How to fix my screen?

Basically, my Samsung A8’s screen is broken. It’s not the usual broken screen where the part you touch is cracked, it’s more internal. To provide some context, it had a strong case and glass protector, and was thrown hard on the ground. Cracks can be seen when looking at it, but they cannot be touched. I know that it works because it vibrates(from notifications/turning it on), and the light near the front camera turns on. No light comes from the display however.
