| THE BACKGROUND |
|
LG uses technology called WOLED (White OLED) or WRGB (White Red Green Blue). Basically, each pixel comprises four white organic diodes—one with no filter (so it displays white light), one with a blue filter in front of it, one with a red filter in front of it, and one with a green filter in front of it. |
| | | | | | | | | | | | | | | | | | |
In the Samsung model, each pixel houses three organic diodes—one red diode, one green diode and one blue diode. There's therefore no need for any filters. Samsung claims this improves energy efficiency while LG criticises the system since the blue diode could age more quickly than the others. |

Note that this duel isn't based on test data or reviews as is usually the case in our five-star product battles. This is basically an overview of our first impressions after checking out the two 55" OLED TVs for a few hours at CES 2012. We watched the onscreen demos over and over and over again, taking pictures of everything and looking out for faults in the image. We know that the test conditions aren't ideal, or necessarily that accurate. However, based on what we've seen so far, we'll be comparing these 55-inch OLED TVs to find out whether one model stands out as a better option at this stage in the game. |

DESIGN: LG WINS |
|
The LG TV was bound to win really, as LG presented a more developed model, intended to closely resemble the final product that'll end up in stores. The Samsung model, however, still stunk of prototype. Otherwise, there's really not much difference in product design. ![]() ![]() |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
Could Samsung's TV possibly have been prepared a little hastily to get it ready in time for this event? In fact, this TV had been slipped into the casing of another model—a high-end LCD TV from 2010. So as nice as it may look, the final product could still look completely different. ![]() |

GLOSS & REFLECTIONS: DISAPPOINTING DRAW |
|
In Asian markets (and some other regions), everyone wants a super-glossy, super-shiny TV screen. These two South Korean manufacturers seem to be leading the charge in that department, making these TVs as shiny as possible. We, on the other hand, aren't big fans of gloss, as reflections on the screen are a big problem. |
| | | | | | | | | | | | | | | | | | | | | | | |
Lighting conditions in the room will therefore have to be very well controlled to get the best out of these TVs. Ideally, you'll need to watch movies and TV shows in the dark to keep glare and reflections to a minimum! However, the firms' decision is understandable seeing as the first OLED TVs to hit the market will probably sell in South Korea. |
| CONTRAST: LG WINS |
![]() Make no mistake, these two TVs are likely to smash all kinds of records with their contrast ratios. The blacks are so deep that our test equipment will probably end up crashing! After long hours spent inspecting both models, we and the other journalists we quizzed at CES, mostly thought that the LG model looked more contrasted. However, LG has a trick up its sleeve. The edges of objects onscreen are accentuated (a bit too much for our liking) to exaggerate the contrast effect. Plus, WOLED technology displays a brighter image with an equivalent depth of black, pushing up the black:white contrast ratio. |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
![]() This in no way means that the Samsung model disappoints, however. Like we've already said, when contrast ratios head above 5000:1, for the time being, it's hard to establish any kind of preferences. Plus, the very bright white in the LG TV does have a few knock-on effects, as we noticed light tones sometimes looking overexposed and dark areas sometimes flooding together. As it stands, the TV that delivers the most highly contrasted image is, for the moment, the LG. But that doesn't necessarily mean it delivers the nicest looking image ... |
| 2D RESPONSIVENESS: DRAW |

|
OLED screens claim to have a response time of 0.1 ms, but that's not very realistic. In comparison, the best OLED TVs we've tested so far scored a ghosting time of 5 ms. This still makes them the fastest screens we've had in our labs, but it's not quite 0.1 ms ... These LG and Samsung TVs seem to raise the stakes, however. Both manufacturers were sure to include sweeping, travelling scenes and fast movements in their demo videos at CES 2012, which usually show up the slightest problem with screen response times and ghosting. Even after close inspection (and we've got years of experience of looking for this kind of defect) these two LED TVs looked flawlessly impressive! |
|
3D QUALITY: SAMSUNG SCORES |

|
This is another rather one-sided comparison, since LG showcased its OLED TV's 3D capabilities while Samsung didn't. Nevertheless, we still think we'd choose the Samsung model, as LG has used passive 3D technology, which we don't think is suitable for this kind of TV!
If you take off the 3D glasses when watching LG's TV in 3D mode, the black lines caused by passive technology are only too visible onscreen. That's quite frustrating. Plus, a technology crazy user ready to spend £8,000 on the first OLED TV isn't likely to take any compromise on quality. |
| | | | | | | | | | | | | | | | |
Samsung wasn't giving out any 3D glasses for its OLED TV so we couldn't check the quality of the active shutter 3D used in this model. From experience though, we think that active shutter is the right kind of technology for this TV. As long as OLED TVs use Full HD resolution (for about another two years), active shutter 3D will be the best option, as it maintains Full HD resolution in 3D (the overall resolution is halved in passive 3D). From 2014, we'll probably start seeing the first 4K OLED TVs, and from then on, we'll be lobbying for passive 3D all the way! |
| IMAGE QUALITY: SAMSUNG AGAIN |

