5 Wire resistive touch screen follows the similar format(4 wire touch panel), also using two layers to determine the precise point of contact. However, only one of these layers contains electrodes. In a typical 5 wire resistive touch screen panel configuration, the bottom layer contains electrodes on each of the four corners. These electrodes are designed to emit a small but noticeable amount of voltage. The other layer, the top layer, is designed to measure the voltage of the bottom layer. When you touch the surface, it presses the two layers together, similar to how the 4-wire resistive setup works; thus, allowing the device to determine when and where the touch occurred(so 5wire touch screen working life is longer than 4 wire touch screen, but the linearity is a bit worse than 4 wire resistive touchscreen).

Resistive touch panel is used in restaurants, factories and hospitals due to its high tolerance for liquids and contaminants. The main benefit of resistive touch technology is its low cost. Additionally, as only sufficient pressure is necessary for the touch to be sensed, they may be used with gloves on, or by using anything rigid as a finger substitute. Disadvantages include the need to press down, and a risk of damage by sharp objects. Resistive touch screen panel also suffer from poorer contrast, due to having additional reflections from the layers of material placed over the screen.
