Comparing the Top 5 Touch Screen Technologies

Touch screens are widely used throughout many daily devices including kiosks, certain vending machines, ATMs, mobile phones, and others. They all use touchscreens to empower the user to collaborate with a computer or device, all without the benefit of a mouse, trackball, joystick or keyboard.

The five most frequently used touchscreens are: 5-wire resistive, projected capacitive, surface capacitive, infrared, and surface acoustical wave (SAW).

5-Wire Resistive

5-wire resistive is the most widely utilized touch technology. A resistive touch screen is made up of conductive layers; a normal optical glass surface covered with two metallic layers, one being resistive and the other conductive, and finally a scratch resistant protective screen covering it all. As the user touches the LCD screen the pressure creates a contact between the resistive and conductive metallic layers. A change in the electronic field is then monitored. This transition is then recorded by the electronic circuitry used within the device and the data is passed on to the firmware which, in turn, processes and then forwards on the data to the devices operating system. The operating system will then produce a visual display on the screen of the captured motion or action (click or mouse drag etc.).

Advantages:

  • Can be activated with virtually any object – finger, stylus, gloved hand, pen, etc.
  • Has tactile feel
  • Lowest cost touch technology
  • Low power consumption
  • Resistant to dust, oil, grease, moisture, and other liquids

Disadvantages:

  • Lower image definition compared to other touch technologies
  • Outer polyester film is vulnerable to damage from scratching, poking, and sharp objects
  • Diffuses the light output of the LCDs backlights

 

Surface Capacitive

This type of touch technology works in a noticeably different way to that of a resistive touch screen. On top of the LCD front window glass, a layer is placed that stores an electrical charge. Once this special layer is touched, a very small electrical charge is transmitted to the finger which came into contact with the screen, effectively reducing the amount of charge on the layer. This change in electrical charge is monitored by touch sensors which are located at the corners of the touch window. The sensors then pass on the data to the device driver software and then on to the operating system and in turn a visual if then display is produced. With a capacitive touch screen display, a conductive input arrangement must be used such as a finger or specific input device.

Advantages:

  • Much better image clarity than resistive touch screens
  • More durable screen than that of the resistive type
  • Excellent resistance to surface contaminants and liquids- dust, oil, grease, water droplets
  • High scratch resistance
  • Does not diffuse the light output of the LCDs backlights

Disadvantages:

  • Requires bare finger or specific capacitive stylus for activation
  • Sensitivity to Electro-Magnetic Interference (EMI) and/or Radio Frequency Interference (RFI)

 

Projected Capacitive

Projected capacitive is similar to surface capacitive, sometimes called PCAP or PCT, is an ideal preference for a wide range of applications, including industrial usage such as process control terminals, medical displays and agricultural vehicle telemetry systems because the touch performance in unaffected by scratches, dust and dirt on the touch window. Compared to surface capacitive technology, PCAP offers two primary advantages: In addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves. For some PCAP windows, they can also be operated by a user wearing heavy gloves, and can be sealed to high ingress protection ratings making them suitable for challenging or outdoor deployments. PCAP also enables multi-touch activation (simultaneous input from two or more fingers). A projected capacitive screen is composed of a sheet of glass with embedded transparent electrode films and an integrated chip which creates a three dimensional electrostatic field. When a finger comes into contact with the screen, the ratios of the electrical currents change, and the computer is able to detect the touch points.

Advantages:

  • Excellent image clarity
  • More resistant to scratching than surface capacitive touch screens
  • Resistant to surface contaminants and liquids- dust, oil, grease, moisture
  • Multi-touch (two-touch)

Disadvantages:

  • Sensitive to EMI/RFI
  • Must be activated via exposed finger, thin surgical or cotton gloves, although some PCAP windows (like those used by AbraxSys) can be triggered by a heavy gloved hand

 

Surface Acoustic Wave (SAW)

SAW touch screen monitors utilize a series of piezoelectric transducers and receivers along the sides of the monitor’s glass plate to create an invisible grid of ultrasonic waves on the surface. When the panel is touched a segment of the wave is absorbed. This enables the receiving transducer to locate the touch-point and send the data to the computer. SAW monitors can be activated by finger, gloved hand, or special mechanical stylus.

