具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，本领域普通技术人员在没有作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。
如图1至图3所示，本实施例的灯板模组包括：支架10、灯板20、胶层30和后盖40。灯板20设置在支架10的前侧；胶层30设置在灯板20和支架10之间，灯板20通过胶层30粘接在支架10上；后盖40位于支架10的后侧且通过卡接结构50卡接在支架10上。
应用本实施例的技术方案，灯板模组包括灯板20、支架10、后盖40、胶层30和卡接结构50。胶层30设置在灯板20和支架10之间，使得灯板20和支架10黏合在一起；卡接结构 50设置在后盖40和支架10之间，使得后盖40和支架10卡接在一起。避免了在灯板20、支架10和后盖40上加工螺纹孔，简化了工序，降低了生产成本、提高了生产效率和产品质量。使用胶层30和卡接结构50实现灯板模组的无螺纹装配，能够实现灯板模组的快速装配和维修，同时有效解决了相关技术中采用螺纹连接容易损坏灯板20以及灯板20和后盖40在长期使用过程中容易变形的问题。
在本实施例中，如图2所示，灯板20所在的一侧为前侧，后盖40所在的一侧为后侧。另外需要说明的是，前侧是灯板模组面向用户的一侧，并不局限于位于空间上的前方。当灯板模组沿竖直方向放置时，灯板位于后盖的前方，当灯板模组沿水平方向放置时，灯板位于后盖的上方或者下方。
在本实施例中，胶层30为导热电子胶，具体为3M导热电子胶。胶层采用导热电子胶，导热电子胶具有良好的导热性、绝缘性以及粘性，使得灯板能够牢固地粘接在支架上，增强了灯板模组的散热性能。同时，3M导热电子胶具有良好的阻燃性，阻燃等级为V0级，提高了灯板模组在使用过程中的安全性能。
需要说明的是，在本实施例中，为了兼顾粘接的牢固性以及灯板模组的散热性能，优选3M电子胶。同时，能够将灯板牢固地粘接在支架上的其他型号的导热电子胶的使用均在本申请的保护范围内。
上述后盖40的设置能够避免灯板线路裸露在外，能够有效地保护元器件，提高产品的使用寿命。在本实施例中，考虑到成本合理问题，后盖采用塑胶材质。在其他实施方式中，后盖也可以由金属铝等具有良好的导热性能的金属制成。采用铝制后盖，可以进一步提升灯板模组的物理散热性能。
如图3和图4所示，在本实施例中，卡接结构50包括卡扣51以及与卡扣51配合的第一卡槽52。卡扣51凸出地设置在后盖40朝向支架10的一侧；第一卡槽52设置在支架10上。卡扣51凸出于后盖40的前表面，即凸出于后盖40朝向支架10一侧的表面。如图7所示，支架10包括框架11，第一卡槽52设置在框架11的顶部横梁的下表面，可以为凹槽。在安装过程中，用户将上述卡扣51伸入至框架11的顶部横梁的下方，使卡扣51卡设在第一卡槽52内，即可将后盖40固定在支架10上。安装完成后，卡扣51完全位于后盖40和支架10之间的空间内。也即卡扣51隐藏在后盖40和支架10之间的空间内。上述结构避免了卡扣51暴露在外，延长了卡扣51的使用寿命。同时，使用过程中后盖40不会因为用户不小心碰到卡扣51，使得卡扣51变形而从第一卡槽52中脱出，进而使得后盖40从支架10上脱落。
如图3、图11和图13所示，在本实施例中，卡扣51包括弹性卡臂511及设置在弹性卡臂511上的卡块512。上述卡块512的前后两侧具有斜面，在安装过程中，用户将卡扣51对准第一卡槽52的位置，支架10与卡块512前侧的斜面接触，在用户施加的朝向支架10的力的作用下，弹性卡臂511发生变形，卡扣51在弹性卡臂511的带动下朝向下移动，最终卡扣51卡设在第一卡槽52内，使后盖40固定在支架10上。
如图5和图14所示，在本实施例中，卡接结构50还包括插块53以及与插块53配合的第二卡槽54，插块53凸出地设置在后盖40朝向支架10的一侧，第二卡槽54设置在支架10上，卡扣51和插块53位于后盖40的相对的两侧。第二卡槽54设置在框架11的底部横梁的上表面，插块53向下延伸。如图3、图7和图12所示，在本实施例中，卡扣51设置在后盖40的上侧壁，插块53设置在后盖的下侧壁。用户在安装的时候，先将插块53插入到第二卡槽54内，再使卡扣51卡设在第一卡槽52内，即可实现后盖40的固定。
