Infrared touch screen

Types of infrared touch screens

An infrared touch screen detects touches by sending invisible infrared light grids across its surface. When a user touches the screen, the light beams are interrupted, and the exact location of the touch is determined through the interruption pattern. There are different types of infrared screens, and they include;

• Active IR touch screens

  They contain an array of infrared emitters and detectors placed around the screen’s perimeter. The system uses active infrared light, typically with longer ranges, and more powerful emitters. The emitters are generally laser diodes that project infrared light, which is then detected by photosensitive detectors. The lasers are pointed in a specific pattern, usually in horizontal and vertical lines, where the lasers’ intersections are detected by the sensors. When a finger or object touches the screen, it blocks some of the emitted laser beams, and the system can determine the touch coordinates based on which beams are interrupted.

• Passive IR touch screens

  Unlike the active screens, the infrared light used is passive, meaning that the touch screen relies on the ambient infrared radiation in the environment rather than emitting its own. The screen has photodetector sensors that can pick up on the ambient infrared light, and when a finger or object comes into contact with the screen, it blocks the infrared light. The system then determines the touch coordinates based on where the light is interrupted. These types of infrared touch screens are less common and less accurate. They may also not work well in places with low ambient infrared radiation.

• Hybrid IR touch screens

  They combine both the active and passive infrared touch screen technologies. The hybrid design often enhances the accuracy, sensitivity, and performance of the touch screen. Infrared light is emitted from laser diodes, and photosensitive detectors around the perimeter of the screen can detect the light. The system can switch between active and passive mode, utilizing the advantages of both technologies. Interruption of the infrared light beams, in either mode, helps determine the coordinates of the touch.
