From the technical principle to distinguish the touch screen, can be divided into five basic categories: vector pressure sensing technology touch screen, resistive technology touch screen, capacitive technology touch screen, infrared technology touch screen, surface acoustic technology touch screen. One of the vector pressure sensing technology touch screen has exited the historical stage; Infrared technology tactus collaborative text cheap, sed exterius arca fragilis, proni ad lucem intercessiones, curvam superficiem distortione; Capacitive tactus tactus screen consilio est rationabile, sed eius imago distortio problema difficile solvitur fundamentaliter; Resistentia technology tactus screen positus est accurate, sed pretium est satis excelsum {{I}}
And is afraid of scraping easily damaged, surface acoustic touch screen to solve the previous touch screen of various defects, clear not easy to be damaged, suitable for various occasions, the disadvantage is that the screen surface if there is water droplets and dust will make the touch screen becomes dull, even do not work. According to the working principle of the touchscreen and the media that transmits the information, the touch screen is divided into four kinds, which are resistive type, Capacitive inductionive genus, infrared type et superficiem acousticus fluctus type respectively {{I}} quisque tactus screen habet suum commoda et incommoda, quod situ quodam tactus screen technology {{}}
