Optical Imaing Ccd 32 Inch Multi Infrared Touch Screen For 32’’ Lcd / Led / Plasma

Optical imaing CCD 32 inch multi infrared touch screen for 32’’ LCD / LED / PLASMA

 

 

 

Hitouch  Optical Imaging CCD 32’’ Multi Touch Screen Overlay is made with optical imaging technology. Optical imaging is a new technology which is used in touch screen area, it take advantages of 2 CCD lens which locate on the top-left and top-right of the touch screen to detect the touch, besides, the others 3 sides reflective strips are a must to make the detection available. The work principle is very simple, but the touch screen works very well, thus it becomes very popular. Besides, more than two points touch is available if the techinian can arrange the more CCD lens inside of the touch screen and organize the system well.

 

Optical Imaging touch screen features:
1. Win7 multi touch
2. 8ms response speed
3. Less than or equal to 1.5mm touch accuracy
4. 32767*32767 touch resolution
5. Good structure on the frame
6. USB Powered
