具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图对本发明提供的多用途会议终端和多用途会议系统进行详细描述。
图1为本发明的一个实施例提供的一种多用途会议终端的功能框图。如图1所示，所述多用途会议终端包括显示装置12和控制电路16，控制电路16包括无线通信模块161，多用途会议终端通过无线通信模块161与对应的参会者的移动终端进行通信。
本实施例中，无线通信模块161可包括电话呼叫模块、短信收发模块、蓝牙模块、红外模块、GPRS(通用分组无线服务技术)接入模块或者WIFI模块等。相应地，参会者的移动终端也可以具备无线通信功能，以便于实现与多用途会议终端之间的通信。例如：移动终端可包括手机或者平板电脑。在一个具体示例中，每个多用途会议终端对应于一位参会者。
其中，显示装置12用于显示会议信息。本实施例中，会议信息可包括会议相关信息和/或参会者信息，例如参会者的姓名、头衔、所属单位等等，也可以是会议资料、会议日程安排、会议座位号等。会议的主服务器可通过无线传输的方式将与参会者相关的信息发送给多用途会议终端的控制电路，控制电路将与参会者相关的信息发送给显示装置，并由显示装置对与参会者相关的信息进行显示。其中，显示装置可以包括液晶显示装置、OLED显示装置、柔性显示装置或者电子纸显示装置等。
优选地，控制电路16用于通过无线通信模块161与对应的参会者的移动终端建立通信连接，并从移动终端获取存储的终端信息。显示装置12用于对获取的终端信息进行显示。其中，控制电路16可通 过无线通信模块161查找位于附近的移动终端，并从查找出的位于附近的移动终端中确定出对应的参会者的移动终端，从而使得控制电路16可通过无线通信模块161与对应的参会者的移动终端建立通信连接。其中，控制电路16从移动终端获取终端信息的方式可包括：移动终端直接将存储的终端信息推送至控制电路16；或者控制电路16向移动终端发送请求，移动终端在接收到请求后向控制电路16返回终端信息。终端信息可以为移动终端中存储的各种类型的信息，例如：该终端信息可以包括短信、微信或者来电等。这样参会者在参加会议时，可通过多用途会议终端对移动终端上的终端信息进行查看以及编辑。
优选地，多用途会议终端与会议的主服务器进行通信。控制电路16用于接收会议的主服务器发送的服务器信息，并通过无线通信模块161将服务器信息发送至移动终端。其中，服务器信息可以包括各种会议相关信息，例如：会议资料、会议进程和/或会议提醒等。在实际应用中服务器信息还可以包括其他类型的信息，此处不再一一列举。移动终端在接收到服务器信息后可显示该服务器信息。这样参会者在参加会议时，可通过移动终端对多用途会议终端上的服务器信息进行查看以及编辑。
优选地，该多用途会议终端包括人员检测装置17，该控制电路16包括第一判断模块162和记录模块163。人员检测装置17用于获取图像，并将获取的图像发送给第一判断模块162；第一判断模块162用于根据获取的图像判断对应的参会者是否离开，记录模块163用于在第一判断模块162判断出对应的参会者离开时记录会议内容。

下面参照具体实施例对本发明中的多用途会议终端的结构进行示意性而非限制性的说明。
图3为本发明的一个实施例提供的多用途会议终端的示意图。如图3所示，该多用途会议终端包括：显示装置12和设置于显示装置12上的弯折结构(见图5或图12)。显示装置12包括第一显示区域121和第二显示区域122。弯折结构连接在第一显示区域121与第二显示区域122之间，以使得第一显示区域121可相对于第二显示区域122弯折或展平。换句话说，第一显示区域121通过弯折结构活动地连接到第二显示区域122。
