Will a new LCD Screen be enough to fix my phone?

I have an iPhone 6s. I dropped it the other night and it was still playing music just the screen went black. I turned off the phone and ordered a new Screen replacement.

Now because the phone was still working after the screen went black, does that mean when i change the screen will everything work as it did before?

It should as long as the only damage was to the LCD and not another internal component.
