其中，通过拼接形成凹槽Ho，并将发光二极管基板200设置在凹槽Ho内，达到提高拼接面板1000的平整度的效果。
可选的，发光二极管基板200的侧面与非弯折部Nz通过黑色胶体Hj连接。
其中，采用黑色胶体Hj设置在发光二极管基板200的侧面和非弯折部Nz之间，既可以使得发光二极管基板200更为稳定地设置在凹槽Ho内，又可以达到遮光的效果，提高显示对比度。
在一些实施例中，发光二极管基板200的侧面与非弯折部Nz可以采用非黑色胶体。
可选的，本申请实施例的第一种拼接面板1000的结构，以显示面板100为液晶显示面板为例进行说明。
显示面板100包括第一基板11和设置在第一基板11上方的第二基板12。
显示面板100还包括液晶13和框胶14。液晶13和框胶14均设置在第一基板11和第二基板12之间。框胶14封装于液晶13的周侧。非弯折部Nz包括液晶13。

可选的，在非弯折部Nz靠近弯折部Wz的一侧，第一基底111的部分超出第二基底121，以降低弯折部Wz的弯折半径。
需要说明的是，弯折侧是指显示面板100。
可选的，弯折部Wz包括液晶13。
也就是说，显示面板100将原本处于显示区的部分作为弯折部Wz，达到缩小边框的效果；另外采用显示面板100的显示部分作为弯折部Wz，可以减小弯折部Wz的弯折半径。
可选的，第二基板12可以是单纯的阵列基板，也可以是COA基板。其中，驱动电路层123可以包括设置在第二柔性层122上的扫描线、数据线、薄膜晶体管、电容和像素电极，部分的薄膜晶体管电连接像素电极。

由于弯折部Wz具有显示的部分，因此当显示面板100进行显示时，弯折部Wz也会显示，进而发光。发光二极管基板200设置在承托结构Ct上，会遮挡弯折部Wz发出的光，发光二极管基板200和第一基底111之间的间隙jx则采用黑色矩阵层113进行遮挡避免漏光。
可选的，显示面板100还包括第一偏光片151和第二偏光片152。第一偏光片151设置在第一基底111远离第二基板12的一面上。第二偏光片152设置在第二基底121远离第一基板11的一面上。
可选的，请参照图3，在本申请的一些实施例中，本实施与上述实施例的不同之处在于：弯折部Wz还包括框胶14。也就是说，液晶13和框胶14均位于弯折部Wz中，这样的设置可提高显示面板100的显示面积。
可选的，请参照图4，在本申请的一些实施例中，本实施例与上述各个实施例的不同之处在于：弯折部Wz包括框胶14，且不包括液晶13。也就是说，本实施例的拼接面板1000仅采用非显示区的部分进行弯折，即提高了显示面板100的显示面积，也进一步降低了拼接面板1000漏光的风险。
本申请实施例关于拼接面板1000的制备方法如下，本实施例以显示面板100为液晶显示面板为例进行说明，但不限于此。

步骤B1：提供至少两个显示面板，所述显示面板包括第一基板11和设置在第一基板11上方的第二基板12，显示面板100还包括液晶13和框胶14，液晶13和框胶14均设置在第一基板11和第二基板12之间，框胶14封装于液晶13的周侧；第一基板11包括第一基底111和第一柔性层112。第一柔性层112设置在第一基底111面向第二基板12的一面上；第二基板12包括第二基底121、第二柔性层122和驱动电路层123。第二柔性层122设置在第二基底121面向第一基板11的一面上。驱动电路层123设置在第二柔性层122面向第一基板11的一面上。
步骤B2：切割所述第一基底111和第二基底121分别对应于所述显示面板100的弯折区的部分，使得显示面板100对应于所述弯折区的部分形成平展状态的弯折部Wz；
步骤B3：弯折所述弯折部Wz，使弯折部Wz处于弯折状态；并将两个显示面板100的弯折部Wz相对且拼接设置形成承托结构Ct；
步骤B4：在承托结构Ct上设置发光二极管基板200，遮挡两个弯折部Wz之间的拼接。
这样便完成了本实施例的拼接面板1000的制备过程。
在一些实施例中，可选的，请参照图6，本实施例的拼接面板2000，其包括至少两个显示面板100和发光二极管基板200。
至少两个显示面板100拼接设置。显示面板100包括弯折部Wz和非弯折部Nz。弯折部Wz自非弯折部Nz的一侧向显示面板100的背面弯折设置。非弯折部Nz用于显示画面。
在两个拼接设置的显示面板100中，一显示面板100的弯折部Wz与另一显示面板100的弯折部Wz相对且拼接设置形成承托结构Ct。
发光二极管基板200设置在承托结构Ct上。
本实施例的拼接面板2000采用将显示面板100的部分进行弯折形成弯折部Wz，并将两个弯折部Wz拼接形成承托结构Ct，随后把发光二极管基板200设置在承托结构Ct上，以遮挡拼缝，进而达到在视觉上消除拼缝的效果。另外由于显示面板100将非显示功能层分进行弯折或弯折至显示面板100的背面，达到了缩小边框的效果。
需要说明的是，显示面板100的背面是相对于显示面板100的显示侧而言的；也即以显示面板100的显示侧的一面为正面。
可选的，发光二极管基板200可以是次毫米级发光二极管（Mini-LED）面板、微型发光二极管（Micro-LED）面板、有机发光二极管（OLED）面板或量子点发光二极管（QLED）面板。
可选的，非弯折部Nz高于承托结构Ct。在两个拼接设置的显示面板100中，两个非弯折部Nz的表面与承托结构Ct的表面界定形成一凹槽Ho。发光二极管基板200设置在凹槽Ho内。
其中，通过拼接形成凹槽Ho，并将发光二极管基板200设置在凹槽Ho内，达到提高拼接面板2000的平整度的效果。
可选的，发光二极管基板200的侧面与非弯折部Nz通过黑色胶体Hj连接。
可选的，显示面板100包括第一基板11和设置在第一基板11上方的第二基板12。第一基板11为盖板。第二基板12包括基底12c和依次设置在基底12c上的柔性层12d、驱动电路层12f、显示功能层12g和封装层12h。第一基板11设置在显示功能层12g上。柔性层12d包括超出基底12c的子层12d1。

在两个拼接设置的显示面板100中，驱动电路层12f的上表面、两个封装层12h的侧面和两个第一基板11的侧面形成凹槽Ho。
相较于上述实施例，本实施例的拼接面板采用发光二极管面板作为显示面板100，可以只切割基底12c对应于弯折区的部分，简化步骤。
本实施例的凹槽Ho具有更深的深度，发光二极管基板200设置在凹槽Ho，提高了拼接面板2000的平整度。
另外，由于凹槽Ho的深度大于发光二极管基板200的厚度，因此采用填充胶Tc填充在凹槽Ho内并覆盖发光二极管基板200，以保护和固定发光二极管基板200。
可选的，填充胶Tc的折射率等于第一基板11的折射率，以降低发光二极管基板200和显示面板100的显示差异。
本实施例的拼接面板采用将显示面板进行弯折形成弯折部，并将两个弯折部拼接形成承托结构，随后把发光二极管基板设置在承托结构上，以遮挡拼缝，进而达到在视觉上消除拼缝的效果；另外由于显示面板将非显示功能层分进行弯折或弯折至显示面板的背面，达到了缩小边框的效果。
以上对本申请实施例所提供的一种拼接面板进行了详细介绍，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的方法及其核心思想；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，综上所述，本说明书内容不应理解为对本申请的限制。
