This is not uncommon for ccfl tubes (same technology as the new energy
efficient light bulbs replacing incandescents these days). It's more
pronounced with the room temperature is cooler and as the display
ages. They work very much like fluorescent light bulbs - they get
brighter as they warm up. If your display is under warranty I would
talk to the manufacturer and see if this is covered and if so consider
having it replaced. I would expect this on a cheap brand display but
not on an Apple screen.

I was working in my garage today and the shop lights take a good 10
min to reach full brightness in this cold weather. Same concept.
