LG launches their flexible OLED smartwatch in Korea, you can buy it in the US for $398

LG released the G Watch R smartwatch last week in Korea (for 352,000 Won, or $330). A Korean retailer is now offering this circular flexible OLED Android Wear smartphone in the US via Amazon.com for $398.

The G Watch R uses a 1.3" (320x320) flexible plastic-based OLED panel, Android Wear OS, a 1.2 Ghz Snapdragon 400 CPU, 512MB of RAM and 4GB of storage. It has a 410 mAh battery which should last about a single day.

Nanomarkets: LCD to dominate the transparent display market in the next few years, but OLED adoption will rapidly pick up

Nanomarkets released a new report covering the transparent OLED display market (Transparent OLED Displays – 2014) in which they forecast that the market will be dominated by LCDs in the next several years, but OLED participation will rapidly pick up. By 2019, transparent OLED display sales will reach almost $150 million, and this will grow to almost $700 million by 2021.

There are still some major challenges on the road to transparent OLEDs, but these issues are gradually being solved. The major challenges, according to Nanomarkets, are ITO replacement and excessive light loss compensation.

Interview with AIXTRON's biz-dev director as the company moves into large-scale OVPD equipment

Germany-based AIXTRON is a leading deposition equipment provider for the semiconductor industries - used for a wide range of applications, from LED to graphene deposition. For the OLED market, Aixtron is offering Organic Vapor Phase Deposition (OVPD) equipment (which was exclusively licensed to AIXTRON by Universal Display).

Juergen Kreis, AIXTRON's Director Business Development, was kind enough to update us on Aixtron's OLED business and answer a few questions we had on the company's technology. Juergen joined AIXTRON in 2010 as Director Business Development with special focus on the portfolio for organic material deposition solutions.

Q: Hello Juergen. Can you give us a short introduction to AIXTRON's OLED related products and services?

AIXTRON’s core expertise clearly is in the offering of proprietary process solutions for the deposition of organic thin-films, with OVPD (Organic Vapor Phase Deposition) and PVPD (Polymer Vapor Phase Deposition) being the core process technologies. As the fabrication of organic electronics requires many manufacturing steps, flawless integration of the respective processes into an automated material flow is essential.

Samsung may introduce cadmium-free quantum dots LCD TVs in 2015

Samsung is still on the side lines regarding OLED TVs, and reportedly the company is aiming to produce quantum-dot enhanced LCDs soon. One of the problem with QDs is that they include Cadmium, and now the Korea Times says that Samsung is collaborating with Dow Chemical to develop cadmium-free displays.

According to the report, Samsung Electronics aims to introduce the first cadmium-free QD TV in 2015. Dow chemical already started to produce the cadmium-free QD materials in its Korean's plant.

SDC shows how OLED's emissive nature can enable new innovative display modes

Samsung Display introduced three new special displays modes enabled by AMOLED technology - an ultra power-saving mode (already used in some of their smartphones), color weakness mode and super dimming mode. These are great examples how OLED's emissive nature can be used for innovative solutions.

The color weakness mode can help people with color vision deficiency to distinguish red and green clearly - by inceasing (or decreasing) the brightness of the red and green subpixels.

Graphene to enable simple electrochromic displays?

An LCD works by selectively blocking light from a backlighting unit (BLU, usually made from LEDs) using a crystal which changes its polarization-filtering when voltage is applied. An electrochromic device is similar in idea but more simple as they can be turned from being transparent to being opaque. These kind of displays haven't been commercialized successfully yet due to fragile materials and material mismatches with the electrodes.

 

But new research at Bilkent University shows that graphene can be used to create such a device that features high percentage optical modulation, optical tuning properties in the UV to infrared, good electrical conductivity with no material mismatches. The display is mechanically flexible.

New OLED gadget: Garmin Vivosmart

Garmin's Vivosmart is a smart band that includes a fitness tracker and notification display from your smartphone (iOS and Android). The Vivosmart uses Futaba's flexible (curved) 1.4" 128x16 white PMOLED panel.

This device can count your steps, monitor your sleeping and calories burned and also measure the distance you've walked. The band is powered by low-energy bluethooth and can last seven days between charges. It is also waterproof up to 50 meters and is compatible with heart rate monitors and bike speed sensors.
