下面以移动电话为例结合附图对本发明实施例作进一步阐述。
图1a,图1b,图1c，图1d是本发明实施例提供的一种电子设备的结构示意图， 其中，图1a为电子设备的框架结构示意图,图1b为电子设备的外形结构正面示意图，图1c为电子设备的外形结构背面示意图，图1d为电子设备的外形结构翻转状态示意图。为了便于说明，仅列出与本发明实施例相关的部分。如图1a所示为电子设备的框架结构示意图，该电子设备100包括：显示驱动模组110、第一显示屏120和第二显示屏130；第一显示屏120位于电子设备100的正面，如图1b所示；第二显示屏130位于电子设备100的背面，如图1c所示；电子设备100的第二显示屏130可以沿着第一显示屏120和第二显示屏130之间的转轴在0-180度范围内翻转，呈现出电子设备100的翻转状态，如图1d所示。显示驱动模组110包括第一驱动单元111和第二驱动单元112；第一驱动单元111用于驱动第一显示屏120，第二驱动单元112用于驱动第二显示屏130，并且第二驱动单元112基于第一驱动单元111发送的通知消息控制第二显示屏130。
在本发明实施例中，第一驱动单元111在确定电子设备100在准备执行具体功能过程中，比如，通话或者拍照时，确定电子设备靠近人脸或电子设备前方存在拍摄对象时，可以向第二驱动单元112发送通知消息，以使第二驱动单元112基于该通知消息控制第二显示屏130，其中，控制第二显示屏130可以包括控制第二显示屏130显示的内容，或者控制第二显示屏130是否响应具体操作，比如，控制第二显示屏130显示预设图像，或者控制第二显示屏130不响应触控操作。
在本发明实施例中，电子设备通过第一驱动单元驱动第一显示屏，第二驱动单元驱动第二显示屏，并且第二驱动单元基于第一驱动单元发送的通知消息控制第二显示屏，以使不同显示屏之间通过驱动单元实现关联控制，提升了用户体验。
图2是本发明实施例提供的另一种电子设备的结构示意图。为了便于说明，仅列出与本发明实施例相关的部分。如图2所示，该电子设备200包括：显示驱动模组210、第一显示屏220和第二显示屏230；第一显示屏220位于电子设备200的正面，第二显示屏230位于电子设备200的背面；显示驱动模组210包括第一驱动单元211和第二驱动单元212；第一驱动单元211用于驱动第一显示屏220，第二驱动单元212用于驱动第二显示屏230，并且第二驱动单元212基于第一驱动单元211发送的通知消息控制第二显示屏230。
在本发明实施例中，电子设备200还包括通话模组240，通话模组240用于 与远端进行通话。第一显示屏220包括显示模组221和感应装置222；其中，显示模组221用于显示内容，感应装置222用于确定用户人脸是否贴近第一显示屏220；感应装置222可以是红外传感器，通过红外线检测来确定人脸是否贴进第一显示屏220,当确定人脸是否贴进第一显示屏220时，感应装置222可以通知第一驱动单元211，第一驱动单元211根据感应装置222确定人脸贴近第一显示屏220时，向第二驱动单元212发送通知消息。第二驱动单元212接收到第一驱动单元211发送的通知消息后，进一步确定通话模组240是否正在通话，比如，第二驱动单元212可以根据显示屏上的用户执行的操作，通过其内部的处理单元确定通话模组240是否正在通话，当第二驱动单元212在接收到第一驱动单元211发送的通知消息且确定通话模组240正在通话时，在第二显示屏230预设图像。其中，预设图像可以是全黑图像，或者，模拟所述的电子设备的后壳。
在本发明实施例中，电子设备200还包括拍摄模组250，拍摄模组250用于与远端进行通话。其中，感应装置222还用于确定第一显示屏220前方是否存在拍摄对象；感应装置222可以是红外传感器，通过红外线检测来确定第一显示屏220前方是否存在拍摄对象,当确定第一显示屏220前方存在拍摄对象时，感应装置222可以通知第一驱动单元211，第一驱动单元211根据感应装置222确定第一显示屏220前方存在拍摄对象时，向第二驱动单元212发送通知消息。第二驱动单元212接收到第一驱动单元211发送的通知消息后，进一步确定拍摄模组250是否正在拍摄，比如，第二驱动单元212可以根据显示屏上的用户执行的操作，通过其内部的处理单元确定拍摄模组250是否正在拍摄，当第二驱动单元212在接收到第一驱动单元211发送的通知消息且确定拍摄模组250正在拍摄时，在第二显示屏230预设图像。其中，预设图像可以是全黑图像，或者，模拟所述的电子设备的后壳。
