 本发明的实施方式
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，所描述的实施例仅仅是本申请一部分实施例，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，都属于本申请保护的范围。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
现有技术中，LED显示屏、LED箱体均有多个LED单元板相互拼接形成，一般LED单元板均采用矩形设置，并且，为了方便安装，一般都在处于LED单元板显示面边缘的安装部预留一定的拼接空间，如此，拼接形成的LED显示屏或LED箱体在显示视频图像时，拼接连接线非常明显，容易影响显示效果。
因此，为了解决上述问题，本申请提出了一种显示面板和灯板。下面结合附图和实施方式对本申请作进一步说明。
请参阅图1和图2，图1为本申请实施例提供的显示面板的第一种结构示意图，图2为图1提供的显示面板中灯板的结构示意图。本申请实施例提供一种显示面板100，该显示面板100包括背板10和多个灯板20，每个灯板20设置在背板10上，每个灯板20包括呈阵列排布的多个灯珠230、叠设的第一基板210和第二基板220，多个灯珠230设置于第一基板210一侧，第二基板220设置于第一基板210背离灯珠230的一侧，第一基板210包括超出第二基板220的第一部分211，第二基板220包括超出第一基板210的第二部分221，其中，一灯板20中的第一部分211与相邻的另一个灯板20中的第二部分221拼接，两个灯板中相邻的且位于最外侧的两列灯珠之间的距离在预设范围内，且这两列灯珠230在拼接方向上齐平。通过将相邻的两个灯板20通过第一部分211和第二部分221重叠设置，可以将多个灯板20拼接起来，且拼接后两侧相邻的两列灯珠230之间的距离在预设范围之内，使得相邻拼接的灯板20之间的拼接缝可以通过灯珠230进行遮挡，以此，使得多个灯板20拼接后不会出现拼接缝，进而可以减小封接缝对显示面板100的影响，避免了拼缝暗影的存在，增加了显示效果。
需要说明的是，第一基板210的厚度和第二基板220的厚度相同，这样可以使得多组灯板20拼接后在同一水平方向上，避免了拼接后的灯板20出现断层的问题。
背板10包括底壁110和围绕底壁110设置的侧壁，侧壁包括相对设置的第一侧壁130和第二侧壁120，底壁110靠近第一侧壁130的一端设置有第一凸块140，第二侧壁120上设置有第二凸块150，第二凸块150与底壁110间隔设置以形成卡槽。
灯板20中的发光区域212包括依次设置的第一列灯珠2121、第一行灯珠2122、第二列灯珠2123和第二行灯珠2124，第一基板210包括依次设置的第五侧边、第六侧边、第七侧边和第八侧边。第一列灯珠2121和第五侧边相对设置，且第一列灯珠2121和第五侧边之间形成第一边缘区域2111。第一行灯珠2122和第六侧边相对设置，且第一行灯珠2122和第六侧边之间形成第二边缘区域2112，即第一部分211包括靠近第一列灯珠2121的第一边缘区域2111和靠近第一行灯珠2122的第二边缘区域2112。第二部分221包括靠近第二列灯珠2123的第三边缘区域2211和靠近第二行灯珠2124的第四边缘区域2212。
其中，任意一个灯板在第一方向上或在第二方向上，第一列灯珠2121和第五侧边之间的第一距离小于或等于相邻两个灯珠230之间的距离，即第一边缘区域2111中与第一列灯珠2121相对的外边缘到第一列灯珠2121的第一距离小于或等于相邻两个灯珠230之间的距离。
第一行灯珠2122和第六侧边之间的第二距离小于或等于相邻两个灯珠230之间的距离，即第二边缘区域2112中与第一行灯珠2122相对的外边缘到第一行灯珠2122的第二距离小于或等于相邻两个灯珠230之间的距离。
第三边缘区域2211中与第二列灯珠2123相对的外边缘到第二列灯珠2123的第三距离小于或等于相邻两个灯珠230之间的距离。
第四边缘区域2212中与第二行灯珠2124相对的外边缘到第二行灯珠2124的第四距离小于或等于相邻两个灯珠230之间的距离。
需要说明的是，通过将第一距离、第二距离、第三距离和第四距离设置成小于或等于相邻两个灯珠230之间的距离，可以使得相邻灯板20在拼接区域拼接后，两侧相邻的两列灯珠230之间的距离与一个灯板20上的相邻两列灯珠230之间的距离相近，可以避免拼接缝的位置离灯珠230的距离太远，从而可以使得拼接后的灯板20在视觉上显示不出拼接缝。
