本申请涉及显示技术领域，尤其涉及一种拼接显示面板及电子设备。
随着显示技术的发展，大尺寸拼接显示面板逐渐成为热点。目前，拼接显示面板主要有LCD（Liquid Crystal Display，液晶显示器）拼接显示面板、LED（Light-Emitting Diode，发光二极管）拼接显示面板、OLED（Organic Light-Emitting Diode有机发光二极管）拼接显示面板，既能单屏单独显示、或者任意组合显示，又能拼接成超大屏幕显示。
在传统拼接显示面板中，有窄边框（Border）和宽边框的设计区别，传统拼接显示面板一般采用窄边框，并且以此为基础派生出各类消缝技术。然而，目前的拼接显示面板中拼缝的宽度在减小，但是，拼接显示面板中的拼缝仍无法消除，视觉效果上始终存在缺陷，即拼接显示面板在显示时，拼缝所在区域为黑色，即显示画面上存在暗影，影响显示画面的连续性以及完整性。
故，有必要提出一种新的技术方案，以解决上述技术问题。
本申请实施例提供一种拼接显示面板及电子设备，用于改善拼接显示面板在拼缝处的暗影。

由于第一显示模块10和第二显示模块20拼接形成拼缝P，因此，本申请实施例将第三显示模块30设置在第一显示模块10和第二显示模块20的上方，并遮挡拼缝P，并且，由于在第三显示模块30靠近第一显示模块10和第二显示模块20的一面设置有第一磁性构件401a，第一磁性构件401a与位于第一基板101上的第二磁性构件401b相吸，从而实现快速拼接。本申请实施例提供的拼接显示面板100不仅可以改善拼接显示面板在拼缝P处的暗影，还可以实现快速拼接，从而提高生产效率。
应该理解的是，本申请实施例中第一显示模块10和第二显示模块20具有相同的结构，为了方便进行阐述，本申请实施例将其区分为第一显示模块10和第二显示模块20。
进一步的，第一基板101包括靠近第二显示模块20的第一侧面101a，第二基板102包括靠近第二显示模块20的第二侧面102a，第一基板101的第一侧面101a到第二显示模块20的距离小于第二基板102的第二侧面102a到第二显示模块20的距离。第二基板102的第二侧面102a、第一基板101靠近第二基板102裸露的表面与第二显示模块20靠近第一显示模块10的侧面围设形成凹槽N，第二磁性构件401b位于凹槽N内。并且，第二磁性构件401b贴合第二基板102的第二侧面102a、第一基板101靠近第二基板102裸露的表面以及第四基板202远离第三基板201的一面。将第二磁性构件401b设置在凹槽N内，因此，不会增加拼接显示面板100的厚度，从而实现拼接显示面板100的轻薄化。

在一些实施例中，第三显示模块30包括阵列基板303、柔性电路板302和显示单元301，显示单元301设置在阵列基板303上，且显示单元301和阵列基板303电性连接，柔性电路板302与阵列基板303电连接，柔性电路板302通过第一磁性构件401a的过孔h设置于拼缝P内。柔性电路板302设置在第一显示模块10和第二显示模块20之间。将柔性电路板302设置在第一显示模块10和第二显示模块20拼接的拼缝P处，因此，不会增加第三显示模块30的厚度，从而实现拼接显示面板100的轻薄化。
请参考图2，图2为本申请实施例提供的拼接显示面板的第二种结构示意图。拼接显示面板具有第一显示部分A1和第二显示部分A2，第一显示部分A1位于第二显示部分A2的两侧，其中，第二显示部分A2为拼接显示部分。
拼接显示面板100包括第一显示模块10、第二显示模块20、第三显示模块30、第一磁性构件401a和第二磁性构件401b。第一显示模块10包括第一基板101和第二基板102，第二基板102设置在第一基板101上。第二显示模块20位于第一显示模块10的一侧，第二显示模块20包括第三基板201和第四基板202，第四基板202设置在第三基板201上，第二显示模块20和第一显示模块10拼接形成拼缝P。第三显示模块30设置在第一显示模块10和第二显示模块20的上方，且第三显示模块30遮挡拼缝P。第一磁性构件401a位于第三显示模块靠近第一显示模块10和第二显示模块20的一面。第二磁性构件401b位于第一基板101上，第一磁性构件401a与第二磁性构件401b相吸。
