LCD-displays will not disappear but in forthcoming years we will see amoled displays in more and more portable electronics.

LCD-displays will still be the most common display tech where it is not needed to show adcanced graphic and where the display shall show same figures and picture for a long time.

LCD-displays will also still be most common in larger displays forthcoming years because of that larger amoled displays will still be not made in larger volymes.

Sasmung want to be the worlds largest Amoled display manufactorer so they invest billions USD in new factories for making larger volymes of Amoled displays.

Samsung and LG will invest together $17 billion to 2016 in new manufactoring plant facilities according to the amoled news items sources.

Amoled or WOLED=White oleds is a very interesting new field for as light source that many companies like GE (General Electric) invest large sums of money in today.

Because WOLED can exchange flourescent light in all types of uses especially interesting in cooling cabinets in supermarkets because WOLED is not emitting heat at all.

WOLED can also be ROLED or Red oled, all this new light sources will come in 3-4 years that will be a new revolution in electric light sources and of course very interesting for architectures and commersial signs.

You obviously are an amoled expert. But you also know LCD contrast ratio keeps being improved every month when new screens come out, at some point consumers don’t see the difference or just don’t care to pay the difference. LCD is getting so crazy cheap and so crazy high quality, I don’t think amoled makers are able to or even interested to try to aim at an even lower price, amoled is just a temporary way for big companies like Samsung or Sony to differentiate on the high-end, both of which still have their full LCD manufacturing capacity in place and they can easily fall back to LCD when it becomes obvious for them.

Oleds emits light by them self you see OLED=Organic Liight Emitting Display because of this when every subpixel emits light from these organic polymers.Because every subpixel emits light in oled displays they are very good in strong sunlight.

Dupont and CDT and some other developer of oled displays have developed Roll-to-roll technology there large Ink Jet printers print out oled displays, where every subpixel is a dot in the Ink Jet printer nozzle which work with piezo electric technology.
CDT was before owner of one of these developing companies which is developing Ink Jet printing of future oled displays, the companys name is Litrex.
Ink Jet printing of displays can also make LCD displays with the same tech.

Samsung,LG,Sony,AU Optics,CMEI will not be the only large makers in futuure of amoled displays.

Amoled where am=Active Matrix similar to TFT for LCD displays but in amoled displays it is not only one thin-film-transistor for every subpixel it is two thin-film-transistors for every subpixel.

Amoled displays have also much higher contrast ratio because one switch of subpixel is totally dark because every subpixel in an amoled display
is a very small light source but in LCD-displays dark subpixels is not switch of subpixels it is only the LCD that works as a shutter for the external light source behind the display or at the edges of the display as in LCD-displays in mobile phones.

I’ve heard Pixel Qi and others in the LCD business talk about plastic based screen instead of glass. I don’t see why amoled should get plastics any sooner than LCD.

LCD is maybe even 2 billion screens per year now. Amoled is a good business for Samsung today because they can keep it to themselves and differentiate against other expensive phones, but my guess is it won’t last for very long. If I had a choice between Pixel Qi and Super AMOLED Plus I would choose Pixel Qi for sure, for one, having up to 5x more battery life is very important, being able to read books comfortably and use the screen outdoors is also.

But it is not only Samsung which will be large maker of amoled displays forthcoming years.
Kodak oled division has been sold to LG.
Kodak and Motorola were two of the early beginners in oled research in the 1970th.

Even if it was prof.Sir Richard Friend from Cavendish College at Cambridge University who find out polymer based oleds and developed it and took patents in 1990.

Except Samsung and LG, taiwanese companies like CMEI and AU Optics.

American Duponts is one of many developers of oled displays that will never make the displays by them selves and jsut be like the company as Prof.Sir Richard Friend started i Cambridge CDT=Cambridge Display Technology as japanese chemistry company Sumitomo aquired in august 2008 for $285 millions.
Sumitomo Chemical Company had been long-term partner with CDT in developing amoleds so it was natural way in business that Sumitomo aquired CDT.

