Abstract
一种子显示面板组件和拼接显示装置，其中子显示面板组件包括：显示基板（1）；固定框架（2），包括：底板（3）和至少一个位置调节结构（4），底板（3）与显示基板（1）相对设置，至少一个位置调节结构（4）贯穿底板（3）且与显示基板（1）相连，至少一个位置调节结构（4）配置为调整显示基板（1）与底板（3）之间的相对位置。
Description
本公开涉及显示领域，特别涉及一种子显示面板组件和拼接显示装置。
大型显示屏幕通常由多个子显示面板组件进行矩阵排列拼接构成，依靠每一子显示面板组件的播放画面进行组合形成整体的大型显示屏幕的画面。
拼接显示装置的装配过程如下：首先将显示基板与固定框架进行组装，得到子显示面板组件；然后将多个子显示面板组件拼接固定于承载箱体上。在实际应用中发现，在将多个子显示面板组件拼接固定于承载箱体的过程中，经常会出现需要对部分相邻显示基板之间的间距、以及各个显示基板所在平面的平整度进行调整。现有的调整过程如下：首先将装配好的子显示面板组件先从承载箱体上拆下，然后再将显示基板与固定框架分离，接着根据调节需求调整显示基板与固定框架之间的相对位置，再对显示基板与固定框架进行二次组装得到子显示面板组件，最后将完成调整的子显示面板组件固定于承载箱体上。
在上述调整过程中，需要对显示基板与固定框架进行拆卸和再组装，这会导致拼接显示装置的装配效率低，而且会增加显示基板损坏的概率。

为使本领域技术人员更好地理解本公开的技术方案，下面结合附图和具体实施方式对本公开作进一步详细描述。
以下将参照附图更详细地描述本公开。在各个附图中，相同的元件采用类似的附图标记来表示。为了清楚起见，附图中的各个部分并没有都按比例绘制。此外，在图中可能未示出某些公知的部分。
在下文中描述了本公开的许多特定的细节，例如部件的结构、材料、尺寸、处理工艺和技术，以便更清楚地理解本公开。但正如本领域的技术人员能够理解的那样，可以不按照这些特定的细节来实现本公开。
图1为本公开实施例提供的一种子显示面板组件的一种结构示意图。图2为本公开实施例中固定框架与显示基板进行组装前的一种结构示意图。图3为固定框架与显示基板进行组装前的局部背面示意图。图4为本公开实施例中位置调节结构的一种结构示意图。图5为本公开实施例中利用第一微调结构控制显示基板在第一方向上移动的一种示意图。如图1至图5所示，该子显示面板组件包括：显示基板1和固定框架2。其中，固定框架2包括：底板3和至少一个位置调节结构4，底板3与显示基板1相对设置，位置调节结构4贯穿底板3且与显示基板1相连，位置调节结构4配置为调整显示基板1与底板3之间的相对位置。
在本公开实施例中，在显示基板1与固定框架2完成组装后，可通过固定框架2上的位置调节结构4可以调整显示基板1与固定框架2之间的相对位置，整个调节过程无需对完成组装的显示基板1和固定框架2进行拆卸和二次组装，可有效提升拼接显示装置的装配效率，降低显示基板1损坏的概率。
在一些实施例中，显示基板1包括：承载基板101、多个发光元件102和至少一个第一连接件9；发光元件102固定于承载基板101远离底板3的一侧，第一连接件9固定于承载基板101靠近底板3的一侧；位置调节结构4与第一连接件9一一对应，位置调节结构4与对应的第一连接件9相连。
在本公开实施例中，承载基板101可以为FR4(美国电气制造商协会(NEMA)规定的一种可燃性等级)类型的印刷电路板，由绝缘板、连接导线层和用于装配焊接电子元件(例如发光元件、驱动元件、传感元件等)的焊盘组成，绝缘板和连接导线层可以有多层，位于不同层连接导线可以通过在绝缘板上打孔以实