图4为图3中的多用途会议终端的弯折状态的示意图。如图4所示，在第一显示区域121相对于第二显示区域122处于弯折状态时，多用途会议终端可以通过相对于彼此弯折的第一显示区域121和第二显示区域122的支撑放置于放置面上。此时第一显示区域121和第二显示区域122用于彼此独立地显示内容信息。第一显示区域121所在面和第二显示区域122所在面之间的夹角可以为设定角度。其中，内容信息可包括第一内容信息和第二内容信息，第一显示区域121可用于显示第一内容信息，第一内容信息可以为会议相关信息，例如：该会议相关信息可以为会议日程或者发表内容；第二显示区域122可用于显示第二内容信息，例如：该第二内容信息可以为参会者姓名、职位等信息。此时，该多用途会议终端可作为电子桌牌供参会者使用。其中，放置面可以为桌面。显示装置12可以包括无边框显示装置和有边框显示装置。图3对应的方案中，显示装置12为有边框显示装置，则该多用途会议终端还包括边框11，该边框11用于固定显示装置12，显示装置12可设置于边框11内。可选地，边框11的用于在多用途会议终端处于弯折状态时与放置面接触的部位设置有防滑垫(图中未示出)，以便于在放置于桌面等放置面时，多用途会议终端的弯折姿态可以保持稳定。
如图3所示，在多用途会议终端处于展平状态时，第一显示区域121和第二显示区域122可以合并为一个显示区域，以使得多用途 会议终端可以用作平板型便携式电子装置，例如平板电脑。优选地，弯折结构被配置为使得在多用途会议终端处于展平状态时第一显示区域121和第二显示区域122位于同一平面内，从而第一显示区域121和第二显示区域122合并为一个显示区域以共同显示一个完整的画面，使得多用途会议终端可以具有较大的显示面积且可以在一个显示区域中显示更多的内容。此时，参会者可以以任意角度手持该多用途会议终端进行操作。
图5为图4中的多用途会议终端的弯折结构的示意图。如图5所示，弯折结构13位于第一显示区域121和第二显示区域122之间。在图3所示的实施例中，弯折结构13设置于边框11上。弯折结构13可以为能够使多用途会议终端折叠的结构。优选地，该弯折结构13为铰链。或者，该弯折结构例如也可以是以柔性材料连接的两块硬性板材。又或者，该弯折结构可以是由多节可相对于彼此变动位置的嵌套起来的硬性部件构成，例如类似于台灯的可变支柱。弯折结构的硬性部分例如可以通过粘接、卡扣、镶嵌等方式与显示装置固定在一起。
在图3所示的实施例中，边框11包括第一子边框111和第二子边框112，第一显示区域121设置于第一子边框111内，第二显示区域122设置于第二子边框112内。第一显示区域121和第二显示区域122为两个分立设置的显示屏，该显示屏可以采用各种类型的显示屏，例如：电子纸显示屏、液晶显示屏或者OLED显示屏等。
优选地，该多用途会议终端还可以包括：第二控制模块、与第一显示区域121同步活动的第一重力传感器和与第二显示区域122同步活动的第二重力传感器。例如，第一重力传感器可设置于第一显示区域121的上边缘，第二重力传感器可设置于第二显示区域122的上边缘。如图5所示，第一显示区域121的上边缘和第二显示区域122的上边缘指的是多用途会议终端弯折并正常放置在放置面上时第一显示区域121和第二显示区域122的位于上部的边缘，即它们各自的被弯折结构相互连接的边缘。第二控制模块、第一重力传感器和第二重力传感器均未在图中示出。
重力传感器能够感知自身的设置方向与重力之间的夹角。第一重力传感器与第二重力传感器分别与第一显示区域和第二显示区域保持固定并可以同步活动，从而第一重力传感器用于检测出第一显示区域121所在面的方向；第二重力传感器用于检测出第二显示区域122所在面的方向。