在本实施例中，卡扣51设置在后盖40的上侧壁，并且卡扣51的卡块512向上延伸，插块53设置在后盖40的下侧壁，并且向下延伸。在其他可行的实施方式中，卡扣可以设置在后盖的下侧壁，相应地，插块设置在后盖的上侧壁。同时，卡扣和插块也可以分别设置在后盖的左右侧壁。
如图9所示，在本实施例中，卡扣51为两个，相应的插块53也为两个。
在其他可行的实施方式中，也可以由多个卡扣以及与多个卡扣配合的多个第一卡槽实现后盖在支架上的固定。多个卡扣分别设置在后盖的上下侧壁或者设置在后盖的左右侧壁。在安装过程中，用户先将一侧的卡扣卡入第一卡槽内，再将另一侧的卡扣卡入第一卡槽内，即可实现后盖的固定。
如图7所示，支架10包括框架11和加强筋12，加强筋12包括横向加强筋121和竖向加强筋122，横向加强筋121为多个，竖向加强筋122为多个，多个横向加强筋121与多个竖向加强筋122相交设置并且均设置在框架11内部。如图7所示，在本实施例中，横向加强筋121和竖向加强筋122横纵交错形成“井字形”。多个加强筋12之间形成立体环形空间，加大了散热面积，加强了灯板模组的散热效果。上述结构的设置有利于灯板模组的立体散热，提高产品的使用寿命。
如图6所示，在本实施例中，胶层30布满支架10朝向灯板20的一侧。上述胶层30的设置，使得支架10朝向灯板20的一侧表面全都粘上胶层30，灯板20通过上述胶层30牢固地粘接在支架10上，使得灯板20不易从支架10上脱落。
在本实施例中，支架10由金属材质制成，具体为铝。铝具有密度小、抗腐蚀性能强、导热性能好等优点，使得灯板模组整体质量轻，同时具有良好的散热性能。
在本实施例未示出的其他实施方式中，支架也可以由其他导热性能良好的金属制成。
如图8至图11所示，在本实施例中，后盖40设置有通孔41，当卡扣51由于长期使用疲劳损坏或者使用过程中意外损坏，且灯板20还可以继续使用时。用户可以在上述通孔41中设置螺钉以使后盖40固定在支架10上。上述通孔41的设置考虑到了用户使用过程中可能出现的卡扣51意外损坏的情形，避免了由于卡扣51的损坏导致的整个灯板模组无法使用、或者用户继续使用没有后盖40保护以致于线路直接裸露在外的灯板模组的情况的发生。同时，给用户提供了更多的固定后盖40的方式，方便了用户的使用。
同时，后盖40设置有缺口42，缺口42与卡扣51位于后盖40的同一侧。如图8至图13所示，在本实施例中，缺口42位于弹性卡臂511的下方，在需要拆下后盖40的时候，用户可以使用工具，比如笔尖等具有一定强度的物体伸入至缺口42位置，分别卡在缺口42的侧壁以及支架10的侧壁上，向后盖40施加朝向灯板模组后侧的力，使得卡扣51沿着卡块512后侧的斜面滑出第一卡槽52，实现后盖40的拆卸。
同时，在缺口42的位置设置有三角形标识，以方便用户需要拆下后盖40的时候能够快速找到缺口42，方便了用户的使用。
根据本申请的另一个方面，提供了一种显示屏，根据本申请的显示屏的实施例(图中未示出)包括多个灯板模组，每个灯板模组为上述的灯板模组。上述灯板模组通过胶层30和卡接结构50的设置实现无螺纹装配，有效解决了相关技术中采用螺纹连接容易损坏灯板20以及灯板20和后盖40在长期使用过程中容易变形的问题。因此具有上述的灯板模组的显示屏也具有上述的优点。
同时上述胶层30和卡接结构50的设置有利于灯板模组的快速装配和维修，使元器件生产效率提高。
