LG leads in OLED TVs?

LG 77EC9800 OLED TV prototype CES Aftermath: is LG taking the lead in OLED TVs? LG sees a rapid push into OLEDs, while Samsung is less optimistic...

Hands on with the G Flex

Konica Minolta OLED mass production

Konica Minolta flexible OLED panel Konica Minolta is building a mass production roll-to-roll fab that will make a million color-tunable flexible OLED panels a month.
Recent OLED news:

Samsung Display (SDC) starts ordering equipment for the Gen-6 A3 AMOLED line

OLEDNet posted an article stating that major equipment companies in Korea reported orders from SDC. The manufacturing process equipment suggest that SDC is finally moving forward with its Gen-6 (1850x1500) AMOLED fab.

According to the report, SDC plans to complete the orders soon and wants to get it all by December 2014 and start mass producing in Q1 2015. The only major equipment orders left are for the encapsulation equipment. These may go to Veeco for their FAST-ALD systems, but we know that SDC is also looking at alternative approaches.

LG's 18" flexible and transparent OLED panels on video

Two weeks ago LG announced it has developed 18" rollable OLEDs and 18" transparent OLEDs, showing photos of two prototypes. LG now quietly released videos showing those amazing new displays, the largest ever flexible and transparent OLEDs.

The flexible OLED has of 1200x810 (80 PPI), and a curvature radius of 30R. As you can see it really can be rolled up (to a radius of 3 cm). We don't have a lot of technical details on the transparent panel, besides the fact that its transmittance is 30%.

A new OLED-Info report: The Flexible OLED Market Report

I'm happy to announce our third OLED market report, the Flexible OLED Market Report. This report provides a great introduction to flexible OLED panels, both display and lighting ones. It covers everything you need to know about flexible panels technologies. This is a great guide for anyone interested in flexible panels for their own devices, and also for technology and system suppliers.

Reading this report, you'll learn all about:

  • The different kinds of flexible OLEDs
  • What are the main challenges towards flexible OLEDs
  • All flexible OLED displays currently on the market
  • The emerging flexible OLED lighting market

The report package also provides:

  • Flexible OLED display product concepts and prototypes
  • An overview of the OLED display market
  • A guide into buying flexible OLEDs today
  • OLED luminaire concepts
  • Free updates for a year

Taiwan forms an OLED lighting commercialization alliance

The OLED Lighting Commercialization Alliance (OLCA) was formed a few days ago in Taiwan, with an aim to make Taiwan an important OLED lighting player. The alliance will promote OLED technologies and will include members from materials suppliers to product makers.

The OLCA seems to be led by Taiwan's ITRI. Other members include Merck, RiT Display, WiseChip, Corning, Tongtai Machine & Tool and the TLFEA (Taiwan Lighting Fixture Export Association). ITRI says that more than 60 companies have shown interest in collaborating with OLCA members.

Researchers from the University of Michigan developed metal-free phosphorescent OLED emitters

Researchers from the University of Michigan developed metal-free phosphorescent OLED emitters. The idea is that if the emitter molecules cannot vibrate, they cannot release energy and light and so more energy is converted into light. At first they tried creating a stiff lattice (crystalize the emitters) - this achieved 55% light conversion (better than the 25% of regular fluorescent OLEDs, but not as good as the 100% achieved by heavy metal doping).

But this method cannot be adopted for commercial OLEDs easily, and so the second method they tried is to tweaking the organic molecules so that they form structural bonds with a transparent polymer (they attach "like magnets"). This is an easier process, but it achieved only 24% efficiency - similar to a regular fluorescent OLEDs. But they are working on ways to improve this. The important point is that they demonstrated that increasing the intermolecular bonding strength could efficiently suppress the vibrational loss of the phosphorescent light.

eMagin to double OLED microdisplay brightness in new R&D projects

eMagin says that they will receive a number of R&D contracts over the next 2 months. The company will share more information when the contracts are officially signed, but they did say that they expect to more than double the brightness of their already ultra-high-brightness (5,000 cd/m2) full-color OLED microdisplays.

These new contracts will significantly increase eMagin's R&D contrat revenue beginning in Q3 2014.

DisplaySearch: small-size AMOLED production cost to fall below LCDs within 2 years

DIsplaySearch says that manufacturing costs for small-sized AMOLEDs are currently about 10-20% higher than comparable LCDs. A 5" Full-HD AMOLED for example, costs 16% more than a comparable LCD one.

But improvement in production yields will lower the gap - and in fact DisplaySearch sees OLEDs becoming cheaper than LCDs within two years, when AMOLED production yields reach 90%. DisplaySearch also says sees OLED materials cost reductions, which will also reduce prices further.
