Implementations

impl Backlight

pub async fn without_display_power() -> Result<Self, Error>

Creates a simple Backlight control, for devices on which DDIC power cannot be switched off and on.

pub async fn with_display_power( power_off_delay_millis: u16, power_on_delay_millis: u16, ) -> Result<Self, Error>

Creates a Backlight control that manages both the backlight brightness/power and the power state of the DDIC.

pub async fn get_max_absolute_brightness(&self) -> Result<f64, Error>
