I drop my iphone and the screen cracked ect but?

So today I broke my iphone, it drop. The screen cracked badly and the lcd screen is black but some type of light shows in the small little cracks of the screen. So I was thinking can I just replace the screen and the lcd screen and my phone will work again? My phone still charge and vibrates and such.

If I were you I would go to a repairshop or the apple store that happened to my friend and he ruined it so you should leave it to the pros
