上述说明仅是本申请技术方案的概述,为了能够更清楚了解本申请的技术手段,而可依照说明书的内容予以实施,并且为了让本申请的上述和其它目的、特征和优点能够更明显易懂,以下特举本申请的具体实施方式。
附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍,显而易见地,下面描述中的附图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1示出了本申请实施例的一种显示控制方法的流程图;
图2示出了本申请实施例的第一显示装置和第二显示装置的示意图;
图3示出了本申请实施例的另一种显示控制方法的流程图。
具体实施例
为使本申请的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本申请作进一步详细的说明。
目前,一个显示装置在同一时刻仅能显示一种内容,例如,显示装置应用在教育中,同一时刻只能显示白板书写画面或者电子课件画面,显示装置应用在会议中时,同一时刻也只能显示白板书写画面或者视频画面,若同时需要显示两种不同的内容时,则需要两个显示装置来实现,但是,这两个显示装置都是独自运行和操作的,用户需要分别操作两个显示装置,才可实现两个显示装置的控制。
参照图1,示出了本申请实施例的一种显示控制方法的流程图,应用于显示控制系统中,具体可以包括如下步骤:
步骤101,根据所述第一显示装置和所述第二显示装置运行的操作系统,和/或,所述第一显示装置和所述第二显示装置接收到的触控信息,确定所述第一显示装置和所述第二显示装置的主副关系。
在本申请实施例中,如图2所示,显示控制系统包括第一显示装置21和第二显示装置22,第一显示装置21与第二显示装置22连接,且第一显示装置21和第二显示装置22分别具有操作系统,第一显示装置21和第二显示装置22的操作系统可以是分别独立的操作系统。
其中,第一显示装置21可运行的操作系统为第一操作系统或第二操作系统,第二显示装置22可运行的操作系统为第二操作系统。第一操作系统为Windows操作系统,第二操作系统为Android操作系统。
具体的,在第一显示装置21中设置有OPS(Open Pluggable Specification,开放式可插拔规范)模块,OPS模块实际上是一个可插拔的X86架构的电脑模块,配置有处理器、内存、硬盘、多种输入输出接口以及Windows操作界面。
通常,显示装置的操作系统为Android操作系统,在第一显示装置21中设置OPS模块,使得第一显示装置21既可以支持Android操作系统又可以支持Windows操作系统,而第二显示装置22中未设置有OPS模块,第二 显示装置22仅可以支持Android操作系统。当然,可以理解的是,第一操作系统不局限于Windows操作系统,例如,还可以支持Mac操作系统或Linux操作系统等。
在实际应用中,第一显示装置21与第二显示装置22通过连接线23连接,连接线23可以为HDMI(High Definition Multimedia Interface,高清多媒体接口)线,即第一显示装置21与第二显示装置22通过HDMI线连接。
当然,第一显示装置21与第二显示装置22还可以无线连接,即在第一显示装置21和第二显示装置22内均设置WIFI(Wireless-Fidelity,无线网)模块,通过WIFI模块实现第一显示装置21与第二显示装置22的连接。
此外,第一显示装置21和第二显示装置22的尺寸可以相同也可以不同,当第一显示装置21和第二显示装置22的尺寸不同时,通常在大尺寸的显示装置中设置OPS模块,即第一显示装置21的尺寸会大于第二显示装置22的尺寸,例如,第一显示装置21的尺寸为75英寸,第二显示装置22的尺寸为32英寸。
在将第一显示装置21和第二显示装置22通过连接线23连接之后,将第一显示装置21和第二显示装置22开机,开机后可确定第一显示装置21和第二显示装置22当前运行的操作系统,即确定第一显示装置21当前运行的操作系统是第一操作系统还是第二操作系统,而第二显示装置22当前运行的操作系统默认为第二操作系统。
此外,还可确定第一显示装置21和第二显示装置22接收到的触控信息,第一显示装置21接收到的是第一触控信息,第二显示装置22接收到的是第二触控信息,第一触控信息包括第一显示装置21在开机后首次接收到第一触控操作的第一触控时间,第二触控信息包括第二显示装置22在开机后首次接收到第二触控操作的第二触控时间。
