S450、触控微处理器判断所述特征码是否与当前交互红外智能笔的特征码匹配。在所述特征码与当前交互红外智能笔的特征码匹配时，执行S460，否则，返回执行S440。
典型的，如果红外智能笔与红外触控显示器是成套设备，那么红外智能笔与红外触控显示器应预先相互保存对方的特征码，例如产品序列号、机器码等。可选的，也可以由用户将红外智能笔的特征码录入红外触控显示器中，以使红外触控显示器确定当前交互的红外智能笔的特征码。
进一步的，触控微处理器可以将解码得到的特征码与预存的当前交互的红外智能笔的特征码进行匹配，以确认当前接收的红外信号是否为交互的红外智能笔发出的红外信号，这样可以消除其他红外信号对红外触控显示器造成的干 扰。
