Details
This command changes the light output of the front panel when a test requires different instrument
illumination levels.
The change in illumination is temporary. The normal backlight settings are restored after a power
cycle. You can use this to reset a display that is already dimmed by the front-panel Backlight Dimmer.
Screen life is affected by how long the screen is on at full brightness. The higher the brightness
setting and the longer the screen is bright, the shorter the screen life.
Example
display.lightstate = display.STATE_LCD_50
