The next step is High Dynamic Range LCDs using strobed LED back lighting. We really need some of the major CE manufactureres to jump onboard and use this technology.

I read somewhere that you really could not see a difference with LED and the wide color gammut CCFL backlight the bravia is using. Something about the perception of the eye. I'll let you know if I find it. For my own experience I saw the LED on a Sony 46 inch 1080p and the Bravia 720p XBR with CCFL looked better. Same picture going in both sets. Now I don't if it was because it was smaller or the resolution was 720p. But it showed that the LED did nothing impressive. The backlight used on the XBR is not the same backlight as the Sony LCD sets from the S series. It is a high quality backlight.

The LED backlight system that is used on some of the SONY LCDs are not the same technology that HDR displays use. The SONY uses tricolor LED arrays to increase the color gamut. It does nothing to increase dynamic range.

The technology from Brightside uses a different LED system and increases the dynamic range up to 100,000:1 that's why it's called an HDR display.

Every where I read about that set it speaks of the Black level as the main feature with this backlight
http://www.dailytech.com/article.aspx?newsid=2860

In that article it calims to better than CRT, however, I seen the Sony XBR next to the top 3 CRT sets with the same signal going through it and the LCD XBR was killing those CRT sets.

So if they're talking about seeing an LCD that's better than a CRT, I seen it with the XBR and people I know said the same.

For the most part the CRT does has the best black level than LCD, but, the XBR is not a regular LCD, read the reviews, I seen it first hand.


"The picture quality is amazing; deep blacks, rich colors, and very bright… in fact, it’s too bright. This is actually a good thing, since over time backlights fade. I put it in reduced power saving mode, which cuts the backlight to an acceptable level. This Sony uses a new Wide Color Gamut-CCFL, which produces a whiter light for more accurate colors. One problem with many LCDs is poor black levels… not with this TV; blacks are very black. There were 0 dead pixels, which I would expect from a display of this caliber. The scaler is excellent… I can’t tell 1080i broadcasts from native 720p. DVDs look superb, and even SD broadcasts look good (on par with my old 27” CRT). "

Also the HDR lcd is said to be $49,000, which I'm sure will drop.

But with the XBR great black level, and it's wide color gamuit CCFL backlight, I don't see many people spending that kind of money.

I think we discussed this before

I did think the XBR was an amazing-looking LCD, but black-level off axis was not good--I could easily see the backlight bleeding through as a purplish glow. The solution is going to be microdisplay backlights that can actually be turned off when the pixels are supposed to be black (essentially what you have with a CRT). As far as price, I'll take a much larger plasma than the XBR for the same price.

I agree, if deep blacks are what you're looking for, just get a plasma. The plasmas have better response times and contrast ratios and higher colors up to billions. The Bravias are overated. My brother-in-law has one. Yes they're nice direct view LCDs but they have their own set of problems one of which is price, slow response times and ghosting. LCDs also degrade because of their organic nature unlike DLP which do not use organics.

"LCD's have an organic nature"

What exactly do you mean by that? As far as I know plasma is the technology that degrades over time, but neither are "organic". Are you sure you're not getting confused with "organic light emitting diodes"? Which I believe is a completely different technology.

ALL display technology degrade over time, but LCDs have two types of degredation..the first is the backlight brightness and the second is the organic compounds used for the liquid crystals. DLPs only lose brightness overtime they don't degrade because they don't use organic compounds. The bulbs can easily be changed too unlike the CCFL backlights of the Bravias.

The only way one should view a CRT RPTV is in a sitting position in front of the display. If you stand up, your losing more than 50% of the image brightness. Of course in a store, you can only see it standing up...

Trust me a CRT RPTV is difficult to beat in a room with controlled lighting (not too bright).

At this point, my feeling is that with all the slamming on LCDs about "black" has led to them to punching up the contrast level too far. Indeed, I get a black that is as black as it can be... BUT that leads to situations where I should get some image, but all there is is solid black (known as blocked up shadows in "picture parlance"). AND it is VERY dependant on the source. Interestingly enough, PQ settings seems to have actually much less effect (meaning a change in settings doesn't have as much effect on the image) on those stunning HD images from video sources like DiscHD.

Those articles made sense, but it seemed to a pro DLP vs LCD rp promotion. None the less, reading the fine detail this is what it came down to in the 2nd link you posted.

"Manufacturers recognize that the organic compounds in LCD panels and polarizers are susceptible to high heat and light energy stress, and will eventually break down if deployed in high stress environments—in particular 24x7 operation with higher than normal ambient temperatures"

But...For the most part you read this everywhere

"LCD manufacturers claim that their displays last, on average, 60,000 to 80,000 hours. In point of fact, an LCD TV will last as long as its backlight does -- and those bulbs can actually be replaced. Since this is nothing more than light passing through a prismatic substrate, there is essentially nothing to wear out on an LCD television."

i think people got away from the original post. the new lcds in the link i posted dont have the downfalls that the lcds out now have. in fact if what is being reported is true then lcds will be the way to go very soon. im not an lcd fan at all but if this comes true i will quickly jump on the bandwagon.

There is so many people in the same boat as you. You get a Tv, yet there is something else that is coming out..its addicting! The price's on these items now vs. a few years ago doesnt help either! I'm eager for the SED models, and I own the Sammy' LCD from last year. Now, they have that all white model out that looks so inviting!

Drooooooling.....