Samsung oled-tech business is Samsung licensing from american company and developer of oleds Universaldisplay.

So, it forthcoming years it will not only be one or two big companies that will make millions of different sizes of amoleds, it will be massive of companies in some years ahead.

Dupont have developed technology for making amoleds with Roll-to-roll tech where both substrate and whole display will be made in plastic thinner than 1mm on flexible substrate.

With Roll-to-roll process for making amoled displays with graphene electrodes it will be possible to make displays that will be totally transparent when no current is on the subpixels and pixels so amoled displays can be partiell or totally transparent when no current is on the pixels.

In portable computers it is the processor and the display that are the most expensive parts of the computer.

Pixel Qi will not be the next display technology in larger volymes because even Pixel Qi needs glass substrate.

For portable computers and Smartphones cracked displays is today a big problems jsut because LCD-displays are made on glass substrate and must be made of 2-glass layers son the LCD-display can emit light because LCD must have an extra light source for being emitting light.

They sell millions of phones, so R&D costs amounts to few cents per phone. I think 25% profit per phone is kind of a decent thing. Right now, those companies try to grab as high profit margins as they can while they think the consumers still think this is attractive enough to pay $2500 on 2-year contracts, and the makers are kind of also required to do it from the carriers, the carriers require a very high unlocked price to not compete with the crookish subsidized price.

Maybe Samsung, HTC, Motorola, Sony-Ericsson, LG all can have a Nexus Prime launched on the same day with Ice Cream Sandwich. Who knows, I would guess with 25 thousand phd software engineers, Google can afford to help these giant smart phone makers release new software on new phones at the same time instead of working only with one manufacturer at the time and pissing off all the other ones.

5 huge LCD manufacturers make over 1 billion LCD screens per year. Samsung is nearly the only one and they are making something around 10-20 million AMOLED screens per year. Surely that affects the price. But since Samsung pretty clearly though indirectly prevents all other smart phone makers access to this screen technology over the past month (HTC and Apple surely have asked), Samsung only needs a production capacity around 50 million screens per year to be the dominant smart phone maker (in front of Apple, Nokia and all others) and use their own screen to differentiate with all competition that are forced to stay on LCD.

With production capacity of over 1 billion LCD screens per year, I expect the LCD camp to always advance their technology to similar if not better usability levels than Super Duper AMOLED Times Plus, by using technology like Pixel Qi for backlight off usage, sunlight readability, indoor readability, those things can become required features pretty quickly.

I heard that the Nexus Prime would be manufactured by HTC
so the desgin could be more closer to HTC smartphones. About the selling price, I think that you forget to condider all the money spent to create the device and to adapt/maintain its software. Even if i agree with you that they could low down the merges, they can not sell the device only 10% more expensive than the manufacturing price.

Amoled dsiplays is not more difficult to manufacture but Samsung Mobile Display can not make so many amoled displays as they have declared earlier this year because even Samsung need litographic technology from japanese Nikon.Nikon have also got problems to make machines for the semiconductor industry after the earthquake,tsunami and Fukushima disaster and lack of electricity because of that.

Amoled displays need fewer producing steps than lcd-displays need so amoled displays will be cheaper to make in the future with plastic substrate instead of glass as substrate (as the first generations of amoled display making will be made on).

Prof.Sir Richard Friend from Cavendish University in Cambridge UK have his patents in polymer oleds that expired at the 4th of April 2010, Mr.Richard Friend was one of three prize winners of the Finnish Millenium Prize (also called for the Finnish version of the swedish Nobel Prize but the Millenium Prize is only for technological inventions).

Larger companies are not willing to pay licens costs to patents owners, if the big companies can´t stole a patent they rather wait for the patents to expire in time, 20-years technical patents last and 20-years will it take before great inventions will come to the market just because the unwillingness to pay licens for patents.

Prof.Sir.Richard Friends patents in polymer oleds is they only cause of, why we still have not seen larger amoled displays in manufactoring!
