Laptop LCD - Any good?

[things]

Hey guys,
I recently ripped apart a old laptop, simply because its too old to do anything useful. I also have the LCD, compltely intact, with its own circuit board still on. I was wondering on ways i could possibly drive it. As i said, all the electronics that are mounted to the LCD itself are still there, its just missing the rest of the computer xD I searched on google for the part no., and i got results, but not the ones i wanted.

Thanks

Unfortunately with laptops much of the circuitry for driving the LCD is on the main board, so they aren't very useful.

If the cold cathode fluroscent tubes are any good and you can isolate the inverter responsible for driving them them. Also the newer laptops use white LEDs which are useful.

Some (at least, IBM ThinkPad T22) laptops have the inverter board in the lid with the LCD so it's easy to get at. The video adaptor is built on the motherboard as Nigel mentioned. Gaming/graphics machines often have separate video boards but I wouldn't guess that's the case here.

Yes, sadly the only ready-to-use LCD sources are the PS-ONE LCD's and analog models with Video input

PSone LCD

I want one for xmas!

That's true, I've got some ThinkPad fluorescent tubes and the inverter lying around in one of my draws. The interesting thing is that they are hot cathode fluorescent tubes not cold cathode tubes. I wonder if they decided that battery life was more important than compactness so they went for hot cathodes because they're more efficient.
