According to a market analyst, sales of Samsung's GS6 and GS6 Edge are off to a good start, with over 6 million phones sold by the end of April, less than a month after the official launch. The GS6 and GS6 Edge together have fared better in the first 20 days compared to the GS5 sales back in 2014.

The same analyst says that the GS6 outsold the iPhone 6 and iPhone 6 plus during the launch. The main problem is the supply issues of the GS6 Edge - we know that Samsung Display cannot make enough flexible displays, although reportedly it has started production in their next Gen-6 fab earlier than planned to meet demand. The GS6 is expected to sell over 50 million units by the end of the year - better than the GS4 that sold 45 million units in the same period - and was Samsung's best selling phone ever.

FlexEnable and Chunghwa Picture Tube (CPT) demonstrate an OTFT full-color flexible AMOLED display manufactured by using FlexEnable's low-temperature process and CPT's RGB OLED technology.

The glass-free prototype display (which you can see above) is a full-color AMOLED that operates at 60Hz and is only 125 microns thick. This is a great achievement, but it's not clear whether CPT aims to commercialize such displays any time soon.

Back in 2013, Fujifilm and imec jointly developed a new process to deposit and pattern OLED materials using existing i-line photolithography equipment. The two companies have now demonstrated a full-color photoresist OLED. They say that this could lead to a new process that can be used to produce high-resolution large-area OLED displays in a cost-effective way.

In the new prototype, the two companies patterned red, green and blue OLED materials to create a subpixel pitch of 20 micrometer. The full device is 40x40 pixels and achieved a density of 640 PPI. As you can see in the image above, UV rays were used to confirm the result.

Corning announced an updated version of their high-performance (LCD and OLED) display glass substrate, the Lotus NXT Glass. The new glass improves the 2nd-gen XT glass (launched exactly two years ago in May 2013) with lower total pitch variations.

The new glass has improved stability, and better total pitch variation performance. According to Corning, this enables display makers to produce more efficient displays (up to 15% lower power consumption), or higher resolution displays (by up to 100 additional pixels per inch). The Lotus NXT can also improve display production yields - by up to 1.5%. It's not quite clear if these numbers refer to the improvement over Lotus XT or other glass substrates on the market

A couple of weeks ago LG Display demonstrated 0.97 mm thick 55" OLED panels that stick to the wall using magnets. Several people told me they don't think this is real, but here's a video showing this display in action:

This is currently just a prototype, but hopefully LGD will manage to commercialize this panel soon. Towards the end of the video you can see that the panel (which weighs less than 2 Kg, by the way) is connected to the wall-mount using a small cable. The video also shows the new convex OLED panel prototypes.

Alkilu was established in 2013 with an aim to develop innovative consumer OLED lighting products, and the company unveiled their low cost OLED products at CES 2014. While some of their products are already shipping, Alkilu now launched a Kickstarter campaign for the TripLit portable OLED light.

The TripLit OLED panel is about 100x100 mm in size, and has a color temperature of 3000K (yes, that's all we know). The TripLit has a Li-Polymer battery that lasts for more than 30 hours (coupled with a solar charger, this is pretty neat). As part of the campaign, you can get it for $61.

Kateeva and DuPont announced that they will co-develop solutions for ink-jet printed OLEDs - specifically they will optimize DuPont's soluble materials for Kateeva's inkjet systems. The two companies hope this collaboration will enable then to offer a simple and highly-effective OLED TV printing process.

This follows Kateeva's agreement with Sumiomo Chemical that aims to pair Sumitomo's PLED materials to Kateeva's YieldJet OLED ink-jet printing platform.

The Korea Times posted an interesting interview with Merck's OLED unit VP, Dr. Udo Heider. Udo is 'pretty confident' that Samsung will soon start producing OLED TVs again.

In the past few weeks we heard several conflicting reports on Samsung's OLED TV program. Some say they will abandon OLEDs completely (and go for QLED TVs instead), while other reports say that Samsung will soon re-enter the OLED TV market. Last year Merck stated that Quantum Dot based TVs, unlike OLEDs, are no game changer.

AU Optronics says that their 1.4" circular AMOLED display is now in mass production. The company already said before it was qualified by a Tier-1 Chinese customer - which could mean Huawei with their circular 1.4" AMOLED smartwatch. AUO also demonstrated a new 1.3" circular flexible AMOLED on a plastic substrate that is only 0.25 mm thick.

Interestingly, AUO is also developing flexible LCDs. The company demonstrated a 3.5" flexible LCD (shown below) that is based on a plastic substrate - and has a curvature of 44 mm.
