We know all about how touch screen kiosks and monitors offer and easily accessible information interface in a
compact form. Touch screen LCD flat panel monitors and LCD PCs are embraced by a vast array of applications looking
to provide easy access. The following eight settings demand quick informational access, which is reason number one
for their success with touch screen monitors.
From retail to transport, with more and more people seeing the
value of touch screen technology, expect to see more touch screens kiosks in these locations:
touch screen kiosks are becoming a hot topic and it's easy to see
why. Retailers are reaping the benefits of having a new channel to sell through. The more points of contact
retailers have with customers the more likely they will buy in-store. And customer aren't complaining either as
each kiosk makes for a better shopping experience by providing easy access to product information and a faster way
to order and pay for goods.
Travel Information and Public Transport
From airports to bus stations, touch screens are quickly becoming
the norm for transport related transactions and processes. Printing and processing tickets is made simple with an
automated machine display, lowering operating costs for public transportation services. Airports are also
benefiting from the use of touch screen machines, which are lowering staffing needs in customs and immigration, and
allowing airlines to simplify the check-in process.
Using a keyboard and mouse for thousands of transactions a day is
hardly efficient. In a busy restaurant, the last thing any employee needs is a cumbersome billing and payment
interface. Touch screen digital signage allows employees to input and process payments significantly more quickly
than a standard PC interface.
Educational and Training Organizations
When it comes to education, the name of the game is quick and easy
access to information. In the early 1990s, computing - and later the internet - revolutionized education. Access to
data became quick, simple, and inexpensive. Now there's a new revolution going on. Offering simple access for
disabled students, attention-grabbing displays for young children, and accessible information for elderly users,
touch screen displays are quickly becoming the most popular means of communicating digital information for
Touch screens have historically been popular in museum displays.
Their ability to convey large amounts of information quickly and easily has made them a fantastic alternative to
the traditional mouse-and-keyboard style PC display. Offering durability, simple access, and slick aesthetics,
touch screen displays are highly popular with museums and public exhibitions.
Touch screens offer more than just simple access to information.
The very design of a mouse and keyboard makes them highly exposed to potential damage or wear. A touch screen,
however, is significantly more durable, able to function even when exposed to dirt and grime. This durability makes
touch screens a worthwhile investment for industrial settings and potentially unclean areas.
With a simple addition from a touch screen kiosk manufacturer, a
business presentation can be supercharged and made significantly more effective. The most effective presentations
demand two things - simplicity and control - and a touch screen display gives business presenters
With the medical world demanding clean and quick access to
information on demand, touch screens are quickly finding a large new audience. From operating theatres to patient
booking rooms, the medical industry is embracing touch screens as a sanitary, ultra-efficient alternative to
traditional PC displays.

AbraxSys explores the inustries utilizing industrial displays with touch screens and how these verticals bennefit from the various touch screen technologies.
Types of Touch Technologies
There are many types of touch screen technology used today –
resistive, capacitive. projected capacitive, infrared and surface acoustic wave.
screen technology, any kind of item can be used to activate
the communication between the hardware’s conductive layers, such as a pen, stylus or finger. These conductive
layers are made up of a normal glass surface topped with two metallic layers, one being resistive and one
conductive, and finally a scratch resistant protective screen encasing it all. What happens when you touch the
screen is that the pressure causes a contact between the resistive and conductive metallic layers, and a change in
the electronic field is monitored. This change is then recorded by the electronic circuitry used in the device and
the data is passed on to the firmware which, in turn, process and then passes 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.).
Multi-Touch Up to 10-Point PCAP Circularly polarized touch panels greatly
enhance display readability in direct sunlight conditions. The touch panels eliminate over 60% of reflected ambient
light while maintaining 79% luminance transmissivity. These resistive
touch panels are designed for use with transmissive LCDs in a variety of portable and stationary outdoor
applications, such as kiosks, navigation systems, industrial instruments, and test instrumentation.
SURFACE CAPACITIVE TOUCH
screen works in a slightly different way to a resistive touch
screen. On top of the monitor glass, a layer is placed that stores an electrical charge. Once the layer is touched,
a very small electrical charge is transmitted to whatever came into contact with the screen, which effectively
reduces the amount of charge on the layer. This change in electrical charge is monitored by sensors which are
located at the corners of the screen. The sensors then pass on the data to the device software and then the
operating system in turn and a visual display is produced. With a capacitive touch screen display, a conductive
input method must be used such as a finger or specific input device.
