Digital Resistive (Transparent Membrane Switch)
This touch screen is sometimes referred to as the X-Y matrix touch screen. Digital resistive touch screens are as easy to interface with a controller as a conventional matrix keyboard and popular when finger-sized touch zones are required.
To produce digital resistive touch screens, the ITO coating is etched away (or selectively applied) to form rows on one layer and columns on the opposite layer (Figure 1). When assembled, the rows and columns form a matrix of switches. The location of each switch is permanent, and the size cannot change. The resolution of the touch screen depends solely on the number of rows and columns.
