Samsung OLED TVs in Q4 2012, LG's in 2013?

Samsung Electronics president says that Samsung aims to start mass producing 55" OLED TV panels in the fourth quarter of 2012. This is in line with earlier estimates, even though at the beginning of the year Samsung hoped to begin mass production around June or July of 2012.

Samsung does plan to continue and lead the global TV market, and they see OLED technology enabling them to making a "second leap forward". Samsung's president further revealed that he sees transparent displays as the next emerging technology following OLED. Samsung thinks that ultra-definition is not going to be so important in the near future due to the lack of content.

Meanwhile, Digitimes says that LG Display is delaying their OLED TV production to 2013. The company originally intended to launch the OLED TVs in time for the Olympic games in London (August 2012) - but they failed to do so...

OLED legal battles

In early September, Samsung Display filed a lawsuit against LG Display over OLED technology tech leak. Samsung Display claims that LG Display stole 18 confidential technologies relating to OLED displays, demanding a billion won (almost $900,000) for each technology. Samsung also said that LG Display gave some information to a third party. In July we reported that 11 former and current Samsung employees were charged of giving LG Display confidential OLED technology, and this is Samsung's reaction in court.

It was also reported that two Samsung OLED TVs were 'lost' during the shipment to the IFA exhibition, and this may be another case of industry espionage.

Later in September LG Display responded with a counter patent-infringement lawsuit against Samsung Electronics over OLED technology. LG Display says that Samsung infringed upon seven of its OLED patents - which relate to the design of the OLED panel, the driver circuitry and device design. LG seeks damages - and also a permanent injunction against the sale of Samsung's Galaxy S3, Galaxy Note and the Galaxy Tab 7.7 in South Korea.

Samsung's Note 2's unique RGB matrix

When Samsung announced the Galaxy Note 2, with its 5.5" 1280x720 HD Super AMOLED display, I assumed it was a Pentile display. But it seems that the Note 2 actually uses an RGB matrix in a rather unique arrangement (you can see the matrix here). This is rather confusing on several accounts - mostly because up till now Samsung used the brand Super AMOLED Plus for non-pentile OLEDs.

Just a few weeks ago we explained that Pentile OLED displays enable higher lifetime , and we were told that for an RGB OLED with over 230 PPI, lifetime becomes too low for Samsung and they choose Pentile in those displays. But the Note II has a PPI of 267 - the highest PPI non-Pentile OLED. This means it has a lower lifetime compared to a Pentile display (but the advantage is that there's no visible Pentile pattern of course).

It seems likely that Samsung managed to increase the lifetime of their OLED displays, and so were able to ditch the Pentile here. It's possible that Samsung have finally started to use green PHOLED emitter (which improves the lifetime over the green fluorescent emitter used in current displays), and perhaps they have also moved to a better fluorescent blue emitter.

Another possibility is that Samsung is using Ignis' AdMo-p technology, which features a matrix that's very similar to the one used in the Note 2, and it does extend the screen's lifetime.

OLED EVFs

In the past few weeks several new digital cameras with OLED EVFs were announced: the Fujifilm X-E1, the panasonic GH3 and Sony's A99, NEX-6 and the RX-1. In the Sony cameras, the OLED microdisplays are made by Sony themselves. But who makes the other OLEDs used by Fujifilm and Panasonic?

The GH3's EVF has a microdisplay that sports 1,744k pixels - and that's all we know about it. Pocket-Lint claims that it sports an RGBB architecture (a second blue). This probably means that it is made by MicroOLED as we know they used this architecture (RGBB filters over white OLEDs) in their first-get WVGA OLED micodisplay, which fits the GH3 specification.

The Fujifilm X-E1 has a different microdisplay, an XGA one (2.4M pixels). We know that both Sony and eMagin have developed XGA microdisplays, so it may be made by either. eMagin said that they will start shipping samples in September, while Fujifilm plans to release this camera in November - which makes it unlikely that it's an eMagin microdisplay (they surely have picked a supplier already). On the other hand, the contrast of the X-E1 is reportedly 5,000:1 while the Sony microdisplays feature a contrast of 3,500:1. So it can be either company, or a different supplier altogether.

The iPhone 5

Apple unveiled the iPhone 5 - the latest generation of its popular smartphone. The new device features a light (112 grams) and thin (7.6 mm) glass and aluminum body, a fast A6 processor, LTE and a 4" 1136x640 (326ppi) Retina LCD display. It's not an OLED - and this time there weren't even rumors that Apple will use OLEDs...

DisplayMate posted a comprehensive comparison between the iPhone 5's display and the Super AMOLED on the Galaxy S3. They say that the iPhone's display is superior - its a very accurate display, and it's the best Smartphone display they have ever seen. It's actually quite an improvement over the display used in the iPhone 4S. DisplayMate says that the OLED display on the S3 is not as bright as the LCD, it is less readable in high ambient lighting, it has saturated green and distorted and exaggerated colors. They still complain about Samsung not calibrating the color gamut. On the other hand, they say that OLED is a new technology and hasn't been refined to the same degree as LCDs yet. They still say OLEDs have a very promising future.