现过孔连接。可以理解的是，承载基板101的材质也可以为玻璃、塑料、石英、金属等材质，承载基板上设置有线路和用于装配焊接电子元件(例如发光元件，mini LED或micro LED)的焊盘。
发光元件102可以为微型发光二极管(Micro LED)或迷你发光二极管(Mini LED),可通过固晶工艺将Micro LED或Mini LED安装于承载基板101的第一侧(一般称为正面侧)；在承载基板101的第二侧(一般称为背面侧)设置有电路板，用于向第一侧的发光元件提供电信号。
在本公开实施例中，第一连接件9固定于承载基板101的背面侧。在一些实施例中，第一连接件9可以采用不锈钢材质，在承载基板101的第二侧预留用于供第一连接件9进行焊接的焊盘。
继续参见图4和图5所示，在一些实施例中，位置调节结构4包括：第一微调结构4a，第一微调结构4a与对应的第一连接件9相连，第一微调结构4a用于调整显示基板1相对于底板3在第一方向Z上的位置，第一方向Z与承载基板101的法线平行。也就是说，通过第一微调结构4a可控制显示基板1在第一方向Z上进行移动。
在一些实施例中，底板3上形成有与第一微调结构4a一一对应的至少一个第一通孔301；第一微调结构4a包括：调节件7和第二连接件8。
其中，调节件7具有沿第一方向Z延伸的中空通道701，调节件7的至少一部分位于第一通孔301内，调节件7的外侧壁与对应的第一通孔301的内侧壁活动相连，调节件7件配置为能够相对于第一通孔301在第一方向Z上进行移动；
第二连接件8贯穿中空通道701，第二连接件8靠近第一连接件9的一端与第一连接件9相连，第二连接件8远离第一连接件9的一端与调节件7远离第一连接件9的一端抵接，第一连接件9与调节件7靠近第一连接件9的一端抵接。
在本公开实施例中，第二连接件8贯穿调节件7的中空通道701并与对应的第一连接件9相连，同时第一连接件9靠近调节件7的一端和第二连接件8
远离所述第一连接件9的一端分别与调节件7的两端抵接，即第二连接件8与第一连接件9二者相固定的同时，二者还在第一方向Z上夹持固定调节件7。当通过调整调节件7相对于第一通孔在第一方向Z上进行移动的过程中，会同步带动第一连接件9以及与第一连接件9固定连接的显示基板1相对于底板3在第一方向Z进行同步移动，以实现对显示基板1相对于底板3在第一方向Z上的位置进行调节。
在一些实施例中，第一通孔301为第一螺纹孔；调节件7包括：中空螺钉，中空螺钉的外螺纹与对应的第一螺纹孔的内螺纹适配，中空螺钉通过在第一螺纹孔中转动能够在第一方向Z上移动。也就是说，通过旋转中空螺钉可使得中空螺钉在第一方向Z上进行移动，以带动显示基板1在第一方向Z上进行同步移动。
在一些实施例中，第一连接件9包括：连接柱，连接柱的靠近承载基板101的一端与承载基板101固定，连接柱的远离承载基板101的一端形成有第二螺纹孔。
第二连接件8包括：第一螺钉，第一螺钉的外螺纹与对应的第二螺纹孔的内螺纹适配；第一螺钉的盘头在平行于底板3所处平面的截面的面积，大于中空通道701在平行于底板3所处平面的截面的面积，第一螺钉的盘头与调节件7远离连接柱的一端抵接；第一螺钉的螺杆在平行于底板3所处平面的截面的面积，小于中空通道701在平行于底板3所处平面的截面的面积，第一螺钉的螺杆贯穿中空通道701，且第一螺钉的螺杆远离第一螺钉的一端与对应的连接柱通过螺纹连接。通过旋转第一螺钉的盘头，可使得第一螺钉在第一方向Z上进行运动。
需要说明的是，上述第二连接件8采用螺钉、第一连接件9中开设螺纹孔，第一连接件9和第二连接件8采用螺纹固定的方式，其仅为本公开中的一种可选实施方案，其不会对本公开的技术方案产生限制。在实际应用中，还可以采用其他方式将第一连接件9和第二连接件8进行固定，例如二者直接卡合固定等。
