  • Example 1 when the electronic device stops closing at time D, because the inner screen angle is greater than the "unfolding and folding angle" (for example, 40°) and less than the "unfolding and folding angle + supplementary angle 2" (for example, 60°), in Example 1, it is determined that the device form of the electronic device at this time is a semi-unfolded state rather than a folded state.

背景技术
目前，电子设备可以折叠(也可以称为闭合)、展开(也可以称为打开)，且可以包括两个不同侧的显示屏。该两个显示屏中的一个显示屏可以被称为内屏，另一个显示屏可以被称为外屏。其中，内屏可以理解为：电子设备未折叠时与前置摄像头在同一侧的显示屏。外屏可以理解为：电子设备未折叠时与后置摄像头在同一侧的显示屏。其中，内屏可以是具有折叠与展开功能的显示屏，在电子设备折叠时，内屏也被折叠。在电子设备展开时，内屏也被展开。
闭合电子设备以及展开电子设备时，对于两个显示屏的点亮与熄灭，一种合理的设计包括：电子设备的初始状态为展开，闭合电子设备时，可以尽快使得内屏熄灭且外屏点亮。电子设备的初始状态为闭合，在展开电子设备时，可以尽快使得外屏熄灭，内屏点亮。通常来说，这样的设计符合用户闭合电子设备以及展开电子设备时亮屏的预期。
闭合电子设备以及展开电子设备时，如何更好的控制两个显示屏的点亮与熄灭，是值得关注的。
发明内容

第一方面，本申请提供了控制亮屏的方法，应用于屏幕可折叠的电子设备，该电子设备包括内屏和外屏，该内屏可折叠形成第一屏和第二屏，该方法包括：该电子设备的初始状态为闭合，且该内屏以及该外屏均熄灭的情况下，该电子设备展开到该第一夹角大于或者等于第一角度的情况下，该电子设备点亮该内屏，保持该外屏熄灭；该第一夹角为该第一屏和该第二屏的夹角，在该电子设备的初始状态为闭合，展开该电子设备的过程中，该第一夹角变大；在该电子设备的初始状态为展开，闭合该电子设备的过程中，该第一夹角变小；该电子设备的初始状态为闭合，且该内屏、该外屏中至少一个点亮的情况下，该电子设备展开到该第一夹角大于或者等于该第一角度的情况下，该电子设备处于内屏点亮，外屏熄灭的状态；该电子设备的初始状态为展开，且该内屏、该外屏中至少一个点亮的情况下，该电子设备闭合到该第一夹角小于或者等于第二角度的情况下，该电子设备处于该外屏点亮，该内屏熄灭的状态；其中，该第二角度大于该第一角度。

上述实施例中，初始状态为闭合，且内屏熄灭、外屏点亮的情况下，打开电子设备到内屏夹角大于或者等于第一角度(例如10°)时，即可触发内屏点亮，且外屏熄灭。此时，用户期望展开使用电子设备的内屏，则在可以在较小角度尽快使得电子设备处于内屏点亮，且外屏熄灭的状态，符合用户的使用习惯。
结合第一方面，在一些实施例中，在该内屏、该外屏均点亮的情况下，该电子设备展开到该第一夹角大于或者等于第一角度之后，还包括：该电子设备熄灭该外屏。

上述实施例中，初始状态为展开，且内屏以及外屏均点亮的情况下，闭合电子设备到内屏夹角小于或者等于第二角度(例如60°)时，即可触发内屏熄灭，且保持内屏点亮。此时，用户期望闭合使用电子设备的外屏，则在可以在较大角度尽快使得电子设备处于外屏点亮，且内屏熄灭的状态，符合用户的使用习惯。
结合第一方面，在一些实施例中，在该内屏点亮、该外屏熄灭的情况下，该电子设备闭合到该第一夹角小于或者等于第二角度之后，还包括：该电子设备熄灭该内屏，点亮该外屏。
上述实施例中，初始状态为展开，且内屏点亮，外屏熄灭的情况下，闭合电子设备到内屏夹角小于或者等于第二角度(例如60°)时，即可触发内屏熄灭，内屏点亮。此时，用户期望闭合使用电子设备的外屏，则在可以在较大角度尽快使得电子设备处于外屏点亮，且内屏熄灭的状态，符合用户的使用习惯。
结合第一方面，在一些实施例中，该方法还包括：该第一夹角大于或者等于该第一角度小于该第三角度，且该电子设备处于内屏点亮，外屏熄灭的状态时，该电子设备闭合到该第一夹角小于或者等于第四角度的情况下，该电子设备熄灭该内屏，点亮该外屏；该第四角度小于该第一角度。
上述实施例中，第三角度可以为实施例中涉及的预设角度3，例如可以为“折叠切展开角度+补充角度1”。第四角度可以为实施例中涉及的预设角度5，例如“远离切接近”角度。该第一夹角处于第一角度(例如10°)以及第三角度(例如65°)之间时，在内屏点亮的情况下，再闭合电子设备到第四角度(例如5°)时，表示用户期望闭合电子设备，使用外屏，不使用内屏。则在内屏夹角小于或者等于第四角度(例如5°)时，熄灭内屏，点亮外屏，符合用户使用习惯。
结合第一方面，在一些实施例中，该内屏以及该外屏均熄灭的情况下，该电子设备展开到该第一夹角在第一时刻大于或者等于该第三角度，该电子设备点亮该内屏，保持该外屏熄灭之后，该方法还包括：该电子设备闭合到该第一夹角在第二时刻小于该第二角度时，该电子设备熄灭该内屏，点亮该外屏；该第二时刻晚于该第一时刻。
结合第一方面，在一些实施例中，该第二时刻与该第一时刻的时间差小于或者等于预设时长。
结合第一方面，在一些实施例中，该电子设备的第一传感器设定的第一形态包括该第一夹角小于或者等于该第一角度，设定的第二形态包括该第一夹角大于该第一角度小于第二角度；该电子设备的第二传感器设定的第一形态包括该第一夹角小于该第二角度；该内屏、该外屏中至少一个点亮时，该电子设备开启该第二传感器；该电子设备的初始状态为闭合，且该内屏熄灭、该外屏点亮的情况下，该电子设备展开到第一夹角大于或者等于该第一角度之后，该电子设备点亮该内屏，熄灭该外屏，具体包括：该电子设备展开到该内屏第一夹角大于或者等于该第一角度的情况下，该电子设备基于该第一传感器确定该电子设备的设备形态由该第一形态变更为该第二形态时，该电子设备点亮该内屏，熄灭该外屏；其中，该第二形态不同于该第一形态；该第一形态用于指示该电子设备折叠，该第二形态用于指示该电子设备展开。
上述实施例中，第一传感器可以为实施例中的霍尔传感器，第二传感器可以为实施例中的姿态传感器，第一形态可以为实施例中涉及的折叠态，第二形态可以为实施例中涉及的展开态(例如半展开态、全展开态、远离态映射的展开态)。
相比于使用霍尔传感器为辅助，姿态传感器为主的方案。该实施例中，姿态传感器和 霍尔传感器同等重要，在姿态传感器工作的情况下，电子设备也可以基于霍尔传感器上报的设备形态控制亮屏。其中，在小角度开合里基于霍尔传感器确定设备形态，在大角度开合里基于姿态传感器确定设备形态。因此，在电子设备的初始状态闭合，且内屏熄灭，外屏点亮的情况下，虽然姿态传感器工作，但是由于霍尔传感器也起作用，则电子设备展开到较小角度(第一角度，例如10°)时，也可以基于该霍尔传感器确定电子设备的设备形态为在展开态，则使得内屏点亮，外屏熄灭。在闭合时，展开电子设备的过程中，响应较快，增强用户体验。但是，以霍尔传感器为辅助，姿态传感器为主的方案达不到该效果。因为，在亮屏时，姿态传感器开启，电子设备不对霍尔上报的设备形态进行处理，及时电子设备展开到了第一角度(例如10°)，虽然霍尔传感器确定设备形态为展开态，但是电子设备并不会处理，会继续等待电子设备的内屏夹角展开到姿态传感器上报设备形态时(例如展开到45°)，才会使得内屏点亮，该外屏熄灭。
相比于使用只使用霍尔传感器的方案。在该实施例中，引入了姿态传感器，在大角度开合里基于姿态传感器确定设备形态。因此，在电子设备的初始状态展开，且内屏点亮，外屏熄灭的情况下，则电子设备闭合到较大角度(第二角度，例如60°)时，可以基于该姿态传感器确定电子设备的设备形态为在闭合态，则使得内屏熄灭，外屏点亮。在展开时，闭合电子设备的过程中，响应较快，增强用户体验。但是，只使用霍尔传感器的方案不可以达到该效果。因为，霍尔传感器的工作区间在较小角度范围(例如5°-10°)里，在电子设备闭合到第二角度(例如60°)时，霍尔传感器并不会上报设备形态，因为无法基于霍尔传感器实现内屏夹角在闭合到第二角度(例如60°)时，即使得内屏熄灭，外屏点亮。
结合第一方面，在一些实施例中，该电子设备的初始状态为闭合，在该第一夹角小于第一角度且该内屏以及该外屏均熄灭的情况下，该电子设备展开到该第一夹角大于或者等于该第一角度，该电子设备点亮该内屏，保持该外屏熄灭，具体包括：该电子设备展开到该第一夹角大于或者等于该第一角度的情况下，该电子设备基于该第一传感器确定该电子设备的设备形态由该第一形态变更为该第二形态时，该电子设备点亮该内屏，保持该外屏熄灭；该电子设备点亮该内屏，保持该外屏熄灭之后，该方法还包括：该电子设备开启该第二传感器；该第二传感器获取第一事件，该第一事件用于指示该电子设备的设备形态；在该第二传感器确定该第一事件不为首帧事件，或者该第一事件为首帧事件且该第一事件指示该电子设备的设备形态为该第二形态的情况下，该电子设备熄灭该内屏，点亮该外屏；在该第二传感器确定该第一事件为首帧事件且该第一事件指示该电子设备的设备形态为该第一形态的情况下，该电子设备保持该内屏点亮，该外屏熄灭。
上述实施例中，在一些实施例中，闭合时展开电子设备的情况下，在霍尔传感器上报展开态之后，会使得内屏点亮，此时，可以开启姿态传感器，对于姿态传感器上报的首帧事件为折叠态的情况下，电子设备可以不对该首帧事件进行处理，避免在展开电子设备的过程中内屏点亮之后，又触发内屏熄灭。
