If there’s one thing we are used to when we’re operating anything, it’s knobs and dials. We enjoy their familiar tactile experience when we control settings, like volume or menus. Somehow, a 100% touchscreen experience often isn’t enough and there is a real and very human satisfaction in the physical feedback when we ‘touch that dial’.
Certainly, it’s something our industrial, automotive or commercial customers have been asking for. So, we’ve created a way to integrate this experience into our touch displays without requiring any holes drilled or modifications to the display surface. Our PCAP solution simply glues the knob/dial to the display and achieves this by using the capacitive touch technology which is inherent to PCAP screens. The result is a look that is modern and sleek, maintains the integrity of the screen and still gives the user that very real feeling of control.
Beyond the aesthetics
Yes, it looks great, but we’ve also made sure that it is highly functional and high performing in various applications. For example, infotainment and climate control systems, industrial control panels and medical devices.
Traditional rotary encoders often require drilling or holes in the display surface. Ours doesn’t disrupt the protective glass layer of the touchscreen, maintaining the screen’s IP-rated sealing, making it ideal for rugged environments or applications where waterproofing is critical.
The knob is designed to work harmoniously with the PCAP sensors for precise rotational control over volume, brightness or other parameters without compromising the touch functionality of the display.
Complex algorithms distinguish between accidental and intentional touches. So, the rest of the screen remains fully responsive to touch gestures like swipes and pinches.
Capacitive technology means it can be placed virtually anywhere on the touchscreen surface offering flexibility in design. Users can adjust its location, making it customizable to their specific interface or application needs.

In the industrial world, the capacitive touchscreen can be a sensitive soul. It performs beautifully under ideal conditions, but this is a luxury most industries can’t afford.
There’s a word we really like here at Avnet Displays: simplification. Our engineers ask themselves, “how can we make this easier for our customers and their end-users?” and “what will it take to make using this display as simple as possible?”
We believe in ease and effectiveness, working with the user to create designs which work. This is a perfect example of how traditional physical control and modern touchscreen technology can simplify design, reduce installation complexity and enhance user interaction. And still maintain the durability and aesthetics for applications required across industrial or consumer applications.
