可以包括第一基板、第二基板和有机发光层120。第一基板和第二基板均可以采用玻璃基板或者聚酰亚胺(Polyimide，PI)基板，当然也可以采用其他材质的基板。第一基板朝向第二基板的一侧可以设置薄膜晶体管和阳极层110，有机发光层120可以设置于第一基板和第二基板之间，有机发光层120和第二基板之间设有阴极层130，在薄膜晶体管的驱动作用下，该阴极层130与阳极层110之间可以形成电场，从而驱动有机发光层120发光。具体地，有机发光层120可以包括空穴注入层121、空穴传输层122、发光层123、电子传输层124和电子注入层125。
另一种实施例中，上述显示屏100还可以是液晶显示屏100，该液晶显示屏100具体可以包括第一基板、第二基板和液晶层，该液晶层设置于第一基板和第二基板之间，第一基板和第二基板之间同样设置有阳极层110和阴极层130，具体地，阴极层130设置于第二基板朝向液晶层的一侧。该阳极层110和阴极层130所形成的电场施加在液晶层上以后，液晶层的状态将发生变化。与此同时，该显示屏100设有背光源，液晶层的状态发生变化以后，可以调整背光源所发出光线的状态，从而达到显示目的。
当然，显示屏100还可以采用其他结构，本发明实施例不做限定。
如前所述，显示屏100包括阴极层130，该阴极层130具体可以包括第一子阴极层131和第二子阴极层132，该第一子阴极层131和第二子阴极层132同层设置且彼此绝缘。第一子阴极层131和第二子阴极层132分别与驱动芯片200电连接，第一子阴极层131和光学器件在垂直于显示屏100的方向上排布，也就是说，第一子阴极层131对应第一区域101设置。此种结构中，第一子阴极层131和第二子阴极层132可以共同与阳极层110作用，从而形成驱动所需的电场，同时第一子阴极层131和第二子阴极层132的控制可以独立进行。
当显示屏100包括有机发光层120时，上述第一子阴极层131和第二子阴极层132位于该有机发光层120的同一侧。当显示屏100包括液晶层时，上述第一子阴极层131和第二子阴极层132位于该液晶层的同一侧。
由于第一区域101和第二区域102的工作频率、工作时长等可能不同，因此显示屏100中位于第一区域101和第二区域102的部分的老化程度不同，因此这两部分结构的显示效果就会出现差异，该显示效果具体可以通过显示参数来衡量。可选地，该显示参数具体可以包括亮度，当然也可以包括其他可以用于衡量显示效果的参数。而采用上述结构后，当显示屏100的第一区域101和第二区域102的同一显示参数出现差异，即该显示参数的数值不同时，则可以分别控制第一子阴极层131和第二子阴极层132的驱动电压，该驱动电压与显示参数正相关或者负相关，也就是说，增大驱动电压可以增大显示参数的数值，减小驱动电压可以减小显示参数的数值；或者，增大驱动电压可以减小显示参数的数值，减小驱动电压可以增大显示参数的数值。所以，分别控制第一子阴极层131和第二子阴极层132的驱动电压后，可以使得第一区域101的显示参数和第二区域102的显示参数趋于一致，进而改善显示屏100的显示效果。
上述第一子阴极层131和第二子阴极层132之间可以存在间隙，从而使得两者可以彼此绝缘。但是此种结构容易导致阴极层130的结构强度较差，同时第一子阴极层131和第二子阴极层132也可能出现绝缘失效的问题。为此，进一步地，阴极层130还可以包括绝缘部133，该绝缘部133与第一子阴极层131和第二子阴极层132同层设置，且绝缘部133位于第一子阴极层131 和第二子阴极层132之间。这里的绝缘部133可以填充第一子阴极层131和第二子阴极层132之间的间隔，从而提升阴极层130的结构强度，同时改善第一子阴极层131和第二子阴极层132之间的绝缘可靠性，以此更可靠地单独控制第一子阴极层131和第二子阴极层132的驱动电压。
一种可选的实施例中，光学器件可以为指纹模组，前文所述的第一区域101为指纹识别区域。当用户将手指放在指纹识别区域上以后，显示屏100发出的光线可以被用户的手指反射，反射的光线可以携带用户的指纹信息，这些光线穿过指纹识别区域后到达指纹模组，使得指纹模组可以获取用户的指纹信息，从而判断用户的访问是否合法。当电子设备不需要进行指纹识别时，则可以单独控制第一子阴极层131和第二子阴极层132的驱动电压，从而使得显示屏100进行显示时可以达到一致的显示效果。
