When to Choose a Capacitive Touchscreen

Any device that utilizes touch gestures like swiping, pinching, or multi-touch will require a capacitive touchscreen. These features often help make capacitive touchscreen displays more intuitive and user-friendly than resistive touchscreens. Capacitive touchscreens are best suited for applications requiring improved touch responsiveness with better image brightness and contrast.

Resistive Touchscreen Displays

Resistive touchscreen panels sense pressure on the display's top layer and send a signal to the circuit layer to activate the touchscreen functionality. Because they use pressure to activate the touch inputs, resistive touchscreen displays can be used with a stylus, gloves, and other items. Resistive touchscreens are built without cover glass and made of plastic, making them more susceptible to dents and scratches.

Resistive touch panels were the original touchscreen to enter the market and are still widely used.

How do resistive touchscreens work?

Resistive touchscreens are made of two resistive coating layers with a gap or space layer between them. A "touch event" occurs when these two layers make contact with each other (closing the circuit) by the user's action of pressing into the soft, semi-flexible top layer. Each layer consists of horizontal and vertical lines (x,y matrix) that detects the exact location of the touch.

The gap or space layer typically consists of air or inert gas and some spacers whose only purpose is to separate the soft top layer from the bottom layer.

Resistive touchscreens will not respond to accidental inputs from the environment, so they won&#;t be interrupted by things like water spills or lightweight debris landing on the screen.

This type of touchscreen requires more intentional inputs from the user, making them more reliable in rugged and unstable environments. For example, a resistive touchscreen is the perfect solution on a construction site where water or debris might land on the screen. They&#;re also the best touchscreen display option for situations where the user is wearing gloves.

Resistive Touchscreen Disadvantages

Resistive touchscreen panels are unfortunately more susceptible to dents and scratches. Their poor visibility in direct sunlight does not make them ideal for outdoor applications. Their inability to respond to multi-touch inputs can be a disadvantage in fast-paced applications requiring such. Because resistive touchscreens rely on the pressure applied to the top layer, they tend to be abused and mishandled, which makes them less durable over time than capacitive touchscreens.
