下面以STR待机状态为例，对显示设备从开机状态进入STR待机状态的流程和显示设备从STR待机状态进入开机状态的流程进行说明：
示例性的，用户可通过按压控制装置上的电源键向处于开机状态的显示设备输入待机指令，显示设备接收到该待机指令后，将硬件运行状态信息存储到内存(例如RAM)中，释放正在使用的硬件资源(例如显示器、硬盘、外部设备等)并冻结进程；PM模块控制电源电路将除RAM和MCU以外的其他硬件进行掉电，也即控制电源电路仅需保持对RAM和MCU的供电；以及发送关屏 广播以使显示器关屏。至此，显示设备进入STR待机状态。显示设备处于STR待机状态时可以降低整机功耗。
进一步，示例性的，用户可通过按压控制装置上的电源键向处于STR待机状态的显示设备输入待机至开机的电源启动指令，当显示设备接收到该电源启动指令时，从内存中读取硬件运行状态信息，基于读取到的硬件运行状态信息进行硬件初始化；PM模块控制电源电路为各硬件供电，并启动操作***程序恢复至挂起前的状态；以及发送亮屏广播使得显示器亮屏。至此，显示设备进入开机状态。通过上述处理，可以节省显示设备从待机状态进入开机状态的等待时间，提高开机速度。
再示例性的，用户可通过按压控制装置上的快捷键向处于STR待机状态的显示设备输入快捷应用启动指令，显示设备接收到该快捷应用启动指令后进入STR开机流程，待开机之后启动快捷应用，并显示快捷应用提供的图形用户界面，例如，如图2所示，为快捷应用提供的图形用户界面200A的示意图。
至此，完成对显示设备从开机状态进入STR待机状态的流程和显示设备从STR待机状态进入开机状态的流程的相关说明。
进一步，在一些应用场景中，显示设备可通过HDMI端子连接外部设备，并被配置为启动HDMI-CEC控制服务，例如，如图3所示，为显示设备上HDMI-CEC控制服务配置界面的示意图，用户通过点击图3所示例的配置界面上的按钮300可以启动或关闭HDMI-CEC控制服务。
在该应用场景中，显示设备接收到待机指令后进入STR待机流程，同时外部设备也进入待机状态。以下结合图4对显示设备响应于待机指令进入待机状态以及外部设备同步进入待机状态的处理流程进行说明。
如图4所示，用户通过按压控制装置上电源键向处于开机状态的显示设备输入电源关闭指令，显示设备接收到该电源关闭指令，调用***底层的按键驱动层进入STR待机，发送关屏广播以使显示器关屏；CEC控制模块接收到关屏广播后发送待机指令给HDMI端子连接的外部设备，使得外部设备也进入待机状态。
进一步，当用户通过按压控制装置上的电源键向处于STR待机状态的显示设备输入待机至开机的电源启动指令时，显示设备响应于该电源启动指令，控制电源电路至少为存储器、控制器和显示器供电，以使显示设备从待机状态进入开机状态。在显示设备从待机状态进入开机状态后，显示设备可以调用***预置的HdmiControlService服务中的deviceSelect函数，实现调用***底层的CEC驱动层，从而唤醒通过HDMI端子连接的外部设备。待外部设备唤醒后，显示设备可以切换至外部设备对应的信号源，例如HDMI信号源，并在显示器上显示外部设备提供内容的图形用户界面，例如，如图5所示，为外部设备提供内容的图形用户界面500的示意图。
在该应用场景中，当用户通过按压控制装置上的快捷应用键向处于STR待机状态的显示设备输入快捷应用启动指令时，显示设备响应于该快捷应用启动指令，控制电源电路至少为存储器、控制器和显示器供电，以使显示设备从待机状态进入开机状态，显示设备进入开机状态后，启动快捷应用并显示快捷应用对应的图形用户界面；同时，按照上述处理流程进行HDMI信号源的切换，以在显示器上显示外部设备提供的图形用户界面。这样，显示设备上就会先显示快捷应用对应的图形用户界面，然后再改变为外部设备提供内容的图形用户界面，导致不符合用户期望。
以下结合图6对显示设备被配置为启动HDMI-CEC控制服务时响应于快捷应用启动指令从待机状态进入开机状态的处理流程进行说明。