结合第一方面，在一些实施例中，该第二传感器确定该第一事件不为首帧事件，或者该第一事件为首帧事件且该第一事件指示该电子设备的设备形态为该第二形态时，该电子 设备熄灭该内屏，点亮该外屏，具体包括：在该第二传感器确定该第一事件为首帧事件，该第一事件指示该电子设备的设备形态为该第一形态，且该第一夹角小于第五角度的情况下，该电子设备熄灭内屏，点亮外屏；在该第二传感器确定该第一事件为首帧事件且该第一事件指示该电子设备的设备形态为该第一形态的情况下，不对该第一事件进行处理，具体包括：该第二传感器确定该第一事件为首帧事件，该第一事件指示该电子设备的设备形态为该第一形态，且该第一夹角大于该第五角度的情况下，该电子设备保持该内屏点亮，该外屏熄灭。
上述实施例中，第五角度可以为实施例中涉及的预设角度5(例如4°)。闭合时展开电子设备的情况下，在实际为闭合，但是霍尔传感器上报了远离态(即霍尔认为电子设备参考)的情况下，可以认为霍尔失效了，此时，姿态传感器可以在确定夹角小于预设角度7的情况，对首帧事件进行处理，触发内屏熄灭，外屏点亮。这样，可以在小角度开合时，霍尔失效的情况下，仍然基于姿态传感器准备判断电子设备的设备形态，控制亮屏。
结合第一方面，在一些实施例中，该方法还包括：该第一夹角大于或者等于该第一角度小于该第三角度，且该电子设备处于内屏点亮，外屏熄灭的状态时，该电子设备闭合到该第一夹角小于或者等于该第四角度的情况下，该电子设备基于该第一传感器确定该电子设备的设备形态从该第二形态变更至该第一形态时，该电子设备熄灭该内屏，点亮该外屏。
结合第一方面，在一些实施例中，该电子设备的初始状态为展开，且该内屏以及该外屏均熄灭的情况下，闭合该电子设备到小于该第四角度，该电子设备保持该外屏熄灭以及该内屏熄灭，其中，该第角度小于该第一角度。
上述实施例中，初始状态为展开，且内屏熄灭，外屏熄灭的情况下，闭合电子设备到内屏夹角小于或者等于第四角度(例如5°)时，可以保持内屏以及内屏均熄灭。此时，用户在内屏以及外屏均熄灭时闭合电子设备，则表示用户此时不期望再使用电子设备，则在闭合时保持外屏以及内屏均熄灭，符合用户的使用习惯。

具体实施方式
本申请以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括复数表达形式，除非其上下文中明确地有相反指示。还应当理解，本申请中使用的术语“和/或”是指并包含一个或多个所列出项目的任何或所有可能组合。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
现有的方案中，通过霍尔传感器确定电子设备的展开与折叠情况。电子设备从折叠到展开时，霍尔传感器可以在内屏的夹角(也可以称为内屏夹角)展开到角度1(例如10°)时即可确定电子设备展开了，则电子设备可以触发外屏熄灭且内屏点亮。但是，由于霍尔传感器设计时的局限性：在电子设备展开时闭合电子设备的过程中，霍尔传感器在内屏夹角闭合到小于或者等于角度2(例如5°)时才可以确定电子设备折叠了，这时电子设备触发内屏熄灭且外屏点亮显得“为时过晚”，不符合用户希望在闭合电子设备时希望尽快触发内屏熄灭且外屏点亮的预期。
该现有的方案中，通过单一的霍尔传感器来控制屏幕的点亮与熄灭。由于霍尔传感器的工作区间在较小的角度范围里，该角度范围通常为内屏夹角处于5°至10°时。其中，工作区间是指霍尔传感器可以上报设备形态的角度范围。因此，电子设备在小角度里开合时，霍尔传感器表现良好，在大角度开合时，表现较差：只使用霍尔传感器虽然可以在电子设备的初始状态为闭合，打开电子设备的过程中，较快(例如展开到10°)的使得内屏点亮，外屏熄灭。但是，在电子设备的初始状态为展开，闭合电子设备的过程中，却不可 以较快的使得内屏熄灭，外屏点亮。例如，闭合电子设备，在内屏夹角闭合到5°时才可以使得内屏熄灭，外屏点亮。即，在展开时，闭合电子设备的过程中，霍尔传感器表现不好，反应较慢，影响用户体验。
本申请实施例中提供了控制亮屏的方法。可以使用霍尔传感器以及姿态传感器配合，在不同的角度范围基于不同的姿态传感器确定设备形态，快速响应电子设备的展开以及闭合，控制屏幕的点亮与熄灭，提升用户体验感。在该方法中，电子设备在小角度里开合时，仍然基于霍尔传感器控制屏幕的点亮与熄灭，保留了霍尔传感器的优点。但是，大角度开合时，引入姿态传感器，电子设备可以基于姿态传感器控制屏幕的点亮与熄灭，使得电子设备较快(例如闭合到40°或者60°)的响应闭合，使得内屏熄灭，外屏点亮。这样可以弥补霍尔传感器的缺陷。其原因在于，姿态传感器的工作区间相比于霍尔传感器可以更大，其可以在较大的角度范围(例如40°至65°)里确定电子设备的设备形态，使得电子设备基于该设备形态控制屏幕的点亮与熄灭。
该方法可以应用于具有纵向折叠或横向折叠特性的电子设备，且该电子设备中包括两个不同侧的显示屏。该两个显示屏中的一个显示屏可以被称为内屏，另一个显示屏可以被称为外屏。电子设备可以按照预设规则，通过霍尔传感器以及姿态传感器确定电子设备的设备形态变化，使得更多场景下，电子设备在展开或者折叠时实现合理亮屏。
在一些可能的情况下，电子设备的设备形态可以包括展开态、折叠态。其中，展开态又可以包括半展开态以及全展开态。
下面对配置纵向折叠特征的电子设备的设备形态进行介绍。
实例性的，图1A-图1D示出了本申请实施例提供的一种具有纵向折叠特性的电子设备的设备形态示意图，纵向折叠的折叠边垂直于电子设备的顶部边缘线(为便于描述，将顶部边缘线简称为顶边)和底部边缘线(为便于描述，将底部边缘线简称为底边)。
其中，图1A是可纵向折叠电子设备的一种展开形态的示意图。如图1A所示，电子设备没有进行折叠。内屏为电子设备未折叠时与前置摄像头在同一侧的显示屏。此时，可以看作内屏夹角为180°。其中，内屏夹角可以看作：沿着折叠边将内屏分为A屏和B屏，A屏与B屏之间形成的夹角可以称为内屏夹角。
按照图1A所示的方向11a和/或方向11b进行折叠，内屏夹角从180°至预设角度1(例如145°)之间的设备形态都可以称为电子设备的全展开态。
按照图1A所示的方向11a和/或方向11b进行折叠，内屏夹角从预设角度1(例如145°)至预设角度2(例如40°)之间的夹角都可以看作电子设备的半展开态。其中一种半展开态的示意图可以参考图1B所示。内屏夹角(α)可以取值为预设角度1至预设角度2之间的任一夹角。其中，预设角度1大于预设角度2。
按照图1B所示的方向11a和/或方向11b进行折叠。内屏夹角从预设角度2(例如40°)至0°之间的夹角都可以看作电子设备的折叠态。其中一种折叠态的示意图可以参考图1C所示。内屏夹角(α)可以取值为预设角度2至0之间的任一夹角。电子设备处于折叠态时，可以触发内屏熄灭，外屏点亮。其中，外屏可以看作电子设备未折叠时与后置摄像头在同一侧的显示屏。
按照图1C所示的方向11a和/或方向11b进行折叠。使得内屏夹角为0°，如图1D所示子设备完全闭合。此时，电子设备的设备形态也可以被称为折叠态。图1D中，A屏和B屏相对，对用户不可见。
应该理解的是，图1A-图1D中是以电子设备的初始状态为展开(例如等于180°或者接近180°等展开态下的角度)，闭合电子设备为例进行说明的。
其中，闭合电子设备是指使得电子设备的内屏夹角逐渐变小。例如使得内屏夹角逐渐接近0°或者等于0°。初始状态为展开是指电子设备闭合电子设备之前，电子设备的设备形态为展开态，通常来说内屏夹角大于预设角度2(例如40°)，例如内屏夹角为180°时可以看作一种展开态。
参考图1A-图1D的内容与描述，对于电子设备的初始状态为闭合(等于0°或者接近0°)，展开电子设备的情况，电子设备的设备形态包括：内屏夹角在0°至预设角度3(例如45°)时，电子设备的设备形态可以为折叠态。内屏夹角在预设角度3(例如45°)至预设角度4(例如150°)时，电子设备的设备形态可以为半展开态。内屏夹角在预设角度4(例如150°)至180°时，电子设备的设备形态可以为全展开态。其中，预设角度3小于预设角度4。预设角度3可以和预设角度2相等，也可以和预设角度2不相等。预设角度1可以和预设角度4相等，也可以和预设角度4不相等。本申请实施例对此不做限定。
其中，展开电子设备是指使得电子设备的内屏夹角逐渐变大。例如使得内屏夹角逐渐接近180°或者等于180°。初始状态为闭合是指展开电子设备之前，电子设备的内屏夹角接近或者等于0°，通常来说小于10°。
下面对配置横向折叠特性的电子设备的设备形态进行介绍。
示例性的，图2示出了本申请实施例提供的一种具有横向折叠特性的电子设备示意图。内屏为电子设备未折叠时与前置摄像头在同一侧的显示屏。外屏(未示出)可以看作电子设备未折叠时与后置摄像头在同一侧的显示屏。未折叠时，可以看作内屏夹角为180°。其中，内屏夹角(α)可以看作：沿着折叠边将内屏分为A屏和B屏，A屏与B屏之间形成的夹角可以称为内屏夹角。与纵向折叠的电子设备的区别在于：横向折叠屏的折叠边平行于电子设备的顶边和底边。横向折叠的电子设备的设备形态的其他描述与前述图1A-图1D相同，可以参考前述图1A-图1D的描述，此处不再赘述。
在一些可能的情况下，电子设备的设备形态除了前述涉及的折叠态、半展开态以及全展开态以外，还包括接近态以及远离态。
以电子设备的初始状态为闭合，展开电子设备时为例对接近态以及远离态进行说明。此时，接近态包括内屏夹角在0°至预设角度5(例如10°)之间时电子设备的形态。远离态包括内屏夹角在预设角度5(例如10°)至180°之间时电子设备的形态。其中，预设角度5小于预设角度2。
以电子设备的初始形态为展开，闭合电子设备为例对接近态以及远离态进行说明。此时，远离态包括内屏夹角在180°至预设角度6(例如5°)之间时电子设备的形态。接近态包括内屏夹角在预设角度6(例如5°)至0°之间时电子设备的形态。其中，预设角度 6小于预设角度2。该预设角度5与预设角度6之间的大小关系可以没有限定，但是通常来说，该预设角度5可以大于预设角度6。
在一些可能的情况下，电子设备可以通过霍尔传感器以及姿态传感器确定电子设备的设备形态。例如，姿态传感器以及霍尔传感器都可以基于内屏夹角等数据确定设备形态。通常来说，霍尔传感器在内屏夹角较小(例如小于等于10°)时可以上报设备形态，姿态传感器在内屏夹角较大(例如大于等于45°)时可以上报设备形态。电子设备在霍尔传感器以及姿态传感器上报设备形态时，才可以确定设备形态，后续基于该设备形态控制屏幕(包括内屏、外屏)的点亮以及熄灭。且霍尔传感器以及姿态传感器上报设备形态的时机包括：启动后的第一帧可以上报(一帧就是一个设备形态)，从第二帧开始，在检测到电子设备的设备形态相比于前一帧发生变化时可以上报。
