A resistive touchscreen consists of two transparent conducting layers each with densely packed sensors. These layers are separated by an air gap, and react when pressure is applied to the screen. As the outer layer is pressed against the layer beneath it a connection is made which registers the input. resistive touch screens offer stability, usability, and can be operated with a finger, stylus or any other objects.
Surface Capacitive Touch
A capacitive touchscreen’s front surface sensor works by detecting the conductive properties from the skin on your finger and objects like a conductive stylus or glove. The glass surface of a capacitive touchscreen makes it more durable, easier to clean, scratch resistant, and offers exceptional picture quality over a standard resistive touchscreen. Additionally, touch function isn’t affected by dirt, finger print smudges or even minor cracks in the glass surface. Due to these attributes, capacitive touchscreens are more responsive and yield a clearer viewing experience over resistive touch.
Projective Capacitive (PCAP)
This technology works by using a conductive grid that recognizes changes in its electromagnetic field caused by touch from a finger, stylus or gloved hand. PCAP is the most widely used touch technology today, and offers more responsiveness, allowing for added finger operations such as swiping, pinching, zooming, rotating, and even responding to certain gestures. Thick glass overlays or vandal-resistant protective layers can be installed directly over the PCAP touch sensitive surface without interfering with touch functionality. Projective capacitive touch advantages include: outdoor operability in rain, snow, ice and dust; multi-touch gesturing; activation by gloved hand or stylus; functionality even if glass is scratched or broken.
ArmorTouch (Glass-on-Film Resistive Touch)
ArmorTouch touchscreen is a durable Glass-Film-Glass resistive touchscreen technology with a tough glass surface that is scratch, abrasion, water, and chemical resistant. The pressure activated resistive touchscreen can be activated by finger, glove, or stylus and will continue to function with contaminants such as oil, grease, dirt, or water on the screen. This touchscreen’s construction allows it to be used across a range of harsh operating environments including rugged, outdoor and unattended kiosk applications.
