 附图说明
为了更清楚地说明本申请实施例的技术方案，下面将对本申请实施例中所需要使用的附图作简单地介绍。显而易见地，下面所描述的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图4是本申请实施例提供的一种控制显示屏的装置的结构示意图；
图5是本申请实施例提供的一种智能终端的硬件结构示意图。
具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，如果不冲突，本申请实施例中的各个特征可以相互结合，均在本申请的保护范围之内。另外，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。再者，本申请所采用的“第一”“第二”“第三”等字样并不对数据和执行次序进行限定，仅是对功能和作用基本相同的相同项或相似项进行区分。
一般地，对于具有多操作系统的智能终端来说，其上运行的多个操作系统（包括主操作系统和若干客户操作系统）均共享同一显示屏，各操作系统通过操作智能终端中用于控制显示屏的相关接口（比如，智能终端的帧缓存设备的IOCTL接口、API接口等）来点亮或者熄灭该显示屏。其中，主操作系统可以直接操作所述用于控制显示屏的相关接口，而客户操作系统则需通过其内核中运行着的与显示控制相关的驱动程序操作所述用于控制显示屏的相关接口。然而，由于主操作系统和客户操作系统对显示屏的控制均在内核层实现，若多个操作系统同时操作所述用于控制显示屏的相关接口，并且，为异步操作（即，其中一个操作系统指示智能终端点亮显示屏，而另一个操作系统指示智能终端熄灭显示屏），则会导致显示屏的显示状态混乱。
基于此，本申请实施例提供了一种控制显示屏的方法、一种控制显示屏的装置、一种智能终端、一种非暂态计算机可读存储介质以及一种计算机程序产品。
其中，本申请实施例提供的控制显示屏的方法是一种能够在主操作系统的应用层实现客户操作系统对显示屏的控制的方法，具体为：当检测到客户操作系统接收到用于指示其点亮或者熄灭智能终端的显示屏的第一控制请求时，将所述第一控制请求转换为第一控制事件，并将所述第一控制事件输入主操作系统，以使所述主操作系统根据所述第一控制事件点亮或者熄灭所述显示屏。其中，在本申请实施例中，所述“第一控制事件”为主操作系统在应用层接收到的其中一种控制事件，该控制事件用于控制主操作系统操作智能终端中用于控制显示屏的相关接口，进而点亮或者熄灭显示屏。由于在本申请实施例中，客户操作系统对显示屏的控制通过主操作系统的应用层实现，因此，一方面，能够避免多个操作系统同时在内核层操作智能终端中用于控制显示屏的相关接口的情况，从而有效解决多个操作系统同时控制显示屏时有可能会造成显示状态混乱的问题；另一方面，无需在内核层为每一客户操作系统配置用于控制显示屏的相关接口，从而提升客户操作系统的可移植性，方便更换系统。
其中，本申请实施例提供的控制显示屏的装置是由软件程序构成的能够实现本申请实施例提供的控制显示屏的方法的虚拟装置，其与本申请实施例提供的控制显示屏的方法基于相同的发明构思，具有相同的技术特征以及有益效果。
其中，本申请实施例提供的智能终端可以是任意类型的电子设备，比如：机器人、智能手机、个人电脑、平板电脑、可穿戴智能设备、智能家电等等。该智能终端包括主操作系统和若干客户操作系统，能够执行本申请实施例提供的控制显示屏的方法，或者，运行本申请实施例提供的控制显示屏的装置。
具体地，下面结合附图，对本申请实施例作进一步阐述。
