What is an infrared touchscreen?

An infrared touchscreen works via a grid of invisible infrared rays. LEDs and sensors are placed around the edge of the screen, creating horizontal and vertical beams of light. When a finger or object touches the screen, some of these beams are interrupted. The coordinates of this interruption are calculated by the controller and registered as a touch. This technology does not require physical contact with the glass surface, which increases durability.

Interactive Kiosks

Interactive Kiosks

Infrared touchscreens are ideal for public kiosks, such as information points, wayfinding systems, and self-service terminals. Their robust and durable design can withstand intensive use in public environments, which benefits the reliability and service life of the installation.

Industrial Control Panels

In industrial environments where operators often wear gloves, infrared screens offer a reliable solution. Because the technology responds to the interruption of light rather than pressure or capacitance, the screen can be operated with any type of glove or stylus, even in demanding production conditions.

Cash and Ticket Machines

Durability is crucial for ATMs, parking meters, and ticket machines. The technology is highly resistant to vandalism, scratches, and various weather conditions. Reliability is not affected by dirt or water on the screen, which is essential for outdoor applications.

Education and Training

This technology is widely used in large-scale interactive whiteboards for classrooms and training rooms. The multi-touch functionality enables collaborative working, while the excellent image clarity ensures an optimal visual experience for all participants.

High Durability

Because touch detection takes place in the edge of the screen, the glass itself is not an active part of the touch system. This makes the surface highly resistant to scratches, wear and tear, and vandalism. The screen continues to function even if the glass is damaged, ensuring a long service life.

Outstanding Image Quality

Unlike other touch technologies, no additional layer is placed over the display. This means that there is no reduction in brightness, contrast, or image sharpness. Light transmission is optimal, resulting in superior visual clarity and color reproduction.

Flexible Input Methods

A major advantage of infrared technology is that it detects any interruption of the light beams. This allows the screen to be operated with a bare finger, a gloved hand, a stylus, or any other opaque object. This makes the technology highly versatile in a variety of usage scenarios.

Multi-touch Capacity

Modern infrared touchscreens typically support multiple simultaneous touch points (multi-touch). This is essential for interactive applications where multiple users operate the screen at the same time, such as digital whiteboards, games, or collaborative design tables.

Summary

An infrared touchscreen works via a grid of invisible infrared rays. LEDs and sensors are placed around the edge of the screen, creating horizontal and vertical beams of light. When a finger or object touches the screen, some of these beams are interrupted. The coordinates of this interruption are calculated by the controller and registered as a touch. This technology does not require physical contact with the glass surface, which increases durability.
