My dream is to own a HMD with 2 different screen for each eye with high FOV. This is a perfect setup for 3D.

You mean like this?

I can't imagine enjoying that to watch a 2-hour movie let alone playing KZ3/R3 online with it. It's too heavy. The 1280x1024 dual-input version costs US$10,500 and it can't even be hooked up to a dual-DVI graphic card. You can also find xSight on that site that supports input for 1080p but it doesn't indicate native resolution. For the pricing info, you must call to find out which means it costs more than US$10,500.

I could build a circular polarized passive system using 2 Optoma 3D-XLs, 2 Panasonic AE4000U, a 120" DIY silver screen and circular lenses for under US$8,000. You can still use it to connect to a PC to play 3D games at 1080p.

Initially, this big lenticular display will target businesses, who'll be among the few to be able to afford the ¥1.7 million ($20,820) asking price. Other specs include a 2,000:1 contrast ratio, 8ms response time, 700 nits of brightness, and a 60Hz refresh rate.
Auto-stereoscopic screens that are over 20" uses lenticular laminate. While it does give you depth, you can't really see fine detail. Case in point - the auto-stereo lenticular display at the Ground Floor of Low Yat. I've also seen another larger screen display that had the same problem.

I'd rather the FPR tech with passive glasses than this. At least with passive glasses, they can increase the 3D resolution to 1920x2160.

Incorrect use of a term. Lenticular screen achieves AUTOSTEREOSCOPIC 3D. Passive 3D still uses glasses that have either linear or circular polarized lenses.

1920x1080 not enough for you?

Wiki entry for Lenticular printing. Read it first to understand the concept.

For LCD displays using lenticular laminate, the laminate is arranged vertically in order for each eye to receive separate video information. Unlike Cinema 3D which cuts vertical resolution by half (1920 x 540), lenticular 3D cuts horizontal resolution by half. In effect, each eye will get 960 x 1080 video resolution per eye. What's important to note is that humans are more able to know there is a resolution loss when the loss is horizontal and not vertical.

LG's LW5700 series is here. Just saw a 47" version. The price is RM6,700.

It works as advertised. You must sit at eye level and about six feet away to get the full 3D effect. Too close and you'll see the interlaced effect. Too off axis vertically and you'll see ghosting.

At eye level and six feet away, there is no ghosting which is an impressive feat. There is no flickering because both L+R video is shown at once. And the image is brighter than active 3D.

The only drawback - the horizontal resolution loss is a given - is the price. At RM6,700 that's a lot to ask for a 47"; in the US, you can get a 55" for US$2,000 and we're closer than Americans from Korea or China. The list price for the 55" is RM13,000, double the price of the 47". If you add another RM7,000 you can get a 1080p 3D passive projection system using two PT AE4000-Us and 3D-XLs.

The TV comes with 4 pairs of circular polarized glasses. If you buy one from LG, it'll cost RM30-40. If you buy from Ebay, it'll cost you RM75 for 10 pairs of RealD 3D glasses.

If by that you mean when the children break the glasses, you won't cry to pieces, then yes.

Hopefully circular passive 3DTV would sell so well that GSC and TGV would actually start using RealD 3D instead of Dolby 3D.

I read that. Nonsense, really. Kids do other things beside watching TV, like play and read and going to school. Even just going from the living room to their bedroom requires spatial analysis with their bare eyes.

What 3D does is it enables the brain to adjust to a different kind of space. It synthesizes new space so that more spatial analysis can be done. The warning on the article applies to all 3D, and not just active shutter glasses.

I know this is a stupid question to ask, but just want to prove some theory.

Nowadays there is a lots of 3D LED/LCD around, you need 3D glasses to watch 3D movie, that if, in situation where the movie is in 3D, (player.....i don't know, but i guess most of the Blue Ray players can play 3D movie). What if watching normal TV program, like TV3, NTV7.... Those 3D LED/LCD will goes back to normal mode right ? Or...for example, watching Astro.
*

The active LCD glasses won't get activated because the TV recognizes the signal is regular video. At which point, you should turn off the glasses and take it off.

