本申请属于通信设备技术领域，具体涉及一种电子设备及显示模组。
背景技术
随着用户需求的提升，电子设备配置的功能模块越来越多。这些功能模块能够使得电子设备的功能越来越多，进而能够满足用户更多的使用需求。

以下结合附图，详细说明本申请实施例公开的技术方案。
请参考图1～图2，本申请实施例公开一种显示模组，其包括NFC模块100和显示屏200，显示模组可以应用于电子设备中。
NFC模块100能够为电子设备提供NFC功能，NFC模块100能够使电子设备具有支付、模拟门禁、接触通过、浏览和链接等近场通讯功能。显示屏200用于显示图像。
其中，显示屏200包括基板层210和绝缘层220，基板层210是显示屏200的基础部件，基板层210能够承载安装显示屏200的各个部件，可选的，基板层210可以采用玻璃基板，因此其能够透光。绝缘层220设置在基板层210背向显示屏200显示方向的一侧，绝缘层220和基板层210沿两者的厚度方向叠置。NFC模块100包括NFC线圈110和NFC铁氧体120，其中，NFC线圈110设置在基板层210背向显示屏200显示方向的一侧，并且NFC线圈110是设置在基板层210的表面，由于基板层210设置有NFC线圈110的一侧还与绝缘层220叠置，NFC线圈110是位于绝缘层220内，绝缘层220能够起到保护NFC线圈110和基板层210的作用，防止NFC线圈110短路，同时NFC线圈110叠置在基板层210的表面，基板层210的结构不会为此而改变，从而保证了基板层210的结构完整性和稳定性，同时降低了基板层210的加工工艺难度。NFC铁氧体120设置在绝缘层220背向基板层210的一侧，通常，NFC铁氧体120采用具有高磁导率的材料制成，NFC铁氧体120可以起到聚束磁通量的 作用，通过增加显示模组内的磁场强度，有效增加NFC线圈110感应距离，使得显示模组具有更好的NFC感应性能。
本申请实施例所公开的显示模组中，NFC线圈110设置在基板层210上，并且NFC线圈110是位于绝缘层220内的，NFC线圈110有效地利用了绝缘层220的内部空间，不会额外增加显示模组的厚度，有利于显示模组的轻薄化，进而，有利于应用该显示模组的电子设备的轻薄化。同时，无需在基板层210上开设用于容置NFC线圈110的凹槽，保证了基板层210的结构稳定性和完整性，还降低了基板层210的加工工艺难度。NFC铁氧体120设置在绝缘层220背向基板层210的一侧，NFC铁氧体120与NFC线圈110具有一定的间距，使得NFC铁氧体120不会影响基板层210和绝缘层220的结构完整性。
可选的，在设置NFC线圈110时，可先将NFC线圈110沉积在基板层210背向显示屏200的显示方向一侧的表面后，再将绝缘层220沉积在基板层210上，这样也能够使绝缘层220将NFC线圈110包覆在内，进一步降低显示模组的工艺难度。
为了构成完整的显示屏200结构，在基板层210背向绝缘层220的一侧依次叠置有偏光层240和盖板230，盖板230、偏光层240、基板层210和绝缘层220沿它们四者的厚度方向依次叠置，盖板230能够起到保护显示模组的作用，偏光层240起到偏光作用，盖板230与偏光层240之间可通过透光连接胶231连接。透光连接胶可以为OCA胶层。
可选的，上述的NFC线圈110也可设置在盖板230的一侧或偏光层240在偏光层240厚度方向上的相对两侧，具体的，当NFC线圈110设置在盖板230上时，其可设置在盖板230背向显示屏200显示方向的一侧，相应的，绝缘层220也应设置在盖板230背向显示屏200显示方向的一侧，绝缘层220同样起到保护NFC线圈110的作用。当NFC线圈110设置在偏光层240上时，其可设置在偏光层240背向显示屏200显示方向的一侧，或是设置在偏光层240朝向显示屏200显示方向的一侧，相应的，绝缘层220根据NFC线圈110的具体位置选择设置在偏光层240背向显示屏200显示方向一侧或朝向显示屏 200显示方向的一侧，绝缘层220也应将NFC线圈110覆盖。
