Ignis demonstrates their MaxLife external compensation technology

Back in June 2012 I reported from SID on Ignis' Max Life technology. Max Life provides external compensation - that deals with OLED burn-in. The idea is to keep track of how much each pixel was used, and so it's possible to calculate the brightness loss in that particular pixel, and then drive this particular pixel correctly - to compensate. Ignis now released a nice video showing a 20" AMOLED panel (their own a-Si prototypes made by RiTDisplay) with a burn-in logo. When Max Life is turned on, the logo disappears:

Ignis explains that while Max Life theoretically makes the "eventual" lifetime (until the display burns out completely) worse, in practice it helps to make the device usable longer. Ignis says that the main problem is non-uniformity in brightness and not actual brightness.

China's Oasis New Energy embarks on a $500 million OLED project?

There's a report that CECEP Oasis New Energy signed an agreement with China's Suizhou district's government to build a new OLED fab with an annual capacity of 500,000 square meters. Total investment will be $500 million, and the company expects to reach an annual revenue of about $700 million.

We don't have any technical details about this new project, besides that the OLED panels will be use an a-Si backplane. Oasis NE is a solar PV developer and producer, based in Beijing, China.

The FDC shows two flexible OLED panels at SID

Just before SID, the Flexible Display Center (FDC) at Arizona State University (ASU) announced that they managed to fabricate the world's largest (7.4") flexible (bendable) OLED using Mixed-Oxide TFTs. Those MO-TFTs deliver high performance (fast switching speeds and reduced power consumption), are quite cost-effective and can be produced on existing a-Si production lines. The FDC demonstrated this panel at SID.

This OLED panel was developed with funding from the US Army features 480x360 (81 ppi) resolution, has an Oxide-TFT (IGZO) backplane and is built on a PEN (polyethylene naphthalate) substrate. It was developed in collaboration with Universal Display, DuPont (Teijin film), Sunic and Henkel.

Ignis Innovation at SID 2012

As I already said before, Ignis Innovation's SID booth was one of the conference highlights for me. Their technology is very impressive and hopefully will enable cheaper non-LTPS AMOLED production.

In their booth, Ignis were showing 3.5" and 20" AMOLED panels that use the company's a-Si backplane compensation technology. The panels were made by RiTdisplay. Ignis and RiTdisplay have been showing these displays back in 2011. Originally they were supposed to be released towards the end of 2011, but this never happened. During SID Ignis announced that now the plan is to release these by the end of 2012. According to Ignis the 3.5" AMOLED will be cheaper than the LTPS-based competition (i.e. Samsung made panels). You can read more about these panels and RiTdisplay's plans at my RiTdisplay-at-SID-2012 post.

RiTdisplay at SID 2012

RiTdisplay is a PMOLED producer based in Taiwan that has several production lines making PMOLED panels. A few years ago it was considered the world's largest PMOLED maker, although I now hear that due to financial problems the company shut down some of their PMOLED lines (this isn't confirmed though).

At SID 2012, RiTdisplay showed several PMOLED panels, and some 3.5" AMOLED panels. RiTdisplay is Ignis' production partner for its a-Si compensation technology, which basically enables a-Si to be used as a backplane for AMOLED panels (instead of LTPS or Oxide-TFT). This should enable cheaper AMOLEDs. You can read more about this technology at my Ignis-at-SID post.

First impressions from SID 2012

Update: Here's the complete list of OLED related posts and notes from SID 2012

So, SID 2012 is now over. Personally it was a very good show, even though I hear from many exhibitors that it was slow compared to past years. There were a lot of companies showing OLED displays, lighting panels and related products, and it seems that OLEDs are starting to become mainstream. I do plan to post in-depth posts with interesting details of my talks with various OLED companies, but in the meantime, here's my own "best of SID" list.

The FDC manufactured the world's largest Mixed-Oxide TFTs based flexible OLED (7.4")

Update: more information on this panel from SID 2012 here

The Flexible Display Center (FDC) at Arizona State University (ASU) have manufactured the world's largest (7.4") flexible (bendable) OLED using advanced Mixed-Oxide TFTs. The panel was developed in collaboration with the US Army Research Labs.

The FDC says that Mixed-Oxide TFTs deliver high performance (fast switching speeds and reduced power consumption) and are quite cost-effective and can be produced on existing amorphous silicon production lines.

Aneeve fabricate a fully ink-jet printed CNT circuit that drives OLED displays

Aneeve Nanotechnologies, a startup company at UCLA's on-campus technology incubator, managed to fabricate a new fully ink-jet printed carbon nanotube (CNT) circuit that is used to drive OLED displays. The company says that this is the first practical demonstration of carbon nanotube–based printed circuits for display backplane applications, and it shows significant performance advantages over traditional organic-based printed electronics.

Aneeve says that this shows that CNT is a viable technology to compete with a-Si and metal-oxide semiconductor for low-cost and scalable backplanes.

Hitachi unveils an a-Si based 4.5" IPS LCD with 329ppi

Hitachi unveiled a new 4.5" a-Si based IPS LCD display with 329ppi (720x1280). The company says that using amorphous silicon instead of an LTPS backplane means that the new display is cheaper then their previous IPS displays - with only a slight drop in performance (a lower contrast ratio).

Last month we heard that Hitachi, Sony and Toshiba signed an agreement to merge their small/medium display business. The new business venture will invest in OLED R&D and according to the companies, they consider OLED to be the core technology for next-gen small/medium displays. We do not know if Hitachi's new technology is relevant for OLEDs as well.

HP develops a new technology for producing large flexible OLED panels cheaply

HP has developed a new method to produce large AMOLED panels, based on roll-to-roll manufacturing. They say that one of the biggest challenges to make flexible OLEDs is the alignment on large area flexible substrates. The new solution uses self-aligned imprint lithography (SAIL) to laminate a well-defined micro OLED (µOLED) frontplane unto a flexible active matrix amorphous silicon TFT backplane.

HP says they already built a proof-of-concept AMOLED device - which contains a flexible µOLED frontplane with OLED sizes of 50 µm on PET and active matrix backplane on polyimide with pixel pitches of 1 mm. The company claims that the new method will enable large area OLEDs at a very low cost.
