具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
这里用于描述本公开的实施例的术语并非旨在限制和/或限定本公开的范围。例如，除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。应该理解的是，本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。除非上下文另外清楚地指出，否则单数形式“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包括”或者“包 含”后面列举的元件或者物件及其等同，并不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则所述相对位置关系也可能相应地改变。
在拼接显示装置中，承载箱体用于承载至少一个显示组件。在一个示例中，显示组件可以包括：托架及其承载的显示基板。托架固定在承载箱体上，显示基板固定在托架远离承载箱体的一侧。显示基板可以包括衬底基板和设置在衬底基板上的发光件。衬底基板可以采用玻璃基板，发光件可以包括微型无机发光二极管。在另一个示例中，显示组件同样可以包括显示基板，该显示基板包括：印刷电路板和设置在印刷电路板上的发光件，发光件可以包括微型无机发光二极管。这种情况下，显示基板可以直接固定在承载箱体上。
进一步地，在拼接显示装置中，显示基板的数量可以为多个，多个显示基板相互拼接，从而可以形成拼接显示。例如，在拼接显示装置中，承载箱体的数量为一个，该承载箱体上承载有多个显示基板；又例如，承载箱体的数量为多个，每个承载箱体上承载有一个或多个显示基板。
在拼接显示装置的组装过程中，将显示组件固定在承载箱体上之后，由于生产工艺的限制，很容易出现多个显示基板的显示面不在同一平面上的情况，此时就需要在显示基板的厚度方向上，对显示组件进行调节，直至多个显示基板的显示面位于同一平面上。
图1为本公开的一些实施例中提供的承载箱体的示意图，图2为本公开的一些实施例中提供的承载箱体与显示组件装配前的示意图，图3为本公开的一些实施例中提供的拼接显示装置的示意图，图4为本公开的一些实施例中提供的显示组件的后视图，图5为本公开实施例中提供的拼接显示装置的局部剖视图。如图1至5所示，承载箱体100包括：箱体主体110 和设置在箱体主体110上的调节件120。
其中，箱体主体110用于承载至少一个显示组件200，显示组件200可以包括至少一个显示基板。图2中仅以箱体主体110承载了8个显示组件200为例进行说明，在其他示例中显示组件200的数量可以为其他数量。例如，箱体主体110可以承载一个显示组件200，显示组件200包括一个显示基板，多个箱体主体110拼接，从而共同承载多个显示基板，实现拼接显示。又例如，箱体主体110可以承载多个显示组件200，显示组件200包括一个或多个显示基板。
如图4和图5所示，显示组件200朝向箱体主体110的一侧设置有固定部240，该固定部240用于与调节件120连接。
图6为本公开的一些实施例中提供的调节件的分解示意图，如图6所示，调节件120包括：磁性部122以及与磁性部122相连的调节部121，磁性部122用于与固定部240连接，调节部121用于在磁性操作件的操作下，沿Z方向(即，显示基板的厚度方向)相对于箱体主体110移动，以调节固定部240与箱体主体110之间的距离。
需要说明的是，所谓的“磁性操作件”并不一定表示，操作件整体是磁性的，只要是操作件的一部分具有磁性，从而能够带动调节件120沿Z方向相对于箱体主体110移动即可。
在本公开实施例中，调节件120在磁性操作件的操作下，可以沿Z方向相对于箱体主体110移动，从而带动显示组件200的相应位置沿Z方向相对于承载箱体100移动，进而可以调节显示基板显示面上的各位置到参考平面的距离，直至各个显示基板的显示面位于同一平面上。并且，调节件120中的磁性部122与固定部240连接，因此，即使磁性部122与磁性操作件300之间被显示组件200间隔开，也可以通过磁性操作件与磁性部122之间的磁力，来带动调节件120移动，而无需将显示组件200与承载箱体100拆分开，从而防止拆卸过程中对显示组件200造成磕碰，并且，在 调节过程中，操作人员可以更直观地判断出调节结果是否达到要求，从而有利于提高调节效率。
