具体实施方式
下面将结合附图，对本公开实施例提供的一种显示装置及其驱动方法的具体实施方式进行详细地说明。需要说明的是，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本公开实施例提供的一种显示装置，参见图1和图2所示，其中，图1为图2的截面示意图，显示装置包括：
透明盖板1；
显示模组，显示模组位于透明盖板1的一面，包括第一显示模组21和第二显示模组22，第一显示模组21和第二显示模组22具体可以进行独立控制显示，例如，可以仅使第一显示模组21进行显示，也可以仅使第二显示模组22进行显示，也可以使第一显示模组21和第二显示模组22同时进行显示；
第一显示控制电路31，第一显示控制电路31位于显示模组的背离透明盖板1的一面，被配置为独立控制第一显示模组21；例如，第一显示控制电路31独立控制第一显示模组21显示会议画面；
第二显示控制电路32，第二显示控制电路32位于显示模组的背离透明盖板1的一面，被配置为独立控制第二显示模组22；例如，第二显示控制电路32独立控制第二显示模组22显示用户输入的会议的记录信息。
可选地，在本公开实施例提供的上述显示装置中，第一显示控制电路31可以与第二显示控制电路32电连接；
第一显示控制电路31，还被配置为向第二显示控制电路32发送控制信号；
第二显示控制电路32，还被配置为响应于控制信号控制第二显示模组22配合第一显示模组21进行相应的显示。
例如，在进行会议展示时，需要第一显示模组21和第二显示模组22相互配合构成一完整的显示区域，以显示在会议过程中的一段视频或图片，此时，第一显示控制电路31可以向第二显示控制电路32发送相应的控制信号，使第二显示控制电路32控制第二显示模组22配合第一显示模组21进行同步显示，即第一显示模组21显示图片中的一部分区域或显示视频中图像的一部分区域，第二显示模组22显示图片中的另一部分区域或显示视频中图像的另一部分区域，构成一完整图片或视频。
具体地，本公开实施例提供的上述显示装置中，第一显示控制电路31可以对第一显示模组21进行独立控制，第二显示控制电路32可以对第二显示模组22进行独立控制，可以通过第一显示模组进行显示，在第二显示模组进行记录，双屏可以同步显示，也可以独立显示，使显示装置用于会议装置时具有较高的利用效率。
在具体实施时，在本公开实施例提供的上述显示装置中，参见图3所示，第一显示控制电路31可以包括：第一显示主板311，第一显示主板311内可以安装有安卓系统；主机部件312，主机部件312内可以安装有Windows系统，主机部件312包括信号输出接口A，其中，主机部件312具体可以为开放式可插拔主机(Open Pluggable Specification，OPS)部件，信号输出接口A具体可以为高清多媒体接口(High Definition Multimedia Interface，HDMI)；
第二显示控制电路32可以包括：第二显示主板321，第二显示主板321内可以安装有安卓系统，包括信号输入接口B，第二显示主板321的信号输入接口B与主机部件312的信号输出接口A电连接，其中，信号输入接口B具体可以为HDMI输入接口B；
第二显示主板321被配置为响应于主机部件321发送的控制信号，控制第二显示模组22配合第一显示模组21进行相应的显示。
具体地，在第一显示控制电路31接收到用户指示的同步显示指令后，将第一显示模组21从采用第一显示主板311进行驱动切换为采用主机部件312进行驱动，同时控制主机部件312向第二显示主板321发送该控制信号；第二显示主板321接收主机部件312的控制信号后，根据该控制信号控制第二显示模组22的显示内容。例如，可以将第一显示模组21的内容扩展到第二显示模组22上，即，第一显示模组21和第二显示模组22作为一个整体的显示屏进行显示，或者，可以控制第二显示模组22显示与第一显示模组21相同的显示内容，即，第二显示模组22复制第一显示模组21的显示内容。