根据第一显示装置21和第二显示装置22运行的操作系统,和/或,第一显示装置21和第二显示装置22接收到的触控信息,确定第一显示装置21和第二显示装置22的主副关系。
第一种方式,是根据第一显示装置21和第二显示装置22运行的操作系统和第一显示装置21和第二显示装置22接收到的触控信息,确定第一显示 装置21和第二显示装置22的主副关系;第二种方式,是仅根据第一显示装置21和第二显示装置22运行的操作系统,确定第一显示装置21和第二显示装置22的主副关系;第三种方式,是仅根据第一显示装置21和第二显示装置22接收到的触控信息,确定第一显示装置21和第二显示装置22的主副关系。
步骤102,基于所述主副关系,主显示装置发送目标信息至副显示装置,以控制所述副显示装置。
在本申请实施例中,在确定了第一显示装置21和第二显示装置22的主副关系之后,基于该主副关系,主显示装置发送目标信息至副显示装置,以控制副显示装置。具体的,主显示装置可控制副显示装置的显示内容、显示模式,以及控制副显示装置打开或关闭目标应用程序等。
在本申请实施例中,通过根据第一显示装置和第二显示装置运行的操作系统,和/或,第一显示装置和第二显示装置接收到的触控信息,确定第一显示装置和第二显示装置的主副关系,基于主副关系,主显示装置发送目标信息至副显示装置,以控制副显示装置。当需要两个显示装置显示两种不同的内容时,根据确定的主副关系,主显示装置可以控制副显示装置,因此,用户只需在主显示装置上进行操作,即可实现两个显示装置的控制,提高用户的使用体验。
参照图3,示出了本申请实施例的另一种显示控制方法的流程图,应用于显示控制系统,具体可以包括如下步骤:
步骤301,当所述第一显示装置和所述第二显示装置当前运行的操作系统不同时,将所述第一显示装置确定为主显示装置,并将所述第二显示装置确定为副显示装置。
在本申请实施例中,第一显示装置21可运行的操作系统为第一操作系统或第二操作系统,第二显示装置22可运行的操作系统为第二操作系统。第一操作系统为Windows操作系统,第二操作系统为Android操作系统。
当第一显示装置21和第二显示装置22当前运行的操作系统不同时,也就是说第一显示装置21当前运行的操作系统为第一操作系统,第二显示装置22当前运行的操作系统为第二操作系统,即第一显示装置21当前运行的 操作系统为Windows操作系统,第二显示装置22当前运行的操作系统为Android操作系统,由于Windows操作系统相对于Android操作系统能够支持更多的功能,因此,将第一显示装置21确定为主显示装置,并将第二显示装置22确定为副显示装置。
具体的,在第一显示装置21中设置有OPS模块,则第一显示装置21开机后,在第一显示装置21的桌面上设置有系统设置图标,第一显示装置21默认的操作系统为第二操作系统,若用户需要切换第一显示装置21的操作系统时,可对该系统设置图标进行触控操作,如单击操作或者双击操作等,则接收到对系统设置图标的触控操作,将第一显示装置21当前运行的操作系统从第二操作系统切换为第一操作系统;若用户不需要切换第一显示装置21的操作系统时,在开机后无需对系统设置图标进行触控操作,第一显示装置21当前运行的操作系统保持为第二操作系统。
需要说明的是,在实际应用中,用户在第一显示装置21开机后,对系统设置图标进行触控操作,将第一显示装置21当前运行的操作系统从第二操作系统切换为第一操作系统,若后续用户需要将第一显示装置21运行的操作系统从第一操作系统再切换回第二操作系统时,可再次对系统设置图标进行触控操作,或者,将第一显示装置21关机后再次开机,使得第一显示装置21运行的操作系统变回第二操作系统。
步骤302,当所述第一显示装置和所述第二显示装置当前运行的操作系统相同时,获取所述第一显示装置接收到的第一触控信息和所述第二显示装置接收到的第二触控信息。
在本申请实施例中,当第一显示装置21和第二显示装置22当前运行的操作系统相同时,也就是说第一显示装置21当前运行的操作系统为第二操作系统,第二显示装置22当前运行的操作系统也为第二操作系统,即第一显示装置21当前运行的操作系统为Android操作系统,第二显示装置22当前运行的操作系统也为Android操作系统,获取第一显示装置21接收到的第一触控信息和第二显示装置22接收到的第二触控信息。
步骤303,根据所述第一触控信息和所述第二触控信息,确定所述第一显示装置和所述第二显示装置的主副关系。
