Dr. David Fyfe, President of Fyfe Consulting, in a paper entitled, P-OLEDs (Polymer OLED)-How Close to Commercialisation asked, why should OLED replace LCD
Here is what Dr. Fyfe said, "With OLED, power is in direct proportion to the amount of light required," further, "black draws no power." It is all about energy efficiency as LCD throws away a lot of light in the process of producing a picture. And light is energy and at the end of the day, energy is money.
The key reasons that Dr. Fyfe stated for why OLED will eventually prevail, in case you hadn't noticed market ructions with content types that favor one screen or the other, was that, "OLED has a 180 degree viewing angle, high intrinsic color saturation, ultra thin form factor, very fast refresh rates, very high contrast rates, it is energy efficient and the total bill of materials is less than LCD."
David Fyfe sees materials challenges with the 'lifetime of blue and green which is also faced in small molecule OLED.' Just in case it is the first time reading about OLED, the materials under discussion are phosphor and polymers.
Chang-wook, Han, Chief Research Engineer of LG Display, discussed OLED development problems in terms of type of problem in they present for mass production and said that, "scalability, mobility, stability and uniformity are key. This impacts efficiency, reliability and mass production."
David Fyfe was one of the few speakers to make mention of the content market highlighting the benefits of OLED to consumers through 3D, though it is clear that OLED has an energy savings advantage. The content market move was said to have, 'accelerated commercialization.' This may well have been direct from knowledge gained in the process rather than any pull factor for market increases in purchases.
In some countries there is also a legislative push factor for consumers that Dr. Fyfe said favors OLED. Legislation tends to do the trick if consumers aren't switching fast. With multiple television households and economy factors considered alongside switching costs the plan wants, a little, for a TV recycling program that rewards. The market switch may well be underway and unstoppable though as the discussion was POLED not simply OLED and the P might as well stand for progress.
The speakers were referenced from their June 2010 papers presented at the International LED and OLED expo, seminar and forum in Seoul, Korea.
