OLED-Info: The OLED Experts
OLED-Info has been the leading international OLED publication for over 10 years, with a readership of more than 100,000 professionals a month. We provide a multitude of services to the OLED market based on our extensive and up-to-date knowledge hub and close ties with industry leaders. Our consultancy services include market outreach assistance, display brokerage, business development, financial intermediation and more.
An OLED uses organic semiconductors to create thin light emitting panels. OLEDs are used to create thin, beautiful, flexible and efficient display and lighting panels, and are the future technology of choice.
Recent OLED news:
The Fraunhofer Institute has been developing bi-directional OLED microdisplays for years, and they now demonstrate their latest prototype that features an SVGA resolution - up from VGA in the previous prototype shown in 2012.
Besides the increased resolution, the new microdisplay also features a higher resolution image sensor and an enhanced color depth. Fraunhofer also integrated more components directly into the microdisplay chip, which will make integration easier.
I'm happy to announce our fourth OLED market report, the Transparent OLED Market Report. This report provides a great introduction to transparent OLED panels, both display and lighting ones. It covers everything you need to know about transparent panels technologies, and should prove to be a great guide for anyone interested in transparent panels for their own devices, and also for technology and system suppliers.
Reading this report, you'll learn all about:
The report package also provides:
Apple is set to start shipping the Watch wearable device in exactly one month (on April 24th)- with its flexible plastic-based AMOLED display produced by LG Display. A report from China claims that Apple has cut the expected monthly production rate by 50% - due to problems with the AMOLED display.
The report suggests that LG Display struggles with production yields, and Apple only accepts around 30-40% of the screens produced by LGD. Apple planned to produce about 2.5-3 million Watch devices each month, and this has been scaled back to 1.25-1.5 million devices.
Samsung formed Samsung Display (SDC) in 2012 as a merger between Samsung Mobile Display and S-LCD, in an attempt to streamline operations. There are now reports that SDC is now planning to split itself to two companies - one for OLED displays and one for LCDs.
Samsung Display had a tough 2014 (this was true for many other Samsung operations) and posted low operating profits and even a loss in Q3 as it lost its market leadership to LG Display. SDC now 'blames' its LCD business of "pulling down the entire earnings" while OLEDs are highly profitable. The LCD unit is reportedly lowering morale, too.
The European Commission, under its Horizon 2020 programme, launched a new project called Phebe that aims to develop and commercialize TADF OLED emitters. This three-year project's consortium includes Novaled, Astron-FIAMM, TU Dresden, Kaunas University of Technology, Durham University and other companies and universities.
TU Dresden is focusing on material design using theoretical quantum chemical approaches, and KTU is elaborating synthetic schemes for exciplex emitters and intramolecular charge transfer materials and synthesizing the most promising compounds. Durham will perform photophysical characterisation of the new materials from Kaunus and will also be in charge of elucidating the mechanisms of TADF to feed into the theoretical work of TU Dresden. Novaled will provide best-fit transport and doping material sets, technology and expert know-how on stack architecture.
Both LG Display and Samsung Display are currently producing flexible AMOLED displays, and we know that the two companies aim to increase production capacity in the near future. ETNews posted an interesting article that sheds some light on the company's current plans.
So let's start with LGD, that currently produces plastic-based OLEDs in its Gen-4.5 fab, with a monthly capacity of 14,000 substrates (this more than double its capacity in the beginning of 2014). According to ETNews LGD is building a Gen-6 line that will have eventually have a capacity of 15,000 monthly substrates (much larger than the current Gen-4.5 fab of course). It seems that LGD will begin construction in Q3 2015, and the first stage will have a production capacity of 7,500 monthly substrates.
