显示设备可以是电视机，显示设备需要获取无线网络的密码、路由器的名称等配置信息，由显示设备根据配置信息及显示设备自身的IP地址信息生成一二维码图片，该二维码图片存储于显示设备中。
步骤S102，在接收到显示指令时，所述显示设备根据所述显示指令显示所述二维码图片；
本实施例中，当显示设备已存储有二维码图片时，可通过特定的显示指令调出该二维码图片。如当用户通过遥控器的特定按键或者显示设备面板上特定的按键触发上述特定的显示指令时，显示设备调出该二维码图片并显示在屏幕上，以供用户使用终端进行扫描。
本实施例中，显示设备可通过有线或者无线的方式连接到局域网中。
其中，如果显示设备没有连接到局域网，则显示设备建立WIFI Direct网络，然后根据WIFI Direct网络信息和显示设备自身的IP地址，生成二维码图片。
步骤S103，所述终端扫描所述二维码图片，解析所述二维码图片，得到所述配置信息及显示设备的IP地址信息；
本实施例中，终端可为手机或平板电脑，以手机为例，用户可以将手机切换至二维码扫描界面，来扫描显示设备上的二维码图片，手机成功扫描该二维码图片后，对二维码图片进行解析，解析后得到局域网的配置信息及显示设备的IP地址信息，供后续手机连接局域网及显示设备所用。
在本实施例中，如果是非家庭成员使用手机来连接显示设备时，如有客人来访时，希望将客人的手机上的文件在大屏幕的显示设备上进行显示，这时，经过用户的允许，可以使用遥控器或者点击显示设备面板上特定的按键来点出该二维码图片，客人使用自己的手机扫描显示设备上的二维码图片，不需要用户将局域网的密码告知客人，保证局域网的密码不外泄，隐私得到较好的保护。
步骤S104，所述终端根据所述配置信息连接所述无线网络，根据所述IP地址信息连接所述显示设备。
本实施例中，手机可以根据配置信息中的局域网的密码、路由器的名称等信息无线连接到局域网中。然后，手机再根据解析出的显示设备的IP地址信息，与显示设备直接建立应用层的逻辑连接，连接后，手机可以对显示设备进行智能操控或在显示设备上共享媒体内容等操作。
本实施例中，手机连接显示设备的操作只需要用户调出二维码图片，以及用户使用手机扫描二维码图片即可将其与显示设备建立快速连接，省去了如输入密码，搜索设备等繁琐的流程，使手机与显示设备连接更加自动化和智能化。
与现有技术相比，本实施例显示设备基于无线网络的配置信息及显示设备的IP地址信息生成二维码图片并存储，用户可以通过特定的按键将二维码图片调出来并显示，然后可以使用终端如手机等扫描该二维码图片，由于二维码图片是根据局域网的配置信息及显示设备的IP地址信息而生成的，因此，终端可以通过配置信息来连接局域网，通过IP地址信息连接显示设备，完成终端与显示设备的快速连接，简化操作步骤；另外，由于不需要告知终端持有者局域网的密码信息，能够保证局域网的密码不外泄，隐私得到较好的保护。
