Capacitive Vs. Resistive Touchscreens
A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. Although this technology was invented in the UK in 1965 it only gathered commercial pace with the spread of computers in the 80s and has witnessed the greatest boost in momentum in recent years from the mobile phone sector.

There are almost a dozen different technologies for touchscreens but by far the 2 most common are resistive and capacitive.
Resistive touch screens respond to pressure and have been perhaps the most common implementation of touch screen technology due to its low cost. A resistive touchscreen panel is made up of electrically conductive layers. When the panel is touched the layers come into contact at that point which can be accurately detected and sent to the controller for processing. Because the touch is sensitive to applied pressure the touch source can be any object, either a human finger (including gloved) or any other inanimate pointer. One disadvantage however of resistive technology is its vulnerability of being damaged by sharp objects. Although uncommon and unknown by many resistive touch screens can and do support multi-touch. Although multi-touch is rarely a useful feature for most business processes, if required it does not limit your choice of technology. In fact we have devices that support 4 independent touch points on a resistive screen.
Capacitive touch screens involve an insulating outer layer (normally glass) coated with a transparent conductive metal compound. The technology works by detecting changes in electrical conductivity across that layer. As the human body is also an electrical conductor, touching the surface of the screen results in interference of the screen’s electrostatic field, the location of which can be detected and sent to the controller for processing. Because the technology relies upon electrical interference from a conductive source capacitive touchscreens do not work through most gloves as they are electrically insulating.
Likewise an ordinary stylus or other object cannot be used. Yes it has rapidly become the common touch screen technology found in virtually all touchscreen consumer mobile devices today. Capacitive screens have become loved for use of ‘gestures’ and ‘multi-touch’. Whilst neither is exclusive to this type of screen it could be fairly said that these motions are easier and a little more natural when less pressure need be applied. However, we rarely encounter a use for these types of touch-motions under business conditions.