需要说明的是，在本公开实施例中，可在底板3上设置多个位置调节结构4，该多个位置调节结构4分布于不同位置，通过位于不同位置的位置调节结构4内第一微调结构4a的调整，可对单个显示基板1上不同区域相对于底板3的距离进行调整，从而能够对单个显示基板1的平整度进行调节。在相关技术中，子显示面板组件内单个显示基板1的平整度一般大于0.1mm；而在本申请中，通过第一微调结构4a的调节，可使得单个显示基板1的平整度小于0.05mm。可以理解的是，单个显示基板1的平整度小于0.05mm，表示该承载基板101的法线方向基本垂直于底板3所在平面，例如，承载基板101的法线方向与底板3所在平面之间的夹角在87°到93°之间。
图6为本公开实施例中位置调节结构的另一种结构示意图。图7为本公开实施例中利用第二微调结构控制显示基板在平行于承载基板所处平面的方向上移动的一种示意图。如图6和图7所示，图6所示位置调节结构4不但包括前面实施例中的第一微调结构4a，还包括第二微调结构4b。下面仅对第二微调结构4b进行详细描述。
其中，第二微调结构4b与对应的第二连接件8相连，第二微调结构4b用于调节第二连接件8沿对应的第二方向P进行移动，以调整显示基板1相对于底板3在第二方向P上的位置；第二方向P与承载基板101所处平面平行。其中，在利用第二微调结构4b调节第二连接件8以在对应的第二方向P上进行移动时，可以带动与第二连接件8固定的第一连接件9、与第一连接件9固定的显示基板1在第二方向P上进行同步移动；也就是说，通过第二微调结构4b可控制显示基板1在第二方向P上进行移动。
每个第二微调结构4b对应一个与承载基板101所处平面相平行的第二方向P，不同第二微调结构4b所对应的第二方向P可以相同也可以不同，后面将结合具体示例作详细描述。
在一些实施例中，在调节件7的侧壁的位于底板3远离显示基板1一侧的部分形成有第二通孔702；第二微调结构4b贯穿对应的第二通孔702与第二连接件8位于中空通道701内的部分相连。
进一步可选地，第二连接件8位于中空通道701内的部分形成有沿对应的第二方向P与第二通孔702相对设置的第三螺纹孔803；第二微调结构4b包括：第二螺钉，第二螺钉的外螺纹与对应的第三螺纹孔803的内螺纹适配；第二螺钉的盘头位于调节件7的侧壁的外侧；第二螺钉的螺杆在垂直于对应的第二方向P的截面的面积，小于第二通孔702在垂直于对应的第二方向P的截面的面积，第二螺钉的螺杆贯穿第二通孔702且与第三螺纹孔803通过螺纹连接，第二螺钉通过在第三螺纹孔803中转动能够驱动第二连接件8在第二方向P上移动。也就是说，通过旋转第二螺钉可使得与第二螺钉螺纹连接的第二连接件8(具体可以为前文中的第一螺孔)在对应的第二方向P上进行移动，在第二连接件8在第二方向P上进行移动时，可以带动与第二连接件8固定的第一连接件9、与第一连接件9固定的显示基板1在第二方向P上进行同步移动。在一些实施例中，第二通孔702不具有内螺纹，第二螺钉不与第二通孔702螺纹连接。
在一些实施例中，可以不设置第三螺纹孔803或者将第三螺纹孔803设置为盲孔，而将第二通孔702设置为螺纹孔，第二螺钉与第二通孔702螺纹连接。在这种情况下，旋转第二螺钉使得第二螺钉相对于第二通孔702在第二方向P上移动，进而推动第二连接件8在第二方向P上移动。在第二连接件8在第二方向P上移动时，可以带动与第二连接件8固定的第一连接件9、与第一连接件9固定的显示基板1在第二方向P上同步移动。
在一些实施例中，第二微调结构4b的数量为多个；存在至少两个第二微调结构4b所对应的第二方向P为不同方向。
