Philips to reach OLED lighting panel efficiency of 120 lm/W by 2019
Jan 24th
Digitimes Research posted about Philips lighting unit, and they said that the company’s goal is to reach an efficiency of 120 lm/W for their OLED lighting panels by 2019. We talked to Philips and indeed they confirm this number. Philips is gearing up to start production in their new Aachen production plant which will increase production capacity tenfold and will also lower prices considerably. This is quite an increase from the panels Philips make today. The regular Lumiblades offer around 12 lm/W, while the Lumiblade Plus (a phosphorescent panel, developed by Konica Minolta and produced by Philips) offers 45 lm/W. We reviewed Philips’ new Lumiblades recently , here’s the short hands on video: read more

LG Display announces their 55" OLED TV prototype, to be unveiled at CES
Dec 26th
LG Display announced that they will unveil a new 55″ OLED TV panel at CES 2012 , and offered some more details and a couple of photos. Last month LG said that their OLED TVs will be available in the middle of 2012 . The panel is only 5mm thick, and is also lighter than LCD panels. It features a 100,000:1 contrast ratio, fast refresh rates and a wide color gamut (wider than LCD, according to LG). They also say that the TV is more power efficient than an LCD TV, but they wouldn’t give any details yet. LG Display’s panel uses an Oxide-TFT backplane (this was announced before ). According to LG this backplane offers an identical image to LTPS panels, while being significantly cheaper. The TV uses a white-OLED with color filter design (this was the technology LGD acquired from Kodak back in 2009 ). read more

New white top-emitting OLED architecture achieves high efficiency and outstanding color quality
Dec 24th
Researchers from Dresden’s University of Technology (TU Dresden) developed new highly efficient white top-emitting OLED design that feature “outstanding” color quality, and is compatible with flexible OLEDs. In this new design a refractive index matched microlens film was laminated to the top-emitting OLED to form direct optical contact. This enabled the researchers to achieve a CRI of 93, CIE coordinates of (0.472, 0.430) and an emission from 410 to 750 nm that almost spans the complete visible spectrum (380 to 780 nm). The efficiency is up to 30 lm/W (on par with the latest record white OLEDs from Novaled and OSRAM ). The lamination of such an outcoupling structure should be fully roll-to-roll compatible and even allows to be used as an encapsulation film when water and oxygen barriers are added. read more

Panasonic announces OLED lighting roadmap, to start selling panels tomorrow
Aug 31st
Panasonic Electric Works (PEW) released some very interesting news today regarding their OLED Lighting project. First of all, they announced that ; Panasonic Idemitsu OLED Lighting (PIOL), their joint-venture with Idemitsu Kosan will start shipping OLED lighting panels tomorrow (September 1st) – to local and international markets. Those rather small (80x80mm), thin (2mm) and light (38g) OLED panels will feature no less than Ra90 color rendering (they say it’s the world’s highest) and 3,000 cd/m 2 – the world’s brightens panels. The efficiency is 30 lm/W and lifetime (D70) is 10,000. The temperature is 3,000K (like a regular light bulb). PEW itself will start offering OLED lighting modules in December 2011 – which will include the OLED panel, a frame and a built-in control circuit. PEW says that these modules will be “easy-to-embed” and will have a narrow frame design (11mm maximum width). You will also be able to replace the OLED panel in the modules in a simple way. read more

Super AMOLED HD is real, Samsung developed an improved process and uses new materials
Aug 17th
I just had an interesting talk with two industry insiders (one of them is a Samsung supplier) – about Samsung’s upcoming Super AMOLED HD display . It turns out that these displays are indeed real – and will be unveiled soon. We can expect 5″ to 6″ smartphones in fall 2011 (the first will probably be the GT-I9220 with a 5.3″ display ) and 7″ tablets by the end of 2011. A 7-inch Super AMOLED prototype According to my sources, Samsung managed to achieve HD resolution on these small displays by using PenTile matrix again (like in the original Super AMOLED displays). They have also developed a new manufacturing process and are using new materials. It might be that they have finally started to use Universal Display ‘s green PHOLED (we reported that Samsung is using a green phosphorescent in their new 5.5-Gen plant , but perhaps they will only start using it in the HD displays). read more

Samsung shows a 46" transparent LCD powered from a small solar panel at ambient light
Mar 8th
Samsung is showing a new 46″ transparent LCD display that is so efficient it can run from a small solar panel at ambient light. The panel supports Full-HD resolution (1080p) and offers ten-finger multitouch surface. Samsung plans to commercialize this technology ‘soon’: read more

Super AMOLED Plus resolution explained
Feb 14th
Earlier today we posted about the Super AMOLED plus resolution – and now we got our answer. It turns out that my calculations about the pentile matrix were incorrect – it fact it uses 2 sub-pixels for each pixel while a ‘real’ RGB matrix (or Real-Stripe as Samsung calls it) uses 3 sub-pixels for each pixels – and here’s your 50% increase. Here’s Samsung’s own image showing the difference: It also turns out that a Real-Stripe matrix also takes up more space per pixel. This explains why a 4.3″ display that uses Real-Stripe has the same resolution as a 4″ with a penTile matrix. But this display should actually be clearer because of the added sub-pixels and better matrix design. read more

Spintronics breakthrough could lead to lighter and more efficient OLED displays
Dec 8th
Researchers from the UK and Switzerland have shown that a magnetically polarized current can be manipulated by electric fields. This is the first time that it was shown how you can proactively control spin with electric fields and could pave the way towards combining memory and processing power on the same chip. The interesting part is that this discovery has been made with flexible organic semiconductors, and so could offer a step-change in the power efficiency and weight of devices based on such materials, including of course OLED displays. read more

STMicroelectronics unveils new AMOLED power chip that increases battery life
Sep 24th
STMicroelectronics has unveiled their latest power management chip aimed for AMOLED (and Super-AMOLED) display – the STOD03A. The new chip has an improved performance (compared to the STOD02). ST says that only six external components are needed to complete the power-supply circuitry, making the STOD03A the most attractive for handset builders. The STOD03A uses highly efficient synchronous operation for both voltage outputs, achieving up to 85% overall efficiency for longer overall battery life. Other power-saving features include automatic pulse-skipping operation for low power consumption at light loads, and a true shutdown mode drawing less than one microamp activated through the enable pin (EN). ST has achieved its high performance using its Silicon-On-Insulator (SOI) technology as part of its latest-generation BCD fabrication process, which enables analog, digital and closely spaced high-power circuitry to be built on the same chip. read more
