具体实施方式
为使本申请的原理、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请主要针对显示系统中具有双控制器(也可以称为双硬件系统)、双显示器结构的显示设备，即具有第一控制器、第二控制器、第一显示器和第二显示器的显示设备。需要说明的是，本申请提供的显示设备不仅具有双控制器和双显示器，还可以具有其他结构，后续实施例会对此进行详细说明。本申请用于实现焦点在显示设备中的第一显示器和第二显示器之间进行切换。下面首先对本申请提供的显示设备的结构、功能和实现方式等方面进行详细说明。
在对显示设备的结构、功能和实现方式等方面进行详细说明之前，首先结合附图对本申请所涉及的概念进行说明。在此需要指出的是，以下对各个概念的说明，仅为了使本申请的内容更加容易理解，并不表示对本申请保护范围的限定。
本申请各实施例中使用的术语“模块”，可以是指任何已知或后来开发的硬件、软件、固件、人工智能、模糊逻辑或硬件或/和软件代码的组合，能够执行与该模块相关的功能。
本申请各实施例中使用的术语“遥控器”，是指用于控制显示设备的一个组件，该组件通常可在较短的距离范围内无线控制显示设备。遥控器一般可以使用红外线、射频(RF)信号和/或蓝牙连接电子设备，也可以包括WiFi、无线USB、蓝牙、动作传感器等功能模块。例如：手持式触摸遥控器，是以触摸屏中用户界面取代一般遥控装置中的大部分物理按键。
本申请各实施例中使用的术语“手势”，是指用户通过一种手型的变化或手部运动等动作，用于表达预期想法、动作、目的/或结果的用户行为。
本申请各实施例中使用的术语“硬件系统”，可以是指由集成电路(Integrated Circuit，IC)、印刷电路板(Printed circuit board，PCB)等机械、光、电、磁器件构成的具有计算、控制、存储、输入和输出功能的实体部件。在本申请各个实施例中，硬件系统通常也会被称为主板(motherboard)或芯片。
图1为本申请实施例提供的一种显示设备与控制设备之间操作场景的示意图。如图1所示，显示系统包括显示设备200和控制设备100，用户可通过控制设备100来操作显示设备200。
其中，控制设备100可以是遥控器100A，其可与显示设备200之间通过红外协议通信、蓝牙协议通信、紫蜂(ZigBee)协议通信或其他短距离通信方式进行通信，用于通过无线或有线方式来控制显示设备200。用户可以通过遥控器100A上按键、语音输入、控制面板输入等输入用户指令，来控制显示设备200。如：用户可以通过遥控器100A上音量加减键、频道控制键、上/下/左/右的移动按键、语音输入按键、菜单键、开关机按键等输入相应控制指令，来实现控制显示设备200的功能。
控制设备100也可以是智能设备，如移动终端100B、平板电脑、计算机、笔记本电脑等，其可以通过本地网(LAN，Local Area Network)、广域网(WAN，Wide Area Network)、无线局域网(WLAN，Wireless Local Area Network)或其他网络与显示设备200之间通信，并通过与显示设备200相应的应用程序实现对显示设备200的控制。例如，使用在智能设备上运行的应用程序控制显示设备200。该应用程序可以在与智能设备关联的屏幕上通过直观的用户界面(UI，User Interface)为用户提供各种控制。
示例的，移动终端100B与显示设备200均可安装软件应用，从而可通过网络通信协议实现二者之间的连接通信，进而实现一对一的控制操作和数据通信的目的。如：可以使移动终端100B与显示设备200建立控制指令协议，将遥控控制键盘同步到移动终端100B上，通过控制移动终端100B上用户界面，实现控制显示设备200的功能；也可以将移动终端100B上显示的音视频内容传输到显示设备200上，实现同步显示功能(也称投屏功能)。
如图1所示，显示设备200还可与服务器300(显示系统还可以包括该服务器300)通过多种通信方式进行数据通信。在本申请各个实施例中，可允许显示设备200通过局域网、无线局域网或其他网络与服务器300进行有线通信连接或无线通信连接。服务器300可以向显示设备200提供各种内容和互动。
