Infrared (optical) touchscreen technology and how it works

The infrared touchscreen technology is one of the most reliable touchscreen technologies. Unlike capacitive touchscreens, infrared touchscreens don’t require any patterning on the glass which increases durability and optical clarity of the overall screen and system.

Infrared touch technology works by using an array of X-Y infrared LED and photodetector pairs around the screens edges, which essentially creates a vertical and horizontal grid system and pattern. These are then used to detect any form of disruptions of the LED beams, which indicates to the sensor the location of the touch (also referred to as ‘beam break’). It correlates this and essentially provides an X and Y co-ordinate, which is where the touch is located. This is similar to SAW technology but infrared uses infrared light beams and not ultrasonic waves.

 

One reason for infrared being used particularly in outdoor and point of sale systems, is that it can detect any input including fingers, gloved fingers, pens and stylus, meaning that it doesn’t require just one element to induce the touch screen location element. This offers more flexibility for the users of the screen and application, but you also have to be careful with regards to the screen for keeping it clean and making sure there is initially nothing on the screen which could disrupt any potential beams too.

The advantages to using infrared touch screen technology:

· No need for multiple layers for the screen so it has a high clarity

For this reason

· Can be sealed and protected against weather and contaminants

· Can be used with gloved or wet hands which is a good advantage

For many sectors

· Lasts a long time and is durable as there’s no need to apply any

Pressure

· Performs in just about any indoor lighting environment

· Is economical and can scale up to larger displays

· Responds to any input: finger, pen, stylus, bank card

· Accurate touch, short response time, up to 40 simultaneous touch

Points

· Monitor and touch overlay are discrete, allowing for upgrades or

Easy replacement

· Wide range of applications: outdoors, medical, industrial