图1是本申请实施例提供的控制显示屏的方法的其中一种应用环境的示意图。该应用环境可以是运行在某一智能终端上的计算机系统环境。具体地，如图1所示，该应用环境中包括：物理硬件设备10、主操作系统11以及若干个客户操作系统12。
其中，物理硬件设备10是实际存在的硬件设备，可以包括任何合适的，组成完整计算机系统的设备组件，包括但不限于：处理器101、存储器102、输入设备103、通信模组104以及显示屏105等。
具体地，处理器101可以是任何合适类型的，具有一定逻辑运算能力的处理器，例如：CPU、图形处理器等。处理器101还可以包括用于多线程或并行处理的多个核心。
存储器102可以包括内存模块，例如：ROM、RAM、闪存模块，以及大容量存储器，例如光盘和硬盘。存储器102中存储有计算机程序，当处理器101执行这些计算机程序时，可以实现各种相应方法步骤或流程。
输入设备103可以是任何合适类型的，提供一种或者多种用户交互方式的外围设备，例如：接收用户动作操作指令的鼠标、键盘或者触摸输入屏，用于采集图像信息的体感摄像机或者用于采集声音信息的麦克风等。所述输入设备103可以选择使用有线或者无线的外围设备与其他物理硬件设备连接。
通信模组104可以包括某些通过有线或者无线通信网络建立连接的网络接口设备。例如，网线接口、总线接口、USB接口、WiFi模组或者蓝牙通信模组等。
显示屏105可以是任意类型的显示器，比如：液晶显示器、OLED显示器、LED显示器、量子点显示器、电泳显示器等等。其与处理器101通信连接，能够接收处理器101发送的控制指令，并根据该控制指令进行相关的显示操作，比如，点亮显示屏、熄灭显示屏等。
在实际应用过程中，所述物理硬件设备10还可以添加或者减省一个或者多个设备，用以满足不同的实际应用情况需求，例如增加数据库、服务器设备或者其他类型的输出设备。
其中，主操作系统11和客户操作系统12均属于管理和控制物理硬件设备10以及相应的软件资源的计算机程序，是直接运行在“裸机”上的最基本的系统软件，任何其他软件都必须在主操作系统11或客户操作系统12的支持下才能运行。在本申请实施例中，主操作系统11和客户操作系统12均可以是任何合适类型的操作系统，如：Linux、Unix、IOS、Android、Windows等，用以接收用户指令并据此输出对应的处理结果向用户展示。
主操作系统11以及若干个客户操作系统12之间共享所述物理硬件设备10。在实际运行时，主操作系统11可以直接使用所述物理硬件设备10中的硬件设备，而客户操作系统12则使用由驱动该客户操作系统12的虚拟机提供的虚拟设备。其中，所述“虚拟机”是指通过软件模拟的具有完整硬件系统功能的，运行在一个完全隔离环境中的计算机系统。所述虚拟机可以基于物理硬件设备10或者软件程序形成多个模拟出来的硬件设备（即，虚拟设备）供客户操作系统使用。一个虚拟机对应驱动一个客户操作系统12，每一所述虚拟机可以作为主操作系统11中的其中一个应用程序运行。
不同的操作系统之间存在有内存隔离，即便是主操作系统11也不能够访问客户操作系统12的内存空间。这样，当计算机系统中存在两个或以上的客户操作系统12时，若其中一个客户操作系统12因为异常重新启动，主操作系统11和其它客户操作系统12还可以正常运行，相互隔离。然而，由于虚拟机是作为主操作系统11中的应用程序运行的，因此，若主操作系统11因为异常重新启动，那么所有的客户操作系统12都需要重新启动才可以运行，同理，若主操作系统11被挂起，所有的客户操作系统12也都会被挂起。