示例的，显示设备200通过发送和接收信息，以及电子节目指南(EPG，Electronic Program Guide)互动，接收软件程序更新，或访问远程储存的数字媒体库。服务器300可以是一组，也可以是多组，可以是一类或多类服务器。通过服务器300提供视频点播和广告服务等其他网络服务内容。
显示设备200包括第一显示器201与第二显示器202，其中，第一显示器201与第二显示器202之间相互独立，第一显示器201与第二显示器202之间采用双硬件控制系统。
其中，第一显示器201和第二显示器202可以用于显示不同的显示画面。如，第一显示器201可以用于传统电视节目的画面显示，第二显示器202用于通知类消息、语音助手等辅助信息的画面显示。第二显示器202用于显示的信息比如可以是：定期更新的信息(如时间、天气、网络状态信息)，系统通知提醒类信息(如新设备接入提示信息)，一键搜图功能对应的新弹出的窗口信息，观看流媒体视频的弹幕窗口信息，社交电视功能下外部来电的通知信息，社交电视功能下扩展显示的视频图像信息等。
示例地，当新的设备(如新媒体通用串行总线(Universal Serial Bus，USB)设备、高清多媒体接口(High Definition Multimedia Interface，HDMI)设备)接入显示设备时，可以在第二显示器上显示弹出的提示窗口。
又示例地，在用户观看显示设备在第一显示器中播放的视频的过程中，如果用户对视频中的某个人物、服饰感兴趣，则用户可以使用控制设备的一键图搜功能，触发显示设备在第二显示器上显示搜索的信号弹出对应的窗口。
再示例地，用户在观看显示设备在第一显示器中播放的视频的过程中，有视频通话接入，则显示设备可以在第二显示器中显示视频来电的通知提醒，同时可以将接入的对方的视频信息由第二显示器显示。并且，显示设备还可以与视频接入方共享第一显示器中播放的视频。
再示例地，当用户在操控控制设备进行语音输入时，显示设备可以在第二显示器上显示语音输入对应的文字，并且，还可以在第一显示器上显示视频，此时，由于第二显示器上显示的文字并未遮挡第一显示器上显示的视频，因此提升了用户体验。
再示例地，显示设备显示的开机动画(或者其他动画)通常是在一个显示器中显示。对于本申请实施例提供的显示设备，开机动画(或者其他动画)可以在显示设备的第一显示器和第二显示器之间移动，也即，这两个显示器作为一个整体的显示器进行开机动画(或者其他动画)的显示。这样一来，可以提升整个显示设备中显示开机动画的区域的面积，提升用户体验。
可选地，第一显示器201显示的内容与第二显示器202显示的内容之间可以相互独立，互不影响。例如，在第一显示器201播放电视节目时，第二显示器202可以显示与电视节目无关的时间、天气、气温、提醒消息等信息。
可选地，第一显示器201显示的内容与第二显示器202显示的内容之间也可以存在关联关系。例如，在第一显示器201播放视频聊天的主画面时，第二显示器202可以显示当前接入视频聊天的用户的头像、聊天时长等信息。
可选地，第二显示器202显示的部分或全部内容可以调整至第一显示器201显示。例如，可以将第一显示器201显示的时间、天气、气温、提醒消息等信息调整到第一显示器201显示，而用第二显示器202显示其它的信息。
另外，第一显示器201在显示传统电视节目画面的同时，还显示多方交互画面，且多方交互画面不会遮挡传统电视节目画面。其中，本申请对传统电视节目画面和多方交互画面的显示方式不做限定。例如，本申请可以根据传统电视节目画面和多方交互画面的优先级，设置传统电视节目画面和多方交互画面的位置和大小。以传统电视节目画面的优先级高于多方交互画面的优先级为例，传统电视节目画面的面积大于多方交互画面的面积，且多方交互画面可以位于传统电视节目画面的一侧，也可以悬浮设置在多方交互画面的一角。
当然，也可以是第一显示器201显示传统电视节目画面，并由第二显示器202显示多方交互画面。
显示设备200，一方面讲，可以是液晶显示器、OLED(Organic Light Emitting Diode)显示器、投影显示设备；另一方面讲，显示设备被可以是智能电视或显示器和机顶盒组成的显示系统。具体显示设备类型，尺寸大小和分辨率等不作限定，本领技术人员可以理解的是，显示设备200可以根据需要做性能和配置上的一些改变。