控制电路用于判断第一显示区域121所在面的方向和第二显示区域122所在面的方向之间的夹角是否大于或者等于设定阈值。若判断出该夹角大于或者等于设定阈值时，控制电路控制第一显示区域121和第二显示区域122上显示的内容信息的画面显示方向相反；若判断出该夹角小于设定阈值时，控制电路控制第一显示区域121和第二显示区域122上显示的内容信息的画面显示方向相同。具体地，第一显示区域121所在面的方向可以以第一显示区域121所在面的法线方向表示，第二显示区域122所在面的方向可以以第二显示区域122所在面的法线方向表示。所述设定阈值可设定为0°至180°之间的任一值，优选地，所述设定阈值可设定为90°至160°之间的任一值。当第二控制模块判断出该夹角大于或者等于设定阈值时，多用途会议终端处于弯折状态。此时该多用途会议终端作为电子桌牌供参会者使用。因此控制电路将第一显示区域121和第二显示区域122上显示的内容信息设置为画面显示方向相反并显示不同的内容信息，以便于使用该多用途会议终端的参会者和其余的参会者能够分别观看第一显示区域121和第二显示区域122的内容信息。这里，“画面显示方向相反”是指在第一显示区域121和第二显示区域122上各自显示的内容信息的画面的顶部(上边缘)均靠近弯折结构，从而当弯折的多用途会议终端正常放置在放置面上时，第一显示区域121和第二显示区域122各自显示的画面均是正立的。当第二控制模块判断出该夹角小于设定阈值时，该多用途会议终端接近或者处于展平状态。此时该多用途会议终端可以作为平板电脑供参会者使用。此时第二控制模块将第一显示区域121和第二显示区域122上显示的内容信息设置为画面显示方向相同并分别显示同一个画面的不同部分。这里，“画面显示方向相同”是指通过第二控制模块的控制使得第一显示区域121上显 示的画面和第二显示区域122上显示的画面能够构成一个完整的画面，以便于参会者观看到该多用途会议终端显示的内容信息是连续的。
图6为图3中的多用途会议终端的收纳状态的示意图，如图6所示，当需要将多用途会议终端收纳时，在第一显示区域121所在面的方向被以第一显示区域121所在面的法线方向的形式表示且第二显示区域122所在面的方向被以第二显示区域122所在面的法线方向的形式表示的情况下，例如，可通过弯折结构将第一显示区域121所在面的方向和第二显示区域122所在面的方向之间的设定角度调整为180°，即将第一显示区域121和第二显示区域122的背面完全贴合。通过设置弯折结构实现了对多用途会议终端的收纳，采用上述收纳方式可节省其存放时占用的空间。
本发明的多用途会议终端可以通过弯折结构在弯折状态和展平状态之间转换。在多用途会议终端处于弯折状态时可以使第一显示区域和第二显示区域彼此独立显示内容信息，并且在多用途会议终端处于展平状态时可以使第一显示区域和所述第二显示区域合并成一个显示区域。因此，提高了用户对多用途会议终端的操作体验，便于收纳，并且节省了其存放时占用的空间。
图7为本发明的另一个实施例提供的多用途会议终端的示意图，图8为图7中的多用途会议终端的收纳状态的示意图。如图7和图8所示，在图3示出的实施例的基础上，图7所示的实施例中的多用途会议终端还可以包括：折叠键盘14，折叠键盘14与第一显示区域121活动连接。在图7所示的实施例中，折叠键盘14与第一显示区域121的一侧的边框活动连接以实现与第一显示区域121活动连接。具体地，该折叠键盘14与第一子边框111活动连接。如图8所示，折叠键盘14用于在折叠状态时保护第一显示区域121。当将多用途会议终端收纳时第一显示区域121的正面朝向外侧，折叠键盘14折叠后会覆盖第一显示区域121的正面，从而实现对第一显示区域121的保护。图9为图7中的多用途会议终端的使用状态的示意图。如图9所示，当需要通过操作折叠键盘14来使用多用途会议终端时，可将 折叠键盘14展开并平放于放置面上以使参会者使用该折叠键盘14。
如图7至图9所示，可选地，该多用途会议终端还可以包括：保护板15，保护板15与显示装置12活动连接，保护板15用于在折叠状态时保护第一显示区域121或者第二显示区域122。图7对应的方案中，保护板15的数量为一个，该保护板15与第二显示区域122的一侧的边框活动连接，具体地，该保护板15与第二子边框112活动连接。当将多用途会议终端收纳时第二显示区域122的正面朝向外侧，保护板15折叠后会覆盖第二显示区域122的正面，从而实现对第二显示区域122的保护。当需要使用多用途会议终端时，保护板15展开，此时保护板15平放于放置面上。
