Abstract
Description
Technical Field
[0001] The present invention belongs to the field of keyboards, and in particular relates to a mechanical keyboard using NFC as a key. Background Art
[0002] A keyboard is a device used to input commands and data for operating computer equipment. A mechanical keyboard is a type of keyboard. Structurally, each key on a mechanical keyboard has a separate switch to control its activation. This switch is also called a "switch." Mechanical keyboards are categorized by microswitch types, including traditional brown, blue, white, black, and red switches, as well as Romer-G and optical switches. Because each key has a separate microswitch, the keystrokes have a strong click feel, creating a unique feel ideal for gaming. This is why they are often found in more expensive high-end gaming peripherals.
[0003] Traditional mechanical keyboards use mechanical switches or optical switches as the switch-on keys. The keys are not stable enough when pressed, and there is a friction feeling when they rebound, which makes them less practical. In addition, the backlight of traditional mechanical keyboards is mostly concentrated on the keycaps, and is displayed through laser-engraved characters. The lighting effect is poor, and the practicality is greatly reduced. Summary of the Invention
