The principle of non-impact keyboard means that during the keyboard input process, when multiple keys are pressed at the same time, each key can be accurately recognized by the computer without conflict. This is achieved through the control logic inside the keyboard.

Each key inside the keyboard has an independent signal transmission line, when the key is pressed, the corresponding signal transmission line will transmit a signal to the computer's main control chip. In traditional keyboard design, due to the limitations of signal transmission lines, when multiple keys are pressed at the same time, there may be signal conflicts, resulting in the computer can not accurately identify the operation of each key.

To solve this problem, the keyboard without impact uses a special control logic. When a key is pressed, the keyboard sends a scan code to the computer indicating the key that is being pressed. After receiving this scan code, the computer will parse it and perform the appropriate action. In a keyboard-free design, the computer periodically sends a scan code request asking for the current status of the keyboard. Upon receiving the request, the keyboard sends a scan code matrix containing the codes for all keys pressed. The computer recognizes and executes the corresponding operation according to this matrix, so as to achieve the full-key no shock.

The principle of the non-impact keyboard is mainly to improve the control logic inside the keyboard to ensure that when multiple keys are pressed at the same time, each key can be accurately identified by the computer to avoid key conflicts. This design makes the keyboard more smooth in the operation process, and is suitable for scenes that require high speed and accuracy of keyboard operation, such as games and programming.
No impact keyboard adopts matrix key layout, through the combination of the keys into rows and columns, to achieve multiple keys can be pressed at the same time without conflict effect.
When a key is pressed, the keyboard sends the corresponding column information to the computer, which parses this information to identify which key was pressed. The principle of the non-impact keyboard allows the player to press multiple keys without interference, at this time, multiple operations can be achieved at the same time, greatly improving the fluency and accuracy of the game experience.
