A Touch Screen is a
computer display screen that is sensitive to human touch, allowing a user to
interact with the computer by touching pictures or words on the screen. Global Demand For
Touch Panel Technologies (Human Touch Interface Into An Ever Widening Array Of
Integrated IT Systems) Is Projected To Grow Exponentially Over The Next
Decade. Integrated global infrastructure will rely more and more heavily
on human touch interface into production, logistics, and retail systems via
touch panel displays. Within our daily lives, touch interface with the
systems that we employ to interact with our "digital world" will
require the application of touch panel use to grow into ever more varied and
integrated applications.
There are three types of touch screen
technology:
Resistive: A
resistive touch screen panel is coated with a thin metallic electrically
conductive and resistive layer that causes a change in the electrical current
which is registered as a touch event and sent to the controller for processing.
Resistive touch screen panels are generally more affordable but offer only 75%
clarity and the layer can be damaged by sharp objects. Resistive touch screen
panels are not affected by outside elements such as dust or water.
Surface
wave: Surface wave technology
uses ultrasonic waves that pass over the touch screen panel. When the panel is
touched, a portion of the wave is absorbed. This change in the ultrasonic waves
registers the position of the touch event and sends this information to the
controller for processing. Surface wave touch screen panels are the most
advanced of the three types, but they can be damaged by outside elements.
Capacitive: A capacitive touch screen panel is coated with
a material that stores electrical charges. When the panel is touched, a small
amount of charge is drawn to the point of contact. Circuits located at each
corner of the panel measure the charge and send the information to the
controller for processing. Capacitive touch screen panels must be touched with
a finger unlike resistive and surface wave panels that can use fingers and
stylus. Capacitive touch screens are not affected by outside elements and have
high clarity.

Data
capture equipment, bar code scanners, and wireless communications
devices (PDA & Smartphones) increasingly employ human touch
interface displays.
Corporations and consumers invest billions of dollars each year in such equipment.
Daily use, or miss use, of such equipment wears out and or damages the touch panel screens used in these devices.
Servicing
equipment with the manufacturer can often be costly. Many companies
prefer to refurbish devices (replace the touch panels) by contracting
with 3rd party repair companies, or by doing the work "in house".
As
well, used devices are collected, repaired, and sold as refurbished
stock to consumers seeking a lower cost option to brad new equipment.
Here too replacement touch panels are in demand.
But
sourceing supply of the exact touch panels needed to service a given
inventory of equipment can be difficult. Factory To Customer's
complete design, prototype, and managed production services can
reliably deliver the exact touch panels needed, and do so at a
competitive price.

P.O.S.
(point of sale) equipment technologies are used globally to provide
human integration into the the IT platforms that increasingly manage
the daily retail commerce of our planet.
Restaurants, Bars,
Hotels, Convenience Stores, Retail Check out kiosks, etc. employ touch
panel interfaces into invoicing and inventory management platforms.
Hundreds
of millions of new equipment installations occur annually, hundreds of
millions more units need servicing annually. Inventory supplies of
the exact touch panels needed for a given application are limited, and
often not available on the open market.
