SURFACE CAPACITIVE SCREENS
DawarTouch Surface Capacitive Touch Screens provide superior optical performance with extreme endurance and reliability over long periods with extensive use. They are a preferred and excellent choice for highly demanding medical, public and industrial applications, such as Point-of-Sale, kiosks, ATMs, gaming machines and industrial controls.
All-glass construction with a transparent conductive ITO coating evenly distributed over both sides of the glass provides superior optical qualities. An electrode pattern is precisely printed around the perimeter of the glass to accurately generate an alternating current over the conductive layer. The touch of a conductive probe draws the current to the specific point of contact. The controller then calculates the location of the touch by evaluating the flow of current from each corner. This flow of current is proportional to the distance to the touch.
