Toshiba Announces Lenticular Displays: No Glasses Needed. 3D Regza GL1

Monday, October 4th, 2010

Toshiba announced a lenticular display, same technology as the Phillips WowVX.

Based on the form factor, with an really ugly base and a mere 20 inch screen, I am thinking this must be for commercial / advertising applications, not home use.

The press releases mentions 9 images (the idea is that you’re eye will pick up only 2 of them. If there are images A, B, C, D, E, F, G, H, and I, and you are standing towards the left, your left eye will get say C and the right eye D). How the TV will generate 9 images is a little confusing to me. Either they’ll require that the content is produced with 9 cameras (unlikely, but possible for advertising applications), or they’ll use 2D->3D conversion technology to take a 2-image 3D image all the way to a 9-image 3D image.

The resolution is crappy – a mere 1280×720. But it lists 8,294,400 pixels. 1280 times 720 equals 921,600. Times 9 is 8,294,400.  So clearly, TV has a lot of pixes. Also, they’ll be squished vertically to work with the lenticular sheet.

Toshiba Unveils World First[1] 3D LCD TVs without Dedicated Glasses
-Toshiba’s new Glasses-less 3D REGZA GL1 Series to be available
from end of December -
4 Oct, 2010

Tokyo—Toshiba Corporation (TOKYO: 6502) today unveiled the world’s first[1] LCD TVs that offer comprehensive 3D[2] capabilities without any need for dedicated glasses. The new “Glasses-less 3D REGZA GL1″ series offers two models with screen sizes specifically designed for personal use: the 20-inch 20GL1 and the 12-inch 12GL1. Both TVs will be available in Japan from the end of December.

The new 3D TVs with no need for glasses employ an integral imaging system[3] and a perpendicular lenticular sheet[4] to display smooth, natural images, and Toshiba’s image processing technology to create nine parallax images[5] from the original content and create to 3D images. The result is precise rendering of high quality 3D images whatever the viewing angle within the viewing zone[2].

The 20GL1 integrates a high definition LED backlit LCD panel specially designed for 3D capability without any need for glasses that offers approximately four times the pixels of a standard Full HD panel. It also integrates the Cell REGZA Engine designed for 3D capability without glasses and based on the Cell Broadband Engine™[6] to deliver superior multimedia processing. The result of this combination is stunningly sharp, dynamic 3D images.

Toshiba will respond to various needs from the users for LCD TV with 3D capability. This will include larger screen models that use dedicated glasses and personal use LCD TVs without glasses, all offering dynamic, stunning image depth and high image quality. Toshiba will continue to draw on synergies of its semiconductor and image processing technologies to advance REGZA series as the cutting-edge of TV technology, and to create and deliver new value to the market by continuing to expand its line-up, and by anticipating and responding to user needs.

Background to Development

Toshiba introduced the REGZA series as state-of-the-art TVs that make full use of synergies between its semiconductor and image processing technologies. Originally a 2D platform, REGZA TVs now deliver 3D images with superb quality to achieve an unsurpassed 3D experience.

Current 3D TV is based on active shutter glasses that deliver separate images to the left and right eyes. However, the market wants TVs that deliver the 3D experience without dedicated glasses across all content. In responding to this, Toshiba has adopted an integral imaging system that reproduces smooth, natural stereoscopic pictures, without any need for dedicated glasses. The company has channeled its initial efforts into personal-use 3D LCD TVs without glasses and is now commercializing 12- and 20-inch models. With these new TVs, Toshiba will seek to lead the market in 3D TV without glasses and to further increase its market share.
Key Product Features
1. The technology of 3D capability without glasses reproduces smooth, natural high quality 3D images

The new Glasses-less 3D REGZA GL1 series employ an integral imaging system and perpendicular lenticular sheet that can display natural and smooth high quality 3D images.

The integral imaging systems is based on the principal of sampling and collecting form several directions the light reflected from an object, and then faithfully reproducing the light through the display to realize smooth, natural images. Until now, conventional 3D technology without glasses has produced a fall off in image resolution and increased blurring[7] that has prevented practical use. Toshiba employs an LED backlit LCD panel specially designed for 3D content that systematically aligns pixels, and has also adopted a perpendicular lenticular sheet in order to realize precise rendering and natural, high quality 3D images.

