  目前几种触摸屏的原理
  触摸屏的种类
  1、红外线式触摸屏
  红外线触摸屏原理很简单,只是在显示器上加上光点距架框,无需在屏幕表面加上涂层或接驳控制器。光点距架框的四边排列了红外线发射管及接收管,在屏幕表面形成一个红外线网。用户以手指触摸屏幕某一点,便会挡住经过该位置的横竖两条红外线,计算机便可即时算出触摸点位置。红外触摸屏不受电流、电压和静电干扰,适宜某些恶劣的环境条件。其主要优点是价格低廉、安装方便、不需要卡或其它任何控制器,可以用在各档次的计算机上。不过,由于只是在普通屏幕增加了框架,在使用过程中架框四周的红外线发射管及接收管很容易损坏,且分辨率较低。
  2、电容式触摸屏
  电容式触摸屏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。
  3、电阻技术触摸屏
  触摸屏的屏体部分是一块与显示器表面非常配合的多层复合薄膜,由一层玻璃或有机玻璃作为基层,表面涂有一层透明的导电层(OTI,氧化铟),上面再盖有一层外表面硬化处理、光滑防刮的塑料层,它的内表面也涂有一层OTI,在两层导电层之间有许多细小(小于千分之一英寸)的透明隔离点把它们隔开绝缘。当手指接触屏幕,两层OTI导电层出现一个接触点,因其中一面导电层接通Y轴方向的5V均匀电压场,使得侦测层的电压由零变为非零,控制器侦测到这个接通后,进行A/D转换,并将得到的电压值与5V相比,即可得触摸点的Y轴坐标,同理得出X轴的坐标,这就是电阻技术触摸屏共同的最基本原理。电阻屏根据引出线数多少,分为四线、五线等多线电阻触摸屏。五线电阻触摸屏的A面是导电玻璃而不是导电涂覆层,导电玻璃的工艺使其的寿命得到极大的提高,并且可以提高透光率。
  4、表面声波触摸屏
  ————————————————————————————————
  你可以分析一下
  MINIPLAYER触摸键旁边没有框架
  所以不是红外线的
  ——————————————————————————
  你试着放块热乎的红烧肉,或者水杯等等
  它也不动
  所以不是温度
  ————————————————————————
  另外触摸键表面并没有玻璃
  所以也不是电容式
  ————————————————————
  表面超声波的过于高端
  也不是
  ————————————————
  你试着用测电笔接上触摸键的两端
  会发现它是导电的
  所以实际上
  魅族用的是电阻式
  这点官方论坛里也有提到

回答2:

那你还想用什么?!

回答3:

有温度感应的,相当耐用。

回答4:

是红外线感应的,并非温度

回答5:

有温度的
