Owing to its flexibility, optical infrared (IR) is another highly popular technology. Notably, IR is the only touchscreen that operates without a film or glass cover layer. Instead it relies on infrared light-emitting diodes projecting an invisible grid of beams that register touch wherever light is disrupted. It offers great clarity, is easy to calibrate, and lasts a long time, too, since there’s no flexible layer to degrade over time. The main drawback is the presence of a noticeable gap between flat panel and IR sensors. For this reason it’s less suited for industrial and highly trafficked applications where high-pressure dust, debris or liquid might harm the electronics inside the LCD panel. The optics are clearer than resistive or capacitive touch, it provides a rugged surface that manufacturers can bezel and seal against dust and moisture, and it supports multi-touch and dual-touch inputs. Produced mainly at sizes larger than 32 inches, IR technology is ideally suited for use with kiosks, or self service machine, outdoor installations, point-of-sale systems, factory automation, and other applications where bare fingers are impractical – from industrial and pharmaceutical environments to retail, hospitality, and service industries.
The Premio Touch
Although MC Hammer couldn’t have foreseen that U touching it would be so easy, he might’ve guessed that the technology behind it would be so sophisticated. Before investing in any industrial display, however, first we have to weigh the pros and cons of functionality, durability, aesthetics and cost. We also have to consider the time and effort required to maintain and calibrate the device so that it performs optimally in its particular industrial environment. Fortunately, Premio specializes in helping clients identify the right technology for the job. With a Class 10,000, dust-controlled clean room dedicated to touch-sensor lamination at our headquarters in Greater Los Angeles, Premio offers extensive expertise integrating and manufacturing award-winning, touch-enabled products for a broad range of industrial uses. In fact, we’ve been providing solutions for original equipment and design manufacturers for more than 28 years.
