Samsung Tablet - Gray and wavy screen

Trying to fix my tablet since I accidently stepped on it and was wondering what I need to replace. Theres no cracks on the surface but underneath the screen.

It sounds like you only damaged the screen, it would be pretty obvious if the digitizer was also broken. Does it still work? Can you still use it at all? What model is it?

Its a Samsung Galaxy Tablet 3. Doesnt work at all when you turn it on
