Samsung developed touch transparent AMOLEDs
Sep 9th
Samsung has developed a touch-enabled transparent AMOLEDs, and has a very nice demo showing it off. Sadly we do not have any technical details about this display, or when Samsung expects to commercialize it… Back in February, we learned that Samsung is strongly into transparent AMOLEDs , and want to introduce several new products that use this technology. Here’s another great use of transparent OLEDs in a wine point-of-sale or museum or information center.

Samsung plans to release plastic-based AMOLEDs by 2012
Jul 20th
Samsung plans to launch new AMOLEDs on a plastic substrate within two years. They say that these new AMOLEDs will be ‘unbreakable’. They will also be lighter, safer and thinner. These qualities can be useful in mobile phone displays, which will allow Samsung to keep their AMOLED price premium in these years. Samsung plans to place a TFT on the plastic panel and to replace the existing vinyl protection sheet with PI (polyimide) film to avoid residue upon light emission. Samsung revealed flexible, unbreakable AMOLED prototypes back in 2009, see video above.

GE and KM: efficiency breakthrough (56 lm/w) in roll-to-roll printable white OLEDs
Jul 16th
GE and Konica Minolta announced that they have achieved a “major breakthrough” in their white OLEDs: an efficient 56Lm/w flexible white OLED that is made using solution-coatable materials in a roll-to-roll printing process. The materials have “commercially viable lifetime” (we do not know exactly what they mean by that). GE and Konica Minolta flexible desk lamp prototype GE and Konica Minolta plan to introduce their flexible OLED lighting products next year (2011), and have already displayed some early prototype lamps (one of which is shown above). They are working together since 2007 . KM hopes to see $1 billion in OLED Lighting sales by 2018 . KM has licensed OLED IP from UDC .

Novaled to remain in the IP & Material business, OLED displays
Jul 13th
Last week we reported that Novaled is set to become an OLED Lighting manufacturer , moving away from the display business (the original post came from OLEDNet). Today Novaled tells us that in fact this is not true. Novaled’s core business remains their technology licensing and material sales (the materials are made by BASF). They are also acting very successfully in the display field and have very good relationships with Korean manufacturers. So this sets things straight…

Samsung to soon double their AMOLED’s efficiency, lifetime and power consumption
Jul 2nd
Samsung is aiming to improve their AMOLEDs in the near future. They claim they will double the efficiency (from 20cd/A to 40cd/A), the lifetime (from 50,000 to 100,000 hours) and the power consumption (from 62W to less than 30W). Samsung will use advanced color pattern methods to overcome the current FMM method large-size limitation. They will also move from glass encapsulation to thin-film, and apply Oxide substrate. They will also use only triplet OLED emitters instead of using both singlets and triplets. Samsung has recently began to construct their new 5.5-Gen AMOLED plant , which will start production in July 2011. Samsung plans to invest $2.2 billion on that plant that will have 3 production lines (1300X1500mm). Having a larger wafer size results in better efficiencies for both small and large panels (such as 30″ or 40″ OLED TV panels).

Russian physicists use Nanocrysal to make long-life OLEDs
Jun 26th
Russian physicists has found a new way to make a long-living OLED. They are using nano-crystals of cadmium chalcogenides instead of the organic Chromophores in the OLEDs. Those Nanocrystals are long-lasting and when their size change, luminescence wavelength also changes, so it is easy to get required emission wavelength. They physicists say that the manufacturing process of the new devices is very similar to regular OLEDs, there’s only one change in the process, when colloid solution of semiconductor nano-crystals is mixed with organic semiconductor. read more

Microsoft uses a transparent OLED with a camera underneath for gesture control
Jun 24th
Transparent OLEDs are exciting (and Samsung wants to tap that market ) – but a lot of people wonder what is it really good for? Microsoft is showing a nice concept: using a camera beneath a transparent OLED to create gesture-based UI. The camera “sees-through” the OLED: Microsoft are using a Samsung-made transparent AMOLED panel.

E2M introduces new OLED lighting kits based on Philips & OSRAM panels
Jun 16th
E2M Technology is introducing two OLED lighting kits based on OLED panels made by Philips and OSRAM. The first kit is called White Amethyst, and includes a 4cmx4cm Philips’ Lumiblade white square panel (like the one we reviewed a while back ). The kit includes one OLED panel, a driver and PC software (which can alter the lights luminosity level and program lighting sequences for up to four OLEDs via USB port). The kit also includes an on-board light sensor. It costs £459. Here’s a sample art-piece that E2M is showing, using the White Amethyst kit: The second kit is called White Sapphire, and this one is based around OSRAM’s ORBEOS panel ( here’s our review of the ORBEOS ). The ORBEOS is larger (a circle, 79mm diameter) than the Philips’ square panel. The kit is otherwise pretty much the same, with the same driver and software. It costs £609. read more

UDC awarded $99,000 to advance Phosphorescent OLED Lighting
Jun 16th
Universal Display announced that they have been awarded a new Small Business Innovation Research (SBIR) Phase I $99,900 program from the U.S. Department of Energy (DOE). During this program, the Company will study the potential to enhance the performance of white PHOLED lighting devices in order to meet DOE requirements for general illumination applications. Under a program titled “Thermal Management of High-Efficacy White Phosphorescent Organic Light Emitting Devices,” Universal Display will design and build white PHOLED lighting panels to evaluate the impact of operating temperature on performance. read more

Build your own linux tablet with a 4.4" OLED display
Jun 16th
Liquidware (an open-source electronics firm) has released a kit that can be used to make a linux tablet with a 4.4″ (480×272) OLED touch display. The kit includes a BeagelBoard Rev C4 board (with a 720Mhz ARM Cortex-A8 OMAP cCPU, 20mm speaker, SD slot (it comes with a 4GB card), Wi-Fi, mini USB port and a battery. So you won’t get a real tablet – it’s very thick, and not very pretty – but you can play videos and access the web. And it costs just $393. Here’s a short video on the kit: read more
