Over the years, Capacitive and Resistive touch screens have been widely used as the two most reliable touch-sensing technology. However, original equipment manufacturers (OEMs) have an excellent choice for touch sensors &#; IR (Infrared) Touch Screens. For applications where capacitive or resistive touch technology doesn&#;t fit right, IR touch screens are considered the best alternative.

Here&#;s an overview of IR touch screens to understand how they work and the advancements offered by A D Metro in this technology.
Overview of IR- Infrared Touch Screens Technology
The process of identifying the touch command in IR touch applications is totally different and unique when compared to its counterparts. Resistive touch screen devices are pressure activated and register the touch command when their upper and bottom layers are pressed against each other, and capacitive touch sensors detect touch commands by measuring changes in capacitance or by capacitively coupling X and Y elements together. IR touch screens, on the other hand, identify touch commands with interruptions in uniform beams of light.
An infrared touch screen application is composed of a frame outfitted with LEDs and photodetectors. The frame has an optical bezel or protective cover that enables LEDs to emit infrared beams, invisible to the naked eye. This process creates an optical grid on the display&#;s surface, and during the touch event, it blocks some of the light beams, allowing photodetectors to detect these interruptions.
Why IR Touch Screens are the Best Alternative to Other Touch Screen Technologies
IR (Infrared) touch screens are considered the perfect alternative to conventional touch screens. The following reasons make them the ideal choice of OEMs:
Advancements in Infrared (LCIR) Touch Technology by A D Metro
The mentioned advantages no doubt give good reasons to use IR touch screens, however, to make this technology more efficient to use A D Metro has developed Linear Correlating Infrared (LCIR) touch technology.
IRTOUCH contains other products and information you need, so please check it out.
A D Metro&#;s innovative LCIR solution is an excellent choice for applications that require multi-touch features but have difficulty integrating projected capacitive (PCAP) touch sensors. Even when exposed to challenging environments such as strong radio frequency interference (RFI) and full sunlight interference, LCIR technology offers:
Linear correlating infrared technology (LCIR) can tolerate any sunlight exposure, including strobing sunlight which is important for applications used in helicopters for instance. LCIR offers consistent performance across temperature and pressure extremes.
CDS offers LCD Panel Kits and Touch Solutions from stock which include Display panels with interface card and Control OSD and Cable-Set, including Embedded Touch Displays and Touch Screen Components. The CDS kit solutions include a display and the driving electronics such as AD board and backlight drivers all in one package optimised for the panel of your choice. Many of the CDS displays are configured with a controller card, and internal cable sets with each of these combinations set up as an LCD display kit which ensures a single part number can be ordered at any time and our customers are guaranteed consistency of supply.
But some of our customers require TFT display kits that are slightly different to a standard kit, with for example a different firmware. For these unique part numbers are created for each customer&#;s TFT display kit solution, again ensuring that traceability and consistency is guaranteed within each and every one of our TFT display kits. This could also include the different ways the internal components are handled, e.g. a medical or military company may require 100% incoming testing rather than batch testing and a unique part will identify this requirement and ISO procedures ensure the process and reliability. Applications include touch screen kiosk , touch window, industrial touch screen, industrial touchscreen monitor, touch screen tv.
Whatever your display kit solution we can deliver this for you at a very cost effective price. Just contact our technical sales team to discuss your requirements and they will create an optimised solution for you. Even if you are having issues with your current supplier we can often offer lower cost Form Fit and Function solutions to give you that improved performance and solution you require.