在实际应用中，可选地，保护板15的数量还可以为两个。一个保护板15在折叠状态时保护第一显示区域121，另一个保护板15在折叠状态时保护第二显示区域122。更优选地，可以在保护板15上设置折叠键盘14。
可选地，保护板15上还可以设置充电模块，该充电模块可用于为所述多用途会议终端实时补充能量。
在实际应用中，作为折叠键盘14的替代，该多用途会议终端可包括投影仪、第一控制模块和感测装置。该投影仪可以设置于多用途会议终端上，例如可设置于显示装置12上。投影仪用于在放置面上投影出虚拟键盘；感测装置用于识别参会者在投影出的虚拟键盘上的操作动作；第一控制模块用于将参会者的操作动作一一映射为具体的输入字符或指令，从而获知参会者输入的信息。在放置面之类的物体表面上投影出键盘的图像以实现实际键盘的功能的技术是已知的。该虚拟键盘也可以称为投影键盘，其例如是采用红色激光发射器在物体表面投影出的标准键盘的图像，然后通过红外线技术跟踪手指的动作以实现对输入信息的获取。投影仪、第一控制模块和感测装置在图中未示出。
在多用途会议终端处于弯折状态时，第一显示区域和第二显示区域可以彼此独立显示内容信息。在多用途会议终端处于展平状态时，第一显示区域和第二显示区域合并成一个显示区域。因此，提高 了用户对多用途会议终端的操作体验，并且使得多用途会议终端便于收纳，节省了其存放时占用的空间。当多用途会议终端处于展平状态时，参会者可以将该多用途会议终端作为诸如平板电脑之类的手持式平板电子装置进行操作，并可以任意改变手持该电子装置的角度。
图10为本发明的又一个实施例提供的多用途会议终端的示意图。如图10所示，该多用途会议终端包括：显示装置12和设置于显示装置12上的弯折结构。显示装置12包括第一显示区域121和第二显示区域122。弯折结构设置在第一显示区域121和第二显示区域122之间，使得第一显示区域121可以相对于第二显示区域122弯折或展平。
图10所示出的实施例中，显示装置12为柔性显示屏，第一显示区域121和第二显示区域122一体成型。
图11为图10中的多用途会议终端的弯折状态的示意图。如图11所示，在多用途会议终端处于弯折状态时，多用途会议终端通过第一显示区域121和第二显示区域122的外边缘的支撑而放置于放置面上。此时第一显示区域121和第二显示区域122可以彼此独立地显示内容信息。第一显示区域121所在面和第二显示区域122所在面之间的夹角可以为设定角度。其中，内容信息可包括第一内容信息和第二内容信息，第一显示区域121可用于显示第一内容信息，第一内容信息可以为会议相关信息，例如：该会议相关信息可以为会议日程或者发表内容；第二显示区域122可用于显示第二内容信息，例如：该第二内容信息可以为参会者姓名、职位等信息。此时，该多用途会议终端可作为电子桌牌供参会者使用。其中，放置面可以为桌面。显示装置12可以包括无边框显示装置和有边框显示装置。在图10所示的实施例中，显示装置12为有边框显示装置，即该多用途会议终端还包括边框11，该边框11用于固定显示装置12，显示装置12可设置于边框11内。可选地，边框11的用于在多用途会议终端处于弯折状态下与放置面接触的部位设置有防滑垫(图中未示出)，以便于在放置于桌面等放置面时，多用途会议终端的弯折姿态可以保持稳定。
如图10所示，在多用途会议终端处于展平状态时，第一显示区 域121和第二显示区域122合并成一个显示区域，以使得多用途会议终端可以用作平板型便携式电子装置，例如平板电脑。优选地，弯折结构被配置为使得在多用途会议终端处于展平状态时第一显示区域121和第二显示区域122位于同一平面内，从而第一显示区域121和第二显示区域122合并为一个显示区域以共同显示一个完整的画面，使得多用途会议终端可以具有较大的显示面积且可以在一个显示区域中显示更多的内容。此时，参会者可以以任意角度手持该多用途会议终端进行操作。
