Operation and Technology of Infrared Touchscreens

An infrared (IR) touch screen detects touch by interrupting a grid of invisible infrared rays. Integrated into the edge of the screen are LEDs and sensors that create a network of horizontal and vertical light beams. When a finger, stylus or other object touches the screen, a beam is blocked. The sensors record the exact location of this interruption and convert it into a coordinate. This technology requires no pressure or conductive material, making it highly versatile and durable for a variety of applications.

Kiosks and Self-Service

Kiosks and Self-Service

Infrared touchscreens are ideal for interactive kiosks, such as information kiosks, self-service pay machines and ticket machines. Their robustness and reliability in public areas make them a popular choice. They function flawlessly even under heavy use and changing conditions.

Industrial Control Panels

In industrial environments, these screens are used for operating machinery. They are resistant to dust, moisture and scratches. A major advantage is that they can be operated with gloves on, which is essential for safety and efficiency in many factory settings.

Medical Equipment

This technology is used in medical devices, such as patient monitors and imaging systems. The high image clarity, because there is no extra layer on the screen, is crucial for the accurate display of vital medical data and diagnostic images.

Gaming and Entertainment

In slot machines and arcade cabinets, infrared touchscreens offer a fast and responsive gaming experience. Support for multi-touch and durability to withstand heavy use make this technology well suited for the entertainment industry.

High Durability

Because the touch components are incorporated into the bezel, the screen surface itself is very robust. It can be made of tempered glass that is resistant to scratches, moisture and dirt. This makes IR touch screens ideally suited for demanding environments, both indoors and outdoors.

Multi-Touch Capacity

The technology supports multiple simultaneous touch points. This enables intuitive control via multi-touch gestures, such as zooming and rotating. It is an essential feature for modern software, interactive presentations and collaborative applications.

Excellent Image Clarity

Because no additional sensor film or layer is applied to the screen glass, image quality is not affected. This results in superior brightness, high contrast and vivid colors, which is ideal for digital signage and applications where visual detail is important.

Versatile Input

One of its greatest advantages is its flexibility in input methods. The screen responds to any interruption of IR rays, whether caused by a bare finger, gloved hand, stylus or other object. This makes the technology widely applicable.

Summary

An infrared (IR) touch screen detects touch by interrupting a grid of invisible infrared rays. Integrated into the edge of the screen are LEDs and sensors that create a network of horizontal and vertical light beams. When a finger, stylus or other object touches the screen, a beam is blocked.
