Upgrade screen Lenovo Legion Y720

Good evening! I have a screen N156HCE-EAA Rev.C1. and I plan to replace it with B156HAN04.5.
Questions:
1. What do the last numbers mean in signal pin configuration: EDP-30P2L-020A с EDP-30P2L-030A, EDP-30P1L-030D, EDP-30P2L-020W или EDP-30P2L-020Q? I guess 30P = 30 Pin, and 1L/2L = 1 or 2 lanes, (so those 30P1L compatible with 30P2L) but what about the rest?
2. Who generally updated the screen on this laptop, can you share your experience what screen did you install
3. What is signal interface model and what is the difference between them?
I will be glad to help, thanks!
