具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体 实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例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，本领域普通技术人员在没有做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。
本申请公开的显示装置如图3所示，包括NFC模块100和显示屏200，其中：NFC模块100包括NFC线圈110和NFC铁氧体120。显示屏200包括依次叠置的线路基板层210、屏幕封装层220和第一绝缘层230。NFC线圈110设置在屏幕封装层220上，且位于第一绝缘层230之内，NFC铁氧体120设置在线路基板层210背向NFC线圈110的一侧。
在本申请中，线路基板层210为显示屏200的走线所在层，是显示画面的主体部分，线路基板层210的具体选材上可以是低温多晶硅(Low Temperature Poly-Silicon，LTPS)层，其具有超薄、重量轻、低耗电的优点，适配本申请显示装置的轻薄化需求。而屏幕封装层220可以是硬屏的封装玻璃层或者柔性屏的薄膜封装层，以对线路基板层210进行封装保护，以防止处于线路基板层210上的走线和各种沉积膜层受水氧腐蚀，两者为显示屏200能够实现显示功能的核心部件。
而NFC模块100的作用是发挥NFC功能，具体为NFC铁氧体120聚束磁通量，通过增加磁场强度有效增加感应距离，而NFC线圈110则用于产生NFC信号。本申请通过将NFC线圈110嵌入第一绝缘层230之内，使NFC线圈110无需单独占用叠置空间，进而避免NFC模块100对显示屏200叠置空间的占用，能够有效降低本申请显示装置厚度，经试验数据统计，采用本申请NFC模块100和显示屏200适配的设计方式，显示装置的厚度减薄约150μm左右，利于显示装置向轻薄化发展。
在具体工艺实施上，可以先采用气相沉积的方式将屏幕封装层220叠置于线路基板层210上，然后可以将NFC线圈110采用蒸镀的方式贴敷设置在屏幕封装层220上，再采用气相沉积的方式叠置第一绝缘层230于屏幕封装层220上，并使NFC线圈110处于第一绝缘层230内，以实现本申请显示装 置的组装。NFC线圈110的具体选材上可以是透明的氧化铟锡(Indium Tin Oxide，ITO)、纳米银、TiAlTi等，作为替代的工艺手段，ITO和TiAlTi可以采取磁控溅射的方式设置在屏幕封装层220上，而纳米银可以采用涂液法设置在屏幕封装层220上。
在更为具体的实施方式中，如图1和图3所示，NFC线圈110沿显示屏200的边缘延伸、且呈多圈设置，显示屏200包括显示区域200a和非显示区域200b，非显示区域200b围绕显示区域200a设置，NFC线圈110的一部分位于显示区域200a，NFC线圈110的另一部分位于非显示区域200b，这样的布局方式可以有效防止NFC线圈110进入显示区域200a中心而降低屏占比，并且规则走线的方式也有利于避免读卡闪屏的问题。
更为具体的，NFC线圈110为透明走线，以进一步提高屏占比，同时NFC线圈110采用蒸镀工艺可以灵活调节透明金属成分比例，以适配不同的工作场景。
在一些实施例中，如图1和图2所示，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的边缘的第二线圈端112。显示装置还包括第一柔性电路板300。
第一柔性电路板300的第一端连接在显示屏200的边缘，同时第一柔性电路板300与第二线圈端112电连接，第一线圈端111通过桥接走线400与第一柔性电路板300电连接。
第一柔性电路板300的设计可以将NFC模块100产生的NFC信号传递至外界芯片，以完成信号传输。其中第一柔性电路板300设置于显示屏200边缘，并配合桥接走线400同时连通第一线圈端111和第二线圈端112的布局方式，可以保证第一柔性电路板300在有效传输NFC信号的同时远离显示屏200中心，以避免干扰显示屏200工作。
