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.

Although 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.


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.

Quick and Effective Help Close to Hand in Case of Windows Installer Problems

It is quite common for people who have been using Windows on their computer for a long time, to face issues with the Windows installer in starting up their PC. This is generally the most irritating and persistent problems, among a host of other issues that cause frustration and hamper productivity. There are a number of issues that might plague a user, but all these problems are not insurmountable. One of the many problems faced by average users on a regular basis, is that of Windows Installer problems. Simple attempts to remove or install applications will not work, or will cause further odd symptoms and strange errors. Typically, many users freeze up when they face computer issues. Anyone who is unfamiliar with computers will surely feel at a loss when they realize that something out of the way is happening. Most will definitely feel helpless and throw up their hands in utter frustration.

Increased productivity, which is a hallmark of today’s world where everything is run and managed by computers, gets hampered in the case of such errors popping up. Computers not only simplify our work, but is also the preferred medium of connectivity and entertainment. It is through computers that most people stay connected with friends and family no matter where they are geographically placed. Lost revenue, missed opportunities, lack of connectivity is some of the evils that haunt us when we face Windows installer problems.

When there is a segment of the program installer that is missing, corrupted, or deleted, Windows installer problems generally crop up. Sometimes an installer error appears when a component goes missing from your PC, as the program installer cannot carry on installing without that omitted component. Now the question arises as what can be done to avoid these errors. We have all heard the adage that ” prevention is better than cure”! PC checkups and periodic maintenance works, regular defragmentation, deletion of unnecessary junk files are some of those preventive measures that one can resort to.

There are simple ways to solve such problems, like a restart of the machine. But it’s only in cases where the problem is superficial that such measures can be applied. It is only prudent that other steps be taken in cases where the problem is deeper or more complicated. A good registry cleaner will help you to permanently solve Windows installer problems. So, there is no need to feel utterly helpless in such situations. This kind of cleaner can be downloaded from the net, and in a few clicks, the software will scan your PC, repair the problem, and make it run like a brand new machine. All this can be done from the comfort of your own home or office, without the hassles of actually carrying your machine physically to a repair shop. A good registry cleaner works quietly and efficiently and acts as a PC optimization tool as well as a PC cleaner. It also provides outstanding anti spyware and antivirus protection. It is the best way to adjust all your system settings at once.

Fundamental Data About The Computer

A PC is not an acronym and here and there truncated as comp or ‘puter. The expression “PC” was initially given to people (human PCs) who performed numerical counts utilizing mechanical adding machines, for example, the math device and slide principle. The term was later given to a mechanical gadget as they started supplanting the human PCs. Today’s computers are electronic gadgets that acknowledge (information), prepare that information, produce yield, and afterward store (stockpiling) the outcomes.

The primary computerized PC and what a great many people consider as a PC was known as the ENIAC, worked amid World War II (1943-1946). Early PCs like the ENIAC utilized vacuum tubes and were vast (once in a while room size) and just found in organizations, universities, or governments. Later, PCs started using transistors and in addition littler and less expensive parts that permitted the normal individual to possess a computer.

Today, PCs make occupations that used to be confounded much less difficult. For instance, you can compose a letter in a word processor, alter it at whatever time, spell check, print duplicates, and send it to somebody over the world in a matter of seconds. These exercises would have taken somebody days, if not months, to do before PCs. Likewise, the greater part of the above is only a little division of what PCs can do.

Today’s PCs have a few or the greater part of the underneath segments (equipment). As innovation advances, more established advances, for example, a floppy plate drive and Zip drive (both demonstrated as follows), are no more required or included with PCs.

• Bay

• Case or Chassis

• Case Fan

• Optical drive: Blu-beam, CD-ROM, CD-R, CD-RW, or DVD

• CPU (processor)

• Floppy plate drive

• Hard drive

• Keyboard

• Memory (RAM)

• Microphone

• Monitor, LCD, or another presentation gadget

• Motherboard

• Mouse

• Network card

• Power Supply

• Printer

• Sound card

• Speakers

• Video card

At the point when discussing a PC or a “PC”, you are normally alluding to a conventional PC that you would discover in a home or office. Today, be that as it may, the lines of what makes a PC are obscuring. The following are all the diverse case of what is viewed as a PC today.

Above, is only a couple of the most surely understood PCs and a case of exactly how distinctive PCs can look today. The following is a finished rundown of PCs of over a wide span of time.

Console (e.g. Xbox and PS3)

Diskless workstation and Thin customer

Implanted PCs – The most widely recognized and utilized PC. An implanted PC is a PC with a particular capacity found in such things as ATMs, autos, microwaves, TVs, the VCR, and other home hardware.

Cross breed PC

Tablet, versatile, scratch pad computer

Centralized server or Supercomputer





PC (otherwise known as desktop and home computer)


Set-Top box

Cell phone


Who makes PCs?

Today, there are many organizations that make and construct computers, on the off chance that you get the majority of the essential parts for a PC you can even make your own PC. See our PC organizations page for a posting of organizations (OEMs) that make and fabricate PCs.