在本申请实施例中,根据第一触控信息和第二触控信息,确定第一显示装置21和第二显示装置的主副关系,实际上是判断开机后首个接收到触控操作的显示装置是第一显示装置21还是第二显示装置22,即确定第一显示装置21和第二显示装置22开机后,用户第一个进行触控操作的显示装置是第一显示装置21还是第二显示装置22。
若第一显示装置21是开机后首个接收到触控操作的显示装置,则将第一显示装置21确定为主显示装置,并将第二显示装置22确定为副显示装置;若第二显示装置22是开机后首个接收到触控操作的显示装置,则将第二显示装置22确定为主显示装置,并将第一显示装置21确定为副显示装置。
为了区分用户对第一显示装置21和第二显示装置22的触控操作,将用户对第一显示装置21的触控操作称为第一触控操作,将用户对第二显示装置22的触控操作称为第二触控操作。其中,第一触控操作和第二触控操作均可以为单击、双击、滑动、按压等操作。
其中,第一触控信息包括第一显示装置21在开机后首次接收到第一触控操作的第一触控时间,第二触控信息包括第二显示装置22在开机后首次接收到第二触控操作的第二触控时间。
在实际应用中,第一显示装置21会记录其开机后第一次接收到第一触控操作的第一触控时间T1,并将第一触控时间T1发送至第二显示装置22;相应的,第二显示装置22也会其记录开机后第一次接收到第二触控操作的第二触控时间T2,并将第二触控时间T2发送至第一显示装置21。
进一步的,步骤303包括子步骤S11和子步骤S12:
子步骤S11,当所述第一触控时间早于所述第二触控时间时,将所述第一显示装置确定为主显示装置,并将所述第二显示装置确定为副显示装置;
子步骤S12,当所述第一触控时间晚于所述第二触控时间时,将所述第二显示装置确定为主显示装置,并将所述第一显示装置确定为副显示装置。
在实际应用中,当判断第一触控时间T1早于第二触控时间T2时,即确定第一显示装置21是开机后首个接收到触控操作的显示装置,则将第一显示装置21确定为主显示装置,并将第二显示装置22确定为副显示装置;当判断第一触控时间T1晚于第二触控时间T2时,即确定第二显示装置22是 开机后首个接收到触控操作的显示装置,则将第二显示装置22确定为主显示装置,并将第一显示装置21确定为副显示装置。
此外,当第一触控时间T1与第二触控时间T2被判定为同一时刻时,即开机后用户同时触控第一显示装置21和第二显示装置22时,可根据预先设定的优先级顺序,将优先级高的显示装置确定为主显示装置,并将优先级低的显示装置确定为副显示装置;或者,在第一显示装置21和/或第二显示装置22的显示屏中显示提示信息,提示用户选择第一显示装置21和第二显示装置22的主副关系。此处的判定为同一时刻是指第一触控时间和第二触控时间间隔比较近(设置一定的阈值,例如时间间隔为30-100毫秒,具体可以为50毫秒),如果触控间隔为30-100毫秒以内,则处理器判定为是同时触控。
需要说明的是,在第一显示装置21和第二显示装置22开机后,若根据第一显示装置21和第二显示装置22运行的操作系统,和/或,第一显示装置21和第二显示装置22接收到的触控信息,确定了第一显示装置21和第二显示装置22的主副关系之后,则在第一显示装置21和第二显示装置22后续的工作过程中,第一显示装置21和第二显示装置22的主副关系保持不变,只有当第一显示装置21和第二显示装置22关机后再次启动时,才可以重新切换第一显示装置21和第二显示装置22的主副关系。
步骤304,基于所述主副关系,主显示装置发送目标信息至副显示装置,以控制所述副显示装置。
在本申请实施例中,在确定了第一显示装置21和第二显示装置22的主副关系之后,基于该主副关系,主显示装置发送目标信息至副显示装置,以控制副显示装置。其中,目标信息包括第一显示内容、第一操作指令和第二操作指令中的至少一者。
第一种实施方式中,目标信息为第一显示内容;步骤304具体包括子步骤S21:响应于对所述主显示装置的第一触控指令,将所述第一显示内容发送至所述副显示装置上以进行显示,并在所述主显示装置上显示第二显示内容。
在本申请实施例中,在每个显示装置上安装有一个或多个APP (Application,应用程序),每个应用程序通过SDK(Software Development Kit,软件开发工具包)得到,其具有APP协议。应用程序在显示装置的实际运行过程中,需要依赖显示装置上的系统服务才可正常运行,系统服务指的是一种系统后台运行的应用程序类型,可执行指定系统功能的程序、例程或进程,以便支持其他程序,尤其是低层(接近硬件)程序,具体的,应用程序通过ServiceManager接口获取指定的服务,然后通过这个服务来获得硬件服务,从而访问硬件,如硬件中的各种驱动程序。