在用户使用该智能终端时，在所有操作系统中（包括主操作系统11和所有客户操作系统12），仅有一个操作系统在前台运行，而其他操作系统则在后台运行或者休眠。比如，若在前台运行的操作系统为主操作系统11，则，所有客户操作系统12处于后台运行状态或者休眠状态；若在前台运行的操作系统为其中一个客户操作系统12，则，主操作系统11处于后台运行状态，其他客户操作系统12处于后台运行状态或者休眠状态。
在本申请实施例中，主操作系统11和所有在前台或者后台运行的客户操作系统12都可以接收用于控制显示屏105的显示状态的控制请求。其中，在本申请实施例中，将客户操作系统12接收到的控制请求称为“第一控制请求”，将主操作系统11接收到的控制请求称为“第二控制请求”。该“第一控制请求”包括用于指示对应的客户操作系统12点亮显示屏105的“第一唤醒请求”和用于指示对应的客户操作系统12熄灭显示屏105的“第一休眠请求”；该“第二控制请求”包括用于指示主操作系统11点亮显示屏105的“第二唤醒请求”和用于指示主操作系统11熄灭显示屏105的“第二休眠请求”。
特别地，在本实施例中，当智能终端检测到某一客户操作系统12接收到第一控制请求时，可以采用本申实施例提供的控制显示屏的方法来控制显示屏105的显示状态，具体为，当检测到客户操作系统12接收到第一控制请求时，将所述第一控制请求转换为第一控制事件，并将所述第一控制事件输入主操作系统11，以使所述主操作系统11根据所述第一控制事件点亮或者熄灭所述显示屏105。其中，所述“第一控制事件”是主操作系统11在其应用层接收到的其中一种输入事件，主操作系统11能够根据该第一控制事件操作智能终端中用于控制显示屏105的相关接口，进而点亮显示屏105。
其中，对应不同类型的第一控制请求，所述第一控制事件包括第一唤醒事件和第一休眠事件。具体为，当所述第一控制请求为第一唤醒请求时，对应将该第一唤醒请求转换为第一唤醒事件，当所述第一控制请求为第一休眠请求时，则将该第一休眠请求转换为第一休眠事件。所述第一唤醒事件用于控制主操作系统11点亮显示屏105，所述第一休眠事件则用于控制主操作系统11熄灭显示屏105。
其中，需要说明的是，本申请实施例提供的控制显示屏的方法还可以进一步的拓展到其他合适的应用环境中，而不限于图1中所示的应用环境。在实际应用过程中，该应用环境还可以包括更多或者更少的客户操作系统以及更多或者更少物理硬件设备类型。
图2是本申请实施例提供的一种控制显示屏的方法的流程示意图，该方法可以由智能手机、机器人、个人电脑、可穿戴智能设备、智能家电等包括主操作系统和若干客户操作系统的智能终端执行。
具体地，请参阅图2，该方法可以包括但不限于如下步骤：
步骤110：检测客户操作系统接收到的第一控制请求。
在本实施例中，所述“控制请求”可以是任意能够指示智能终端点亮或者熄灭其显示屏的指令。其可以包括唤醒请求和休眠请求，所述唤醒请求用于指示智能终端点亮其显示屏，所述休眠请求用于指示智能终端熄灭其显示屏。
该控制请求可以在用户对智能终端进行相关操作时触发产生，比如：当用户在显示屏熄屏状态下按下智能终端的电源键，或者，在包括触摸屏的显示屏上输入特定的手势操作，或者，输入点亮显示屏的语音指令时，触发产生所述唤醒请求，点亮显示屏；当用户在显示屏亮屏状态下按下智能终端的电源键或者输入关闭显示屏的指令时，触发产生所述休眠请求，熄灭显示屏。
或者，该控制请求也可以由正在运行的操作系统（包括主操作系统和客户操作系统）在满足某些预设条件的情况下自动触发，比如，当某一操作系统接收到来电、接收到即时消息、接收到通知提醒、检测到人脸图像或者检测到用户翻转的动作时，触发产生所述唤醒请求，点亮显示屏；当在前台运行的操作系在预设时间内没有接收到用户的交互信号时，触发产生所述休眠请求，熄灭显示屏。
