Invisibility, darkness, and most kinds of concealment are irrelevant, though a creature with blindsight must have line of effect to an object or another creature to discern that object or creature.
It bypasses concealment unless the specific form of concealment says otherwise. Displacement is a form of concealment.

The creature is sensitive to vibrations in the ground and can automatically pinpoint the location of anything that is in contact with the ground.
Tremorsense only pinpoints the square of the creature, so displacement is fully effective.
