在一些可选的实施方式中，第二防锈导电件在显示模块上的投影覆盖第一防锈导电件以及磁性吸附件。
在一些可选的实施方式中，磁性吸附件与第二防锈导电件在沿显示模块的垂向间隔设置。
在一些可选的实施方式中，连接组件还包括隔离电容，隔离电容的一端与电路板的接地电路连接，隔离电容的另一端与箱体连接。
在一些可选的实施方式中，隔离电容被构造为表面贴装器件。
在一些可选的实施方式中，第一防锈导电件和磁性吸附件被构造为表面贴装器件。
在一些可选的实施方式中，连接组件的个数为多个，多个连接组件沿显示模块的周向间隔设置。
与相关技术相比，本申请实施例提供的显示屏具有如下优点：
显示屏包括显示模块、箱体以及连接组件；连接组件包括第一防锈导电件、第二防锈导电件以及磁性吸附件。
其中，第一防锈导电件和第二防锈导电件为导电件且具有防生锈的效果。第一防锈导电件设置在显示模块上，且与显示模块上电路板的接地电路相连，第二防锈导电件与箱体相连，第一防锈导电件和第二防锈导电件相接触，可以使得电路板的接地电路与箱体实现导通。这样，箱体可以形成一个较为完整的屏蔽结构，避免显示屏的辐射溢出并对外部设备产生电磁干扰，同时也能避免显示屏受到电磁干扰。且由于第一防锈导电件和第二防锈导电件均具有防生锈的效果，第一防锈导电件和第二防锈导电件在较长长时间范围内均可以稳定的导通，屏蔽效果较好。
连接组件还包括磁性吸附件，磁性吸附件与显示模块相连，磁性吸附件和第二防锈导电件之间具有磁性力。这样，可以通过磁性吸附件和第二防锈导电件之间的磁性力使得显示模块和箱体吸附固定，相对于相关技术中，显示模块和箱体通过螺纹紧固件相连的方式，本实施例中显示屏易于组装。
除了上面所描述的本申请实施例解决的技术问题、构成技术方案的技术特征以及由这 些技术方案的技术特征所带来的有益效果外，本申请实施例提供的显示屏所能解决的其他技术问题、技术方案中包含的其他技术特征以及这些技术特征带来的有益效果，将在具体实施方式中作出详细的说明。

具体实施方式
为了使本申请实施例的上述目的、特征和优点能够更加明显易懂，下面将结合本申请实施例中的附图，对本申请实施例中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申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其它实施例，均属于本申请保护的范围。
相关技术中，显示屏的箱体通常为镁铝合金，然而，镁铝合金易与空气发生氧化反应，导致电路板与箱体之间不能有效导通，显示屏的屏蔽效果变差。且为避免箱体与电路板的连接位置处通常不能生锈，相关技术中，箱体通常采用不易生锈的材质或者在箱体以及电 路板的导通位置处设置电镀金属层或者喷涂导电漆，成本较高。
有鉴于此，本申请实施例包括连接显示模块和箱体的连接组件，连接组件包括不易生锈的第一防锈导电件和第二防锈导电件，第一防锈导电件与电路板的接地电路导通，第二防锈导电件与箱体导通。这样，第一防锈导电件和第二防锈导电件接触后，就可以实现在较长时间范围内稳定的导通，显示屏可以具有稳定的屏蔽效果。且连接组件还包括磁性吸附件，通过磁性吸附件和第二防锈导电件之间的磁性力固定显示模块和箱体，易于组装。
图1为本申请实施例提供的显示屏中显示屏模块的结构示意图。图2为图1中连接组件的结构示意图。图3为图2中第一防锈导电件的结构示意图一。图4为图2中第一防锈导电件的结构示意图一。图5为图2中第二防锈导电件的磁感线分布示意图。
请参阅图1至图5，本申请实施例提供一种显示屏，其包括多个显示屏模块，多个显示屏模块并列设置；每个显示屏模块均包括显示模块10、箱体20以及连接组件，连接组件连接显示模块10和箱体20，显示模块10上设有电路板；连接组件包括第一防锈导电件31、第二防锈导电件32以及磁性吸附件33，第一防锈导电件31和磁性吸附件33均设置在显示模块10上，且第一防锈导电件31与电路板的接地电路相连，第二防锈导电件32设置在箱体20上；其中，第一防锈导电件31和第二防锈导电件32相抵接，以使电路板的接地电路与箱体20连接；磁性吸附件33和第二防锈导电件32处于磁性力作用范围内，磁性吸附件33以及第二防锈导电件32之间通过磁性力相互吸附时，显示模块10与箱体20相互固定。