显示设备200除了提供广播接收电视功能之外，还可以附加提供计算机支持功能的智能网络电视功能。示例的包括，网络电视、智能电视、互联网协议电视(IPTV)等功能。在一些实施例中，显示设备可以不具备广播接收电视功能。
显示系统还可以包括与显示设备连接的摄像头，如图1所示，该摄像头可以设置在显示设备200上(当然也可以与显示设备200相互独立)，用于将摄像头拍摄到的画面呈现在本显示设备或其他显示设备的显示界面上，以实现用户之间的交互聊天。具体的，摄像头拍摄到的画面可在显示设备上全屏显示、半屏显示、或者显示任意可选区域。
作为一种可选的连接方式，摄像头通过连接板与显示设备的后壳连接，固定安装在显示设备的后壳的上侧中部，作为可安装的方式，可以固定安装在显示设备的后壳的任意位置，能保证其图像采集区域不被后壳遮挡即可，例如，图像采集区域与显示设备的显示朝向相同。
作为另一种可选的连接方式，摄像头通过连接板或者其他可想到的连接器可升降的与显示设备后壳连接。连接器上可以安装有升降马达，当用户要使用摄像头或者有应用程序要使用摄像头时，再升出显示设备之上，当不需要使用摄像头时，其可内嵌到后壳之后，以达到保护摄像头免受损坏和保护用户的隐私安全。
作为一种实施例，本申请所采用的摄像头可以为1600万像素，以达到超高清显示目的。在实际使用中，也可采用比1600万像素更高或更低的摄像头。
当显示设备上安装有摄像头以后，显示设备不同应用场景所显示的内容可得到多种不同方式的融合，从而达到传统显示设备无法实现的功能。
示例性的，用户可以在边观看视频节目的同时，与至少一位其他用户进行视频聊天。视频节目呈现在第一显示器，视频聊天显示在第二显示器上。形象的，可以称该功能为“边看边聊”。
可选的，在“边看边聊”的场景中，在观看直播视频或网络视频的同时，跨终端的进行至少一路的视频聊天。
另一示例中，用户可以在边进入教育应用学习的同时，与至少一位其他用户进行视频聊天。例如，学生在学习教育应用程序中内容的同时，可实现与老师的远程互动。形象的，可以称该功能为“边学边聊”。
另一示例中，用户在玩纸牌游戏时，与进入游戏的玩家进行视频聊天。例如，玩家在进入游戏应用参与游戏时，可实现与其他玩家的远程互动。形象的，可以称该功能为“边玩边聊”。
可选的，游戏场景与视频画面进行融合，将视频画面中人像进行抠图，显示在游戏画面中，提升用户体验。

需要说明的是：视图显示区可呈现视频聊天项目内容，或者呈现应用层项目内容(如，网页视频、云点播(Video on Demand，VOD)展示、应用程序画面等)。
基于上述内容，本申请实施例提供了一种显示设备，如图7所示，该显示设备70不仅包括：第一显示器701、第一控制器702、第二显示器703以及第二控制器704，该显示设备还可以包括焦点判断器705。其中，焦点判断器705通信连接第一控制器702、第二控制器704和显示设备70的控制设备80(如上述遥控器或智能终端)；第一控制器702通信连接第一显示器701，第二控制器704通信连接第二显示器703。
焦点判断器705与第一控制器702和第二控制器704均可以相互独立，焦点判断器705也可以集成在第一控制器702上，或者焦点判断器705集成在第二控制器704上，本申请实施例对此不作限定。
焦点判断器705可以用于：检测切换条件是否满足，并且在切换条件满足时，向第一控制器702发送用于指示停止显示焦点的焦点停止指令，以及向第二控制器704发送用于指示显示焦点的焦点显示指令。其中，切换条件包括：第一控制器702控制第一显示器701显示焦点，且第二控制器704控制第二显示器703未显示焦点，且焦点判断器705接收到控制设备80发送的焦点切换指令，焦点切换指令用于指示焦点由第一显示器701切换至第二显示器703。
需要说明的是，第一控制器702可以是显示设备中的任一控制器，根据上述切换条件可知，在显示设备中的任一控制器控制其通信连接的显示器显示焦点，且另一控制器并未控制另一显示器显示焦点的情况下，若用户操控控制设备80向焦点判断器705发送了焦点切换指令，则焦点判断器705可以确定当前用户需要控制焦点从当前显示的显示器切换至另一显示器，进而向第一控制器702发送焦点停止指令，以及向第二控制器704发送焦点显示指令，从而触发焦点在这两个控制器连接的显示器之间切换。