在一些实施例中，底板3具有第一侧边、第二侧边、第三侧边和第四侧边；第一侧边和第二侧边在第三方向上相对设置，第一侧边和第二侧边分别沿第四方向延伸，第三侧边和第四侧边在第四方向上相对设置，第三侧边和第四侧边分别沿第三方向延伸；第三方向、第四方向均与承载基板101所处平面平行，且第三方向与第四方向相交。
最靠近于第一侧边的一个或多个第二微调结构4b所对应的第二方向为第三方向；和/或，最靠近于第二侧边的一个或多个第二微调结构4b所对应的第二
方向为第三方向；和/或，最靠近于第三侧边的一个或多个第二微调结构4b所对应的第二方向为第四方向；和/或，最靠近于第四侧边的一个或多个第二微调结构4b所对应的第二方向为第四方向。在一些实施例中，最靠近于第一侧边的一个或多个第二微调结构4b与最靠近于第二侧边的一个或多个第二微调结构4b相互配合，调节显示基板1在第三方向上移动。在一些实施例中，最靠近于第三侧边的一个或多个第二微调结构4b与最靠近于第四侧边的一个或多个第二微调结构4b配合，调节显示基板1在第四方向上移动。
图8为本公开实施例中多个位置调节结构的一种分布示意图。如图8所示，作为一个可选示例，底板3上设置有4个位置调节结构4，分别位于靠近第一侧边301的中点的位置、靠近第二侧边302的中点的位置、靠近第三侧边303的中点的位置和靠近第四侧边304的中点的位置。
其中，靠近第一侧边301的中点的位置调节结构401内第二微调结构4b所对应的第二方向P1为第三方向X(图8中的水平方向)，靠近第二侧边302的中点的位置调节结构402内第二微调结构4b所对应的第二方向P1为第三方向X(图8中的水平方向)，靠近第三侧边303的中点的位置调节结构403内第二微调结构4b所对应的第二方向P2为第四方向Y(图8中的竖直方向)，靠近第四侧边304的中点的位置调节结构404内第二微调结构4b所对应的第二方向P2为第四方向Y(图8中的竖直方向)。
即，通过靠近第一侧边301的中点的位置调节结构401内第二微调结构4b和靠近第二侧边302的中点的位置调节结构402内第二微调结构4b中至少一者，可控制显示基板1朝向第三方向X上的至少一侧进行移动；通过靠近第三侧边303的中点的位置调节结构403内第二微调结构4b和靠近第四侧边304的中点的位置调节结构404内第二微调结构4b中至少一者，可控制显示基板1朝向第四方向Y上的至少一侧进行移动。
通过上述设置，可对显示基板1相对于底板3在第三方向X和第四方向Y的相对位置进行控制。当然，本公开实施例中，位置调节结构内第二微调结构所对应的第二方向也可以不为上述第三方向X和第四方向Y，而是与第三方向X
和第四方向Y均相交的一个方向，具体情况可根据实际需要来进行调整。
图9为本公开实施例中多个位置调节结构的另一种分布示意图。如图9所示，在一些实施例中，底板3上设置有呈3行、4列阵列排布的12个位置调节结构。其中，
最靠近于第一侧边301的一个位置调节结构401内第二微调结构4b所对应的第二方向P1为第三方向X，最靠近于第二侧边302的一个位置调节结构402内第二微调结构4b所对应的第二方向P1为第三方向X，最靠近于第三侧边303的四个位置调节结构403内第二微调结构4b所对应的第二方向P2为第四方向Y，最靠近于第四侧边304的四个位置调节结构404内第二微调结构4b所对应的第二方向P2为第四方向Y。
位于中间部分的两个位置调节结构405内可以仅包括第一微调结构4a而不包括第二微调结构4b；或者，位于中间部分的两个位置调节结构405内可以包括第二微调结构4b，该两个位置调节结构405内第二微调结构4b所对应的第二方向P3(例如，图9中所示第二方向P3与第三方向X和第四方向Y均相交)可以根据实际需要来进行预先设定。
