Lcd Backlight

Lcd backlight?
i have a 27 lcd tv and theres this button that powers off its back light so when i push it what happens is the screen will go black (like its turned off) but i can still hear the television program..what is this function for???
Saving power and reducing the wear on the back light when you still want to hear the TV program but are not watching the TV.
Probably really good for music choice channels on cable.