Advantages:

  • Excellent image clarity
  • Even better scratch resistance than that of capacitive touch windows
  • Long touch life

Disadvantages:

  • Will not activate with hard items such as a mechanical pen, finger nails or even a credit card
  • Water droplets may cause false-triggering & activation
  • Solid contaminants on the screen can generate non-touch areas until the dirt/dust is removed

 

Infrared Touch (IR)

Infrared touch screen technology does not overlay the LCD display window with an additional screen. Alternatively, infrared displays use IR emitters and receivers to create an invisible grid of light beams across the screen, both horizontally and vertically creating an “X” and “Y” axis. This ensures the best possible image quality since there is no overlaying window on the LCD screen itself. When an object interrupts the invisible infrared light beam, the sensors are able to locate the touch point.

Advantages:

  • Highest image clarity and light transmission of all touch screen technologies
  • Unlimited “touch-life”
  • Impervious to surface scratches

Disadvantages:

  • Accidental activation may occur because infrared beams are actually above the glass surface
  • Dust, oil, or grease buildup on screen or frame could impede light beam causing malfunction
  • Sensitive to water, snow, and rain
  • May be sensitive to ambient light interference
  • Higher cost

So, those are the five most widely touch technologies. Other types do exist, including AbraxSys’ HARDENED ARMORED RESISTIVE TOUCH.

For Armored Touch, a micro-thin sheet of borosilicate glass is laminated to the ITO polyester top sheet used in the typical construction of resistive touch sensors. This process produces a flexible glass membrane which is scratch resistant, water proof and impervious to chemicals, fire and stylus use. The resulting touch sensor is ideally suited to Military, Industrial, Mobile, Public Kiosk and Medical applications. Configurations are from 8.4″ to 24.0″.

Touch Screen for Harsh Industrial Environments

All touch screen interfaces have advantages and disadvantages, depending on their application. For industrial use, typically there are demands, conditions and distinctions that contribute better to certain types of touch screen interfaces.

The most commonly used and possibility most advantageous touch screen technology for harsh duty industrial and automation environments aims to be resistive touch screens. Since resistive touch screens allow the use of gloves and/or mechanical stylus usage, the user will not be bothered with having to remove gloves or protective wear in order to use the device. 

Some industry facilities, like food and beverage for example, require a strict “no exposed glass” policy. Resistive touch technology employs a flexible polycarbonate (in most cases) top-sheet over a glass substrate. Resistive touch screens prevent any exposed glass and allow for usage throughout most industrial applications. 

Many types of touch screen interfaces can excel in many environments, so it’s best to research what the application environment will be, including other project parameters, before selecting the type of touch screen interface that would be ideal for your application.

AbraxSys Begins Migration to Single ITO Projected Capacitive Touch Technology

AbraxSys begins migration to Single ITO Projected Capacitive touch screen technology. The transition will begin with it’s popular 15.6” models. Single ITO Capacitive is noteworthy for its slim border formed with etching technology. The XY electrodes reside on the same glass. The SITO one-glass solution delivers thin and light properties, making it ideal for minimizing the overall weight of the systems.

This SITO technology offers a sensitive, accurate and fast touch response. It can be easily customized to work with a device’s unique bezel and electronic requirements. The touch sensor can be constructed so trace routing is eliminated from up to three sides causing an increased touch area and expanded area for application development. SITO can also be bonded and co-molded to a plastic bezel for unique finish looks and styling. The touch electronics consisting of analog and microprocessor chips with firmware, can be easily integrated and implemented into a large variety of applications.

Single-Layer Projected Capacitive Features and Benefits:
• Light-touch operation.
• Low power usage
• Lower cost vs two- and three–layer projected capacitive touch screens
• Multi-touch supporting up to 10 points. Supports gestures such as flicking and zooming.
• Glove-operation available
• High transparency delivers a clear display appearance.
• Operates when glass is scratched or broken
• A stylish flat interface is available with the covering glass / covering acrylic options.
• No touch screen parts physically moves at detection. Functional degradation rarely occurs even towards the end of product life.
• Projected capacitive touch screens are tough, weather-resistant, and their functionality is not affected by ultraviolet radiation.