New passive 3D projector prototype announced.

QUOTE
VALENCIA, Calif., June 15, 2011 /PRNewswire/ -- Wavien, Inc. will be demonstrating the latest advances in LED light engine technology with a prototype 3D Projector using its proprietary LED Recycling Technology (RLT™).

Wavien's low cost 3D projector combines the left and right polarized images from two TFT-LCD panels using a reflective polarizer, and projects the combined images onto a polarization-preserving screen through a single projection lens. The 3D image can then be viewed using low-cost polarizing eyeglasses. This system allows use of a "home-made" polarization-preserving screen, produced with off-the-shelf metallic spray paint, which further reduces the total cost of ownership. Wavien is working with manufacturers in Taiwan for this 3D projector. A 2D version of this low cost LED projector is also available.

A production ready 2D sample and a 3D engineering prototype will be shown at the Wavien booth, #5283, at the InfoComm in Orlando, Florida, from June 15th to 17th. Performance, pricing, and delivery details for these new projectors are now available from Wavien.

"Our goal is to provide a low-cost, maintenance-free 3D projection system for home and classroom uses. Wavien's RLT technology utilizes a low-cost, street-lamp type of LED, and costs are reduced even further by using large area TFT-LCD panels to simply the light engine architecture. The two-polarization system permits the use of low-cost, passive polarization eyeglasses, instead of expensive LCD shutter glasses. A further innovation is to project the images onto a simple metallic spray painted screen, which is polarization preserving and has high gain," stated Dr. Kenneth Li, President and CEO of Wavien, Inc., who is also the inventor of the recycling technology. Dr. Li added: "This unique combination of low-cost components makes 3D viewing at home and in classrooms affordable, which is one of the major factors in the widespread adoption of 3D."

Ron Meritt is president of Olens Technology, based in Pismo Beach, CA.

"Olens Technology is excited to work with Wavien, a global leader in projection technology with the RLT technology," stated Mr. Meritt, who was featured in many media outlets including the cover story of Forbes Magazine. "We are very optimistic that Olens Technology will be able to introduce this 3D projector as a leading product into the market using Wavien's technology," added Mr. Meritt.


It may not give accurate color reproduction but at least a new projector company is bucking the trend of 3D projectors by going passive.

Question:
Is there any sample 3D movie clips that i can download to watch using this 3D TV?
I tried Anaglyph 3D, but it is for red-cyan glasses, not for Polarising 3D glasses (correct if I'm wrong).

You can Google for any "half SBS" content and download that. If it's a Samsung TV with a USB port, you can put the content on a flash drive and play it from there. Just remember to tell the TV to show SBS content as 3D (SBS stands for Side By Side).

If you have a PS3 and a US PSN account, you can download several game videos that are in frame-packed 1080p 3D.

Thanks for the info Fuad.
Oh, if it is a SBS format, so it is almost the same like a stereograph photos or movie then, which you have to look using parallel or cross-eyed technique.
*

It is kinda like that, except that stereograph photos have full photos side by side.

SBS videos (rather half-SBS) have two SQUEEZED video images side by side to fit the 1920x1080 frame; each image is 960x1080. The TV then STRETCH each image and show them as Left and Right image on the screen. There are Full SBS videos but you can only run them using HTPCs and 3D monitors.

Considering that Harvey Norman and Best Denki sell that model for RM6,600 and you get it for RM5,000, that is reasonable. Five glasses and some free gift? I'm sure others would like to know where you bought this.

Remember that vertical placement is key. Don't put it too low or too high or you'll see ghosting.

rm6600 ?! they told me normal price is only rm5399.
i did the test there.. if eye level higher than TV will see ghosting, but if lower abit still ok.
bought from Perfect Livin fair at pisa penang. free gift is 5 glasses,1 high quality stainless steel pan and one non stick pan.

