Cracked Screen, how to open?

I cracked my screen yesterday and it has 2 chips on the front plate and then cracks that go to the end of the screen.

So i want to replace but dont know if i need both ports of the screen (face plate or actual screen) how do i open it?

Will opening it void my warranty and if so, is there anyway to cover it up?

Once you open it up, warranty is voided no way to cover up.

Why you need to open it ? Didn't you purchased insurance ? If yes then call them and have it replaced for you.
