How to determine what LCD panel is inside my T60?

[justthinking]

Other than open up the casing and look for FRU number, is there another way to determine what LCD panel is inside my T60?

I noticed that T60's LCD screen is a lot colder (bluish) compare to my T23 with Hitaichi panel.

It's easy to check keyboard, memory, optical drive, and hdd.
But it seems like a lot more compliated if you want to find the FRU for LCD.
