本申请提供一种显示面板、该显示面板的制作方法和采用了该显示面板的显示屏，以下分别进行详细说明。
首先，本申请实施例提供了一种显示面板，所述显示面板包括第一基板、第二基板和连接件；所述第一基板和所述第二基板相对设置，所述连接件设置在所示第一基板和所述第二基板之间，用于固定贴合所述第一基板和所述第二基板；所述第一基板包括本体和拼接部，所述拼接部位于所述本体侧边；所述第二基板上设有金属导线，所述第二基板包括平坦部和弯折部，所述弯折部位于所述平坦部侧边，所述平坦部位于所述本体下方，所述弯折部位于所述拼接部下方，所述第一基板的长度大于所述第二基板上平坦部的长度。
本申请实施例中通过在第二基板上设置第一基板，并使第一基板上的拼接部位于第二基板的弯折部上方，在将多个显示面板拼接成大尺寸的显示屏时，多个显示面板的第一基板之间发生接触，由于拼接部具有一定的长度，且拼接部位于第二基板的弯折部上方，在多个显示面板进行组合拼接时，能使两个相邻的第二基板之间能留有一定的空间，防止第二基板上的弯折部被相邻的显示面板碰撞和挤压，避免因为挤压弯折部而造成的金属导线断裂，另外利用拼接部进行拼接和对位，提高了拼接的精确性，降低了拼接难度。
在一个具体实施例中，显示面板为LED显示面板，如图2所示，显示面板100包括第一基板101、第二基板201和连接件301。第一基板101上包括发光件210，发光件210包括多个阵列排布的LED202。第一基板101和第二基板201相对设置，并通过连接件301固定贴合，第二基板201上制作有金属导线（图中未示出）。在本申请实施例中，连接件301为光学胶（Optically Clear Adhesive，OCA），具有高透光率和高黏着力等优点，连接件301也可以使用其他的材料，只要其透光率和黏着力满足实际需求即可，此处不做限定。
第一基板101包括本体102和拼接部103，拼接部103位于本体102的侧边，第二基板201包括平坦部211和弯折部212，弯折部212位于平坦部211的侧边，弯折部212位于平坦部211的侧边，平坦部211位于本体102下方，弯折部212位于拼接部103下方，第一基板的长度d1大于第二基板上平坦部的长度d2。
第二基板201的材料为聚酰亚胺，通过在第二基板201上进行电路制作后，第二基板201上分布有金属导线。在将多个显示面板100进行拼接时，多个显示面板100上的第一基板101之间接触，由于拼接部103具有一定的长度d3，且拼接部103位于第二基板201的弯折部212上方，能使两个相邻的第二基板201之间能留有一定的空间，即两个相邻第二基板201上的平坦部211之间能保持一定的距离e，避免了第二基板201上的弯折部212被相邻的显示面板碰撞和挤压，从而使弯折部212上的金属导线不会因为挤压而发生断裂。
在本申请的一些实施例中，第一基板101的材料为玻璃，其具有良好的透光性且刚度较大，第一基板101的刚度大于第二基板201的刚度，在拼接多个显示面板时可以减小第一基板101上拼接部103因为被挤压而发生的变形，减小了弯折部212被挤压后造成金属导线断裂的风险，可以理解的是，第一基板101也可以采用树脂等其他材料，只要其透光性能和刚度能满足实际需求，此处不做限定。
在本申请的一些实施例中，如图2所示，拼接部103的长度d3不小于多个LED202中相邻两个LED202之间的距离d4。如果拼接部103的长度太小，在将多个显示面板进行拼接后，两个相邻的第二基板201之间的空间会过小，即两个相邻第二基板201上的平坦部211之间的距离e过小，当弯折部212的曲率较大时，容易造成第二基板201上的弯折部212被相邻的显示面板挤压。当拼接部的长度d3等于多个LED202之间的距离d4时，既能保证弯折部212上的金属导线不易被挤压折断，又能使拼接后的大尺寸显示屏具有良好的显示均匀度。