基于以上描述的霍尔传感器和姿态传感器的物理特性。在一些可能的情况下，姿态传感器可以用于确定电子设备的设备形态为：折叠态、半展开态以及全展开态中的一个。霍尔传感器可以用于确定电子设备的设备形态为：接近态或者远离态中的一个。
为了便于描述，后文中可以将姿态传感器上报的设备形态称为姿态事件。将霍尔传感器上报的设备形态称为霍尔事件。
图3示出了姿态传感器上报姿态事件的过程。
下面结合图3对姿态传感器上报姿态事件的过程进行示例性描述。
如图3中(1)所示，在内屏夹角为0°至预设角度2(例如40°)之间时，姿态传感器可以确定电子设备的设备形态为折叠态。在内屏夹角为预设角度3(例如45°)至预设角度1(例如145°)之间时，姿态传感器可以确定电子设备的设备形态为半展开态。在内屏夹角为预设角度4(例如150°)至180°之间时，姿态传感器可以确定电子设备的设备形态为全展开态。
其中，在内屏夹角预设角度2(例如40°)至预设角度3(例如45°)之间时，电子设备的设备形态也可以被称为跟随态1。跟随态1用于表示：如果前一帧为折叠态，内屏夹角在预设角度2(例如40°)至预设角度3(例如45°)之间时，姿态传感器获取的当前帧也为折叠态。如果前一帧为半展开态，内屏夹角在预设角度2(例如40°)至预设角度3(例如45°)之间时，姿态传感器获取的当前帧也为半展开态。即可以理解为，如图3中(2)所示，在电子设备的初始状态为闭合，展开电子设备时，内屏夹角在预设角度2(例如40°)至预设角度3(例如45°)之间时，姿态传感器可以确定电子设备的设备形态为折叠态。如图3中(3)所示，在电子设备的初始状态为展开，闭合电子设备时，内屏夹角在预设角度2(例如40°)至预设角度3(例如45°)之间时，姿态传感器可以确定电子设备的设备形态为半展开态。
在内屏夹角预设角度1(例如145°)至预设角度4(例如150°)之间时，电子设备的设备形态也可以被称为跟随态2。跟随态2用于表示：如果前一帧为半展开态，内屏夹角在预设角度1(例如145°)至预设角度4(例如150°)之间时，姿态传感器获取的当前帧也为半展开态。如果前一帧为全展开态，内屏夹角在预设角度1(例如145°)至预设角度4(例如150°)之间时，姿态传感器获取的当前帧也为全展开态。即可以理解为，如 图3中(2)所示，在电子设备的初始状态为闭合，展开电子设备时，内屏夹角在预设角度1(例如145°)至预设角度4(例如150°)之间时，姿态传感器可以确定电子设备的设备形态为半展开态。如图3中(3)所示，在电子设备的初始状态为展开，闭合电子设备时，内屏夹角在预设角度1(例如145°)至预设角度4(例如150°)之间时，姿态传感器可以确定电子设备的设备形态为全展开态。
姿态传感器上报设备形态的时机包括：启动后的第一帧(一帧就是一个设备形态)可以上报，从第二帧开始，在检测到电子设备的设备形态相比于前一帧发生变化时可以上报。
例如，如图3中(2)所示，黑色三角形符号所在的位置可以是姿态传感器上报姿态事件的示例性时机。在闭合时展开电子设备的情况下，内屏夹角从小于预设角度3变化到大于预设角度3的过程中，电子设备的设备形态从折叠态变化到半展开态，则姿态传感器可以上报一帧设备形态(此时为半展开态)。内屏夹角从预设角度3至预设角度4之间的角度变化到大于预设角度4的过程中，电子设备的设备形态从半展开态变化到全展开态，则姿态传感器可以上报一帧设备形态(此时为全展开态)。应该理解的是，在内屏夹角小于预设角度3时才启动姿态传感器，则启动后的第一帧设备形态(此时为折叠态)也可以上报，其中一个上报的时机可以在图3中(2)所示出的白色正方形处。
再例如，如图3中(3)所示，三角形符号所在的位置可以是姿态传感器上报姿态事件的示例性时机。在展开时闭合电子设备的情况下，内屏夹角从大于预设角度1变化到小于预设角度1的过程中，电子设备的设备形态从全展开态变化到半展开态，则姿态传感器可以上报一帧设备形态(此时为半展开态)。内屏夹角从预设角度1至预设角度2之间的角度变化到小于预设角度2的过程中，电子设备的设备形态从半展开态变化到折叠态，则姿态传感器可以上报一帧设备形态(此时为折叠态)。应该理解的是，在内屏夹角大于预设角度1时才启动姿态传感器，则启动后的第一帧设备形态(此时为全展开态)也可以上报，其中一个上报的时机可以在图3中(3)所示出的白色正方形处。
其中，闭合时展开电子设备是指电子设备的初始状态为展开，闭合电子设备的过程。展开时闭合电子设备是指电子设备的初始状态为闭合，展开电子设备的过程。
图4示出了霍尔传感器上报霍尔事件的过程。
下面结合图4对霍尔传感器上报霍尔事件的过程进行实例性描述。
如图4中(1)所示，在内屏夹角为0°至预设角度6(例如5°)之间时，霍尔传感器可以确定电子设备的设备形态为接近态。在内屏夹角为预设角度5(例如10°)至180°之间时，霍尔传感器可以确定电子设备的设备形态为远离态。
在内屏夹角为预设角度6(例如5°)至预设角度5(例如10°)之间时，电子设备的设备形态也可以被称为跟随态3。该跟随态3用于表示：如果前一帧为接近态，内屏夹角在预设角度6(例如5°)至预设角度5(例如10°)之间时，霍尔传感器获取的当前帧也为接近态。即可以理解为，如图4中(2)所示，在电子设备的初始状态为闭合，展开电子设备时，内屏夹角在预设角度6(例如5°)至预设角度5(例如10°)之间时，霍尔传感器可以确定电子设备的设备形态为接近态。如果前一帧为远离态，内屏夹角在预设角度6(例如5°)至预设角度5(例如10°)之间时，霍尔传感器获取的当前帧也为远离态。 即可以理解为，如图4中(3)所示，在电子设备的初始状态为展开，闭合电子设备时，内屏夹角在预设角度6(例如5°)至预设角度5(例如10°)之间时，霍尔传感器可以确定电子设备的设备形态为远离态。
在一些可能的情况下，电子设备可以将上报后的接近态映射为折叠态，将上报后的远离态映射成为展开态(半展开态或者全展开态)。
霍尔传感器上报设备形态的时机包括：启动后的第一帧(一帧就是一个设备形态)，从第二帧开始，在检测到电子设备的设备形态相比于前一帧发生变化时可以上报。
例如，如图4中(2)所示，黑色三角形符号所在的位置可以是霍尔传感器上报霍尔事件的示例性时机。在闭合时展开电子设备的情况下，内屏夹角从小于预设角度5变化到大于预设角度5的过程中，电子设备的设备形态从接近态变化到远离态，则霍尔传感器可以上报一帧设备形态(此时为远离态)。
再例如，如图4中(3)所示，黑色三角形符号所在的位置可以是霍尔传感器上报霍尔事件的示例性时机。在展开时闭合电子设备的情况下，内屏夹角从大于预设角度6变化到小于预设角度6的过程中，电子设备的设备形态从远离态变化到接近态，则霍尔传感器可以上报一帧设备形态(此时为接近态)。
本申请实施例中，按照预设规则，霍尔传感器以及姿态传感器可以获取设备形态并上报，电子设备可以基于霍尔传感器以及姿态传感器上报的设备形态进行融合，以确定电子设备最终的设备形态。在闭合电子设备的过程中，在电子设备的设备形态从展开态切换为折叠态的情况下，使得内屏熄灭，且外屏点亮。展开电子设备的过程中，在电子设备的设备形态从折叠态切换为展开态的情况下，使得外屏熄灭，且内屏点亮。其中，预设规则包括但不限于以下规则：
预设规则1：以姿态传感器为主，霍尔传感器为辅助。具体包括：电子设备在灭屏(内屏和外屏均熄灭)时，关闭姿态传感器。在非灭屏(内屏点亮和/或外屏点亮)时，开启姿态传感器。无论灭屏，还是非灭屏，电子设备在开机之后均开启霍尔传感器，但是，在非灭屏时，对于霍尔传感器上报的霍尔事件不进行处理，电子设备基于姿态传感器最近一次上报的姿态事件确定电子设备的设备形态，基于设备形态控制亮屏。在灭屏时，电子设备基于霍尔传感器上报的霍尔事件确定电子设备的设备形态，基于设备形态控制亮屏。灭屏时，电子设备可以不通过姿态传感器获取姿态事件。
该预设规则1中还包括一种特殊情况(特殊情况1)：电子设备的初始状态为闭合且灭屏时，展开电子设备到内屏夹角大于或者等于预设角度5(例如10°)时，霍尔传感器可以确定电子设备的设备形态为远离态，并将该远离态进行上报，电子设备基于该远离态确定电子设备的设备形态为展开态，触发内屏点亮，且保持外屏熄灭。内屏点亮之后，姿态传感器开启，进而姿态传感器可以获取姿态事件并上报。在预设角度5(例如10°)至预设角度3(例如45°)之间，姿态传感器可以上报首帧(第一帧)姿态事件(姿态事件A)。其中，在该姿态事件A为一帧折叠态时，与霍尔传感器上报的远离态所映射的展开态冲突。针对该特殊情况2，电子设备处理该冲突的方式可以包括：特殊情况1时，在姿态传感器上报该姿态事件A之后的预设时间T(例如1s)内，电子设备不基于该姿态事件 进行处理。
预设规则2：姿态传感器和霍尔传感器同等重要。具体包括：电子设备在灭屏(内屏和外屏均熄灭)时，关闭姿态传感器。在非灭屏(内屏点亮和/或外屏点亮)时，开启姿态传感器。电子设备在开机之后均开启霍尔传感器。姿态传感器上报姿态事件时，电子设备在闭合以及展开时可以基于该姿态事件确定电子设备的设备形态，基于设备形态控制亮屏。霍尔传感器上报霍尔事件时，电子设备在闭合以及展开时可以基于该霍尔事件确定电子设备的设备形态，基于设备形态控制亮屏。
该预设规则2中还包括一种特殊情况(特殊情况2)：电子设备的初始状态为闭合且灭屏时，展开电子设备到内屏夹角大于或者等于预设角度5(例如10°)时，霍尔传感器可以确定电子设备的设备形态为远离态，并将该远离态进行上报，电子设备基于该远离态确定电子设备的设备形态为展开态，触发内屏点亮，且保持外屏熄灭。内屏点亮之后，姿态传感器开启可以获取姿态事件并上报。在预设角度5(例如10°)至预设角度3(例如45°)之间，姿态传感器可以获取首帧姿态事件(姿态事件B)。其中，在该姿态事件B为一帧折叠态时，与霍尔传感器上报的远离态所映射的展开态冲突。针对该特殊情况2，电子设备处理该冲突的方式包括但不限于以下方式。