图7为本公开的一些实施例中提供的磁性操作件的示意图，图8A为本公开的一些实施例中提供的通过磁性操作件来控制调节件移动的示意图，图8B为本公开的一些实施例中提供的通过磁性操作件来控制调节件移动的局部立体图，图8C为本公开的一些实施例中提供的通过磁性操作件来控制调节件移动的另一个局部立体图，图8C中为了更清楚地示意出磁性操作件300与调节件120的位置关系，隐去了显示组件200。如图7至图8C所示，磁性操作件300包括：握持部310、连接部320和操作头部330，连接部320的一端与握持部310连接，连接部320的另一端与操作头部330连接。连接部320可以与握持部310形成为一体结构，以提高结构稳定性。当然，连接部320也可以通过其他连接方式与握持部310固定连接。例如，通过螺丝等紧固件将二者连接。
操作头部330与磁性部122相互靠近的两端的极性可以相反(即，操作头部330与磁性部122相互靠近的两端的极性分别设置为N极和S极)，从而在二者相互靠近时，可以相互吸引。
在一些实施例中，操作头部330可以包括固定座332和固定在固定座332上的第一磁块331。例如，固定座332上设置有固定槽332v，第一磁块331固定在固定槽332v中。其中，第一磁块331可以为永磁体，其磁化方向为轴向。示例性地，第一磁块331的主体材质可以为钕铁硼强磁，且第一磁块331可以由镍铜镍进行表面处理。
在一些实施例中，第一磁块331的形状与固定槽332v的形状相匹配，例如，第一磁块331在固定做上的正投影以及固定槽332v的横截面均为圆形、方形、一字型、十字形、米字形等，第一磁块331的厚度与固定槽332v的深度可以相同或相近。
其中，第一磁块331可以嵌入固定槽332v中，也可以在固定槽332v 中设置粘结胶，从而进一步提高第一磁块331在固定槽332v中的设置稳定性。
在一些实施例中，固定座332远离握持部310的端部设置有第一缺口332s，该第一缺口332s与固定槽332v连通。其中，第一缺口332s的数量可以为多个，例如为两个，两个第一缺口332s相对设置，当然，第一缺口332s的数量也可以为三个、四个或其他更多数量。在产品维护的过程中，若需要将第一磁块331从固定座332中取出，则可以利用夹具，将其伸入第一缺口332s中，从而将第一磁块331夹持取出。在一个示例中，固定座332与连接部320螺纹连接。这种情况下，在将固定座332与连接部320连接时，可以利用工具伸入第一缺口332s中，并带动固定座332与连接部320之间发生相对旋转，从而使固定座332上的螺纹与连接部320上的螺纹咬合。当然，固定座332与连接部320也可以采用不可拆卸的连接方式，例如焊接，或固定座332与连接部320形成为一体结构。
当然，在其他实施例中，也可以不设置固定座332，而是直接将连接部320与第一磁块331固定连接，例如，第一磁块331与连接部320螺纹连接。
在本公开实施例中，对握持部310的形状不作限定，例如，如图7所示，握持部310可以包括弧形部和直线部，弧形部的两端分别与直线部的两端连接，直线部的中部与连接部320连接。当然，握持部310也可以为其他形状。例如，握持部310为圆环状。
在一些实施例中，如图6和图8A所示，调节部121包括螺杆，箱体主体110上设置有与螺杆匹配的螺纹孔113v，螺杆的至少一部分设置在螺纹孔113v中。
在通过磁性操作件300来控制调节件120移动时，如图8A至图8C所示，将磁性操作件300的操作头部330与调节件120相对设置，如上文所述，磁性操作件300的操作头部330与磁性部122的极性相反，因此，操作头部330与磁性部122之间相互吸引。此时，通过转动磁性操作件300， 从而带动调节件120同步旋转，进而使调节件120沿Z方向相对于箱体主体110移动。
在一些实施例中，如图6所示，磁性部122包括：安装座122a和第二磁块122b，第二磁块122b固定在安装座122a上，安装座122a与调节部121连接。例如，安装座122a与调节部121为一体结构，从而在调节件120的旋转过程中，安装座122a与调节部121始终保持固定连接。
在一些实施例中，如图6所示，安装座122a上设置有安装槽122v，第二磁块122b固定在安装槽122v中。其中，第二磁块122b可以为永磁体，其磁化方向为轴向。示例性地，第二磁块122b的主体材质可以为钕铁硼强磁，且第二磁块122b可以由镍铜镍进行表面处理。当第一磁块331和第二磁块122b均采用强磁材料时，操作头部330与磁性部122之间可以产生较强的磁力，从而保证调节件120可以随磁性操作件300同步转动。
