As the world returns to the office – at least to some extent – one of the biggest concerns for companies is ensuring that a given work setup keeps employees safe, connected, happy and effective at work. The look of an office environment can vary greatly, however, there is a growing perception that work is not where you go, but something you do. As a result, work-from-anywhere environments will become increasingly common.
Because of this, touchscreen displays will play an important role in allowing digital collaboration between hybrid teams to continue in a seamless manner. Until a few years ago, touchscreens were bulky devices that were overly complicated and difficult to use. However, the improvement in the accuracy of the touch interface has greatly improved the user experience. You can now use them with your familiar personal touch device.
How a capacitive touch panel works
Capacitive touchscreens consist of glass panels coated with material. The property of this material is that it can store electric charge. So capacitive touch screens basically store charge. Fortunately, the human body can also store electrical charges. So when you touch this screen with your finger, some of the charge on the screen is transferred to your finger. Oscillator circuits located in the corners of the system will then sense this reduction in charge on the screen and figure out exactly where the touch occurred, and transmit this specified information to the touchscreen driver software.
For capacitive touch, the conductive material is sandwiched by the glass and placed on the display. When another electrical conductor, such as a bare fingertip or stylus, touches the surface, the circuit is completed at that location. Sensors embedded in the glass detect where the current is flowing, which is then recorded as a touch event.
The technology behind capacitive touchscreens
Rather than relying on pressure, capacitive touchscreens record input by sensing conductivity—usually from the skin of a fingertip. Capacitive touchscreens are more sensitive than resistive touchscreens because you don’t need to apply pressure. However, since they work by inducing conductivity, you can only use capacitive for objects with conductive properties, ideally including fingertips or special styluses designed with conductive tips.
Advantages of capacitive touch screens
Durability: Often, the display is the most vulnerable part of a handheld device. One advantage of capacitive touchscreens is that they tend to be stronger than resistive touchscreens — especially with heavy use. Heavy users may find that commonly used areas on resistive touchscreens wear out and become unresponsive.
Reliability: If a capacitive touchscreen is punctured or damaged, it may continue to work as usual – think about all the cracked smartphone screens you’ve ever seen people use. The screen may shatter and continue to function. On the other hand, resistive touchscreens usually stop working if any part of the screen is damaged.
This is an important advantage of capacitive touchscreens, as it allows field workers to continue collecting data until they can fix their screens. With resistive touchscreens, field workers may have to forego further data collection until the screen is fixed.
Future-proof: The tech industry is leaning towards capacitive technology, but using capacitive touchscreens on computers will help ensure a smooth and compatible transition to future technologies.