其中，在本实施例中，将客户操作系统接收到的控制请求称为“第一控制请求”，用于指示该客户操作系统点亮或者熄灭智能终端的显示屏。该第一控制请求包括用于指示该客户操作系统点亮智能终端的显示屏的第一唤醒请求，以及，用于指示该客户操作系统熄灭智能终端的显示屏的第一休眠请求。
具体地，在本实施例中，支持客户操作系统运行的虚拟机中配置有用于控制显示屏的虚拟帧缓存设备，每一客户操作系统可以通过其对应的虚拟帧缓存接收所述第一控制请求。从而，所述检测客户操作系统接收到的第一控制请求，即，智能终端检测客户操作系统对应的虚拟帧缓存设备接收到的第一控制请求。
步骤120：将所述第一控制请求转换为第一控制事件，并将所述第一控制事件输入主操作系统，以使所述主操作系统根据所述第一控制事件点亮或者熄灭所述显示屏。
在本实施例中，所述“第一控制事件”是其中一种用于指示主操作系统点亮或者熄灭显示屏的控制事件，其中，所述控制事件为主操作系统在应用层接收到的一种输入事件。所述将所述第一控制请求转换为第一控制事件，即，将客户操作系统接收到的第一控制请求转换为能够被主操作系统的应用层识别和接收的第一控制事件。将该第一控制事件输入主操作系统后，可以使主操作系统根据该第一控制事件操作智能终端中用于控制显示屏的相关接口，点亮或者熄灭显示屏。
其中，当客户操作系统接收到的第一控制请求为第一唤醒请求时，将该第一唤醒请求转换为第一唤醒事件，并将该第一唤醒事件输入主操作系统，以使主操作系统根据该第一唤醒事件点亮智能终端的显示屏；当客户操作系统接收到的第一控制请求为第一休眠请求时，则将该第一休眠请求转换为第一休眠事件，并将该第一休眠事件输入主操作系统，以使主操作系统根据该第一休眠事件熄灭智能终端的显示屏。
具体地，在本实施例中，主操作系统设置有用于响应和处理输入事件的输入服务单元，以及，用于控制智能终端中各物理硬件（包括显示屏）的电源状态的电源管理服务单元。当客户操作系统对应的虚拟帧缓存设备接收到所述第一控制请求时，可以首先将该第一控制请求转换为能够被主操作系统的输入服务单元识别的第一控制事件，然后与主操作系统的输入服务单元进行通信，将该第一控制事件输入主操作系统；而主操作系统的输入服务单元在接收到该第一控制事件后，则可以采用常规的方法根据该第一控制事件点亮或者熄灭该智能终端的显示屏，具体为，根据接收到的第一控制事件将主操作系统的电源管理服务单元中显示屏的电源状态设置为唤醒状态或者休眠状态，进而根据电源管理服务单元中显示屏的电源状态操作智能终端中用于控制显示屏的相关接口以点亮或者熄灭其显示屏。
其中，需要说明的是，在实际应用中，若当前智能终端的显示屏为亮屏状态，则，当主操作系统接收到第一唤醒事件时，维持显示屏当前的亮屏状态不变；当主操作系统接收到第一休眠事件时，操作智能终端中用于控制显示屏的相关接口熄灭显示屏。若当前智能终端的显示屏为熄屏状态，则，当主操作系统接收到第一唤醒事件时，操作智能终端中用于控制显示屏的相关接口点亮显示屏；当主操作系统接收到第一休眠事件时，维持显示屏当前的熄屏状态不变。
此外，在本实施例中，当检测到主操作系统接收到用于指示其点亮或者熄灭智能终端的显示屏的第二控制请求时，该第二控制请求即主操作系统接收到的第二控制事件，从而，无论主操作系统当前是在前台运行还是在后台运行，都可以直接根据该第二控制请求操作智能终端中用于控制显示屏的相关接口点亮或者熄灭显示屏。同样地，该第二控制请求也可以包括用于指示主操作系统点亮智能终端的显示屏的第二唤醒请求和用于指示主操作系统熄灭智能终端的第二休眠请求；当主操作系统接收到所述第二唤醒请求时，直接根据该第二唤醒请求点亮所述显示屏；当主操作系统接收到所述第二休眠请求时，直接根据该第二休眠请求熄灭显示屏。
