Nokia: OLED company spotlight

Nokia was once the world's leading mobile phone company. They were late to the smartphone revolution, and the company's mobile phone arm was sold in 2013 to Microsoft. The Nokia phone brand was sold by Microsoft in 2016 to HMD Global, a new company founded by ex-Nokia executives.

Nokia's first OLED phone

Back in 2006, Nokia introduced the 6215i phone that was actually a re-branded clamshell Pantech PN-315 handset, for the Verizon network in the US. The phone had a 65K, 97x64 PMOLED subdisplay.

Nokia AMOLED phones - past and present

In its Symbian days, before the rise of the modern smartphone, Nokia released several AMOLED Symbian phones to the market - such as the N85 and the N86, the N8 and the E7 and the C7. In most of these AMOLED phones, Nokia used their ClearBlack Display technology (CBD) - which adds a polarized filter to the AMOLED and is said to deliver better outdoor visibility.

When Nokia abandoned Symbian in favor of Microsoft's Windows Phone OS, they continued to use OLED displays in most of their phones - the latest one was the Lumia 930, the flagship 2014 Windows Phone 8.1 smartphone. The Lumia 930 has a 5" Full-HD Super AMOLED ClearBlack display, a 2.2 Ghz quad core CPU, 20 MP PureView camera (with optical image stabilization), Qi wireless charging and NFC.

HMD Global, who now owns the global Nokia smartphone brand, has released several new smartphones - one example was the Nokia 8 Sirocco in February 2018 - with its flexible (edge-type) 5.5" 1440x2560 (534 PPI) P-OLED display - reportedly made by LG Display. In 2022 the company announced the X30 Android smartphone, with a 6.43" 90Hz 1080x2400 AMOLED display, a Qualcomm Snapdragon 695 chipset, 6/8 GB of RAM, 128/256 GB of storage and a dual camera setup. The X30 is shipping, starting at around $500 (Note: link to Amazon.co.uk).

Nokia OLED research

Nokia was also engaged in high-end OLED research. In June 2014, for example, Japan's Semiconductor Energy Laboratory, in collaboration with Nokia unveiled a new foldable OLED display - see image below.

The latest Nokia OLED news:

Nokia patents a flexible transparent self-charging photon battery

Samsung SDI and LG Chem are already developing bendable Li-Ion batteries, but Nokia is aiming higher: the company recently filed a patent for a graphene-based flexible transparent self-charging photon battery. This is still very early technology probably, and we're not sure if the company actually aims to commercialize it, but it's still exciting.

Nokia's battery design can regenerate itself immediately after discharge through continuous chemical reactions, without an external energy input - just from the humidity in the air). This could prove to be a truly energy autonomous device.

SEL shows a 8.7" FHD touch tri-folded AMOLED prototype

In June 2014, Japan's Semiconductor Energy Laboratory (SEL), in collaboration with Nokia, unveiled new foldable OLED display prototypes - 5.9" 1280x720 (249 PPI) ones, which can be folded in two or in three (these were two different prototypes).

SEL foldable OLED prototype

Last month in Japan SEL unveiled new prototypes. The new panels are bigger at 8.7" and offer a higher resolution (1920x1080, 254 PPI). The new panels are also touch-enabled. And they are still tri-folded like the ones shown in June.

SEL and Nokia developed foldable OLED prototypes

Semiconductor Energy Laboratory, in collaboration with Nokia developed a new foldable OLED display. The companies are demonstrating two display prototypes. Both displays are 5.9" in size with a 1280x720 (249 PPI) resolution. One of them can be folded in two (like a book) and the other can be folded in three (seen in the video below).

Those flexible OLED displays use a white OLEDs with color filters (WOLED-CF) design. To produce the display, SEL deposited the organic and color filters layers on a glass substrate, which is later peeled off and replaced with a flexible substrate. The displays can be bent up up to a curvature of 2 mm (two-folds) or 4 mm (three folds). SEL says that these displays can be bent more than 100,000 times.

