Today Korean giant LG Electronics showed off a range of premium sound and picture products which will be appearing in coming weeks.

The highlight was its new W series OLED TV. Now, we know that one of the virtues of OLED is that the panels can be very thin since each cell produces its own light, rather than sitting in front of and controlling the transmission of light from a separate backlight. But of course there are structural issues here. Make a large panel too thin and there’s a good chance it’ll shatter just when lifted by its corners. The W Series TV is just 2.57mm thick. Let’s say one third of the thickness of a typical smart phone.

Do It With Magnets

How to support something like that?

LG’s solution: affix it to a wall bracket. With magnets. Of course.

Naturally the wall plate adds its own thickness to the whole, but nonetheless that whole remains at just four millimetres thick. LG says that the “W” naming this series stands for wallpaper, or window, since that’s somewhat like its appearance, almost flush on the wall.

There’s no room for anything beyond picture production in the panel, so everything else – panel driver, inputs, TV tuner, sound – has been offloaded to an external, high performance sound bar. One that delivers Dolby Atmos sound using speakers on its top to produce a height effect.

Given the design of this panel, there is no option for standalone mounting. It’s wall or nothing.

If offers, it just about goes without saying, ultra high definition resolution, a virtually infinite contrast ratio, High Dynamic Range picture support and Dolby Vision. But more on that shortly.

As the premium model of the premium models, the LG W Series is far from inexpensive. The 65” LG Signature OLED65W7T – the only one slated for release here so far, will be on sale for $13,499 when it appears in the first week of April.

Several other OLED models more conventional in design are also coming up: the next-most-premium OLED65G7T ($9,099 – second week of May) and the more affordable E7 and C7 series, which are both available in 65” ($7999 and $6899 respectively) and 55” ($5199 and $4099).

Notable by their absence are any curved models. None will be launched here. Good riddance, I say. The curve made them look stylish but offered nothing in the way of improved picture quality except, perhaps, for the one person seated right in their “sweet spot’’. To me, curved TV screens were one of those things that they did because they could, not because they offered any inherent advantage.

Super UHD

LG still sells regular high quality LCD/LED TVs, with its premium non-OLED range called Super UHD. These are marked by a new screen coating called Nano Cells. Particles around one nanometre in size provide more precise filtering of wavelengths, says LG, providing greater colour purity. They are also said to provide improved anti-reflection performance.

Where I was situated at the launch I was unable to make a judgement on the first point, but the window beyond the TV gave a good real-world demonstration of the reflection performance. Sitting next to the Super UHD TV was a regular LG model. The light from the window was angling across both screens. At one point I could not even tell if the cheaper TV was displaying an image while it was always clear what was on the Super UHD TV’s screen.
