PRODUCT RANGE THRU-GLASS TOUCH SCREEN

The electronic controls effectively divide the screen into pixel size sensing cells, using microfine wires which are barely visible to the naked eye, on a powered display. These wires are connected to a controller board, and an oscillation frequency is established for each wire. Touching the glass causes a change in the frequency of the wires at that particular point, the position of which is identified and calculated by the controller. The front glass of the touch screen acts as a dielectric and enhances the capacitance of the touch screen.
