Zero-bezel SAW touch technology uses surface acoustic wave touch sensing placed on the bottom of a glass surface, allowing for a completely flat, bezel-free touch experience. It provides benefits like an elegant appearance, high sealability, easy maintenance on the flat glass surface, and accessibility across the entire visible screen area. The technology has been applied to displays ranging from 5.4 inches to 46 inches for uses in point of sale systems, digital signage, monitors, and more.

SAW (Surface Acoustic Wave) touch technology is one of the most age-old
touch technologies. It has been widely used since its birth because of
many significant advantages:
 Pure glass construction delivers the ultimate in image quality
 Reliable and stable, drift-free operation
 Continues to work even if scratched
 Finger, gloved hand, and soft stylus activation
 Fast touch response and accuracy
 Durable, easy to achieve high level anti-vandal
 Cost effective
GeneralTouch transfers the transducers and
reflect strips from the top to the bottom
surface of the glass to achieve Zero-bezel
SAW. Besides the above benefits, it also
features :
 Elegant appearance
 Easy integration into systems
 Easy maintenance
 High grade sealable
 All surface accessible
Applications
 Point of Sales
 Interactive Digital Signage
 Desktop touch monitor
 All-in-One PC
 Self-service terminal
 Hospitality
 Industrial control
 Gaming and amusement

The special
edge
The acoustic waves from the emitting
transducer pass over the edge of the
glass and brood over the anterior glass
surface. The acoustic waves proceed to
pass over the opposite edge of the glass
baseplate and to the corresponding
receiver transducer on the posterior.

Zero-bezel SAW touch
technology enables
integration much easier than
traditional SAW touch:
 Transducers and reflector
arrays are placed on the
backside, there is no need to
design a front frame to protect
them.
 Metal frame chassis optional,
which protects the transducers
and covers the reflector arrays,
making integration much easier

High sealable grade
The front surface is a whole sheet of
pure glass, it’s seamless. It can
prevent any liquid or dust invasion.
Easy maintenance
The reflector arrays and transducers are
located on the backside, any
contaminant on the front surface can’t
affect the touch performance and can
be wiped with rag easily.

The true flat surface without any
frame, all pixels from the first to
last in active area can be
approached easily.
It is very important for many
operations and gestures such as:
 Close a window
 Swipe from edge for app commands
