Description

隐藏信息显示方法、设备、芯片系统、介质及程序产品
本申请要求于2022年8月1日提交中国专利局、申请号为202210918323.3，发明名称为“隐藏信息显示方法、设备、芯片系统、介质及程序产品”的中国专利的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及电子技术领域，尤其涉及一种隐藏信息显示方法、设备、芯片系统、介质及程序产品。
背景技术
随着终端设备的迅速发展与普及，终端设备的功能也越来越强大，人们使用终端设备的频率越来越高，因此，终端设备中保存着大量的信息，比如私人照片、临时感想等隐私信息。
现有技术中，终端设备(如折叠屏手机)通常是通过建立隐藏文件夹/隐私空间等方式实现信息的隐藏。在实现本发明的过程中，发明人发现现有技术至少存在如下技术问题：用户使用终端设备进入了界面a，用户想要查看隐私空间的信息，需要退出界面a，再进入隐私空间。终端设备进入隐私空间后显示隐私空间的界面，而不显示界面a。随着科学技术的发展，终端设备的显示屏从全面屏发展到折叠屏。如何利用折叠屏相对于全面屏所特有的可折叠特征来显示所隐藏的信息，提高用户使用体验，成为待解决的问题。
发明内容
本申请实施例提供一种隐藏信息显示方法、设备、芯片系统、介质及程序产品，在终端设备处于半展开状态时，根据终端设备的第一姿态调整显示屏上原有的显示内容的显示区域，以可以同时显示显性内容(第一界面)和隐藏信息。
第一方面，本申请实施例提供了一种隐藏信息显示方法，应用于显示屏可折叠的终端设备，该方法包括：在显示屏的第一显示区域上显示第一界面；接收第一操作，其中第一操作用于指示显示隐藏信息；响应于第一操作，根据终端设备的第一姿态确定第一界面的第二显示区域，其中第二显示区域是第一显示区域的部分区域，第一姿态指示终端设备处于半展开状态；根据第二显示区域和隐藏信息在第一显示区域上确定隐藏显示区域；其中，隐藏显示区域与第二显示区域不重叠；在第二显示区域上显示第一界面，在隐藏显示区域上显示隐藏信息。
在本申请实施例中，通过终端设备响应第一操作，获取终端设备的第一姿态。当第一姿态指示终端设备处于半展开状态，根据第一姿态确定第一界面的第二显示区域，第二显示区域小于第一显示区域。也即在确定第一界面的第二显示区域后，显示屏上有空闲显示区域可以用于显示隐藏信息。若根据终端设备的第一姿态确定终端设备未处于半展开状态，则无法根据第一姿态确定出第一界面的第二显示区域，进而显示屏上无空闲区域显示隐藏信息。由此，通过利用显示屏可折叠特征，在显示屏折叠后使得终端设备处于半展开状态后，根据终端设备的第一姿态调整第一界面的第二 显示区域，以确定出用于显示隐藏信息的隐藏显示区域，进而可以同时显示第一界面和隐藏信息。
在一种可能的设计方式中，隐藏显示区域包括相交的第一边与第二边，第二显示区域包括相交的第三边与第四边，第一边与第三边重合，第二边与第三边垂直，第二边与第四边垂直。
在本申请实施例中，隐藏显示区域的第一边与第二显示区域的第三边重合，隐藏显示区域的第二边与第二显示区域的第三边垂直，隐藏显示区域的第二边与第二显示区域的第四边垂直，也即在显示屏上隐藏显示区域与第二显示区域垂直。在包括多个隐藏显示区域时，该多个隐藏显示区域与第二显示区域垂直，则隐藏显示区域与第二显示区域之间的垂直关系构建出一个立体的视觉效果，使得用户看隐藏信息时的视觉效果：以显示屏作为透明窗口，用户透过窗口能够看到窗口背后的隐藏信息，该隐藏信息就像存在显示屏背后的立体空间(也即隐藏显示空间)中。
在一种可能的设计方式中，显示屏包括第一屏和第二屏，根据第二显示区域和隐藏信息在第一显示区域上确定隐藏显示区域包括：确定隐藏信息在隐藏显示空间的第一位置，其中隐藏显示空间由第一屏与第二屏确定；根据第二显示区域与第一位置在第一显示区域上确定隐藏显示区域。
其中，其中隐藏显示空间由处于半展开状态的终端设备的第一屏和第二屏确定。该隐藏显示空间类似于上述隐私空间，存着用户所隐藏起来的隐藏信息，但不同在于隐私空间是二维的空间，而本申请隐藏显示空间是三维的空间，进而使得本申请实施例中显示屏300所显示的隐藏信息与第一界面呈现一种立体效果。
在本申请实施例中，基于要实现显示隐藏信息的视觉效果为：以显示屏作为透明窗口，用户透过窗口能够看到窗口背后的隐藏信息，该隐藏信息就像存在显示屏背后的立体空间(也即隐藏显示空间)中。为此，需要依据隐藏信息在隐藏显示空间的第一位置，将隐藏信息投影至显示屏，并依据第二显示区域在第一显示区域上确定隐藏显示区域。
在一种可能的设计方式中，确定隐藏信息在隐藏显示空间的第一位置包括：确定隐藏信息所处的虚拟显示屏，其中虚拟显示屏垂直于第一屏所在的平面；根据虚拟显示屏与第二屏的关系确定第一位置，其中第一位置包括虚拟显示屏位于第二显示区域的上方、侧方或下方。
其中，虚拟显示屏也可以垂直于第二屏所在的平面；然后根据虚拟显示屏与第一屏的关系确定第一位置，其中第一位置包括虚拟显示屏位于第二显示区域的上方、侧方或下方。
在本申请实施例中，终端设备可以包括多个虚拟显示屏，确定隐藏信息显示在哪个虚拟显示屏，确定显示有隐藏信息的虚拟显示屏。则确定隐藏信息在隐藏显示空间的第一位置，即确定显示有隐藏信息的虚拟显示屏在隐藏显示空间的第一位置。基于要实现上述隐藏信息的视觉效果，为此需要确定虚拟显示屏与显示屏的位置关系，由此确定显示有隐藏信息的虚拟显示屏在隐藏显示空间的第一位置，也即确定该虚拟显示屏与显示屏的位置关系，具体为，确定该虚拟显示屏与第一屏或第二屏的位置关系。若是以第一屏所在平面为基准面，则确定该虚拟显示屏与第二屏的位置关系。若是以第二屏所在平面为基准面，则确定该虚拟显示屏与第一屏的位置关系。
在本申请实施例中，虚拟显示屏与第一屏或第二屏的位置关系也即在创建虚拟显示屏时，该虚拟显示屏所设置的位置，如可以包括该虚拟显示屏与第一屏或第二屏的哪个边重合。
在一种可能的设计方式中，根据第二显示区域与第一位置在第一显示区域上确定隐藏显示区域包括：根据第二显示区域在第一显示区域上确定第三显示区域，其中第三显示区域与第二显示区域构成第一显示区域；将隐藏信息所处的虚拟显示屏沿着预设的第一视线反向投影至第三显示区域，得到隐藏显示区域。
如上述，在确定第二显示区域后，显示屏上有空闲显示区域，该空闲显示区域即第三显示区域，进而可以在该第三显示区域上确定隐藏显示区域。
在本申请实施例中，第一位置也即隐藏信息所处的虚拟显示屏，将该虚拟显示屏沿着预设的第一视线反向投影至第三显示区域，得到隐藏显示区域。
在一种可能的设计方式中，根据第二显示区域与第一位置在第一显示区域上确定隐藏显示区域包括：根据第二显示区域在第一显示区域上确定第三显示区域，其中第三显示区域与第二显示区域构成第一显示区域；根据预设比例缩放隐藏信息所处的虚拟显示屏，得到缩放后的虚拟显示屏；根据缩放后的虚拟显示屏确定第三显示区域上的隐藏显示区域。
在一种可能的设计方式中，隐藏显示区域的大小与显示屏的折叠角度相关。
在本申请实施例中，显示屏的折叠角度变化，则隐藏显示空间大小变化，进而隐藏显示区域的大小也发生变化。隐藏显示区域的大小随着显示屏的折叠角度变化而变化，以体现出隐藏显示区域是透射隐藏显示空间的内容。
在一种可能的设计方式中，当显示屏为向内翻折时，随着第一屏与第二屏之间的夹角在第一范围区间内逐渐变小，隐藏显示区域逐渐变大。随着第一屏与第二屏之间的夹角在第二范围区间内逐渐变小，隐藏显示区域逐渐变小，其中第一范围区间为[90°，180°)；第二范围区间为(0°，90°]。
