A resistive touchscreen panel comprises a number of layers, the most important of which are 2 thin, transparent electrically-resistive layers separated by a thin space. These layers deal with each other with a thin space between. The leading screen (the screen that comes incontact) has a covering on the underside surface area of the screen. Just underneath it is a similar resistive layer on top of its substrate. One layer has conductive connection A voltage is applied to one layer, and picked up by the other. When an object, such as a fingertip or stylus pointer, presses down onto the outer membrane keypad manufacturers surface area, the two layers touch to become linked at that point: The panel then behaves as a pair of voltage dividers, one axis at a time. By quickly switching in between each layer, the position of a pressure on the screen can be read. We see use of Resistive touch in dining establishments, factories and medical facilities due to its high resistance to liquids and impurities. A major advantage of resistive touch technology is its low cost. In addition, as only enough pressure is needed for the touch to be sensed, they might be used with gloves on, or by utilizing anything rigid as a finger/stylus substitute. Downsides consist of the need to push down, and a threat of damage by sharp items. Resistive touch screens also experience poorer contrast. Due to having extra reflections from the extra layers of product (that the air space separates) that you place over the screen.