在一实施例中，显示屏用于根据需要显示预设文字、图像、视频等信息，显示屏可以为LED(light-emitting diode)显示屏，本实施例不进行限制。其中，显示屏包括多个并列设置的显示屏模块，每个显示屏模块用于显示部分文字、图像或视频信息，多个显示屏模块显示的信息组合成为预设的显示信息。
每个显示屏模块均包括显示模块10、箱体20、供电模块40、控制模块50以及连接显示模块10和箱体20的连接组件。
显示模块10上设有电路板11，电路板11的一端与显示模块10相连，电路板11的另一端与显示屏模块的控制模块50相连，以实现显示模块10与控制模块50之间的通信，并根据控制模块50显示预设的文字、图像、视频等信息。供电模块40分别与控制模块50、显示模块10以及电路板11连接，用于提供电能。
箱体20可以为容器状结构，显示模块10固定并封盖箱体20的开口。这样，显示模块10以及箱体20围成的空腔内可以用于容置连接组件、供电模块40以及控制 模块50等，以简化显示屏的外观。箱体20的材质可以为金属，强度高，使用寿命较长。
连接组件包括第一防锈导电件31和第二防锈导电件32，第一防锈导电件31与电路板11的接地电路导通，第二防锈导电件32与箱体20相连并导通。其中，“防锈导电件”指的是这样的部件，其既具有导电的能力，也具有防止生锈的能力。
那么，第一防锈导电件31和第二防锈导电件32均为可导电材质件，且具有防锈蚀的功能。这样，显示模块10与箱体20组装完成后，第一防锈导电件31和第二防锈导电件32相抵接并导通，且由于第一防锈导电件31和第二防锈导电件32均具有防生锈的功能，第一防锈导电件31和第二防锈导电件32可以在较长时间范围内维持稳定导通的状态，使得显示屏具有稳定的屏蔽效果。
这样，可以不必在第一防锈导电件31和第二防锈导电件32的导通位置处镀防锈金属层，同时，箱体20也可以根据需要选择任意材质，例如箱体20的材质可以为铁等，降低了显示屏的制作成本。
第二防锈导电件32可以通过螺纹紧固件与箱体20固定连接，连接稳定性较高，且可以与箱体20有效导通。
连接组件还包括磁性吸附件33，显示模块10组装在箱体20上后，磁性吸附件33与第二防锈导电件32处于磁性力作用范围内，磁性吸附件33与第二防锈导电件32之间具有磁性力。这样，显示模块10与箱体20组装后，即可以通过该磁性力相对固定，相对于相关技术中显示模块10与箱体20通过螺栓等紧固件相对固定的方式，本实施例通过磁性力吸附固定的方式结构简单，组装效率较高。
那么，第二防锈导电件32与磁性吸附件33中的至少一者为磁性件，例如磁铁。示例性的，第二防锈导电件32和磁性吸附件33均为磁性件，或者，磁性吸附件33为磁铁，第二防锈导电件32为能够与磁铁吸合的金属构件。
考虑到第一防锈导电件31和第二防锈导电件32均需要具有防锈效果，本实施例中，第二防锈导电件32为磁性件，此时，磁性吸附件33可以为金属构件或者磁性件，本实施例不进行限制。
可以理解的，磁铁表面具有电镀层，例如镀锌、镀镍等，因此，磁铁具有良好的防锈性能。且为了使得第二防锈导电件32具有良好的导电性能，磁铁可以为钕铁硼材质件、钐钴材质件、铝镍钴材质件或铁铬钴材质件。
其中，第二防锈导电件32可以通过螺纹紧固件与箱体20固定连接。可选的，箱 体20上可以设置凸出的支撑部21，支撑部21可以与箱体20一体成型或者支撑部21可以为与箱体20固定相连的金属件。支撑部21朝向显示模块10一侧伸出，第二防锈导电件32通过螺纹紧固件与支撑部21的端部相连。这样，可以减小第二防锈导电件32的尺寸，降低制作成本。
那么，为实现第一防锈导电件31和第二防锈导电件32的导通，第一防锈导电件31也可以为磁性件，例如钕铁硼材质件、钐钴材质件、铝镍钴材质件或铁铬钴材质件。
可以理解的，第一防锈导电件31也可以为金属件。示例性的，第一防锈导电件31的材质可以为金、铜、铂、铬、钛、银、不锈钢等。第一防锈导电件31的表面也可以设置镀层，例如铜表面镀金，以提高第一防锈导电件31的防锈性能，使第一防锈导电件31和第二防锈导电件32能够在较长时间范围内稳定的导通。
