World's Largest 55 inch OLED TV - From LG

LG has developed the world’s largest 55 inch OLED TV. CES (Consumer Electronics Show) is to be held in Las Vegas. It is where 55″ OLED TV from LG will be displayed on January 9, 2012.

Other electronics companies taking part in CES 2012, have not declared so openly their possible products for the show. But, it is LG to claim to produce the world’s largest 55 inch OLED TV.

About OLED

OLED stands for Organic Light Emitting Diode. An OLED is a special type of LED (Light Emitting Diode) in which, a film of organic compounds (called Emissive Electroluminescent Layer) when given electric current, emits light.

An OLED display panel is technically better than LCD panel (based on liquid crystals). Its signal speed is 1000 times better than LCD’s and it also consumes less power. It doesn’t require special backlighting, so its screens are comparatively slimmer than LCDs. As for now, this is the best display technology available with extremely high resolution and brightness.

Earlier sometime ago, organic light emitting diodes were only used in small handsets, due to their inadequacy for large displays. Now, the technology seems to improve with time to extend their capacity to TV and Screen displays.

Features

The TV panel is ultra-thin and executes superior video quality due to its extremely high contrast ratio of over 100,000:1. Also there is no after-image because the reaction velocity and signal speed are very high.

LG OLED Technology

LG has utilized WOLED (white OLED) along with colors to minimize errors for superior clarity. The WOLED prototype is super-thin with thickness only 5mm.

In small OLED panels available now-a-days, normally LTPS (Low Temperature Poly Silicon) is used as backplane. But LG has tweaked the technology. For its backplane, the display panel has utilized Oxide TFT technology. It is very similar to the current TFT process with a very simple and basic difference of replacing Amorphous Silicon with Oxide.

Now, LG has bigger plans to sell the OLED technology to masses and to emerge as a quality TV and Screen solution.

Uncertainty

Technology experts expects OLED as the TV display of next generation. This technology is facing challenges due to its very high cost and its inadequacy for large-size displays. In the current falling economy, to survive OLED technology must have to be smart enough in both cost and quality.

As yet, LG has not provided any information on availability and price.

LG Speak

In the words of Dr. Sang Beom Han, CEO and Executive Vice President of LG Display :

Our objective has always been to actively define and lead emerging display technology markets. Although OLED technology is seen as the future of TV display, the technology has been limited to smaller display sizes and by high costs, until now. LG Display’s 55-inch OLED TV panel has overcome these barriers.
