My screen is glitched after I accidentally laid down on it.

after laying down in bed, the screen glitches. I have warranty, so i can get it replaced, but can i get my data and information off of it? I can still operate on the tablet, everything just glitching which makes it harder to use. any help on removing the data?https://twitter.com/luna_deerwood <-- A temporary twitter account with an image lol