其中，第一防锈导电件31和第二防锈导电件32相接触，即可实现第一防锈导电件31和第二防锈导电件32的导通。为避免第一防锈导电件31和第二防锈导电件32分离，第一防锈导电件31为具有弹性的金属件，第一防锈导电件31的一端与电路板11相连，第一防锈导电件31的另一端通过自身弹性力与第二防锈导电件32相抵接。
在一实施例中，第一防锈导电件31的一端与电路板11连接，第一防锈导电件31的另一端为自由端并朝向第二防锈导电件32伸出。且电路板11与第二防锈导电件32沿显示模块10垂向的间距小于第一防锈导电件31处于自由状态下的沿显示模块10垂向的尺寸。这样，显示屏模块组装完成后，第一防锈导电件31可以受压变形并挤压在电路板11与第二防锈导电件32之间，即使得第一防锈导电件31和第二防锈导电件32可以维持相互抵接的状态，第一防锈导电件31和第二防锈导电件32可以有效导通。
其中，第一防锈导电件31可以为条弧形结构件。在一些可选的实施方式中，第一防锈导电件31包括固定部311、抵顶部312和连接固定部311与抵顶部312的弯折部313，固定部311用于与电路板11相连，抵顶部312在弯折部313的弹性力作用下与第二防锈导电件32相抵接。
这样，第一防锈导电件31可以构成类似U型的结构件，固定部311和抵顶部312相对设置，固定部311用于与显示模板的电路板11固定连接，抵顶部312位于靠近第二防锈导电件32的一侧，弯折部313用于提供弹性力，使得固定部311和抵顶部312具有向外扩张的趋势。即抵顶部312的端部会在弹性力的作用下朝向第二防锈导电件32一侧伸出并与第二防锈导电件32抵接，由此，第一防锈导电件31和第二防 锈导电件32维持稳定接触的状态。
考虑到抵顶部312与第二防锈导电件32之间无锁止结构，为避免因显示屏晃动，抵顶部312相对第二防锈导电件32移动，导致抵顶部312与第二防锈导电件32相互分离，在一些可选的实施方式中，第一防锈导电件31还包括止挡部314，止挡部314分别与固定部311的两侧固定相连并朝向第二防锈导电件32的一侧延伸；部分抵顶部312在沿显示模块的垂向Y上伸入止挡部314之间。
可以理解的，显示模块10为板状结构件，显示模块的垂向Y即与板状的显示模块10垂直设置。
其中，为避免止挡部314与第二防锈导电件32发生干涉，抵顶部312的自由端朝向远离固定部311的一侧伸出止挡部314。这样，当抵顶部312与第二防锈导电件32抵接时，止挡部314与第二防锈导电件32在沿显示模块的垂向Y上仍具有间隙。
当第二防锈导电件32为磁性件时，可以理解的，第二防锈导电件32通常为圆柱状结构，圆柱状结构的两端为南北极，且圆柱状的第二防锈导电件32具有轴线。相应的，第二防锈导电件的垂向X与第二防锈导电件32的轴线垂直设置。
第二防锈导电件32的轴线与显示模块的垂向Y可以呈任意夹角设置。可选的，为易于组装，本实施例中，第二防锈导电件32的轴线与显示模块的垂向Y平行设置，即第二防锈导电件的垂向X与显示模块10垂直设置。
请参阅图5，圆柱状磁性件的端面中心位置处的磁感线分布较少，磁场强度较弱，而圆柱状磁性件端面边缘位置处的磁感线分布较多，磁场强度较强。
相应的，磁性吸附件33和第二防锈导电件32在第二防锈导电件的垂向X上错开设置。
其中，磁性吸附件33和第二防锈导电件32均具有轴线，且磁性吸附件33和第二防锈导电件32的轴线均与显示模块10垂直设置，即磁性吸附件33的轴线和第二防锈导电件32的轴线平行设置。本实施例中，磁性吸附件33和第二防锈导电件32在第二防锈导电件的垂向X上错开设置指的是，磁性吸附件33的轴线和第二防锈导电件32的轴线具有预设间距，以使磁性吸附件33位于第二防锈导电件32端面的边缘位置处。
这样，磁性吸附件33和第二防锈导电件32之间的磁性力较大，显示模块10通过该磁性力固定在箱体20上后，显示模块10与箱体20之间的连接稳定性较高。
当然，磁性吸附件33的轴线和第二防锈导电件32的轴线的间距需要处于预设范 围内，以避免因距离较大，导致磁性吸附件33与第二防锈导电件32之间的磁性力较小。示例性的，当磁性吸附件33和第二防锈导电件32为等直径的圆柱状结构时，磁性吸附件33的轴线可与第二防锈导电件32的边缘对齐。或者，请参阅图2，磁性吸附件33在第二防锈导电件的垂向X上的截面尺寸可以小于第二防锈导电件32的截面尺寸，磁性吸附件33相对于第二防锈导电件32偏心设置。此时，第二防锈导电件32在显示模块10上的投影可以覆盖磁性吸附件33的投影。
