description:
|
|
Backlight devices provide backlight for different types of graphical
|
|
displays. They are typically but not necessarily implemented using a white
|
|
LED powered by a boost converter.

|
properties:
|
|
default-brightness:
|
|
description:
|
|
The default brightness that should be applied to the LED by the operating
|
|
system on start-up. The brightness should not exceed the brightness the
|
|
LED can provide.

|
|
|
|
max-brightness:
|
|
description:
|
|
Normally the maximum brightness is determined by the hardware and this
|
|
property is not required. This property is used to put a software limit
|
|
on the brightness apart from what the driver says, as it could happen
|
|
that a LED can be made so bright that it gets damaged or causes damage
|
|
due to restrictions in a specific system, such as mounting conditions.