Toshiba’s technology simultaneously delivers nine parallax images to the LCD panel and controls and optimizes light emission and direction from the center, right and left of the screen to secure a wide viewing angle. The result is optimized display of high quality 3D images whatever the position and angle to the screen of the viewer[2].

This technology is the recipient of the 21st Century Invention Prize for 2010, one of the National Commendations for Invention, from the HATSUMEI KYOKAI, Japan Institute of Invention and Innovation.
2. LCD panel designed for 3D capability without glasses

The 20GL1’s high definition LED backlit LCD panel, specially designed for 3D capability without glasses, has approximately four times the pixels of a Full HD panel, approximately 829 million pixels. It can combine and display nine parallax images carrying information from nine images created in real time from a single frame. It transmits the final 3D image with a resolution of 1280 x 720 pixels.

Toshiba’s LED backlight control system positions 1,440 LEDs directly under the LCD panel to realize bright 3D images. Moreover, each pixel can support the display of red green and blue (RGB) in a layout expressly designed for 3D imaging. Image data from each pixel is replicated nine times and the direction in which they are transmitted is controlled by the lenticular sheet. The result is smooth, natural 3D images that can be viewed from multiple angles without glasses.

The 12GL1 supports the same approach for approximately 147 million pixels and integrates an LED panel that can display 466 x 350 pixels.

The 20GL1 LCD panel is the fruit of research with Toshiba Mobile Display Co., Ltd. This was supported in part under the revised budget for FY2009 from the Ministry of Internal Affairs and Communications for “Research and Development on Glasses- Free 3D Image Technologies.”
3. Newly developed engine designed for 3D capability without glasses

The 20GL1 integrates the Cell Broadband Engine™[6] and the Glasses-less 3D CELL REGZA Engine, newly developed multi-parallax conversion LSIs designed for superior multimedia processing. High speed arithmetic processing creates nine parallax images from original content and converts it to 3D images with real depth, allowing Toshiba to achieve precise rendering of natural, high quality 3D images.

For the 12GL1, the newly developed engine designed for 3D capability without glasses combined with Toshiba’s image processing LSIs and multi-parallax LSIs creates the 3D image.
4. Focus on Environmental Considerations

(1) Integration of LED backlight

The Glasses-less REGZA GL1 Series TVs are environmentally conscious products that integrate energy-saving LED backlighting. The backlights are free of mercury, which occurs at trace levels in cold cathode fluorescent (CCFL) backlights.

(2) Energy-saving features

The 20GL1 offers a number of energy-saving features:
- Power consumption is controlled by maintaining optimum image brightness.
- Automatic stand-by if no command is received from the remote controller for approximately three hours.
- Automatic stand-by mode if, when the TV is set to external input, no signal is received for approximately 15 minutes.

(3) Effective use of resources

All components that use over 25g of plastic indicate the materials used and are designed for recycling. Use of polylactic resin, a biodegradable, vegetable-based plastic 100% derived from corn, contributes to reduced consumption of petroleum and to lower CO2 emissions.

(4) RoHS[8] and J-Moss[9] (Green Mark)compatible

The REGZA GL1 Series contributes to moves toward environmentally conscious products by achieving full compliance with the EU’s RoHS and Japan’s J-Moss.

Sony XBR-LX900 vs Sony XBR-HX909 vs Sony KDL-HX800

Monday, June 28th, 2010

I was confused as to the difference between these 3 Sonys I posted about a few weeks ago. Here’s what I have been able to figure out.

The lowest line is the KDL-HX800. It doesn’t have 3d integrated, and it doesn’t have full-array LED. You’ll need to buy a 3D transmitter separately for about $50.

The next up is the XBR-LX900. It looks to be a KDL-HX800 but with integrated 3d transmitter. (Think of the L in LX as “3d is Lumped in”).