在本发明实施例中，电子设备200的第二显示屏可以是触摸屏，其中，第二驱动单元212在接收到第一驱动单元211发送的通知消息时，可以锁定第二显示屏230的触控功能，以防止误触控。
在本发明实施例中，电子设备200的第一显示屏210及第二显示屏220可以是触摸屏，此时，电子设备200还包括触控驱动电路260.该触控驱动电路260可以分时复用，以响应在第一显示屏220及第二显示屏230上的触控操作。比 如，当用户在第一显示屏220上进行触控操作而第二显示屏230上不存在触控操作时，触控电路260响应第一显示屏220上的触控操作，当用户在第一显示屏220上进行触控操作且第二显示屏230上也存在触控操作时，需要区分两次触控操作的触发时间，根据触控操作的触发时间先后次序来分别响应不同时间的触控操作，当用户在第一显示屏220上进行触控操作且第二显示屏230上同时也存在触控操作时，则可以预先设置不同显示屏上响应触控操作的优先级分别进行响应，比如，第一显示屏220上响应优先级高于第二显示屏230上，则触控驱动电路260优先响应第一显示屏220上的触控操作。
双屏同时工作时，电子设备的电量消耗多。此时，用户在第一显示屏210输入触控动作，第一驱动单元211检测到用户在第一显示屏210的触控动作，分析出该触控动作是指示关闭第二显示屏220的动作，于是，第一驱动单元211根据检测到的触控动作，向第二驱动单元212发送通知信息，第二驱动单元212根据该通知信息关闭第二显示屏，从而节省第二显示屏220的工作时所需能量。例如，用户在第一显示屏210启动关闭第二显示屏220的操作界面，并且在该操作界面选择关闭第二显示屏的选项，第一驱动单元211基于对该选项的选择而向第二驱动单元212发送用于指示第二驱动单元212关闭第二显示屏220的通知信息，第二驱动单元212基于该通知信息关闭第二显示屏220。
在一些实施例中，为了确定用户是否真正需要关闭第二显示屏220，防止误操作而错误关闭第二显示屏220，在关闭第二显示屏220时，第二驱动单元212向第一驱动单元211发送提醒信息，用户在第一显示屏210查看到该提醒信息，以决定是否真正需要关闭第二显示屏220。
若用户确定关闭第二显示屏220时，用户在第一显示屏210输入确定操作，第一显示屏210根据该确定操作分发出触发信号，第一驱动单元211在检测该触发信号时，向第二驱动单元212发送反馈信息，以使第二驱动单元212根据用户在第一显示屏210的触控动作、用户在第二显示屏220的触控动作以及反馈信息关闭第二显示屏210。
通过采用提醒和反馈机制，其能够提高用户体验，尽量避免一些误操作而引发的不良问题发生。
在一些实施例中，当电子设备200的电量不足时，为了延长此时电子设备200的电池续航能力和节约电源，第二驱动单元212访问电子设备的电源系统， 例如，第二驱动单元212按照一定频次，访问电源系统的充电管理芯片，从该充电管理芯片获知当前电池容量，当当前电池容量低于预警值，并且第二驱动单元212在接收到第一驱动单元211发送的通知信息时，关闭第二显示屏220的显示。因此，通过关闭第二显示屏220的工作，从而延长了电子设备200的电池续航能力。
在本发明实施例中，电子设备200还包括听筒270和/或按键280和/或摄像头290，其中，听筒270和/或按键280和/或摄像头290可以设置于电子设备200的正面，以实现电子设备在通话过程中的语音输入、文字输入或者拍摄过程中的图像输入。
需要说明的是，在本发明实施例中，电子设备的第一显示屏及第二显示屏的表述仅仅是为了方便说明的需要，比如，位于电子设备正面的显示屏称为第一显示屏，位于电子设备的背面的显示屏称为第二显示屏，但本领域普通人员应该知道，这并不用于限制本发明实施例。
在本发明实施例中，在通话过程中或拍摄过程中由第一驱动单元向第二驱动单元发送通知消息，并根据通知消息由第二驱动单元在第二显示屏预设图像，一方面可以实现不同显示屏之间通过驱动单元实现关联控制，另一方面可以在执行电子设备的功能过程中，显示用户预设的图像或锁定操作，保证了显示屏显示内容的信息安全或避免了误操作，进一步提升了用户体验。