当显示屏为内折屏时，第一屏与第二屏之间的夹角从180°变化到90°，隐藏显示区域逐渐变大，第一屏与第二屏之间的夹角从90°变化到0°，隐藏显示区域逐渐变小，也即第一屏与第二屏之间的夹角为90°时，隐藏显示区域最大，也即隐藏显示区域在显示屏上的面积最大。
在一种可能的设计方式中，当显示屏为向外翻折时，随着第一屏与第二屏之间的夹角在第三范围区间内逐渐变小，隐藏显示区域逐渐变大，其中第三范围区间为(0°，180°)。
当显示屏为外折屏时，第一屏与第二屏之间的夹角从0°变化到180°，隐藏显示区域逐渐变大，也即隐藏显示区域在显示屏上的面积逐渐变大。
第二方面，本申请实施例提供了一种终端设备，一个或多个存储器、可折叠的显示屏和一个或多个处理器，一个或多个存储器与一个或多个处理器耦合，可折叠的显示屏与一个或多个处理器通信，一个或多个存储器用于存储计算机程序代码，程序代码包括计算机指令，当一个或多个处理器执行计算机指令时，使得终端设备执行如上述的隐藏信息显示方法。
第三方面，本申请实施例提供了一种芯片系统，芯片系统应用于包括显示屏的终端设备；芯片系统包括一个或多个接口电路和一个或多个处理器；接口电路和处理器通过线路互联；接口电路用于从终端设备的存储器接收信号，并向处理器发送信号，信号包括存储器中存储的计算机指令；当处理器执行计算机指令时，终端设备执行如上述的隐藏信息显示方法。
第四方面，本申请实施例提供了一种计算机存储介质，包括计算机指令，当计算机指令在终端设备上运行时，使得终端设备执行如上述的隐藏信息显示方法。
第五方面，本申请实施例提供了一种计算机程序产品，当计算机程序产品在计算机上运行时，使得计算机执行如上述的隐藏信息显示方法。

上述隐私空间40的访问入口的位置固定在系统界面20，当用户100打开其他应用程序，进入了应用界面。用户想再打开隐私空间40，需要退出应用界面，切换到入口所在的系统界面20，操作不便，且无法同时显示隐私空间与应用界面。
鉴于此，本申请实施例提供一种隐私信息显示方法，应用于显示屏可折叠的终端设备，该隐私 信息显示方法包括：终端设备在显示屏的第一显示区域上显示第一界面。终端设备接收第一操作，其中第一操作用于指示显示隐藏信息。终端设备响应于第一操作，根据终端设备的第一姿态确定第一界面的第二显示区域，其中第二显示区域是第一显示区域的部分区域，第一姿态指示显示屏处于半展开状态。终端设备根据第二显示区域和隐藏信息在第一显示区域上确定隐藏显示区域；其中，隐藏显示区域与第二显示区域不重叠。终端设备在第二显示区域上显示第一界面，在隐藏显示区域上显示隐藏信息。用户可以在任意界面执行第一操作，终端设备响应该第一操作，若终端设备处于半展开状态且存有隐藏信息，可以同时显示第一界面与隐藏信息。
在对本申请实施例进行详细的解释说明之前，先对本申请实施例涉及的应用场景予以介绍。
请参阅图2，用户100可以通过手势、折叠、触控等方式操作终端设备200。终端设备200上可以搭载有操作系统，操作系统内置有系统级应用程序。用户100也可以根据自己的需要来安装/卸载应用程序。终端设备200包括显示屏300，该显示屏300可折叠，该显示屏300也可称为折叠屏。显示屏300包括两个分屏(第一屏301和第二屏302)。第一屏301和第二屏302可以通过铰链连接。第一屏301和第二屏302之间能够相对转动，可以通过转动第一屏301和第二屏302来改变终端设备200的状态。当终端设备200处于半展开状态时，用户100可以通过第一操作触发终端设备200显示隐藏信息。该隐藏信息的显示可以给用户100一种新的视觉体验为：用户100在显示屏300上看隐藏信息就像用户100透过显示屏300看到存(或显示)在隐藏显示空间中的隐藏信息，其中隐藏显示空间由处于半展开状态的终端设备200的第一屏301和第二屏302确定。该隐藏显示空间类似于上述隐私空间，存着用户100所隐藏起来的隐藏信息，但不同在于隐私空间是二维的空间，而本申请隐藏显示空间是三维的空间，进而使得本申请实施例中显示屏300所显示的隐藏信息与第一界面呈现一种立体效果。
在本申请实施例中，终端设备具有隐藏信息显示功能。在终端设备200启用隐藏信息显示功能时，终端设备200执行本申请实施例提供的隐藏信息显示方法，如图6、图10所示的方法实施例中记载的全部步骤，以实现对隐藏信息的显示。
其中，隐藏信息显示功能可以作为终端设备200的一个功能实现，也可以作为终端设备200中原有应用程序的一个子功能实现，如隐藏信息显示功能作为华为手机的设置应用程序的一个子功能实现。终端设备200在运行设置应用程序的隐藏信息显示功能或运行隐藏信息显示应用程序时，终端设备200执行本申请实施例提供的隐藏信息显示方法。
示例性的，本申请实施例中的终端设备200又称为终端、用户设备，可以是手机、平板电脑、桌面型、膝上型、手持计算机、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本，以及蜂窝电话、个人数字助理(personal digital assistant，PDA)、增强现实(augmente dreality，AR)\虚拟现实(virtual reality，VR)设备等包括可折叠显示屏的终端设备，本申请实施例对该终端设备200的具体形态不作特殊限制。
下述附图实施例均以终端设备200为手机进行举例说明，手机仅为示意性举例，并不构成对本申请实施例的限定。
第一屏301和第二屏302之间的夹角不同时，终端设备200可以形成不同的物理状态，例如折叠状态、半展开状态、展开状态等。应理解，本申请中对于终端设备200的显示屏300的物理状态的划分以及对各个物理状态的定义不作限定。
请参阅图3A至图3C，示例性地给出本申请一实施例提供的一种朝外翻折显示屏300时终端 设备200的状态。其中，显示屏300朝外翻折，可以称该显示屏300为外折屏。图3A示意朝外翻折的终端设备200处于展开状态，第一屏301和第二屏302之间的夹角为第一角度α。处于展开状态的终端设备200可沿折叠边303按照图3A所示的折叠方向翻折，如图3B所示终端设备200处于半展开状态。当终端设备200处于半展开状态时，第一屏301和第二屏302之间的夹角为第二角度β。终端设备200继续沿折叠方向折叠，如图3C所示终端设备200处于折叠状态。当终端设备200处于折叠状态时，第一屏301和第二屏302相背对，第一屏301和第二屏302之间的夹角为第三角度ε(如图5所示)。
请参考图4A至图4B，示例性地给出本申请另一实施例提供的一种朝内翻折显示屏300的终端设备200的状态。其中，显示屏300朝内翻折，可以称该显示屏300为内折屏。图4A示意朝内翻折的终端设备200处于展开状态，第一屏301和第二屏302之间的夹角为第一角度α。处于展开状态的终端设备200可沿折叠边303按照图4A所示的折叠方向翻折，如图4B所示终端设备200处于半展开状态。当终端设备200处于半展开状态时，第一屏301和第二屏302之间的夹角为第二角度β。终端设备200继续沿折叠方向折叠，如图4C所示终端设备200处于折叠状态。当终端设备200处于折叠状态时，第一屏301和第二屏302相对，第一屏301和第二屏302之间的夹角为第三角度ε(如图5所示)。第一屏301和第二屏302对用户不可见，图4C所示的304是第一屏301和第二屏302相接触的平面上的一条线。
