Surface Light Wave”(SLW) is an innovative multi-touch technology. Based on the transmission property of Light, and integrated with the IR emitter of light wave, SLW can formulate a complicated and dense light net. When a signal receiving circuit receives the “broken” signal, the processor will analyze it and thus the touch points can be recognized. Therefore, SLW is a real above 10 points multi-touch technology, and can be extended to more touch points according to customers’ requirements. It is one of the most advanced multi-touch technology worldwide.

Compared to Resistive and Capacitive technologies, SLW technology provides superior image clarity, resolution, and higher light transmission. Because the panel is all glass, there are no layers that can be worn, giving this technology the highest durability factor and also the highest clarity.

RECOGNIZES TOUCH MATERIALS, THUS SUPPORTS MORE EXTENDED APPLICATIONS

The positioning method that IR touch screen is based on X Y axis scanning. This way the processor only can obtain the coordinates, but with Surface Light Wave, the processor can describe the shape of an object with the coordinates in the center. This is a significant benefit that many other technology cannot compare with. For example, the screen will give you different results when you use a finger and a palm to touch the it.

Available from 32″ to 84″
