All the OLED smoke from the recent CES event has settled and it appears only two manufacturers, LG and Samsung will offer their beautiful OLED TVs in 2012. No specifics regarding price and actual DOR have been released to the public however the information regarding the technology have been reviewed and it appears the OLED TV from LG and Samsung is quite different from one another.

LG - I will begin with the LG OLED TV. This TV incorporates the use of White OLED technology. The configuration of a four sub-pixel arrangement of Red, Green, blue, and White (8.29 million pixels) is displayed through a color filter which dramatically enhances color precision. An oxidized TFT (Thin Film Transistor) is used as the backplane. This method matches the international standard of natural color range (BT.709) to produce colors that are superior to the old RGB-type and is most evident with images that require extensive use of the blue pixel. Idemitsu Kosan, the world's best blue-pixel maker for OLED technology, is currently contracted with LG. Color deterioration is non-existent during off angle viewing.

Samsung - uses a three-color pixel arrangement of Red, Green, and Blue (6.22 million pixels) colors without the use of a color filter. Colors may appear vibrant however the color may deteriorate when viewing slightly off angle. A Low Temperature Polycrystalline silicon (LTPS) is used as the backplane as with their AMOLED displays on their mobile phones. Due to the current limitation on the size of the excimer laser used for LTPS, production costs to produce the same 55-inch OLED panels are higher than LG.
Design
LG - The LG OLED TV display is almost half the size of the iPhone in terms of thickness (4mm vs 9.3mm) and is also equipped with a near-invisible 1mm-thick bezel. The approximate weight of the set is 16.5lb and contains no hazardous materials.

Samsung - Although the Samsung OLED TV is not the slimmer of the two, @ 8mm thick with a 5mm bezel, it is much thinner than current LED TVs. The approximate weight of the set has not been released however Samsung claimed to be “significantly lighter” than 18 kg at CES 2012.This set contains no hazardous materials.

Both of these TVs showed tremendous potential at the beginning of this year. The passionate pursuit of perfection can be implied to both of these companies however when each are viewed under the microscope, the LG OLED TV appears to be much more promising.