可以理解的是，当终端设备200处于折叠状态时，可以在第一屏301或第二屏302显示界面；当终端设备200处于展开状态或半展开状态时，可以在第一屏301和第二屏302显示界面。
当终端设备200处于展开状态时，第一屏301和第二屏302之间的夹角为第一角度α。如图5所示，a2≤α≤180°，其中，a2大于90°且小于或等于180°，例如，a2可以是170°、180°等等。
当终端设备200处于半展开状态时，第一屏301和第二屏302之间的夹角为第二角度β。如图5所示，a1≤β≤a2。其中，a1大于0°且小于或等于90°，a2大于或等于90°且小于180°。例如，a1可以是90°，a2可以是150°。
当终端设备200处于折叠状态时，第一屏301和第二屏302之间的夹角为第三角度ε。如图5所示，0≤ε≤a1。其中，a1大于或等于0°且小于或等于90°。例如，a1可以是0°、5°等。需要说明的是，本申请中涉及的具体的取值范围仅是举例，而非限定。
在另一些实施例中，终端设备200可以左右折叠或者上下折叠；或者，终端设备200既可以上下折叠也可以左右折叠。本申请提供的隐藏信息显示方法可以适用于沿各种方向折叠的终端设备200。
其中，显示屏300可以是柔性显示屏。柔性显示屏包括采用柔性材质制作的折叠边303。该柔性显示屏的部分或全部采用柔性材质制作。柔性显示屏被折叠后形成的至少两个屏是一体结构的一个完整屏，只是被折叠形成了至少两部分。
又例如，该终端设备200的显示屏300可以为多屏显示屏。该多屏显示屏可包括多个(两个或两个以上)屏。这多个屏是多个单独的显示屏。这多个屏可依次通过折叠轴连接。每个屏可以绕与其连接的折叠轴转动，实现多屏显示屏的折叠。
下述实施例中以终端设备200处于展开状态时，第一屏301和第二屏302之间的夹角为180°，终端设备200处于折叠状态时，第一屏301和第二屏302之间的夹角为0°为例。
以下实施例中所涉及的技术方案均可以在上述终端设备200中实现。以下结合附图和应用场景对本实施例提供的隐藏信息显示方法进行详细介绍。应当理解的是，下面操作不一定按照顺序来精确地执行。相反，根据需要，可以按照倒序或同时处理各种步骤。同时，也可以将其他操作添加到这些过程中，或从这些过程移除某一步或数步操作。
请参阅图6，图6为本申请实施例提供的一种隐藏信息显示方法流程示意图。该隐藏信息显示方法可以由上述终端设备200执行。该方法包括如下步骤：
步骤S61：终端设备在显示屏的第一显示区域上显示第一界面。
示例性地，请参阅图7，终端设备200在显示屏300的第一显示区域400上显示第一界面500。图7中以第一显示区域400为显示屏300所能显示的全屏区域，第一界面500未占满第一显示区域400为例。可以理解，第一界面500也可以占满第一显示区域400，本申请对此不作具体限定。
在一些实施例中，第一界面500可以包括多个窗口。
在一些实施例中，第一显示区域400上还可以显示多个界面。
在一些实施例中，显示屏300可以分屏显示。例如第一屏301显示界面a，第二屏302上显示界面b，本申请对此不作具体限定。下述以第一屏301和第二屏302共同显示第一界面500为例。
其中，第一界面500可以为终端设备200上应用程序的应用界面也可以为终端设备200上操作系统的系统界面。
在一些实施例中，第一界面500可以是与隐藏信息相关的界面，如用户100在第一界面500上添加了隐藏信息。
在另一些实施例中，第一界面500为用户100使用终端设备200时，终端设备200上所显示的界面。该第一界面500可以不是与隐藏信息相关的界面，此时终端设备200上存有的隐藏信息可以关联也可以不关联终端设备200上的界面。
步骤S62：终端设备接收第一操作，其中第一操作用于指示显示隐藏信息。
在本申请实施例中，用户100想查看隐藏信息时，用户100可以启动终端设备200的隐藏信息显示功能。例如，用户100向终端设备200输入第一操作，以启动终端设备200的隐藏信息显示功能，指示终端设备200显示隐藏信息。
其中，隐藏信息与隐藏显示空间相关。在终端设备200处于半展开状态时，终端设备200响应用户100的第一操作，显示隐藏信息。用户100通过显示屏300看到隐藏信息时，用户100的视觉体验为：以显示屏300作为透明窗口，用户100透过窗口能够看到窗口背后的隐藏信息，该隐藏信息就像存在显示屏300背后的立体空间(也即隐藏显示空间)中。该视觉体验可以增强了可折叠的显示屏300的交互，突出了显示屏300可折叠的终端设备200的优势。该视觉体验带来了利用空间来隐藏信息的体验，让用户100有一种信息隐藏在显示屏300背后的立体空间中的真实感，实现一种空间层面的交互体验，提高用户100的使用体验。
下面介绍本申请实施例中的隐藏显示空间。
请一并参阅图8A至图8B，如上述终端设备200，下述假设将显示屏300当成透明窗口。以用户100朝向显示屏300上用于显示信息的一面为例。如图8A所示，处于展开状态的终端设备200，两个分屏(图未示第一屏301和第二屏302)处于同一平面。用户100透过窗口能看到显示屏300所在的二维平面801(终端设备200放置的二维平面801)。该二维平面801可以理解为图8A中显示屏300垂直投影至水平面800上的区域。如图8B所示，处于半展开状态的终端设备200，两个 分屏(第一屏301和第二屏302)具有一定的夹角。用户100透过窗口，除了能看到显示屏300所在的二维平面802外，还能观察到二维平面802和其中一个分屏(如图8B所示的第一屏301)之间的立体的隐藏显示空间803(如图8B中三角形区域)。该二维平面802可以理解为图8B中显示屏300垂直投影至水平面800上的区域，也即包括第一屏301和第二屏302投影至水平面800上的区域。
上述图8B以显示屏300朝内翻折为例介绍隐藏显示空间，显示屏300朝外翻折同理，在此不再赘述。
在终端设备200处于半展开状态时，用户100透过显示屏300能够额外观看到立体空间(隐藏显示空间803)，如图8B所示垂直于二维平面802(或水平面800)垂直方向上的空间。为了让用户100看到隐藏信息时，可以有上述的视觉体验，假设可以利用该立体空间象征性地存信息，在该立体空间所存的信息即为隐藏信息。该隐藏信息是借助垂直于二维平面(801、802)垂直方向上的空间来进行隐藏的，该隐藏信息可以称为空间隐藏信息。具体来说，可以视为在图8B所示的立体空间(隐藏显示空间803)内设置有虚拟显示屏(Virtual Display)，虚拟显示屏上可以显示用户100所隐藏的隐藏信息。在显示屏300显示隐藏信息时，将虚拟显示屏上所显示的隐藏信息显示至显示屏300上。
在本申请实施例中，对于终端设备200来说，其可以显示的内容包括显性内容和隐藏信息。显性内容即为第一界面500，隐藏信息即隐藏在隐藏显示空间803上虚拟显示屏的内容。在终端设备200处于半展开状态，用户100向终端设备200输入第一操作后，终端设备200可以在显示屏300上同时显示显性内容和隐藏信息。
下面介绍本申请实施例中的虚拟显示屏。
虚拟显示屏是相对于终端设备200的真实显示屏300(用户可见)而言的，虚拟显示屏用户100不可见。虚拟显示屏可以包括各种显示参数，比如，分辨率、显示屏尺寸等，虚拟显示屏的显示参数可以与真实显示屏300的显示参数一致。在一些实施例中，虚拟显示屏的显示参数还可以包括虚拟显示屏上的内容显示在显示屏300上的位置关系，也可以理解为隐藏信息在隐藏显示空间的第一位置。