方式1:特殊情况2中，在姿态传感器确定该姿态事件B为折叠态之后，可以不将该姿态事件B进行上报，则电子设备可以不基于该姿态事件B控制屏幕亮屏。这样，可以避免以下问题1：在内屏夹角展开到预设角度5(例如10°)时，电子设备触发内屏点亮且外屏熄灭之后，又在预设角度5(例如10°)至预设角度3(例如45°)之间，基于折叠态触发电子设备将内屏熄灭，外屏点亮。使得用户在短时间内看见切屏，但是用户本意是展开电子设备，则内屏熄灭，外屏点亮不符合用户预期。其中，切屏指的是在其中非灭屏情况下，基于设备形态控制亮屏。例如，在内屏点亮，外屏熄灭的情况下，闭合电子设备到设备形态为折叠态时，控制内屏熄灭，外屏点亮的操作可以称为切屏。再例如，在内屏熄灭，外屏点亮的情况下，展开电子设备到设备形态为展开态时，控制内屏点亮，外屏熄灭的操作可以称为切屏。
方式2：特殊情况2中，在姿态传感器确定该姿态事件B为折叠态之后，在确定该折叠态下内屏夹角小于预设角度7(例如4°)的情况下，该姿态传感器可以将该姿态事件B上报，电子设备可以基于该姿态事件B确定电子设备的设备形态，基于设备形态控制亮屏(内屏熄灭，外屏点亮)。在确定该折叠态下内屏夹角大于或者等于预设角度7(例如4°)的情况下，可以不将该姿态事件B进行上报，则电子设备可以不基于该姿态事件B控制屏幕亮屏。其中，预设角度7小于或者等于预设角度5(例如5°)。这样不仅可以解决前述涉及的问题1。还可以解决问题2：在霍尔传感器失效时，误报现在是远离态(其实是接近态，用户也许并不期望展开电子设备)，使得电子设备触发内屏点亮，外屏熄灭之后，可以及时使得基于姿态传感器上报的折叠态触发内屏熄灭，外屏点亮。其中，预设角度7(例如4°)是基于姿态传感器获取的。
基于前述涉及的预设规则1以及预设规则2，相比于只使用霍尔传感器控制亮屏的方 案，在一些场景下，本申请实施例中电子设备可以实现更合理的控制亮屏。
在一些可能的情况下，本申请涉及的在电子设备展开或者折叠时合理亮屏包括但不限于以下几个场景。
场景1：电子设备的初始状态为闭合，且，内屏以及外屏均熄灭的情况下，展开电子设备(从折叠态到展开态)时，尽快(例如展开到10°)触发内屏点亮且外屏熄灭。该场景1可以通过以下方式实现：场景1中，内屏以及外屏均熄灭的情况下，闭合时展开电子设备到内屏夹角大于或者等于预设角度5(例如10°)时，霍尔传感器可以确定电子设备的设备形态为远离态，并将该远离态进行上报，电子设备基于该远离态确定电子设备的设备形态为展开态，触发内屏点亮，且保持外屏熄灭。
场景2：电子设备的初始状态为展开，且，内屏或者外屏点亮的情况下，闭合电子设备(从展开态到折叠态)时，尽快(折叠到大于10°，例如40°)触发内屏熄灭且外屏点亮。该场景2可以通过以下方式实现：场景2中，内屏或者外屏点亮的情况下，姿态传感器开启。展开闭合电子设备到内屏夹角小于或者等于预设角度2(例如40°)时，姿态传感器可以确定电子设备的设备形态为折叠态，并将该折叠态进行上报，电子设备基于该折叠态触发内屏熄灭且外屏点亮。相比于在场景2中使用霍尔传感器检测电子设备形态变化的方案，可以提前35°(40°减5°)左右检测到电子设备处于折叠态了，进而可以提前35°触发内屏熄灭且外屏点亮。这样，更符合用户闭合电子设备时，希望内屏点亮，外屏熄灭的预期。
图5示出了电子设备控制亮屏时涉及的一种实例性软件结构框图。
下面结合图5描述电子设备基于霍尔传感器以及姿态传感器上报的设备形态控制亮屏时，部分模块交互的过程。
如图5所示，软件结构中包括至少一个子***。例如可以包括应用程序子***以及***控制子***。不同的子***可以被分成若干个层，每一层都有清晰的角色和分工。层与层之间通过软件接口通信。
在一些实施例中，将应用程序子***中可以包括应用程序层，应用程序框架层，硬件抽象层，以及内核层。***控制子***中可以包括框架层、内核层。为了便于区分，可以将***控制子***中的框架层称为协框架层、将***控制子***中的内核层称为协内核层。应该理解的是，实际应用中，除了图5中示出的层级以外，该应用程序子***以及***控制子***中还可以包括更多或者更少的层级。本申请实施例对此不作限定。
其中，应用程序子***中的应用程序层可以包括一系列应用程序包。例如，可以包括相机、日历、WLAN、音乐、图库、通话、导航以及蓝牙等应用程序包。
应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。
应用程序子***中的应用程序框架层可以包括***服务器。该***服务器中可以包括屏幕管理模块、设备状态管理服务器、传感器服务等。
其中，屏幕管理模块中可以包括电源管理服务器、窗口管理服务器等。屏幕管理模块中的各个模块可以用于接收设备状态管理服务器发送的点亮屏幕的通知，该通知用于触发 屏幕管理模块启动亮屏流程。在一些可能的情况下，电源管理服务器可以用于控制屏幕的上电与下电。窗口管理服务器可以用于绘制显示窗口，在屏幕上电之后，将显示窗口置于屏幕中供用户查看。
设备状态管理服务器在向传感器服务注册姿态传感器以及霍尔传感器之后，即可以用于接收姿态传感器上报的姿态事件，以及霍尔传感器上报的霍尔事件。然后基于姿态事件以及霍尔事件确定电子设备最终的设备形态。基于该设备形态作出控制亮屏的决策，触发屏幕管理模块启动亮屏流程。
传感器服务可以用于将接收到的姿态事件以及霍尔事件上报至设备状态管理服务器。
硬件抽象层是位于内核层与硬件层(未示出)之间的接口层，其目的在于将硬件抽象化，为操作***提供虚拟硬件平台。
硬件抽象层中可以包括传感器接口服务、核间通信模块A等。
其中，传感器接口服务可以用于注册各传感器，在注册之后接收各传感器发送的数据。例如，该传感器接口服务中可以包括姿态传感器接口以及霍尔传感器接口。其中，姿态传感器接口可以用于管理注册姿态传感器，以及接收姿态传感器上传的姿态事件，并且，将该姿态事件发送至传感器服务。霍尔传感器接口可以用于管理注册霍尔传感器，以及接收霍尔传感器上传的霍尔事件，并且，将该霍尔事件发送至传感器服务。
核间通信模块A可以用于管理应用程序子***与***控制子***间的通信。使得***控制子***以及应用程序子***可以相互传输数据。例如接收***控制子***传输的姿态事件、霍尔事件等。
***控制子***中的协框架层中可以包括事件分发管理器、传感器客户端管理器、核间通信模块B等。
其中，事件分发管理器可以用于接收下述协内核层上传的数据，并将其分发给其他已向该事件分发管理器注册的模块。例如，该事件分发管理器可以用于接收姿态传感器上报的姿态事件，然后将该姿态事件传输至传感器客户端管理器。该事件分发管理器还可以用于接收霍尔传感器上报的霍尔事件，然后将该霍尔事件传输至传感器客户端管理器。
传感器客户端管理器可以用于向事件分发管理器注册之后，获取事件分发管理器上传的数据，例如包括姿态事件以及霍尔事件等。
核间通信模块B可以用于管理应用程序子***与***控制子***间的通信。使得***控制子***以及应用程序子***可以相互传输数据。例如，核间通信模块B可以用于接收传感器客户端管理器传输的姿态事件、霍尔事件等，并将该姿态事件、霍尔事件等数据传输至核间通信模块A。
传感器驱动可以用于启动传感器，例如可以启动姿态传感器、霍尔传感器等。姿态传感器在启动之后，可以获取姿态事件，并将该姿态事件进行上报。例如，在将第一帧姿态事件上报至事件分发管理器。后续，如果当前帧姿态事件与前一帧姿态事件不同，也可以将当前帧姿态事件上报至事件分发管理器。霍尔传感器在启动之后，可以获取霍尔事件，并将该霍尔事件进行上报。例如，在将第一帧霍尔事件上报至事件分发管理器。后续，如果当前帧霍尔事件与前一帧霍尔事件不同，也可以将当前帧霍尔事件上报至事件分发管理器。
在一些可能的情况下，姿态传感器以及霍尔传感器上报数据还可以包括：姿态传感器以及霍尔传感器可以分别将姿态事件以及霍尔事件经过图5中步骤1-步骤4的传输路径(即白色圆圈1-白色圆圈4指示的路径)，将姿态事件和霍尔事件上报至设备状态管理服务器。然后，设备状态管理服务器执行步骤5(图中白色圆圈5)：基于姿态事件以及霍尔事件确定电子设备最终的设备形态，然后基于该设备形态作出控制亮屏的决策，触发屏幕管理模块启动亮屏流程。
应该理解的是，图5示出的是电子设备的一种示例性软件框图，不应该构成对本申请实施例的限定。例如，各个模块的位置(例如所属层级)在实际应用中可以不同。这里以姿态传感器为例进行说明，在姿态传感器为基于软件算法的虚拟传感器时，姿态传感器可以在应用程序子***侧运行，也可以在***控制子***侧运行。其中，该***控制子***也可以被称为协处理器子***。
在一些可能的实施例(实施例1)中，电子设备可以按照前述涉及的预设规则1，通过霍尔传感器以及姿态传感器确定电子设备的设备形态变化，进而基于设备形态实现合理亮屏。在该实施例中，以姿态传感器为主，霍尔传感器为辅助：除前述涉及的特殊情况1外，在该实施例中，非灭屏(内屏点亮和/或外屏点亮)时，以姿态传感器上报的姿态事件确定电子设备的设备形态。在灭屏(内屏和外屏均熄灭)时，以霍尔传感器上报的姿态事件确定电子设备的设备形态。特殊情况1包括：闭合(灭屏)时展开电子设备的情况下，在电子设备展开到内屏夹角大于或者等于预设角度5(例如10°)时，基于霍尔传感器点亮内屏，然后启动姿态传感器，但是在姿态传感器上报的首帧姿态事件为折叠态时，在预设时间T(例如1s)内，电子设备不基于该首帧姿态事件进行处理。达到预设时间T之后，再基于姿态传感器最近一次上报的姿态事件确定电子设备的设备形态。
该实施例中，电子设备在灭屏(内屏和外屏均熄灭)时，关闭姿态传感器。在非灭屏(内屏点亮和/或外屏点亮)时，开启姿态传感器。电子设备在开机之后均开启霍尔传感器。
关于预设规则1的详细描述可以参考前述内容，此处不再赘述。
图6A-图6D示出了按照预设规则1控制亮屏的示意图。
