Full-key rollover means that the computer can recognize multiple keys pressed on the keyboard at the same time.
Full-key rollover adopts a new anti-collision design, which truly realizes the simultaneous pressing of 107 keys of the full keyboard under the USB interface without conflict, and can meet the needs of players for any combination of keys.
The signal of the keys on the membrane keyboard is not that each key has a line to transmit the signal, but several keys use one signal line. Then at this time, if some of these 7 keys are pressed at the same time, a key conflict will occur. Some systems will alarm if there is a key conflict, and some will output one of the keys.
Some game-specific keyboards on the market can better solve the key conflict problem of commonly used keys in games. Key conflicts on ordinary keyboards are inevitable. Some keyboards have 3-4 keys without conflict, and some high-end keyboards can have 7 keys without conflict.
Introduction to CHERRY RK technology with full-key rollover
CHERRY RK technology benefits from the fact that the keys have different voltages on independent rails. When the button is pressed the circuit closes and the controller detects how much current is passing through it. So every key on the keyboard is displayed in real time by the controller.
This means that the keyboard response speed only takes 1 millisecond. Traditional technology takes 20 milliseconds. CHERRY RK technology achieves true full-key rollover and 100% anti-ghosting keys. All buttons can be pressed and displayed at the same time. Single-point triggering can be said to fundamentally solve various problems that can cause button conflicts, button delays and other problems.
RK technology has three major advantages. The signal is read the moment the button is touched. All keys can be pressed and displayed simultaneously. Errors caused by conflicts will no longer exist.
