OLED-Info: The OLED Experts
OLED-Info has been the leading international OLED publication for over 10 years, with a readership of more than 100,000 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.
Recent OLED news:
The MX5 is Meizu's flagship smartphone for 2015. It features a 5.5" Full-HD (401 PPI) Super AMOLED display, an Octa-Core CPU, 3GB of RAM, 20.7mp main camera, dual-SIM and Android 5.0.
The MX5 will ship in early July in China for ¥1790 ($289) for the 16GB model.
According to my sources, OLED Technologies & Solutions BV, an OLED display manufacturing solution provider, has filed for bankruptcy. This is a sad ending to a long standing OLED company that started out as OTB Display years ago.
OTS offered a total solution for OLED display manufacturing: in-line OLED printed display manufacturing systems, backplane and display product development, OLED device, stack, and ink development, process development expertise and display characterization and improvement. The company developed a fully automated printed OLED processing line, the PCAP-20, and was developing their next-gen tool, the PCAP-48, a Gen-4.5 OLED processing line, designed to produce high quality large screen HDTV displays with industry record yields and lowest cost per display.
Reports from Korea suggest that Apple is considering to use an OLED display in the 2018 iPhone. The main reason that is quoted is that Apple wants to improve the saturation and brightness of their mobile phone displays.
According to the reports, LG Display may be chosen as the main OLED supplier. LG Display's current small-sized OLED capacity is very small, and so the company will convert its LCD facilities in Gumi to produce OLED displays, with mass production reached by the end of 2017.
Researchers from Korea's Ulsan Institute of Technology announced that they have developed a new technique that can improve the efficiency of Iridium-doped phosphorescent emitters by more than 30 times.
The team explained that this dramatic increase in efficiency was achieved by a new method to synthesize molecules - which resulted in "stronger" molecules. More precisely, the researchers created an emitter molecule in which the two carborane units were thethered by an alkylene linker.
Anandtech posted an interesting article discussing the power consumption of Samsung's AMOLED displays, from the GS4 to the GS6. The basic results are show in the graph below, which compares the power consumption of a completely white screen at different brightness levels:
You can see that The GS4 is by far the worst performing screen of the bunch. Samsung is consistently improving its AMOLED displays, but from the GS5 onwards it also introduced PSR (Panel Self Refresh) functionality which helps reduce power consumption on static images.
LG Electronics announced that it is going to cooperate with Google in promoting its OLED TVs. LG will use YouTube and other Google tools to help increase OLED TV awareness, targeting the global high-end consumer market (estimated at around 100 million).
LGD aims to produce 600,000 OLED TVs in 2015 and 1.5 million in 2016. Some reports say that LG's OLED sales are lower than expected - which may explain why LG is attempting a global marketing push. LGE recently reduced $1,000 from its 2015-model UHD 55" curved OLED TV, but OLED prices are still considerably higher than competing LCD models.

To further improve the efficiency and life-time of organic light-emitting diodes (OLEDs), ultimately the properties of underlying materials need to be tweaked at the molecular level. In materials science, as in other fields, modeling has become a more wide-spread tool integrated with experiments for a holistic research & development approach.
In particular, high-throughput screening computational screening may considerably reduce experimental costs for synthesizing and testing new materials. At the molecular level there are a few properties that are important for OLED life-time and efficiency. A simplified set up for an OLED device is depicted in Figure 1. The charge mobility and light emission properties can be predicted with computational chemistry, as explained below.
