LG vs Samsung, passive vs active: 3D ping-pong, anyone?

Samsung 3D press ad

Been following the spats between LG and Samsung about the relative merits of the former's passive 3D technology, and the latter's dedication to active 3D? If so, here's the latest update from the all-Korean 3D ping-pong championship…

LG's been making the most of its survey showing most people say they prefer the company's passive-glasses 3D over the active technology used by Samsung, Sony and Panasonic (oh, and in some LG plasma TVs, but let's overlook that one for now, eh?)

Last week it ran ads in the US press saying 'Hey, Sony and Samsung – Better stick to 2D', leading Samsung to counter with its own survey showing just how much of a grip it has on the US 3D market.

John Revie, boss of the company's visual display marketing in the States, told trade magazine TWICE that for the period from May 22nd to June 18th, Samsung had a 61% share of the US 3D TV market, building from a 50% share in April-May.

He also pointed out that it's doing its bit to make 3D glasses more affordable, thus answering one of the main criticisms from the passive 3D camp: US buyers of its 3D TVs will get two pairs of glasses free, and the prices on extra pairs of glasses have been reduced to $50 (just over £30).

Samsung is also running ads in the specialist press in the States emphasising what it sees as the superiority of its active 3D over the Film-type Patterned Retarder technology being promoted by LG.

Meanwhile, back in Europe…

LG has answered one of the criticisms of passive 3D – that it's not full HD – with the announcement that Frankfurt-based VDE, one of the largest testing and standards organisations in Europe, has certified its Cinema 3D TV as full HD in 3D mode.


The president and CEO of LG's Home Entertainment Company, Havis Kwon, says that 'This latest certification proves beyond all doubt that LG’s Cinema 3D TVs, which already provide the most comfortable 3-D viewing experience, deliver 3-D in full HD.

'We’re pleased to say we can now put this debate to rest.'

The 'debate' came from Samsung, which was suggesting that the FPR-type passive TVs didn't reach full HD standards. As LG puts it:

'The dispute over LG’s TV had centered on whether the company’s Cinema 3D TVs truly qualified as Full HD, defined as a horizontal image containing 1,080 lines of definition. LG’s Film Patterned Retarder (FPR) technology, used on the Cinema 3D TVs, creates the perception of 3D depth by delivering two 540 line images, one for each eye, that are then combined via the glasses to create a unified 1080p image.

'The ruling from the VDE delivers the clearest affirmation to date of the validity of LG’s FPR technology, and Cinema 3D TV has already received a string of endorsements from other institutions and agencies.

'The China Electronic Chamber of Commerce ruled that both the vertical and horizontal resolution of LG Cinema 3D TVs meet the 1080p TV standard, a position that allows LG to use the Full HD logo in China.'

Greener 3D, too
Oh, and just to keep the war of words cooking, LG has also announced that two of its 47in TVs have become the first 3D models in Europe to receive the Carbon Reduction Label from the Carbon Trust, indicating their green credentials.

LG 3D TVThe company says that 'Through innovations such as Edge LED and the Local Dimming System, the 47LW5500-ZE and 47LW550T-ZE use more than 30% less energy compared to conventional models in the same class.

'And with Smart Energy Saving, LG’s own energy reduction technology, the LCD TVs further reduce power consumption by up to 70%.

'This translates into a reduction of 795kg of carbon dioxide emissions over the average lifespan of a TV in Europe (7.2 years), the equivalent of 250 litres of diesel fuel.'

So, either that brings to an end the 3D format battle between the Korean giants, and we can all move on, or it's time to say 'Your move, Samsung'.

Anyone want to take a wild guess on which it will be...?

Clearly the winner will be determined by the consumer

i personally sold my Samsung 55inch TV and purchased an LG simply because i couldnt stand the flickering of active. The Passive glasses are indeed lighter cheaper and easier to watch 3D through.

Samsung are a brilliant make of TV and they will in the end choose Passive. lets face it. who still makes HD-DVD players instead of Blu-Ray. reminds me of the VHS Beta war...

I feel so sorry for Sammy, in this 3D technology battle, they clearly lost the war here. A lot of reviews, analysis, theories already prove that active 3D cannot be the contestant for Passive 3D. Sammy is on top of its pyramid for some reason, but as long as 3D tv goes, unless they adapt passive technology, I don’t see the way they can win this battle. Way to go LG!

Surely as the Olympics approaches fast, the headline should read 3-D Wiff-Waff anyone?

Surely using the same logic, you could then argue that active sets have 2,160 "lines of definition" . . . 


The way I understand it, not really as active sets deliver 2 alternate images. The LG delivers 540 lines to the left eye and 540 lines to the right eye at the same time. Presuming it's the same image, only a slightly different angle, far as I'm concerned it's still 540 lines. An active set delivers 1080 lines to each eye in turn - 1080 lines of info. Full HD.

It's a jiggery pokery with numbers. A bit like saying a BD film is 16:9, 2.4:1. It's 21:9 - the black bars weren't a part of the director's vision. You could argue there's not 1080 lines of film being shown so the film isn't really 1080p cos some of the lines are blackness?
