具体实施方式
为使本公开的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本公开作进一步详细的说明。
现有的可折叠显示设备为了方便使用，不管开合哪个显示屏都可以在打开设备后直接进入正常的使用状态。当可折叠显示设备的两个屏幕之间的夹角比较小时，若同时唤醒两个屏幕会造成两个屏幕的光线互射彼此干扰的问题。
本公开实施例提供一种屏幕唤醒方法，应用于可折叠显示设备(例如手机)，以解决相关技术中当可折叠显示设备的两个屏幕之间的夹角比较小时，若同时唤醒两个屏幕会造成光线互射彼此干扰的问题。该可折叠显示设备包括柔性显示面板，所述柔性显示面板可折叠，配置为通过连接构件连接的第一子显示屏及第二子显示屏。
参照图1可知，该方法包括下述步骤S100至S600。
S100，确定所述第一子显示屏及第二子显示屏中相对静止的子显示屏及相对运动的子显示屏；
这一步骤中，为便于后续确定唤醒方式及唤醒顺序，首先需要判断第一子显示屏及第二子显示屏中哪个为相对静止的子显示屏，哪个为相对运动的子显示屏。
S200，确定所述第一子显示屏及第二子显示屏之间的夹角；
S300，判断所述夹角是否大于第一预设角度；
S400，若是，则唤醒所述相对静止的子显示屏；
在上述两个步骤中，当设备夹角满足第一预设角度时(例如：20度)，则只唤醒一边屏幕，参照图6所示，当用户打开处于折叠状态的设备时，通常首先看到相对静止的子显示屏(参加图6中B)。因此当用户将折叠状态的设备打开到第一预设角度时，首先只唤醒相对静止的子显示屏B，A屏暂时不唤醒保持息屏，避免亮屏同时亮，造成反光。步骤S400之后，所述方法还包括步骤S500和S600。
根据所述夹角与亮度的对应关系，调节所述相对静止的子显示屏的亮度，其中，所述对应关系为，亮度随着夹角增大而增高。在较小夹角的情况下， 用户看不到太多相对静止的子显示屏的内容，子显示屏的亮度较低可以给眼球带来一个渐变的适应过程。
在一些可选实施例中，S400之后可以进行S401，按照第一特定规则调节所述相对静止的子显示屏的亮度(参照图2)。所述第一特定规则为：根据所述第一子显示屏与所述第二子显示屏之间夹角的不断增大按照第一预设速率逐渐提高所述相对静止的子显示屏的亮度。
具体地，为了避免刚唤醒的显示屏亮度过高影响用户的使用体验，实际应用中，显示屏刚被唤醒时的亮度较弱，且根据第一子显示屏与第二子显示屏之间夹角的不断增大按照一定速率逐渐提高显示屏的亮度，以慢慢适应用户感官。该速率可以根据实际需要预先设定好，且应该能够根据用户打开设备速度的快慢进行调节。
S500，判断所述夹角是否大于第二预设角度，所述第二预设角度大于所述第一预设角度。
S600，若是，则唤醒所述相对运动的子显示屏。
在上述两个步骤中，当两个子屏幕之间的夹角超过第二预设角度(例如：90度)，则在B亮屏的基础上唤醒A：此时两边屏幕相互之间光线干扰已经不强，而且用户可以同时看到两个屏幕。
在一些可选实施例中，S600之后该方法还包括：
根据所述夹角与亮度的对应关系，调节所述相对运动的子显示屏的亮度，其中，所述对应关系为，亮度随着夹角增大而增高。
具体地，S600之后可以进行S601，按照第二特定规则调节所述相对运动的子显示屏的亮度(参照图2)。所述第二特定规则为：根据所述第一子显示屏与所述第二子显示屏之间夹角的不断增大按照第二预设速率逐渐提高所述相对运动的子显示屏的亮度。
