A:现在,智能手机、平板电脑、数码相机、银行柜员机等电子设备上,触摸屏的应用越来越广。触摸屏是通过传感器来感知物体在屏上的运动,根据传感器的不同,通常可以分为电容、电阻、红外线、表面声波等几种类型。现在日常使用的数码移动设备,如手机等,越来越多地采用电容式触摸屏。这种屏界面友好、使用方便、功能强大,但是一到冬季,戴上手套就无法使用了,这是它的一个缺点。电容式触摸屏是一块多层复合玻璃,在夹层中涂有具有一定导电性且透明的薄膜材料,如氧化铟锡(ITO)。由于人体也有一定的导电性,当手指触碰到这种屏时,手指和ITO薄膜就会形
A: Nowadays, the applications of touch screens are getting wider and wider on electronic devices such as smart phones, tablet computers, digital cameras and bank teller machines. Touch screen through the sensor to sense the movement of objects on the screen, according to the different sensors, usually can be divided into capacitors, resistors, infrared, surface acoustic waves and several other types. Nowadays the daily use of digital mobile devices, such as cell phones, more and more adopt capacitive touch screen. This screen-friendly interface, easy to use, powerful, but in winter, wearing gloves can not be used, and this is one of its drawbacks. Capacitive touch screen is a multi-layer composite glass, the interlayer coated with a certain conductivity and transparent film material, such as indium tin oxide (ITO). As the human body also has some electrical conductivity, when the finger touches this screen, the finger and the ITO film will be shaped
