An infrared touch screen is a type of touch sensor that uses an array of infrared light beams across the display. When a user touches the screen, the interruption of these light beams is detected, allowing the system to determine the touch's location. This technology is widely used in public information kiosks, interactive displays, and other applications where durability and multi-touch capabilities are essential.
Infrared touch screens operate on a simple principle of detecting the disruption of infrared light beams. Typically, a grid of infrared emitters and receivers is arranged across the surface of the screen. When an object, such as a finger, intersects the path of these light beams, the system calculates the precise coordinates of the touch based on which beams are interrupted.
Infrared touch screens offer several key benefits:
Infrared touch screens are used in numerous environments:
The market for infrared touch screens is growing significantly. According to a recent report from Markets and Markets, the global touch screen market is estimated to grow from $61.0 billion in 2020 to $90.0 billion by 2025, at a CAGR of 7.0%. This growth can be attributed to the increasing adoption of touch-enabled devices across various sectors, including retail, healthcare, and education. In particular, the infrared touch screen segment has been noted for its substantial contributions to this growth.