这一步骤的具体实现方式参照S401，此处不再赘述。值得注意的是，在这个步骤中，与相对静止的子显示屏相比，相对运动的子显示屏唤醒的较晚，此时前者的亮度已经达到了一定强度。因此，考虑到用户已经适应了较强的亮度，所述第二特定规则对应的起始亮度和亮度的递增速率同第一特定规则相比可以适当提高，且实际应用时可以根据具体情况区别设计。
可选地，相对同一夹角，所述相对静止的子显示屏的亮度比所述相对运动的子显示屏的亮度高。一般来说，用户的视线集中在相对静止的子显示屏上，相对运动的子显示屏的亮度比相对静止的子显示屏的亮度低，则相对运动的子显示屏不会太亮，投射到相对静止的子显示屏的光线较低，不会对相对静止的子显示屏产生太大干扰，反光程度较小。
参照图2可知，S100可以包括如下步骤：
S101，通过传感器分别获得第一子显示屏及第二子显示屏的角度变化率；
S102，确定所述角度变化率大的子显示屏为相对运动的子显示屏，且角度变化率小的子显示屏为相对静止的子显示屏。
上述两个步骤例如可以通过在某个子显示屏上或者两个子显示屏上嵌入的传感器(例如：三轴陀螺仪)来实现。通过三轴陀螺仪分别得到两个子显示屏的角度变化率，通过对比角度变化率的大小，确定所述角度变化率较大的子显示屏为相对运动的子显示屏，且角度变化率较小的子显示屏为相对静止的子显示屏。
相应地，S200同样可以利用所述传感器(例如：三轴陀螺仪)实现，根据传感器获得的角度信息，直接得到显示屏之间的夹角。
本公开实施例提供的屏幕唤醒方法的具体实现方式例如为：
首先，在可折叠显示设备的子显示屏上嵌入三轴陀螺仪，通过陀螺仪得到两个子显示屏的角度信息，通过对比两个子显示屏的角度变化率可以知道哪一个屏相对静止(角度变化率相对较小)，哪一个屏相对运动(角度变化率相对较大)。在日常应用中，处于折叠状态的设备放置在台面时，用户会将一个子显示屏固定，另一个子显示屏相对运动地打开设备。
接下来，在折叠设备开启的过程中，相对静止的子显示屏会优先被用户看到，因此可以将相对静止的子显示屏作为主屏幕唤醒点亮，相对运动的子显示屏暂时不唤醒，并将相对运动的子显示屏保持息屏，避免两个子显示屏同时点亮，造成反光。
进一步地，当相对运动的子显示屏与相对静止的子显示屏之间的角度满足第一预设角度时，例如20度，则唤醒相对运动的子显示屏，亮屏显示。为了尽可能降低功耗以及提高用户的视觉体验，两个子显示屏在亮屏后屏幕亮 度由暗到亮，跟随夹角的变化而提高亮度。
随着子显示屏之间夹角的不断增大，当夹角超过第二预设角度时，例如90度时，此时两个子显示屏相互之间的光线干扰已经不明显，而且用户可以同时看到两个屏幕，所以相对静止的子显示屏亮屏的基础上，唤醒相对运动的子显示屏。
与相关技术相比，本公开实施例至少可以达到如下效果：
提供一种计算设备当前打开角度的方法，利用传感器(三轴陀螺仪)，判断当设备被打开到一个较小角度时，只唤醒一边屏幕并根据角度动态调节屏幕的亮度；当设备打开到一定角度时，才唤醒另一个屏幕；从而避免小角度时唤醒两个屏幕使得光线相互投射形成的反光干扰问题。
本公开的一些实施例提供了一种屏幕唤醒方法，参照图3所述，该方法包括如下步骤S100至S104、S200至S204和S300至S600。
S100，确定所述第一子显示屏及第二子显示屏中相对静止的子显示屏及相对运动的子显示屏(图中未画出)。
这一确定步骤包括如下子步骤：
S103，通过第一子显示屏上的摄像头获得图像信息；
S104，根据所述图像信息中的人脸信息确定相对静止的子显示屏及相对运动的子显示屏。