在一些实施例中，第二磁块122b的形状与安装槽122v的形状相匹配，例如，第二磁块122b在安装座122a上的正投影、安装槽122v的横截面均为圆形、方形、一字型、十字形、米字形等，第二磁块122b的厚度与安装槽122v的深度可以相同或相近。其中，第二磁块122b在安装座122a上的正投影为一字型是指，第二磁块122b在安装座122a上的正投影为条状，即圆角长方形或直角长方形；第二磁块122b在安装座122a上的正投影为十字形是指，第二磁块122b在安装座122a上的正投影为两个条状部交叉形成的图形。当然，第二磁块122b在安装座122a上的正投影也可以为更多数量的条状部交叉形成的图形，例如米字形。
另外，在实际应用中，第二磁块122b的形状可以与第一磁块331相同，从而在第一磁块331与第二磁块122b之间产生稳定的磁场。在一个示例中，第一磁块331在固定座332上的正投影、第二磁块122b在安装座122a上的正投影均为十字形。
其中，第二磁块122b可以嵌入安装槽122v中，也可以在安装槽122v 中设置粘结胶，从而进一步提高第二磁块122b在安装槽122v中的设置稳定性。
在一些实施例中，如图6所示，安装座122a朝向显示基板的端部设置有第二缺口122s，该第二缺口122s与安装槽122v连通。其中，第二缺口122s的数量可以为多个，例如为两个，两个第二缺口122s相对设置，当然，第二缺口122s的数量也可以为三个、四个或其他更多数量。在产品维护的过程中，若需要将第二磁块122b从安装座122a中取出，则可以利用夹具的夹头，将其伸入第二缺口122s中，从而将第二磁块122b夹持取出。
在一些实施例中，如图6所示，磁性部122包括一个第二磁块122b，这种情况下，调节部121的轴线的延长线穿过第二磁块122b，以便于控制调节件120整体的旋转。例如，第二磁块122b的中心轴线与调节部121的轴线位于同一直线上。
需要说明的是，图6是以磁性部122包括一个第二磁块122b为例进行示意的，在另一些实施例中，磁性部122也可以包括多个第二磁块122b，其中，多个第二磁块122b的极性可以相同。安装座122a上可以设置有多个安装槽122v，第二磁块122b一一对应地设置在安装槽122v中。例如，第二磁块122b和安装槽122v的数量均为三个，或均为四个，或者其他数量。多个第二磁块122b的大小和形状均可以相同。另外，多个第二磁块122b环绕调节部121轴线的延长线均匀分布，从而在利用外部的磁性操作件300驱动调节件120转动时，各个第二磁块122b的受力大致相同，进而使调节件120可以平稳地旋转。
当磁性部122包括多个第二磁块122b时，利用外部的磁性操作件300来驱动调节件120转动时，旋转扭矩较大，操作更加便捷。
另外，当磁性部122包括多个第二磁块122b时，相应地，磁性操作件300也可以包括多个第一磁块331，多个第一磁块331的极性相同，且与多个第二磁块122b的极性相反。第一磁块331的数量和分布方式可以与第二 磁块122b相同，即，多个第一磁块331围绕连接部320轴线的延长线均匀分布。当利用磁性操作件300来驱动调节件120转动时，第二磁块122b与第一磁块331一一对应地相吸附。
在一些实施例中，如图5所示，箱体主体110包括：底壁112以及与底壁112连接的侧壁111，底壁112与侧壁111限定出容纳空间，底壁112上还可以设置有至少一个支撑台113，支撑台113位于容纳空间内。其中，支撑台113具有与底壁112连接的第一表面、朝向显示基板200的第二表面、以及连接在第一表面和第二表面之间的侧面，部分支撑台113的侧壁与箱体主体110的侧壁111相互抵靠，在一个示例中，支撑台113与侧壁111可以为一体结构。螺纹孔113v设置在支撑台113的第二表面上。
在一些实施例中，如图5所示，箱体主体110的底壁112上还可以设置有多个加强筋115，从而提高底壁112的稳定性。其中，加强筋115的形状和尺寸可以根据实际需要进行灵活设置。
在一些实施例中，如图1和图5所示，箱体主体110的侧壁111上还可以设置有定位件114，定位件114用于与相邻的箱体主体110进行定位。例如，在拼接显示装置的相邻两个箱体主体110中，箱体主体110的侧壁上均设置有定位件114，其中一个箱体主体110上的定位件114可以为定位柱，另一个箱体主体110上的定位件114可以为定位槽。当然，相邻两个箱体主体110上的定位件114可以采用其他形式进行定位。
