I should have been much more specific. Sometimes consumers will refer to rear projection systems like the method Sony employs as DLP. What Sony does for their rear projection systems is focuses a light source through three LCD filters (RGB), then reflect off the mirror on the back of the unit and onto the screen.
As evilchris mentioned Sony no longer manufactures LCD rear projection HDTVs. They employ Liquid crystal on silicon (LCoS) technology with all of there rear projection models. JVC also uses a version of this tech (JVC/D-ILA & Sony/SXRD). It is very similar to DLP (TI) but some say that the increased pixel count actually produces a better picture then DLP. You'd be amazed at how micro projection technology has evolved in the past 5 years. The latest models produce a fantastic picture with top notch IQ.