在焦点判断器705向第一控制器702发送焦点停止指令后，第一控制器702可以用于根据焦点停止指令，控制第一显示器701停止显示焦点；在焦点判断器705向第二控制器 704发送焦点显示指令后，第二控制器704可以用于根据焦点显示指令，控制第二显示器703显示焦点。
可以看出，在焦点判断器705向第一控制器702发送焦点停止指令，以及向第二控制器704发送焦点显示指令之后，第一控制器702可以执行焦点停止指令，第二控制器704可以执行焦点显示指令，从而使得焦点从第一显示器701切换至第二显示器703。
综上所述，本申请实施例提供的显示设备中，每个显示器都具有显示焦点的功能，并且，焦点判断器能够控制第一控制器和第二控制器，实现焦点在第一显示器和第二显示器之间切换。因此，焦点可以先在一个显示器上显示，以使用户可以根据焦点对该一个显示器所显示的项目进行选择，之后焦点再在另一个显示器上显示，以使用户还可以根据焦点对该另一个显示器所显示的项目进行选择。因此，丰富了显示设备的功能。
需要说明的是，在显示设备启动后，第一显示器701和第二显示器703中默认有一个显示器在默认位置显示有焦点。之后，用户可以通过操控显示设备的控制设备，通过本申请实施例提供的焦点切换方法，控制焦点在这两个显示器之间来回切换。
本申请实施例中，焦点判断器705可以通过多种方式确定是否接收到控制设备80发送的焦点切换指令。
比如，控制设备80上具有用于触发控制设备80生成焦点切换指令的按键，用户可以通过按压该按键以触发控制设备80生成焦点切换指令，并向焦点判断器705发送该焦点切换指令。
又比如，焦点判断器705可以通过判断触发条件是否满足，来确定控制设备80向焦点判断器705发送的针对焦点的操作指令是否为焦点切换指令。示例地，当该触发条件满足时，焦点判断器705可以将当前接收到的操作指令确定为焦点切换指令。当该触发条件不满足时，焦点判断器705并不将当前接收到的操作指令确定为焦点切换指令，并将该操作指令发送至当前显示焦点的显示器所连接的控制器，以便于该控制器执行该操作指令。其中，上述触发条件包括：第一显示器701(当前显示有焦点的显示器)显示的焦点位于第一显示器701显示的多个项目中靠近第二显示器703的边界项目上，且操作指令用于指示焦点向靠近第二显示器703的方向移动。
示例地，图8为本申请实施例提供的一种显示设备显示焦点的示意图，图8中以第一显示器701和第二显示器703从左到右依次排布，且第一显示器701的显示区域大于第二显示器703的显示区域为例。如图8所示，第一显示器701显示有4行4列项目，且焦点位于第一显示器701显示的第1行第4列项目上，第二显示器703位于第一显示器701的右边，第二显示器703显示有4行2列项目，且第二显示器703并未显示焦点。用户通过操控控制设备向焦点判断器发送控制焦点右移的操作指令，则焦点判断器便可以确定当前接收到的该操作指令为焦点切换指令。此时，焦点判断器便可以向第一控制器发送焦点停止指令，以及向第二控制器发送焦点显示指令，从而如图9所示，第一控制器控制第一显示器701停止显示焦点，且第二控制器控制第二显示器703显示焦点，比如第二控制器控制第二显示器703显示4行2列项目，并将焦点显示在4行2列项目中第1行第1列的项目上。
需要说明的是，焦点在从一个显示器切换至另一个显示器时，该另一个显示器可以在默认的位置显示该焦点。图9中以第1行第1列的项目所在的位置为该默认的位置为例，可选地，该默认的位置也可以是其他位置，本申请实施例对此不作限定。根据图8和图9中焦点的切换方式可知，焦点能够在第一显示器和第二显示器之间进行平滑的切换，以使用户能够有第一显示器和第二显示器能够组成一个整体显示器的感觉，提升用户体验。
需要说明的是，在显示设备中的任一显示器显示焦点的过程中，用户均可以操控控制设备80向焦点判断器705发送针对焦点的操作指令。之后，焦点判断器705便可以首先确定当前显示焦点的显示器，之后再将该操作指令发送至当前显示焦点的显示器通信连接的控制器，以便于该控制器执行该操作指令，控制第一显示器和第二显示器中的至少一个显示器显示针对焦点的操作界面。
