Please could you say the type of LCD screen? Or present detailed photo of rear side?

Yes, this is a guide for replacing the LCD. I'd like to know what LCD to order. Thanks.

Thank you for providing this tutorial. My dog, not making this up, knocked my nest off the wall. Where can I purchase the replacement green itself and the plastic opening tools you used throughout the repair? This will be my first time on something like this, but with your guide I should have a decent shot at not screwing it up.