因此,在确定了第一显示装置21和第二显示装置22的主副关系之后,在主显示装置的桌面上显示有安装的应用程序对应的应用程序图标,用户点击相应的应用程序图标打开应用程序,进行相应的账户登录,以从其他终端中获取相应的内容并进行显示,如点击可支持视频会议的应用程序,进行相应的账户登录后,获取并显示其他终端录制的视频画面以进行视频会议,或者,打开电子白板应用程序,在主显示装置上显示电子白板画面;此外,还可以获取主显示装置上预先存储的内容以进行显示,如显示电子课件等。
当用户在主显示装置上打开并显示第一显示内容时,可在主显示装置上进行触控操作,如单击操作、双击操作、滑动操作、按压操作等,则根据该触控操作生成第一触控指令,然后,响应于对主显示装置的第一触控指令,将第一显示内容发送至副显示装置上以进行显示,并在主显示装置上显示第二显示内容。
例如,用户在主显示装置上打开电子白板画面和电子课件画面,将电子白板画面作为第一显示内容,电子课件画面作为第二显示内容,当主显示装置当前显示的是电子白板画面时,用户在主显示装置上进行滑动操作,且滑动操作的方向为朝向副显示装置的方向,则生成第一触控指令,然后,响应于对主显示装置的第一触控指令,将电子白板画面发送至副显示装置上以进行显示,即此时副显示装置上显示的是电子白板画面,用户可在副显示装置上显示的电子白板画面中进行书写,主显示装置将电子白板画面发送至副显示装置之后,主显示装置可返回至桌面或者直接显示之前打开的电子课件画面,以实现多场景、多内容的同时显示。
需要说明的是,主显示装置向副显示装置发送的第一显示内容是基于 HDMI线发送的,且第一显示内容遵循IIC(Inter-Integrated Circuit,集成电路总线)协议;主显示装置和副显示装置均具有显示功能,且主显示装置上显示的第二显示内容和副显示装置上显示的第一显示内容可以相同(即双屏同显),也可以不同(即双屏异显)。
在确定了第一显示装置21和第二显示装置22的主副关系之后,可基于该主副关系,主显示装置可将第一显示内容发送至副显示装置,即实现两个显示装置之间的数据传输,副显示装置接收主显示装置发送的第一显示内容,并显示该第一显示内容,而主显示装置上可显示第二显示内容。因此,主显示装置可控制副显示装置上显示的内容,而副显示装置无法控制主显示装置上显示的内容。
相对于第一显示装置21和第二显示装置22不连接,独立显示不同的显示内容,本申请通过将第一显示装置21和第二显示装置22连接,实现主显示装置控制副显示装置上显示的内容,用户只需在主显示装置上进行操作,而不需要在两个显示装置上都进行操作,用户的操作更为便利,且可实现主显示装置和副显示装置之间的交互功能,提高了用户的使用效率。
第二种实施方式,目标信息为第一操作指令;步骤304具体包括子步骤S22:响应于对所述主显示装置的第二触控指令,将所述第一操作指令发送至所述副显示装置,以控制所述副显示装置打开或关闭目标应用程序。
在本申请实施例中,在确定了第一显示装置21和第二显示装置22的主副关系之后,用户可在主显示装置和副显示装置上打开相应的应用程序,若用户需要关闭副显示装置上的目标应用程序时,可在主显示装置上进行触控操作,根据该触控操作生成第二触控指令,然后,响应于对主显示装置的第二触控指令,生成第一操作指令,将第一操作指令发送至副显示装置,副显示装置在接收到第一操作指令之后,根据第一操作指令关闭目标应用程序;或者,若用户需要打开副显示装置上的目标应用程序时,可在主显示装置上进行触控操作,根据该触控操作生成第二触控指令,然后,响应于对主显示装置的第二触控指令,生成第一操作指令,将第一操作指令发送至副显示装置,副显示装置在接收到第一操作指令之后,根据第一操作指令打开目标应用程序。因此,本申请实施例还可实现两个显示装置之间的指令传输。
例如,主显示装置根据第一操作指令控制副显示装置打开或关闭可支持视频会议的应用程序。
需要说明的是,第二种实施方式主要适用于第一显示装置21和第二显示装置22当前运行的操作系统均为第二操作系统的情况。
第三种实施方式,目标信息为第二操作指令;步骤304具体包括子步骤S23:响应于对所述主显示装置上设置的显示模式控件的第三触控指令,将所述第二操作指令发送至所述副显示装置,以控制所述副显示装置的显示模式。
