3D TV?

I saw an interesting letter to the editor of an audio / visual type magazine this month. The guy pointed out that 3D TV requires special glasses having electronics inside. So he asked why not just build the display itself into the glasses and skip the TV altogether. Sounds like a good question to me!

It would be awesome to have the image in glasses, but it would be more expensive, because each person would need one, and you are taken out of reality from being able to communicate with others about the movie you're watching.

Seizures....to close to the image, but when everything finally does go 'star wars' I'll be happy.

Ethan, probably because incorporating the glasses technology into the display would give you a very narrow viewing position. Probably only one person at a time could see it and even then, they would have to sit in one spot and not move their head.

3D is a sales gimmick, anyway. There simply isn't enough content and no compelling reason to put a lot of content into 3D. Would 3D enhance a newscast? I don't think 3D would be compelling unless it is a movie specifically designed for 3D.

Also, the glasses are a pain. I wear glasses already and, after a few years of use, gave up on contacts. They're a nuisance. I've been to a handful of 3D movies recently and I did not like wearing glasses over glasses. And there's no way in hell I'd pay for prescription 3D glasses.

The gimmick will be over in a year or so. My guess is that there will be deep discounts on 3D TV sets after Boxing Day.

What I think will take off is 4K. A genuine improvement and there are rumors that Apple is going to get behind it. Makes sense since I think the Retina Display will turn up in all Apple products soon enough and other manufacturers will increase resolution, too.

Hey, I love my Toshiba CRT more than any TV I've ever demo'd. Thank you Sears, FutureStop and a number of local stores.

However I can only enjoy CRTs at around 3 to 5 meters. If I use a CRT computer monitor than I get eye pain. Eh.

It's currently in the 'early adoption' phase. I'd leave the people with more money than sense to it and come back in a couple of years and see how things stand. I don't think it'll go away, but the technology certainly needs to improve a bit, and more content to be produced in real 3D rather than crappy 2D-3D conversions before everyone takes to it.

I'd rather them focus on moving to higher framerates.  1080p is fine, we DO NOT need higher than that.  If they went to say 1080p72 it would be 3x the amount of detail as a 1080p24 image, and would be clearer and more realistic motion.  Screw 3D.  I know I'm watching a movie and that's the point of it.  I don't need 3D to be simulated.  If they want things to be that realistic they should make a way to pump a movie into your brain as if you were living IN IT, like the Matrix, but just as a viewing party.  They can record video at millions of frames per second now without needing a nuclear blast of light to illuminate the subject, so 72 FPS should be easily doable.  Even 720p72 would be far superior of an image to 1080p24.  720p60 is already known to be a better picture than 1080p30.

3D video games is something I want much much more than television. You can eliminate glasses by having two screens at an angle, and a parallax filter. Of course this limits angels and view distances much more.

Its horrible, been out for a decade.  PQ is horrendous.  If you think IEM technology is behind speakers you don't want to know what TV glasses look like at this stage of development.  Plus eyestrain?  No thanks.

 

Plus glasses free 3D TV is about 2-4 years away anyhow.  The panels exist now.

 

Wrong forum btw.

 

@ Uncle Erik - Yes most 3D content is crap and so is the tech.  Even Avatar was highly flawed and I saw it in Real3D and IMAX3D.  If you get to CES this year, go demo the Sony OLED 3D screen.  Holy mother of god.  The closest thing to watching a real polar bear swimming next to the real thing.  I'm not prepared to pronounce it dead yet.  4k?  Well, despite Apple I don't know how they or anyone will get all the stations, satellite providers and screen makers to convert to all new gear for 4k just after doing the 720p/1080i swap.  Is Apple going to provide everyone free studio and film cameras and launch the satellites?  Is Steve jobs mortal??

Obviously, Steve Jobs is not mortal.

He'll be the first human uploaded into the Singularity.

Haha!   Let's hope he knows how to hold it right.