My Samsung Galaxy S phone display died...

Samsung and LG Display are showing these cool unbreakable OLED panel prototypes, and just in time I dropped my Galaxy S phone and the display broke - So, now I also understand why an unbreakable display is good. Until I get a new phone, I'm now back to my old Nokia 1202. A phone with real buttons and a battery that lasts for days. How charming!

So. If any phone maker has a spare phone with an OLED display (hint hint, samsung), I'd be happy to get a unit for a review here on OLED-Info. It'll spare me the decision of which phone to buy...

Conflicting reports regarding AU Optronics' OLED production status

There are some new conflicting reports regarding AUO's OLED program. According to Digitimes, AUO is still struggling with technology issues (mostly low yields and costs) - and has only managed to produce 126 PPI displays. It's possible that all through 2013 AUO will only be able to make these low density panels, and so only target the entry-level and mid-range mobile phone markets. According to digitimes high-resolution OLED panel orders will go to Samsung instead. Yields at the AUO line is still low at 30%-40%.

According to Chinese site OLEDW, however, AUO managed to overcome the yield issues (reached 60% yield), and HTC will use AUO's 4.65" OLED panels in their upcoming M7 flagship phone (Digitimes says that HTC decided to use Sharp-made LCD panels instead). These 720p panels will sport a high 317 PPI (this panel was unveiled by AUO back in October 2012). OLEDW claims that HTC requires a monthly supply of 2 million panels, and have reserved the entire line output of AUO's 3.5-Gen Linkou, New Taipei City fab (7,000 substrates a month, which is not enough for 2 million panels actually, so some of OLEDW numbers aren't correct). This was already reported several times in the past.

DisplayBank: AMOLED shipments grew 8% in Q2 2012

IHS DisplayBank say that AMOLED shipments grew 8% in the second quarter of 2012, after decreasing slightly (2.5%) in the first quarter. Total shipments in Q2 were a little over 35 million units. Average size and price increased by about 1% of Q1.

DisplayBank says that Samsung is still the main supplier with over 90% of shipments, and this is not really news. They say that LG Display faced low demand from their main customers (LGE and Nokia).

Nokia announces Windows 8 phones, one with an OLED, one with an LCD

Nokia announced two Windows Phone 8 devices today. The lower-end one, the Lumia 820 has a 4.3" 800x480 Clearblack OLED display. Other features include a 1.5Ghz dual-core CPU, 1GB of RAM, 8GB of storage (and a microSD slot) and a 8mp camera. The Lumia 820 will ship towards the end of 2012.

The second phone is the flagship Lumia 920, which unfortunately does not have an OLED. It does have a very good LCD though - 4.5" WXGA (1280x768) resolution. Nokia claims that this new LCD is the brightest one on the market (25% brighter in fact than anything out there) and it's also the fastest LCD Nokia has ever shipped on a smartphone. Other features include a 1.5Ghz dual-core CPU, PureView 8mp camera (with hardware stabilization and good low-light capabilities)

AUO still faces low yields, delays AMOLED production to Q3 2012

AUO was supposed to start producing 4" to 5" AMOLED panels in Q2 2012, but new reports say that AUO's yields are still very low (less than 20%) and so they have delayed mass production to Q3 2012. The same reports suggest that AUO got orders for 4.3" qHD AMOLED panels from HTC and is likely to get orders from Nokia as well.

AUO first AMOLED plant is a Gen-3.5 fab that has a monthly capacity of about 8,000 substrates. The company is also planning to later start producing at their Singapore Gen-4.5 fab (at AFPD). According to the new reports, the company was considering a 5.5-Gen AMOLED fab as well, but isn't likely to go ahead with that plan due to the low yields from the 3.5-Gen fab. Earlier reports suggested that AUO was considering a 6-Gen fab for large size panels (for OLED TVs).
