All about touchscreens

The touch screen has made life and work easier for many modern organizations. When choosing an industrial touch screen there are different touch technologies to consider. Technologies used most today are resistive, wired projected capacitive and ITO projected capacitive touch screen technology.

What is the difference between the different touch technologies? Compare them below.

Have you considered this for your touch solution?

Multi touch

Multi touch is a touch screen technology that recognizes when a display is being touched at more than one point. This touch technology enables more functions like pinch to zoom.

A multi touch display also gives users the opportunity to use the screen with more than one person at a time. This interactivity makes it more flexible in use and makes working together easy.

A multi touch display can be used to write, draw, sketch and brainstorm using different touch objects.

Protective glass & polarizers

Cover glasses and polarizers for a touch screen come in a variety of sizes and differ in thickness. Choose thermally hardened glass for extra protection. Use it to vandal-proof your screen application in outdoor environments. Or add special polarizers that make the screen anti reflective or anti glare. Great when a display is used in direct sunlight.

Other touchscreen technologies

Infra red touchscreens

A solution based on the infrared touch technology offers suberb image clarity. The original image quality is preserved because there is no film in front of the display.

After a simple installation, the touch screen can be operated with either a finger, gloved finger or a pen. An infrared touch display can be scaled in size up to 150 inch in diagonal.

SAW touchscreens

As the name might suggest, a surface acoustic wave (or SAW) touch screen uses sound waves. The sound waves are conducted over a perfectly smooth glass surface. A touch event is registered when the sound waves are absorbed by a touching fingertip..

The SAW touch screen technology uses clear glass, which guarantees a high quality image and a good protection against chemical substances. Because a surface acoustic wave touch display doesn’t use electrically conductive surfaces, the chance of damage or wear is minimal.

Optical imaging touchscreens

An optical imaging touch screen uses multiple optical sensors that detect a touch point. The touch is registered right before the actual physical contact with the screen is made.

For users this means they can apply minimum pressure to the screen to create a response. And they can use any input device such as a finger (with and without glove), pen or stylus.

Because the optical touch technology does not use a coating overlaying the touch screen, it gives out a crystal clear image. Next to that, scratches don’t effect the screen operation. This makes it very suitable for use in demanding public environments.
