Tech Global's Dynamic-touch Surface Capacitive Touch Screens are an all-glass construction with greater than 9H Surface hardness able to withstand over 300 million touches. A transparent conductive ITO coating is evenly distributed over both sides of a glass substrate. An electrode pattern is precisely printed around the perimeter of the glass to accurately generate an alternating current over the top 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. The ITO coating on the back of the glass functions as a shield to protect against ESD and outside interference. With no mechanical movement and a 9H surface hard coat, a capacitive touch screen can withstand 300 million touches.