在一些实施例中，终端设备200可使用显示管理器(Display Manager)创建虚拟显示屏。终端设备200还可以使用其他技术创建虚拟显示屏，创建虚拟显示屏为现有成熟技术，在此不再赘述。
在本申请实施例中，虚拟显示屏在空间直角坐标系中的位置可以由系统预置。
在一些实施例中，虚拟显示屏可以具有预设的大小(宽度/高度)。
在创建虚拟显示屏时，构建空间直角坐标系，可以基于显示屏300的其中一个分屏所在平面作为x、y轴所在平面，z轴垂直x、y轴所在平面。然后在垂直于x、y轴所在平面的平面上设置虚拟显示屏。如图8B所示，可以以放置在水平面800上的分屏(第二屏302)所在的平面作为x、y轴所在平面构建坐标系，x轴和y轴分别和第二屏302的两条相邻的边线平行，然后在y、z轴所在平面建立虚拟显示屏，这个角度的虚拟显示屏正对用户的视线。或者，在x、z轴所在平面创建虚拟显示屏。
具体地，请参阅图9，示例性提供本申请一实施例构建虚拟显示屏的示意，以终端设备200处于展开状态下、虚拟显示屏布局在第二屏302附近为例。
如图9所示，终端设备200处于展开状态。x轴平行显示屏300侧端所在直线，y轴平行于显 示屏300的顶端所在直线。z轴垂直于x轴和y轴所在的平面(也即显示屏300所在的平面)。
第二屏302包括边305、边306以及边307。虚拟显示屏901位于x轴、z轴所在平面。虚拟显示屏901可以设置在显示屏300侧边所在的垂直平面上，也即位于第二屏302的边305所在的垂直平面上。
在另一些实施例中，还包括虚拟显示屏902。虚拟显示屏902位于y轴、z轴所在平面。虚拟显示屏902可以设置在显示屏300顶端所在的垂直平面上，也即位于第二屏302的边306所在的垂直平面上。
在另一些实施例中，还包括虚拟显示屏903。虚拟显示屏903位于y轴、z轴所在平面。虚拟显示屏903可以设置在显示屏300底端所在的垂直平面上，也即位于第二屏302的边307所在的垂直平面上。
同理，可以在第一屏301附近布局虚拟显示屏，本申请对此不再赘述。
在本申请实施例中，终端设备200可以根据实际情况设置若干虚拟显示屏，本申请对此不作具体限定。
如上述，介绍了所创建的虚拟显示屏(901、902、903)与显示屏300的位置关系，基于虚拟显示屏布局在第二屏302的附近，虚拟显示屏901在隐藏显示空间的位置关系包括虚拟显示屏901位于第二屏302的边305所在的垂直平面上。相应地，虚拟显示屏902在隐藏显示空间的位置关系包括虚拟显示屏902位于第二屏302的边306所在的垂直平面上。虚拟显示屏903在隐藏显示空间的位置关系包括虚拟显示屏903位于第二屏302的边307所在的垂直平面上。虚拟显示屏(901、902、903)垂直于显示屏300。
可以理解，虚拟显示屏(901、902、903)为用户100不可见的，虚拟显示屏(901、902、903)并非真实地设置边305、边306以及边307所在的垂直平面上。终端设备200记录上述虚拟显示屏(901、902、903)与显示屏300的位置关系，以在后续显示各个虚拟显示屏(901、902、903)上的隐藏信息时，可以根据各个虚拟显示屏(901、902、903)与显示屏300的位置关系，显示对应的虚拟显示屏上的隐藏信息。也即，终端设备200创建虚拟显示屏时，需要保证虚拟显示屏(901、902、903)上的隐藏信息显示在显示屏300上时，该隐藏信息在显示屏300上所显示的位置关系与该隐藏信息对应的虚拟显示屏(901、902、903)与显示屏300之间的位置关系对应。
示例性地，虚拟显示屏901上显示有隐藏信息，则隐藏信息在显示屏300上的显示位置需要与第二屏302的边305附近的信息相邻，且该隐藏信息的显示效果为垂直于第二屏302上的内容。
需要指出的是，如果某一应用界面存在对应的虚拟显示屏来显示隐藏信息，则终端设备200只要进入该应用界面，该隐藏信息就始终存在，与终端设备200是否处于半展开状态还是展开状态无关。当图9中所示第一界面500为应用界面，图9示出了处于展开状态的终端设备200显示应用界面时的虚拟显示屏上所显示的隐藏信息，但是，对于展开状态的终端设备200，用户100无法查看到虚拟显示屏上的隐藏信息，因为此时用户100不能通过显示屏300看到隐藏信息，也即看不到隐藏显示空间内信息，而只能查看到显示屏300所在平面的信息(如第一界面)。
在一些实施例中，图9中所示的第一界面500可以为终端设备200的系统界面。相应地，当终端设备200存有隐藏信息，终端设备200只要进入系统界面，该隐藏信息就始终存在，与终端设备200是否处于半展开状态还是展开状态无关。
当然，空间隐藏信息也可以不和具体的应用界面或系统界面关联，而是系统级的空间，即在任 何界面唤出隐藏信息，均唤出相同的隐藏信息。
下面介绍添加隐藏信息到虚拟显示屏。
终端设备200可以预置有若干个虚拟显示屏(例如图9中所示的虚拟显示屏901、902、903)。
在一些实施例中，用户100调整虚拟显示屏的位置，如可以在x轴或y轴方向移动虚拟显示屏，以改变虚拟显示屏的位置，进而改变虚拟显示屏上的隐藏信息显示在显示屏300的位置。
当用户100想要添加隐藏信息时，如在某个应用界面或系统界面上添加隐藏信息，例如产生阅读感想、保存页面内的图片并不想被他人查看、对当前页面进行批注等，用户100可以通过特定操作(比如唤出隐藏控件并点击)来唤出虚拟显示屏，用户100可以选择一个虚拟显示屏来记录隐藏信息。在添加信息时，终端设备200可以处于展开状态，且用户100选择虚拟显示屏后，虚拟显示屏可以转化为显示屏300上等面积大小的区域，以方便用户的编辑。
虚拟显示屏转化为显示屏300上等面积大小的区域可以视为电子白板，用户可以在上面手写文字、将应用界面的文字/图片复制到该区域(虚拟显示屏)上，所添加的信息即为隐藏信息。
空间隐藏信息可以视为隐藏在垂直空间中的虚拟显示屏上显示的信息。若要观察到终端设备200上所存的隐藏信息，包括应用界面或系统界面或系统级对应的空间隐藏信息，终端设备200需要满足两个条件：第一、终端设备200处于半展开状态(终端设备200处于展开状态时不显示隐藏信息)；第二、终端设备200启动了隐藏信息显示功能。
下面介绍启动隐藏显示功能的第一操作。
第一操作用于启动隐藏信息显示功能。用来查看隐藏信息的第一操作可以是：显示屏300上的手势、对物理按键的操作、对虚拟按键的操作、显示屏300的折叠动作中的至少一种。举例来说，当应用界面存在空间隐藏信息时，可以在应用界面上悬浮显示一虚拟按键，用户100通过点击虚拟按键来查看空间隐藏信息。
在一些实施例中，当隐藏信息与应用界面内的特定内容相关联时，也可以响应用户100对应用界面上的该特定内容的操作来显示隐藏信息。例如，当隐藏信息为针对应用界面内的某个图片的注释时，若用户100点击该图片，或者用户100滑动界面至在显示屏300上显示该图片时，则触发该图片的注释信息的显示，即显示对应的隐藏信息。
在一些实施例中，终端设备200在半展开状态下检测到上述第一操作，则进入隐藏信息的显示。当终端设备200处于展开在状态，用户100执行上述第一操作(除了折叠操作外的其他操作)，由于展开状态无法观察到隐藏信息，因此无法在显示屏300上显示隐藏信息，可以不响应该第一操作。或者在检测到终端设备200处于半展开状态后，再通过显示屏300显示空间隐藏信息。
