The most common application is in mobile devices. The introduction of multi-touch in smartphones and tablets has fundamentally changed the way we interact with technology, making intuitive control via gestures such as swiping and pinching the norm.
Touchscreens are widely used in public spaces, such as at ATMs, ticket machines, and information kiosks. Their robustness and ease of use make them ideal for self-service applications that are used by a wide audience.
In industrial automation, touchscreens are used as Human-Machine Interfaces (HMIs). They enable operators to efficiently monitor and control machines and processes via an integrated and often robust display that can withstand harsh conditions.
Modern vehicles are equipped with infotainment systems that are operated via a central touchscreen. Drivers use these for navigation, climate control, and media. The integration increases ease of use and reduces the number of physical buttons on the dashboard.
This technology consists of two flexible layers that make contact when touched. A resistive screen responds to pressure and can be operated with any object, such as a finger, glove, or stylus. It is a cost-effective solution, but offers less clarity and does not typically support multi-touch.
Capacitive screens detect touch via the electrical properties of the human body. Projected Capacitive (PCAP) is the modern standard that supports multi-touch. This technology offers superior image quality, durability, and a highly responsive user experience.
Infrared touchscreens use a grid of infrared LEDs and photodetectors around the edges of the screen. A touch interrupts the beams, allowing the position to be detected. This technology is very durable because it does not require a physical layer over the display and can be operated with any object.
SAW technology uses ultrasonic waves that pass across the screen surface. When the screen is touched, part of the wave is absorbed, which is detected to determine the location. This method offers excellent image clarity but is sensitive to dirt on the screen.
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.
