A keyboard is an instruction and data input device used to operate computer equipment, and also refers to a set of functional keys arranged by the system to operate a machine or device (such as a typewriter or computer keyboard). The keyboard is also a part of keyboard instruments and can refer to instruments that use the keyboard, such as the piano, digital piano, or electronic keyboard. The keyboard helps practice typing.The keyboard is the most commonly used and primary input device, which can input English letters, Chinese characters, numbers, punctuation marks, etc. into the computer, and then issue commands and input data to the computer. There are also keyboards with various shortcut keys. With the passage of time, independent products with various shortcut functions are gradually appearing on the market for sale separately, and they come with dedicated drivers and setting software, which can also achieve personalized operations on compatible computers.The shell, some keyboards are fixed to the keyboard panel and base using plastic hidden hooks technology, achieving a metal free screw design, so be careful not to damage them when disassembling.In order to meet the needs of different users, a regular keyboard has three indicator lights: CapsLock (uppercase and lowercase lock), NumLock (numeric keypad lock), and ScrollLock (scroll lock key) (some wireless keyboards have omitted these three indicator lights), indicating the current status of the keyboard. These indicator lights are usually located in the upper right corner of the keyboard, but some keyboards use built-in indicator lights in keycaps, which can more easily determine the current status of the keyboard. However, the process is relatively complex, so most ordinary keyboards do not adopt this design.Disk area, Num numeric keypad area, F-key function keyboard area, control keyboard area, and shortcut keyboard area have been added for multifunctional keyboards.The keyboard circuit board is the control core of the entire keyboard, located inside the keyboard, mainly responsible for key scanning recognition, coding, and transmission interface work.The reverse side of the keycap is visible as the key plunger, which is directly related to the lifespan of the keyboard, and its friction coefficient is directly related to the feel of the keys.There are generally four printing techniques for keycaps: a. ink printing technology, b. laser etching technology, c. secondary forming technology, d. thermal sublimation printing technology.
