OLED is the future of TV sets,  At present it is LCD's  reign, though not for long. But in present  Only four companies, Samsung and LG have manufactured OLED  TV sets. In 2012, Sony and Panasonic had announced that they will jointly manufacture these.  

Science behind it:        

 OLED screen  previously  were used in cellphone and digital camera, but their manufacturing cost kept them from being  produced as big TV screens . 

OLEDs are semiconductors made of layers of organic material. They create light in much the same way as a traditional LED does. Manufacturers make the screens by spraying organic films onto a substrate, typically glass or plastic, printing out patterns the way ink dots are printed on paper

 Why it is Better?  (Here LG is used as example)
  
  An LCD TV needs a backlight, but an OLED’s pixels emit their own light. So turning them off makes them go completely black, with none of the afterglow you’d get from phosphor-based technologies—like cathode ray tubes or plasma displays  or even from an LED-backlit LCD, which can dim only regions of the screen, not individual pixels. Being able to create a really black, greatly improves picture quality


LG has announced that its first 55-inch OLED TV is just 4 millimeters thick and weigh 7.5 kilograms. A comparable 55-inch LCD TV from LG is nearly 4 centimeters thick and weighs about 22 kg. 


 Prices:
 LG uses a technology known as WOLED (White OLED with colour filters), for which the average price of one display comes to $3,600 (around £2,250). Whereas Samsung uses a different technology, called RGB (Red, Green and Blue) OLED, for which the average cost of manufacturing one unit becomes $7,300 (approximately £4,550).

Neither technology is especially cheap, yet the difference in production cost is evident, Samsung’s curved OLED TV is available for just €7,999 in Germany, compared to €8,999 for LG’s.


 Prices are insanely high, it could be better if prices made low, What do you say ?