通过上述技术方案可知，在本实施例中，将客户操作系统接收到的第一控制请求转换为能够被主操作系统识别和接收的第一控制事件，该第一控制事件与主操作系统接收到的第二控制请求均属于主操作系统在其应用层接收到的输入事件，从而，在本实施例中，只需由主操作系统根据接收到的输入事件操作智能终端中用于控制显示屏的相关接口，即可实现点亮或者熄灭显示屏，避免了多个操作系统同时操作智能终端中用于控制显示屏的相关接口的情况，从而有效解决多个操作系统同时控制显示屏时有可能会造成显示状态混乱的问题；此外，通过在主操作系统的应用层实现客户操作系统对显示屏的控制，还可以提升客户操作系统的可移植性，方便更换系统。
进一步地，由于在单位时间内，只有在前台运行的操作系统才能够调用智能终端的物理输入设备与用户进行交互。因此，在一些实施例中，为了减少资源的消耗，各客户操作系统在切换到前台运行时，其对应的显示窗口为显示状态，而切换到后台运行时，其对应的显示窗口为隐藏状态；主操作系统仅将处于显示状态的显示窗口中的图像数据显示。比如，若在前台运行的是主操作系统，则，主操作系统对应的显示窗口可以通过显示屏呈现给用户，而所有在后台运行的客户操作系统对应的显示窗口皆为隐藏状态；若在前台运行的是其中一个客户操作系统，则，该处于前台运行状态的客户操作系统对应的显示窗口可以通过显示屏呈现给用户，而主操作系统以及其他在后台运行的客户操作系统对应的显示窗口均为隐藏状态。
由此，在该实施例中，在后台运行的客户操作系统对应的显示窗口是隐藏的，并且，用户也无法与在后台运行的客户操作系统进行交互，若同样对在后台运行的客户操作系统接收到的第一控制请求执行上述步骤120，点亮或者熄灭显示屏，会浪费智能终端的能耗。
基于此，本申请实施例还提供了另一种控制显示屏的方法。具体地，请参阅图3，该方法可以包括但不限于以下步骤：
步骤210：检测客户操作系统接收到的第一控制请求。
步骤220：确定接收到所述第一控制请求的客户操作系统的运行状态。
在本实施例中，所述“运行状态”可以包括前台运行状态、后台运行状态和休眠状态，所述前台运行状态表示操作系统在前台运行，所述后台运行状态表示操作系统在后台运行，所述休眠状态表示操作系统休眠。在所有操作系统中，只有一个操作系统处于前台运行状态，而其他已启动的操作系统均处于后台运行状态，未启动的操作系统则处于休眠状态。其中，由于处于休眠状态的客户操作系统没有运行中的进程也没有跟用户交互的界面，一般不会接收到所述第一控制请求，因此，在本实施例中，主要针对处于前台运行状态或者后台运行状态的操作系统进行讨论。其中，处于前台运行状态的操作系统对应的显示窗口为显示状态，以便于用户与该操作系统进行交互；而处于后台运行状态的操作系统对应的显示窗口为隐藏状态，以避免空转，节省智能终端的资源。
具体地，在本实施例中，当检测到客户操作系统接收到第一控制请求时（比如，某一客户操作系统在某一时刻接收到一条通知提醒，该通知提醒可以触发产生一个用于指示该客户操作系统点亮智能终端的显示屏的第一唤醒请求），首先确定所述客户操作系统的运行状态。
其中，在一些实施例中，确定接收到所述第一控制请求的客户操作系统的运行状态的具体实施方式可以是：
在主操作系统中提供一个状态锁服务，当客户操作系统切换至前台运行时向主操作系统申请状态锁，而当客户操作系统切换至后台运行或者进入休眠状态时向主操作系统撤销状态锁，从而，通过查询主操作系统中维护的状态锁服务列表即可确定接收到所述第一控制请求的客户操作系统的运行状态。
或者，在另一些实施例中，确定接收到所述第一控制请求的客户操作系统的运行状态的具体实施方式也可以是：
