The keyboard you want to know

The keyboard has a very long history. As early as 1714, various types of typewriters appeared in some European countries. This was the first device to be used for keyboards. Later, the keyboard was not only used on typewriters but also Turing machines and the most primitive computers. IBM’s PC computer appeared, and the computer input device was truly characterized as a keyboard, and it is still today.

"Key layout and quantity"

The keyboard layout and number of keys have also evolved over a long period of time. Today we use the “QWERTY” key design to appear on typewriters in the 1870s. At that time, this design was to slow down the typing speed and prevent the sticks and hammers of two adjacent letters from getting stuck together. Under the effect of “inertia”, this key layout continues today. The number of keys, after the PC computer appeared, as the keyboard was given some new functions (back, desktop keys, etc.), after experiencing 83 keys, 84 keys, 101 keys, and 102 keys, it was standardized as 104/105 keys.

"The working principle of the keyboard"

In the continuous elimination and update of electronic equipment, there have been many keyboard designs with different working principles, and the development history of mechanical, plastic film, capacitive, and conductive rubber types has appeared before and after.

The earliest appearance was a mechanical keyboard, which used a contact spring switch to realize information input through the conduction and disconnection of the contacts; the conductive rubber keyboard appeared later, replacing the metal contact switch with conductive rubber, reducing noise and wear; Plastic film keyboard, internal use of four layers of film to achieve functional use, not only without mechanical wear but also achieve a silent design; static capacitance keyboard, as the current mainstream keyboard design, the biggest advantage is to achieve the keys without impact and high sensitivity.

"The appearance of the keyboard changes"

The keyboard was first integrated with the typewriter, and the keys used circular mechanical shapes. In the PC era, the keyboard has changed from one to an independent presence, and the appearance is a square, angular cuboid shape. With the improvement of aesthetics, practicality, and safety, the appearance of the keyboard has become more rounded and smooth, and the keys are mostly made of flexible plastic materials. The color of the keyboard is no longer rigid. Backlight and marquee elements are also added. These designs enhance the keyboard’s design. Use comfort, reduce the weight of the keyboard, and the appearance is more fashionable.

“Number of keyboard connections”

The keyboard interface standard has also gone through several twists and turns. The first adopted AT (commonly known as “big mouth”). On computers that were not sensitive to use in the 1990s, the transmission efficiency was remarkable; PS/2 (commonly known as “small mouth”) was used in traditional host computers However, with the popularization of notebook computers and USB standards, the improvement of computer performance requires higher keyboard input efficiency. The mainstream keyboard sockets all adopt the USB2.0 standard. Another keyboard connection method is more special, that is, a wireless keyboard, which transmits information and data through infrared rays or radio waves, which is more convenient to use.