步骤S63：终端设备响应于接收到第一操作，判断是否存在隐藏信息。
在本申请实施例中，终端设备200接收到第一操作后，可以先确定是否存在隐藏信息。如果存在，则执行步骤S65。若不存在，则不响应该第一操作。其中，判断是否存在隐藏信息可以为判断当前第一界面500是否存在关联的隐藏信息，或者是判断终端设备200是否存在隐藏信息，而该隐藏信息没有与第一界面500关联。
在一些实施例中，步骤S63可以为：终端设备200响应于接收到第一操作，判断是否存在隐藏信息且判断终端设备200是否处于半展开状态。若存在隐藏信息且终端设备200处于半展开状态，则终端设备200执行步骤S65。若不存在隐藏信息且终端设备200不处于半展开状态，或，若不存在隐藏信息，终端设备200处于半展开状态，或，若存在隐藏信息，终端设备200不处于半展开状 态，则终端设备200执行步骤S64。
在一些实施例中，步骤S63可以删除，可以设置为只有存在隐藏信息时，终端设备200才可能接收到第一操作，也即第一操作的方式才可用。例如，当使用虚拟按键来触发显示隐藏信息时，若没有空间隐藏信息，则虚拟按键不可用，或直接不显示虚拟按键。
同理，终端设备200可以仅在检测到处于半展开状态时，终端设备200才可能接收到第一操作，也即第一操作的方式才可用。例如，当使用虚拟按键来触发显示隐藏信息时，若没有空间隐藏信息，则虚拟按键不可用，或直接不显示虚拟按键。
若否，步骤S64：终端设备不响应第一操作。
在本申请实施例中，终端设备200判断不存在隐藏信息，则不响应该第一操作，也即不显示隐藏信息。
在另一些实施例中，终端设备200判断不存在隐藏信息，但是存在虚拟显示屏，也可以响应该第一操作，参考下述步骤S65、S66以及S67，确定出第二显示区域以及隐藏显示区域，显示屏300的第二显示区域上显示第一界面，隐藏显示区域上无显示内容。
若是，步骤S65：终端设备响应于第一操作，根据终端设备的第一姿态确定第一界面的第二显示区域，其中第二显示区域是第一显示区域的部分区域，第一姿态指示显示屏处于半展开状态。
在本申请实施例中，当终端设备200接收到第一操作后，终端设备200处于半展开状态且存在隐藏信息，终端设备200响应第一操作，通过显示屏300显示隐藏信息。在终端设备200把隐藏信息显示在显示屏300上前，需要确定出用于显示隐藏信息的隐藏显示区域。
在一些实施例中，步骤S63、S64可以删除，步骤S65为：终端设备200响应于第一操作判断是否存在隐藏信息以及判断终端设备200是否处于半展开状态，若是，则终端设备200根据终端设备200的第一姿态确定第一界面的第二显示区域。若判断不存在隐藏信息、终端设备200处于半展开状态，或，若判断存在隐藏信息、终端设备200不处于半展开状态，或，若判断不存在隐藏信息且终端设备200不处于半展开状态，则结束流程。
在一些实施例中，若第一界面500未占满第一显示区域400，则可以从第一显示区域400中第一界面500未占的区域中确定出隐藏显示区域。
在另一些实施例中，可以对第一界面500进行处理，例如，对当前正在显示的第一界面500进行预设处理，缩小第一界面500的显示区域，如确定第一界面500的第二显示区域，以在显示屏300上空出额外的空闲显示区域，然后从空出的空闲显示区域中确定隐藏显示区域。
在本申请实施例中，在基于终端设备200的第一姿态在显示屏300上确定一隐藏显示区域，首先基于终端设备200的第一姿态对确定第一界面500的第二显示区域，第二显示区域相对于第一显示区域400减小，在显示屏300上划分出第二显示区域外的空闲显示区域。然后基于当前第二显示区域的边缘和隐藏信息在隐藏显示空间中的第一位置，在空闲显示区域中确定隐藏显示区域。
在本申请实施例中，处于展开状态下终端设备200显示的第一界面500为平面内容。由于半展开状态下终端设备200的两个分屏不在同一平面，因此在视觉上可以视为两个维度。如果再结合显示隐藏信息，则显示屏300上显示的维度过多，影响视觉效果。为了提高视觉效果，在确定第一界面500的第二显示区域时，可以通过预设处理将当前第一界面500进行3D化处理，使得两个分屏上的界面在视觉上处于同一平面上，也即处理后的第一界面500在视觉上为平面内容。这样，再结合隐藏显示空间上显示的隐藏信息，使得从视觉上看，在看见平面内容(第一界面)的同时，还看 见了隐藏显示空间上的虚拟显示屏的隐藏信息，且隐藏信息与第一界面500在显示屏300上呈现一种立体效果。
下面介绍3D化处理，请参阅图10，图10为本申请实施例提到另一种隐藏信息显示方法流程示意图。
步骤S101：响应于第一操作，确定基准面。
其中，基准面对应终端设备200处于展开状态时显示屏300所在的平面。如上述图8A所示的二维水平面801即基准面。在终端设备200处于半展开状态时，以其中一个分屏所在平面为水平面，显示屏300投影至该水平面的区域即基准面。如基准面与上述图8B所示的二维平面802平行。
在本申请实施例中，基准面与某一平面平行，可以理解为该平面即基准面，或者，基准面位于该平面上。
图11A至图11C，示意终端设备200处于展开状态下和半展开状态下，内折屏显示的第一界面。图12A至图12C，示意终端设备200处于展开状态下和半展开状态下，外折屏显示的第一界面。
如图11A和图12A所示，终端设备200处于展开状态。建立直角坐标系，以显示屏300侧端所在直线为x轴，显示屏300的顶端所在直线为y轴。z轴垂直于x轴和y轴所在的平面(也即显示屏300所在的平面)。显示屏300在第一显示区域400上显示第一界面500。其中，可以选择x、y轴所在平面为基准面，也即当前显示屏300所在的平面(x、y轴所在平面)平行基准面。
如图11B所示，朝内翻折显示屏300，第一屏301和第二屏302之间的夹角大于0°，终端设备200处于半展开状态，基准面平行第一屏301(x、y轴所在平面)所在平面。
如图12B所示，朝外翻折显示屏300，第一屏301和第二屏302之间的夹角大于0°，终端设备200处于半展开状态，基准面平行第一屏301(x、y轴所在平面)所在平面。
在本申请实施例中，终端设备200处于半展开状态，基准面平行显示屏300中的一个分屏(如第一屏301或第二屏302)所在平面。如图11B，基准面平行第一屏301所在的平面，也即图11A显示屏300所在平面。
步骤S102：根据终端设备的第一姿态确定最佳观看位置。
其中，终端设备200的第一姿态至少包括第一屏301和第二屏302之间夹角的角度。
在本申请实施例中，对于处于半展开状态的终端设备200，若要较好的观看到两个分屏上的内容，需要确定一个最佳观看位置。当第一屏301和第二屏302之间的夹角(即折叠角度)改变，最佳观看位置也随之改变。因此，最佳观看位置和终端设备200的姿态(折叠角度)具有对应关系。可以根据这种对应关系确定出最佳观看位置。例如，根据折叠角度和最佳观看位置的坐标之间的映射函数计算得到，或者预先存储折叠角度和最佳观看位置的坐标之间的对应表。
其中，折叠角度和最佳观看位置的坐标之间的映射函数以及折叠角度和最佳观看位置的坐标之间的对应表可以根据实际情况设置，在此不再赘述。
步骤S103：根据最佳观看位置确定基准面上显示第一界面的第一显示区域在显示屏上的投射界面。
其中，显示第一界面500的第一显示区域400即该第一显示区域400用于显示第一界面。
