panel Dimmer

Hi All,

I have incandescent lights in my homebuilt panel and LCD displayse in
avonics. What type of dimmer is needed for these components, and will one
work equally well for the lights and the LCD's or would it be better for the
LCD's to have their own. Then, what is the way to go for the least amount
of hassel? I am far more intrested in the contrast adjustment of the
avonics than the control of the lights. Is one control suitable for three
different LCD displays?
