You can't directly connect the display connector to the bottom of the logic board without removing the screen, but you might successfully connect it by screwing the logic board in place. Be sure to test your iPhone before you seal it up.
Make sure the logic board rests in place against its screw posts. The posts will properly align the board to the display connector underneath it.