当NFC线圈110设置在偏光层240或是盖板230上时，也可以通过沉积的方式设置NFC线圈110，相应的，绝缘层220也通过沉积的方式沉积在NFC偏光层240或盖板230的表面。
应注意的是，通常在基板层210背向显示屏200显示方向的一侧还设置背光组件，背光组件是构成显示屏200的重要组件，其结构为公知技术，对此本申请不再赘述。
可选的，显示屏200包括显示区域200a和非显示区域200b，其中非显示区域200b是绕显示区域200a设置的，显示区域200a能够显示图像信息，非显示区域200b作为显示屏200的边界，起到保护显示区域200a的作用。相应的，显示区域200a在基板层210上具有对应的投影位置，该投影位置为显示投影，非显示区域200b在基板层210上也具有对应的投影位置，该投影位置为非显示投影，非显示投影也是将围绕显示投影设置。为了使NFC模块100的感应性能更强，NFC线圈110可呈多圈设置，同时为了使减小NFC线圈110对显示屏200显示效果的影响，多圈的NFC线圈110应在显示屏200的边缘延伸。
具体的，一部分NFC线圈110位于显示屏200的非显示区域200b，对应在基板层210上为非显示投影区域，另一部分NFC线圈110位于显示屏200的显示区域200a内，并且为显示区域200a靠近非显示区域200b的位置，对应在基板层210上为显示投影靠近非显示投影的位置，这样能够使NFC线圈110呈多圈设置的同时，减少NFC线圈110对显示屏200显示效果的影响。同时还能够缓解由于NFC线圈过于靠近显示屏200中心而造成显示屏200发生屏闪的问题。
应注意的是，为了在保证NFC线圈110的感应性能良好的前提下不额外增加显示模组的厚度，呈多圈设置的NFC线圈110的每一圈都应同层设置，避免NFC线圈110堆叠。
可选的，由于部分NFC线圈110进入到了显示屏200的显示区域200a内， 为了减小这部分NFC线圈110对显示区域200a的显示效果的影响，NFC线圈110可以采用透明走线，透明走线的NFC线圈110不会对显示区域200a的显示图像产生影响，从而有利于提高显示屏200的屏占比。具体的，透明走线的NFC线圈110的材质可采用氧化铟锡、TiAlTi或纳米银等，当采用氧化铟锡和TiAlTi作为NFC线圈110时，通常采用磁控溅射的方式将NFC线圈110沉积在基板层210上，当采用纳米银作为NFC线圈110时，通常采用溶液涂布法的方式将NFC线圈110沉积在基板层210上，采用上述工艺方法沉积NFC线圈110的方式能够使NFC线圈110的厚度进一步减小，相应的，绝缘层220的厚度也能够进一步减小，从而更进一步地降低显示模组的整体厚度。
上述的磁控溅射和溶液涂布法作为半导体工艺领域的公知技术，对此，本申请不再赘述。
可选的，NFC线圈110包括邻近显示屏200的中心的第一线圈端111和邻近显示屏200边缘的第二线圈端112，因此第一线圈端111和第二线圈端112之间具有一定的间距，当NFC线圈110呈多圈设置时，上述的间距会进一步增大，为了使NFC线圈110能够与电子设备的主板通讯连接，本申请实施例的显示模组还包括柔性电连接件300，柔性电连接件300的一端与NFC线圈110电连接，另一端电子设备的主板电连接。可选的，柔性电连接件300可以为柔性电路板
具体的，NFC线圈110的第二线圈端112由于邻近显示屏200的边缘，因此其能够直接与柔性电连接件300的一端电连接，而NFC线圈110的第一线圈端111由于与显示屏200的边缘具有一定的间距，因此第一线圈端111通过桥接走线400与柔性电连接件300的一端电连接。当NFC线圈110呈多圈设置时，桥接走线400会跨过部分的NFC线圈110，为了避免桥接走线400与部分NFC线圈110直接接触导致短路，在桥接走线400表面可包覆绝缘材料。随着NFC线圈110的圈数的增加，其第一线圈端111与显示屏200的边缘间距会增大，相应的，桥接走线400的长度也应增加，对于NFC线圈110的具体圈数和桥接走线400的长度，本申请不作限制。