PROJECTED CAPACITIVE TOUCH PCAP projected
capacitive touch technology is an ideal choice for a wide range of industrial-grade applications, such as
process control terminals, medical displays and agricultural vehicle telemetry systems, as the touch performance in
unaffected by scratches, dirt and dust on the screen. They can also be operated by a user wearing heavy gloves, and
can be sealed to extremely high IP rated systems making them suitable for challenging or outdoor deployments.
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 available for 4,
5, and 8 wire sensors from 5″ to 24.0″.
The complete system depending on the customer-selected outer layer can resist impact, scratches, vandalism, heat,
rain, snow, and ice or harsh cleaning fluids, making it well-suited for outdoor applications.

If you already have a computer system but want to add touch
capabilities, the easiest solution is to purchase an LCD touchmonitor. The touch functionality is already built
Things to think about: • Size. What size display do you want? • Form/factor. Will your touchmonitor be on a desk or countertop, or will it be
contained within a kiosk, a rack, or other enclosure?
(additional guidance) • Color. What case color do you want? Black, dark gray, and beige are the most popular
choices. • Touch technology. We offer a separate introduction to our technologies and guidance
on the best technology for your needs. • Peripherals. Do you want peripherals such as a fingerprint reader, magnetic stripe
reader, or customer display?
Our product pages for LCD
touchmonitors include complete details on these and many other specifications.
When you purchase a touchmonitor, you will need to install the
appropriate driver on your existing computer. Drivers are generally written to match the operating system of the
computer. For example, if your computer is running WIndows XP Professional, you would use the AbraxSys driver
for Windows XP Professional, regardless of whether you have a touchscreen or an LCD. On occasion, drivers are
written to match a certain touch technology rather than the operating system. Also, some peripherals may require
their own, additional drivers.
Add Touch to Your Own
Displays: Buy a Touch Screen with Controller and Driver
If you are an experienced system integrator or OEM, you may wish to
purchase only the basic touchscreen, then integrate it into your own products. You'll need the touchscreen, as well
as its corresponding controller and cables, and a driver suitable for your operating system.
The touchscreen is, literally, the user's first point of contact
with a touch system. It may be a physical film overlaid on top of an LCD that is sensitive to the pressure of a
touch. Or, it may be an grid of invisible waves in front of a display that is interrupted by a finger or other
Things to think about: • Transparency. Do you need 100% of the original display coming through, uninterrupted
by any overlay? Or, can
you accept less transparency because you need an overlay? • Hardiness. Do you need a touchscreen resistant to vandalism? Will your screen be in
a harsh outdoor (rain, snow,
ice ) or demanding indoor (industrial, restaurant kitchen) environment? Some touchscreens are built to
NEMA 4 or IP65 standards. • Touch accuracy. Do you need the precision of signature capture or simply the ability
to record a touch on a large
screen button? • Touch technology. We offer a separate introduction to our technologies and
guidance on the best technology for
your needs. • Size/active touch area. What is the size of the display you are adding touch to, and
do you need a particular size
for the active touch area? • Material. Do you need the touchscreen to be made of glass or acrylic or does it
need particular treatments (heat,
chemical) for additional strength? • Shape. Are you placing the screen over an LCD display?
The controller is hardware that supplies power to the touchscreens,
coordinates the communication between the touchscreen and the computer, and checks for errors.
Things to think about: • Interface. USB or serial? • Mounting. built-in, internal card, external box?
The driver is a software program that enables the touch system to
interact with the computer system. It accepts the data from the controller and does the calculations to move the
cursor on the display in response to a touch. It also screens incoming touch data for errors, controls calibration,
and offers diagnostic and troubleshooting tools.
Drivers are generally written to match the operating system of the
computer. For example, if your computer is running WIndows XP Professional, you would use the Elo driver for
Windows XP Professional, regardless of whether you have a touchscreen or an LCD. On occasion, drivers match a
certain touch technology rather than the operating system.
think about: • Operating system. What is your computer's operating system? • Interface. The appropriate driver may vary, depending upon whether you are using a
USB or serial touch interface. • Download Elo drivers