如图1、图2、图15和图17所示，本实施例的灯板模组包括：支架10、容置空间70、灯板20、模组电路80以及后盖40。其中，支架10包括框架11和设置在框架11内的多个横向加强筋121和多个竖向加强筋122，多个横向加强筋121与多个竖向加强筋122相交设置形成多个容置空间70，多个容置空间70包括位于支架10的中间位置的第一容置空间71、位于第一容置空间71沿横向方向的第一侧的第二容置空间72和位于第一容置空间71沿横向方向的第二侧的第三容置空间73，第一容置空间71的横截面积小于第二容置空间72的横截面积，第一容置空间71的横截面积小于第三容置空间73的横截面积；灯板20设置在支架10的前侧，灯板20包括模组电路80，模组电路80包括供电接口81、信号接口82、第一行驱动电路83、第二行驱动电路84和列驱动电路85，其中，供电接口81和信号接口82与第一容置空间71对应设置，第一行驱动电路83的主体部分和列驱动电路85的主体部分与第二容置空间72对应设置，第二行驱动电路84的主体部分与第三容置空间73对应设置；后盖40设置在支架10的后侧。
应用本实施例的技术方案，灯板模组包括：支架10、容置空间70、灯板20、模组电路80以及后盖40。灯板20设置在支架10的前侧，后盖40设置在支架10的后侧，后盖40能够有效地保护灯板20后侧的元器件，避免这些元器件裸露在外影响灯板模组的使用寿命。支架10包括框架11以及设置在框架11内部的多个横向加强筋121和多个竖向加强筋122，多个横向加强筋121和多个竖向加强筋122相交设置形成多个横截面积大小不同的容置空间70，模组电路80的不同部分分别对应不同的容置空间70设置，使得灯板模组的散热效果更好。具体地，在本实施例中，将第一行驱动电路83和列驱动电路85的主体部分设置在横截面积较大的第二容置空间72内、将第二行驱动电路84的主体部分设置在横截面积较大的第三容置空间73内，将这些发热较多的电路设置在横截面积较大的容置空间内部，使得灯板模组整 体的散热性能较好。因此，本实施例的技术方案能够有效地解决相关技术中的灯板模组散热效果较差影响使用寿命的问题。
在本实施例中，如图1和图2所示，灯板20所在的一侧为支架10的前侧，后盖40所在的一侧为支架10的后侧。框架11内部设置有两个横向加强筋121和两个竖向加强筋122，两个横向加强筋121和两个竖向加强筋122形成“井”字形结构，横向加强筋121和竖向加强筋122之间形成立体环形，加大了散热面积。
需要说明的是，上述的“第一容置空间71的横截面积”是指第一容置空间71在平行于灯板20的前表面的平面上的投影面积。对应地，第二容置空间72和第三容置空间73的横截面积也是在平行于灯板20的前表面的平面上的投影面积。电路的“主体部分”是指该电路的大部分的IC芯片，即在本实施例中：第一行驱动电路83的大部分IC芯片与第二容置空间72对应设置；列驱动电路85的大部分与第二容置空间72对应设置；第二行驱动电路84的大部分与第三容置空间73对应设置。图15中示意性地框出了第一行驱动电路83、第二行驱动电路84以及列驱动电路85的组成，当然实际电路组成并不限于图中示出的情况。
在本实施例中，“第一容置空间71沿横向方向的第一侧”为图17中的第一容置空间71的左侧，“第一容置空间71沿横向方向的第二侧”为图17中的第一容置空间71的右侧。当然，在其他可行的实施方案中，第二容置空间也可以设置在第一容置空间的右侧，对应地，第三容置空间也可以设置在第一容置空间的左侧，只要使得第二容置空间和第三容置空间分别位于第一容置空间横向上的两侧即可。
如图15所示，在本实施例中，列驱动电路85位于第一行驱动电路83远离第一容置空间71的一侧。这样可以使得灯板20内部的电路布局更加合理。
如图15所示，在本实施例中，模组电路80还包括第一信号驱动电路86和第二信号驱动电路87，第一信号驱动电路86与第二容置空间72对应设置，第二信号驱动电路87与第三容置空间73对应设置。这样可以使得灯板20内部的电路布局更加合理。
如图15所示，在本实施例中，多个容置空间70还包括位于第二容置空间72上方的第四容置空间74和位于第二容置空间72下方的第五容置空间75，第一行驱动电路83的其余部分分别设置在第四容置空间74和第五容置空间75内；多个容置空间70还包括位于第三容置空间73上方的第六容置空间76和位于第三容置空间73下方的第七容置空间77，第二行驱动电路84的其余部分分别设置在第六容置空间76和第七容置空间77内。将第一行驱动电路83和第二行驱动电路84分别设置在多个容置空间70内，这样将电路中的IC芯片打散设置，使得散热更加均匀，解决相关技术中的由于散热不均使得灯板模组容易产生高温色带的问题。
