Resistive screens are pressure sensitive and can be touched with a finger, stylus or just about any pointed object. They use two active layers: a flexible plastic layer on top of a rigid plastic or glass layer, with insulated spacers in between. The layers are coated with indium tin oxide, and different voltages are applied across the coatings, typically alternating between the layers. When touched, the front layer picks up the voltage from the back, and the back layer picks up the voltage from the front, enabling the controller to determine the X-Y location.

Although the least expensive, the resistive method blocks up to 45% of the light from the CRT or LCD screen due to the multiple layers and coatings.
