What Is the Technology Behind a Touch Screen?

Have you ever wondered just how the touch screen on your cell phone, tablet, LED television, or any other device actually works? It is amazing to think that we can now issue commands to our devices with the touch of our hand and while this technology might seem new, it has actually been around since the 1960's.

In fact, the technology behind the touch screen can actually traced right back to the 1940's but it was only two decades later that it actually became feasible to use on a large scale.

ATMs have been using technology since 1965 which is when E.A. Johnson invented the first finger-driven touch screen that actually used the same capacitive touch mechanism that is still used in cell phones and other devices to this day.

According to Roger Samara, there are other types of touch screen technology such as resistive touch or multi touch technology, capacitive touch technology is the one that is preferred for mass produced consumer products.

How is a Capacitive Touch Screen Made?

Today, a capacitive touch screen works through the use of an ITO touch film that is attached to the screen. This touch film is basically a semiconductor that has been printed out using semiconductor manufacturing methods such as roll to roll processing which uses a roll to roll evaporator system to create an electronic device on a flexible plastic.

A roll to roll evaporator system from industry leading manufacturers are able to mass produce ITO touch film that can be used on various devices such as smart phones, LCD or LED screens, tablets, and PC monitors.

Roll to roll technology is the preferred method over other technologies such as roll to plate and plate to plate technologies due to it offering a continuous process and higher throughput than the others. That ITO touch film is then programmed using software that enables us to give our devices instructions through the use of our fingers on the screen.

In fact, semiconductor manufacturing processes such as the roll to roll evaporator system are used for many other products too, such as solar panels, cameras, and printers.

Summary

So now you have a basic idea of where technology came from and the technology that is used to produce the semiconductor film that is used on touch screens today. Without machines that use a roll to roll evaporator system, we would not be able to enjoy the many touch screen devices that are available to us today.

Summerlin Air Force veteran carves niche as computer technician

Roger Samara | Summerlin Air Force

When Kevin Hoffnagle left the Air Force after serving in Afghanistan, he found it tough to get a job.

He didn’t find anything for a year. Then he turned to Veterans Affairs, who set him up with The Learning Center, 777 N. Rainbow Blvd., Suite 150.

Hoffnagle used his GI benefits to train as a computer technician. He was familiar with the work; he once took apart and rebuilt his computer. Without a car, he walked an hour each way to training.

“I’m real fit now,” he said. “It made me lose weight.”


The course was six weeks of classroom instruction, followed by a three-month unpaid internship. Besides vocational training through the VA, The Learning Center offers Purple Heart recipients a 12-day Microsoft Office Suite course (usually $2,595 ) free.

Hoffnagle’s internship was done at TLC Computer Solutions, 7501 W. Lake Mead Blvd., Suite 112. Owner John Sinchak said he considered hiring Hoffnagle after the 12-hour a week internship was over, but said it would take another six months to get him trained for a technical position that was opening up. So he kept him on over the summer to see how did.

“We knew Kevin was dealing with post-traumatic stress disorder and we knew about his back injury, so he came to us with those issues, which might be a deterrent to hire on a regular basis,” Sinchak said. “… Because he’s put so much effort into the program, we wanted to work with him and bring him into the organization.”

Hoffnagle proved to be a good fit as a back-room technician.

“I think this is the kind of environment that is good for him. It’s small enough we can keep close tabs on him, where in a larger business he might get lost in the shuffle,” Sinchak said.

This Christmas, Hoffnagle became certified and is now gainfully employed at TLC.

Part of the reason, Pinchas admitted, that he was working with The Learning Center was because the program provides a rebate for the veteran’s salary for a few months. Hoffnagle also received an allowance from the VA, covering tools, equipment, clothes and other items he might need during training.

“Since I know what I want to do now, it helps me (increase) my knowledge base,” Hoffnagle said. “To have this program available, it gives you a safety net you can use, even though you have to be a certain percentage disabled to use it. They get you into a (career) you can be good at.”

A fellow worker, Matthew Winther, had nothing but praise for how the Air Force prepared Hoffnagle for approaching any job.


“Kevin’s a real hard worker,” he said. “He’s got that military attitude. He comes to work and gets right to it. If I didn’t make him stop, I’m sure he’d still be here when I come back the next morning.”
