OLED-Info: the OLED experts

OLED-Info has been the leading international OLED publication for over 10 years, with a readership of more than 120,000 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

Tianma demonstrates its flexible and foldable AMOLEDs

Tianma demonstrated its flexible and foldable AMOLED displays at MWC 2018 earlier a couple of weeks ago, and the following video shows a nice tour of the displays at Tianma's booth.

The first display you see is a 5.5" FHD flexible AMOLED (on a Polyimide substrate). There's a long discussion there about creating a foldable Phone around that, but beyond that it is nice to see Tianma's flexible OLEDs in action.

AUO developed a transparent 13" OLED for AR applications

Taiwan's AU Optronics (AUO) developed a 13-inch 100 PPI transparent OLED display, specifically for AR applications. This is a highly-transparent display - with 68% transmittance.

AUO transparent OLED prototype

AUO 6" transparent OLED prototype (2011)

To achieve such high transparency, AUO optimized the TFT array layer stack, the OLED cathode pattern and the encapsulation. This is the first transparent OLED AUO has developed since 2011. It will discuss this new display at SID Display 2018 - and will hopefully demonstrate it as well.

Visionox's latest 7.2" foldable OLED prototype can withstand 200,000 folding cycles

Visionox developed a 7.2" foldable AMOLED display, and has tested its reliability. Visionox says that even after 200,000 folding cycles, the display still showed good reliability. Visionox also performed extensive surface hardness and ball/pen drop tests on this display.

Visionox will discuss the reliability and failure mode analysis of its foldable OLEDs at SID Displayweek 2018 in May - and will also hopefully demonstrate this new display. Visionox performed the tests on a display module that included the AMOLED panel, a touch layer and a thin circular polarizer layer.

LG's Crystal Sound turns flexible OLED lighting panels to speakers

In early 2017 LG introduced its Crystal Sound OLED technology, which vibrates a flexible OLED display panel and turns it into a speaker. This technology can create seamless OLED TV designs that do not require speakers.

LGD Crystal Sound OLED lighting speakers (L+B 2018)

In a very natural move, LGD announced today that it will bring the Crystal Sound technology to its OLED lighting panels as well. LGD will unveil the first OLED lighting speakers at the Light and Building tradeshow next week in Germany. You can see a couple of such lighting speaker designs above.

ETRI develops a flexible OLED with transparent graphene electrodes

Researchers from Korea's ETRI (Electronics and Telecommunications Research Institute) developed a flexible OLED panel that use a transparent graphene electrode. ETRI will detail this new graphene-based OLED panel at SID DisplayWeek 2018 in May.

The researchers produced a "fully operational" 40x40 mm OLED panel that uses the pixelated graphene film as electrodes.

The OLED Handbook, 2018 edition

We are happy to announce the eighth edition of The OLED Handbook, the most comprehensive resource on OLED technology, industry and market - now updated for 2018. The OLED industry grows and changes very fast, and the new edition include new details on the OLED mobile display market, new production fabs in China, OLED TVs, flexible OLEDs and more.

Reading this book, you'll learn all about:

  • OLED technology and materials and production processes
  • How OLEDs compare to LCD displays
  • OLED TVs, flexible OLEDs and transparent OLEDs
  • The OLED lighting industry
  • The future of OLED displays and lighting and the challenges ahead

The book also provides:

  • A history of OLED development
  • A guide to OLED investment
  • A comprehensive list of OLED companies
  • A list of existing and planned AMOLED fabs
  • OLED lighting roadmaps
  • An in-depth look into flexible OLEDs and OLED encapsulation

The OLED handbook has been read by hundreds of display engineers, business developers, researchers, equipment vendors, OLED material companies, private investors and others who wished to learn more about OLEDs today and in the future. I truly believe that it is the best introduction to OLED displays and lighting!

SEL develops a new Host-Guest system that enables red phosphorescent emitters with 5.4X the lifetime

Researchers from Japan's Semiconductor Energy Laboratory (SEL) developed a novel Host-Guest system that drastically improves the lifetime of OLED emitters. The researchers report that using this system, a deep-red phosphorescent emitter achieved 5.4 times longer the lifetime compared to the same emitter with a conventional system.

The researchers will present the new system at SID DisplayWeek 2018 in May. The new system is not only highly durable, it also satisfies the red chromaticity of the BT.2020 standard.