在其他一些实施例中，第二列灯珠2123与第七侧边重合设置，第二行灯珠2124和第八侧边重合设置。即第二列灯珠2123上的灯珠230到第一基板210中与第二列灯珠2123相对的外边缘的距离为零，第二行灯珠2124上的灯珠230到第一基板210中与第二行灯珠2124相对的外边缘的距离为零。通过将第二列灯珠2123与第七侧边重合设置，第二行灯珠2124和第八侧边重合设置，可以使得拼接后的拼接缝被灯珠230遮挡，从而解决拼缝暗影的问题。可以理解的是，第二列灯珠2123与第七侧边不一定是重合的，也可以是第二列灯珠2123与第七侧边的距离在一定的预设范围内，另第二行灯珠2124和第八侧边也不一定是重合的，也可以是第二行灯珠2124与第八侧边的距离在一定的预设范围内，具体的设置可以根据实际情况进行设置，在此不作具体的限制。
在一些实施例中，第一距离和第三距离均等于相邻两个灯珠230之间的距离，第二距离和第四距离为零。通过这样设置可以使得多个灯板20沿着垂直于第一列灯珠2121的第一方向上一直拼接。
在一些实施例中，第一距离和所述第三距离为零，第二距离和第四距离均等于相邻两个所述灯珠230之间的距离。通过这样设置可以使得多个灯板20沿着垂直于第一行灯珠2122的第二方向上一直拼接。
在其他一些实施例中，第一距离、第二距离、第三距离和第四距离均等于相邻两个灯珠230之间的距离。通过这样设置可以使得多个灯板20沿着垂直于第一列灯珠2121的第一方向上和垂直于第一行灯珠2122的第二方向上一直拼接，这样也可以使得拼接后的每个拼接缝都设置在灯珠230的边缘处，从而可以使得灯珠230遮挡住拼接缝，以解决拼缝暗影的问题。
示例性的，请继续参阅图3至图5，图3为图1提供的显示面板中多个灯板的第一种拼接的结构示意图，图4为图1提供的显示面板中多个灯板的第二种拼接的结构示意图，图5为图1提供的显示面板中多个灯板的第三种拼接的结构示意图。如图3所示，多个灯板20包括第一方向设置的第一灯板201和第二灯板202，第二灯板202中的第一边缘区域2111拼接在第一灯板201中的第三边缘区域2211上。第一灯板201中的第二列灯珠2123和第二灯板202中的第一列灯珠2121之间的距离在预设范围内，且第一灯板201中的第二行灯珠2124和第二灯板202中的第二行灯珠2124在第一方向上齐平。即第一灯板201中靠近第三边缘区域2211的灯珠230和第二灯板202中靠近的第一边缘区域2111的灯珠230之间的距离在预设范围内，且第一灯板201中靠近第四边缘区域2212的灯珠230和第二灯板202中靠近第四边缘区域2212的灯珠230在第一方向上齐平。
当灯板20安装至背板10上时，第一边缘区域2111设置在第一凸块140远离底壁110的一侧，第三边缘区域2211与卡槽相适配，第二基板220中与第一列灯珠2121重合的侧边与第一凸块140远离第一侧壁130的侧边抵接，第二列灯珠2123与第二凸块150远离第二侧壁120的侧边抵接，以使灯板20卡接于背板10。通过凸出设置的第一边缘区域2111、第二边缘区域2112、第三边缘区域2211和第四边缘区域2212和背板10中的卡槽和第一凸块140配合，以使灯板20可以卡接在背板10中，以防止灯板20安装在背板10后晃动。
如图4所示，多个灯板20包括第二方向设置的第三灯板203和第四灯板204，第一方向和第二方向垂直，第三灯板203中的第二边缘区域2112拼接在第四灯板204中的第四边缘区域2212上，第三灯板203中的第一行灯珠2122和第四灯板204中的第二行灯珠2124之间的距离在预设范围内，且第三灯板203中的第一列灯珠2121和第二灯板202的第一列灯珠2121在第二方向上齐平。即第一灯板201中靠近第二边缘区域2112的灯珠230和第二灯板202中靠近第四边缘区域2212的灯珠230之间的距离在预设范围内，第一灯板201中靠近第一边缘区域2111的灯珠230和第二灯板202中靠近第二边缘区域2112的灯珠230在第二方向上齐平。
当灯板20安装至背板10上时，第一灯板201的第一边缘区域2111和第二灯板202的第一边缘区域2111均设置在第一凸块140远离底壁110的一侧，第二灯板202的第三边缘区域2211和第一灯板201的第三边缘区域2211至少部分设置于卡槽内。在其他一些实施例中，第一灯板201的第三部分中与第一列灯珠2121重合的侧边与第一凸块140远离第一侧壁130的侧边抵接，第二灯板202的第二列灯珠2123与第二凸块150远离第二侧壁120的侧边抵接。