图6A-图6D中，“全展开切半展开”角度(例如145°)可以看作一种预设角度1。“展开切折叠”角度(例如40°)可以看作一种预设角度2。“折叠切展开”角度(例如45°)可以看作一种预设角度3。“半展开切全展开”角度(例如150°)可以看作一种预设角度4。“接近切远离”角度(例如10°)可以看作一种预设角度5。“远离切接近”角度(例如5°)可以看作一种预设角度6。
下面结合图6A-图6D对实施例1中，针对不同情况下控制亮屏的相关内容进行示例性描述。具体从以下几种情况进行描述。
情况11：初始状态为闭合且灭屏，在闭合(灭屏)时展开电子设备。其中，电子设备初始状态为闭合包括：电子设备在展开之前，内屏夹角小于“接近切远离”角度(例如10°)，例如，内屏夹角接近0°或者等于0°。灭屏是指电子设备的内屏和外屏均熄灭。
如图6A所示，该情况11中，电子设备的初始状态为灭屏，则姿态传感器未开启，故姿态传感器不工作。此时，展开电子设备的过程中，涉及的首个设备形态是基于霍尔传感 器确定的。例如，参考图6A中的霍尔工作轴可知：展开电子设备的过程中，在内屏夹角为0°至“接近切远离”角度之间的角度时，霍尔传感器可以获取电子设备的设备形态(此时为接近态)。
后续，继续展开电子设备，在内屏夹角达到(大于或者等于)“接近切远离”角度处(例如，霍尔工作轴中的黑色三角形处)，霍尔传感器可以确定电子设备的设备形态为远离态，并将该远离态作为霍尔事件上报。然后，电子设备将该远离态映射成为展开态，则触发内屏点亮且外屏熄灭。此时，电子设备还可以开启姿态传感器。参考姿态工作轴，姿态传感器在内屏夹角达至“接近切远离”角度之后开启。在内屏夹角处于“接近切远离”角度至“折叠切展开”角度的过程中，姿态传感器获取的姿态事件为折叠态，与霍尔传感器上报的远离态所映射的展开态矛盾。因此，也可以称内屏夹角处于“接近切远离”角度至“折叠切展开”角度之间的角度为冲突区域(冲突区域1)。电子设备展开到内屏夹角处于冲突区域1时，如果姿态传感器上报姿态事件(姿态事件A)，此时，该姿态事件A为折叠态，则电子设备可以在预设时间T内不基于该姿态事件A进行处理。达到预设时间T之后，再基于姿态传感器最近一次上报的姿态事件确定电子设备的设备形态。其中，姿态传感器上报姿态事件A的一个示例性位置可以为姿态工作轴中白色正方形处。
其中，该最近一次上报的姿态事件包括可以下几种结果，不同结果下电子设备控制亮屏的方式不同。具体可以参考以下描述：
结果11：该最近一次上报的姿态事件仍然为姿态事件A，则电子设备基于该姿态事件A确定电子设备为折叠态，则可以触发内屏熄灭，外屏点亮。在该结果11中，展开电子设备的过程中，电子设备在内屏夹角展开到大于或者等于“接近切远离”角度(例如10°)处触发内屏点亮之后，在展开至“折叠切展开”角度(例如45°)处又切换到外屏点亮。存在不符合用户预期的可能性，后续涉及的预设规则2中可以避免该结果11的产生，具体可以参考下述相关内容的描述，此处暂不赘述。
结果12：该最近一次上报的姿态事件不为姿态事件A，可以为其他姿态事件，该其他姿态事件可以为展开态(包括半展开态以及全展开态)。例如，在内屏夹角展开到大于或者等于“折叠切展开”角度(例如45°)时，姿态传感器上报的其他姿态事件可以为半展开态。其中一个上报该其他姿态事件的一个示例性位置可以为姿态工作轴中黑色三角形处。再例如，在内屏夹角展开到大于或者等于“半展开切全展开”角度(例如150°)时，姿态传感器上报的其他姿态事件可以为全展开态。其中一个上报该其他姿态事件的一个示例性位置可以为姿态工作轴中白色三角形处。在该结果12中，在展开电子设备的过程中，电子设备在内屏夹角展开到大于或者等于“接近切远离”角度(例如10°)处触发内屏点亮之后，不会在继续展开电子设备的过程中触发切换到外屏点亮，符合用户期望。
关于情况11中电子设备控制屏幕亮屏涉及的流程可以参考下述对图7的描述，此处不再赘述。
情况12：初始状态为闭合(非灭屏)，在闭合(非灭屏)时展开电子设备。其中，电子设备初始状态为闭合包括：电子设备在展开之前，内屏夹角小于“接近切远离”角度(例如10°)，例如，内屏夹角接近0°或者等于0°。非灭屏是指电子设备的内屏以及外屏 中至少一个点亮。
如图6B所示，该情况12中，电子设备的初始状态为非灭屏，则姿态传感器开启，以姿态传感器上报的姿态事件确定电子设备的设备形态。姿态传感器开启时，电子设备不基于霍尔传感器上报的霍尔事件进行处理(因此图6B中霍尔工作轴用虚线表示)。此时，参考姿态工作轴，展开电子设备时，在内屏夹角展开到大于或者等于“折叠切展开”角度(例如45°)时，姿态传感器可以上报一帧半展开态，电子设备基于该半展开态使得内屏点亮，外屏熄灭。其中一个上报半展开态的示例性位置可以为姿态工作轴中黑色三角形处。后续，继续展开电子设备时，在内屏夹角展开到大于或者等于“半展开切全展开”角度(例如150°)时，姿态传感器可以上报一帧全展开态，电子设备基于该全展开态保持内屏点亮，外屏熄灭。其中一个上报全展开态的示例性位置可以为姿态工作轴中白色三角形处。
关于情况12中电子设备控制屏幕亮屏涉及的流程可以参考下述对图8的描述，此处不再赘述。
情况13：初始状态为展开(非灭屏)，在展开(非灭屏)时闭合电子设备。其中，电子设备初始状态为展开包括：电子设备在闭合之前，电子设备的设备形态为展开态，通常来说大于“展开切折叠”角度，例如，内屏夹角为180°或者接近180度时，可以为展开态。非灭屏是指电子设备的内屏以及外屏中至少一个点亮。
如图6C所示，该情况13中，电子设备的初始状态为非灭屏，则姿态传感器开启，以姿态传感器上报的姿态事件确定电子设备的设备形态。姿态传感器开启时，电子设备不基于霍尔传感器上报的霍尔事件进行处理(因此图6C中霍尔工作轴用虚线表示)。此时，参考姿态工作轴，闭合电子设备时，在内屏夹角闭合到小于或者等于“全展开切半展开”角度(例如145°)时，姿态传感器可以上报一帧半展开态，电子设备基于该半展开态确定电子设备仍然处于展开态。其中一个上报全展开态的示例性位置可以为姿态工作轴中黑色三角形处。后续，继续闭合电子设备时，在内屏夹角闭合到小于或者等于“展开切折叠”角度(例如40°)时，姿态传感器可以上报一帧折叠态，电子设备基于该折叠态使得内屏熄灭，外屏点亮。其中一个上报折叠态的示例性位置可以为姿态工作轴中白色三角形处。
应该理解的是，参考图6B以及图6C，“折叠切展开”角度(例如45°)与“展开切折叠”角度(例如40°)之间应当尽量接近，两者之差通常不大于10°，例如可以为5°。这样可以保证在非灭屏时展开电子设备以及非灭屏时闭合电子设备时，电子设备可以通过姿态传感器在接近的内屏夹角处获取到相同的设备形态，便于其他功能的实施。
情况14：初始状态为展开(灭屏)，在展开(灭屏)时闭合电子设备。其中，电子设备初始状态为展开包括：电子设备在闭合之前，电子设备的设备形态为展开态，通常来说大于45°，例如，内屏夹角为180°或者接近180度时，可以为展开态。灭屏是指电子设备的内屏以及外屏均熄灭。
如图6D中所示，该情况14中，电子设备的初始状态为灭屏，则姿态传感器未开启，故姿态传感器不工作。因此，闭合电子设备的过程中，涉及的首个设备形态是基于霍尔传感器确定的。例如，参考图6D中的霍尔工作轴可知：在内屏夹角为180°至“远离切接近” 角度之间的角度时，霍尔传感器可以获取电子设备的设备形态(此时为远离态)，但是不上报该远离态。后续闭合电子设备到内屏夹角小于或者等于“远离切接近”角度时，霍尔传感器可以获取电子设备的设备形态(此时为接近态)，并将该接近态上报。然后，电子设备将该接近态映射成为折叠态，保持内屏以及外屏熄灭。在内屏和外屏均熄灭的情况下，响应于针对亮屏的操作，电子设备可以实现亮屏。并且在亮屏之后，开启姿态传感器。其中，亮屏的操作包括针对电源键的操作，解锁操作等。
在另一些可能的情况下，情况14中，在内屏夹角闭合到小于或者等于“远离切接近”角度(例如5°)的情况下，霍尔传感器上报霍尔事件。此时，该霍尔事件为接近态，电子设备将该接近态映射成为折叠态后，还可以触发外屏点亮，保持内屏熄灭。且，电子设备还可以开启姿态传感器。姿态传感器在开启之后，上报首帧姿态事件的位置可以为图中白色正方形所在的位置。该首帧姿态事件为折叠态，与霍尔传感器上报的接近态折叠后的设备状态相同，电子设备保持内屏熄灭且外屏点亮。其中，霍尔传感器上报折叠态的位置可以为图中黑色三角形所在位置。
图7示出了情况11中电子设备控制屏幕亮屏时，各个模块间的交互流程。
下面结合图7详细描述初始状态为闭合(灭屏)，展开电子设备时控制屏幕亮屏的过程。该过程涉及的主要模块包括霍尔传感器、姿态传感器、传感器服务、设备状态管理服务器、屏幕管理模块。该过程可以参考下述对步骤S11-步骤S21b的描述。
S11.霍尔传感器获取霍尔事件，该霍尔事件包括接近态、远离态等设备形态中的一个，在检测到设备形态发生变化的情况下，向传感器服务上报霍尔事件，其中，接近态可以被映射为折叠态，远离态可以被映射为展开态。

S13.将霍尔事件上报至设备状态管理服务器，以使得设备状态管理服务器确定设备形态为展开态。
S14a.设备状态管理服务器通知屏幕管理模块控制内屏点亮。
这样，如图6A所示，在电子设备展开至“接近切远离”角度(例如10°)时，屏幕管理模块可以通过电源管理服务器、窗口管理服务器等模块控制内屏点亮，此时外屏仍然保持熄灭。其中，展开至“接近切远离”角度(例如10°)的位置可以参考霍尔工作轴中黑色三角形所在的位置处。
S14b.设备状态管理服务器向传感器服务发起注册姿态传感器的请求。
这里应该理解的是，步骤S14a以及步骤S14b可以为设备状态管理服务器确定设备形态为展开态之后出发的操作。该步骤S14a以及步骤S14b的执行顺序没有先后之分。通常来说，可以并发执行。
S15.传感器服务器通知启动姿态传感器。

在该姿态事件为上传的首帧姿态事件的情况下，执行下述步骤S20b。
S20a.设备状态管理服务器基于该姿态事件通知屏幕管理模块控制屏幕亮屏。
