Following LG tradition of providing early CES information, the firm has unveiled that it will be showcasing the world's largest OLED panel at 55 inches in size, at this year's Consumer Electronics Show.
The company had already demonstrated smaller 31 inch OLED models at previous events but cost effective production and the production of larger OLED displays had previously been beyond reach, however it's looking increasingly likely that both LG and competitor, Samsung, will be introducing consumer models for sale during 2012, ideally in time for the London 2012 Olympics.
The HDTV that will be on showcase at the CES event will feature a contrast ratio of over 100,000:1 and an extra-wide colour gamut. Unlike LEDs or Plasmas, OLED displays emit light directly from the diode as oppose to passing through a layer of liquid or gas first, removing completely the effects of image ghosting. A back-light is also not necessary with OLED technology and so contrast ratios are little exaggerated with almost perfect black levels under real scenarios. This lack of intermediary elements allows the displays to run efficiently and in less space, with less cooling, meaning thinner panels; LG's CES panel is to be thinner than a pen at 5mm thick, thinner than the latest Kindle E-Reader.
LG has also opted for the use of White OLEDs (WOLED), which produce a white-light from red, green and blue diodes vertically, meaning that they are stacked and so only the end white-light product is visible. This allows for smaller, crisp pixels, with a lower rate of defect; colour is handled by a simple filter layer that sits just below the TFT base panel, offering a simple, cost effective approach, that can deliver identical colours over a range of angles.
All very exciting! We wonder, as well, exactly what Samsung will pull from its sleeve at the event, unlikely wishing to be upstaged.
