Will there be ANY Direct-view CRTs at CES?

Just wondered. Are any of the Chinese companies still making Direct-view CRTs?

The only companies planning to announce new CRT tube models in CES are LG, Samsung, and Toshiba. That's all. Sony may release two new widescreen models quietly without announcing the models.

Sony will release TWO widescreen models.

Are these sub quality models contracted out to another company? 30", 34"?
Superfine Pitch?
Guess we all have to wait.

Who knows. What I'd like to see is a CRT that is truly 1920 X 1080 but I know that won't happen.
post #6 of 54
I'd like to see native 1080p, but I doubt it highly.

I'd like to see 720p 38-inch widescreen super fine pitch.

Sony will create a slim version of 36" 16:9 Super Fine Pitch 640x480p / 1280x720p/ 1920x1080i native

Ha Ha , yea right King Reyes, although that is possible and would give much needed respect to the tv tech that made them famous, I'd buy for sure.
i think it's more likely we will see slightly upddated versions of the 970, and a 30"
What I would like is a progressive version of the 960, which could be called 1080P and should'nt be that hard to do, or a 960 version with true 480i-480p-720p-960i-960P (dvd doubling mode less artifacts smoother image than 720P1080iP upconversion) and 1080i-1080P (1440x1080=1.5 million+ pixels) and user selectable or set to auto this should be easy to do , like on crt pc monitors.
Unfortunately almost all of Sony tube plants are closed, LCD's are cheap to make and have high profit margin and lower shipping cost and take up less retail space, also such sets would look better than even there best LCD,s as I believe the 960 did and it was promptly discontinued.

I'd like to see a Sony CRT that doesn't weight 900000000000 lbs.

That would still SED's thunder in everything but size and price, and wouldnt cut into the lcd price ranges, hmmm.

A slimmed down CRT wouldnt be able to do edge of screen convergence very well (something they dont do perfectly now) . Samsung's model case in point

Careful what you widh for...you might get something made by Orion or Funai.

That's highly unlikely.

I would like to see a nice, quality built shadow mask based HD CRT, they typically have a bit better blacks (naturally because the mask is more light restrictive around each pixel) and weigh, on average, 20% lighter than aperture grille based CRT's

SED isn't coming to CES................. Toshiba and Canon failed.

Uh, no. They got sued. Massive difference. Though, as one site put it, a technological failure would be a speed bump compared to the trouble a lawsuit can cause.

While we may all wish for a CRT with such great features as 1080p, I'm afraid the days are numbered. ROHS (Reduction Of Hazardous Substances) legislation is starting to work it's way in and will kill CRTs due to the lead content of the glass. The US is slower to adopt ROHS but it will happen. In Europe the legislation is far more advanced and you won't find any CRT sets on the Sony UK web site for example.

Enjoy your CRT while you can.

ROHS is being adopted in places like CA - the redesign of a PC board inside of a CRT TV would be expensive enough to kill the TV redesign. Things are so global that the US will get ROHS equipment by default.

This is just what Samsung was putting out about 4 years ago and earlier. Their sets included very tight dot pitch as well. I'm still loving my TXN series set, what an incredible picture. It's actually an ED monitor, native at 480p and I will keep it as long as it works. Then I'll repair it to the component level until there's no more available.

Unfortunately, no company has announced any new CRT models. Does that mean they are not making them anymore?

I don't understand your claim about shadow masks being "light restrictive" and giving better blacks. Do you mean with respect to back-scattered light? I don't see that as a problem if the aperture grille wires and inside of the tube are painted matte black. Nor do I see how a shadow mask alleviates this problem since the shadow mask presents a much larger surface area for the phosphorescent light to reflect off of.

Shadow masks in my understanding are inferior to aperture grill in every way, except for allowing the tube to be vertically curved and thus the front glass to be thinnger and lighter. But I wouldn't call a curved screen an advantage.

Oh no, the rumour was Sony would have 2 new or renamed CRT's.
I was hoping for a Super fine pitch model at $999-$1299, Sony would clean up in the one area they are superior to everyone else.
CRT Direct-View Tubes.
Oh Well It is a sad day indeed.
I hope my current XBR960 last along as my older one 17= years
My friend the superior PQ quality crt, is just about gone for good,, it was/is fun.

I think you are mistaken.
post #25 of 54
Shadow mask tubes, typically, have a tighter pitch than aperture grill tubes.
Much like a super fine pitch AG tube is darker than a regular AG tube.
Also, the shadow mask prevents some electrons from ever striking the phosphors and that further reduces light output. You can increase the drive, but at the risk of overheating the mask.

About the better blacks part, can you provide a link, I though Trinitron Aparture grill set up had the best blacks, but if I am wrong can you point me to where you got your info.

TX-T3093WH: 30-inch, $699

I think I understand why people think this.

The light restrictiveness of a shadow mask has no bearing on the black level of a CRT when it's sitting in your living room since the shadow mask is behind the phosphor coating. However, in manufacturing, the higher light-restrictiveness of a shadow mask results in larger black gaps between the phosphor deposits than with aperture grille. This is because the phosphors are etched/deposited by shining light through the shadow mask/aperture grille.

The black level of a direct-view CRT is limited by the phosphor coating reflecting ambient light back to the viewer (ignoring glass glare), so the more black gaps between the phosphors, the deeper the black. But more gaps also means lower phosphor density, and hence a less bright CRT.

Thanks, you put that very well, that is sort of what I meant by saying, in a very crude way, more light restrictive. It just seemed to me that every shadow mask CRT I have ever seen has generally had what appeared to be darker blacks when there was a lot bright and dark material on screen.

Perhaps the natural gamma of Sony CRT's is more logarithmic as well, I always find that when I am watching my Sony CRT's I am constantly adjusting the brightness and contrast to get the colors to look as dark and "rich" as my shadow mask CRT's. I mean the Sony does look good in its own way, it is very bright (actually too bright) and does have excellent blacks but for some reason I find that I am just a little bit more content with shadow mask based CRT's.