在该姿态事件为折叠态的情况下，设备状态管理服务器可以控制切屏：触发内屏熄灭，外屏点亮。该情况涉及的一种示例可以参考前述对结果11的描述：此时该姿态事件为折叠态且为首帧姿态事件，这表示用户展开电子设备的速度较慢，因此在内屏点亮之后，又触发了内屏熄灭，外屏点亮。该情况涉及的另一种示例包括：用户展开电子设备到内屏夹角大于或者等于“折叠切展开”角度(例如45°)之后，又开始闭合电子设备到内屏夹角小于或者等于“展开切折叠”角度(例如40°)。
在该姿态事件为展开态的情况下，表示姿态传感器与霍尔传感器上报的事件不冲突。设备状态管理服务器可以不对该姿态事件进行处理，继续保持内屏点亮，外屏熄灭。该情况可以参考前述对结果12的描述。
S20b.设备状态管理服务器确定该姿态事件是否为折叠态。
在该姿态事件不为折叠态的情况下，执行下述步骤S21a。

图8示出了情况12中电子设备控制屏幕亮屏时，各个模块间的交互流程。
下面结合图8详细描述初始状态为闭合(非灭屏)，展开电子设备时控制屏幕亮屏的过程。该过程涉及的主要模块包括姿态传感器、传感器服务、设备状态管理服务器、屏幕管理模块。其中，步骤S30a、步骤S31a、步骤S32a、步骤S33a置于虚线框中，表示在非灭屏的情况下，姿态传感器开启，则虽然霍尔传感器会上报霍尔事件，但是设备状态管理服务器不会基于该霍尔事件进行处理。该过程可以参考下述对步骤S30a-步骤S33b的描述。
S30a.霍尔传感器获取霍尔事件，该霍尔事件包括接近态、远离态等设备形态中的一个，在检测到设备形态发生变化的情况下，向传感器服务上报霍尔事件。

S32b.将姿态事件上报至设备状态管理服务器，以使得设备状态管理服务器确定设备形态为展开态。
S33b.通知屏幕管理模块控制切屏，使得内屏点亮，外屏熄灭。
应该理解的是，情况13中电子设备控制屏幕亮屏时，各个模块间的交互流程与情况12中电子设备控制屏幕亮屏时，各个模块间的交互流程相似，不同之处在于姿态传感器上报姿态事件的时机不同。可以参考前述对图8中相关内容的描述，此处不再赘述。情况14中电子设备控制屏幕亮屏时，各个模块间的交互流程与情况12中电子设备控制屏幕亮屏时，各个模块间的交互流程相似，不同之处在于灭屏时，姿态传感器未开启，则关于姿态传感器的内容不涉及。且情况14中可以基于霍尔传感器上报的霍尔事件确定设备形态，其他相同之处可以参考前述对图8中相关内容的描述，此处不再赘述。
在另一些可能的实施例(实施例2)中，电子设备可以按照预设规则2，通过霍尔传感器以及姿态传感器确定电子设备的设备形态变化，进而基于设备形态实现合理亮屏。在该实施例中，姿态传感器与霍尔传感器不分主次，同等重要：除前述涉及的特殊情况2外，在该实施例中姿态传感器上报姿态事件时，电子设备可以基于该姿态事件确定电子设备的设备形态，基于设备形态控制亮屏。霍尔传感器上报霍尔事件时，电子设备可以基于该霍尔事件确定电子设备的设备形态，基于设备形态控制亮屏。特殊情况2包括：闭合(灭屏)时展开电子设备的情况下，在电子设备展开到大于或者等于预设角度5(例如10°)时，基于霍尔传感器点亮内屏，然后启动姿态传感器，但是在姿态传感器获取的首帧姿态事件为折叠态时，可以不将该姿态事件进行上报，这样，电子设备可以保持内屏点亮，外屏熄灭。或者，在该首帧姿态事件为折叠态以及确定内屏夹角小于预设角度7(例如4°)时，可以将该姿态事件进行上报，这样，电子设备可以在霍尔传感器误报远离态(实际为接近态)时更正到外屏点亮，内屏熄灭。
该实施例中，电子设备在灭屏(内屏和外屏均熄灭)时，关闭姿态传感器。在非灭屏(内屏点亮和/或外屏点亮)时，开启姿态传感器。电子设备在开机之后均开启霍尔传感器。
关于预设规则2的详细描述可以参考前述内容，此处不再赘述。
图9A以及图9B示出了按照预设规则2控制亮屏的示意图。
图9A以及图9B中，“全展开切半展开”角度(例如145°)可以看作一种预设角度 1。“展开切折叠角度+补充角度2”(例如60°)可以看作一种预设角度2。“折叠切展开角度+补充角度1”(例如65°)可以看作一种预设角度3。“半展开切全展开”角度(例如150°)可以看作一种预设角度4。“接近切远离”角度(例如10°)可以看作一种预设角度5。“远离切接近”角度(例如5°)可以看作一种预设角度6。
其中，“折叠切展开角度+补充角度1”是前述实施例1中涉及的“折叠切展开”角度与补充角度1的和。“展开切折叠角度+补充角度2”是前述实施例1中涉及的“展开切折叠”角度与补充角度2的和。补充角度1和补充角度2可以为大于0的角度，例如20°、30°，可以根据实际需求进行调整，本申请实施例对此不作限定。
这里应该理解的是，实施例2涉及的预设角度3相比于实施例1中涉及的预设角度3相比更大(相差一个补充角度1)。其原因在于，实施例1中，由于非灭屏时，霍尔传感器上报的远离态会被忽略，需继续展开至“折叠切展开”角度(例如45°)时，才可以基于姿态传感器上报的半展开态触发内屏点亮，外屏熄灭。因此，“折叠切展开”角度通常不宜过大，否则会影响闭合时展开电子设备的亮屏合理性。同时，该“折叠切展开”角度也不宜太小，否则影响展开(非灭屏)时闭合电子设备的亮屏合理性。因为展开(非灭屏)时闭合电子设备的过程中，在闭合电子设备到内屏夹角达至“展开切折叠”角度(例如40°)时，才可以触发内屏熄灭，外屏点亮。“折叠切展开”角度(例如45°)与“折叠切展开”角度(例如40°)之间应当尽量接近，这样才可以保证在非灭屏时展开电子设备以及非灭屏时闭合电子设备时，电子设备可以通过姿态传感器在接近的内屏夹角处获取到相同的设备形态，便于其他功能的实施。因此，可以将该“折叠切展开”角度取到45°左右。但是，在该实施例2中，在闭合且非灭屏，然后展开电子设备的情况下，在展开电子设备到内屏夹角达至“接近切远离”角度(例如10°)时，实施2中即可基于霍尔传感器上报的远离态触发内屏点亮，外屏熄灭。不需要基于姿态传感器上报的半展开态触发内屏点亮，外屏熄灭。因此在该实施例2中的预设角度3(“折叠切展开角度+补充角度1”)可以设置的比实施1的预设角度3(“折叠切展开”角度)更大。由于预设角度2与预设角度3应当尽量接近，则实施例2中的预设角度2相比于实施1中的预设角度2(例如“展开切折叠”角度)也可以更大，例如可以将实施例2中的预设角度2设置为“展开切折叠角度+补充角度2”，该补充角度2与补充角度1大小接近，通常来说补充角度2可以与补充角度1相同。其中，该补充角度1可以取值为大于0的角度，例如20°、30°等，本申请实施例对此不作限定。
下面结合图9A以及图9B对实施例2中，针对不同情况下控制亮屏的相关内容进行示例性描述。具体从以下几种情况进行描述。
情况21：初始状态为闭合(灭屏或非灭屏)，在闭合(灭屏或非灭屏)时展开电子设备。其中，电子设备初始状态为闭合包括：电子设备在展开之前，内屏夹角小于“接近切远离”角度(例如10°)，例如，内屏夹角接近0°或者等于0°。无论闭合时屏幕的状态如何，展开电子设备时都可以在内屏夹角达至“接近切远离”角度(例如10°)时使得内屏点亮、外屏熄灭。
应该理解的是，初始状态为闭合(灭屏或非灭屏)，展开电子设备到内屏夹角达至“接近切远离”角度(例如10°)时使得内屏点亮、外屏熄灭。涉及的内容包括但不限于以下 内容中的部分或者全部：
内容11：初始状态为闭合，且内屏以及外屏均熄灭的情况下，展开电子设备到内屏夹角达至“接近切远离”角度(例如10°)时，触发内屏点亮，保持外屏熄灭。
内容12：初始状态为闭合，且内屏熄灭、外屏点亮的情况下，展开电子设备到内屏夹角达至“接近切远离”角度(例如10°)时，触发内屏点亮，外屏熄灭。
内容13：初始状态为闭合，且内屏点亮、外屏均熄灭的情况下，展开电子设备到内屏夹角达至“接近切远离”角度(例如10°)时，保持内屏点亮，外屏熄灭。
内容14：初始状态为闭合，且内屏以及外屏均点亮的情况下，展开电子设备到内屏夹角达至“接近切远离”角度(例如10°)时，保持内屏点亮，触发外屏熄灭。在一些实施例中，闭合时内屏熄灭。
如图9A所示，电子设备的初始状态为闭合(灭屏或者非灭屏)，无论姿态传感器在灭屏时不工作，还是在非灭屏时工作的情况下，当展开电子设备到内屏夹角达至“接近切远离”角度(例如10°)时，电子设备均可以将霍尔传感器上报远离态映射成为展开态，使得内屏点亮、外屏熄灭。
参考图9A的霍尔工作轴可知：灭屏或者非灭屏时展开电子设备的过程中，在内屏夹角为0°至“接近切远离”角度之间的角度时，霍尔传感器可以获取电子设备的设备形态(此时为接近态)。后续，继续展开电子设备，在内屏夹角达到(大于或者等于)“接近切远离”角度处(例如，霍尔工作轴中的黑色三角形处)，霍尔传感器可以确定电子设备的设备形态为远离态，并将该远离态作为霍尔事件上报。电子设备将该霍尔事件(远离态)映射成为展开态，触发内屏点亮，保持外屏熄灭。其中，霍尔传感器上报该霍尔事件(远离态)的一个示例性位置可以为霍尔工作轴中黑色三角形处。此时，如果初始状态为闭合且灭屏，触发内屏点亮，保持外屏熄灭的情况下，还可以开启姿态传感器。参考姿态工作轴，姿态传感器在内屏夹角达至“接近切远离”角度之后开启。在内屏夹角处于“接近切远离”角度至“折叠切展开角度+补充角度1”的过程中，姿态传感器获取的姿态事件为折叠态，与霍尔传感器上报的远离态所映射的展开态矛盾。因此，也可以称内屏夹角处于“接近切远离”角度至“折叠切展开角度+补充角度1”之间的角度为冲突区域(冲突区域2)。电子设备展开到内屏夹角处于冲突区域2时，姿态传感器可以获取首帧姿态事件(姿态事件B)。
此时，如果该姿态事件B为半展开态或者展开态，则姿态传感器可以将该姿态事件B进行上报。电子设备可以不对该姿态事件B(半展开态或者展开态)进行处理，仍然保持内屏点亮，外屏熄灭。其中，姿态传感器上报半展开态的一个示例性位置可以为姿态工作轴中黑色三角形处。姿态传感器上报全展开态的一个示例性位置可以为姿态工作轴中白色三角形处，例如在内屏夹角展开至“半展开切全展开”角度时。
如果该姿态事件B为折叠态，则与霍尔传感器上报的远离态所映射的展开态冲突。电子设备处理该冲突的方式可以包括前述涉及的方式1以及方式2。