另一种可选的实施例中，光学器件还可以为摄像头，前文所述的第一区域101为透光区域。外部环境中的光线可以穿过透光区域，并射入摄像头内，使得摄像头可以完成成像操作。同理地，当电子设备不需要拍摄时，则可以单独控制第一子阴极层131和第二子阴极层132的驱动电压，从而使得显示屏100进行显示时可以达到一致的显示效果。
当然，光学器件还可以是其他器件，例如可以是补光灯、传感器等器件，本发明实施例对此不做限制。
基于本发明实施例公开的上述电子设备，本发明实施例还公开一种电子设备的控制方法，该控制方法可以包括：
S100、获取显示信号；
这里的显示信号指的是显示屏100需要进行显示的信号，例如当光学器件为指纹模组时，电子设备不需要进行指纹识别，且显示屏100需要被点亮时，电子设备即收到显示信号，此时显示屏100的第一区域101和第二区域102均需要显示对应的内容。
S200、根据上述显示信号，确定第一区域101和第二区域102的显示参数；
当显示屏100被整体点亮时，可以确定第一区域101和第二区域102的显示参数，从而判断第一区域101和第二区域102的显示效果是否一致。可 选的实施例中，该显示参数可以包括亮度，当电子设备获取到显示信号时，根据该显示信号，可以确定第一区域101和第二区域102的亮度是否相等。如果相等，则表明第一区域101和第二区域102的显示效果一致，否则，第一区域101和第二区域102的显示效果存在差异。
S300、当第一区域101的显示参数与第二区域102的显示参数的数值不同时，改变第一子阴极层131和第二子阴极层132中的至少一者的驱动电压，直至第一区域101的显示参数的数值等于第二区域102的显示参数的数值；其中，该驱动电压与显示参数正相关或者负相关。
当第一区域101的显示参数与第二区域102的显示参数的数值相等时，第一子阴极层131和第二子阴极层132的驱动电压可以不进行调整；当第一区域101的显示参数与第二区域102的显示参数的数值不同时，第一区域101和第二区域102的显示效果不同，导致用户体验下降。因此，可以改变第一子阴极层131和第二子阴极层132中的至少一者的驱动电压，使得第一区域101和第二区域102的显示效果趋于一致，从而改善用户体验。具体地，可以单独调整第一子阴极层131或者第二子阴极层132的驱动电压，也可以同时调整第一子阴极层131和第二子阴极层132的驱动电压，从而使得第一区域101和第二区域102的显示效果趋于一致。
需要说明的是，上文中的“相等”、“等于”均非绝对的相等和等于，可以有轻微的浮动范围。
本发明实施例还公开一种电子设备，该电子设备可以应用上述任一实施例所述的控制方法，其可以包括获取模块、处理模块和控制模块。其中：获取模块用于获取显示信号；处理模块用于根据该显示信号，确定第一区域101和第二区域102的显示参数；控制模块用于在第一区域101的显示参数与第二区域102的显示参数的数值不同时，改变第一子阴极层131和第二子阴极层132中的至少一者的驱动电压，直至第一区域101的显示参数的数值等于第二区域102的显示参数的数值，从而使得第一区域101和第二区域102的显示效果趋于一致，以此改善显示屏100的整体显示效果。其中，这里的驱动电压与显示参数正相关或者负相关。
本发明实施例还公开一种电子设备，其包括处理器、存储器及存储在存 储器上并可在处理器上运行的计算机程序，计算机程序被处理器执行时实现上述任一实施例所述的方法的步骤。
本发明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，本发明实施例对此不做限制。
本发明实施例还公开一种计算机可读存储介质，计算机可读存储介质上存储计算机程序，计算机程序被处理器执行时实现上述任一实施例所述的方法的步骤。
本发明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。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
