The Structure Of The Keyboard

The keyboard shell and some keyboards are fixed to the keyboard panel and base using plastic concealed hooks. This technology enables a metal-free, screwless design, so exercise caution during disassembly to avoid damage.

To meet the needs of different users, conventional keyboards typically include three indicator lights: Caps Lock (letter case lock), Num Lock (numeric keypad lock), and Scroll Lock (scroll lock key). Some wireless keyboards omit these indicators. These lights display the keyboard's current state and are usually located in the upper right corner of the keyboard. However, some keyboards use built-in indicator lights on the keycaps, which make it easier to monitor the keyboard's status. This design is relatively complex, so most standard keyboards do not incorporate it.

Keyboards generally consist of the following areas:

• Panel area
• Numeric (Num) auxiliary keypad area
• Function (F key) area
• Control key area
• Shortcut key area for multifunctional keyboards

The keyboard circuit board serves as the control core of the entire device. Located inside the keyboard, it handles key scanning, recognition, encoding, and transmission via the interface.

On the reverse side of each keycap is the key plunger, which directly affects the keyboard's lifespan. Its friction coefficient also determines the tactile feel of the keys.

Keycap printing technologies generally fall into four categories:
a. Ink printing technology
b. Laser etching technology
c. Secondary molding technology
d. Sublimation printing technology
