Recently, the surface acoustic wave touch screen product has been successfully developed by DWIN Technology. It has high reliability characteristics such as riot resistance, corrosion resistance, and anti-electromagnetic interference. It can be applied to DGUS smart screens or embedded system screens such as Linux, Android, and Windows which is suitable for sales service terminals such as shopping malls, bank self-service terminals, interactive game machines and industrial control fields. Users are welcome to contact DWIN sales personnel to obtain samples for trial use.
Features:
1) The surface acoustic wave touch screen adopts the ultrasonic positioning technology on the glass surface to realize touch sensing, and has excellent anti-electromagnetic interference ability.
2)The touch screen glass can be made of 4mm to 10mm physical toughened glass or other special glass, which has 98% high light transmittance, anti-riot, corrosion resistance, scratch resistance and other characteristics.
3)High-density touch point distribution, more than 10,000 touch points per square inch, no touch drift, and automatic correction.
4)Support finger, soft pen, glove touch, and the life span can reach more than 50 million single-point touches, which is suitable for high-intensity and high-frequency touch requirements.
5)The touch screen can be customized in various sizes such as 21.5~100 inches.
