本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施方式及实施方式中的特征可以相互组合。
参见图1，本实施例提供了一种电子设备100的整体结构的示意图。本实施例中，所述电子设备100包括显示屏1、壳体本体2及NFC标签3(参考图3)。所述显示屏1安装在壳体本体2上，所述NFC标签3贴附在所述壳体本体2上。本实施例中，为描述方便，将图1中从左到右的方向定义为三维坐标系的x轴，从前到后的方向定义为三维坐标系的y轴，将垂直x轴、y轴的轴定义为三维坐标系的z轴。在一实施例中，所述NFC标签3贴附在壳体本体2的右边，如此方便惯用右手的用户使用NFC标签3。在另一实施例中，所述NFC标签3贴附在壳体本体2的左边，可方便惯用左手的用户使用NFC标签3。
请参考图2所示，为本申请一实施例中显示屏1的结构示意图。所述显示屏1包括显示面板12、导光片13、反射膜14、支撑板11，所述显示面板12、导光片13、反射膜14及支撑板11依次叠置在一起。本实施例中，所述显示屏1为LCD屏，所述LCD屏为现有技术中所采用的LCD显示屏幕，本申请不对LCD屏的具体结构进行详细描述。请参考图3所示，为本申请一实施例中电子设备100的部分结构示意图。本实施例中，所述壳体本体2包括屏幕背面部件21，所述支撑板11固定安装在所述壳体本体2的屏幕背面部件21上。例如，所述支撑板11通过螺钉固定安装在所述壳体本体2的屏幕背面部件21上。请参考图4，本实施例中，所述壳体本体2的屏幕背面部件21的材料为铝合金或镁合金，或塑胶材料。本实施例中，由于NFC信息是通过频谱中无线频率的电磁感应耦合方式传递，在通过电子设备100的NFC标签3实现和NFC外部设备进行通信的过程中为避免受到支撑板11吸收和干扰电磁波而导致NFC信号强度变弱或者无信号的情况，本实施例中，参考图3，所述支撑板11设置开孔111，所述屏幕背面部件21面向所述支撑板11的一面形成所述壳体本体2的内表面，所述NFC标签3贴附在所述壳体本体2的内表面上并面向所述支撑板11的开孔111。所述开孔111在所述内表面的正投影与所述NFC标签3重叠。如此，避免支撑板11对NFC标签3接收或发送的电磁波信号的干扰。本实施例中，开孔111在所述内表面的正投影与所述NFC标签重叠是指所述NFC标签3位于所述开孔111在壳体本体2的内表面的正投影之内，或者为开孔111在所述壳体本体2的内表面的正投影所形成的投影区域包括或覆盖贴附在所述壳体本体2的内表面上的NFC标签3。
本实施例中，所述支撑板11的材料包括铁、镍、铬、钛、铝、镁元素或其合金。在一实施例中，所述支撑板11为钢片，所述钢片为去磁处理的钢片。所述钢片的材料为不锈钢。本 实施例中，所述去磁处理是指将原来具有磁性的物体失去磁性的过程。在一实施例中，可以采用消磁器对所述支撑板11进行去磁处理。在另一实施例中，可以将支撑板11加热到预设温度(例如770摄氏度)对所述支撑板11进行去磁处理。在其他实施例中，可以通过交流电焊机产生交变磁场对所述支撑板11进行去磁处理。
本实施例中，支撑板11经去磁处理后，在支撑板11的预设位置处按照预设尺寸进行冲切形成所述开孔111。例如，参考图3，在支撑板11的右边按照预设尺寸进行冲切形成开孔111。为避免支撑板11对NFC标签3的影响，所述开孔111的预设尺寸大于所述NFC标签3的尺寸。在一实施例中，所述开孔111的预设尺寸包括所述开孔111的面积区域。例如，矩形状的开孔111的尺寸为开孔111的长与宽所确定的矩形面积区域。在另一实施例中，所述开孔111的预设尺寸包括所述开孔111的直径长度。例如，圆形状的开孔111的尺寸为开孔111的直径长度。在一实施例中，所述开孔111的预设尺寸可以为相对NFC标签3的周边侧外扩5mm形成的尺寸。在一实施例中，所述开孔111的形状与所述NFC标签3的形状相匹配。本实施例中，所述开孔111的形状与述NFC标签3的形状相匹配是指开孔111的外形所构成的图形与NFC标签3的外形所构成的图形相同或相似。在一实施例中，所述开孔11的形状根据NFC标签3的形状进行开孔设计。例如，若NFC标签3的形状为矩形，可以将开孔11的形状冲切成矩形。
需要说明的是，NFC标签3平整地贴附在壳体本体2上，如此避免NFC标签3起皱造成NFC外部设备在显示屏1的识别区域10识别NFC标签3时的电磁波信号的不稳定。为实现NFC标签3平整地贴附在壳体本体2上的目的，NFC标签3的材质可以为聚氯乙烯(Polyvinyl chloride,PVC)或聚对苯二甲酸乙二酯(polyethylene terephthalate，PET)。本实施例中，所述NFC标签3不做图案提示的外观油墨处理，例如NFC标签3不做印刷识别字符的图案提示的外观油墨处理，如此减少NFC标签3的设计成本。
请参考图5所示，为本申请另一实施例中显示屏1的结构示意图。所述显示屏1包括显示面板12。所述显示面板12安装在壳体本体2上。例如，所述显示面板12通过粘接的方式安装在壳体本体上。所述NFC标签3贴附在所述壳体本体2的内表面上并面向所述显示面板12。如此，保证了电子设备100在外观上的整洁度。本实施例中，所述显示屏1为OLED显示屏。
参考图6，将NFC外部设备放在所述NFC标签3的NFC识别区域后，电子设备100可以自动识别NFC外部设备并建立Wifi或蓝牙直连通道，实现电子设备100与NFC外部设备双方的信号连接。参考表一，所示为不同类型的手机与电子设备100进行NFC识别时的NFC识别范围的表格。其中，NFC识别范围是指NFC外部设备能够与电子设备100进行NFC连接的距离范围。例如在如下关系中，型号1手机与电子设备100进行NFC识别的NFC识别范围为0mm-7mm，型号2手机与电子设备100进行NFC识别的NFC识别范围为0mm-13mm。本实施例中，所述电子设备100可以为笔记本电脑、平板、显示屏等设备。所述NFC外部设备可以为手机、平板、穿戴式等设备。