可选地，针对焦点的操作指令包括：控制焦点移动的指令，或者，指示在焦点所在显示器显示另一显示器正在显示的图像的指令，或者，指示在焦点所在的显示器显示该项目的下一级项目的指令等。
示例地，图10为本申请实施例提供的一种第一显示器显示焦点的示意图，如图10所示，第一显示器701在显示焦点时，可以显示包含焦点的第一焦点界面。该第一焦点界面可以包含多个项目，该焦点可以位于该多个项目中的任一项目上。比如图10中该多个项目排成4行4列，该焦点可以位于第1行第1列的项目上。用户在通过操控控制设备向焦点判断器发送控制焦点右移的操作指令后，焦点判断器便可以将该操作指令发送至第一控制器，以使第一控制器控制第一显示器701显示如图11所示的第三焦点界面，该第三焦点界面也包含焦点和上述多个项目，但该焦点相对图10所示的焦点进行了右移，图11中的焦点位于4行4列项目中第1行第2列的项目上。第二显示器显示焦点的状态可以参考第一显示器显示焦点的状态，本申请实施例在此不做赘述。
又示例地，如图12所示，假设第一显示器701显示视频1，且第二显示器703显示焦点，若上述操作指令用于指示第二显示器703也显示第一显示器701显示的视频1，则第二控制器可以在第一控制器上查询视频1的信息，并根据查询到的视频1的信息控制第二显示器703也显示视频1(如图13所示)。可选地，在第二显示器703显示视频1的情况下，第一显示器701可以显示视频1，也可以停止显示视频1，本申请实施例对此不作限定，图13中以第一显示器701继续显示视频1为例。
再示例地，在第一显示器显示如图8所示的第一焦点界面时，若用户通过操控控制设备向焦点判断器发送指示在第一显示器显示焦点所在项目的下一级项目的操作指令，则焦点判断器可以将该操作指令发送至第一控制器，以使第一控制器控制第一显示器显示如图14所示的第四焦点界面，该第四焦点界面也包含焦点和上述多个项目，该第四焦点界面还包括图8中焦点所在项目的多个下一级项目，并且图14中的焦点位于该多个下一级项目中的第一个项目上。第二显示器显示焦点的状态可以参考第一显示器显示焦点的状态，本申请实施例在此不做赘述。
可选地，第一显示器701在未显示焦点时，显示的界面可以称为第一非焦点界面；第二显示器703在未显示焦点时，显示的界面可以称为第二非焦点界面。第一显示器701 在显示焦点时，显示的界面可以称为第一焦点界面；第二显示器703在显示焦点时，显示的界面可以称为第二焦点界面。
第一控制器702在控制第一显示器701停止显示焦点之前，还可以用于获取用于第一显示器701显示且不包含焦点的第一非焦点界面的信息。在接收到焦点停止指令之后，第一控制器702可以根据焦点停止指令，以及第一非焦点界面的信息，控制第一显示器701显示第一非焦点界面。第二控制器704在控制第二显示器703显示焦点之前，还可以用于获取用于第二显示器703显示且包含焦点的第二焦点界面的信息。在接收到焦点显示指令之后，第二控制器704可以根据焦点显示指令，以及第二焦点界面的信息，控制第二显示器703显示第二焦点界面。
本申请实施例中，各个控制器可以通过多种方式获取到需要显示的界面的信息。本申请实施例以以下两种方式为例，对控制器获取需要显示的界面的信息进行举例说明。
在第一种方式中，如图15所示，显示设备还包括：第一控制器702通信连接的第一多媒体器706，以及第二控制器704通信连接的第二多媒体器707。第一控制器702可以从第一多媒体器706上获取第一显示器701需要显示的界面的信息。第二控制器704可以从第二多媒体器707上获取第二显示器703需要显示的界面的信息。比如，第一控制器702用于在接收到焦点停止指令时，从第一多媒体器706上获取第一非焦点界面的信息；第二控制器704用于在接收到焦点显示指令时，从第二多媒体器707上获取第二焦点界面的信息。
在第二种方式中，如图16所示，显示设备还包括：焦点判断器705通信连接的第三多媒体器708。焦点判断器705用于：在接收到焦点切换指令时，从第三多媒体器708上获取第一非焦点界面的信息以及第二焦点界面的信息，并将第一非焦点界面的信息携带在焦点停止指令中，以及将第二焦点界面的信息携带在焦点显示指令中；第一控制器702用于从焦点停止指令中获取第一非焦点界面的信息；第二控制器704用于从焦点显示指令中获取第二焦点界面的信息。可见，第一显示器701和第二显示器703需要显示的界面的信息均由焦点判断器705从第三多媒体器708上获取，并将这些信息分别携带在发往控制器的指令中。