如图5所示，多个灯板20包括第一灯板201、第二灯板202、第三灯板203和第四灯板204。第一灯板201和第二灯板202设置在第一方向上，第三灯板203和第四灯板204设置在第一方向上，第一灯板201和第三灯板203设置在第二方向上，以及第二灯板202和第四灯板204设置在第二方向上。其中，第二灯板202中的第一边缘区域2111拼接在第一灯板201中的第三边缘区域2211上，第四灯板204中的第一边缘区域2111拼接在第三灯板203中的第三边缘区域2211上，第三灯板203中的第二边缘区域2112拼接在第一灯板201中的第四边缘区域2212上，第四灯板204中的第二边缘区域2112拼接在第二灯板202中的第四边缘区域2212上。
可以理解的是，显示面板100可以是任意多个灯板20进行拼接，拼接的数量和拼接的方向都可以根据需要进行设置，并不限制于上述示例，在此不作具体地限定。
如图2所示，本申请实施例还提供一种灯板20，该灯板20包括呈阵列排布的多个灯珠230、叠设的第一基板210和第二基板220，多个灯珠230设置于第一基板210一侧，第二基板220设置于第一基板210背离灯珠230的一侧，第一基板210包括超出第二基板220的第一部分211，第二基板220包括超出第一基板210的第二部分221。
其中，发光区域212包括依次设置的第一列灯珠2121、第一行灯珠2122、第二列灯珠2123和第二行灯珠2124，第一列灯珠2121到第一基板210中与第一列灯珠2121相对的外边缘的距离在预设范围内，第一行灯珠2122到第一基板210中与第一行灯珠2122相对的外边缘的距离在预设范围内，第二列灯珠2123到第一基板210中与第二列灯珠2123相对的外边缘的距离为零，第二行灯珠2124上的灯珠230到第一基板210中与第二行灯珠2124相对的外边缘的距离为零。
可以理解的是，灯板20的详情可见上述，在此不再赘续。
请继续参阅图6至图8，图6本申请实施例提供的显示面板的第二种结构示意图，图7为图6提供的显示面板中灯板的结构示意图，图8为图6提供的显示面板中背板的俯视图。本申请实施例还提供一种显示面板100，显示面板100包括背板10和多个灯板20，多个灯板20设置在背板10上，灯板20包括呈阵列排布的多个灯珠230、第一基板210和第二基板220，第二基板220设置在第一基板210的一侧与第一基板210叠设，即第二基板220在第一基板210上投影在第一基板210内。第一基板210包括与第一基板210叠设的叠设区域214和凸出第二基板220设置的边缘区域215，相邻的两个灯板20中的边缘区域215均与灯板20重叠设置形成拼接区域，拼接区域两侧相邻的两列灯珠230之间的距离在预设范围内，且拼接区域两侧相邻的两列灯珠230在拼接方向上齐平。通过将灯板20中第一基板210相对第二基板220凸出的部分设置与背板10进行连接，可以使得多个灯板20的拼接缝设置在背板10上，即非显示区，则可以使得多个拼接缝被遮挡，从而减小了拼接缝对显示面板100的影响。
背板10包括多条在竖直方向上间隔设置的第一加强筋111和在水平方向上间隔设置的第二加强筋112，第一加强筋111和第二加强筋112相互垂直的设置于背板10的背面上，交叉的第一加强筋111和第二加强筋112之间围设形成中空结构113，多个灯板20中的边缘区域215与第一加强筋111或第二加强筋112连接，且每个灯板20中的第二基板220设置在中空结构113内，以使在第一加强筋111或第二加强筋112处拼接的两侧相邻的两列灯珠230之间的距离在预设范围内，且拼接区域两侧相邻的两列灯珠230在拼接方向上齐平。通过背板10的设计可以定位和固定灯板20，降低多个灯板20的拼接难度，实现了显示面板100的薄型化。
可以理解的是，每个灯板20中第一基板210的边缘区域215的宽度小于第一加强筋111和第二加强筋112的宽度，这样可以使得相邻的两个灯板20在进行拼接时，拼接缝正好在第一加强筋111或第二加强筋112上，从而解决了拼接缝的影响。
需要说明的是，在一些实施例中，灯板20背面贴石墨烯散热，以解决散热问题，提高灯板20的使用寿命。
显示面板100还包括反射片60、支撑柱30、全贴合扩散板40和OC层50，其中，反射片60设置在灯板20上，多个支撑柱30间隔的设置在多个灯珠230之间，全贴合扩散板40设置在灯板20远离背板10的一侧，OC层50设置在全贴合扩散板40远离背板10的一侧。
以上对本申请实施例提供的显示面板和灯板进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上，本说明书内容不应理解为对本申请的限制。