方式1：在姿态传感器确定该姿态事件B为折叠态之后，可以不将该姿态事件B进行上报，则电子设备可以不基于该姿态事件B控制屏幕亮屏。仍然保持内屏点亮，外屏熄灭。关于该方式1的详细描述可以参考前述对方式1的描述，此处不再赘述。其中，姿态传感 器获取姿态事件B但是不上报的一个示例性位置可以为姿态工作轴中白色正方形处。
方式2：在姿态传感器确定该姿态事件B为折叠态之后，在确定该折叠态下内屏夹角小于预设角度7(例如4°)的情况下，该姿态传感器可以将该姿态事件B上报，电子设备可以基于该姿态事件B确定电子设备的设备形态为折叠态，触发内屏熄灭，外屏点亮。关于该方式2的详细描述可以参考前述对方式2的描述，此处不再赘述。
后续，姿态传感器可以继续获取姿态事件(例如第二帧姿态事件等)，并将后续获取的姿态事件进行上报。且，霍尔传感器也可以上报霍尔事件。电子设备基于上报的事件(姿态事件或者霍尔事件)控制亮屏。
关于情况21中电子设备控制屏幕亮屏涉及的流程可以参考下述对图10的描述，此处不再赘述。
情况22：初始状态为展开(非灭屏)，在展开(非灭屏)时闭合电子设备。其中，电子设备初始状态为展开包括：电子设备在闭合之前，电子设备的设备形态为展开态，通常来说大于“展开切折叠角度+补充角度2”，例如内屏夹角为180°或者接近180°是电子设备的设备形态可以为展开态。非灭屏是指电子设备的内屏以及外屏中至少一个点亮。
如图9B所示，情况22中，电子设备的初始状态为非灭屏，则姿态传感器开启。在闭合电子设备的过程中，在内屏夹角从接近大于“全展开切半展开”角度，例如180°闭合到小于或者等于“全展开切半展开”角度(例如145°)的情况下，姿态传感器上报姿态事件。此时，该姿态事件为半展开态。其中，姿态传感器上报半展开态的位置可以如姿态工作轴中白色三角形处。
后续，在内屏夹角从“全展开切半展开”角度(例如145°)闭合到小于或者等于“展开切折叠角度+补充角度2”(例如60°)的情况下，姿态传感器上报姿态事件。此时，该姿态事件为折叠态，电子设备基于该折叠态使得内屏熄灭，外屏点亮。其中，姿态传感器上报折叠态的位置可以如姿态工作轴中黑三角形处。
应该理解的是，初始状态为展开(非灭屏)，闭合电子设备到内屏夹角至“小于或者等于“展开切折叠角度+补充角度2”(例如60°)时使得内屏熄灭、外屏点亮。涉及的内容包括但不限于以下内容中的部分或者全部：
内容21：初始状态为展开，且内屏熄灭、外屏点亮的情况下，闭合至“小于或者等于“展开切折叠角度+补充角度2”(例如60°)时，保持内屏熄灭、外屏点亮。
内容22：初始状态为展开，且内屏点亮、外屏熄灭的情况下，闭合至“小于或者等于“展开切折叠角度+补充角度2”(例如60°)时，触发内屏熄灭、外屏点亮。
内容23：初始状态为展开，且内屏点亮、外屏点亮的情况下，闭合至“小于或者等于“展开切折叠角度+补充角度2”(例如60°)时，触发内屏熄灭，保持外屏点亮。
后续，在内屏夹角从“展开切折叠角度+补充角度2”(例如60°)闭合到小于或者等于“远离切接近”角度(例如5°)的情况下，霍尔传感器上报霍尔事件。此时，该霍尔事件为接近态，电子设备将该接近态映射成为折叠态，与姿态传感器上报的折叠态相同，则电子设备不对该霍尔事件进行处理，继续保持内屏熄灭，外屏点亮。其中，霍尔传感器上报折叠态的位置可以如霍尔工作轴中白色三角形处。
该情况22中，在展开(非灭屏)时闭合电子设备的情况下，相比于前述实施1，该情况下，电子设备可以更早触发内屏熄灭，外屏点亮。
关于情况22中电子设备控制屏幕亮屏涉及的流程可以参考下述对图11的描述，此处不再赘述。
情况23：初始状态为展开(灭屏)，在展开(灭屏)时闭合电子设备。此时，由于灭屏的情况下姿态传感器不工作。因此，闭合电子设备的过程中，涉及的首个设备形态是基于霍尔传感器确定的。在内屏夹角闭合到小于或者等于“远离切接近”角度(例如5°)的情况下，霍尔传感器上报霍尔事件。此时，该霍尔事件为接近态，电子设备将该接近态映射成为折叠态，保持内屏和外屏熄灭。该情况23中霍尔传感器以及姿态传感器工作的示意图，与前述图6D相似，可以参考前述对图6D的描述，将其中的“展开切折叠”角度替换成为“展开切折叠角度+补充角度2”即可，此处不再赘述。
在另一些可能的情况下，情况23中，在内屏夹角闭合到小于或者等于“远离切接近”角度(例如5°)的情况下，霍尔传感器上报霍尔事件。此时，该霍尔事件为接近态，电子设备将该接近态映射成为折叠态后，还可以触发外屏点亮，保持内屏熄灭。
图10示出了情况21中电子设备控制屏幕亮屏时，各个模块间的交互流程。
下面结合图9A以及图10详细描述初始状态为闭合(灭屏或非灭屏)，展开电子设备时控制屏幕亮屏的过程。该过程涉及的主要模块包括霍尔传感器、姿态传感器、传感器服务、设备状态管理服务器、屏幕管理模块。该过程可以参考下述对步骤S101-步骤S113的描述。

参考前述图9A中的霍尔工作轴，闭合(灭屏或非灭屏)时展开电子设备的情况下，内屏夹角在0°至“接近切远离”角度(例如10°)之间时，霍尔传感器获取的霍尔事件为接近态。该接近态可以被映射成为折叠态。内屏夹角在大于或者等于“接近切远离”角度时，霍尔传感器获取的霍尔事件为远离态。该远离态可以被映射成为展开态。其中，展开态可以为半展开态也可以为全展开态，本申请实施例对此不作限定。
S102.内屏夹角从角度A0(接近0°)展开至“接近切远离”角度(例如10°)时，霍尔传感器确定设备形态为远离态，并将该远离态作为霍尔事件上报至传感器服务。
步骤S102中，霍尔传感器上报霍尔事件(远离态)的一个示例性位置可以为图9A示出的霍尔工作轴中黑色三角形处。

设备状态管理服务器可以将该霍尔事件(远离态)映射成为展开态。
S104.外屏是否熄灭。
在外屏点亮(未熄灭)的情况下，设备状态管理服务器可以执行下述步骤S105a使得外屏熄灭，以及内屏点亮。
在外屏熄灭的情况下，设备状态管理服务器可以执行下述步骤S105b使得内屏点亮，外屏继续保持熄灭。
S105a.通知屏幕管理模块进行切屏，使得内屏点亮，外屏熄灭。
在一些可能的实现方式中，屏幕管理模块可以利用电源管理服务器对内屏进行上电，以及对外屏进行下电使得外屏熄灭。
窗口管理服务器可以绘制显示内容，在内屏上电之后，将显示内容显示在内屏中，以使得内屏被点亮。
S105b.通知屏幕管理模块控制内屏点亮。
在一些可能的实现方式中，屏幕管理模块可以利用电源管理服务器对内屏进行上电。
窗口管理服务器可以绘制显示内容，在内屏上电之后，将显示内容显示在内屏中，以使得内屏被点亮。
这里应该理解的是，在灭屏的情况下，姿态传感器未开启，在设备状态管理服务器确定设备形态为展开态后，可以触发开启姿态传感器。
S105c.设备状态管理服务器向传感器服务发起注册姿态传感器的请求。设备状态管理服务器在注册姿态传感器之后。在姿态传感器开启的情况下，即可以获取到姿态传感器上报的姿态事件。其中，步骤S105c的执行时机与步骤S105a、步骤S105b的执行时机没有先后之分。
S106.传感器服务器通知启动姿态传感器。
S107.姿态传感器基于内屏夹角α确定姿态事件，该姿态事件包括折叠态、半展开态、全展开态等设备形态中的一个。
参考前述图9A中的姿态工作轴。闭合(灭屏或非灭屏)时展开电子设备的情况下，内屏夹角在0°至“折叠切展开角度+补充角度1”之间时，姿态传感器获取的姿态事件为折叠态。内屏夹角在“折叠切展开角度+补充角度1”至“半展开切全展开”角度之间时，姿态传感器获取的姿态事件为半展开态。内屏夹角在“半展开切全展开”角度至180°之间时，姿态传感器获取的姿态事件为全展开态。
S108.姿态传感器确定该姿态事件是否为姿态传感器上传的首帧姿态事件。
在确定该姿态事件为首帧姿态事件的情况下，为了处理该首帧姿态事件为折叠态，与霍尔传感器上报的远离态所映射的展开态冲突的情况，可以执行下述步骤S109b、或者执 行步骤S109b以及步骤S110以确定是否将该折叠态进行上报。
在确定该姿态事件不为首帧姿态事件的情况下，可以执行下述步骤S109a。
S109a.姿态事件相比于前一帧发生变化时，姿态传感器将姿态事件上报至传感器服务。
这里应该理解的是，姿态传感器上报姿态事件的时机包括：姿态事件为首帧时，在满足条件1之后可以上报，即首帧姿态事件默认相比与前一帧发生了变化。或者，非首帧姿态事件相比于前一帧发生变化时可以上报，没有发生变化则不上报。其中，条件1包括：首帧姿态事件不为折叠态，或者，姿态传感器确定内屏夹角小于阈值角度。对于该阈值角度的描述可以参考下述步骤S110中对阈值角度的描述，此处暂不赘述。
S109b.姿态传感器确定该首帧姿态事件是否为折叠态。
在确定该首帧姿态事件不为折叠态的情况下，姿态传感器可以执行下述步骤S109a，将该首帧姿态事件进行上报。
在确定该首帧姿态事件为折叠态时，在一些可能的情况下，姿态传感器可以执行下述步骤S110，进一步确定内屏夹角是否小于阈值角度，该阈值角度即为前述涉及的预设角度7，例如可以取值为4°。在内屏夹角大于阈值角度的情况下，执行步骤S109a将该首帧姿态事件进行上报。在内屏夹角大于阈值角度的情况下，执行步骤S111，不将该首帧姿态事件进行上报。在另一些可能的情况下，姿态传感器可以不执行下述步骤S110，直接执行下述步骤S111。不将该首帧姿态事件进行上报。
S110.姿态传感器确定内屏夹角α是否小于阈值角度。
该阈值角度即为前述涉及的预设角度7，例如可以取值为4°。关于预设角度7的相关描述可以参考前述内容，此处不再赘述。

在姿态传感器确定内屏夹角α大于阈值角度的情况下，执行下述步骤S111，可以不将该首帧姿态事件上报至传感器服务，使得内屏保持亮屏，外屏保持灭屏。
S111.姿态传感器不将该首帧姿态事件上报至传感器服务，使得内屏保持亮屏，外屏保持灭屏。
S112.姿态传感器将姿态事件上报至设备状态管理服务器。
S113.在姿态事件为折叠态的情况下，设备状态管理服务器通过屏幕管理模块控制切屏，使得内屏熄灭，外屏点亮。
该步骤S113中的姿态事件可以分为以下几种结果进行描述。