进一步的，如图3所示，显示屏200还包括第一保护层240，第一保护层240叠置在第一绝缘层230上，具体为叠置于第一绝缘层230中相背于屏幕封装层220的一侧上。桥接走线400的第一部分设置于第一绝缘层230内， 桥接走线400的第二部分设置于第一保护层240内。
第一保护层240可以根据具体的工作场景不同而进行不同的选材，比如显示屏200的触控方式为incell内嵌式时，显示屏200的触控走线集成在线路基板层210和屏幕封装层220之间，此时第一保护层240可以设置为有机光阻层，以防止水氧腐蚀，在具体的工艺实施方式的第一保护层240可以采用旋涂方式进行叠置在第一绝缘层230上。而显示屏200的触控方式为oncell硬屏外嵌式触控时，显示屏200的触控走线位于第一绝缘层230的上方，此时第一保护层240可以采用与第一绝缘层230相同的材料制作，以提供绝缘保护，防止短路。
桥接走线400部分位于第一绝缘层230内的方式，可实现连接第一线圈端111的同时与NFC线圈110的其他部分保持间隔，使第一绝缘层230可防止桥接走线400与NFC线圈110之间的短路；桥接走线400的第一部分设置于第一绝缘层230内，桥接走线400的第二部分设置于第一保护层240内的方式，可以实现嵌入第一绝缘层230和第一保护层240之间，以防止桥接走线400对显示屏200叠置空间的占用，进一步减薄显示装置。
更进一步的，NFC线圈110可以是设置于显示屏200边缘的螺旋线，整体呈口字型或者回字型布局贴敷在屏幕封装层220上，并由显示区域200a向非显示区域200b逐圈围绕形成，这样第一线圈端111和第二线圈端112均设于屏幕封装层220上，即位于显示屏200在叠置方向的同一厚度上，以尽可能减少NFC线圈110在显示屏200在叠置方向的厚度，配合桥接走线400的连接方式，可使显示装置的减薄效果更佳。
同时，作为一种具体工艺手段，桥接走线400可以采用磁控溅射的方式设置在显示屏200上，也利于减少桥接走线400对叠置空间的占用。
更为具体的，如图1～图3所示，屏幕封装层220包括端部外沿221。第一绝缘层230于屏幕封装层220上形成第一投影，端部外沿221于屏幕封装层220上形成第二投影，第一投影与第二投影共面，且位于第二投影的一侧。
端部外沿221的朝向显示屏200显示方向的表面固定有第一电极片222 和第二电极片223，第一柔性电路板300的第一端与第一电极片222和第二电极片223电连接，第一线圈端111通过桥接走线400与第一电极片222电连接，第二线圈端112与第二电极片223电连接。第一柔性电路板300的第二端用于与电子设备的主板进行电连接。
这样，通过端部外沿221的设置可使第一电极片222和第二电极片223充分暴露，进而利于NFC线圈110与第一柔性电路板300之间的连接，而通过第一电极片222和第二电极片223作为中间传输介质，更利于NFC线圈110产生的信号传递至第一柔性电路板300上。
在具体的选材上第一电极片222和第二电极片223均可以采用如ITO、纳米银、TiAlTi等进行制作，在具体的工艺手段选用上，也可以采用蒸镀贴敷设置在屏幕封装层220的表面。
更进一步的，如图3所示，第一柔性电路板300的第一端搭接固定在第一电极片222和第二电极片223上，第一电极片222和第二电极片223的端面与第一柔性电路板300之间设置有胶体500，以保证连接更稳定，同时，胶体500能够避免第一柔性电路板300的第一端发生较大角度的折弯，从而起到保护第一柔性电路板300的作用。其中胶体500可选用立线胶作为粘接剂。
更进一步的，NFC线圈110、第一电极片222和第二电极片223同层设置，比如均设置于屏幕封装层220的表面，并位于第一绝缘层230内，以提高空间利用率，进一步的避免对显示屏200叠置空间的占用。
在一些实施例中，如图1所示，线路基板层210背向NFC线圈110的一侧叠置有弹性缓冲层600，NFC铁氧体120叠置在弹性缓冲层600上，且位于弹性缓冲层600背向NFC线圈110的一侧。这里弹性缓冲层600的设计可以起到缓冲作用，以避免线路基板层210受到磕碰的损伤，同时弹性缓冲层600的设计还可以增大NFC线圈110与NFC铁氧体120之间的磁感距离，以增强传输信号。
这里还需要指出的是，实现线路基板层210、屏幕封装层220、第一绝缘 层230和第一保护层240之间依次叠置的具体工艺手段，可采用气相沉积的方式实现。