需要说明的是，OPS全称为：Open Pluggable Specification，开放式可插拔规范，是Intel与显示器厂商共同制定的标准化数字标牌接口规范。OPS内部组成是一个X86架构的迷你PC，采用英特尔酷睿处理器，配有内存、硬盘、多种输入输出接口以及Windows操作界面。在本发明实施例中，主要是为了实现功能扩展。一方面，本公开实施例虽然在无OPS的情况下也可满足日常会议显示需求，但是在文稿撰写和大型软件运行时(如CAD，3D建模等)会遇到瓶颈，在这种情况下，就需要选配一个OPS电脑来丰富扩展其功能。另 一方面，本公开实施例也可通过OPS来实现主副屏互动显示功能，OPS模块HDMI输出与副屏主板(第二显示控制电路32)HDMI输入用HDMI线连接在一起。即可将OPS内容传输到副屏(第二显示模组22)上，当主屏(第一显示模组21)切换至OPS模式(Windows系统)，副屏切换至HDMI通道，即可实现主、副屏同时显示使用，可将主屏显示的内容扩展到副屏上，也可将主屏内容复制到副屏上，实现双屏互动。另外，在具体实施时，由于本发明实施的主要操作系统为安卓系统，第一显示主板311和第二显示主板321采用安卓系统可以节省成本。但市面上很多应用软件特别是一些大型软件无法很好地运行在安卓系统上，故而需要OPS部件的Windows系统来对本装置的功能进行补充和增强。
具体地，在本公开实施例提供的上述显示装置中，采用安装有Windows系统的主控部件312同时控制第一显示模组21和第二显示模组22的显示，可以避免采用第一显示主板311直接控制第二显示主板321时，由于第一显示主板311和第二显示主板321均安装有相同的操作系统，第二显示模组22无法区分两个主板发送的信号区别，导致第二显示模组22失控而无法工作的问题。而通过OPS来控制第二显示主板321，当第一显示模组21切换至OPS驱动时，第二显示模组21只需切换到HDMI通道，即可实现与第一显示模组21的同步显示。若第二显示模组21不切换通道，由于第二显示主板321本身安装有安卓系统，也可独立显示。另外，通过OPS来控制第二显示主板321实现方式较为方便，只需通过一条HDMI通道即可将OPS与第二显示主板321连接，不用对第一显示主板311和第二显示主板321的软件进行复杂的修改。
在具体实施时，在本公开实施例提供的显示装置中，第二显示主板321被配置为响应于用户的切换指令，切换到第二显示主板321驱动第二显示模组22时，断开与主机部件312的通信，独立控制第二显示模组22，以使第一显示控制电路31与第二显示控制电路32相互独立工作。
本公开实施例中，第二显示控制电路32为切换到第二显示主板321驱动的安卓系统时，可以实现第一显示控制电路31与第二显示控制电路32的断 开，具体的，可以通过软件来实现断开，软件通过切换不同的信号通道来实现对应功能的切换，如切换到安卓通道时，副屏独立工作；切换到HDMI通道时，副屏可与主屏同时使用，进而可以使第一显示模组21和第二显示模组22独立工作。
在具体实施时，参见图3所示，第一显示控制电路31还包括：第一显示驱动板313，例如可以是T-CON；第一显示主板311通过第一显示驱动板313向第一显示模组21发送显示信号，以控制第一显示模组21显示；第二显示控制电路32还包括：第二显示驱动板323，例如可以是T-CON；第二显示主板321通过第二显示驱动板323向第二显示模组22发送显示信号，以控制第二显示模组22显示，其中，显示信号具体可以是经过处理后的图像信号，即将第一显示控制电路31发送的图像数据信号、时钟信号等转换成第一显示模组21所需要的行列驱动等数字信号，驱动液晶屏显示图像。
在具体实施时，参见图3所示，第一显示控制电路31可以包括：与主机部件312电连接的主机转接板314；主机部件312通过主机转接板314与第一显示主板311电连接。
在具体实施时，参见图3所示，第一显示控制电路31还可以包括：第一显示电源板315，第一显示电源板315与第一显示主板311、主机转接板314均电连接，为第一显示主板311、主机转接板314供电；第二显示控制电路32还可以包括：第二显示电源板325，第二显示电源板325与第二显示主板321电连接，为第二显示主板321供电。