可选的，上述的显示屏200还包括保护层250，保护层250叠置在绝缘层220背向基板层210的一侧。上述的桥接走线400由NFC线圈110的第二线圈端112引出后，桥接走线400会穿过绝缘层220，由于保护层250叠置在绝缘层220上，因此桥接走线400的第一部分处于绝缘层220中，第二部分处于保护层250中，保护层250将绝缘层220和桥接走线400包覆在内，保护层250能够起到封装绝缘层220和桥接走线400的目的，防止水气和氧气对NFC线圈110和桥接走线400腐蚀，达到保护NFC线圈110和桥接走线400的目的。具体的，保护层250可采用有机光阻类的封装玻璃。
值得注意的是，当桥接走线400由NFC线圈110的第一线圈端111引出后，其位于绝缘层220中的第一部分应设置为不与NFC线圈110接触，具体的，在第一部分与NFC线圈110之间具有绝缘层220将桥接走线400和NFC线圈110分隔开来，以防止桥接走线400和NFC线圈110接触短路。
可选的，基板层210的一端具有端部外沿210a，绝缘层220在基板层210上形成第一投影，端部外沿210a在基板层210上形成第二投影，第一投影和第二投影同层共面，第一投影位于第二投影的一侧，因此上述的端部外沿210a是绝缘层220的一端边缘向远离绝缘层220中心一侧延伸的部分，端部外沿210a上没有叠置绝缘层220。
端部外沿210a背向显示屏200显示方向的表面固定连接有第一电极片210b和第二电极片210c，端部外沿210a为第一电极片210b和第二电极片210c提供安装基础，第一电极片210b和第二电极片210c为电连接件，NFC线圈110通过第一电极片210b和第二电极片210c与柔性电连接件300连接，第一电极片210b和第二电极片210c上设置有连接胶600，使第一电极片210b和第二电极片210c与柔性电连接件300连接，进而与电子设备的主板通信连接。
具体的，NFC线圈110的第一线圈端111通过桥接走线400与第一电极片210b连接，因此，桥接走线400远离第一线圈端111的一端延伸至端部外沿210a上，NFC线圈110的第二线圈端112与第二电极片210c连接，柔性电连接件300同时与第一电极片210b和第二电极片210c连接，因此第一电极片 210b和第二电极片210c应靠近设置，以便于柔性电连接件300与两者同时连接，相应的，第一线圈端111和第二线圈端112的间距不宜过大，具体的，第一线圈端111和第二线圈端112在垂直于显示屏200的面上的投影的间距应设置较小，这样能够减小桥接走线400的长度，使本申请实施例所公开的显示模组的性能稳定性更佳。
可选的，上述的NFC线圈110、第一电极片210b和第二电极片210c同层设置，具体的，上述三者都可设置在基板层210背向显示屏200显示方向的一侧，这样能够减少NFC线圈110的冗余设置，同时不会额外增加本申请实施例所公开的显示模组的厚度。
可选的，上述的绝缘层220背向NFC线圈110的一侧叠置有缓冲层500，缓冲层500固定在绝缘层220上，NFC铁氧体120叠置在缓冲层500上，并且位于缓冲层500背向NFC线圈110的一侧，设置缓冲层500的目的在于保护显示屏200，具体的，缓冲层500可采用缓震泡棉等具有减震缓震功能的材料制成。
基于上述的显示模组，本申请实施例还公开了一种电子设备，包括上述的显示模组。
本申请实施例公开的电子设备可以为智能手机、平板电脑、电子书阅读器或可穿戴设备。当然，该电子设备也可以是其他设备，本申请实施例对此不做限制。