在本申请的一些实施例中，如图3所示，拼接部103的长度d3等于弯折部212的曲率半径R，如此能够保证在将多个显示面板100进行拼接后，两个相邻的第二基板201之间会留有足够的空间，最大程度上减少了因为弯折部212被挤压而发生的金属导线断裂风险。可以理解的是，拼接部103的长度d3也可以大于弯折部212的曲率半径R，但是长度d3过大会造成两个相邻的显示面板100在拼接处的像素间距过大，影响拼接后大尺寸显示屏的显示效果。
在本申请的一些实施例中，如图3所示，第一基板101上的本体102和拼接部103一体成型，如此可以简化第一基板101的制作工艺。可以理解的是，本体102和拼接部103也可以是两个独立的部分，本体102和拼接部103之间通过粘合剂粘合固定。
在本申请的一些实施例中，如图4所示，显示面板100还包括支撑板401，支撑板401位于第二基板201上平坦部211的下方，支撑板401可以增加显示面板结构的刚度，使显示面板的结构更加稳定。支撑板401的材料可以是玻璃，也可以是树脂等具有一定刚度的材料，具体此处不做限定。
在本申请的一些实施例中，如图4所示，支撑板401的长度d5等于第二基板201上平坦部211的长度d2，如此既能使支撑板401对第二基板201有良好的支撑，又能节省支撑板401的材料，可以降低显示面板100的制造成本。
在本申请的一些实施例中，如图4所示，第一基板101上包括遮光件302，遮光件302位于第一基板101和第二基板201之间，遮光件302位于第一基板101和多个LED202之间，遮光件302上具有多个镂空区域303，多个镂空区域303与多个阵列排布的LED202 一一对应。遮光件302能使第二基板201上多个LED202发出的光只从多个镂空区域303中通过，防止相邻LED之间的颜色混杂，提升了显示面板100的对比度；另外，在相邻两块显示面板100的拼接处，由于有遮光件302的存在，能使拼接处的颜色保持一致，避免了拼接组成的大尺寸显示屏因为拼接处的颜色差异而造成的图像分割感。遮光件302需要有良好的遮光效果，其材料可以为黑色树脂，也可以是含铬的合金等能较好吸收光的材料。
在本申请的一些实施例中，如图4所示，多个镂空区域303中每个镂空区域的面积和多个阵列排布的LED202中每个LED的面积相同，如此既可以使遮光件302能达到最好的遮光效果，又能保证显示面板的亮度，使显示面板的发光效率不会因为遮光件302而降低。
本申请实施例还提供了一种显示屏，显示屏由本申请实施例中的显示面板拼接组成，如图4所示，相邻的两个显示面板100通过一个第一基板101上的拼接部103，和另一个第一基板101上的本体102之间接触，以进行组合拼接，可以理解的是，相邻的两个显示面板100也可以是两个第一基板101上的拼接部103之间接触，以进行组合拼接。在两个显示面板100的拼接处可以用胶将显示面板100之间进行固定，以提升拼接组成的大尺寸显示屏的结构稳定性。
本申请实施例中还提供一种显示面板的制作方法，该显示面板的制作方法其包括如下步骤：
在第二基板上进行电路制作，使所述第二基板上分布有金属导线；
提供第一基板和第二基板；
在第二基板上进行电路制作，使所述第二基板上分布有金属导线；
将所述第一基板与所述第二基板贴合，并将所述第一基板和所述第二基板用连接件固定；
在所述第二基板的边缘处，切除部分所述第二基板；
在所述第二基板的边缘处对其进行折弯，形成平坦部和弯折部，并使所述平坦部的长度不大于所述第一基板上本体的长度，所述平坦部上方对应所述第一基板的本体，所述弯折部上方对应所述第一基板的拼接部。
图6为本申请实施例中显示面板的制作方法的一个实施例流程图，如图所示，该方法包括：
S101、提供第一基板和第二基板，所述第一基板上包括具有多个镂空区域的遮光件；
在本申请实施例中，第二基板201的材料为聚酰亚胺，第一基板101的材料可以是玻璃或者树脂；通过光刻工艺在第一基板101上形成遮光件302，形成的第一基板101的侧视图如图7所示。
S102、在第二基板上进行电路制作。