如图1、图2、图16和图9所示，后盖40朝向支架10的一侧设置有加强筋45，加强筋45包括多个横向加强筋451和多个竖向加强筋452，多个横向加强筋451和多个竖向加强筋452交错设置；灯板20的后侧设置有第一元器件布局区21和第二元器件布局区22，第一元器件布局区21内的元器件的高度大于第二元器件布局区22内的元器件的高度，第二元器件布局区22对应于后盖40上加强筋45的位置设置，第一元器件布局区21对应于后盖40的加 强筋45以外的位置。加强筋45的设置能够增强后盖40的强度，进而提升灯板模组的整体强度。第二元器件布局区22对应于加强筋45的位置设置，在第二元器件布局区22内设置高度较低的元器件，能够避免元器件与加强筋45之间产生干涉。
如图1、图2、和图18所示，在本实施例中，灯板模组还包括设置在灯板20和支架10之间的胶层30，灯板20通过胶层30粘接在支架10上；胶层30包括设置在框架11上的第一胶层31以及设置在横向加强筋121上和设置在竖向加强筋122上的第二胶层32，第二胶层32为间隔设置的多段以避让横向加强筋121和竖向加强筋122的相交位置。通过胶层30将灯板20和支架10粘接在一起，具体地，导热电子胶具有良好的导热性、绝缘性以及粘性，使得灯板20能够牢固地粘接在支架10上，实现支架10和灯板20之间的无螺丝连接。能够有效地避免采用螺丝固定连接容易损伤LED灯板。第二胶层32包括多段胶层，且多段胶层之间间隔设置，这样能够降低粘胶的精度要求同时保证粘接效果。具体地，在本实施例中，多段第二胶层32之间的间隔在40mm以下。
横向加强筋121的数量为两个，两个横向加强筋121之间的距离为第一距离A1，每个横向加强筋121与相邻的框架11之间的距离为第二距离A2，第一距离A1和第二距离A2之间的比值A1/A2满足：0.5≤A1/A2≤0.8；竖向加强筋122的数量为两个，两个竖向加强筋122之间的距离为第三距离B1，每个竖向加强筋122与相邻的框架11之间的距离为第四距离B2，第三距离B1和第四距离B2之间的比值B1/B2满足：1.8≤B1/B2≤2.4。这样设置能够在保证支架10的强度的前提下，使得灯板模组内部的电路以及电子元器件的布局更加合理。由于第一容置空间71内设置了与外界电源线和信号线插接的供电接口81和信号接口82，因此需要使得围成第一容置空间71的结构强度较大。当A1/A2＜0.5时，会使得两个横向加强筋121之间的距离过小，使得第一容置空间71内的IC芯片等元器件布局过于紧密，第一容置空间71的散热效果不好；同时会使得供电接口81和信号接口82布局过于紧密，不方便进行信号线和电源线的插拔操作。当A1/A2＞0.8时，会使得第一容置空间71四周的强度较小，也会使得第二容置空间72和第三容置空间73较小，第二容置空间72和第三容置空间73内的IC芯片等元器件布局较为紧密，散热效果不好。当B1/B2＜1.8时，会使得第四容置空间74、第五容置空间75、第六容置空间76和第七容置空间77较大，对应会设置更多的IC芯片在这些容置空间内，然而这些容置空间距离框架11较近，框架11相较于横向加强筋121和竖向加强筋122宽度更大，散热效果不好。当B1/B2＞2.4时，会使得第四容置空间74、第五容置空间75、第六容置空间76和第七容置空间77较小，能够放置的IC芯片较少，使得大部分的IC芯片均放置在灯板20的纵向的中间位置，这样布局不够合理。
具体地，在本实施例中，第一距离A1和第二距离A2之间的比值A1/A2可以为0.5、0.6或者0.8；第三距离B1和第四距离B2之间的比值B1/B2为1.8、2.1或者2.4。综合设定A1/A2的值和B1/B2的值以兼顾保证散热效果和结构强度。
如图1、图2、图15和图17所示，在本实施例中，灯板20的后侧对应于支架10的位置设置有绝缘涂层23。支架10为金属支架，具体为铝制支架。绝缘涂层23的宽度大于横向加 强筋121和竖向加强筋122的宽度，这样能够避免灯板20上的电路或者元器件触碰到金属支架，影响LED限制模组的显示效果。
