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.

CPT aims to produce IGZO OLEDs in a 6-Gen fab it is building in China

Aug 27, 2016

Taiwan-based Chunghwa Picture Tubes (CPT) is building a new 6-Gen fab in China, with an investment of about $1.85 billion. Digitimes reports that CPT plans to produce IGZO backplane OLED panels in its second phase.

The first phase production is scheduled to begin at around June 2017 (construction will be completed by the end of 2016 and equipment installation will begin in Jaunary 2017). The first phase will produce a-Si LCDs, with a monthly capacity of 30,000 substrates. Digitimes did not say when is the second phase planned, and what kind of capacity will be allocated to OLED displays.

Fraunhofer researchers find that flexible OLEDs are safe for light treatment

Aug 27, 2016

The Fraunhofer Institute is working on alternative light sources for photo therapy, and Flexible OLED technology is prime candidate because it is light weight, can be flexed and does not produce almost any heat (unlike LED-based lighting).

Before flexible OLEDs are actually used in such treatment, though, it is important to know if OLEDs carry any potential toxic risks. The Fraunhofer FEP performed an initial study on in vitro cell cultures afflicted by defined damage. The researchers used flexible 10x10 cm green OLEDs, and found that the OLEDs positively stimulated the damaged cells, as expected. The tests showed now cytotoxity in the material systems, including when the OLEDs were bent (this increases the chance of material leakage from the OLEDs).

LG Israel sees an increasing demand for OLED TVs

Aug 27, 2016

LG hosted an OLED TV event in Israel together with the Israeli HomeTheater.co.il site. During the event, LG's Israeli executive said that the company aims to increase the OLED market share in the 55" TV category to 17% in 2016 (in terms of revenues, not shipments). The market share in 2015 was only 1.4%.

LG Israel OLED TV market share forecast 2016

This is a very ambitious target indeed, but LG says that they already see more and more people buying OLED TVs in Israel, OLED TVs are displayed in retail stores all over in Israel and people are asking about OLEDs and are starting to become familiar with the new technology. The 55" FHD OLED TVs are no longer considered "hi-end" by LG's Israeli marketing team, which is an interesting comment. You can see the full video below (in Hebrew):

Here is Wisechip's new transparent PMOLED prototype

Aug 26, 2016

Last week Wisechip announced that it will demonstrate its new flexible and transparent PMOLED panels. Wisechip achieved a breakthrough in transparent OLED production, and mass production will begin by the end of 2016.

Above you can see Wisechip's new prototype. It is a round 1.07" PMOLED that features a resolution of 160x136. We do not have any more technical details, but Wisechip says it achieves "good transparency".

Will SEL's ExTEF device architecture finally enable an efficient blue OLED?

Aug 26, 2016

Researchers from Japan's Semiconductor Energy Laboratory (SEL) developed a new OLED device architecture that enables efficient, long-lasting and low-drive voltage OLEDs, at practical brightness levels.

ExTET process and energy states diagram

The researchers call the new device architecture exciplex-triplet energy transfer, or ExTEF. The image above shows the elementary process and its energy state diagram. To create the emissive layer of the ExTEF, the researcher took a film with an electron-transporting material (ETM) and a hole-transporting material (HTM) and doped it with a phosphorescent dopant. Direct recombination between the electrons at the LUMO level and the hole at the HUMO level forms a charge-transfer excited complex (exciplex) - and the phosphorescent emission occurs via energy transfer from the exciplex to the dopant.

Oppo to release an LCD variant of the R9 following SDC's tight AMOLED supply

Aug 25, 2016

Earlier this month we reported that Samsung Display cannot supply enough AMOLED displays to Chinese phone maker Oppo, as SDC's production capacity is fully booked, and Oppo is seeing higher demand than anticipated. In fact some reports say that Oppo is selling more phones in China than Apple.

Now Oppo confirms this shortage of AMOLED display panels for the R9, and the company's president announced that Oppo will release an LCD variant called R9km. The LCD in the R9km will be supplied by JDI. The Oppo R9 (also known as F1 Plus) has a large display (5.5" FHD, 401 PPI) and is now available for around $500 in the US, unlocked.

AUO's 3.8" 90Hz AMOLED for VR application now in production

Aug 25, 2016

Taiwan's AU Optronics is currently focused on VR, wearable and automotive applications for its AMOLED displays. The company recently announced it is developing 3.8" and 5.5" VR AMOLEDs, and today we learn that the 3.81" panel is now entering production.

The new panel features a resolution of 1080x1200 and a refresh rate of 90Hz. It is intended for VR HMD applications - which use two such displays, one for each eye (the Oculus Rift, for example, uses two 3.1" 1200x1080 90Hz AMOLEDs produced by SDC). More information on AUO's new panel can be found on the OLED Marketplace.
