What is an Infrared (IR) Touchscreen?

An infrared touchscreen functions by detecting interruptions in an invisible grid of infrared rays. Arranged in the frame around the screen are rows of IR LEDs and photodetectors that create a grid of light rays. When an object, such as a finger or stylus, touches the screen surface, a beam is blocked. The coordinates of this interruption are calculated and recorded as a touch point. This technology does not require pressure or a conductive object.

Industrial Control

Industrial Control

Infrared touchscreens are ideal for industrial environments and control rooms. Rugged construction and the ability to operate the screen with gloves make it suitable for harsh environments where reliability and durability are essential.

Interactive Kiosks

For both indoor and outdoor kiosks, such as ticket machines and information kiosks, IR technology offers a reliable solution. It stands up well to intensive public use and various environmental influences, and provides a consistent user experience.

Education and Presentation

Large interactive whiteboards in classrooms and meeting rooms often use infrared technology. It allows scalability to very large sizes and provides an intuitive multi-touch experience for collaboration and education.

Retail and Gaming

In retail automation, such as at cash registers (POS), and in the gaming and entertainment industry, this technology is used because of its fast and reliable response. Its durability is a major advantage in frequent use by changing users.

Flexible Operation

A key advantage is that the screen can be activated with virtually any opaque object: a bare finger, gloved hand or stylus. This makes the technology extremely versatile in a variety of use cases.

High Durability

Because the touch sensors are embedded in the bezel and there is no sensitive layer on the screen, the glass surface is highly scratch-resistant and durable. This extends the life of the device, even with intensive public use.

Superior Image Quality

Because there is no additional sensor layer over the display, light transmission is not hindered. This results in optimal brightness, sharpness and color reproduction, ensuring an excellent visual experience without parallax errors.

Stable and Reliable

Infrared touchscreens are stable and 'drift-free,' meaning they do not require periodic recalibration. They are also impervious to dirt, dust or water on the screen surface, which increases overall operational reliability.
