# Brightness
Set the brightness of the [LED screen](/microbit/device/screen).
```sig
led.brightness();
```
### Returns
* [Number](/microbit/reference/types/number) - returns the LCD screen brightness as a number from 0 to 255. A return value of 255 means the screen brightness is at 100% and 127 is about 50% brightness.
### Example: maximum brightness
If the screen brightness is < 100%, the following code sets the brightness to 100% (255):
```blocks
if (led.brightness() < 255) {
led.setBrightness(255)
}
```
