Brightness control with Display Creator

Channels & Functions Tab

The backlight control can be used to adjust the brightness of the display backlight. The brightness value can be configured with a constant value, or assigned the value of a channel.

When using a channel, the channel must be configured in one of the following ways:

• Use a 'float' channel. The channel must have a Quantity of 'unitless' or 'ratio'. 
• For 'unitless', the channel value must be in the range 0.0...100.0 
• For 'ratio' the channel value must be in the range 0.0...1.0 
• Use an Integer or Unsigned Integer channel. The channel value must be in the range 0...100 
• Use a 'bool' channel. When the channel is 'True' the backlight will be on (100%) When the channel is 'False' the backlight will be off (0%) 
• Use an enumerated channel. The numeric value of each enumerated value must be in the range 0...100

 

Note: If a Backlight Control is not included and configured on this tab, then the backlight brightness will always default to 100%.

It can also be used to set the Brightness to a constant value.  If a value of 0% is set the Display will appear to be off after the boot sequence has completed.