每一个客户操作系统均维护一个对应的状态记录表，用于记录该客户操作系统的运行状态。比如，若某一客户操作系统切换至前台运行，则更新其状态记录表为“前台运行状态”，若该客户操作系统切换至后台运行，则更新其状态记录表为“后台运行状态”，若该客户操作系统被挂起，则更新其状态记录表为“休眠状态”。从而，通过查询接收到该第一控制请求的客户操作系统对应的状态记录表即可确定该客户操作系统的运行状态。
具体地，支持客户操作系统运行的虚拟机中还配置有虚拟的系统切换设备，用于切换对应的客户操作系统的运行状态。当该虚拟的系统切换设备将其对应的客户操作系统由后台运行切换至前台运行，或者由前台运行切换至后台运行时，与其虚拟帧缓存设备通信，通知其虚拟帧缓存设备该客户操作系统当前的运行状态，其虚拟帧缓存设备根据所确定的运行状态更新该客户操作系统对应的状态记录表。在该实施例中，通过使每一客户操作系统都维护一个状态记录表，能够更加快速地确定每一操作系统的运行状态，同时，降低出错率。
进一步地，在本实施例中，若通过本步骤220确定接收到该第一唤醒请求的客户操作系统的运行状态为前台运行状态，则执行下述步骤230；若确定接收到该第一控制请求的客户操作系统的运行状态为后台运行状态（或者，休眠状态），则执行下述步骤240。
步骤230：将所述第一控制请求转换为第一控制事件，并将所述第一控制事件输入主操作系统，以使所述主操作系统根据所述第一控制事件点亮或者熄灭所述显示屏。
步骤240：丢弃所述第一控制请求。
在本实施例中，在确定接收到所述第一控制请求的客户操作系统的运行状态为后台运行状态（或者，休眠状态）后，丢弃该第一控制请求，不对该第一控制请求作出响应（即，不将该第一控制请求转换为第一控制事件输入主操作系统），从而可以降低智能终端的能量损耗。
其中，在一些实施例中，为了进一步降低客户操作系统控制显示屏时的出错率，可以在客户操作系统由前台运行状态切换至后台运行状态时，断开该客户操作系统对应的虚拟帧缓存设备与主操作系统的输入服务单元之间的通信连接；在客户操作系统由后台运行状态切换至前台运行状态时，建立该客户操作系统对应的虚拟帧缓存设备与主操作系统的输入服务单元之间的通信连接。
其中，需要说明的是，在本实施例中，当确定接收到的第一控制请求的客户操作系统的运行状态为后台运行状态后，丢弃该第一控制请求，仅为本实施例提供的其中一种实施方式，并不用于限定本申请实施例。在其他的一些实施方式中，当确定接收到的第一控制请求的客户操作系统的运行状态为后台运行状态后，也可以先判断该第一控制请求的优先级，若优先级较高，则执行上述步骤230，同时，将该客户操作系统切换至前台运行状态。
比如，用户设定某一客户操作系统A在后台进行某一项运算，当该项运算得到计算结果时，触发第一唤醒请求a，且该第一唤醒请求a的优先级较高；那么，当该项运算结束，得到计算结果时，智能终端可以检测到该客户操作系统A接收到该第一唤醒请求a，此时，即便该客户操作系统A处于后台运行状态，也可以执行上述步骤230，同时，智能终端还将该客户操作系统A切换至前台运行，此时，客户操作系统A对应的显示窗口为显示状态，从而方便用户及时地在显示屏上看到该项运算的计算结果。
此外，还需说明的是，上述步骤210和230分别与如图2所示的控制显示屏的方法中的步骤110和120具有相同的技术特征，因此，其具体实施方式可以参考上述实施例的步骤110和120中相应的描述，在本实施例中便不再赘述。
