Touch Screen Technology and Applications
Touch screens are display screens in which interaction between user and machine is enabled by touching the text and images displayed on the screen. A touch screen is similar to an input device. These screens are used in a variety of applications due to their interactive and user-friendly features.

Touch screen displays are also leased or rented for events and trade shows. Businesses participating in trade shows can keep costs low by opting from touch screen rentals.
Different Types of Touch Screen Technology
Resistive: Resistive touch screen panels consist of one thin layer of conductive material and one layer of resistive material. When a user touches the display screen, a corresponding change in electric current is caused. This is then communicated to the controller and processed. These touch screen panels are quite affordable but do not provide very high levels of clarity and can also suffer damages easily. They resist water and dust very well. Fingers and stylus can be used on these touch screens.
Surface wave: This technology uses ultrasonic waves that keep moving over the screen panel. When a user touches the display screen, a part of the ultrasonic wave is absorbed. This change is communicated to the controller and processed. Surface wave technology is the most advanced touch screen technology but it is susceptible to damage from outside-elements. These screens can be manipulated using fingers and stylus.
Capacitive: Capacitive touch screen panels are coated with a layer that consists of electrical charges. When a user touches the panel, a portion of the charge travels to the contact point on the screen. This charge is measured by circuits placed at the four corners of the panel. The information is then communicated to the controller for processing. These screens can only be manipulated using fingers. They provide very good clarity and are resistive to outside elements.
Different Applications of Touch Screens

The simplicity in using touch screens also contributes to higher productivity among employees.
Training: Due to their user-friendliness, touch screens are used in training programs. People find it easier to understand and learn using touch screens. Touch screens also make the training experience more interactive.
