All 1080p DLP RPTV sets in the market are expected to be wobulated for 2007. It makes no difference which company builds them.
Since the first 1080p RPTV sets arrived in 2005 they have all been capable of projecting 1920x1080 uniquely controlled pixels on the screen. The term "true 1080p" is a marketing term.
The resolution on the screen is not "mimicked". It's alternated at a very high rate of spead. Much faster than film where we're shown a still picture every 24th of a second and we think it's a "moving picture show" or "the movies".
These two links deal with wobulation more intelligently than I can.Wobulation is, from a user perspective, a NON-ISSUE.It's the speed.
The wobulated DMD 1080p chips have 960x1080 = 1,036,800 mirrors. Each mirror is responsible for controlling the content of two adjacent
pixels on the screen. Each of those two pixels
is supplied with it's own unique information
depending on the image being displayed.
The mirrors on the DMD chip do their work so fast that your brain and vision do not detect any gaps in the presence of pixels on the screen. What is projected is true 1080p even though the 1,036,800 mirrors "wobble" between pixel A and pixel B.
Think very very fast.
TI has a DMD chip with 1920x1080 mirrors. So far it has only been used in high end front projectors. Optoma and others have introduced mid range (~$7k) front projectors using that chip. At this point a 1920x1080 mirror chip may be too expensive for the RPTV market.
All the wobulated 1080p RPTV sets are "native" 1080p because you perceive
all 2,073,600 unique pixels
as being projected onto the screen at the same moment. The fact that they arrive at slightly different times is not perceptible.