图9为本公开的一些实施例中提供的调节件在箱体主体上的分布示意图，如图9所示，在一些实施例中，箱体主体110具有至少一个或多个承载区Q，每个承载区Q对应一个显示组件200。图9中是以8个承载区Q为例进行示意说明的，在实际生产应用中，承载区Q的数量可以为其他数量。示例性地，显示组件200为矩形结构，相应地，承载区Q为矩形区域。对于每个承载区Q而言，在该承载区Q的每个边角位置均设置有调节件120，从而便于对显示组件200显示面上各位置与参考平面之间的距离进行调节。 当然，在承载区Q的其他位置也可以设置安装孔，例如，在靠近承载区Q边缘且位于两个边角之间的位置，也可以设置有一个或多个调节件120。在承载区Q的同一侧边上，相邻两个调节件120之间的距离可以为侧边长度的1/4～1/3，或者1/3～1/2，或者1/2～5/6。
在一些实施例中，承载箱体100还包括：固定在箱体主体110上的主控电路板、接收电路板和电源模块。其中，主控电路板130、接收电路板(未示出)和电源模块140均可以设置在容纳部中。例如，主控电路板130、接收电路板和电源模块140均可以通过粘结件或螺丝等结构固定在箱体主体110上。另外，主控电路板130、接收电路板、电源模块140在箱体主体110的底壁112上的正投影与调节件120在底壁112上的正投影均无交叠。接收电路板用于接收视频源信号，并根据视频源信号为主控电路板130输出显示驱动信号。其中，视频源信号为与所述拼接显示装置的显示内容相对应的信号。电源模块140被配置为根据电压源信号(例如，220V的电压信号)，对电压源信号进行电压转换，并根据转换后的电压，为主控电路板130提供目标电信号。其中，目标电信号为主控电路板130正常工作所需要的电信号。主控电路板130与显示组件200电连接，被配置为根据显示驱动信号和目标电信号，为显示组件200提供控制信号，以控制显示组件200进行显示。
其中，电压源信号和视频源信号可以通过传输线分别提供至接收电路板和电源模块140，相应地，如图1和图5所示，箱体主体110的侧壁上设置有通孔V1，传输线可以穿过通孔V1，从而为接收电路板、电源模块140提供信号。
本公开实施例还提供一种拼接显示装置，如图3和图5所示，拼接显示装置包括：显示组件200以及用于承载显示组件200的承载箱体100，该承载箱体100采用上述实施例中的承载箱体100。
其中，显示组件200朝向箱体主体110的一侧设置有固定部240，磁性 部122与固定部240连接。
在一些实施例中，如上文所述，调节件120的调节部121包括与螺纹孔113v配合的螺杆，从而通过旋转螺杆，来实现调节件120在Z方向上的移动。这种情况下，固定部240的材料包括铁磁性材料，需要说明的是，铁磁性材料是指，能够与磁铁相吸附的材料，从而使固定部240与磁性部122通过磁性吸附的方式连接。例如，固定部240包括铁块。可以理解的是，当利用磁性操作件300来驱动某一个调节件120旋转时，由于其他调节件120仍保持与磁性部122的吸附状态，因此，调节件120转动时，仅能带动显示组件200在Z方向发生移动，而并不会导致显示组件200发生旋转。
在本公开实施例中，对固定部240的形状不作限定，例如，固定部240可以为圆形板状结构，或者矩形板状结构，或者，固定部240的形状与第二磁块122b的形状相同。在一些实施例中，固定部240在显示组件200上的正投影覆盖第二磁块122b在显示组件200上的正投影，这样，在产品组装过程中，即便出现对位偏差，也可以保证固定部240与第二磁块122b的稳定吸附。例如，结合图4和图5所示，固定部240可以为圆形板状结构，固定部240的厚度可以为第二磁块122b厚度的1/4～2倍。例如，固定部240的厚度为第二磁块122b厚度的1/4倍，或1/2倍，或1倍。
为了防止铁块在拼接显示装置的使用过程中被氧化，在一些实施例中，固定部240除了包括铁块之外，还包括防氧化层，防氧化层覆盖铁块的至少部分表面。例如，铁块包括与显示组件接触的连接面，铁块表面上除连接面之外的部分均覆盖有防氧化层。防氧化层例如为镀镍层。