图12为图10中的多用途会议终端的弯折结构的示意图，图13为图12中的多用途会议终端的弯折结构的A向视图，图14为图12中的多用途会议终端的展平状态的剖视图。如图12至图14所示，弯折结构13位于第一显示区域121和第二显示区域122之间。图10对应的方案中该弯折结构13设置于边框11上。弯折结构13可以为能够使多用途会议终端折叠的结构。优选地，该弯折结构13为铰链。采用铰链可以确保柔性显示屏在预设的位置进行弯折，而不是随机弯曲成拱桥形，从而便于将多用途会议终端折叠成需要的支架样式。或者，该弯折结构例如也可以是以柔性材料连接的两块硬性板材。又或者，该弯折结构可以是由多节可相对于彼此变动位置的嵌套起来的硬性部件构成，例如类似于台灯的可变支柱。弯折结构的硬性部分例如可以通过粘接、卡扣、镶嵌等方式与显示装置固定在一起。
可以将弯折结构13设置为在多用途会议终端处于展平状态时与显示装置12的显示面之间具有设定距离。也就是说，如图14所示，在多用途会议终端处于展平状态时，显示装置12的显示面高于弯折结构13的最高点，这样在多用途会议终端处于弯折状态时显示装置12的显示面与弯折结构13之间具有一定的空间余量，从而避免由于张力过大而造成显示装置的屏幕(即，显示面)损坏以及显示画面失真的问题。
优选地，该多用途会议终端还可以包括：第二控制模块、与第一显示区域121同步活动的第一重力传感器和与第二显示区域122同步活动的第二重力传感器。例如，第一重力传感器可设置于第一显 示区域121的上边缘，第二重力传感器可设置于第二显示区域122的上边缘。如图5所示，第一显示区域121的上边缘和第二显示区域122的上边缘指的是多用途会议终端弯折并正常放置在放置面上时第一显示区域121和第二显示区域122的位于上部的边缘，即它们各自的被弯折结构相互连接的边缘。第二控制模块、第一重力传感器和第二重力传感器均未在图中示出。
重力传感器能够感知自身的设置方向与重力之间的夹角。第一重力传感器与第二重力传感器分别与第一显示区域和第二显示区域保持固定并可以同步活动，从而第一重力传感器用于检测出第一显示区域121所在面的方向；第二重力传感器用于检测出第二显示区域122所在面的方向。
控制电路用于判断第一显示区域121所在面的方向和第二显示区域122所在面的方向之间的夹角是否大于或者等于设定阈值。若判断出夹角大于或者等于设定阈值，则控制电路控制第一显示区域121和第二显示区域122上显示的内容信息的画面显示方向相反。若判断出夹角小于设定阈值，则控制电路控制第一显示区域121和第二显示区域122上显示的内容信息的画面显示方向相同。具体地，第一显示区域121所在面的方向可以以第一显示区域121所在面的法线方向表示，第二显示区域122所在面的方向可以以第二显示区域122所在面的法线方向表示。所述设定阈值可设定为0°至180°之间的任一值，优选地，所述设定阈值可设定为90°至160°之间的任一值。当第二控制模块判断出该夹角大于或者等于设定阈值时，多用途会议终端处于弯折状态。此时该多用途会议终端作为电子桌牌供参会者使用，因此控制电路将第一显示区域121和第二显示区域122的内容信息设置为画面显示方向相反并显示不同的内容信息，以便于使用该多用途会议终端的参会者和其余的参会者能够分别观看第一显示区域121和第二显示区域122的内容信息。当第二控制模块判断出该夹角小于设定阈值时，该多用途会议终端接近或者处于展平状态。此时该多用途会议终端可以作为平板电脑供参会者使用。此时，第一显示区域121和第二显示区域122被看作一个显示区域。第二控制模块将第一显示 区域121和第二显示区域122上显示的内容信息设置为画面显示方向相同并分别显示同一个画面的不同部分，以便于参会者观看到该多用途会议终端显示的内容信息是连续的。
