2 You can change the Warning and Error settings for 2 parameters:
Backlight and Luminance.
Backlight expresses the relation between the maximum possible
backlight drive and the actual backlight drive. It is an indication of
how much the backlight is aged.
In a display with a new backlight, a certain drive voltage is applied
to the backlight, in order to obtain the calibrated target light output.
As the backlight ages, it becomes less powerful. As a
consequence, a
higher drive voltage must be applied to the
backlight in order to obtain the same calibrated light output.
The drive voltage cannot increase infinitely. It is limited to a certain
maximum. The backlight reserve value indicates how far the actual
drive voltage is away from the maximum drive voltage.
E.g., a backlight reserve of 5% indicates the actual backlight drive
has almost reached the maximum possible value.
Luminance expresses the relation between the actual luminance
and the target luminance in %.