需要说明的是，在本公开实施例中，对于位置调节结构的数量、排布均不作限定。
在本公开实施例中，通过位置调节结构内的第一微调结构，可对显示基板在平行于底板的法线方向的位置进行调节，可实现单个显示基板的平整度小于0.05mm，且相邻显示基板的之间的平整度小于0.05mm；通过位置调节结构内的第二微调结构，可实现相邻显示基板的之间的间距小于或等于0.05mm。
在相关技术中，为实现子显示面板组件与承载箱体的对位，一般会在子显示面板组件上设置铝制定位销，且在承载箱体上设置对应的定位孔，通过铝制定位销与定位孔的配合以实现子显示面板组件与承载箱体的对位。相关技术中的铝制定位销一般是与铝制底板一体成型，二者不可分离。
然而，在实际应用中发现，随着拼接尺寸越来越大，由于结构件的制作存在公差，拼接尺寸越大，公差积累越多，可能大屏拼接组装到某一尺寸时，就
会出现子显示面板组件与承载箱体组装不到一起的问题。研究发现，这是由于公差积累过大而导致子显示面板组件中的铝制定位销无法安装于承载箱体上对应的定位孔内，进而导致子显示面板组件与承载箱体无法组装。
为有效解决上述技术问题，本公开提供了相应的解决方案。图10为本公开实施例中定位销的一种结构示意图。如图10所示，在一些实施例中，子显示面板组件还包括：至少一个定位销6，位于底板3远离显示基板1的一侧且与底板3可拆卸连接，定位销6配置为与承载箱体上的定位孔配合，以对位并组装子显示面板组件和承载箱体。
在本公开实施例中，由于定位销6与底板3采用可拆卸连接的方式进行固定，故在出现由于公差积累过大而导致子显示面板组件中的定位销6无法安装于承载箱体上对应的定位孔内时，仅需将该定位销6从底板3上拆卸下来，以保证可以继续组装拼接。
在一些实施例中，定位销6包括：定位销主体601和与定位销主体601相连的螺杆602；底板3上形成有与定位销一一对应的至少一个第四螺纹孔，第四螺纹孔的内螺纹与对应的定位销6的螺杆602的外螺纹适配。也就是说，当不需要定位销时，仅需通过旋转定位销主体，以使得定位销6中的螺杆602与第四螺纹孔进行分离。
在一些实施例中，定位销主体601的材料包括塑料。在本公开实施例中，当沿某一方向拼接的子显示面板组件的数目达到一定数量后，拼接公差将以加和的方式累积，而塑料质软、摩擦阻力小，仍可将子显示面板组件与承载箱体对位组装，若某个子显示面板组件无法与承载箱体对位组装，可将该子显示面板组件上的定位销6从底板3上拆卸下来，从而继续进行组装拼接。
需要说明的是，在本公开实施例中，底板上所设置的定位销的数量可以为1个或多个。本公开的技术方案对于定位销的数量和排布均不作限定。
基于同一构思，本公开实施例还提供了一种拼接显示装置。图11为本公开实施例提供的一种拼接显示装置的结构示意图。如图11所示，该拼接显示装置包括：多个子显示面板组件11，其中至少一个子显示面板组件11采用前面实施
例所提供的子显示面板组件。对于子显示面板组件11的具体描述，可参见前面实施例中的内容，此处不再赘述。
在一些实施例中，该拼接显示装置还包括：承载箱体12；承载箱体12配置为承载多个子显示面板组件11。
应当说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括要素的过程、方法、物品或者设备中还存在另外的相同要素。
依照本公开的实施例如上文所述，这些实施例并没有详尽叙述所有的细节，也不限制该公开仅为所述的具体实施例。显然，根据以上描述，可作很多的修改和变化。本说明书选取并具体描述这些实施例，是为了更好地解释本公开的原理和实际应用，从而使所属技术领域技术人员能很好地利用本公开以及在本公开基础上的修改使用。本公开仅受权利要求书及其全部范围和等效物的限制。
