A touch screen is a device that allows input and output usually made up of a layer of information processing system and a visual display. By using fingers or a special stylus pen for touching the screen, users can control the information processing system or input data through multi-touch or simple gestures. Some touch screens can work only with a special stylus pen, while others may work with gloves. The users can control how the information is displayed on the touch screen or interact with what is displayed by, for instance, zooming in the image in order to increase the text size.

The benefits of using a capacitive touch screen display

The advantage of the touch screen technology is that it is enables users to directly react to the data displayed, instead of employing an intermediary device such as a touchpad or mouse. Touch screen technology for monitors is commonly used in various gadgets and devices such as electronic voting machines, game consoles, smartphones, tablet computers, personal computers, and point of sale systems. Touch screens could be also attached as network terminals of just used as stand alone computers. They have also a significant role in digital appliances such e-readers or PDAs (personal digital assistants).

The increase in popularity of tablets and smartphones is supporting the demand for touch screens to be used in functional and portable electronics. Touch screens are also found in the heavy industry, medical field, ATMs (automated teller machines), museum display and kiosks or room automation. They are implemented as a viable solution for situations where mouse and keyboard systems cannot be used as suitably accurate, rapid, or intuitive means of interaction with the content on the screen.

The touch screen controller based firmware and sensor have been made available, historically, by a various after-market system integrators, and not by motherboard, chip and display manufacturers. However, chip manufactures and display manufacturers worldwide have acknowledged in the last few years the trend toward a wide acceptance of touch screen user interface components as a highly desirable alternative and have begun to integrate this technology into the design of their products.

Nowadays, touch screen monitors are used everywhere. One of their greatest advantages is the fact that they are very easy to use. A touch screen can be used like an invisible keyboard, but it displays only as much button choices and data as users need to complete a particular task. This is one of the reasons why these devices are increasing in popularity in various applications from industrial machinery to kiosks and mobile phones.

In selecting the most suitable touch screen monitor for your application, the most important decision is in regard to the type of touch screen technology to use. Touch screens come in several types based on a few different technologies, each with its own advantages and disadvantages. Among them, capacitive touch screen monitors make one of the most common.

faytech large capacitive touch screens and surface capacitive touch screens

A capacitive touch screen panel is made of an insulator coated with a transparent conductor. The most common material used as an insulator in touch screens is glass. As a transparent conductor is usually used indium tin oxide.

How does a capacitive touch screen panel work?

Touching the surface of the monitor creates a distortion in the electrostatic field of the screen, as the human body is also an electrical conductor. The resulted electric distortion can be measured as a change in capacitance. In order to determine the touch’s locations can be used various technologies. Then, the location is sent for processing to the controller.

The difference from a resistive touch screen, is that users cannot work with a capacitive touch screen through gloves and other types of electrically insulating material. In consumer electronics, this is a disadvantage because capacitive smartphone and touch tablet PCs cannot be used in cold weather. However, this disadvantage can be overcome with a special-application glove or a special capacitive stylus.

The top manufacturers of capacitive displays continue to develop more accurate and thinner touch screens. For instance, by building the capacitors inside the display itself, touch screens for mobile devices such as Samsung’s Super AMOLED screens are being produced now with “in-cell” technology that eliminates a layer. This touch screen type reduces the visible distance between what the user is touching on the screen and the user’s finger, enabling gestures and taps to be more responsive and creating a more direct contact with the content displayed.

There are two main types of capacitive touch screen monitors: projected capacitive touch screens and surface capacitive touch screens.

Touch screens based on projected capacitive technology deliver interactive solutions for various applications and industries including aerospace, medical, military, and industrial. Multi-touch projected capacitive technology has changed forever the way we interact with machines since the iPhone exploded on the market in the year 2007. Touch screen monitors with projected capacitive technology offer many substrate choices and stack-up options, delivering unmatched durability and outstanding optics.

Among their features are included:

• Wear resistant

• Multi-touch capable

• Works with water

• Operate in environmental extremes

• Abilities for high resolution

• Exceptional optics

• Flexible sensors

• Glove, finger, or passive pen input

• Touch coordinates are drift free

• Plastic or glass cover lens

The more common approach is based now on mutual capacitance. If they are placed close together, the majority of objects with conductive proprieties can hold a charge. When another conductive object bridges the gap (a finger, for example), the interrupted charge field is being detected by the microcontroller.

Surface capacitive touch screens

Touch screen monitors based on surface capacitive technology offer environmental robustness and increased durability. These touch screen monitors are proven to meet the harsh demands found in vandal prone access sectors, and areas with high traffic. Curved and flat surface capacitive touch screens are suitable for graphic driven applications, such as vending machines, entertaining, gaming, banking and ATMs.

How does an ips capacitive touch screen work?

The surface capacitive touch screen comes with a conductive coating on top of the front surface. The conductive coating features wires connected to each corner. To each of these four corners is applied a small voltage. The operation of touch screens based on surface capacitive technology relies on the capacitance of the human body. A small current flows to the point when you touch the screen, causing a voltage drop that is then sensed at corners.

Touch screens based on surface capacitive technology can be used easily on larger size (over 12 inches) applications. Because the structure is only one glass layer, they provide high light transmission (in the range 88 to 92 percent) and excellent optical clarity. Of all the available technologies, surface capacitive tech has the fastest touch response time. These monitors can also withstand regular cleaning using harsh chemicals.

How capacitive touch screen interface technology will change your business

Because capacitive touch screens are based on a durable technology, they can be employed in applications that require increased durability. Among their areas of application are included point-of-sale systems, kiosks, and industrial computer machinery. Another advantage of capacitive touch screens is that they have a higher clarity than resistive-type (higher by 88-92 percent). They also provide you a greater endurance than a resistive type (up to 225 million touches.

You can make your decision to employ capacitive touch screens based on the following factors:

• Interface: Your computer should communicate with the touch screen panels. The most common interface types USB and RS-232. The need for drivers has been eliminated by new HID-compliant touch screen monitors.

• Mounting: Among the various mounting options are included free-standing, rack mount, and panel mount. In case that you want to use free-standing, make sure that you use a heavy-duty stand that was specifically designed for touch screens.

• Environment: For use in a variety of environments, touch screen monitors are available in stainless, standard, and waterproof enclosures.

• Screen size: Sized from 3.5″ to 52″ are available for touch screen monitors. They provide 4:3 or 16:9 aspect ratio.

Your decision to select a certain type of touch screen monitor will be based on various factors, including where it will be mounted, the intended users, type of data to be displayed (text, graphics, video), and the operating environment. Capacitive touch screen monitors can be a great addition to your business if chosen correctly.