The top of the line is the XBR-HX909. This is the one with truly unique technology: full-array LED backlighting. But, in a move probably to save cost, this one doesn’t have integrated 3D transmitter. Full-Array LED backlighting deserves another post, but basically, it lights up the tv the way a marquee sign is lit – lots of little lights arranged in a grid. This allows what’s usually calling precision dimming – in darker parts of the image, both the LCD turns dark and the LED backlight is dimmed down. This creates really high contrast ratios.

By comparison, edge lighting is more like a florescent light in an office building – the light comes from a single (or small number of) bulb along the edge, but there are screens and filters to spread it out. When the image is supposed to be dark, these LED backlights are still on full blast. Only the LCD pixels themselves are used to try to dim out the image.

The Samsung C8000 series attempted to do a hybrid – the LED lights are along the edge, but they try to dim regions of the image as necessary. The Samsung C7000 does not: the LED lights are on at maximum intensity no matter how dark the image is supposed to be.

If cash were no object, get the XBR-HX909 and add on the 3D kit.

XBR-LX900 Integrated Edge

3D TVs to buy right now (May 2010)

Sunday, May 16th, 2010

If I had to buy a 3D TV right now, I’d want one that’s already worked with a cable provider.

According to the TimeWarnerCable guide for the Masters, there are 3 TVs that worked:

Panasonic Viera TC-P50VT20 (50″ Plasma)
Samsung UN55C7000 55-Inch 1080p 240 Hz 3D LED HDTV (Black)
Samsung UN46C7000 46-Inch 1080p 240 Hz 3D LED HDTV (Black)

The Panasonic TV does not seem to be widely available yet. I could find it on neither Amazon nor shopping.yahoo.com. So I don’t know if the model is already outdated, or if it is too new to be available at retail.

The 2 Samsung TVs look like good bets. Keep in mind that the Amazon SKU does not include glasses- you’ll need to purchase the Samsung 3D starter kit.

But while I was browsing around I also noticed what looked like a newer model.

UN46C8000

compared to the older model numbers, it definitely looks backward compatible:
UN46C7000

So what’s the difference between the two? What does the 8000 suffix mean? And is it worth an extra $200? IMHO, probably. The TV is a bit slimmer (0.9″ instead of 1.0″), and it has a variable contrast ratio technology branded “Precision Dimming”. Precision Dimming is supposed to reduce an effect calling blooming, where the light from an “on” pixel bleeds into an “off” pixel. The leaking light pollutes parts of the screen that are supposed to be pure black. Reviews online suggest it works, so although the TimeWarnerCable manual does not list the UN46C8000, that’s the TV I’d go with. There should be a 55 and 65 inch version coming according to this chart.

Good luck!

Samsung warns 3D TV can cause Seizures, other medical problems

Friday, April 16th, 2010

Samsung warns that 3D TV can cause

- seizures
- motion sickness
- cramps
- convulsions

Probably just some lawyers going overboard, but it would suck if you brought home that 3D TV and any of the above occured.

ESPN 3D Lineup

Thursday, April 1st, 2010

Announcement of ESPN 3D on DirecTV. Interesting points:

  • DirecTV poo poos the idea of one-off sporting events (like the Masters or the New York Rangers game). I don’t know if that’s sour grapes or a focused strategy.
  • ESPN 3D will have 85 events per year (dark other times). Counting it up…
  1. 25 FIFA Soccer Games (basically worthless to most Americans)
  2. 1 X Games 16
  3. 1 2010 college football ACC Championship
  4. 1 2011 BCS National Championship game

So that’s about 30 events right there. The remaining 55 must come from:

  1. college basketball
  2. NBA

Bottom line – we can guess that ESPN 3D is good for about 30 NBA and 30 NCAA games.

Philips WOWvx (lenticular display, no glasses) AVAILABLE NOW

Tuesday, March 30th, 2010

This technology was announced about 2 years ago, and the product was released about a month ago: lenticular 3D TV from Philips.
For Purchase: Philips WOWvx – 42-3D6W02 – 42″
Because this TV uses small prisms in front of the display, it creates an individual image for each eye without the need for glasses. In theory, it’ll only work if you sit still, without moving around, and you have to be sitting within a defined distance from the TV.I can’t wait to see one at BestBuy.

