Zero-bezel SAW

The Working Principle of iSurface Touch Technology



The Zero-bezel SAW touch technology is based on the proven Surface Acoustic Wave (SAW) technology. All the reflection stripes are moved to the back surface of the touchscreen. The areas where the transducers are located must flush with the front, rear and side surfaces of the glass panel so that the surfaces are continuous and even. The back surface of the glass panel where the arrays of reflectors are situated should have an opaque coating to keep the transducers and the cables from being visible at the front. The completely flat screen makes the surface perfect and easy to be integrated into monitors and other devices.


Though different from the conventional SAW technology, the iSurface touch technology delivers the same superior touch performance. With a completely flat screen, the iSurface has achieved esthetic appearance and top-notch functionality. GeneralTouch iSurface features quick and accurate responses without any drift-off. Since reflection strips are located on the back surface, it is easier to integrate iSurface touchscreen into your total solutions.
