1、三大教学触控一体机价格比值 目前市场上主流教学触控一体机主要分为三大类：电阻触摸一体机 电容触摸一体机 红外触摸一体机，它们的价格也相差甚远电阻教学触控一体机： 电阻教学触控一体机屏和 控制系统 都比较便宜，反应灵敏度也很好，对外界完全隔离的工作环境，不怕灰尘和水汽，能适应各种恶劣的环境。它可以用任何物体来触摸,稳定性能较好。电阻式的触摸屏由于需要一定的压力，时间长了容易造成表面材料的磨损，影响产品的正常使用寿命价格低廉。 电容教学触控一体机： 电容式教学触控一体机的构造主要是在玻璃屏幕上镀一层透明的薄膜体层，再在导体层外加上一块保护玻璃，双玻璃设计能彻底保护导体层及 感应器这层玻璃显然是不导

2、电的，直流导电是不行了，改用高频交流信号，靠人的手指头（隔着薄玻璃）与工作面形成的耦合电容来吸走一个交流电流，这就是电容屏“电容”名字的由来：靠2014年中考冲刺综合复习指导北京地区试题 广东地区试题 江苏地区试题耦合电容来工作不稳定。耦合电容的方式直接受温度、湿度、手指湿润程度、人体体重、地面干燥程度影响，受外界大面积物体的干扰也非常大，带来了不稳定的结果。在大尺寸方面价格昂贵！ 英文全译；I just want a person to walk quietly, slowly, leisurely, looking for their own piece of silent in the

3、hustle and bustle.