由于第一显示模块10和第二显示模块20拼接形成拼缝P，因此，本申请实施例将第三显示模块30设置在第一显示模块10和第二显示模块20的上方，并遮挡拼缝P，并且，由于在第三显示模块30靠近第一显示模块10和第二显示模块20的一面设置有第一磁性构件401a，第一磁性构件401a与位于第一基板101上的第二磁性构件401b相吸，从而实现快速拼接。本申请实施例提供的拼接显示面板100不仅可以改善拼接显示面板在拼缝P处的暗影，还可以实现快速拼接，从而提高生产效率。
进一步的，第一显示模块10还包括第一偏光片103，第一偏光片103设置在第二基板102上。第二显示模块20还包括第二偏光片203，第二偏光片203设置在第四基板202上。第二磁性构件401b设置在第一基板101上且贴合第二基板102的第二侧面102a，第二磁性构件401b与第二基板102平齐设置。第一磁性构件401a的一部分贴合第二磁性构件401b远离第一基板101的一面，且第一磁性构件401a贴合第一偏光片103的第一侧面103a和第二偏光片203的第一侧面203a，第一磁性构件401a与第一偏光片103平齐设置。
拼接显示面板100还可以包括设置在第一基板101和第二基板102之间的第一液晶层104和设置在第一基板101远离第二基板102的一面的第三偏光片105；以及拼接显示面板100包括设置在第三基板201和第四基板202之间的第二液晶层204和设置在第三基板201远离第四基板202的一面的第四偏光片205。
需要说明的是，本申请实施例的第一基板101为驱动基板，第二基板102为彩膜基板，第三基板201为驱动基板，第四基板202为彩膜基板。驱动基板可以包括衬底和设置在衬底上的驱动电路层。第三显示模块30为Mini
LED显示模块或Micro LED显示模块。第三显示模块30包括柔性电路板302、阵列基板303和显示单元301，柔性电路板302设置在第一显示模块10和第二显示模块20之间。将柔性电路板302设置在第一显示模块10和第二显示模块20拼接的拼缝P处，因此，不会增减第三显示模块30的厚度，从而实现拼接显示面板100的轻薄化。
请参考图1或图2，柔性电路板302设置在阵列基板远离显示单元301的一面，柔性电路板302通过第一磁性构件401a的过孔h设置于拼缝P内。本申请实施例提供的柔性电路板设置于阵列基板远离显示单元301的一侧，因此，不会增减第三显示模块30的厚度，进一步实现了拼接显示面板100的轻薄化。
请参考图3，图3为本申请实施例提供的拼接显示面板的第三种结构示意图。柔性电路板302设置于阵列基板303的侧面，柔性电路板302由阵列基板303的侧面通过第一磁性构件401a的过孔h弯折至拼缝P内。第三显示模块30还包括平坦化层304，平坦化层304设置在阵列基板303远离显示单元301的一侧，其中，平坦化层304用于平坦柔性电路板302由阵列基板303的侧面通过第一磁性构件401a的过孔h弯折至拼缝P内时，阵列基板303与第一磁性构件401a形成的间隙。本申请实施例中的柔性电路板302由阵列基板303的侧面通过过孔h弯折至拼缝P内时，阵列基板303远离显示单元301的一面和第一磁性构件401a之间具有间隙，利用平坦化层304平坦间隙，从而提高拼接显示面板100的平整度，进一步提高了拼接显示面板100的稳定性。
进一步的，第一基板101包括靠近第二显示模块20的第一侧面101a，第二基板102包括靠近第二显示模块20的第二侧面102a，第一基板101的第一侧面101a到第二显示模块20的距离小于第二基板102的第二侧面102a到第二显示模块20的距离。第二基板102的第二侧面102a、第一基板101靠近第二基板102裸露的表面与第二显示模块20靠近第一显示模块10的侧面围设形成凹槽N，第二磁性构件401b位于凹槽N内。并且，第二磁性构件401b贴合第二基板102的第二侧面102a、第一基板101靠近第二基板102裸露的表面以及第四基板202远离第三基板201的一面。
在本申请实施例提供的拼接显示面板100中，通过在凹槽N内设置第二磁性构件401b，且第二磁性构件401b贴合第二基板102的第二侧面102a且与第二基板102平齐设置；第一磁性构件401a贴合第一偏光片103的第一侧面103a和第二偏光片203的第一侧面203a，以及第一磁性构件401a与第二磁性构件401b相吸，从而实现快速拼接。本申请实施例提供的拼接显示面板100不仅可以改善拼接显示面板在拼缝处的暗影，还可以实现简便、快速拼接，从而提高生产效率。