For now, the product appears to be so new that it’s not even listed on the Philips.com website.

but it is promoted on Philip’s youtube site. Here’s their video that demonstrates the old Lenticular “3d postcards” and how it applies to their TV.

Cox joins Comcast b’casting Masters Golf in 3D

Tuesday, March 30th, 2010

Headline says it all. Interesting mainly because this suggests that the organization behind the Masters (Augusta) is actively out there selling rights directly to MSOs, which typically it wouldn’t do. Most “events” would try to sell to a cable network like ESPN and let the cable network manage the relationship with MSOs. It’s possible Comcast made this happen, and then Cox read about it and called up Augusta as well. I’ll speak to a good friend of mine who’s an expert sports to figure this out.

Link to B&C Article

See prior post re: Comcast & The Masters for info on the technology involved. Again, the only piece that talks 3D is the camera, playout, and TV set. The Cable links and cable box in between all talk 2D.

This article also mentions NEP’s SS-3D truck. This is literally a single tractor-trailer that goes around to events to be an on-site production / operations room. SS stands for Super-Shooter, and all of NEP’s other trucks have similarly named trucks, like SS-4, SS-HD, etc. You’ve probably seen them outside sporting events or awards ceremonies tucked away in a far off corner.

Cablevision / RealD deal

Thursday, March 25th, 2010

A sparse article I discovered in Cynopsis before finding the source article from Reuters and actual press release: Cablevision is going to use RealD technology for some of their upcoming in-home broadcasts.

I don’t get this at all. You’ve seen the RealD logo at theaters. I assumed RealD handled the clockwise / counterclockwise circular polarization technology.

I’ll figure out what exactly RealD is providing Cablevision and post it back here… I suspect its more about editing tools.

3D Eye Isolation Technology

Wednesday, March 17th, 2010

The way I understand it, there are 4 ways to beam separate images into your eyes.

  1. Goggles. Each eye gets its own mini TV set, with what’s essentially a microscope to make a screen 1 inch big an 2 inches away appear like a 42 inch screen 10 feet away.
  2. Lenticular Display, in which one monitor shoots 2 different images in 2 different directions. If a TV has about 2000 vertical lines, then there’ll be 1000 little triangular prisms that each cover 2 lines. One line goes to your left eye, the other to your right. You’ll remember this from “3D” or “animated” stickers you got as a kid.
  3. Active Shutters. A display will alternate between showing the left image, then the right image. When showing the left image, the shutter on your right eye will go black. When showing the right image, vice versa. This happens fast enough that your eye doesn’t notice. This is fairly easy for current TV technology to handle, so the cost isn’t that much – pretty soon it’ll be about zero.
  4. Polarization. The left image is showing in one polarization, the right image in an opposing polarization. A polarized lens over your left eye allows only the left image in, and ditto for the right. This technology uses simple optics in the eyewear, unlike the shutter technology, so the glasses are cheaper (cheap enough to be disposable at a movie theater). But the TV display technology is much much more expensive – about $2,000 more (at retail).

According to this article in U.S. News & World Report, the Asia market is leaning towards the more expensive but higher quality polarization technology, whereas the U.S. market is going towards the cheaper active shutter technology.

Masters Golf Tournament: 3D to Comcast and online

Wednesday, March 17th, 2010

This announcement, and watching Avatar, are what made me really interested in 3D technology. Comcast and Augusta are going to broadcast the Masters in 3D. A few interesting points:

- The signal is broadcast over plain old 1080i technology. You can tune in using your non-3D setup, but you’d see 2 panels side by side. It’s up to the TV to merge the panels into a 3d image.

- Augusta is licensing 3D rights separately from the 2D rights, which go to ESPN and CBS. It’ll be interesting to see who provides the commentary / production of the Comcast feed.

- The venue is ideal for 3D, as the ball locations are well defined and predictable, and the crews have time to set up the 3D shots of the greens while the players walk up from their approach shot.

- They claim to broadcast a 3D signal to Masters.com, but I am not sure what equipment you’ll need. I’m on the hunt to sus that out and post it right here, so stay tuned!