在一些实施例中，第一屏301和第二屏302分别显示不同的界面，第一界面500可以是某一分屏上的界面，如，基准面与第一屏301所在平面平行，则第一界面500为第二屏302上的界面。 基准面与第二屏302所在平面平行，则第一界面500为第一屏301上的界面。
在本申请实施例中，对于处于半展开状态的终端设备200，若要使得两个分屏上具有夹角的界面在视觉上呈现像是处于同一平面，只需要透过显示屏300“查看”到展开状态的显示屏300的屏幕即可。例如，将基准面上处于展开状态下的显示屏300沿着用户100(假设用户100处于最佳观看位置)的视线投射到当前状态下的显示屏300，就可以实现在当前状态下的显示屏300观看处于展开状态的显示屏300的屏幕的效果。
换句话说，有两个一样的终端设备200，其均相同的显示第一界面500。其中一个终端设备200处于展开状态，另一个处于半展开状态。将处于展开状态的终端设备200放置于处于半展开状态下的终端设备200的下方，以与处于半展开状态下的终端设备200的一个分屏平行。该与处于展开状态的终端设备200平行的分屏所在的平面与基准面平行。将处于半展开状态下的终端设备200的显示屏300视为透明窗口，可以看到处于展开状态下的终端设备200上显示的第一界面500。该处于展开状态下的终端设备200所在的平面即为基准面，将该处于展开状态下的终端设备200上显示的第一界面500的第一显示区域400沿着最佳观看位置的用户100的视线反向投射至处于半展开状态下的终端设备200上的显示屏300，得到投射界面。该投射界面即第一显示区域400的投射至显示屏300上的区域。
例如，图11A中处于展开状态的显示屏300上显示第一界面500的第一显示区域400。图11B中处于半展开状态的显示屏300上显示第一界面500的第一显示区域400。图11A的显示屏300的所在平面平行图11B的基准面，通过图11B的窗口(即显示屏300)查看图11A上显示屏300的屏幕内容，包括第一显示区域400，即可以得到视觉上的平面效果。沿着用户100处于最佳观看位置的视线方向的反向将图11A的界面投影到图11B的显示屏300上，即可在图11B的具有夹角的显示屏300得到平面效果的第一界面500，如图11C所示。图11A中第一屏301与图11B中第一屏301所在平面平行，则图11A中第一屏301上的内容投射至图11B中第一屏301上的内容没有变化，即第一屏301上的投射界面部分未发生畸形变化。图11A中第二屏302与图11B中第二屏302所在平面不平行，则图11A中第二屏302上的内容投射至图11B中第二屏302上的内容发生变化，即第二屏302上的投射界面部分发生畸形变化。图11C中第二屏302上投射界面部分的区域包括边111、边112、边113以及折叠边303围成的投影区域600。
例如，图12A中处于展开状态的显示屏300上显示第一界面500的第一显示区域400。图12B中处于半展开状态的显示屏300上显示第一界面500的第一显示区域400。图12A的显示屏300的所在平面平行图12B的基准面，通过图12B的窗口(即显示屏300)查看图12A上显示屏300的屏幕内容，包括第一显示区域400，即可以得到视觉上的平面效果。沿着用户100处于最佳观看位置的视线方向的反向将图12A的界面投影到图12B的显示屏300上，即可在图12B的具有夹角的显示屏300得到平面效果的第一界面500，如图12C所示。图12A中显示屏300与图12B中显示屏300所在平面不平行，则图12A中显示屏300上的内容投射至图12B中显示屏300上的内容发生变化，即显示屏300上的投射界面部分发生畸形变化。图12C中显示屏300上投射界面部分的区域包括边11、边12、边13以及边14围成的投影区域600，其中边11为第一屏301的侧边。
图11B和图12B为未3D化处理前，在显示屏300的屏幕上显示的第一界面500，图11C和图12C为经过3D化处理后，将处于展开状态下的终端设备400的第一界面500投影到处于半展开状态的终端设备200的显示屏300上显示的第一界面500。其中虚线对应在位于基准面平行的显示屏 300上所呈现的基准面上完全展开状态的屏幕边缘，也即投射界面。如图11C，投影区域600包括显示屏300上显示的边111、112以及113和折叠边303所围成的区域。如图12C，投影区域600包括显示屏300上的边11、边12、边13以及边14。
基于投射关系，可以直接确定投射界面在屏幕上的显示区域，在投射界面，用户可以看到完整的第一界面500的内容，但第一界面500内容会产生一定的畸变(如图11C和图12C所示的投影区域600)。将投射界面显示在屏幕上时，即完成了当前第一界面500的3D化显示。
步骤S104：根据投射界面确定显示第一界面的第二显示区域。
在本申请实施例中，根据投射界面确定显示第一界面500的第二显示区域，第一界面500的投射界面的区域即为第一界面500的第二显示区域。
如图11C，第一界面500的第二显示区域包括第一屏301上显示部分第一界面500的区域以及投影区域600。如图12C所示，第一界面500的第二显示区域即为投影区域600。图11C中第二显示区域中包括投射后未变化的区域即第一屏301上显示部分第一界面500的区域，也包括投射后变化的区域，也即第二屏302上显示的投影区域600。图11C中第二显示区域包括投射后变化的投影区域600。
步骤S66：终端设备根据第二显示区域与隐藏信息在第一显示区域上确定隐藏显示区域；其中，隐藏显示区域与第二显示区域不重叠。
在一些实施例中，隐藏显示区域的大小与显示屏300的折叠角度相关。
如上述，隐藏信息是显示在隐藏显示空间内的。显示屏300在终端设备200所处空间中的高度越高，用户100透过窗口能看见隐藏显示空间的体积就越多，就能看到越多的内容。假设虚拟显示屏固定于隐藏显示空间内一固定位置，则高度越高，能观察到越多虚拟显示屏上的内容。因此，隐藏显示区域(如图14B的隐藏显示区域146、147以及148，或者，图15B的隐藏显示区域157、158、159，或者，图15C的隐藏显示区域161、162、163)在显示屏300上所显示的面积大小与终端设备200的屏幕在空间中的高度呈正相关关系，高度越高，显示面积越大，也即隐藏显示区域就越大。
在一些实施例中，显示屏300在空间中的高度定义为终端设备200平稳的放置在x轴、y轴所在平面上时，显示屏300上的所有像素点到x轴、y轴所在平面的最大距离。
示例性地，请参阅图13A，以显示屏300朝内翻折为例，第二屏302的边缘到水平面800(也即第一屏301所在平面)的距离最大，则第二屏302的边缘到第一屏301所在平面的距离为显示屏300在终端设备200所处空间中的高度。
示例性地，请参阅图13B，以显示屏300朝外翻折为例，显示屏300放置在水平面800上时，第一屏301和第二屏(图未示)的边缘接触水平面，折叠线303在最高位置。因此，折叠线303与显示屏300的上、下边缘所在平面(也即水平面800)的距离为显示屏300在终端设备200所处空间中的高度。
由于显示屏300在终端设备200所处空间中的高度难以计算，且终端设备200的折叠角度直接影响显示屏300在终端设备200所处空间的高度，因此，可以转化为隐藏显示区域的大小与终端设备200的折叠角度相关，当终端设备200的折叠角度变化时，隐藏显示区域的显示面积随着折叠角度的变化而增大或减小。
