DisplayMate: the OLED displays in Samsung's new tablets are the best tablet displays ever tested

DisplayMate posted yet another interesting display shoot-out, this one testing Samsung's new QHD (2560x1600) Super AMOLED displays used in the upcoming Galaxy Tab S (8.4 and 10.5) tablets. As these displays are very similar to the GS5 display, it's not surprising that DisplayMate found those tablets to offer the best performing displays ever. This is yet another testimony to how great OLED displays are - and the rate of improvement in OLEDs is very rapid.

As DisplayMate found out, the Galaxy Tab S establishes new records for best Tablet display performance in: Highest Color Accuracy, Infinite Contrast Ratio, Lowest Screen Reflectance, and smallest Brightness Variation with Viewing Angle. These are also the highest resolution tablets at QHD.

BOE produces sample 55" 4K OLED TV panels at their Gen-8 pilot line in Hefei

A couple of weeks ago I reported that BOE showed a 55" 4K WRGB OLED TV at SID 2014. When I posted on this, I said that BOE probably used a panel supplied by LG Display (although it didn't make a lot of sense).

BOE 55-inch OLED TV prototype

It turns out that I was wrong, and that panel was produced by BOE Display themselves, at the company's AMOLED pilot Gen-8.5 line in Hefei. The panel uses a bottom-emission white OLED with a color filter array (WRGB architecture). BOE also uses internal compensation technology. The 5 mm thick panel features a contrast ratio of over 100,000:1, a response time of 0.2 ms and a brightness of 120-400 nits.

NeoView Kolon is developing flexible transparent OLED panels

Korea's NeoView Kolon has been developing OLED panels for a long time, and while we knew the company is already producing transparent panels, it was a nice surprise to learn that the company is also developing flexible panels. In fact, in this nice video that was sent to us, you can see a prototype flexible transparent OLED:

The video also shows some older transparent OLED prototypes for the automotive market that the company developed for Kia, and the company's TOvi transparent OLED-based HUD that is already shipping in the Korean market.

LG ships their OLED TV in impressive glueless packaging

It seems that LG is so proud of its OLED TVs (justifiably so, really) that it uses a unique packaging. It is highly recyclable, as it is all made from cardboard without any glue, and it uses a modular design that you can easily take apart and fold.

I don't know whether LG uses this packaging for all their OLED TVs, or for just one model. Currently the company offers 3 different 55" models - the curved 55EA9800, the flat 55EM9700 and the flat 55EA8800 (GALLERY TV).

A pyramid-shaped OLED structure is brighter than a flat panel

Researchers from the University of Michigan, trying to make OLED brighter but still efficient, discovered that a pyramid-shaped OLED lamp is more efficient than a flat panel shape. The idea is that the reflective OLEDs are emitting in the inside of the pyramid, and all the light comes out of the open base.

The surface emitting light on the inside is more than four times larger than the opening at the base of the pyramid, but the whole pyramid consumes about three times less electricity than trying to achieve the same brightness with a flat panel the size of the base. In addition, the researchers found out that this device achieves a better light distribution (the "halo" effect).

The OLED Handbook - over a 1,000 copies sold!

In May 2011, I launched The OLED Handbook, my comprehensive guide to OLED technology, industry and market. The book is now in its fourth edition, and I'm quite proud to say that over a 1,000 copies have been sold in three years! And this does not include site/enterprise licenses and upgrades.

So yes - I'm bragging a little bit, but it's also great to see more and more people and companies from all over the world that want learn more about OLEDs as the technology gets more and more prevalent. And of course this provides great social-proof. If you haven't yet bought and read the OLED Handbook, please consider doing it today...

Mitsubishi, Okamura and Taisei developed an OLED desk lamp for office use

Mitsubishi Heavy Industries, in collaboration with Okamura and Taisei, developed an OLED desk lamp for offices. Taisei is constructing a Net-Zero Energy Building (ZEB) in Yokohama, and the OLED lamps will be installed in this building for testing.

The Japanese government has called for new public buildings to be ZEB-compliant by 2020. Lighting takes up about 20% of the electricity in offices so it is a key target for energy saving efforts.

Nanomarkets: the OLED material market to reach $3.7 billion in 2019

Nanomarkets released a new OLED materials market report, in which they forecast that the OLED material market will grow from $900 million in 2014 to $3.7 billion in 2019. Almost 45% of material revenues will come from the core functional materials (the OLED stack, as we call it: EML, ETL, HTL/EBL and HIL). The rest of the materials are electrode, encapsulation and substrate materials.

According to Nanomarkets, OLED TV future is still uncertain, especially since Samsung is "having second thoughts about this business" (I don't really agree with them on that). Nanomarkets still expects strong OLED display growth on from smartphones, tablets and wearables. Solution processing is making good progress, and Nanomarkets expects the soluble material market to grow from $40 million in 2014 to $335 million in 2019.

Apple, looking for another flexible OLED iWatch supplier, to end patent war with Samsung?

There's an interesting report from Korea that suggests that Apple and Samsung are showing "signs of a ceasefire" in their long-running patent fight. According to the report, Apple wants to keep Samsung as its component supplier.

Samsung Display is a key Apple supplier. SDC makes 9.7" LCD panels for Apple's iPads, and they shipped over 5 million such panels in Q1 2014 alone (Apple is on of SDC's top three clients, responsible for 9% of SDC's sales).