在第二基板201上进行电路制作，使所述第二基板201上分布有金属导线，其采用的工艺可以是低温多晶硅（Low Temperature Poly-silicon，LTPS）工艺，氧化铟镓锌（IndiumGalliumZincOxide，IGZO）工艺等。
在本申请实施中，第二基板201上完成电路制作后，将多个LED转移至所述第二基板201上，形成发光件。LED202的转移可以采取如下方法：将多个LED倒入装有溶液的容纳槽中，容纳槽的底部设有转移基板，转移基板上设有多个孔洞，容纳槽的底部设有抽滤口和抽滤装置，抽滤装置使容纳槽的溶液向抽滤口流动，带动LED流向容纳槽底部，并嵌入进转移基板的孔洞中，最后通过将转移基板和第二基板进行对位，将LED转移至第二基板上预设的LED固定位置中，该方法在转移尺寸较小的LED芯片时也能有较高的效率。
最终形成的第二基板的结构如图8和图9所示。
S103、将所述第一基板与所述第二基板贴合，并将所述第一基板和所述第二基板用连接件固定。
将第一基板101与第二基板201对位贴合，然后通过连接件将第一基板和第二基板固定，连接件采用光学胶（OCA），可以理解的是连接件也可以是其他的具有良好透光性和黏着力的胶。
在本申请的一些实施例中，在第一基板101上还设有包括多个镂空区域303的遮光件302，在将第一基板101与第二基板201对位贴合时，使LED芯片刚好位于遮光件302的镂空位置。
遮光件302的材料可采用有色金属铬或者是含铬合金，有色金属铬或含铬合金对光有着良好的吸收作用，遮光件302的材料也可采用黑色树脂，使用黑色树脂比使用含铬金属更加环保，同时成本更低。通过对遮光件302进行团案化处理，在遮光件302上形成多个镂空区域303，具有多个镂空区域303的遮光件302可以通过光刻工艺来制作。
第一基板101与第二基板201贴合之后的结构如图10所示。
S104、在所述第二基板的边缘处，切除部分所述第二基板。
为了方便后续对第二基板201进行弯折，如图5所示，对处于显示面板的弯折区的部分第二基板213进行切除，保留待弯折的部分214。
S105、在所述第二基板的边缘处对其进行折弯，形成平坦部和弯折部。
在第二基板的边缘处对其进行弯折，并使所述第一基板的长度大于所述第二基板上平坦部的长度，所述平坦部上方对应所述第一基板的本体，所述弯折部上方对应所述第一基板的拼接部。
如图4和图5所示，对第二基板201上待弯折的部分214进行折弯后，折弯后形成平坦部211和弯折部212，平坦部211位于本体102的下方，弯折部212位于拼接部103的下方，第一基板101的长度d1大于第二基板201上平坦部211的长度d2，如此可以在拼接多个显示面板100时，使两个相邻的第二基板201之间能留有一定的空间，避免了第二基板201上的弯折部212被相邻的显示面板碰撞和挤压。
在第二基板201的边缘处对其进行折弯后，形成的结构如图11所示。
显示面板100制作完成后，将多个显示面板100拼接在一起，如图12和图13所示，形成大尺寸显示屏。
本申请实施例通过在第二基板201上设置第一基板101，并使第一基板101上的拼接部103位于第二基板201的弯折部212上方，在将多个显示面板100拼接成大尺寸的显示屏时，多个显示面板100的第一基板101之间发生接触，由于拼接部103具有一定的长度，且拼接部103位于第二基板201的弯折部上方，在多个显示面板100进行组合拼接时，能使两个相邻的第二基板201之间能留有一定的空间，避免了第二基板201上的弯折部212被相邻的显示面板碰撞和挤压，从而解决了因为挤压弯折部212造成的金属导线断裂的问题，另外利用拼接部103进行拼接和对位，提高了拼接的精确性，降低了拼接难度。
以上对本申请提供的一种显示面板、显示面板的制作方法和显示屏进行了详细介绍，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的技术方案及其核心思想；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的技术方案的范围。
