Shenzhen 21.5 inch Optical touch screen   Our own Brand:  Professional manufactuer of the touch products in China Over 8 years.     Products Descriptioin:   Optical touch screen is composed by two optical image capture sensor and reflective strip. When objects contact with glass or transparent material, the optical effect of the touch point will be changed since the optical changing. It will generate relative distance between touch point and sensor, thus computing out of the touch position .
   Optical touch screen technology uses multiple optical sensors to detect the touch point, which registers the touch just before physical contact with the screen. This means that users can apply zero or light touch to the screen to initiate a response, and any input device, such as a finger, gloved finger, pen, or stylus will work.   Optical touch screen   > High clarity of image CCD technology