在一些实施例中，当显示屏300为向内翻折时，随着第一屏301与第二屏302之间的夹角在 第一范围区间内逐渐变小，显示屏300在空间中的高度越高，隐藏显示区域逐渐变大；随着第一屏301与第二屏302之间的夹角在第二范围区间内逐渐变小，显示屏300在空间中的高度越低，隐藏显示区域逐渐变小，其中第一范围区间为[90°，180°)；第二范围区间为(0°，90°]。
具体地，对于内折屏，折叠角度(第一屏301和第二屏302的夹角)在[90°,180°]之间时，折叠角度越小，屏幕在z轴方向上的高度越高，隐藏显示区域的显示面积越大，反之越小。在折叠角度为90°时，隐藏显示区域显示面积最大；折叠角度为180°时，隐藏显示区域的显示面积最小。折叠角度为0°，无法看到隐藏显示区域。
在一些实施例中，当显示屏300为向外翻折时，随着第一屏301与第二屏302之间的夹角在第三范围区间内逐渐变小，隐藏显示区域逐渐变大，其中第三范围区间为(0°，180°)。
具体地，对于外折屏，第一屏301与第二屏302之间的夹角在[0°,180°]之间时，折叠角度越大，示屏300在空间中的高度越高，隐藏显示区域显示面积越大。折叠角度为0°时，隐藏显示区域的显示面积最大；折叠角度为180°时，隐藏显示区域的显示面积最小，无法看到隐藏显示区域。
在本申请实施例中，可以通过定义虚拟显示屏的大小，来定义隐藏显示区域的最大显示面积。在一些实施例中，当达到最大显示面积时，隐藏显示区域的大小不再随着继续折叠而变化。
在本申请实施例中，基于第一界面500的第二显示区域和虚拟显示屏在隐藏显示空间中的第一位置，在空闲显示区域(如第三显示区域700)中确定隐藏显示区域。由于投射界面产生了畸变，因此，投射界面不会占据完整的屏幕，投射界面之外的区域即为空闲显示区域，可以从空闲显示区域中确定隐藏显示区域。具体地，根据第一显示区域400和第二显示区域确定出第三显示区域700(如图11C和图12C所示，根据第二显示区域确定第三显示区域700)，然后在第三显示区域700内确定隐藏显示区域，第二显示区域和第三显示区域700组成第一显示区域400。
在一些实施例中，根据第二显示区域和隐藏信息在第一显示区域400上确定隐藏显示区域可以包括如下步骤：首先确定隐藏信息在隐藏显示空间的第一位置，然后根据第二显示区域与第一位置在第一显示区域400上确定隐藏显示区域。
其中，隐藏信息在隐藏显示空间的第一位置也即显示该隐藏信息的虚拟显示屏在隐藏显示空间的位置。虚拟显示屏在隐藏显示空间的位置对应这该虚拟显示屏与显示屏300之间的位置关系，也对应这该虚拟显示屏投影至显示屏300上的位置。
在本申请实施例中，基于要实现显示隐藏信息的视觉效果为：以显示屏300作为透明窗口，用户100透过窗口能够看到窗口背后的隐藏信息，该隐藏信息就像存在显示屏300背后的立体空间(也即隐藏显示空间)中。为此，需要依据隐藏信息在隐藏显示空间的第一位置，将隐藏信息投影至显示屏300，则根据第二显示区域与第一位置在第一显示区域400上确定隐藏显示区域。其中，根据第二显示区域与第一位置在第一显示区域400上确定隐藏显示区域，也即，根据第一位置在第一显示区域400上除了第二显示区域之外的区域(如第三显示区域700)上确定隐藏显示区域。
在一些实施例中，确定隐藏信息在隐藏显示空间的第一位置包括：确定隐藏信息所处的虚拟显示屏，其中虚拟显示屏垂直于第一屏301所在的平面；根据虚拟显示屏与第二屏302的关系确定第一位置，其中第一位置包括虚拟显示屏位于第二显示区域的上方、侧方或下方。
其中，确定隐藏信息所处的虚拟显示屏也即确定当前终端设备200所存在的隐藏信息是显示在哪个虚拟显示屏上的。根据虚拟显示屏与第二屏的关系确定第一位置。如图9所示，虚拟显示屏901位于第二屏302的边305所在的垂直平面上，由此可以确定虚拟显示屏902在显示屏300的显 示位置对应边305上。相应地，可以分别确定虚拟显示屏902和虚拟显示屏903在显示屏300的显示位置对应边306以及边307。
可以理解，若以第二屏302所在的平面为基准面，虚拟显示屏垂直与第二屏302所在的平面，则根据虚拟显示屏与第一屏301的关系确定第一位置。
在一些实施例中，根据第二显示区域与第一位置在第一显示区域400上确定隐藏显示区域包括：根据第二显示区域在第一显示区域400上确定第三显示区域，其中第三显示区域与第二显示区域构成第一显示区域400；根据预设比例缩放隐藏信息所处的虚拟显示屏，得到缩放后的虚拟显示屏；根据缩放后的虚拟显示屏确定第三显示区域上的隐藏显示区域。
具体地，隐藏显示区域可以由虚拟显示屏进行等比例缩放后得到。
如图14A所示，终端设备200处于展开状态，以显示屏300(即第二屏302)的边322为x轴，以第二屏302的边312所在直线为y轴，z轴垂直x、y轴所在平面，建立直角坐标系。终端设备200在y、z轴所在平面上设置虚拟显示屏143，虚拟显示屏143位于边312所在的垂直平面上。终端设备200在x、z轴所在平面上设置虚拟显示屏144，虚拟显示屏144位于边322所在的垂直平面上。终端设备200在y、z轴所在平面上设置虚拟显示屏145，虚拟显示屏144位于边332所在的垂直平面上。
若虚拟显示屏143、144、145上均显示有隐藏信息，则可以确定隐藏信息在隐藏显示空间的位置分别为虚拟显示屏143、144、145在隐藏显示空间的位置。也即对应虚拟显示屏143、144、145与显示屏300之间的位置关系，更具体地，是对应虚拟显示屏143、144、145与第二屏302之间的位置关系，如是位于第二屏302的哪个边上。在确定隐藏显示区域时，可以根据虚拟显示屏的宽度和相应投射界面(也即第二显示区域)的对应边长来确定缩放比例，将缩放后的虚拟显示屏与对应边长重合，即得到隐藏显示区域。如图14B所示，可以根据x、z轴所在平面的虚拟显示屏144与投射界面相交的边的宽度和相应投射界面(也即投影区域)的侧边来确定缩放比例，也即根据虚拟显示屏144的边的宽度和投影区域的边603确定缩放比例，进而可以确定如图14B虚拟显示屏144在显示屏300上的隐藏显示区域147。其中该隐藏显示区域147垂直于投影区域，且该隐藏显示区域与投影区域的边603相交。
同理，可以根据y、z轴所在平面的虚拟显示屏143与投射界面相交的边的宽度和相应投射界面(也即投影区域)的侧边来确定缩放比例，也即根据虚拟显示屏143的边的宽度和投影区域的边601确定缩放比例，进而可以确定如图14B虚拟显示屏143在显示屏300上的隐藏显示区域146。其中该隐藏显示区域146垂直于投影区域，且该隐藏显示区域与投影区域的边601相交。
同理，可以根据y、z轴所在平面的虚拟显示屏145与投射界面相交的边的宽度和相应投射界面(也即投影区域)的侧边来确定缩放比例，也即根据虚拟显示屏145的边的宽度和投影区域的边602确定缩放比例，进而可以确定如图14B虚拟显示屏145在显示屏300上的隐藏显示区域148。其中该隐藏显示区域148垂直于投影区域，且该隐藏显示区域与投影区域的边602相交。
因此，如图14B，在显示屏300上可以确定显示在虚拟显示屏143的隐藏信息所对应的隐藏显示区域位于投影区域(也即第二显示区域)的上方，显示在虚拟显示屏144的隐藏信息所对应的隐藏显示区域位于投影区域(也即第二显示区域)的侧方，显示在虚拟显示屏145的隐藏信息所对应的隐藏显示区域位于投影区域(也即第二显示区域)的下方。
当然，也可以根据其他参数来确定缩放比例。例如，可以预置折叠角度和缩放比例的对应关系， 然后直接根据折叠角度来确定。