综上所述，本申请实施例提供的显示设备中，每个显示器都具有显示焦点的功能，并且，焦点判断器能够控制第一控制器和第二控制器，实现焦点在第一显示器和第二显示器之间切换。因此，焦点可以先在一个显示器上显示，以使用户可以根据焦点对该一个显示器所显示的项目进行选择，之后焦点再在另一个显示器上显示，以使用户还可以根据焦点对该另一个显示器所显示的项目进行选择。因此，丰富了显示设备的功能。
图17为本申请实施例提供的一种焦点切换方法的流程图，该方法用于本申请实施例提供的任一种显示设备，如图17所示，该方法可以包括：
步骤1701、在切换条件满足时，焦点判断器向第一控制器发送用于指示停止显示焦点的焦点停止指令，以及向第二控制器发送用于指示显示焦点的焦点显示指令。
其中，切换条件包括：第一控制器控制第一显示器显示焦点，且第二控制器控制第二 显示器未显示焦点，且焦点判断器接收到控制设备发送的焦点切换指令，焦点切换指令用于指示焦点由第一显示器切换至第二显示器。
步骤1702、第一控制器根据焦点停止指令，控制第一显示器停止显示焦点。
步骤1703、第二控制器根据焦点显示指令，控制第二显示器显示焦点。
综上所述，本申请实施例提供的焦点切换方法中，焦点判断器能够控制第一控制器和第二控制器，实现焦点在第一显示器和第二显示器之间切换。因此，焦点可以先在一个显示器上显示，以使用户可以根据焦点对该一个显示器所显示的项目进行选择，之后焦点再在另一个显示器上显示，以使用户还可以根据焦点对该另一个显示器所显示的项目进行选择。因此，丰富了显示设备的功能。
图18为本申请实施例提供的另一种焦点切换方法的流程图，该方法用于本申请实施例提供的任一种显示设备，如图18所示，该方法可以包括：
步骤1801、在第一控制器控制第一显示器显示焦点，且第二控制器控制第二显示器未显示焦点时，焦点判断器接收控制设备发送的针对焦点的操作指令。
在显示设备中的任一显示器显示焦点的过程中，用户均可以操控控制设备向焦点判断器发送针对焦点的操作指令。之后，焦点判断器便可以首先确定当前显示焦点的显示器，之后再将该操作指令发送至当前显示焦点的显示器通信连接的控制器，以便于该控制器执行该操作指令，控制第一显示器和第二显示器中的至少一个显示器显示针对焦点的操作界面。
可选地，针对焦点的操作指令包括：控制焦点移动的指令，或者，指示在焦点所在显示器显示另一显示器正在显示的图像的指令，或者，指示在焦点所在的显示器显示该项目的下一级项目的指令等。
示例地，如图10所示，第一显示器在显示焦点时，可以显示包含焦点的第一焦点界面。该第一焦点界面可以包含多个项目，该焦点可以位于该多个项目中的任一项目上。比如图10中该多个项目排成4行4列，该焦点可以位于第1行第1列的项目上。用户在通过操控控制设备向焦点判断器发送控制焦点右移的操作指令后，焦点判断器便可以将该操作指令发送至第一控制器，该操作指令用于使第一控制器控制第一显示器显示如图11所示的第三焦点界面，该第三焦点界面也包含焦点和上述多个项目，但该焦点相对图10所示的焦点进行了右移，图11中的焦点位于4行4列项目中第1行第2列的项目上。
又示例地，如图12所示，假设第一显示器701显示视频1，且第二显示器703显示焦点，上述操作指令可以用于指示第二显示器703也显示第一显示器701显示的视频1，使第二控制器可以在第一控制器上查询视频1的信息，并根据查询到的视频1的信息控制第二显示器703也显示视频1(如图13所示)。
再示例地，在第一显示器显示如图8所示的第一焦点界面时，若用户通过操控控制设备向焦点判断器发送指示在第一显示器显示焦点所在项目的下一级项目的操作指令，则焦点判断器可以将该操作指令发送至第一控制器。该操作指令可以使第一控制器控制第一显示器显示如图14所示的第四焦点界面，该第四焦点界面也包含焦点和上述多个项目，该 第四焦点界面还包括图10中焦点所在项目的多个下一级项目，并且图14中的焦点位于该多个下一级项目中的第一个项目上。
步骤1802、在触发条件满足时，焦点判断器确定接收到的操作指令为焦点切换指令。
