A resistive touch screen is a clear overlay which uses physical pressure to detect touch input. It consists of two layers, a flexible outer layer and glass inner layer, separated by an air gap which is maintained by micro dots. The layer configuration used by this technology can accommodate only single touch events, and reduces the transmittance, or brightness, of the display underneath by 20% to 30%. However, resistive touch overlays are often more light weight than their capacitive counterparts, offer higher precision, and can be activated with ordinary implements, including gloved hands. A resistive touch panel will typically be less durable than a capacitive version, with a scratch hardness value of only 3 and lifespan rating of 1 million touches. However, the versatility of this technology and low cost has made it attractive to industrial applications that require advanced input.
