What is a capacitive keyboard? How about a static capacitance keyboard?

The static capacitance keyboard is a kind of computer keyboard, and its existence history is very long. The static capacitance keyboard already exists before the membrane keyboard is available. So what is a capacitive keyboard? How about a static capacitance keyboard? Let's take a look at the decoration home decoration network Xiaobian.

What is a capacitive keyboard?

The capacitive keyboard, the English name Capacitive Keyboard , is a type of keyboard, from the trigger principle. The static capacitance keyboard uses the change of the capacitance capacity to judge the opening and closing of the button. After the button is pressed, the capacitance of the switch changes, thereby triggering, and the whole process does not require the closing of the switch. It is precisely because there is no physical contact point that tapping can be achieved, resulting in less wear and longer service life. More stable, fast, full-key conflict-free, extremely sensitive. It is often seen on large medical devices as a relatively expensive high-end gaming peripheral.

What is the principle of a capacitive keyboard?

The static capacitance keyboard uses the change of the capacitance capacity to judge the opening and closing of the button. After the button is pressed, the air capacitance capacity in the conductive glue changes, thereby triggering, and the tapping action can be realized without the physical contact point in the whole process. According to the way of detecting and controlling the capacitance change, it can be divided into a parallel trigger structure and a vertical trigger structure.

Parallel type: The two electrodes are horizontally and horizontally. With the spring structure installed in the keycap, the distance between the two electrodes will change as the spring moves up and down during the tapping process , thereby detecting the change of the capacitance value.

Vertical type: It adopts two electrodes which are vertical and vertical, and there is no spring structure in the key cap. The capacitance value is directly changed by the thickness change of the air layer in the longitudinal gap during the tapping process, thereby judging the key value.

How about a static capacitance keyboard?

The capacitive keyboard has become a special favorite of a small number of people under the double impact of the membrane keyboard and the mechanical keyboard. After all, the feel is not much different from the membrane keyboard, and the price is very expensive. Most users won't choose to buy, and even many people don't know there is a capacitive keyboard. But the static capacitance keyboard still exists, and his way of existence is beyond everyone's imagination. Instead of relying on some people's pity for the static capacitive keyboard to earn some sales, he has embarked on a high-end route.

Secondly, the electrostatic capacitor keyboard is quite high on the manufacturer's technical requirements. Especially after the manufacturer's improvement of the bowl-shaped silicone structure inside the keyboard, it is no longer a separate rely on silica gel to complete the control of the opponent's sense, but in the bowl of silica gel. A soft spring is added inside to ensure that the static capacitance keyboard can provide users with a more comfortable and comfortable feel.

In addition, after adding the spring, the manufacturer can also better control the hand feeling, which also makes the static capacitance keyboard have the most unique partition pressure design. This is a very unique ergonomics, according to the size of the user's finger pressing force, let The keyboard is divided into multiple parts, and the trigger pressure of different parts is also different. It can be said that the feel experience brought by people is very unique.

There is also the work of the keyboard, as we all know, manufacturers have been pursuing the ultimate in product work. A variety of technologies are piled on the keyboard, what sublimation technology, PBT keycaps, etc., as well as a variety of small details, so that you first feel the identity of the keyboard at first sight Grade.

The above is what Xiaobian brought to you. What is a capacitive keyboard? How about a static capacitance keyboard? I believe that everyone has a basic understanding of what is a capacitive keyboard after reading this article.
