Panasonic, Samsung, Sony and XPAND 3D Join Forces in Full HD 3D Glasses Initiative'

08 August 2011 Four Companies Will Seek Development of Joint Licensing on 'BLUETOOTH® ENABLED RF' and 'IR' Consumer 3D Active Glasses


Panasonic Corporation, Samsung Electronics Co., Ltd., Sony Corporation and X6D Limited (XPAND 3D) today announced their intent to collaborate on the development of a new technology standard for consumer 3D active glasses, under the name, Full HD 3D Glasses Initiative.

This could be the start of a widely accepted universal standard for 3D active shutter glasses but I do wonder why there are only three CE companies. If this was a serious attempt to create a universal standard why couldn't they convince more CE companies to join? Why didn't they go along with the CEA standard that is currently being made? Will this standard deal with the issue that CE companies use different color tints on their 3D active shutter glasses ?


Also I find it a bit hard to trust XPAND as a company. When they sold their so called "universal" 3D active shutter glasses they never mentioned the issue that CE companies use different color tints on their 3D active shutter glasses. An issue that even now I could not find mentioned on their website . Also one of the main points of having a universal standard would be to allow for cheap mass manufactured 3D active shutter glasses from a wide variety of competing companies. Does XPAND intend to allow this? It is not just an issue of how hard it is to obtain a license to make 3D active shutter glasses for this standard but also how much the license fee will be.


I do hope to see a widely accepted universal standard for 3D active shutter glasses. Without more information though I can't tell if this standard will be it.

The Tint issue - does that exist with 2011 Active Glasses 3DTVs?

Quote:
The license of today’s newly announced Full HD 3D Glasses Initiative is targeted to be released in September 2011, at which time the development of new standardization-applied active 3D glasses will begin. Universal glasses with the new IR/RF protocols will be made available in 2012, and are targeted to be backward compatible with 2011 3D active TVs.

Sounds more like an attempt to corner the market than standardization.

The question that came to me is: What if the TV makers change their protocol on new TVs, will their old glasses still work on the new TVs? So if you have 6 pair of 2010 glasses from TV maker x, will they work on 2012 TVs from that maker?

Samsung has already done that. They went from IR to bluetooth. New glasses don't work on old TV, old glasses don't work on new TV.

It would be good to know whether the tint issue exists with the 2011 3D active shutter glasses from Panasonic, Samsung, and Sony. I notice that you quoted the statement about this standard being "targeted to be backward compatible with 2011 3D active TVs". I wouldn't put much hope on that statement though when it comes to the color tint issue. After all XPAND considered their 3D active shutter glasses back in 2010 to be "universal" even with the color tint issue. Also here is an article from HDTV Magazine about the color tint issue.

Can you compensate by adjusting the tint control or other picture parimeter controls on the TV?

If there are separate picture controls for 2D and 3D that might be possible. Still that is only possible if all the 3D active shutter glasses that are used with the 3D display have the same tint.


What makes the tint issue a joke is that it was likely done on purpose by CE companies to make money from accessory sales. Samsung chose a greenish tint while Panasonic and Sony chose a yellow tint but with a different degree of tint. I am somewhat skeptical of XPAND but at least they chose a neutral tint with their 3D active shutter glasses. Currently though I don't know if a neutral tint will be required with this standard.

When my Panny was ISF calibrated by a pro, he used the Panny glasses attached to his meter, so if the glasses tint changes the calibration should be re-done with the new glasses. Even this method does not compensate for the 50% light loss when the glasses are strobing.


Bottom line is that 3D calibration is only a marginally effective endeavor. Small differences in glass tint are the least of the worries.

The light loss due to the glasses is SOP for glasses based 3D (active or passive). If your transmisson rate truly is 50% - that is really good. Some go as low as 20% meaning 80% of the original light is lost to the eyes

All they talked about was the Comm (IR/RF/BT). We will have to wait for the standard to be published.

True, and though I have some concerns about this standard I am hoping for the best. A widely accepted universal standard for 3D active shutter glasses wouldn't just bring down prices through competition. It would also allow for long term upgradability with improved 3D active shutter glasses (lighter, less light loss, faster response time, etc...).

Four More Companies Join 3D Glasses Standard

Quote:
The group, which was founded by Panasonic, Samsung, Sony and Xpand 3D earlier this month, aims to create a standard for 3D active-shutter glasses using Bluetooth technology. Royal Philips Elecronics, Sharp, TCL and Toshiba said on Tuesday they will support the initiative as well.

Great news, and it does look like this will be a widely accepted universal standard. For anyone wondering the TCL Corporation is a Chinese CE company that is the sixth largest producer of TVs in the world. Also the logo for the "Full HD 3D Glasses" standard can be seen in this press release .

 

[Richard Paul]

As of November 1st the Bluetooth protocol is now part of the license program which can be seen on the Full HD 3D Glasses website . The royalty information has also been added to the website and can be seen in the License Program section .
