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:
According to a report from Korea, Samsung is considering developing Quantum-Dot displays (QLEDs) for TV panels that will compete with OLED TVs. Samsung has failed to commercialize large-sized OLEDs using its direct-emission architecture, and reportedly believes it will fair better with quantum-dot displays.
Samsung is already producing LCD TVs enhanced with quantum-dots films that enhance the color gamut - but these aren't QLED TVs. A QLED is similar to an OLED - an emissive display that uses the QDs as light emitting materials.
The 8" display features Full-HD resolution, 2 ms response time and a contrast ratio of over 100,000:1. The display operates in a wide temperature range (-40 to 85 Celsius).
IHS says that flexible AMOLED shipments reaching about 25 million displays in 2015, or 11% of the total AMOLED market in 2015. AMOLED shipments will grow to about 400 million in 2019, and flexible OLEDs shipments will grow to over 100 million units - or over 25% of the total AMOLED market.
Device makers are adopting flexible OLEDs in smartphones and wearables, to differentiate their products from those that use rigid displays. Flexible OLEDs are especially useful in mobile devices because they are thinner and lighter - and of course they enable new design options.
Next week at SID, Novaled will report on a new Vertical organic field-effect transistors (V-OFETs) that can be used to drive high-brightness AMOLED displays. Novaled says that the new backplane can be deposited on plastic backplanes, and it allows a 4X brightness enhancement compared to reference AMOLEDs.
Vertical-OETs has been first reported in 2011 by the University of Florida. That particular research used carbon-nanotube based backplanes, and it was spun-off to form a company called nVerPix which is commercializing the technology.
LG Chem started developing "truly flexible" plastic-based OLED panels back in 2013, and they recently finished that development effort with sample production already underway. The company now released this video showing the panels undergoing some flexibility tests (including the hammer test):
Currently LG Chem offers samples for $250 each, and mass production of these panels is expected by July 2015 - which will also mean a lower price. Those panels offer 60 lm/W, 75 lumens, a color temperature of 3,000K and a CRI of over 85. The bending radius is 30 mm.
Hong Kong's Truly Semiconductors announced that next month it will complete the construction of the first phase in the company's 4.5-Gen AMOLED fab in Huizhou, China. The equipment will be installed in October, and the production line will begin operation in Q1 2016.
Truly estimates that the new production line, which will be used to make small-sized AMOLED panels, will generate RMB5.3 billion (about $854 million) in annual revenue. The fab's capacity will be 15,000 monthly substrates.
Audi's Head of Electronics Ricky Hudi, says that the upcoming 2017 A8 Saloon car will sport several new technologies - including OLED lighting. Or at least the company is "working on the integration of OLEDs" for the 2017 flagship model.
Audi has been playing with OLED technologies for a long time.Back in 2012 they unveiled three new OLED lighting designs, and in 2013 they unveiled 3D OLED lighting taillight prototypes (developed with Philips and Merck). In 2012 Audi also installed AMOLED digital rear view "mirrors" in their R18 sports prototype cars. It'll be interesting to see if the upcoming A8 will use one of these designs.