AbraxSys is Increasing the Performance Level of it’s 15” and 15.6” LED Displays with IPS Technology

AbraxSys announced today that it is increasing the performance level of its entire line of 15” (4:3) and 15.6” (16:10) LED-backlit LCD products to utilize In-Plane Switching technology. This is a major move to vastly increase the viewing angles of our 15” and 15.6” LCDs and continue offering the highest performing rugged LCD technology. The full transition is slated to take place late second quarter 2015.

In-Plane Switching (IPS) was one of the first significant improvements in the light-transmissive characteristics of TFT panels. Co-developed by Hosiden and NEC, IPS technology solves two main issues of a standard twisted nematic (TN) TFT display: Color and viewing angle.

IPS Technology

With IPS, the crystals are horizontally aligned across the screen rather than vertically, and the electrical field is applied between each end of the crystal molecules creating a lateral electric field. In this way, the crystals are kept parallel to the the electrode pair, which is parallel to the glass substrate of the screen. The liquid crystal molecules are not anchored to the lower glass substrate, therefore they resolve quickly into the desired alignment.

In a TN TFT display when one end of the liquid crystal is adhered to the lower glass substrate and a voltage is applied, the crystal compounds uncoil, altering the angle of polarization of the transmitted light. A downside of basic Twisted Nematic technology is that the alignment of liquid crystal molecules changes the further away from the anchored electrode, turning at right angles to the substrates. This degrades the flow of light causing diminishing contrast, impaired brightness and altering color definition at wider angles to the screen. IPS vastly improves viewing angles of TFT monitors.

AbraxSys Implements New Dry Optical Bonding Technology

AbraxSys has begun implementing latest optical bonding process technology called “Dry Bonding”. This brand-new dry vacuum bonding will replace the current standard of “wet bonding” technology. Dry bonding utilizes production jigs and is fully automated making it very stable in yield and precision. This is particularly important for smaller size TFT LCDs.

dry bondLiquid optical bonding technology (“wet” bonding) was developed for LCDs in late 1970’s. In spite of its challenges, it is still the current standard of optical bonding technology. The bonding material involves many ingredients but typically these materials are purchased as a two-part thermal cured chemistry. In a two-part system, the materials must be thoroughly mixed in prescribed ratios of the “wet” agents and de-aired. Great care must be taken so that all pockets of air and gas, generated due to mixing or chemical interactions, are eradicated and then filtered to minimize the existence of any foriegn substances. Liquid optical bonding is typically labor intensive with long cycle times.

During the curing of 2-part chemicals in “wet bonding”, considerable shrinkage may occur which makes it challenging to precisely control the bond-line. Many liquid adhesives, especially silicone apply a primer material to achieve sufficient adhesion to many low surface energy substrates. Additionally, the clean-up of the display panel and tooling are required after lamination, increasing the cycle time, material and solvent cost, equipment cost, and can further yield loss.

drybond-airgap

Dry film bonding applies flexible substrates and optical films to the rigid LCD substrates by using pressure sensitive adhesion. The dry bonding process positions a tack-free sheet material next to one substrate and then is mechanically assembled to a second substrate. The whole assembly is then vacuum sealed and further exposed to pressure and temperature in compliance with a prescribed recipe.

There are multiple advantages to dry bonding over wet optical bonding.

1. Dry bonding is much cleaner and faster because the LCD is laminated without residuals to remove after bonding and the tooling remains ready for immediate re-use.
2. The process is dimensionally superior because it does not require allowing for shrinkage, bond-line control, or varying cure rates that can change the bond-line and create internal stress.
3. There is no wastage of raw materials. Cleaning solvents are not necessary.
4. The process is much faster due to fewer steps, little clean up, and less equipment. It can be completed in under 30 minutes, whereas “wet” bonding needs to cure following the bonding process for typically 3 days.
5. Since the materials are solid, full automation is achievable.
6. Dry film bonding produces high yield and is repairable, which is not the case with many liquid optical bonding technologies.
7. Dry bonding is more stable up to altitudes over 100,000 ft (30,000+ meters). Most liquid bonded stacks begin deteriorating just over 40,000 ft, (12,000 meters) at least temporarily.
8. Easily add additional layers of optical substrates to increase resistance to boot-kick or ballistic applications.
9. Typically has lower deflection amplitude at resonance than liquid bonded displays. Also has higher resonance frequency.
