(SAW) Touch Screen Introduction:

Surface Acoustic Wave (SAW) Touch Screen is made of pure glass, and with extremely durable glass substrates, resulting in tough, reliable interfaces for demanding public access applications, with the 4mm & 6mm thickness Toughened Glass, the rigidity is several times that of ordinary glass, it is nearly impossible to be physically broken or "wear out", if the screen is broken, the fragments are safe with no sharp edges, and do not hurt people.

SAW Touch screen Benefits:

No coatings or overlays to wear, anti scratch, or tear.

High impact resistance.

Tempered heat or chemically strengthened glass.

Safe break pattern (tempered only).

Sizes from 6.4 inches to 29 inches.

Thicknesses: 3 mm, 4mm and 6 mm.

Anti glare glass & Metal enclosure mounting option.

Against dust, splashing liquids, and other contaminants.

4mm thickness was used Chemical Toughened glass to make of, can stand the impact of 520g metal ball drop from 1M high; Trial Standard No.:JC/T977-2005.

6mm thickness touch screens can stand the falling impact of a one- kg steel ball from one meter       high. Trial Standard No.: GB/T9963-1998 and 60950@IEC1999.(Option)

SAW Touch Screen Performance Overview:
Structure: Uses the glass surface, the surface does not have any coating, explosion-proof, anti- scratches, and its characteristics is fine;
Cable & Interface: Interface is square and double row:2x5?2x6 Pin?pin diameter:0.025 Inch?0.0635mm.
Error Margin & Precision: The standard error is less than 0.080 the inches (2.03 millimeters), the largest situations demonstrated the error is less than 1%?Resolution: 4096x4096.
Touch Point: Each square inch 1.00 million touch points (each square centimeter 15,000 to touch.
Touch Sensibility: Sensitive responds, regarding slight touching, the controller also can accurately respond, the reaction time is smaller than 10ms, touches dynamics to be less than 85 grams.
Visual Resolution Antiglare: 6:1 minimum(Option);.
Surface Hardness: Chemical toughened glass?Mohs' hardness rating of 7.(Standard:JC/T977-2005);.