在一些实施例中，根据第二显示区域与第一位置在第一显示区域400上确定隐藏显示区域包括：根据第二显示区域在第一显示区域400上确定第三显示区域，其中第三显示区域与第二显示区域构成第一显示区域400，将隐藏信息所处的虚拟显示屏沿着预设的第一视线(也即用户100位于最佳观看位置时所看到的显示屏200的视线)反向投影至第三显示区域，得到隐藏显示区域。
具体地，隐藏显示区域由虚拟显示屏沿着视线反向投影得到。处理器认为在与水平面不平行的上半分屏(如第二屏302)之后的立体空间中存在虚拟显示屏，在将基准面上完全展开的显示屏300沿着视线反向投影得到投射界面时，可以将虚拟显示屏的界面(上的像素点)一并投射到当前状态的显示屏300上。
如图15A所示，终端设备200处于展开状态，以显示屏300(即第二屏302)的边322为x轴，以第二屏302的边312所在直线为y轴，z轴垂直x、y轴所在平面，建立直角坐标系。终端设备200在y、z轴所在平面上设置虚拟显示屏151，虚拟显示屏151位于边312所在的垂直平面上。终端设备200在x、z轴所在平面上设置虚拟显示屏152，虚拟显示屏152位于边322所在的垂直平面上。终端设备200在y、z轴所在平面上设置虚拟显示屏153，虚拟显示屏153位于边332所在的垂直平面上。
若虚拟显示屏151、152、153上均显示有隐藏信息，则可以确定隐藏信息在隐藏显示空间的位置分别为虚拟显示屏151、152、153在隐藏显示空间的位置。也即对应虚拟显示屏151、152、153与显示屏300之间的位置关系，更具体地，是对应虚拟显示屏151、152、153与第二屏302之间的位置关系，如是位于第二屏302的哪个边上。
如图15B，用户100朝向纸面(第一屏301、302)，根据当前15B所示的第一屏301、302之间的夹角确定最佳观看位置，用户100位于最佳观看位置以第一视线查看显示屏300，虚拟显示屏151以第一视线的方向反向投射至显示屏300上，确定虚拟显示屏151在第二屏302的上投影区域为隐藏显示区域157。同理，将虚拟显示屏152以第一视线的方向反向投射至显示屏300上，确定虚拟显示屏152在第二屏302的上投影区域为隐藏显示区域158。将虚拟显示屏153以第一视线的方向反向投射至显示屏300上，确定虚拟显示屏153在第二屏302的上投影区域为隐藏显示区域159。
如图15C，用户100朝向纸面(第一屏301、302)，根据当前15C所示的第一屏301、302之间的夹角确定最佳观看位置，用户100位于该最佳观看位置以第一视线查看显示屏300，虚拟显示屏151以第一视线的方向反向投射至显示屏300上，确定虚拟显示屏151在第二屏302的上区域为隐藏显示区域161。同理，将虚拟显示屏152以第一视线的方向反向投射至显示屏300上，确定虚拟显示屏152在第二屏302的上区域为隐藏显示区域162。将虚拟显示屏153以第一视线的方向反向投射至显示屏300上，确定虚拟显示屏153在第二屏302的上区域为隐藏显示区域163。
如图15B，第一界面500的投影区域600在第二屏302上由边154、边155以及边156围成，边154、边155以及边156分别对应第二屏302的边312、332、以及322。隐藏显示区域157垂直投影区域600，且与投影区域的边154相交。隐藏显示区域158垂直投影区域，且与投影区域的边156相交。隐藏显示区域159垂直投影区域，且与投影区域的边155相交。也即可以确定隐藏显示区域157、158以及159分别位于投影区域(即第二显示区域)的上方、侧方和下方。
如图15C，第一界面500的投影区域600在第二屏302上由边154、边155以及边156围成， 边154、边155以及边156分别对应第二屏302的边312、332、以及322。隐藏显示区域161垂直投影区域600，且与投影区域的边154相交。隐藏显示区域162垂直投影区域，且与投影区域的边156相交。隐藏显示区域163垂直投影区域，且与投影区域的边155相交。也即可以确定隐藏显示区域161、162以及163分别位于投影区域(即第二显示区域)的上方、侧方和下方。
图14A至图14B所示的隐藏显示区域的方式与图15A至图15C所示隐藏显示区域的方式的区别在于，当采用投影方式得到隐藏显示区域，折叠角度小于一定值时，虚拟显示屏不能完全投影到显示屏300上，导致有部分虚拟显示屏上的隐藏信息查看不到，例如图15B中，隐藏显示区域157、158、159均只显示部分隐藏信息。仅有在折叠角度大于该值，虚拟显示屏能够完全投影时，才能查看到完整的显示内容。当采用缩放的方式时，则隐藏信息均能够完整的显示，只要缩放后的清晰度满足人眼能够看清即可。
在投影和缩放时，可以将虚拟显示屏上的内容一并进行投影/缩放，从而实现内容的显示。
步骤S67：终端设备在第二显示区域上显示第一界面，在隐藏显示区域上显示隐藏信息。
在本申请实施例中，如图14B，在第二显示区域上显示第一界面500，在隐藏显示区域146、147、148上显示隐藏信息。如图15B，在第二显示区域上显示第一界面，在隐藏显示区域157、158、159上显示隐藏信息。如图15C，在第二显示区域上显示第一界面，在隐藏显示区域161、162、163上显示隐藏信息。
在一种可能的设计方式中，隐藏显示区域包括相交的第一边与第二边，第二显示区域包括相交的第三边与第四边，第一边与第三边重合，第二边与第三边垂直，第二边与第四边垂直。如图14B，隐藏显示区域146的第一边与投影区域600的第三边重合，隐藏显示区域147的第二边与隐藏显示区域146的第二边重合，隐藏显示区域147的第一边与投影区域600的第四边重合。隐藏显示区域146的第二边与投影区域600的第三边、第四边均垂直，隐藏显示区域147的第二边与投影区域600的第三边、第四边均垂直。
在本申请实施例中，终端设备200除了在显示屏300上显示显性内容外，还在垂直于显示屏300所在平面的空间中隐藏显示有隐藏内容，在满足终端设备200为半展开状态的情况下，通过指向显示隐藏内容的预设操作，对当前应用界面(显性内容)进行3D化处理，同时将隐藏内容显示在显示屏300上。通过利用垂直空间来显示隐藏信息，并通过折叠到半展开状态来显示空间隐藏信息，实现了利用终端设备200的折叠来实现信息的隐藏，增强了折叠的交互，突出了终端设备200的优势。通过利用垂直空间来显示隐藏信息，具有利用空间来隐藏的体验，让用户有一种信息隐藏在屏幕背后的空间中的真实感，实现一种空间层面的交互体验。通过空间隐藏信息和应用界面的对应关系，可以实现对当前界面的批注/感想，且只有用户知晓该批注信息，增强了隐私的同时，又能够将批注信息/感想直接和当前页面关联，方便用户的调用和联想。
在本申请实施例中，空间隐藏信息虚拟的显示在垂直于完全展开状态下屏幕所在平面的虚拟显示屏300上，虚拟显示屏相对完全展开状态下屏幕的位置由系统预置。
在本申请实施例中，虚拟显示屏垂直于完全展开状态的屏幕所在屏幕，且屏幕的边缘线为虚拟显示屏所在平面与基准面的交界线。
在本申请实施例中，隐藏显示区域由虚拟显示屏进行等比例缩放后得到。
在本申请实施例中，隐藏显示区域由虚拟显示屏沿着视线反向投影得到。
在本申请实施例中，隐藏显示区域的大小与终端设备200的折叠角度相关，当终端设备200的 折叠角度变化时，隐藏显示区域的显示面积随着折叠角度的变化而增大或减小。