其中，触发条件包括：第一显示器显示的焦点位于多个项目中靠近第二显示器的边界项目上，且操作指令用于指示焦点向靠近第二显示器的方向移动。
示例地，如图8所示，第一显示器701显示有4行4列项目，且焦点位于第一显示器701显示的第1行第4列项目上，第二显示器703位于第一显示器701的右边，第二显示器703显示有4行2列项目，且第二显示器703并未显示焦点。用户通过操控控制设备向焦点判断器发送控制焦点右移的操作指令，则焦点判断器便可以确定当前接收到的该操作指令为焦点切换指令。
本申请实施例中，焦点判断器可以通过判断触发条件是否满足，来确定控制设备向焦点判断器发送的针对焦点的操作指令是否为焦点切换指令。可选地，焦点判断器还可以通过其他方式确定是否接收到控制设备发送的焦点切换指令。比如，控制设备上具有用于触发控制设备生成焦点切换指令的按键，用户可以通过按压该按键以触发控制设备生成焦点切换指令，并向焦点判断器发送该焦点切换指令。
步骤1803、在切换条件满足时，焦点判断器向第一控制器发送用于指示停止显示焦点的焦点停止指令，以及向第二控制器发送用于指示显示焦点的焦点显示指令。
切换条件包括：第一控制器控制第一显示器显示焦点，且第二控制器控制第二显示器未显示焦点，且焦点判断器接收到控制设备发送的焦点切换指令，焦点切换指令用于指示焦点由第一显示器切换至第二显示器。
需要说明的是，第一控制器可以是显示设备中的任一控制器，根据上述切换条件可知，在显示设备中的任一控制器控制其通信连接的显示器显示焦点，且另一控制器并未控制另一显示器显示焦点的情况下，若用户操控控制设备向焦点判断器发送了焦点切换指令，则焦点判断器可以确定当前用户需要控制焦点从当前显示的显示器切换至另一显示器，进而向第一控制器发送焦点停止指令，以及向第二控制器发送焦点显示指令，从而触发焦点在这两个控制器连接的显示器之间切换。
步骤1804、第一控制器获取用于第一显示器显示且不包含焦点的第一非焦点界面的信息。
需要说明的是，在步骤1804中，第一控制器可以通过多种方式获取到需要显示的界面的信息。本申请实施例以以下两种方式为例，对第一控制器获取需要显示的界面的信息进行举例说明。
在第一种方式中，如图15所示，显示设备还包括：第一控制器702通信连接的第一多媒体器706。第一控制器702可以从第一多媒体器706上获取第一显示器701需要显示的界面的信息。比如，在步骤1804中，第一控制器702在接收到焦点停止指令时，从第一多媒体器706上获取第一非焦点界面的信息。
在第二种方式中，如图16所示，显示设备还包括：焦点判断器705通信连接的第三多媒体器708。在步骤1803之前，也即焦点判断器705在发送焦点停止指令和焦点显示 指令之前，可以从第三多媒体器708上获取第一非焦点界面的信息，并将第一非焦点界面的信息携带在焦点停止指令中。在步骤1804中，第一控制器可以从焦点停止指令中获取第一非焦点界面的信息。可见，第一显示器需要显示的界面的信息均由焦点判断器从第三多媒体器上获取，并将这些信息携带在发往控制器的指令中。
步骤1805、第一控制器根据焦点停止指令，控制第一显示器停止显示焦点。
步骤1806、第一控制器根据焦点停止指令，以及第一非焦点界面的信息，控制第一显示器显示第一非焦点界面。
如图9所示，第一控制器在接收到焦点停止指令后，可以控制第一显示器701停止显示焦点，并显示第一非焦点界面，该第一非焦点界面可以相比图8所示的第一焦点界面缺少了焦点。比如第一非焦点界面仅包括图8所示的多个项目。
步骤1807、第二控制器获取用于第二显示器显示且包含焦点的第二焦点界面的信息。
需要说明的是，在步骤1807中，第二控制器可以通过多种方式获取到需要显示的界面的信息。本申请实施例以以下两种方式为例，对第二控制器获取需要显示的界面的信息进行举例说明。
在第一种方式中，如图15所示，显示设备还包括：第二控制器704通信连接的第二多媒体器707。第二控制器704可以从第二多媒体器707上获取第二显示器703需要显示的界面的信息。比如，在步骤1807中，第二控制器704在接收到焦点显示指令时，从第二多媒体器707上获取第二焦点界面的信息。
