Cross-referencing part numbers for Gateway laptop screen

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

I used to have a URL for cross-referencing part numbers for a Gateway

I have a W340UI which seems to take a LP141WX3-TLN1 Made by  LG-
Philips or a LTN141W3
Made by Samsung

Does anyone know how to cross-reference this 14.1 1280x800 WXGA Glossy
screen to get the part numbers (if there are any) for  Chi-Mei,
Chunghwa, Hanstar, Sharp,  Quanta,  Au Optronics etc etc etc please?
