Capacitive is the world’s leading touchscreen technology. Research shows that over nine in 10 of all touchscreens produced and shipped globally consist of capacitive touchscreens. There are several types of capacitive touchscreens, however, one of the most popular being projected. For a better understanding of projected capacitive touchscreens, keep reading.
What Is a Projected Capacitive Touchscreen?
A projected capacitive touchscreen is a type of capacitive touchscreen device that’s more accurate and responsive than other capacitive touchscreens.
All capacitive touchscreens use capacitance to detect touch commands. When you turn on a capacitive touchscreen — including a projected capacitive touchscreen — an electrostatic field will be emitted across the display interface. The capacitive touchscreen will then measure the voltage of this electrostatic field while looking for changes. Touching the display interface will cause the voltage to change, thereby allowing the capacitive touchscreen to identify your touch command.
Projected capacitive touchscreens use this same method to detect touch commands. The difference is that they feature intelligence processing. Intelligence processing improves the responsiveness and accuracy of projected capacitive touchscreens.
Benefits of Projected Capacitive Touchscreens
Why should you choose a projected capacitive touchscreen? For starters, they require very little pressure to perform touch commands. You won’t have to press your finger forcefully against the display interface. On the contrary, just hovering your finger directly over the display interface is often enough to trigger a touch command.
As previously mentioned, projected capacitive touchscreens are highly accurate. Thanks to their use of intelligence processing, they can pinpoint the location of a touch command more accurately than other touchscreens.
Projected capacitive touchscreens are also durable. Most of them, in fact, last longer than other types of touchscreens, such as resistive touchscreens. This is because projected capacitive touchscreens, like all capacitive touchscreens, don’t feature moving parts. They use a non-mechanical method of operation that involves an electrostatic field. As a result, performing touch commands won’t wear down a projected capacitive touchscreen.
Projected capacitive touchscreens don’t suffer from ghost touch commands. Ghost touch commands often occur when a touchscreen is exposed to an object. If you’re carrying a touchscreen in your pocket, for instance, it may trigger a ghost touch command. Projected capacitive touchscreens don’t suffer from ghost touch commands such as this.
It’s also worth mentioning that projected capacitive touchscreens offer excellent image clarity. The top layer is typically made of glass. In the rear of a projected capacitive touchscreen is a backlighting system that will illuminate the pixels. With its glass layer, images appear clearer and more detailed.
