You have to check the specs for your display's EL backlighting. Check the manufacturer (Matrix Orbital, Densitron, Varitronix, etc) and look for the model's datasheet... When I bought mine from Digikey, it listed the part number for the compatible inverter, which I purchased along. It is very small (about the size of a pair of dices) transformer-like thing. I think inverters used on computer modding are for fluorescent tubes, and they would probably fry your lcd's backlighting!
