# Brightness
|
|
|
|
Set the brightness of the [LED screen](/device/screen).
|
|
|
|
```sig
|
|
led.brightness();
|
|
```
|
|
|
|
### Returns
|
|
|
|
* [Number](/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)
|
|
}
|
|
```
|
|
