What is an infrared touchscreen?

An infrared touchscreen detects touches by interruptions in an invisible grid of infrared light. LEDs and phototransistors are built into the frame around the screen, creating horizontal and vertical beams of light. When a finger or object touches the screen surface, specific light beams are blocked. The coordinates of this interruption are calculated and transmitted as a touch point, without the need for physical pressure on the screen.

Interactive Kiosks

Interactive Kiosks

These screens are ideal for public kiosks, such as information kiosks, ticket machines, and self-service points. Their robustness and the fact that the technology does not depend on a conductive object (such as a finger) makes them reliable in various public environments. The durable glass plate is highly resistant to intensive use.

Interactive Whiteboards

Infrared touchscreens are often used in interactive whiteboards for education and business presentations. They make collaboration intuitive by allowing users to write and navigate directly on the large screen. The technology supports large formats and multi-touch, which is essential for group interaction.

Industrial Control Panels

Reliability is crucial in industrial environments. Infrared touchscreens are insensitive to dust and dirt and can be operated while wearing gloves. This makes them ideal for HMI (Human-Machine Interface) panels in factories and control rooms, where conditions are often demanding.

POS systems (POS)

Point-of-sale (POS) systems in retail and hospitality benefit from the speed and durability of IR touch. The technology responds quickly to finger or stylus touches, increasing transaction speed. The screens are easy to clean and resistant to the wear and tear of daily, intensive use.

High Light Transmission

Because no additional layers or coatings are required on the glass for touch functionality, infrared screens offer superior brightness and image quality. Light transmission is very high, resulting in vivid colors and sharp images without distortion or parallax effects.

Stable and Reliable

Operation is not affected by static electricity, voltage, or power fluctuations. This makes the technology highly stable and reliable, even in environments with electromagnetic interference. The screen continues to function accurately without the need for frequent recalibration.

Scratch-resistant and durable

The touch components are integrated into the frame, allowing the screen surface itself to be a durable, scratch-resistant glass plate. This protects the underlying display and touch technology from wear and damage, resulting in a long service life even with intensive use.

Multi-touch & Object Detection

Infrared technology supports multi-touch, allowing multiple touch points to be registered simultaneously. Because the technology responds to any interruption of the light beams, it can be operated with fingers, gloves, a stylus, or any other opaque object, offering maximum flexibility.

Summary

An infrared touchscreen detects touches by interruptions in an invisible grid of infrared light. LEDs and phototransistors are built into the frame around the screen, creating horizontal and vertical beams of light. When a finger or object touches the screen surface, specific light beams are blocked. The coordinates of this interruption are calculated and transmitted as a touch point, without the need for physical pressure on the screen.
