A backlit keyboard is a type of keyboard that contains a light underneath the keys, illuminating the letters and symbols on the keys to make them visible in low light environments. The print on the keys is semi-transparent, so the light underneath will shine through it like a window. Most backlit keyboards allow you to adjust the brightness levels, and some also illuminate the tiny space that surrounds the key, which further enhances the visibility of the keyboard. Backlit keyboards are useful for a variety of reasons, including:

• Working in low light environments: Backlit keyboards are helpful when you’re on a red-eye flight or when you’re night traveling by car or train. They give you just enough light to do what you need to do, without disturbing anyone nearby.

• Power outages: If there’s a power outage and you lose electric light, you’ll still be able to type away at your laptop keyboard if it’s backlit.

• Gaming: Backlit keyboards are popular among gamers because they allow you to easily see which keys to press without struggling to see in low light conditions.

• Aesthetics: For those who want a bit more flair in their computer hardware setup, a colorful backlit keyboard is the way to go.

While there is little difference between a backlit keyboard and a standard keyboard, backlit keyboards are more versatile and can be used in low light conditions. However, they consume more power than standard keyboards and can be more expensive.
