OLED-Info is the web's leading resource on OLED TVs, displays and lighting.
OLED (or AMOLED) screens are efficient, clean, thin and bright, and are becoming popular in mobile devices. We bring you daily news and resources on this exciting new technology!
Recent OLED news:
Audi unveiled a new concept two-door car, the Prologue, which marks a new design language for Audi, which will adopted in the German automaker next-generation cars. The Prologue uses a full-width OLED (made from three panels) dashboard instrument display, and another bendable OLED mounted at the case of the centre console:
Audi says that the bendable OLED is one of only 10 in existence. Audi did not disclose the display maker, but it can be either Samsung Display or LG Display. In July 2014 LGD announced that it signed supply contracts with several German car makers to supply OLED displays - including flexible OLEDs so it makes sense this panel is indeed made by LGD.
MRAM developer Crocus Technology developed a new MRAM-based magnetic sensor that can be used to detect the shape and bendability of flexible displays. The idea is that you place a sensor every 5 cm or so (depending on the display size and bending radius) and this allows you to determine whether the display is bent and in which way.
A flexible sensor such as this can be used to correct the image that gets deformed when bent. It can also be used potentially for UI purposes - similar to Nokia's Kinetic prototype phone shown in 2011.
Quantum Dots enhanced LCDs are starting to enter the market, with reports saying that both LG and Samsung will release such TVs in 2015. Michael Grund, the managing director of Merck Korea, however, says that this technology will not have a significant impact on the global TV and display markets - unlike OLED which could be a game changer.
Quantum Dots are used to enhance the color gamut and efficiency of LCD displays. Sony already commercialized quantum-dots TVs and smaller panel display, as the QD-LCDs are far easier to produce compared to OLED TVs.
Samsung hosted an investors forum in NY a few days ago, and it is reported that much of Samsung's focus was on OLED technologies. As we already reported, Samsung Electronics announced that flexible OLED is one of its 3 areas of future growth (especially as they struggle to increase high-end mobile phone sales), and during the conference the company revealed some interesting information and prototypes.
So first up were two new foldable OLED prototypes - a 5.5" (WQXGA, 2048x1526, 464 PPI) panel that folds in half and a 10" tri-foldable AMOLED (Full-HD, 218 PPI).
One year ago, OLED-Info, in collaboration with Global IP News, launched a new service: a daily newsletter covering OLED patents news. The OLED patent Newsletter provides valuable daily patent information from more than 85 countries. In the past year, the newsletter enabled many OLED companies and research institutes to track the OLED patent scene and protect their IP.

DisplayMate: Samsung's Galaxy Note 4 offers the most accurate color reproduction of all mobile displays
DisplayMate published a new article focusing on display color accuracy. Testing the six leading mobile displays, DisplayMate tested which ones perform best in terms of color accuracy. While all displays performed very good, DisplayMate found the Galaxy Note 4 to be the winner in this test, achieving the best results in all tested categories.
Historically, people often complained that Samsung's OLED offer overly saturated colors and inaccurate images. It's great to see OLEDs overcome yet another perceived disadvantage and yet again prove that even at its infancy, OLEDs outperform LCDs in yet another aspect.
Several new reports today suggests that Samsung is accelerating its OLED development. First up is Samsung Electronics, which announced that flexible OLEDs is one of three businesses areas it will focus on for future growth (the other two businesses are fin-FET semiconductors and startup incubating).
Samsung Display, meanwhile, updated that they aim to launch a foldable OLED panel (that can be folded in half) by the end of 2015. This is not really news as it was stated back in 2013, but it's still good to hear they still aim to produce foldable displays next year. SDC also hints at a possible multi-edged smartphone that will succeed the Note Edge which uses a one-sided curved OLED.
