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:
Samsung Display (SDC) was established in 2012 as a merger a merger between Samsung Mobile Display and S-LCD. SDC is the world's largest display maker that produces both LCD and OLED panels for mobile devices and TVs. The company announced a couple of days ago that it integrated its OLED division with the LCD division.
SDC now wants to realize "organic integration" between OLED and LCD divisions. They also integreated their sales and marketing divisions in an effort to simplify display marketing. We know that SDC sees OLED as the leading future display technology (with a great emphasis on flexible displays) so this move may be yet another step towards SDC's transition to OLED technologies.
In August we heard a report from Japan that Taiwan's Hon Hai (Foxconn) is establishing an OLED R&D center in Japan (possibly in partnership with Sharp's Sakai Display Product) with an aim to start AMOLED panel production in 2015. Today Taiwan's OFWeek reports that Hon Hai is developing high resolution OLEDs aimed for mobile phone and tablets with plans to start volume production in 2015.
According to the report, Hon hai will first develop OLED panels with 350 PPI, and will supply them to Chinese mobile phone makers. Then the company will produce high-resolution panels (up to 450 PPI) as they hope to supply OLED panels to Apple.
Reports from Korea say that Samsung is talking about using an LCD display in the upcoming Galaxy S5 and Galaxy Note 4 mobile phones - mostly in an attempt to reduce costs. Samsung is facing competition from lower-cost Android phones and need to lower the cost of their phones.
Samsung started adopting AMOLED displays in their high-end mobile phones years ago, but whenever people start discussing the next one, there are always rumors that they will switch back to LCD. It happened with the Note 3 and with the GS4. As we know, both phones use Super AMOLED panels.
Samsung announced today that they shipped over 10 million Note 3 smartphones (or phablets, really). It took them a little over 2 months as the Note 3 was launched on September 25. Before they launched the phone, Samsung said that they shipped over 38 million Galaxy Note and Note 2 smartphones since launching the original Galaxy Note in 2011 and they quickly reached their target of 10 million Note 3 sales.
The Galaxy Note 3 has a 5.7" Full-HD Super AMOLED display (386 PPI). DisplayMate says that this is the best OLED display ever, and in fact it outperforms the best LCDs across the board. The Note 3 also has a 2.3 Quad-Core CPU (or a 1.9Ghz octa-core in some markets), 3 GB of RAM, 32/64GB of storage, a 13 MP camera (will be capable of 4K videos in some markets) and Android 4.3.
Reports from Korea suggest that LG Display and Merck are in talks to co-develop OLED ink jet printing materials. Merck is already supplying evaporable OLED materials to LG Display for their OLED TVs, and now they want to also supply soluble materials for LGD.
Merck is focused on OLED printing technologies over evaporation technologies as the technological advantages will enable cheaper large area panels. According to a Merck presentation released earlier this year, it seems that Merck wants to become an OLED solution provider, not just a material supplier as this will maximize the value for both Merck and its customers. The company currently has around 80 OLED R&D experts and around 1,400 related patents.
According to Korea's Naver portal, Samsung is developing two new tablets that sport AMOLED displays - an 8" one and a 10' one. One of them will be launched together with the Galaxy S5 (which may go into production as early as January 2014).
Samsung's AMOLED tablets will be high-end ones, aimed to grab market share from Apple's new iPad and iPad mini. Samsung will continue to use LCDs is low-cost and mid-range tablets. Until these new tablets are launched (if the story is correct), the only OLED tablet by Samsung was the the 2011 Galaxy Tab 7.7 with its 7.7" Super AMOLED Plus 1280x800 display.
Apple continues to file patents for new OLED technologies - a few days ago the USPTO unveiled a new patent that describes OLED displays with integrated thermal sensors. The idea is that OLED change their color and brightness as the temperature changes - they get dimmer when they are hot. This mostly effect red OLEDs. If you measure the heat of different areas in the screen (which may get warmer because they are close to a radio transmitter for example) you can compensate and get more accurate colors.
Apple's patent describes a system that integrates the sensors into the display itself, and these sensors can be used to check the temperature of different zones in the display - or even each individual pixel. A software controller is used to determine how much compensation is required for each OLED pixel.