可以理解的，由于磁性吸附件33和第二防锈导电件32在第二防锈导电件的垂向X上错开设置，显示模块10上与第二防锈导电件32相对应的位置处相应的形成避让区域，该避让区域与磁性吸附件33相邻设置。
可选的，考虑到第一防锈导电件31的尺寸较小，本实施例可将第一防锈导电件31放置在该避让区域内，这样，至少部分第一防锈导电件31与第二防锈导电件32相对设置。
当第一防锈导电件31的截面尺寸小于等于避让区域的截面尺寸时，第二防锈导电件32在显示模块10上的投影覆盖第一防锈导电件31以及磁性吸附件33。这样，显示屏模块的结构较为紧凑，避免连接组件占用过多的显示屏模块内部空间。
其中，磁性吸附件33与第二防锈导电件32可通过磁性力贴合设置。在一些可选的实施方式中，磁性吸附件33与第二防锈导电件32在沿显示模块的垂向Y间隔设置。即磁性吸附件33和第二防锈导电件32在显示模块的垂向Y上具有预设间隙，这样，显示屏组装过程中，磁性吸附件33和第二防锈导电件32之间的装配精度降低，易于组装。
其中，第一防锈导电件31、第二防锈导电件32以及磁性吸附件33的截面尺寸可以根据需要进行设置。示例性的，第二防锈导电件32的直径可以为20mm，磁性吸附件33的直径为10mm，第二防锈导电件32与磁性吸附件33在显示模块10垂向上的间距可以为0.5mm，磁性吸附件33与第二防锈导电件32在磁性吸附件33垂向上的错开距离为1mm-2mm。
这里需要说明的是，本申请实施例涉及的数值和数值范围为近似值，受制造工艺的影响，可能会存在一定范围的误差，这部分误差本领域技术人员可以认为忽略不计。
可以理解的，显示屏为低压器件，为避免瞬态过电压对显示屏造成冲击，例如，雷电或强静电加载在显示屏上时，显示屏内会瞬间生成大电流，导致显示屏的灯珠、电路板11等器件损坏。
在一些可选的实施方式中，连接组件还包括隔离电容34，隔离电容34的一端与电路板11的接地电路连接，隔离电容34的另一端与箱体20连接。这样，隔离电容34可以吸收瞬间大电流，以避免瞬间大电流流经电容屏，也就对电容屏形成防护。可以理解的，电路板11上可以同时设置与隔离电容34相连的保护电路，本实施例不进行限制。
其中，隔离电容34参数可根据需要进行选择，示例性的，隔离电容34的耐压值可以为2KV，隔离电容34的电容值为100pF。
在一些可选的实施方式中，隔离电容34被构造为表面贴装器件(Surface Mounted Devices，SMD)，第一防锈导电件31和磁性吸附件33也可以被构造为表面贴装器件(SMD)。示例性的，隔离电容34、第一防锈导电件31和磁性吸附件33均通过编带包装的方式进行封装。这样，隔离电容34、第一防锈导电件31以及磁性吸附件33均可以通过本领域技术人员熟知的贴片机组装在电路板11上，然后再通过焊接工艺固定在电路板11上，便于批量生产，提高组装效率。
其中，磁性吸附件33与第一防锈导电件31之间的间距可以为0.5mm，以便于贴片机贴片组装。本实施例不对隔离电容34与磁性吸附件33或隔离电容34与第一防锈导电件31之间的距离不进行限制，只要便于贴片机贴片组装即可。
在一些可选的实施方式中，连接组件的个数为多个，多个连接组件沿显示模块10的周向间隔设置。这样，沿显示模块10所在的平面，多个连接组件间隔设置，可以使得显示模块10具有较高的平整度，多个显示屏模块的不同显示模块10之间也具有较高的平整度。
示例性地，连接组件的个数可以为四个，并分别设置在显示模块10的四个角部位置处，即能使得显示模块10具有较好的平整度，又能降低显示屏的成本。
本说明书中各实施例或实施方式采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分相互参见即可。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合实施方式或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