结果21：在该姿态事件为折叠态，且为首帧姿态事件的情况下，表示此时霍尔传感器失效时，误报现在是远离态(其实是接近态，用户也许并不期望展开电子设备)，执行步骤S113可以基于姿态传感器纠正霍尔传感器的误报，使得电子设备触发内屏熄灭，外屏点亮。
结果22：在该姿态事件为折叠态，且不为首帧姿态事件的情况下，表示此时用户在展开电子设备到内屏夹角大于或者等于“展开切折叠角度+补充角度2”之后，又重新闭合电子设备。使得电子设备从展开态又转换到折叠态了。这时电子设备可以触发内屏熄灭，外屏点亮。
这里应该理解的时，在姿态事件不为折叠态的情况下，可以为半展开态或者全展开态，与霍尔传感器上报的远离态所映射的展开态一致，设备状态管理服务器可以不对该展开态进行处理，保持内屏点亮，外屏熄灭。
图11示出了情况22中电子设备控制屏幕亮屏时，各个模块间的交互流程。
下面结合图9B以及图11详细描述初始状态为展开(非灭屏)，闭合电子设备时控制屏幕亮屏的过程。该过程涉及的主要模块包括霍尔传感器、姿态传感器、传感器服务、设备状态管理服务器、屏幕管理模块。该过程可以参考下述对步骤S201-步骤S205的描述。
S201.霍尔传感器获取霍尔事件，该霍尔事件包括接近态、远离态等设备形态中的一个，在检测到设备形态发生变化的情况下，向传感器服务上报霍尔事件，其中，接近态可以被映射为折叠态，远离态可以被映射为展开态。
参考图9B中的霍尔工作轴，展开(非灭屏)时闭合电子设备的情况下，内屏夹角在180°至“远离切接近”角度(例如5°)之间时，霍尔传感器获取的霍尔事件为远离态。该远离态可以被映射成为展开态。内屏夹角在小于或者等于“远离切接近”角度时，霍尔传感器获取的霍尔事件为接近态。该接近态可以被映射成为折叠态。其中，展开态可以为半展开态也可以为全展开态，本申请实施例对此不作限定。
应该理解的时，虽然霍尔传感器可以工作，但是在展开(非灭屏)时闭合电子设备的情况下，设备状态管理服务器接收到的是姿态传感器在内屏夹角闭合到“展开切折叠角度+补充角度2”(例如60°)时的折叠态。即，内屏夹角闭合到“展开切折叠角度+补充角度2”(例如60°)时，设备状态管理服务器即可触发内屏熄灭，外屏点亮。在姿态传感器损坏或者因姿态传感器依赖的器件损坏而失效的情况下，设备状态管理服务器可以基于霍尔传感器在内屏夹角闭合到“远离切接近”角度(例如5°)时触发内屏熄灭，外屏点亮。其中，关于设备状态管理服务器基于姿态传感器触发内屏熄灭，外屏点亮的过程可以参考下述对步骤S202-步骤S205的描述。
S202.姿态传感器获取姿态事件，该姿态事件包括折叠态、半展开态、全展开态等设备形态中的一个，在检测到设备形态发生变化的情况下，向传感器服务上报姿态事件。
参考前述图9B中的姿态工作轴。展开(非灭屏)时闭合电子设备的情况下，内屏夹角在180°至“全展开切半展开”(例如145°)角度之间时，姿态传感器获取的姿态事件为全展开态。内屏夹角在“全展开切半展开”角度至“展开切折叠角度+补充角度2”(例如60°)之间时，姿态传感器获取的姿态事件为半展开态。内屏夹角在“展开切折叠角度+补充角度2”至0°之间时，姿态传感器获取的姿态事件为折叠态。
应该理解的是，姿态传感器上报姿态事件的时机包括：姿态事件为首帧时可以上报。或者，非首帧姿态事件相比于前一帧发生变化时可以上报，没有发生变化则不上报。
S203.内屏夹角从角度A3(小于180°大于60°)折叠到“展开切折叠角度+补充角度2”(例如60°)时，姿态传感器确定设备形态为折叠态，并将该折叠态作为姿态事件上报至传感器服务。
步骤S203中，姿态传感器上报姿态事件(折叠态)的一个示例性位置可以为图9B示出的姿态工作轴中黑色三角形处。
S204.将姿态事件上报至设备状态管理服务器，以使得设备状态管理服务器确定设备形态为折叠态。
S205.通知屏幕管理模块控制切屏，使得内屏熄灭，外屏点亮。
在一些可能的实现方式中，屏幕管理模块可以利用电源管理服务器对外屏进行上电，以及对内屏进行下电使得内屏熄灭。
窗口管理服务器可以绘制显示内容，在外屏上电之后，将显示内容显示在外屏中，以使得外屏被点亮。
应该理解的是，情况23中电子设备控制屏幕亮屏时，各个模块间的交互流程前述与情况22中电子设备控制屏幕亮屏时，各个模块间的交互流程相似，不同之处在于姿态传感器未开启，以霍尔传感器上报的霍尔事件确定设备形态。可以参考前述对图11中相关内容的描述，此处不再赘述。
应该理解的是，本申请涉及的在电子设备在展开或者闭合时合理亮屏的场景可以包括前述涉及的场景1以及场景2。其中，场景1与实施例1中的情况11以及实施例2中的情况21中描述的内容对应。场景2与实施例1中的情况13以及实施例2中的情况22中描述的内容对应。
除了场景1以及场景2，电子设备在展开或者闭合时合理亮屏的场景还可以包括其他场景，例如下述涉及的场景3-场景6。该场景3-场景6可以在实施例2中实现。
场景3：电子设备的初始状态为闭合，且，内屏以及外屏均熄灭时，展开电子设备的情况下。在电子设备展开内屏夹角至大于或者等于“接近切远离”角度(例如10°)时，霍尔传感器上报设备形态为远离态，电子设备将该远离态映射成为展开态，触发内屏点亮，外屏熄灭，且开启姿态传感器。后续，继续展开电子设备到“接近切远离”角度至“折叠切展开角度+补充角度1”(例如65°)之间后，停止展开，且不闭合电子设备，电子设备可以始终保持点亮内屏，熄灭外屏。不会在预设时间T(例如1s)后，触发内屏熄灭，外屏点亮。因为在实施例2中，在姿态传感器上传的首帧姿态事件为折叠态且内屏夹角大于预设角度7(例如4°)的情况下，电子设备不会获取到姿态传感器上报的首帧姿态事件，因此，电子设备可以基于霍尔传感器上报的远离态继续使得内屏点亮，外屏熄灭。
场景4：电子设备的初始状态为闭合，且，内屏以及外屏均熄灭时，展开电子设备的情况下。在电子设备展开内屏夹角至大于或者等于“接近切远离”角度时，霍尔传感器上报设备形态为远离态，电子设备将该远离态映射成为展开态，触发内屏点亮，保持外屏熄灭，且开启姿态传感器。后续，继续展开电子设备，时刻A，内屏夹角大于或者等于“折 叠切展开角度+补充角度1”时，姿态传感器上报设备形态为展开态，电子设备保持点亮内屏，熄灭外屏。时刻B，停止展开电子设备，闭合电子设备到内屏夹角小于或者等于“展开切折叠角度+补充角度2”(例如60°)时，电子设备基于姿态传感器确定设备形态为折叠态，触发内屏熄灭，外屏点亮。其中，时刻A与时刻B的时间差可以小于预设时间T。因为在实施例2中，在姿态传感器获取的非首帧姿态事件在于前一帧姿态事件不同时可以上报，不受预设时间T(实施例1中涉及的)之后才上报的约束。
场景5：电子设备的初始状态为闭合(例如内屏夹角等于0°或者接近0°)，且无论是非灭屏还是灭屏，展开电子设备的情况下。在电子设备展开内屏夹角至大于或者等于“接近切远离”角度时，霍尔传感器上报设备形态为远离态，电子设备将该远离态映射成为展开态，触发内屏点亮，保持外屏熄灭，且开启姿态传感器。后续，继续展开电子设备，内屏夹角处于大于或者等于“接近切远离”角度(例如10°)且小于“折叠切展开角度+补充角度1”(例如65°)时，电子设备保持内屏点亮，外屏熄灭。后续，停止展开电子设备且开始闭合电子设备，时刻C，闭合电子设备到内屏夹角小于或者等于“远离切接近”角度(例如5°)时，电子设备基于霍尔传感器确定设备形态为接近态，电子设备将该接近态映射成为折叠态，触发内屏熄灭，外屏点亮。该场景5实施例2可以实现，实施1无法实现，其原因在于：实施例1中，在非灭屏状态下，姿态传感器开启，电子设备不基于霍尔传感器上报的霍尔事件进行处理。因此时刻C，闭合电子设备到内屏夹角小于或者等于“远离切接近”角度(例如5°)时，霍尔传感器检测到接近态之后，上报该接近态，但是电子设备不基于该接近态进行处理，因此无法触发内屏熄灭，外屏点亮。其中，在电子设备的初始状态为闭合且灭屏的情况下，实施1无法实现该场景5的原因还包括：姿态传感器上报的姿态事件会在T时刻之后才会被电子设备进行处理。
场景6：电子设备的初始状态为展开(例如内屏夹角等于180°或者接近180°)，且，非灭屏的情况下，闭合电子设备到内屏夹角小于“展开切折叠角度+补充角度2”(例如60°)且大于“展开切折叠角度”(例如40°)的情况下，姿态传感器确定此时设备形态为折叠态，电子设备保持内屏熄灭，外屏点亮。此时，在时刻D停止闭合电子设备，然后开始展开电子设备，在内屏夹角展开到大于或者等于“折叠切展开角度+补充角度1”(例如65°)时，姿态传感器确定设备形态变更为半展开态，则电子设备基于该半展开态初触发内屏点亮，外屏熄灭。该场景6实施例2可以实现，实施1无法实现，其原因在于：实施例1中，在时刻D停止闭合电子设备时，由于内屏夹角大于“展开切折叠角度”(例如40°)且小于“展开切折叠角度+补充角度2”(例如60°)时，实施例1中，确定此时电子设备的设备形态为半展开态不是折叠态，这时刻D之后，展开电子设备到大于或者等于“折叠切展开角度+补充角度1”(例如65°)时，仍然处于半展开态。由于设备形态没有发生改变，则姿态传感器不会将该半展开态上报，因此电子设备无法基于姿态传感器确定此时为折叠态，则继续保持内屏点亮，外屏熄灭，无法切换到外屏点亮，内屏熄灭。
在一些可能的实施例中，可以不使用霍尔传感器，基于姿态传感器控制亮屏即可。在电子设备的初始状态为闭合(灭屏或者非灭屏)，展开电子设备的过程中，在展开到内屏夹角大于或者等于预设角度3(例如前述涉及的“折叠切展开角度”或者“折叠切展开角 度+补充角度1”)时，姿态传感器即可确定电子设备的设备形态从折叠态更新为了展开态(半展开态或者全展开态)，电子设备即可处于内屏点亮，外屏熄灭的状态。在电子设备的初始状态为展开(灭屏或者非灭屏)，闭合电子设备的过程中，在闭合到内屏夹角大于或者等于预设角度2(例如前述涉及的“展开切折叠角度”或者“展开切折叠角度+补充角度2”)时，姿态传感器即可确定电子设备的设备形态从展开态更新为了折叠态，电子设备即可处于内屏熄灭，外屏点亮的状态。
