OLED are effectively light emitting diodes made from semiconducting organic polymers. It's able to operate due to the phenomenon of electroluminescence. It has an organic dye which consists of exciton states, these consist of an excited electron and a hole or empty state, When the hole and electron combine a photon is emitted and light is produced.
One of the significant point when compare OLED with LED is that in colour accuracy. OLED TVs use a much simpler process to create the required colour, resulting in much richer and true clours than LED.
When comparing OLED technology with either LCD or Plasma display, it produces much larger display with more scalable production process than LCD and Plasma, and it has improved range of colours and brightness compare to LCD and Plasma displays.
jbond--yes, a 55-inch OLED screen is very impressive. I'm looking forward to seeing more analysis on how this was accomplished. LG sort of came out of the box and leapfrogged (is that a verb?) everyone else size-wise. I hope this stimulates the TV/big screen market--while I am enjoying the low prices we pay for an LCD now, manufacturers are having a rough time.
After hearing about this OLED breakthrough a few days ago, I was excited. This is what my husband has been waiting for. Of course the price is way out of reach at the moment, believed to be around $5000. If LG and Samsung have solved the display issues of the past, this will mean these larger OLED TV's should become affordable in the next few years.
Hi Himan: On one hand, manufacturing OLEDs should be easy becuase you can spray the diodes right onto a substrate. But there are still limitations to the materials which makes investing in large-scale OLED manufacturing operations risky. I also don't think there are a lot of companies making OLED production equipment--unlike LCDs, which are manufactured like semiconductors--there is little demand right now. I'm not sure why LEDs are so expensive. I'll try to find out
i am amazed after reading the IHS iSupply report about the market forcast. How do they come up with the number like the expected demand for the upcoming years? They do not have any previous data to compare with for OLED or AMOLED.
The price of LED display is still high. If OLED/AMOLED technology is realtively simple then why is the price higher than LED? Is it due to the fixed cost incurred during the research or due to some other reason?
@Jacob: good questions. The most significant difference is that OLEDs are their own light source--you don't need a backlight or secondary light source. So as a power-saver, OLEDs are ideal. I'm not sure about organic--at least in the sense that we usually use the term--I think it has something to do with the way OLEDs operate rather than the fact they are 'green' or natural. LEDs still require some kind of backlighting, so they draw power, etc.

Peter Drucker famously said "Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window." Yet in the razor's-edge world of electronics—with a lean supply chain and just-in-time demands—the need to know the future is vital.
While no one really can accurately predict the future, we can take guidance from another Drucker saying which is the best way to predict the future is to create it.
You've heard the saying "the No. 1 supply chain risk is your people." That hasn't always been the case. But today's complex global supply chain requires a new type of multitalented employee. It's one who understands, finance, marketing, economics, is savvy with technology, graceful with relationships and can think analytically.
Where are these people? Are universities properly preparing the next generation supply chain professionals? How do train your existing workforce for these new, demanding positions?
Brian Fuller, editor-in-chief of EBN, will lead a 60-minute Avnet Velocity panel discussion that will ask and answer these and other questions swirling around today's supply-chain talent challenges.
