(PhysOrg.com) -- LCD manufacturer LG Display has unveiled its new polarized three-dimensional television technology to 250 participants at a launch press conference in Beijing, China.

The is dubbed FPR for Film Patterned Retarder, which is said to be vastly superior to previous 3D liquid crystal display (LCD) systems. The current system uses a frame sequential method and the display is viewed using liquid crystal shutter glasses (SG). The new technology uses a polarized film substrate in the panel and is viewed using polarized film glasses. Using film instead of glass as a substrate for the patterned retarder panel also cuts the costs of the system considerably.

The new technology reduces the vertical resolution to half that of a panel and produces a near-4K resolution full high definition 3D picture that is extremely sharp and bright. The system was demonstrated at the press conference on an 84-inch display.

The polarized film glasses eliminate the flicker and crosstalk problems associated with . The glasses do not require power from batteries or USB charge, and are also lighter and more comfortable than SG and emit no electromagnetic radiation, which means viewers can use the glasses for hours without discomfort.

A representative of the Beijing Ophthalmology Research Institute presented the results of a comparison of FPR technology to SG. The study included 38 adult subjects, and found that the FPR system produced less eye fatigue than the SG.

Chief Executive Officer of LG Display, Young Soo Kwon, said at the conference that the company was launching the “FPR 3D era” in China and will focus on the new technology because the company believes FPR is superior "in all aspects" to the previous 3D systems.

According to Yang Dong Wen, vice president of Skyworth, a leading company in the Chinese LCD television market, FPR 3D products are clearly different to existing 3D televisions, and their introduction should see China’s 3D television market expand to more than eight million units in the coming year. The FPR system should also boost sales of 3D televisions because it will solve many of the problems in demonstrating 3D TVs in stores, such as dead batteries in the 3D glasses, synchronization errors, and occasional interruptions that occur when several 3D televisions are placed near to each other.

LG Display said the company is aiming to achieve 70 percent of 3D LCD television sales in 2011 with the help of FPR technology. LG (HD) televisions featuring FPR technology are already in production and will go on sale early in the new year, followed by the US in February, and then Europe and the UK in April or May.

Other participants at the conference agreed to cooperate with LG Display to promote the sales of polarized 3D LCD televisions next year. The major companies represented included LG Electronics, Toshiba, Vizio, Skyworth, Changhong, TCL, Konka and Hisense.

It isn't you. It makes no sense because the writer of this article has absolutely no clue about the subject.

He doesn't even understand polarized glasses from his description. This technology will allow people to essentially wear a pair of Ray-bans with clear lenses. More importantly people who wear glasses will be able to get prescription lenses with the polarization or clip-ons for their regular glasses. No more big, heavy, powered things that need to go over your glasses if you wear them, just a light pair of regular glasses for everyone. And since there are no shutters in the glasses the frame rate will be whatever the panel can do and no flicker going back and forth between your eyes. This technology sounds vastly superior. Now all they need to do is eliminate glasses altogether.

Another article also states that the vertical resolution is cut in half but it also shows an 84" LG panel with double the 1080p resolution (3840 x 2160) to evidently compensate (maybe that's the 4k).

In all seriousness, I think it will be difficult to market the technology by calling it "Film Patterned Retarder".

Every time I see these topics I keep thinking: Nice but there is already a better system out there: http://en.wikiped...ki/WOWvx

Philips wowvx. I saw it myself and it is at least as convincing as the options offered today but without glasses! I think all TV manufacturers should instantly invest in this and make it affordable for everyone :P

That WOW technology sounds like it has a very low viewing angle and it may be inherent in which case it won't be acceptable for anything but personal viewing like a computer screen. The LG technology has the same viewing angle as a normal display.

I don't wanna watch TV with glasses anyways...No glass #D seems decades away so until then ill stick with my tv

re: resolution questions
I think the point is that every other horizontal line will be polarized for each eye independently. Presently we base most 3D on flickering the screen at twice the frequency to get one image for each eye. This technology will keep the screen frequency the same but reduce the resolution by half. Thus, if they double the resolution(or more) up front they can maintain the present resolution standards.

just stop watching tv altogether and you will have more time for sex, drugs, rock and roll, etc.

if the resolution is cut in half then it is similar to the sg technology method.... I think they should display both images at the same time, but with differing polarization and make the lenses each sensitive to their corresponding polarization. There should be no need to cut the resolution in half or even have flicker, period.

Cutting the resolution in half is not a problem, resolution is cheap nowadays and higher than the resolution of human eye anyway. Elimination of annoying flicker is worth it.

I dont mind glasses if they are comfortable. Or to put it better, if I have to choose between full-quality 3D effect with glasses and 3D system without glasses but having all other important image parameters inferior, I choose glasses.

The best system quality-wise is still circularly polarised double projector 3D, or shutter 3D with high frequency monitor.

Well perhaps they'll aim for the reality TV audience. We know watching that stuff can make you act retarded.

Everyone here reads this and thinks there cutting the resolution half. Read a little closer. That resolution is now half that of the panel. Near 4K resolution. right now its 2k. the vertical resolution will be double that of a standard high def TV. So therefor odd lines of pixels would be one direction of light and the even be the other. this tech is the future. This is what i'm waiting for. Good 3d Tv's without glasses are far off from being ready.
