Ran across this and thought it might be of interest.

DALLAS, April 11 /PRNewswire/ -- Texas Instruments (NYSE: TXN) (TI) today
announced that its 1920 x 1080 high-definition (HD) resolution DLP TV
technology has been fully qualified and is in production shipment to
customers. DLP TVs are expected to be the first volume 1080p TVs available on
the U.S. market, with affordable 1080p DLP TVs scheduled to be at retail as
early as July.
Manufacturers who have announced 1080p DLP TVs include LG, Mitsubishi,
Samsung, and Toshiba. Mitsubishi will publicly introduce for the first time
today 5 new models featuring 1080p DLP technology, ranging in screen size from
52" to 73", at their line show in Orlando, Florida. 1080p DLP TVs will
complement the 720p high-definition DLP TV offerings available on the market,
which total more than 75 models from more than 20 customers worldwide.
The 1080p DLP chip offers a variety of features to customers that allow
them to differentiate their TVs:
* SharpPicture(TM): Processing enhancement that works in conjunction
with SmoothPicture(TM) technology to simultaneously provide sharp, yet
smooth and seamless images.
* DynamicColor(TM): Enhances colors and contrast without impacting skin
tones, allowing for more vibrant and lifelike color reproduction.
* DynamicBlack(TM): System level solution which provides dramatic
increases in system contrast ratio and grayscale fidelity by as much
as 4x, bringing greater detail to dark scenes and images and allowing
customers to achieve contrast ratios well above 5000:1.
* DarkChip3(TM): Feature that includes architectural changes to the DLP
chip resulting in a 20 - 40% improvement in contrast over
DarkChip2(TM).

With the highly anticipated industry move to 1920 x 1080 resolution
digital capture, broadcast and playback, 1080p DLP TVs are designed to display
incredible high-definition pictures that match the full content resolution.
According to In-Stat, there are currently 4 million HDTV households in the US,
up from 1.6 million in March 2004. Many HD cable and network programming
offerings have already moved to 1080 resolution, and the highly anticipated
HD-DVD and Blu-ray Disc technologies for high-definition video playback are
expected to make their debut later this year.
"This is an exciting time for HDTV, as we are seeing large quantities of
HD content and consumer products to support the content," said Dale Zimmerman,
Business Manager, DLP(TM) TV Products at Texas Instruments. "We are pleased
to provide our customers with a 1080p resolution chip so they can continue to
lead the TV market with innovative DLP TVs."
The inherent advantages of DLP technology include no burn-in or fade, deep
rich colors, and incredible, industry-leading contrast ratios. The speed
advantage of DLP technology allows for a 1-chip architecture that provides
razor-sharp images that will not misconverge over time, and excellent
reproduction of fast video such as sports and live action with no motion lag.

About Texas Instruments DLP Products
Texas Instruments DLP display technology offers clarity down to the most
minute detail, delivering pictures rich with color and brightness to large-

What TI has done is create a chip that has 1080 X 920 mirrors. This allows
the entire vertical info presentation (ie 1080 pixels), but to get the full
horizontal (ie 1920 pixels), a mirror is used to shift the light path either
to the left or right. This is very different than classic interlace and how
it will appear to the eye is yet to be determined by the masses. Remember
that the rainbow effect that the single chip DLP sets exhibit is not seen by
everyone, so there may be display artifacts that are not being discussed.

This is the same thing they are doing with the current HD3 chip (which
is doing 720p with a 640x720 mirror array). All the Samsung HL-Pxx63
models use this chip. If you look really close you will see the pixels
are diamond shaped instead of square so that is any easy way to tell
what you are looking at if you can get right up to the screen.

Ok, that was news for me. How long has DLP been using this technique?
From the beginning?

Thanks

No, it started about a year ago, with the HL-Pxx63 Samsung's. Anything
that says it is using the HD3 chip is using that technique.

Hugh,

The thread below may help you clarify visually how wobulation is used to get a 1080p image from a
(cheap) chip with half the pixels (xHD3).

Look at the computer graphics comparison between true 1080p, xHD3, and downscaled 720p (down the
middle of the first page of the thread).

On top of that weakness the Sammy xHD3 sets are not able to accept 1080p externally, not on their
2005/6 models.

Does this chip work very well with 1080p now?

The acceptance of 1080p was a design issue for any display and there were many true 1080p first generation that would not accept 1080p; some of that spilled over into 2nd gen products too.

The only DLP RP available now is from Mitsubishi and still uses the technique described here to create 1920X1080 from a 960X1080 device.

The benefit is pixels are difficult to see yet that also diminishes ultimate resolution and clarity. Another factor for 3D is this technology requires checkerboard encoding for 3D and will not accept full frame left/right eye. While that may seem detrimental a Mits DLP was recently reviewed for 3D and the result was no visible difference by the reviewer; the optical illusion works!

At this time you cannot beat this product for pricing based on screen size. Based on that this product makes sense for many people, even videophiles. The smallest size now is 60" going up to 82".

Bear in mind this thread covers only DLP RP. All DLP front projection has used true 720p or 1080p DMD devices.

BTW, there was a lot of commentary at the beginning of this thread about the wobulation mirror concerning size and noise. The mirror is at the final of the light output prior to the final lens so it is small as I suggested way back when. If I were to make you aware of the noise it creates then you would also be aware and able to identify it yet it is certainly not pronounced mixing right in with the rest of the noises coming from the product.

I received my Mits WD-82738 just before Christmas from Amazon; I could NOT be happier! The 82" screen is phenomenal....clear, precise, bright colors all the time. I was also blown away by the 3D; have 2 pair of Viewsonic glasses (am waiting on the Optomas) and DirecTV 3D channels; really stunning 3D! I'm looking forward to the BCS championship game to be broadcast on ESPN 3D! I had a JVC 70" and just could not go down in screen size, so when I saw this Mits at a great price, I had to have it! Hopefully, this will last a long time, until LCD sizes get bigger and cheaper!

I may have missed answering an important point...

Yes, nearly all displays today accept 1080p, especially if they are 1080p to begin with. This statement does not reflect any video processing that may be applied before the image makes it to the display which may negate some of the advantages of 1080p and 1080p at 24 frames. Videophiles should check reviews for such anomalies before purchasing.
