These days, just about everyone has a touch screen in their pocket, at work, or at the bottom of their bag; thanks to smartphones and tablets, they’ve become commonplace at home and in the office, but they’re also changing far more than just the ways we answer email or watch TV. Touch screens are poised to change the way we shop, eat out, drive, work, and travel, not to mention enterprise applications in industry, transportation, aerospace and medical.
Given how many applications for touch screen technology exist, as a solutions provider, you need to work with a touch screen supplier with the versatility and innovation to meet your demands and keep your clients satisfied. There are manufacturers that design and manufacture solutions in a wide range of markets, from gaming and entertainment to points of sales and industrial automation. One such manufacturer, A D Metro, works closely with it partners to design and integrate their touch screens. An innovative common controller used with their PCAP touchscreen also reduces one-time engineering costs and speeds up your delivery to market schedule. Your supplier should work closely with you on analysis, design, prototyping, sourcing, testing, and integration.
There are three primary touch screen technologies used in the majority of applications; manufacturers can also provide customizable options when it comes to features like optics, glass thickness (surface and substrate), and chemically strengthened backers.
Surface Acoustic Wave: Primarily used in gaming, SAW touch screens are characterized by superior optical performance, light touch, and a durable surface with no coatings on the glass plate sensor.
PCAP Touch screens: One of the most widely used options, this is the same multi-touch touch screen you find in your phone. It uses a glass-on-glass sensor that relies on the conductive properties of human skin, which is why you can operate your phone with your fingers but not if you’re wearing gloves. It provides clear images and the multi-touch operation makes it suitable for more interactive tasks.
Resistive Touch screens: These are widely used in ruggedized applications such as industrial PDAs and public kiosks as they are built to be more durable than their capacitive counterparts. They can be operated either with a finger or a stylus, as the sensors rely on the contact of two layers of glass.
Beyond standard resistive technology, the ULTRA resistive touch screen designed by the company A D Metro delivers a new standard of ruggedness that can be applied in the most demanding applications. These include public kiosks (like ATMs) that are left out in the weather in all climates or heavily trafficked, industrial PDAs and control panels that are dropped, gouged, impacted, and hosed down, and control panels used in aerospace or marine technology. The ULTRA resistive touch screen is uniquely suited to mission critical functions, as it’s tested for over 5 million operations, and it’s designed to prevent shattering andspalling. That means the sensor is still functional even after repeated impact trauma, scoring, or gouging, such as you might see due to vandalism in an unsupervised, exterior location. Superior touch screen technology is essential to any systems integrator that wants to provide unsurpassed technology solutions to their clients in any industry.