图10为本公开的一些实施例中提供的显示组件的示意图，如图10所示，显示组件200包括：显示基板210和托架220。图11为本公开的另一些实施例中提供的显示基板的示意图，如图11所示，显示基板210包括：衬底基板210a和设置在该衬底基板210a上的发光件210b，发光件210b位于衬底基板210a远离箱体主体110的一侧。其中，衬底基板210a可以为玻 璃基板，发光件210b可以为微型发光二极管等。另外，显示基板210还可以包括设置在衬底基板210a上的保护层210c，保护层210c至少位于相邻的发光件210b之间的区域。在一些示例中，保护层210c还可以覆盖发光件210b远离衬底基板210a的表面。保护层210c可以为包括炭黑粒子的膜层，这种情况下，保护层210c对应于发光件210b的位置应当具有一定的透光率，以防止影响发光件210b的出光。通过保护层210c的设置，可以提高显示基板210显示画面的对比度。
如图10所示，托架220位于显示基板210与箱体主体之间，其中，显示基板210的衬底基板210a与托架220固定连接，托架220上可以固定有一个显示基板210，也可以固定有多个显示基板210，图10中示意出了一个托架220用于固定一个显示基板210的情况。如图10所示，显示基板210的衬底基板210a可以通过粘结件BL固定在托架220上。固定部240固定在托架220朝向箱体主体的一侧，从而通过固定部240与调节件的连接，将托架220与承载箱体100连接。
另外，如图10所示，显示组件200还可以包括：柔性线路板231和驱动电路板232，其中，托架220可以包括底板221以及与该底板221连接的侧板222，底板221具有朝向显示基板210的承载面和背离显示基板210的安装面，承载面用于固定显示基板210，驱动电路板232设置在安装面上。驱动电路板232的一端与箱体主体110上的主控电路板连接，驱动电路板232的另一端与显示基板210通过柔性线路板231实现电连接。托架220的底板221上设置有镂空部V，柔性线路板231的一部分与显示基板210电连接，另一部分穿过镂空部V与驱动电路板232连接。
柔性线路板231与显示基板210电连接是指，柔性线路板231与发光件210b电连接。具体地，衬底基板210a上设置有第一绑定电极和第二绑定电极，第一绑定电极位于衬底基板210a背离发光器件的一侧，第二绑定电极与发光件210b位于衬底基板210a的同一侧，第一绑定电极通过信号 线与发光件210b连接，第二绑定电极通过连接线与第一绑定电极连接，柔性线路板231一端的绑定区与第一绑定电极连接，柔性线路板231的另一端与驱动电路板232上的连接器232a连接。在一些示例中，显示基板210的非显示侧设置有三个柔性线路板231，该三个柔性线路板231与驱动电路板232上的连接器232a一一对应连接。其中，连接线的一部分可以位于衬底基板210a的侧面，这种情况下，当多个显示基板210进行拼接显示时，相邻显示基板210之间的拼接缝宽度较小。
在一些示例中，主控电路板130上设置有第一连接器132，驱动电路板232上设置有第二连接器232b，第一连接器与第二连接器232b连接。主控电路板130通过第一连接器、第二连接器232b为驱动电路板232提供控制信号，从而使驱动电路板232根据驱动信号驱动显示基板210进行显示。
图12为本公开的一些实施例中提供的显示组件的示意图，如图12所示，显示组件200包括：显示基板210和设置在显示基板210上的驱动芯片250。其中，显示基板210包括：印刷电路板(Printed Circuit Board，简称PCB板)210d，还包括设置在该印刷电路板210d上的发光件210b。发光件210b位于印刷电路板210d远离箱体的一侧，发光件210b可以为微型无机发光二极管。固定部240固定在印刷电路板210d朝向箱体的一侧。在一些示例中，固定部240可以通过粘结胶、螺丝等紧固件固定在印刷电路板210d上。在另一些示例中，固定部240可以焊接在印刷电路板210d上，从而提高固定部240与印刷电路板210d的连接稳定性。
驱动芯片250固定在印刷电路板210d朝向箱体主体110的一侧，并与箱体主体110上的主控电路板130连接。其中，主控电路板130上可以设置有第一连接器(未示出)，驱动芯片250上可以设置有第三连接器251，第一连接器与第三连接器251连接，主控电路板130通过第一连接器、第三连接器251为驱动芯片250提供控制信号。驱动芯片250被配置为，根据主控电路板130提供的控制信号，控制显示基板进行显示。
当显示组件200采用图12中的结构时，可以达到足够小的厚度，这样，在不分离显示组件200与承托箱体的情况下，外部的磁性操作件300可以对调节件120产生较强的吸引力，以保证调节件120能够随磁性操作件300同步转动。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
