Resistive Touchscreens vs Capacitive Touchscreens

Resistive vs capacitive touchscreens

Resistive Touchscreens

So what is a resistive touchscreen?

Well, firstly they are everywhere you go. You use them day to day without realising and examples of this include ATM machines, mobile phones and tablets. They are also found in medical and automation equipment. So how does it work?

In simple terms, Resistive Touchscreens rely on resistance. This means that the pressure you apply causes the screen to respond to that pressure. Resistive touchscreens are built from two layers of material with a gap between them. These layers both have a coating on one side. When you push on the outer screen the two layers of coating press against each other and a voltage is passed through, meaning it is then processed as a touch in that position.  Since this process is based on pressure, it can be used by any object including gloved fingers, a stylus or even a fingernail.

Today Resistive technology is a mature and well-known technology. Resistive technology has been available within the SCHURTER group for nearly 20 years. SCHURTER has built upon extensive knowledge of resistive technology, the manufacturing of the products and the materials used. As a result of this SCHURTER can help you to fulfil your needs.

Capacitive Touchscreens

What is capacitive technology?

Capacitive touchscreens are found across both the industrial and consumer markets, an example of the consumer market would be the iPhone. Capacitive touchscreens rely on the touch of a conductive object which can be as simple as just your finger. Capacitive touchscreens are highly responsive. This is because they do not depend on pressure to register a touch so that even the slightest contact will activate the screen. A capacitive screen is usually made of one insulating layer, such as glass, which is coated with a transparent conductive material on the inside.

Capacitive touchscreens can use glass as the front panel, this makes them hard-wearing, resistant to scratches and easy to clean. The screens are also more sensitive and precise with a much sharper display and a better overall look due to there being only one layer instead of several. Capacitive touchscreens can also implement multi-touch gestures, allowing you zoom in and drag.

The only downside to using a capacitive touchscreen is that you need to touch with an item that has a capacitive charge. So for example, if you were to use a pair of gloves then the touchscreen would not respond.

We at SCHURTER offer capacitive touchscreen solutions for business across many industries ranging from Building Equipment to Agriculture and Forestry.