This rose displayed on the LG OLED TV was supposed to look superb but actually showed how the screen struggles to deal with shading and gradual colour changes.
|
To win over the masses, LG had obviously chosen the most crowd-pleasing settings for its OLED TV on display at CES 2012. Colours therefore looked super-bright and over-saturated, whites were blindingly overexposed and dark areas flooded together. In other words, if we'd laid hands on the remote we'd have changed absolutely everything. Obviously though, we weren't allowed to do that, as LG had voluntarily chosen this kind of image for a more head-turning result—who cares if we found it completely crazy? By looking to create the most striking, eye-catching result, the image in turn looks less natural. Plus, several intermediate colour levels have been lost in areas of colour shading. Images therefore look posterised and colours change in sharp blocks rather than in smooth shaded transitions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
Although it's wasn't perfect (the yellow flowers in the demo were practically fluorescent!), the Samsung TV displayed a more balanced picture that had no trouble reproducing colour shading. We'll even admit that we really enjoyed scrutinising this TV for the slightest fault in shaded colours—the same defect that was often only too visible in the LG model.
Again, Samsung clearly hadn't sought to avoid the usual traps in its demo videos. There was a huge variety of images and colours with plenty of shading but we still didn't spot any problems at all! Another good thing about the Samsung TV is that it clearly has a bigger colour space for a richer choice of shades. This doesn't spoil the picture-quality either. To our eyes, the colours looked superb and very natural. Unfortunately, our camera could only record colours in the sRGB colour space so it was difficult to capture the full, genuine effect. We had much less trouble snapping the LG screen. |

We thought the colours looked nicer in the Samsung TV,
but our Canon S100 camera couldn't capture them properly.
| SCREEN EVENNESS: DRAW |
| Scenes showing a light object moving across a dark background could be seen in both manufacturers' demo videos. As expected, we didn't see the slightest problem with the consistency of image quality across the panel or the slightest rogue light spot in any area of the screen. Both TVs gave superb results, but that was only to be expected, since both models only need to switch off an OLED diode to get a perfect black. |
|
VIEWING ANGLES: DRAW |
![]() |
| | | | | | | | | | | | | | | | | | | | | | | | |
![]() |
| It's another draw between LG and Samsung, as viewing angles were quite simply perfect in both OLED TVs. We looked at these screens from every angle imaginable and the blacks, whites and colours never budged a bit. Until now, only plasma screens were capable of that! OLED technology therefore delivers excellent viewing angles, excellent responsiveness, ultra-high contrast and super-slim screen panels—plasma technology had better watch out! |
|
VERDICT: SAMSUNG FOR A MORE NATURAL IMAGE AND REALISTIC COLOUR SHADING |
|
Although LG's exaggerated, head-turning screen settings may impress some people, we found the picture too saturated. Plus we weren't partial to the overexposed whites and flooded dark zones. So although the two TVs came off even in several fields, the Samsung model wins by a whisker thanks to its more natural picture. We're certainly keen to get both TVs into our test lab so we can check them out in greater detail. We'll be particularly interested to see whether the defaults we picked up on at CES 2012 in LG's model were caused by the screen settings used on the display stand or whether they're caused by WOLED technology—after all, introducing a fourth colour into each sub-pixel does have risks. When Sharp launch its first Quattron TV with an added yellow sub-pixel, for example, it was incapable of reproducing colours correctly. Thankfully, Sharp has put things right since. |
| | | | | | | | | | | | | | | | | | | | | | |
So although colours were a bit over-saturated in Samsung's OLED TV, it still wins this duel by the skin of its teeth. As well as boasting a monster contrast level, it displays colour shading more accurately and more naturally than LG's OLED TV. It's just a shame that there's no release date or provisional pricing information for Samsung's model yet ... |