在一些实施例中，第一磁性构件401a包括磁性涂层、磁性胶层和磁铁中的至少一种。第二磁性构件401b包括磁性涂层和磁性胶层中的至少一种。其中，磁性涂层由磁性颗粒与有机聚合物混合制成。磁性胶层由磁性颗粒与光学胶混合制成。其中，磁性颗粒包括铁、钴、镍、锰或铁、钴、镍、锰的金属氧化物中的至少一种。
由于光学胶具有粘合作用，因此，可以将磁性颗粒混合于光学胶内，然后涂布于凹槽N内，再利用紫外光对混合有磁性颗粒的光学胶进行固化，由此形成磁性胶层，磁性胶层可以直接贴合于第一基板101和第二基板102的第二侧面102a，因此，当第一磁性构件401a和第二磁性构件401b为磁性胶层时，磁性胶层稳固贴合于第一基板101和第二基板102，从而提高了拼接显示面板100的稳定性。
另外，铁、钴、镍、锰或铁、钴、镍、锰的金属氧化物等磁性金属氧化物具有吸附能力强，且获取途径广等优点。
需要说明的，本实施例中的光学胶可以是有机硅胶、丙烯酸型树脂及不饱和聚酯、聚氨酯、环氧树脂中的一种或其任意组合。
请参阅图4，图4为本申请实施例提供的拼接显示面板的第四种结构示意图。第一磁性构件401a为磁性涂层或磁铁，拼接显示面板100还包括第一粘合层402a，第一粘合层402a设置在第一偏光片103的第一侧面103a和第二偏光片203的第一侧面203a。第一粘合层402a用于将磁性涂层或磁铁与第一偏光片103、第二偏光片203粘合。
第二磁性构件401b为磁性涂层。拼接显示面板100还包括第二粘合层402b。第二粘合层402b设置在第一基板101靠近第二磁性构件401b的一面，以及第二粘合层402b设置在第二基板102的第二侧面102a，第二粘合层402b用于将磁性涂层和第一基板101、第二基板102粘合。
在本申请实施例中，利用第一粘合层402a粘合第一磁性构件401a、第一偏光片103和第二偏光片203。利用第二粘合层402b粘合第二磁性构件401b、第一基板101和第二基板102。第一粘合层402a和第二粘合层402b用于防止第一磁性构件401a和第二磁性构件401b脱落，从而提高了拼接显示面板100的稳定性。
在一些实施例中，第二磁性构件401b的宽度小于或等于3微米。例如，第二磁性构件401b的宽度可以是0.5微米、1.0微米、1.2微米、1.5微米、2.2微米或3.0微米中的任意一者。本申请实施例将第二磁性构件401b的宽度设置为小于或等于3微米，使得第二磁性构件401b具备足够的宽度贴合第一基板101和第二基板102，防止第二磁性构件401b脱落，进一步提高了拼接显示面板100的稳定性。
请参考图5，图5为本申请实施例提供的拼接显示面板的第五种结构示意图。
第三显示模块30还包括磁性层305，磁性层305设置在第一显示模块10和第二显示模块20的上方，磁性层305与第一磁性构件401a相吸。
磁性层305的材料可以是超薄铁板、超薄钴片、超薄镍片、超薄锰片或具有铁、钴、镍、锰等金属氧化物的超薄器件。
本申请实施例在显示单元301的下方承载磁性层305，使得第三显示模块30可以和第一磁性构件401a磁性相吸，简化了拼接显示面板100的拼接步骤。
请参考图6，图6为本申请实施例提供的电子设备的平面结构示意图。
电子设备1000包括壳体200和设置在壳体200内的拼接显示面板，拼接显示面板为上述任一实施例所述的拼接显示面板100，此处不再赘述。
需要说明的是，本申请实施例提供的电子设备1000可以为智能手机(smartphone)、平板电脑(tablet
personal computer)、移动电话(mobile phone)、视频电话机、电子书阅读器(e-book reader)、台式计算机(desktop
PC)、手提电脑(laptop PC)、上网本(netbook computer)、工作站(workstation)、服务器、个人数字助理(personal digital assistant)、便携式媒体播放器(portable multimedia player)、MP3播放器、移动医疗机器、照相机、游戏机、数码相机、车载导航仪、电子广告牌、自动取款机或可穿戴设备(wearable
device)中的至少一个，特别的，电子设备可以是大型显示设备。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
