What is a Resistive Touchscreen?

Like capacitive touchscreens, resistive touchscreens are a form of Human Machine Interface (HMI) technology, commonly used to control equipment in a range of industrial settings. Offering an intuitive interface for machine operators, touchscreen systems are a ubiquitous part of manufacturing facilities, medical equipment and automation systems. Resistive touchscreens use the physical movement of the touch surface to establish where the user is touching the screen.


How Do Resistive Touchscreens Work?

Resistive touchscreen panels consist of top and bottom transparent sheets coated with a conducting material and spaced a small distance apart. A uniform resistance value is applied to each sheet and as the top sheet gets pressed and contacts the bottom sheet electricity gets conducted and the location of the conducted point is detected by the controller.


Where are Resistive Touchscreens Used?

Because they can be used while wearing gloves, factory automation and medical equipment often utilize resistive touchscreens for HMI, but resistive touchscreens are also being deployed in a wide range of industrial applications where their more tactile interface is prefered.