在第二种方式中，如图16所示，显示设备还包括：焦点判断器705通信连接的第三多媒体器708。在步骤1803之前，也即焦点判断器705在发送焦点停止指令和焦点显示指令之前，可以从第三多媒体器708上获取第二焦点界面的信息，并将第二焦点界面的信息携带在焦点显示指令中。在步骤1807中，第二控制器用于从焦点显示指令中获取第二焦点界面的信息。可见，第二显示器需要显示的界面的信息均由焦点判断器从第三多媒体器上获取，并将这些信息携带在发往控制器的指令中。
步骤1808、第二控制器根据焦点显示指令，以及第二焦点界面的信息，控制第二显示器显示第二焦点界面。
如图9所示，第二控制器在控制第二显示器703显示焦点时，可以控制第二显示器显示如图9所示的包含焦点的第二焦点界面。该第二焦点界面可以包括4行2列项目和焦点，且焦点位于4行2列项目中第1行第1列的项目上。
可以看出，在焦点判断器向第一控制器发送焦点停止指令，以及向第二控制器发送焦点显示指令之后，第一控制器可以执行焦点停止指令，第二控制器可以执行焦点显示指令，从而使得焦点从第一显示器切换至第二显示器。
需要说明的是，焦点在从一个显示器切换至另一个显示器时，该另一个显示器可以在默认的位置显示该焦点。图9中以第1行第1列的项目所在的位置为该默认的位置为例，可选地，该默认的位置也可以是其他位置，本申请实施例对此不作限定。根据图8和图9中焦点的切换方式可知，焦点能够在第一显示器和第二显示器之间进行平滑的切换，以使用户能够有第一显示器和第二显示器能够组成一个整体显示器的感觉，提升用户体验。
步骤1809、在触发条件不满足时，焦点判断器将操作指令发送至第一控制器。
在触发条件不满足时，焦点判断器便可以查询当前显示焦点的第一显示器，并将接收到的针对焦点的操作指令发送至第一显示器通信连接的第一控制器。以便于该第一控制器执行该操作指令，控制第一显示器和第二显示器中的至少一个显示器显示针对焦点的操作界面。
步骤1810、第一控制器根据操作指令，控制第一显示器和第二显示器中的至少一个显示器显示针对焦点的操作界面。
可选地，针对焦点的操作指令包括：控制焦点移动的指令，或者，指示在焦点所在显示器显示另一显示器正在显示的图像的指令，或者，指示在焦点所在的显示器显示该项目的下一级项目的指令等。
示例地，如图10所示，第一显示器在显示焦点时，可以显示包含焦点的第一焦点界面。该第一焦点界面可以包含多个项目，该焦点可以位于该多个项目中的任一项目上。比如图10中该多个项目排成4行4列，该焦点可以位于第1行第1列的项目上。用户在通过操控控制设备向焦点判断器发送控制焦点右移的操作指令后，焦点判断器便可以将该操作指令发送至第一控制器，以使第一控制器控制第一显示器显示如图11所示的第三焦点界面，该第三焦点界面也包含焦点和上述多个项目，但该焦点相对图10所示的焦点进行了右移，图11中的焦点位于4行4列项目中第1行第2列的项目上。第二显示器显示焦点的状态可以参考第一显示器显示焦点的状态，本申请实施例在此不做赘述。
又示例地，如图12所示，假设第一显示器701显示视频1，且第二显示器703显示焦点，若上述操作指令用于指示第二显示器703也显示第一显示器701显示的视频1，则第二控制器可以在第一控制器上查询视频1的信息，并根据查询到的视频1的信息控制第二显示器703也显示视频1(如图13所示)。
再示例地，在第一显示器显示如图8所示的第一焦点界面时，若用户通过操控控制设备向焦点判断器发送指示在第一显示器显示焦点所在项目的下一级项目的操作指令，则焦点判断器可以将该操作指令发送至第一控制器，以使第一控制器控制第一显示器显示如图14所示的第四焦点界面，该第四焦点界面也包含焦点和上述多个项目，该第四焦点界面还包括图10中焦点所在项目的多个下一级项目，并且图14中的焦点位于该多个下一级项目中的第一个项目上。第二显示器显示焦点的状态可以参考第一显示器显示焦点的状态，本申请实施例在此不做赘述。
综上所述，本申请实施例提供的焦点切换方法中，焦点判断器能够控制第一控制器和第二控制器，实现焦点在第一显示器和第二显示器之间切换。因此，焦点可以先在一个显示器上显示，以使用户可以根据焦点对该一个显示器所显示的项目进行选择，之后焦点再在另一个显示器上显示，以使用户还可以根据焦点对该另一个显示器所显示的项目进行选择。因此，丰富了显示设备的功能。