在本实施例中，模组电路80中的IC芯片90与框架11、横向加强筋121和竖向加强筋122之间的距离在2mm以上。这样设置能够避免元器件触碰到金属支架影响LED限制模组的显示效果。
如图19、图20、图23和图24所示，本实施例的灯板模组包括：支架10、灯板20、后盖40以及卡接结构50。其中，灯板20设置在支架10的前侧；后盖40，设置在支架10的后侧并通过卡接结构50卡接在支架10上，卡接结构50包括与后盖40分体设置的卡扣55以及与设置于支架10的第一卡槽52，卡扣55和第一卡槽52卡接配合，卡扣55凸出地设置在后盖40的前侧。
应用本实施例的技术方案，灯板模组包括支架10、灯板20、后盖40以及卡接结构50。卡接结构50设置在支架10和后盖40之间，通过卡接结构50实现后盖40和支架10之间的安装，能够实现后盖40和支架10之间的快速装配和维修，降低了生产成本、提高了生产效率。同时，卡扣55与后盖40分体设置，便于单独进行卡扣55的加工，使得后盖40的结构简单，更加容易加工。因此，本实施例的技术方案能够有效地解决相关技术中的金属后盖上设置卡扣结构使得后盖加工困难、成本高的问题。
卡接结构50还包括设置在支架10上的第一卡槽52，将后盖40安装至支架10上之后，卡扣55完全位于后盖40和支架10之间的空间内，也即卡扣55隐藏在后盖40和支架10之间的空间内，这样能够避免卡扣55暴露在外，延长了卡扣55的使用寿命。同时，也避免了使用过程中因为用户不小心碰到卡扣55，使得卡扣55变形而从第一卡槽52中脱出，进而使得后盖40从支架10上脱落。
在本实施例中，如图19、图23和图24所示，灯板20所在的一侧为前侧，后盖40所在的一侧为后侧。另外需要说明的是，前侧是灯板模组面向用户的一侧，并不局限于位于空间上的前方。当灯板模组沿竖直方向放置时，灯板位于后盖的前方，当灯板模组沿水平方向放置时，灯板位于后盖的上方或者下方。
在本实施例中，后盖40由金属材料制成，卡扣55由塑胶材料制成。后盖40的设置能够避免灯板线路裸露在外，能够有效地保护元器件，提高产品的使用寿命。后盖40可以由金属铝等具有良好的导热性能的金属制成。采用铝制的后盖40，使得灯板模组具有较好的物理散热性能。同时，卡扣55由塑胶材料制成，塑胶材料弹性较好，同时成本低，易于生产制造。
在本实施例中，灯板20通过导热电子胶(例如3M导热电子胶)粘接在支架10上，导热电子胶具有良好的导热性、绝缘性以及粘性，使得灯板能够牢固地粘接在支架10上。
如图21、图22、图25、图26、图29和图32所示，后盖40包括后盖本体43以及设置在后盖本体43的第一边沿处的连接片44，卡扣55包括与连接片44连接的连接部551，灯板模组还包括设置在后盖本体43的第二边沿和支架10之间的插接结构，其中，第一边沿和第 二边沿相对设置。具体地，上述的第一边沿为图23中的上边沿，第二边沿为图25中的下边沿。连接片44与后盖本体43为一体成型结构，且连接片44具有结构简单的优点，使得后盖40的加工制造更加容易。卡扣55通过连接部551与连接片44连接，实现了卡扣55和后盖40之间的连接。
如图24、图29和图32所示，灯板模组还包括设置在后盖本体43的第二边沿和支架10之间的插接结构。具体地，插接结构包括插块53和第二卡槽54，其中插块53与后盖本体43为一体成型结构，第二卡槽54设置在支架10上。后盖40通过插接结构和卡接结构50安装在支架10上，具有结构简单、易于安装的优点。
如图30所示，在本实施例中，第二卡槽54和第一卡槽52均设置在支架10的前侧(即支架10朝向灯板20的一侧)，卡扣55和插块53分别位于后盖40上相对的两侧。第二卡槽54设置在支架10底部横梁的下表面上，第一卡槽52设置在支架10上部横梁的下表面上。用户在安装的时候，先将插块53插入至第二卡槽54中，再使得卡扣55卡设在第一卡槽52内即可实现后盖40的安装。