上述两个步骤例如可以通过设置在设备上的摄像头实现。实际应用中，摄像头通常会设置在某个子显示屏上。此时，不管设置有摄像头的子显示屏为相对静止的子显示屏还是相对运动的子显示屏，至少都可以通过摄像头得到图像信息，然后通过图像信息中的人脸信息(例如用户头部方向及运动情况)判断并确定相对静止的子显示屏及相对运动的子显示屏。例如，参照图6所示，当用户将折叠设备打开到某一角度，看向设备的B部分；此时，若摄像头位于A，则获得的用户头部的图像正向，此时，若用户头部图像不断变化(例如变大)，此时便可确定B为相对静止的子显示屏，A为相对运动的摄像头。
S200，确定所述第一子显示屏及第二子显示屏之间的夹角(图中未画出)；
确定了相对运动以及相对静止的子显示屏后，这一步骤用于确定两个子 显示屏之间的夹角。具体地，可以包括如下子步骤S201至S204。
S201，获取所述第一子显示屏上的摄像头拍摄所述第二子显示屏获得的图像信息。
例如，参照图6所示，当用户将折叠设备打开到某一角度，看往设备的B(相对静止的子显示屏)，摄像头位于A(相对运动的子显示屏)，且摄像头可以获得B(相对静止的子显示屏)的图像信息。
S202，根据所述图像信息，计算所述第二子显示屏在所述摄像头中成像的尺寸。
具体的，根据所述B(相对静止的子显示屏)的图像信息，从摄像头的图像数据中提取手机轮廓，计算出B(相对静止的子显示屏)成像的大小。
S203，通过成像公式得到第一子显示屏及第二子显示屏之间的距离；
这一步骤中的成像公式为：
Figure PCTCN2018081893-appb-000001
其中，P为B(相对静止的子显示屏)在摄像头中成像的尺寸(长度)，Q为可折叠显示设备的实际大小，R为摄像头光圈的大小R，D为相距，L为物距。在P、Q、D和R已知的情况下，可以通过成像公式反推出L，得到A和B之间的距离。
S204，通过三角函数得到第一子显示屏及第二子显示屏之间的夹角。
根据S203获得的A和B之间的距离，便可以使用三角函数得到两个子显示屏之间的夹角。
S300，判断所述夹角是否大于第一预设角度；
S400，若是，则唤醒所述相对静止的子显示屏；
S500，判断所述夹角是否大于第二预设角度；
S600，若是，则唤醒所述相对运动的子显示屏。
其中，S300和S600可以参照上述实施例所述内容，此处不再赘述。
同样地，S400之后还可以包括S401，S600之后可以包括S601，参照上述实施例，此处不再赘述。
本公开实施例提供的屏幕唤醒方法的具体实现方式例如为：
首先，通过可折叠显示设备的摄像头，获得包含用户头像的图像信息， 根据所述图像信息中的人脸信息确定哪一个屏相对静止，哪一个屏相对运动。然后，再通过摄像头获得的其中一个子显示屏的图像信息通过成像公式以及三角函数计算得到两个子显示屏之间的夹角。
接下来，在折叠设备开启的过程中，相对静止的子显示屏会优先被用户看到，因此可以将相对静止的子显示屏作为主屏幕唤醒点亮，相对运动的子显示屏暂时不唤醒，并将相对运动的子显示屏保持息屏，避免两个子显示屏同时点亮，造成反光。
进一步地，当相对运动的子显示屏与相对静止的子显示屏之间的角度满足第一预设角度时，例如20度，则唤醒相对运动的子显示屏，亮屏显示。为了尽可能降低功耗以及提高用户的视觉体验，两个子显示屏在亮屏后屏幕亮度由暗到亮，跟随夹角的变化而提高亮度。
随着子显示屏之间夹角的不断增大，当夹角超过第二预设角度时，例如90度时，此时两个子显示屏相互之间的光线干扰已经不明显，而且用户可以同时看到两个屏幕，所以相对静止的子显示屏亮屏的基础上，唤醒相对运动的子显示屏。

提供一种计算设备当前打开角度的方法，利用设备安装的摄像头，判断当设备被打开到一个较小角度时，只唤醒一边屏幕并根据角度动态调节屏幕的亮度；当设备打开到一定角度时，才唤醒另一个屏幕；从而避免小角度时唤醒两个屏幕使得光线相互投射形成的反光干扰问题。
