Beginner’s Guide to Industrial Touch Screen Monitors

Industrial touch screen monitors are often referred to as open frame touch screen displays or open-frame monitors. The unit typically consists of a metal frame that contains the monitor’s internals and LCD screen without the use of a housing or bezel. A critical feature of industrial touch screen displays is that they are constructed entirely of industrial-grade materials, which usually last much longer and are far more rugged than consumer-grade devices. 

What are the Applications of a Touch Screen Monitor for Industrial Use?

Industrial touch screen monitors are designed for heavy-duty devices and constant use by staff or the general public, such as in CNC machines for commercial use. Industrial touch screen displays are continually put to the test in these settings, where they must withstand harsh operating conditions in order to remain functional.

An interactive kiosk is another example of industrial touch screens that can be used in a harsh environment. Industrial-grade touch screen displays are built into kiosks to withstand continuous human use. A touch screen display for commercial use is mainly employed to control more comprehensive workstations.

Different Types of Touch Screens

Contact panel technologies such as 5-wire resistive, projected capacitive, surface acoustic wave (SAW), surface capacitive, and infrared are all unique. Below, we will discuss each of these in greater detail, along with their distinguishing characteristics and advantages.

5-wire Resistive

This touch technology is the most widely adopted form of modern touch technology. A resistive touch screen is made up of a film screen and a glass panel sandwiched together by a thin metallic panel with a minimal gap in between. When you touch the screen, two metallic frames maintain contact, generating an electric current that informs the unit of the point of contact. 

One of its main benefits is that it can be operated by any object, including fingers, a pencil, a stylus, or a gloved hand. Its only requirement is a precise pressure point on the screen. Another advantage of this technology is its low cost and power usage. Additionally, 5-wire resistive screens are completely protected against liquids and substances on the board, such as moisture, dirt, grease, and oil. 

The main disadvantages of this technology include inferior picture consistency, and the vulnerability of the polyester coating that protects the sensor to damage or being scratched by sharp items.

Surface Capacitive

Another commonly used contact technology is surface capacitive, which consists of a glass plate sandwiched between a translucent electrode layer and a protective shield or cover. Surface capacitive displays are powered and operated by the static electricity produced by the human body. Therefore, this touch interface can only be used with a finger or a stylus pen that carries an electrical charge. 

The benefit of surface capacitive touch design over 5-wire resistive touch is that it provides consumers with a higher picture consistency. The film is usually more durable and offers outstanding resistance to sweat, grease, and dust, while also offering a good level of scratch resistance. 

The possible disadvantage of surface capacitive is that it must be powered with a bare finger or capacitive stylus, which may be inconvenient in conditions where gloves are needed, such as medical health centres and restaurant kitchens.

Projected Capacitive Touch

Multi-touch activation is a characteristic of projected capacitive touch screen devices that allows for simultaneous feedback from several outlets. A projected capacitive touch screen consists of an integrated circuit chip and a transparent electrode layer enclosed in a glass panel. This produces a three-dimensional electrostatic field that is triggered when a finger makes contact only with the screen, enabling the computer to establish the exact position of the contact points.

Some of the main benefits of projected capacitive touch technology are its excellent picture quality, as well as itsis being impervious to liquids and other surface pollutants, and much less prone to nicks and scratches than surface capacitive displays. Additionally, one of the most significant advantages of this touch system is its multi-touch capability.

The main disadvantage of projected capacitive touch technology is that it can only be activated with a bare finger or with medical or thin cotton gloves. Additionally, it is vulnerable to electromagnetic and radio-frequency interference (EMI/RFI).

Surface Acoustic Waves (SAW)

SAW contact technology utilizes a collection of piezoelectric materials (devices that transform pressure differences to electric signals) and receivers around the screen’s perimeter. This results in the formation of an unseen field of electromagnetic waves on the panel’s surface, which is absorbed in the point of contact. This informs the system of the contact location on the phone, which is then sent to the machine.

One of the best things about SAW contact technology is that it can be interfaced with almost anything, whether it is bare skin or a tightly gloved finger, which gives it an advantage over any other existing touch technologies. Additionally, surface acoustic wave displays have superior illumination, picture resolution, and scratch resistance. Additionally, SAW displays are straightforward to use, and that is why this specific system is commonly used by manufacturers of high-end touch monitors.The disadvantages of SAW include the inability to control it with rough objects such as a fingertip, pen, or credit card, but this is a minor downside. Additionally, the screen must be kept clean because accumulation of solid particles may result in unresponsive areas. Moreover, the presence of water droplets can also result in false activations, which is especially inconvenient for use in work environments such as restaurants, cafes, and bars.

Infrared (IR) Technology

Infrared (IR) displays project an invisible stream of light beams around the screen using IR receivers and emitters. This eliminates a need for a protective film or covers over the display, resulting in the highest picture brightness and accuracy possible. When an entity approaches the display, the infrared beams are disrupted, and the sensors inform the machine of the orientation of any contact points.

One of the main benefits of infrared contact technology is that it provides unmatched vibrancy and picture accuracy. It is, in fact, the finest of all touch technologies. It has an endless “touch-life” and is fully resistant to surface scratching.

However, there are also a few drawbacks of IR technology to consider. Due to its high sensitivity, a build-up of grease, dust, or oils on the screen may cause it to fail. These displays, which are at the high end of the price range, are also not waterproof and may not function adequately if they come into contact with moisture. In addition, they can also be vulnerable to ambient light interference.

Conclusion

Thanks to their fast processing speed, touch screens boast improved performance. Additionally, touch screens provide consumers with intuitive interaction. Finally, touch screen technology is simplistic and allows direct interfacing, rather than relying on peripherals such as a mouse and keyboard.