通过上述技术方案可知，本实施例提供的控制显示屏的方法通过在将接收到的第一控制请求转换为第一控制事件之前，首先判断接收到该第一控制请求的客户操作系统的运行状态，如果该客户操作系统的运行状态为前台运行状态，才将该第一控制请求转换为第一控制事件，并将该第一控制事件输入主操作系统，以使主操作系统根据该第一控制事件点亮或者熄灭显示屏，能够降低智能终端的能量损耗。
图4是本申请实施例提供的一种控制显示屏的装置的结构示意图，该装置40可以运行在任意包括主操作系统和若干客户操作系统的智能终端上，能够实现上述实施例提供的控制显示屏的方法。
具体地，请参阅图4，该装置40可以包括但不限于：第一检测单元41和第一控制单元42。
具体地，第一检测单元41用于检测客户操作系统接收到的第一控制请求，所述第一控制请求用于指示所述客户操作系统点亮或者熄灭智能终端的显示屏。第一控制单元42用于将所述第一控制请求转换为第一控制事件，并将所述第一控制事件输入主操作系统，以使所述主操作系统根据所述第一控制事件点亮或者熄灭所述显示屏。
在本实施例中，当第一检测单元41检测到某一客户操作系统接收到用于指示该客户操作系统点亮或者熄灭智能终端的显示屏的第一控制请求时，通过第一控制单元42将所述第一控制请求转换为第一控制事件，并将所述第一控制事件输入所述主操作系统，以使所述主操作系统根据所述第一控制事件点亮或者熄灭所述显示屏。
其中，在一些实施例中，只有在前台运行的客户操作系统对应的显示窗口是显示的，而在后台运行的客户操作系统对应的显示窗口是隐藏的；并且，在后台运行的客户操作系统也无法调用物理输入设备与用户进行交互。因此，在该实施例中，为了减少智能终端不必要的能量损耗，该装置40还包括：状态确定单元43。
该状态确定单元43用于确定接收到所述第一控制请求的客户操作系统的运行状态。其中所述运行状态包括前台运行状态和后台运行状态。若该状态确定单元42确定接收到所述第一控制请求的客户操作系统的运行状态为所述前台运行状态，则由第一控制单元42将所述第一控制请求转换为第一控制事件，并将所述第一控制事件输入所述主操作系统。
其中，在一些实施例中，智能终端中的客户操作系统均维护有一个对应的状态记录表，则，该状态确定单元43具体用于：通过查询接收到所述第一控制请求的客户操作系统对应的状态记录表确定所述客户操作系统的运行状态。
进一步地，在一些实施例中，该装置40还包括丢弃单元44。
若状态确定单元43确定接收到所述第一控制请求的客户操作系统的运行状态为所述后台运行状态，则通过该丢弃单元44丢弃所述第一控制请求。
再者，在又一些实施例中，装置40还包括：第二检测单元45和第二控制单元46。
第二检测单元45用于检测主操作系统接收到的第二控制请求，所述第二控制请求用于指示所述主操作系统点亮或熄灭所述显示屏；
第二控制单元46用于根据所述第二控制请求点亮或熄灭所述显示屏。
其中，需要说明的是，由于所述控制显示屏的装置与上述方法实施例中的控制显示屏的方法基于相同的发明构思，因此，上述方法实施例的相应内容以及有益效果同样适用于本装置实施例，此处不再详述。
通过上述技术方案可知，本申请实施例的有益效果在于：本申请实施例提供的控制显示屏的装置通过第一控制单元42将客户操作系统接收到的用于指示该客户操作系统点亮或者熄灭智能终端的显示屏的第一控制请求转换为第一控制事件，并输入主操作系统，使主操作系统根据该第一控制事件点亮或者熄灭所述显示屏，能够使客户操作系统对显示屏的控制在主操作系统的应用层实现，避免了多个操作系统同时操作智能终端中用于控制显示屏的相关接口的情况，从而有效解决多个操作系统同时控制显示屏时有可能会造成显示状态混乱的问题；此外，通过在主操作系统的应用层实现客户操作系统对显示屏的控制，还可以提升客户操作系统的可移植性，方便更换系统。