本公开实施例中，第一显示控制电路31包括红外遥控接收部件316，第二显示控制电路32包括蓝牙遥控接收部件326，即，第一显示控制电路32与第二显示控制电路32的遥控接收部件的类型不同，可以避免会议第一显示控制电路32或第二显示控制电路32在接收遥控信号时的相互干扰。
在具体实施时，参见图3所示，第一显示控制电路31以及第二显示控制 电路32还可以均设置有喇叭316。

在具体实施时，参见图4所示，显示装置还包括：包围透明盖板1边缘的型材框架6；第二显示模组22与型材框架6之间具有间隙区域；显示装置在间隙区域具有副屏支架；副屏支架包括与透明盖板1延伸方向相同的支架主体71，支架主体71的一端通过第二固定部件52与型材框架6固定，第二固定部件52具体可以为螺丝，另一端具有沿垂直于支架主体71延伸方向延伸的第一垂直部72；第一垂直部72与第二显示模组22的一端接触，用于对第二显示模组22进行限位固定。本公开实施例中，显示装置还包括型材框架6，支架主体71，其中，型材框架6可以对透明盖板1进行限位，支架主体71的第一垂直部72，可以实现对第二显示模组22的限位固定，进而可以通过副屏支架实现将第二显示模组22与透明盖板1、型材框架6进行相互组装固定，而且，副屏支架较为轻薄，可以在使第二显示模组22与透明盖板1、 型材框架6进行相互固定的同时，实现显示装置的轻薄化。
在具体实施时，参见图4所示，副屏支架还包括沿垂直于支架主体71延伸方向延伸的第二垂直部73，第二垂直部73位于第一垂直部72的面向型材框架6的一侧；第二显示模组压板4还包括位于第一垂直部72和第二垂直部73之间的弯折部41，以及与弯折部41的端部连接且沿支架主体71延伸方向延伸的固定部42，固定部42在与第二垂直部73对应的位置具有第二过孔；第二垂直部73穿过第二过孔，通过第三固定部件53与固定部42固定，第三固定部件53具体可以为螺帽。本公开实施例中，副屏支架还包括第二垂直部73，第二显示模组压板4还包括固定部42，固定部42可以穿过第二垂直部73，进而实现将第二显示模组压板4与副屏支架进行组装固定，进一步实现将电路板3与第二显示模组22、透明盖板1、型材框架6进行一体固定，而且，通过固定部42穿过第二垂直部73的方式将第二显示模组压板4与副屏支架进行固定的方式，较为简单且较为牢固，有利于显示装置实现轻薄化。
在具体实施时，参见图4所示，显示装置还包括位于电路板3的背离透明盖板一面的壳体，壳体包括：壳体主体81，以及位于壳体主体81端部且向电路板3一侧延伸的壳体弯折部82；型材框架6还包括向远离透明盖板1一侧延伸的型材框架延伸部61，型材框架延伸部61与壳体弯折部82在重叠的位置处通过第四固定部件54固定，第四固定部件54可以为螺丝。本公开实施例中，显示装置还包括位于电路板3的背离透明盖板一面的壳体，壳体包括壳体弯折部82，型材框架6还包括型材框架延伸部61，壳体弯折部82型材框架延伸部61重叠，进而可以通过第四固定部件54将其二者进行相互固定，进一步可以实现将型材框架6、副屏支架、第二显示模组压板4与壳体固定，而且，通过型材框架延伸部61与壳体弯折部82在重叠位置处进行固定，二者的固定方式结构简单，节省空间。
在具体实施时，参见图5所示，第一显示模组21的侧端与壳体弯折部82、型材框架延伸部61相对，通过第五固定部件55固定，第五固定部件55可以为螺丝。在具体实施时，第一显示模组21可以作为主显示模组，第二显示模 组22可以作为副显示模组，由于主显示模组的尺寸较大，需要的设置空间也相应较大，因此，可以将电路板3设置在于副显示模组对应的位置处，进而在主显示模组处，可以仅直接通过第五固定部件，将壳体主体81、第一显示模组21、型材框架6进行一体固定。而且，电路板3设置在与第二显示模组22对应的位置处，也有利于显示装置的在不同的位置的重量均衡分布。
