What is a Touch Screen?

A Touch Screen is an onscreen input device, which needs to be combined with a display and a PC or other device to make a complete touch input system. The touch screen is generally used as part of a flat LCD monitor, flat plasma monitor or curved CRT monitor. 

Main components

A basic touch screen kit has three main components:

  • touch panel, also called touch sensor or touch membrane
  • controller board or box with cable
  • software driver

Touch Panel

A touch screen panel is a clear glass panel with a touch responsive surface. The touch panel is placed over a display screen so that the responsive area of the panel covers the viewable area of the video screen. There are several different touch screen technologies today - surface wave, resistive analog or capacitive , each using a different method to detect touch input and with various clarity and response advantages. The touch panel generally has an electrical current or sound vibration signal passing through it and touching the screen causes a voltage or signal change. This voltage change is used to determine the location of the touch to the screen. Contact us to decide which technology is for you or Click here for a Guide to choosing the right touch technology.


The controller is a small PC card that connects between the touch panel and the PC. It takes information from the touch panel and translates it into information that the PC can understand. The controller is usually installed inside the monitor for integrated touch monitors or it is housed in a plastic/metal case for external touch add-ons. The controller determines what type of interface (port connection) you will need on the PC. Integrated touch monitors have an additional cable connection on the back for the touch screen. Controllers connect to a USB port or Serial/COM port. Multiple touch screens can be connected using different controllers. Specialised controllers are also available that work with other devices.

Software Driver

The driver is a software update for the PC operating system (Windows, Linux, etc.) that allows the touch screen and computer to work together. It tells the computer's operating system how to interpret the touch information that is sent from the controller. Most touch screen drivers today are mouse-emulation type. This makes touching the screen the same as clicking your mouse at the same location on the screen. This allows the touch screen to work with existing software and allows new applications to be developed without the need for touch screen specific programming. Some equipment such as thin client terminals, DVD players, and specialised computer systems have their own built-in touch screen driver. Separate Software Drivers are available for the various Windows versions - 98/2000/XP or Linux. 

What can you use Touch Screens for?

The touch screen is one of the easiest PC interfaces to use, making it the interface of choice for a wide variety of applications . Some examples of how touch screen input systems are being used today:

Public Information Displays
Customer Self-Service
Point of Sale (POS) for Retail, Restaurant & other locations
Computer Based Training
And many more applications...
The touch screen interface is being used in a wide variety of applications to improve human-computer interaction. Other applications include banking and finance, digital jukeboxes, computerised gaming, voting machines, lottery systems, student registration systems, multimedia software, financial and scientific applications, and more...........

Guide to choosing the right Touch Technology?

Your touch application: Touch Technology:
Outdoor and Harsh use Projected Capacitive Touch Screen (PCT)
Public access applications & others: where maximum image quality is required SAW Surface Wave
Industrial Control IR (Infrared)
Public access applications & others: where maximum image quality is required in a rugged, dusty or vandal risk environment DPWP SAW Surface Wave
Employee related use in industrial, point of sale, medical, transportation use 5W 5-Wire Resistive
When cost is the main factor Four Wire Resistive

PCT Projected Capacitive Harsh use: Outdoor Harsh unattended use
Some Applications
  • ATMs on street
  • Robust Outdoor Public Access Kiosks
  • Public Web phones
  • Harsh Industrial environments
  • Unattended public access applications
  • Cutting Edge Fixed Embedded Technology
  • Unlimited touches life expectancy.
  • Zero moving parts.
  • High Light Transmission- 91%.
  • Durability & Resistance to Vandalism: Shock, Scratch and Vandal resistant.
