GeekAmmo launched a successful Kickstarter campaign that aims to develop a tiny Arduino computer with a built-in PMOLED display. The MicroView will be the first small Arduino that has a built-in display, so you do not need to connect it to a computer for output.

The Microview uses a ATmega328P CPU (16 Mhz), 32Kb of FLASH and a 64x48 blue PMOLED display. The inventors wanted to reach $25,000, but with 21 days to go, they already raised over $300,000 as this campaign got a lot of press and almost 4,000 backers.

Samsung's Galaxy S5 is launching, as planned on April 11, and now Amazon offers the AT&T model for pre-order. Depending on the service plan, the GS5 costs $189.99 to $699.99.

The GS5 features a 5.1" FHD (432 PPI, Diamond Pixel most likely) Super AMOLED display, a 2.5 Ghz quad-core CPU, 2GB of RAM, 16MP camera (4K video support). The GS5 is dust and water resistant, and it packs a finger scanner and a heart rate sensor.

A couple of months ago we reported that printed electronics developer Plextronics filed for chapter 11 bankruptcy protection as they failed to find a buyer or an investor.

Today Solvay (an investor in Plextronics together with Samsung and Universal Display) announced that they acquired Plextronics. Solvay did not reveal the financial details but in January it was reported that Solvay offered $24 million to extinguish debt and $8.5 in cash to acquire the company.

LG Chem announced the world's largest OLED lighting panel at 320x320 mm (and it's only 1 mm thick!). The N6SD30 features 60 lm/W, 850 lumens brightness (max 1,000), a high CRI (>90) and a color temperature of 3000K.

The lifetime of the N6SD30 is 40,000 (LT70) at 3,000 cd/m². LG Chem says they managed to extend the panel's lifetime (compared to their older panels) mainly by using the company's own  Face Seal encapsulation technology. In fact, LG Chem upgraded all of their OLED panels to feature this new encapsulation and so all of their panels now feature 40,000 (LT70) lifetime hours.

DuPont developed new screen-printable nano-silver conductor ink that can be used to make grids and bus lines for OLED lighting panels. DuPont says that these materials are less expensive compared to materials currently used for such panels, and they offer a simpler manufacturing process.

DuPont estimates that these new inks will be commercially available next year. The inks provide extremely high conductivity and excellent adhesion even after substrate cleaning steps. They can be used on glass and flexible polymer substrates such as DuPont's own Kapton polyimide films and polyethylene naphthalate (PEN).

A few weeks ago I learned that LG started to market the G Flex smartphone here in Israel. I contacted LGE and they got the Israeli carrier Partner to send me a review unit. First of all - thanks guys!

So I switched phones, left my new GS4 behind and started using the G Flex. Here's a short hands-on review of this phone. Or actually, this isn't a real review - I mostly want to discuss the screen and my experience with this phone. There are many good reviews of this phone online already (here's Engadget's for example). I won't be showing you a video of how it flexes a little - it's been done.

A few days ago Motorola unveiled an upcoming smart watch called the Moto 360. This device (which uses Google's new Android Wear OS) is, in my opinion, the first good looking smart watch or wearable device.

Now there are reports that the Moto 360 uses an OLED display. This makes a lot of sense. This will be an always-on watch, and at least according to photos, the default analog-watch display will be mostly black. So an OLED will be much more efficient than an LCD.

Transparent OLEDs are being developed for years now - and some small PMOLED ones are being produced in low volume. But besides a few novelty feature phones, we haven't yet seen a real application for those kinds of displays. Samsung and others have been teasing us with those concept transparent flexible OLED light tablets, but finding real world applications for transparent displays isn't that easy.

Samsung now filed a patent that describes a digital camera that uses a transparent display. The screen is located to the side of the camera which makes it rather wide. What it is good for? According to the patent filing, the idea is that by using a transparent display, the subject of the photo can look at the one taking the photo - and so they can have direct eye-contact.

Earlier this month I posted that LG slashed the price of their curved 55" OLED TV to $5,999. At least that's the price now in Amazon.com. But it turns out (thanks Cooters!) that you can buy this TV at a much lower price at eBay.

If you search eBay for LG's 55EA9800 TV, you'll find several sellers offering a brand new TV (still in its original package) - for as low as $4,380. That's far below LG's original price in august 2013 ($14,999)...

In January Oculus VR unveiled their latest HMD prototype, which adopted a low-persistence OLED display. Today Oculus started accepting pre-orders for the second-gen development kit (called DK2) - which adopts the new OLED. The DK2 costs $350 and will ship in July.

Oculus said that they chose the OLED because they really want a low persistence display. They say that "it’s incredible the difference low persistence makes... It’s mind-blowing". The OLED display runs at a high refresh rate - it switches in well under a millisecond - faster than any LCD monitor on the market. In fact, the company says that the OLED they use is much faster than any other OLED panel on the market.
