CPI demonstrates bendable OTFT arrays suitable for AMOLED backplanes

The UK's' Centre for Process Innovation (CPI) developed new backplane fabrication processes to allow the bending of Organic Thin Film Transistors (OTFT) arrays to small radii (1 mm) without a significant reduction in device performance. In the video below you can see a bending test of the OTFT array produced on a 50-micron thick PEN film. Those arrays can be bent up to 10,000 times.

The CPI hopes that these new processes will eventually lead to the adoption of such organic backplanes in OLED displays, and they say that the OTFTs feature a charge mobility that is "suitable" for OLED driving (although it was only 2 cm2/Vs. They have since upgraded it to 4 cm2/Vs) and they managed to fabricate display pixel-sized OTFTs.

Samsung: OLED shipments down in Q4 2013, but the market will expand as OLEDs will be adopted in more products

Samsung LogoSamsung reported their financial results for Q4 2013. Operating profit was lower than expected at $7.8 billion (compared to $8.3 billion in Q4 2012). Regarding OLEDs, Samsung says that total OLED shipments were actually down during the quarter, even though "new product sales increased".

Samsung however is expecting the OLED market to grow, as they plan to start adopting OLEDs in more products - including mid-range smartphones, tablets and wearable devices. The company will also launch "upgraded" flexible OLED panels in 2014.

LG Display to expand flexible OLED production towards the end of 2014

During LG Display's quarterly conference call, the company's officials updated on the LGD's OLED program. They confirmed again that the current flexible OLED monthly capacity is 6,000 4.5-gen substrates each month, and said that they have plans to expand the capacity towards the end of 2014. It seems that they mean to double the capacity, but their plans aren't fixed yet.

Regarding their M2 8-Gen OLED TV fab, it is progressing as planned and they still expect to ramp up that line in the second half of 2014. The capacity will not reach the full 26,000 monthly substrates at first, they will ramp up in two stages. The full capacity will only be reached in 2015.

Philips launches a new OLED lighting panel for signage and emergency lighting applications

Philips launched a new OLED lighting panel, the Lumiblade SI210.105, aimed towards signage and emergency lighting applications. This panel is 210x105 mm in size and only 2.5 mm thin, and features a luminance of 800 cd/m2, a color temperature of 4,500K and a lifetime of over 5 years (presumable with continuous operation).

Philips tells us that they see a real market for OLED lighting in emergency lighting. In fact ETAP already launched the world's first OLED emergency lighting product, the K4, and indeed they use the SI210.105 panel. Philips are now offering the panel for other OEMs. The OLED itself is a white OLED, and the OEM inserts a thin film with the graphics on top.

Pixelligent and OLEDWorks awarded $150,000 to develop a new light extraction material for OLED lighting

OLEDWorks logoPixelligent Technologies has been awarded an SBIR Phase I grant by the US Department of Energy (DOE). The nine-month, $150,000 program will enable Pixelligent (in collaboration with OLEDWorks) to accelerate the development of its nanoadditives for use in OLED lighting.

The project is titled "Advanced Light Extraction Material for OLED Lighting", and its aim is to develop an internal light-extraction structure that will be fully compatible with OLED device manufacturing processes and operating conditions that can expedite the commercialization of white OLED lighting.

tesa launches barrier adhesive tapes for flexible OLED encapsulation bonding

Germany's tesa, one of the world's leading manufacturers of self-adhesive tapes, launched a new barrier adhesive tape for OLED encapsulation bonding, suitable for flexible panel production.

The new barrier adhesive tapes are transparent transfer barrier tapes that feature the company's DrySeal liner technology (which enables extreme drying of barrier adhesive). This realizes an immediate and direct encapsulation of OLED materials over the full surface without initial degradations caused by water-vapor.

Will LG be an exclusive supplier for Apple's iWatch's 1.52" OLED displays?

Back in December 2012, rumors started to circulate about an upcoming Apple smartwatch called the iWatch, that will use a small PMOLED. Later rumors suggested Apple decided to use a plastic flexible OLED, possibly from LG Display.

Today a Korean publication (Digital Daily) reported that LGD has indeed been selected as the exclusive supplier for Apple's iWatch. LGD will start producing 1.52" OLED panels in Q3 2014, with an initial production volume of 2 million panels per month. The iWatch itself will be released in Q4 2014. The story was later removed from the Korean site, which can mean anything.
