CJTouch is leading Touch Screen Solution manufacturer in China. Today, CJTouch is a leading global supplier of touch-enabled technology, products and industry solutions.We can offer SAW touch screen,Infrared touch screen,Resisitive touch screen and Projected Capacitive touch screen.Surface Acoustic Wave (SAW) touch screen technology is based on sending acoustic waves across a clear glass panel with a series of transducers and reflectors. When a finger touches the screen, the waves are absorbed, causing a touch event to be detected at that point.
Like infrared technology, the panel is all glass, so there are no layers that can be worn, or damaged over time. This makes SAW touch screen technology highly durable and suitable for applications where high clarity is desired.It features unrivaled accuracy, reliability, sensitive and drift-free performance, can be touched by fingerer, glove, leather or stylus pen.
SAW touch screen technology is recommended for public information kiosks and other high traffic indoor environments.
Benefits of SAW Touch Screen Technology
Limitations of SAW Touch Screen Technology
Must be touched by finger, gloved hand, or soft-tip stylus. Something hard like a pen, credit card or finger nail won't work
Can be affected by large amounts of dirt, dust, and / or water in the environment.