在本申请实施例中,在确定了第一显示装置21和第二显示装置22的主副关系之后,用户可在主显示装置上打开显示模式控件对应的界面,用户可对主显示装置上设置的显示模式控件进行触控操作,如点击操作,则根据该触控操作生成第三触控指令,然后,响应于对主显示装置上设置的显示模式控件的第三触控指令,生成第二操作指令,将第二操作指令发送至副显示装置,副显示装置在接收到第二操作指令之后,根据第二操作指令设置自身的显示模式。因此,本申请实施例还可实现两个显示装置之间的指令传输。
其中,显示模式包括第一显示模式和第二显示模式,第一显示模式包括横屏模式和竖屏模式,第二显示模式包括扩展模式和复制模式;当第二显示模式为扩展模式时,第一显示内容与第二显示内容不同,当第二显示模式为复制模式时,第一显示内容与第二显示内容相同。
具体的,显示模式控件包括横屏模式控件、竖屏模式控件、扩展模式控件和复制模式控件,当用户在主显示装置上点击横屏模式控件时,将副显示装置的显示模式设置为横屏模式,当用户在主显示装置上点击竖屏模式控件时,将副显示装置的显示模式设置为竖屏模式,当用户在主显示装置上点击扩展模式控件时,将副显示装置的显示模式设置为扩展模式,当用户在主显示装置上点击复制模式控件时,将副显示装置的显示模式设置为复制模式。
可选的,在设置了副显示装置的显示模式之后,可保存副显示装置的显示模式,当第一显示装置21和第二显示装置22关机后再次开机时,若用户未对主显示装置上设置的显示模式控件进行触控操作,则直接获取上次保存的显示模式,对副显示装置的显示模式进行设置。
需要说明的是,只有在主显示装置当前运行的操作系统为第一操作系统时,才可以对副显示装置的显示模式进行设置,此时,主显示装置为第一显示装置21,副显示装置为第二显示装置22,即第三种实施方式主要适用于第一显示装置21当前运行的操作系统为第一操作系统,第二显示装置22当前运行的操作系统为第二操作系统的情况。
若主显示装置当前运行的操作系统为第二操作系统时,主显示装置没有设置显示模式控件对应的界面,第二显示装置22默认为竖屏模式,第一显示装置21默认为横屏模式;而关于主显示装置上显示的第二显示内容和副显示装置上显示的第一显示内容是相同还是不同,由用户进行控制,即在将第一显示内容发送至副显示装置上显示之后,用户可在主显示装置上进行触控操作,打开第二显示内容,该第二显示内容可以与第一显示内容相同,也可以与第一显示内容不同。
例如,当第一显示内容和第二显示内容不同时,第一显示内容可以为电子白板画面,第二显示内容可以为电子课件画面;当第一显示内容和第二显示内容相同时,第一显示内容和第二显示内容均可以为电子白板画面。
在实际应用中,用户根据使用时的横竖屏需求,对第一显示装置21和第二显示装置22进行相应操作,以设置主显示装置上显示的第二显示内容和副显示装置上显示的第一显示内容的横竖屏模式,以实现多场景、多内容的显示,提高用户的使用体验。
例如,若用户需要两个显示装置显示的内容均为横屏显示,则用户将第一显示装置21当前运行的操作系统设置为第一操作系统,此时,第一显示装置21为主显示装置,并在第一显示装置21上设置第二显示装置22的显示模式为横屏显示,则第一显示装置21上显示的第二显示内容和第二显示装置22上显示的第一显示内容均为横屏显示;或者,若用户需要第一显示装置21显示的内容为横屏显示,第二显示装置22显示的内容为竖屏显示,则用户不对第一显示装置21上的系统设置图标进行触控操作,即第一显示装置21和第二显示装置22均为第二操作系统,选择第一显示装置21作为开机后首次进行触控操作的显示装置,确定第一显示装置21和第二显示装置22的主副关系,后续基于该主副关系在两个显示装置上同时显示第一显 示内容和第二显示内容,且第一显示装置21上显示的第二显示内容为横屏显示,第二显示装置22上显示的第一显示内容为竖屏显示。
在本申请实施例中,通过根据第一显示装置和第二显示装置运行的操作系统,和/或,第一显示装置和第二显示装置接收到的触控信息,确定第一显示装置和第二显示装置的主副关系,基于主副关系,主显示装置发送数据或指令至副显示装置,以控制副显示装置的显示内容、显示模式,以及控制副显示装置打开或关闭目标应用程序。因此,用户只需在主显示装置上进行操作,即可实现两个显示装置的控制,提高用户的使用体验。主显示装置对副显示装置的控制方式并不限于本申请实施例中体现的方案,也可以是本领域技术人员知晓和可以想到的其他方式。
本申请实施例还提供了一种显示控制系统,所述显示控制系统包括第一显示装置21和第二显示装置22,所述第一显示装置21与所述第二显示装置22连接,且所述第一显示装置21和所述第二显示装置22分别具有操作系统,第一显示装置21和所述第二显示装置22的操作系统可以是分别独立的操作系统;所述显示系统还包括处理器;
