Though OLED is more expensive to make than regular LCDs, it is still a very good display technology because it needs no backlights and has a very high color quality and brightness, and LG definitely appears to have put it to good use when it developed its 31-inch HDTV with a supposedly infinite contrast ratio.

The IFA 2010 show in Berlin, Germany, has entered its second day and IT players have already brought forth a significant number of new or upcoming products.

NVIDIA stole a bit of the spotlight when it released the DirectX 11 mobile GPUs, and PC suppliers also got attention by unveiling multiple new systems.

Now, LG has taken the microphone in order to boast of having created a 31-inch OLED display that has a thickness of just 2.9 millimeters.

Since OLED, through its nature, enables very thin form factors, LG needed to only come up with a suitable layout for the tuner connectivity and all other connectors.

Thus, it set them all in the box at the bottom of the product, leaving only the OLED panel itself to impress with its visual quality.

Not only does the HDTV support resolutions of Full HD 1,920 x 1,080 pixels, but it is reportedly one of, if not the most color-rich and bright of all OLEDs available.

What's more, its maker claims that the contrast ratio is infinite, which should give one an idea of how sharp and clear its images can be.

That said, in order to connect to multimedia players or set-top boxes, the OLED TV has a regular digital TV Tuner, an USB port and a pair of HDMI connectors.

According to Slashgear, LG has two versions of this product on show, the only difference between them being that their stand arrangement and controls are different.

As for availability, they are expected to start selling sometime during the first half of 2011, though their likely massive prices have not been disclosed as of yet.
