Shattered iPhone 4s, display doesn't work but sound does?

I dropped my phone, the whole front screen is shattered but I still get calls, my phone still rings and makes sound when I take screenshots but the display is completely black. When I press the home button the screen barely lights up but is still black. If I replace the front screen will it work and display again?

It's obvious that your screen assembly has been smashed, and you can onlyreplace this handset to make it work again. Your iPhone 4s consists of a screen and digitizer that are integrated together.

It will work after.