如图6所示，用户通过按压控制装置上的快捷键向处于STR待机状态的显示设备输入快捷应用启动指令，当显示设备接收到该快捷应用启动指令时，上传数据至驱动层，以进行STR开机；更新开机原因，例如将存放在/sys/kernel/wakeup_reasons/路径下的开机原因配置文件mstar_resume_reason中开机原因字段reson：的值修改为快捷应用启动指令对应的快捷应用的应用名称；发送亮屏广播，使得一键启动Service收到亮屏广播后控制显示器亮屏，并启动快捷应用，此时显示器上显示快捷应用提供的图形用户界面，例如图2所示例的界面。
然而，如图6所示，在上述流程中，更新开机原因之后，还包括以下处理过程：LiveTv中MainActivity主界面调用onResume()方法，使得显示设备切换至HDMI信号源；CEC控制模块唤醒HDMI端子连接的外部设备，并检查显示器当前显示的界面是否为HDMI信号源提供的图形用户界面，若否，则控制显示器显示HDMI信号源提供的图形用户界面。
至此，显示设备进入开机状态并显示HDMI信号源提供的图形用户界面，而非显示快捷应用提供的图形用户界面，与用户期望不符。
基于此，本申请提供一种显示设备处于待机状态时被唤醒的方法，该方法的应用场景为：显示设备被配置为启用HDMI-CEC控制服务，并且，显示设备处于待机状态，例如STR待机状态。图7示例性示出了显示设备处于待机状态时被唤醒的方法的流程图。
结合图7所示方法来说，该方法包括以下步骤：
步骤S71：接收到用户输入的快捷应用启动指令。
示例性的，用户可通过按压控制装置上快捷应用键，例如图1E所示例的遥控器100A上的A、B、C、D任一按键向处于待机状态的显示设备输入快捷应用启动指令。
步骤S72：控制电源管理模块至少为存储器、控制器和显示器供电，以使显示设备从待机状态进入开机状态。
步骤S73：配置显示设备从待机状态进行开机状态的开机原因，以使显示设备根据已配置的开机原因，在显示器上显示快捷应用启动指令对应的目标快捷应用的图形用户界面。
示例性的，开机原因以指示标记来表示，其中，当开机原因的指示标记为第一值，例如1时，表示控制器响应于快捷应用启动指令而使显示设备从待机状态进入开机状态；当开机原因的指示标记为第二值，例如0时，表示控制器响应于电源启动指令而使显示设备从待机状态进入开机状态。
本步骤中，响应于用户输入的快捷应用启动指令，将开机原因的指示标记置为上述第一值，以使显示设备根据已配置的开机原因的指示标记在显示器上显示快捷应用启动指令对应的目标快捷应用的图形用户界面。
由此可见，通过图7所示方法，可以实现在显示设备被配置为启用HDMI-CEC控制服务，并且，显示设备处于待机状态时，用户通过按压控制装置上的快捷应用键向显示设备输入快捷应用启动指令，可以使得显示设备从待机状态进入开机状态并在显示器上显示快捷应用启动指令对应的目标快捷应用的图形用户界面，而不显示外部设备提供的图形用户界面，可以满足用户期望。
下面为了加深理解，结合图8对图7所示例的方法进行进一步说明：
如图8所示，用户通过按压控制装置上的快捷键向处于STR待机状态的显示设备输入快捷应用启动指令，当显示设备接收到该快捷应用启动指令时，上传数据至驱动层，以进行STR开机；更新开机原因并同步将开机原因指示标记置为第一值，例如1；发送亮屏广播，使得一键启动Service收到亮屏广播后控制显示器亮屏并启动快捷应用，此时，显示器上显示快捷应用启动指令对应的目标快捷应用的图形用户界面，例如图2所示例的界面。
进一步，如图8所示，更新开机原因并同步将开机原因指示标记置为第一值之后，还包括以下处理过程：LiveTv中MainActivity主界面调用onResume()方法，以判断开机原因的指示标记是否置为第一值，若是，则控制CEC控制模块不发送开机指令给HDMI端子连接的外部设备，使得外部设备也进入开机状态，也即不执行外部设备对应的信号源的切换步骤；并将开机原因的指示标记从第一值置为第二值。至此，显示器上仍显示快捷应用启动指令对应的目标快捷应用的图形用户界面，满足用户期望。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包括这些改动和变型在内。