在本实施例中，卡扣55设置在后盖40的上侧壁并向上延伸，插块53设置在后盖40的下侧壁并向下延伸。在其他可行的实施方案中，卡扣也可以设置在后盖的下侧壁，相应地，插块设置在后盖的上侧壁。同时，卡扣和插块也可以分别设置在后盖的左右侧壁。
如图27至图29所示，在本实施例中，卡扣55的数量为两个，插块53的数量也为两个。
如图25至图28所示，连接片44包括与后盖本体43连接并垂直于后盖本体43的第一连接片441，连接部551包括相对设置的两个卡钩5511，第一连接片441卡设在两个卡钩5511之间。通过两个卡钩5511卡住第一连接片441即可实现连接片44和卡扣55之间的连接，结构简单且易于操作。
如图25至图28所示，连接片44还包括与第一连接片441连接并垂直于第一连接片441的第二连接片442，连接部551还包括设置于两个卡钩5511之间设置有插槽5512，部分第二连接片442插设在插槽5512内。连接片44包括相互连接的第一连接片441和第二连接片442，结构简单，易于进行生产制造。同时部分第二连接片442插设在插槽5512内，配合两个卡钩5511卡住第一连接片441能够实现卡扣55和连接片44之间的紧固连接。
需要说明的是，上述的“垂直于”是指第一连接片441与后盖本体43之间的夹角大约为90°，当然由于制造误差等，第一连接片441与后盖本体43之间的夹角可以在80°至100°之间。同样地，第一连接片441和第二连接片442之间的夹角也可以在80°至100°之间。
如图25、图26以及图33所示，在本实施例中，第二连接片442包括相互连接的第一片体4421和第二片体4422，第一片体4421与第一连接片441连接，第一片体4421的宽度大于第二片体4422的宽度，第二片体4422插设在插槽5512内。具体地，两个卡钩5511的内侧设置有导向斜面，安装时，只需要将第二片体4422对准插槽5512，第一片体4421推动导向斜 面，使得两个卡钩5511向外扩张并最终卡住第一连接片441的两端，即可实现卡扣55和连接片44之间的安装，操作简单、快捷。
如图27、图28、图30以及图31所示，卡扣55还包括与连接部551连接的弹性卡臂552以及设置在弹性卡臂552上的卡块553，卡块553卡设在第一卡槽52内。上述卡块553的前后两侧具有斜面，在安装过程中，用户将卡扣55对准第一卡槽52的位置，支架10与卡块553前侧的斜面接触，在用户施加的朝向支架10的力的作用下，弹性卡臂552发生变形，卡扣55在弹性卡臂552的带动下朝向下移动，最终卡扣55卡设在第一卡槽52内，使后盖40固定在支架10上。
如图21和图22所示，卡扣55还包括设置于连接部551的弹片554，弹片554与支架10抵接配合。将卡扣55安装至支架10上之后，弹片554能够抵住支架上侧横梁的下侧壁，能够避免后盖40晃动，保证后盖40和支架10之间的稳定性。
如图19、图20以及图23至图24所示，在本实施例中，支架10朝向后盖40的一侧设置有缓冲件60。缓冲件60设置在支架10和后盖40之间，能够避免安装过程中支架10和后盖40之间的磕碰。具体地，缓冲件60可以为EVA缓冲棉，这样在扣合后盖40的时候不会发出声响。
同时，在本实施例中，后盖40上设置有凸筋，凸筋的设置一方面能够加大后盖40的散热面积，另一方面能够增加后盖40的强度。
根据本申请的另一个方面，提供了一种显示屏，根据本申请的显示屏的实施例(图中未示出)包括灯板模组，灯板模组为上述的灯板模组。灯板模组包括支架10、灯板20、后盖40以及卡接结构50。卡接结构50设置在支架10和后盖40之间，通过卡接结构50实现后盖40和支架10之间的安装，能够实现后盖40和支架10之间的快速装配，降低了生产成本、提高了生产效率。同时，卡扣55与后盖40分体设置，便于单独进行卡扣55的加工，使得后盖40的结构简单，更加容易加工。因此，本实施例的技术方案能够有效地解决相关技术中的金属后盖上设置卡扣结构使得后盖加工困难、成本高的问题。因此具有上述的灯板模组的显示屏也具有上述的优点。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
