How do I fix nexus 5 D820 display issue?

i broke my nexus 5 D820 upper glass accidentally for few days i was facing no problem working with my phone with a broken glass

but now my phone screen is not displaying anything nor touch is working but still my phone is working able to get calls and messaged but not able to access them LATER i realized it could be my display which has shattered possibly and i got it changed also but then also screen is not showing anything.

apart from it my phone's frame assembly is damaged from various places likewise my back panel

i have diagnosed my motherboard also it is working fine and the data is safe too

can i just swap my present phone's motherboard into another Nexus 5 D820 without loosing my data ?
