# Enable
|
||
|
||
Turns the LED screen on and off
|
||
|
||
```sig
|
||
led.enable(false);
|
||
```
|
||
|
||
## Parameters
|
||
|
||
* ``on`` is a [boolean](/types/boolean) that defines the on/off state of the screen
|
||
|
||
## Example: Turning off the screen
|
||
|
||
This program turns off the screen when pressing button ``B``
|
||
|
||
```blocks
|
||
input.onButtonEvent(Button.B, ButtonEvent.Click, () => {
|
||
led.enable(false)
|
||
});
|
||
```
|
||
|
||
## Pins: P3, P4, P6, P7, P9, P10
|
||
|
||
These pins are coupled to the LED matrix display, and also it’s associated ambient light sensing mode.
|
||
To disable the display driver feature (which will automatically disable the light sensing feature) call the DAL function ``led.enable(false)``.
|
||
To turn the display driver back on again later, call ``led.enable(true)``.
