Capacitive and Resistive touch technology has been extensively used in a wide range of applications, particularly with their advanced versions. However, for applications in which these two touch technologies don&#;t integrate well, Infrared (IR) Touchscreens might be the best option.

What Is An Infrared Touchscreen?
Applications with IR touchscreens support touch-based input in a similar way, as other touch technologies. However, the method by which IR touchscreens identify touch commands is entirely unique and happens with interruptions in uniform beams of light.

An infrared touchscreen is composed of an LCD monitor with an IR touch frame mounted around its perimeter. The IR touch frame is composed of Infrared LEDs and photodetectors. The frame has an optical bezel or protective cover through which IR LEDs emit infrared beams, invisible to the naked eye, creating an optical grid on the display&#;s surface. When any touch event happens, it blocks some of the light beams and Photodetectors installed across detect these interruptions. The controller electronics can then identify the touch location by which beams of both the X and Y axis&#; are blocked.

Benefits Of Infrared Touchscreen Technology
But what exactly makes IR touchscreens included in the topmost choices for touch applications. The following benefits of infrared touch technology would be the answer to this question.

• Economical option &#; In comparison to other touch technologies, cost of IR touchscreens is relatively cheaper in large sizes.
• Supports multi-touch &#; Infrared touchscreens support multi-touch and therefore, often replace Projected Capacitive technology in many applications that allow multiple touch features.
• Short response time &#; Usually less than 8ms, Infrared touchscreens confine touch events by detecting light interruption, so they are quick to respond with actions accurately.
• Withstand scratches &#; The LCD monitor comes protected with a glass overlay that helps avoid scratches on the display screen.
• Flexibility in customizing screen sizes &#; IR touchscreens can fit with any custom-made monitor by simply adjusting numbers of LEDs and photodetectors embedded in the overlay frame.
• works well with 4K displays &#; Picture clarity is supported by great resolution. IR touchscreens integrate well with 4K resolution screens.
  Operated with anything &#; IR touchscreen applications can be operated with anything, a bare finger, a gloved finger, wet hands, or even a stylus pen.

Conclusion:
Given the benefits and specific requirements, Infrared Touchscreens are much in demand for a wide range of applications.
