The most common application of Projected Capacitive (PCAP) touchscreens. These devices require the high accuracy, clarity and multi-touch functionality that capacitive technology provides for a smooth and intuitive user experience, from swiping to zooming.
For public terminals such as kiosks and automated teller machines (ATMs), more durable technologies such as resistive, SAW or infrared displays are often used. These must withstand heavy use and environmental conditions and provide reliable functionality for a wide audience.
In industrial or medical environments, resistive touchscreens are popular because they can be operated with gloves or a stylus. They are less susceptible to interference from liquids or dust, which is essential for reliability in demanding work environments.
POS systems in the retail and hospitality industries often use resistive touch screens. They are cost-effective, durable and can be operated quickly and reliably with a finger, pen or card, making them ideal for quick transactions in busy environments.
This type of screen consists of two flexible, conductive layers that contact by pressure to register the touch location. They are inexpensive and work with any object, such as a pen or gloved finger. Disadvantages include lower sensitivity, reduced image clarity and lack of multi-touch support.
The standard for modern consumer electronics. A grid of electrodes detects the disruption in the electromagnetic field caused by a finger. This technology offers very high precision, excellent image quality and enables complex multi-touch gestures such as 'pinch-to-zoom.
SAW technology uses ultrasonic waves moving across the screen surface. A touch absorbs part of this wave, detecting the location. These screens offer superior image clarity and durability, but are vulnerable to contamination from water, dust or dirt.
A grid of infrared LEDs and sensors along the edges creates an invisible light grid. When an object breaches this grid, its position is calculated. This technology is very durable and supports multi-touch, but can be sensitive to accidental activation and bright ambient light.
At Dytos, we understand that each industry has specific requirements for touch solutions. That's why we offer a wide range of products and services designed to meet these diverse needs.
