Recent OLED news:

The EPO upheld one of UDCs basic PHOLED patents (EP870)

The European Patent Office (EPO) ruled to upheld one of Universal Display's key PHOLED patents (EPO#EP1394870). This patent, which UDC refers to as EP870, details an OLED in which the emissive layer contains phosphorescent dopant compounds. This patent corresponds to the company's US'238 patent.

In November 2013, the Japanese High Court decided to validate UDC's claims in Japanese patent #4511024, which is a counterpart patent to the EP870 and US238 patents. Later in November, The EPO revoked one of UDC's basic phosphorescent OLED patents, EPO#1449238. The opposing parties included Sumitomo Chemical, Merck and BASF.

Researchers develop software that automatically rewrites web pages to consume less power on OLED displays

Researchers from the University of Southern California developed a new software platform that can automatically rewrite web pages and web applications so that they consume less energy on OLED pages (i.e. reduce average pixel brightness). They report that using the software can achieve a 40% reduction in display power consumption.

The software, called Nyx, changes the colors of the web pages (or application) by choosing a new and efficient color scheme. The clever part is that the software chooses colors that are more efficient but that still maintain the color relationships between neighboring HTML elements as before.

Two OLED related week-long summer schools scheduled for 2014 in Poland

The Polish Academy of Science is organizing two new OLED related summer schools in 2014. Those International Krutyn Summer Schools are high-level and highly intensive scientific events that include training in the form of lectures and scientific consulting sessions designed for PhD students and young researchers seeking to reinforce their knowledge and skills.

The first event (summer school #15) focuses on organic photonics and electronics, with profound emphasis on revolutionary TADF emitters as OLED materials replacing expensive platinum group metallacycles. The week long event (June 8 to June event is organized jointly by Japan's Kyushu University and Poland's Supramolecular Chemistry Network Foundation, and the Institute of Physical Chemistry of the Polish Academy of Sciences. More information can be found here.

Plastic Logic shows a 4" 360x128 fully-organic flexible OTFT AMOLED prototype

Back in February, Plastic Logic and Novaled (owned by Samsung) announced that throughout 2014 they will demonstrate truly flexible, plastic, full-organic AMOLED displays. The first demo in February was of a monochrome (red) display - and actually it was only shown on a presentation slide. But Plastic Logic promised us that they will show better prototypes as the year progresses.

True to their word, last week, at the Printed Electronics Europe event, plastic logic showed a full-color, 4" 360x128 (95 PPI) flexible AMOLED prototype. This time it was a real demo, as you can see from the photo above. This full-organic AMOLED panel uses Plastic Logic's flexible OTFT backplane and the whole panel can be bent and rolled and still show the image.

Samsung's Galaxy S5 is now shipping worldwide

Today Samsung is launching the Galaxy S5 worldwide. In the US, both AT&T and Sprint offer it for $189 (with a plan) or $699 unlocked. The GS5 features a 5.1" FHD (432 PPI, Diamond Pixel ) Super AMOLED display, a 2.5 Ghz quad-core CPU, 2GB of RAM, 16MP camera (4K video support). The GS5 is dust and water resistant, and it packs a finger scanner and a heart rate sensor.

The 5.1" Super AMOLED display was tested by DisplayMate, who found it to be the best mobile display on the market - outperforming all other OLED and LCD displays as it features the highest brightness, the lowest reflectance, the highest color accuracy, the highest contrast rating in ambient light and the smallest brightness variation with viewing angle.

Q&A with Universal Display's Director of communications

Universal Display Corporation (UDC) is one of the most known OLED company, involved with OLED IP, OLED phopshorescent materials, innovations on flexible OLEDs, production processes and more. As the most prominent public OLED company, the company is interesting to many investors and analysts.

Last year UDC hired Darice Liu to handle communications and investor relations. Darice was kind enough to answer a few questions I had regarding UDC's technology and business. These are interesting times for UDC as the OLED market is growing quickly, OLED TVs and flexible OLEDs are finally appearing on the market, but on the other hand the company is being faced with patent litigation and criticism from some investors (whom I shall not name).

BMW expects OLED lighting in commercial cars within 3 years

BMW hosted a workshop called "Light Days" which detailed the history, present and future of lighting in automobiles. BMW says that the future lighting technology will be OLED, and they expect to start selling cars with OLED lighting within 3 years.

BMW says that the high homogeneity of OLEDs has several advantages (as you can see in the slide above) - mainly that it enables new styling options, it's efficient and long lasting and can offer high exclusivity. The company showed a prototype taillight design that uses Philips OLEDs. We also know that LG Chem are collaborating with BMW. This design seems pretty similar to Hella's own OLED prototype (which uses LG Chem's panels).
