声音特征信号数据库还用于根据接收到的声音特征信号和身体触控类型，更新声音特征信号与身体触控类型之间的对应关系。这样声音特征信号数据库不但可以存储声音特征信号与身体触控类型之间的对应关系，还可以根据需要更新声音特征信号与身体触控类型之间的对应关系，并根据需要添加新的声音特征信号与身体触控类型之间的对应关系。
进一步地，如图2所示，中央处理器20包括：

特征提取模块23，用于根据信号处理模块22所获取的声音参数对声音振动信号进行特征提取，获取声音特征信号；
比对模块24，用于将所获取的声音特征信号与声音特征信号数据库中的数据进行比对，确定与声音特征信号对应的身体触控类型。
进一步地，触控显示设备还包括：触发事件数据库，用于存储触控点坐标位置和身体触控类型与触发事件之间的对应关系，比如额头触控+触控点位置坐标对应对触控点处的图标实现确定功能、下巴触控+触控点位置坐标对应对触控点处的图标实现取消功能、鼻尖触控+触控点位置坐标对应对触控点处的图标实现双击功能、脚趾触控+触控点位置坐标对应对触控点处的画面实现放大功能等等。
控制芯片30具体用于将接收到的指令信号中包含的身体触控类型和触控点位置坐标与触发事件数据库中的信息进行比对，确定与身体触控类型和触控点位置坐标对应的影像数据和驱动信号，比如在中央处理器20确定身体触控类型为额头触控时，控制芯片30将与对触控点处图标实现确定功能对应的影像数据和驱动信号发送至图像处理器，进而驱动显示屏显示与确定功能对应的画面；在中央处理器20确定身体触控类型为下巴触控时，控制芯片30将与对触控点处图标实现取消功能对应的影像数据和驱动信号发送至图像处理器，进而驱动显示屏显示与取消功能对应的画面；在中央处理器20确定身体触控类型为鼻尖触控时，控制芯片30将与对触控点处图标实现双击功能对应的影像数据和驱动信号发送至图像处理器，进而驱动显示屏显示与双击功能对应的画面；在中央处理器20确定身体触控类型为脚趾触控时，控制芯片30将与对触控点处画面实现放大功能对应的影像数据和驱动信号发送至图像处理器，进而驱动显示屏显示与放大功能对应的画面。

进一步地，如图3所示，触控显示设备还包括：数据存储单元70，与控制芯片30连接，用于存储控制芯片30接收到的当前帧的指令信号，这样通过数据存储单元70可以记录历史数据。
进一步地，触控显示设备还包括：缓存单元80，与控制芯片30连接， 用于对控制芯片30接收到的下一帧的指令信号进行缓存。这样在下一帧时，控制芯片30可以直接利用缓存在缓存单元80中的指令信号生成对应的影像数据和驱动信号，能够加快身体部位识别以及触控触发的速度。
其中，缓存单元80、数据存储单元70和图像处理器40可以通过总线与控制芯片30连接。