步骤S703，根据连接请求获取NFC外部设备的设备信息并与所述NFC外部设备建立通信连接。
本实施例中，所述连接请求中携带有手机的设备信息。PC响应连接请求，从所述连接请求中获取手机的类型信息，并向手机发送回复信号。手机在接收到PC发送的回复信号后，手机与PC之间建立通信连接。例如，手机在接收到PC发送的回复信号后，手机与PC通过WiFi通信方式、蓝牙通信方式或NFC通信方式建立通信连接。需要说明的是，手机与PC通过WiFi通信方式、蓝牙通信方式或NFC通信方式建立通信连接的过程为现有技术，这里不再详细描述手机与PC通信连接过程建立的具体内容。步骤S704，根据所述NFC外部设备的设备信息，在所述显示屏1的第二区域显示所述NFC外部设备的屏幕内容。
参考图8C，PC获取手机的屏幕内容，根据手机的设备信息在所述显示屏1的第二区域82显示手机的屏幕内容。

步骤S901，从所述连接请求中提取所述NFC标签ID。
步骤S902，根据所述NFC标签ID获取NFC外部设备的设备信息。
需要说明的是，NFC外部设备的设备信息包括NFC外部设备的类型、NFC外部设备的型号、NFC外部设备的尺寸、NFC外部设备的生产厂商等信息，NFC外部设备的生产厂商在生产NFC外部设备(如手机)时，已将NFC外部设备的NFC标签ID与外部设备的型号及生产厂商等设备信息进行绑定。NFC外部设备的NFC标签ID与NFC外部设备的设备信息预 先存储在数据库中。电子设备100从所述连接请求中提取NFC外部设备的NFC标签ID后，根据所述NFC外部设备的NFC标签ID在数据库中查询，并确定出与所述NFC外部设备的NFC标签ID对应的设备信息。本实施例中，所述数据库包括所述NFC外部设备的NFC标签ID与所述NFC外部设备的设备信息的对应关系，其中不同的NFC外部设备的设备类型信息对应不同的NFC标签ID。在一实施例中，所述数据库存储在电子设备100的本地存储器中，电子设备100可以从本地存储器中获取数据库的数据。在另一实施例中，所述数据库存储在远端服务器中，电子设备100可以从远端服务器中获取数据库的数据。

步骤S1001，检测NFC外部设备的电磁波信号特征。
步骤S1002，根据所述电磁波信号特征确定NFC外部设备的设备信息。
本实施例中，由于不同的NFC外部设备的NFC标签中的NFC线圈存在差异(如线圈数量、尺寸存在差异)，因而NFC外部设备向电子设备100发送的电磁波信号特征(如电磁波信号强度)之间存在差异。电子设备100根据获取的电磁波信号特征通过查找数据库确定与获取的电磁波信号特征相对应的设备信息。在具体实施例中，所述数据库包括电磁波信号特征与所述NFC外部设备的设备信息，且不同的NFC外部设备的电磁波信号特征对应不同的设备信息。
例如，型号1手机、型号2手机两个NFC外部设备的NFC标签的线圈在数量及尺寸上存在差异，因而型号1手机发送给电子设备100的电磁波信号强度与型号2手机发送给电子设备100的电磁波信号强度不相同。若电子设备100检测出的电磁波信号强度与型号1手机对应，则确定NFC外部设备的设备信息为型号1手机。
