How Do Touchscreens Work?

There are many different types of touchscreen technology, such as resistive, capacitive, infrared, and surface acoustic wave. Here, we delve into some of the most popular touch technologies utilized by HeyKD, including infrared and projected capacitive touch displays.


Infrared technology uses a series of LED lights and sensors arranged in a grid-like structure around the edge of a touchscreen device. These lights constantly emit and project light in a uniform pattern. When you touch the screen, this pattern is disturbed, and the device identifies where this disturbance occurred, registering the precise point of contact. The beauty of infrared technology is that the user doesn’t even need to make contact with the screen itself, only needing to break the pattern for the device to register the touch.

One of HeyKD’s most popular technologies is the Infrared Interactive Touch Frame, which can transform any screen or surface into an interactive display. These lightweight touch overlays are robust, easy to install, and use USB HID plug-and-play functionality to make any existing screen interactive in no time.

HeyKD also offers Interactive Mirrorvision Screens, utilizing infrared technology to create a unique display ideal for retail applications. Users can interact with content and create a personalized shopping experience. Other infrared technologies include Interactive Transparent DisplaysSwitchable Glass Screens, and Digital Glass Touch Screens.

Projected Capacitive

Projected Capacitive touchscreens are designed to work with the touch of your finger (e.g., smartphones and fingerprint security). Unlike infrared, which uses a grid-like array of LEDs and sensors, projected capacitive relies on a uniform electrostatic current.

Capacitive displays, or PCAP displays, consist of a thin layer of glass on top of an electrostatic grid of millions of minuscule electronic wires. When you touch the screen, you complete the electrical circuit—so the display registers your touch before relaying this information over to your device’s interface.

HeyKD offers a number of exciting PCAP technologies, including Interactive Touch Foils and Interactive Projection Foils, that use through-glass technology to transform any glass surface into a touch screen. These Touch Foils are perfect for creating store window displays that can be used 24/7, maximizing the potential for advertising and engagement even outside store hours. Other PCAP technologies include the Interactive Touch TablePCAP Touch Overlays, and Interactive Kiosks.

What is a Touchscreen Digitizer?

The digitizer is a thin layer of glass placed over a device’s liquid-crystal display (LCD) which essentially converts analogue touch commands into digital signals. In other words, it turns a single touch of a finger into a digital command that your device can use. These digitizers are present in technologies using projected capacitive touch.

How Long Do Touchscreens Work?

The lifespan of a touchscreen depends on its type. Infrared and capacitive touchscreens are notoriously long-lasting, so you can expect both to last well over 5 years (with many lasting longer than 10 years, provided they’re looked after and not subject to particularly harsh conditions).

What is an Interactive Kiosk?

Interactive Kiosks enable businesses to leverage touchscreen-based self-service functionality to help more consumers, more easily, using fewer resources. HeyKD’s Interactive Kiosks come in many shapes and sizes, catering for both indoor and outdoor applications. They can create bespoke kiosk solutions to suit a wide range of applications.

From the common freestanding poster systems often seen in fast food restaurants to custom designed Interactive Transparent Kiosks for POS displays, HeyKD can provide a solution that’s designed with your application in mind.

How Can You Use Interactive Kiosks?

Interactive Kiosks can be used for various purposes, including:

  • Providing customer help services
  • Wayfinding—helping people navigate large shopping malls or conference centers
  • Advertising

Of course, the above list is far from exhaustive. Interactive Kiosks can be used anywhere you wish to provide on-demand digital information or services at the touch of a finger.

What Are the Advantages of Interactive Kiosks?

Interactive Kiosks offer numerous benefits. They allow you to:

  • Reach a larger and more diverse audience more easily
  • Increase your internal efficiency
  • Improve your user experience

Customers often prefer to be self-sufficient rather than feel like they’re bothering members of staff. Interactive Kiosks allow users to browse at their leisure, making them feel more comfortable with shopping in store and inevitably leaving them feeling more satisfied with their experience.

What Are Interactive Mirrors?

Interactive Mirrors combine the wow factor of a standard mirror screen display with the flexibility of a touch screen. HeyKD’s technology combines the stunning visuals of their Professional Mirrorvision Display with the infrared touch capabilities of their popular Touch Frame. These solutions are ideal in retail applications, where Interactive Mirrors can be installed in fitting rooms, providing a great upselling opportunity at a key point in the customer journey, while also providing the user with an experience that’s completely unique to them.

How Do You Clean a Touchscreen?

Given that touchscreens consist of intricate, often expensive technology, you should steer clear of simply giving them a scrub with a wet cloth. Instead, invest in a microfibre cloth, put on a white background display (this will help you spot any dirt), and wipe away.


Touchscreen technology is a game-changer in the retail industry, and HeyKD is leading the way with its innovative kiosk solutions. Whether you’re a potential client, an investor, or an industry professional, understanding the workings of this technology and its applications can provide valuable insights into the future of retail.
