Why Infrared Touchscreens Becoming Popular

 

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. 

Moreover, A D Metro - one of the leading manufacturers and suppliers of innovative touchscreen solutions, offers Linear Correlating Infrared (LCIR) touch technology. It is an excellent choice for applications that require multi-touch but have difficulty integrating projected capacitive (PCAP) touchscreens. This innovative touch solution by A D Metro is ideal for automotive, aviation and medical applications, where ultra-reliable touch screen function is essentially required. This Linear Correlating Infrared (LCIR) touch technology offers 100% sunlight immunity which no other IR touch technology can as well as 100% optical clarity and maximum contrast, reliable two touch functionality and input compatibility with gloves and 5mm stylus.

The Fundamental Concept of Waterproof Touch Screens

Image
  Several commercial fields require waterproof solutions for their operational equipment, and touchscreen devices are no different. Whether it is military, marine, or industrial applications, they all need waterproof touch screen devices. In fact, waterproof touch displays are a top technological solution, offering ease of use in outdoor environments.   However, not all touch screen solutions come with waterproofing technology. Particularly, conventional touch screens do not feature robust solutions as required in industrial applications or extreme outdoor environments, necessitating the integration of advanced solutions. What is Waterproof Touch Screen Technology?  Waterproof displays or touch screen monitors refer to sealed properties of the sensor face and housing to prevent dust, dirt, and moisture contamination. An Ingress Protection (IP) rating such as IP-67 is a common standard to identify the equipment seal quality. However, a good seal does not mean the eq...

5-Wire Resistive Touch Screens Now Offer Multi-Touch Features with an Advanced Two-Touch Controller

Image
Touch screens supporting multiple points of simultaneous touch are not uncommon in the market. Referred to as a multi-touch feature, it widens the input capabilities of devices. A touch screen offering the multi-touch feature, usually allows input using two fingers, for example, pinching on the screen will zoom the display in or out. Two finger touching can also enable the rotating of an image. This is just one of many features of using multi-touch. Earlier, there were not many options for touch screens supporting multi-touch, and capacitive touch screens were the most common choice for reliable solutions. In fact, manufacturers were only using its advanced Projected Capacitive version, but this touch technology has its own limitations: It uses human capacitance to detect touch commands which makes it difficult to use in industrial settings;   It doesn’t support touch input through gloved fingers (thin or surgical gloves may work). If stylus usage is required, then a special c...
