What Is Keyboard Backlighting?

A keyboard backlight is a series of lights that illuminate your keypad when typing. They have been included as a feature on mechanical and membrane keyboards for a long time. But to this day, it remains a technology that continues to evolve.

Insider Tip

Disable the keyboard backlight if you need to preserve your computer’s battery life.

Traditional Backlit Keyboards

For many built-in or standard standalone keyboards with PCs and Macs, the light source consists of a handful of small LED lights that switch on whenever a key is pressed.

Depending on the model, you might be able to control the brightness levels. And on others, you may only get one brightness setting. The traditional backlight is excellent for those who need to work in dark environments, on planes, or on public transport.

However, the standard keyboard backlight has evolved recently to include multicolor and RGB technology.

Multicolor Backlit Keyboards

These models take keyboard illumination to the next level by increasing the number of lights and colors behind the keys. They also come with presets to change the patterns of how the lights flicker and glow.

RGB Keyboards

RGB keyboards feature a multicolor light behind each key. They often come with highly customizable software systems which allow users to tailor each key and its effects precisely as they see fit.

Warning

Don’t assume that a new laptop automatically comes with internal lighting. While many do, this is a spec you should verify before purchasing.

RGBs are often seen as the best-backlit keyboards for gamers because the lights are programmable in highly technical ways. For example, they can alert users if there’s a poor wireless connection or the computer is at risk of overheating.