Well you lucked out. And it goes to show that electrical shops are getting huge profit from TV sales markups. 10% of RM5,000 is RM500. If that's what the store gets, the salesman at most gets half of that. By the way, I'm just guessing on the percentage.

Although I would prefer that the retail price of the 55" is around RM7,000 (which means the 47" is around RM4,000) I'm glad you got yours for RM5,000.

LG has a Cinema 3D range that doesn't have SmartTV stuff. Is that the range you're talking about? Supposedly it's coming sometime this week.

LG passive cinema 3dtv is surprisingly good but vertical viewing angle is a bit restricted....

Yes, vertical angle is a bit restricted but most people won't grow 6" taller in 10 seconds if they're already standing up. On the other hand, active 3D doesn't have as wider horizontal viewing angle as passive 3D TVs do. It's almost 140 degrees for passive which means for a big party, people can sit all over the place. You also don't have to worry about syncing your glasses when you're neither near nor far because it never needs to be in sync.

Just to be clear, if your view is vertically higher than the TV, you'd see ghosting. But that disappears when you're back in position or you tilt the TV to your direction.

RED sorta announced their upcoming 4K 3D projector on their forum. It uses a laser as its light source. 4K is the resolution, not the price. No word on the imager but it is definitely not DLP. Available for theatrical and home use. "SOON" is the delivery date.

RED is the maker of RED digital camera, like the RED Epic, which was used to shoot next year's Spiderman and PJ's The Hobbit films.

Added on November 17, 2011, 11:22 pmKL's 3D Cinema Screen update. Some people may have known this already and others may not.

TGV KLCC have installed a silver screen in Hall 2. This means that it is now able to play 3D films using RealD 3D. If you don't like the glasses of Dolby 3D and the active shutter glasses of Maxx, you should give RealD 3D a try. If you have the LG Cinema 3D series, you can use those glasses to watch in 3D. I don't know if you can insist that you shouldn't pay extra for the glasses you don't need. If you can, do! If you can't, then at least you get to keep the RealD glasses which you can now use at home. If they give you any trouble about either one, write to the newspapers!

TGV may have installed silver screens on their other cineplexes at all as apparently TGV is going through a renovation phase. TGV is now installing Digital Imax at Sunway Pyramid. I doubt it would be as good as Maxx but at least TGV can start showing Imax films there. It won't be the same though as the screen on Digital Imax is only slightly bigger than regular screens.

For US$10,000 The REDRay projector also
- Includes an internal REDray Player
- Also accepts HDMI or HD-SDI input


What's a REDray player? It's essentially a player that can read REDCode formats directly from the RED Epic/Scarlet/One SSDs. The REDRay can also display FOUR 1080p content simultaneously. Here's a gist of the specs.

user posted image

The REDray projector's main user will be content creators shooting at 4K and using the PJ to grade their content. But as you can see, you can also hook it up to your PS3/Orbis for some 1080p 3D gaming.

Is those major Studios will support the REDray format?  hmm.gif

RED is working on getting DCI approval for RedRay projector and player. Encoding can be done already via software/hardware solutions. Distribution can be via SSD delivery or direct download to server.

Here are the pix of the projector Engadget took at the RED booth. Click to see.

What DCI approval means that the REDRay projector is designed to replace not only current LCD/DLP/D-ILA home theater projectors, it is also designed to replace current DLP cinema projectors that uses Xenon lights.

The projector design is a modular one. The home/grading studio version can go up to 15'/180" screen but if you want a bigger screen, you send the projector back to them and ask for a laser and imager upgrade. Supposedly for larger venues, the projector will cost up to US$40,000. Current Christie Digital DLP 2K projectors cost US$120,000. The key thing to remember is this : just like their cameras, the REDRay projector is also upgradeable. You don't need to buy a new projector if 6K is coming; just upgrade the laser and imager.

RED also just announced the Dragon sensor which can capture images at 6K. Very soon, maybe under 5 years, RED cameras can capture images at the same resolution as 70mm Imax films, which is currently at 10K. By that time, Imax may actually be a client for RED.
