Liveview Phase Difference autofocus

On the Canada Ricoh site, perusing the specs for the K-3, it says under LiveView:

Autofocus: Contrast + Face Detection, Contrast Detection, Phase Difference

Pentax Canada | K-3

What does phase difference refer to?

It uses same AF as non-liveview (PDAF) -- it will blank out screen while it focuses. K-5, etc have the same feature...
