CD-Making Alloy Key for Future Displays?

  • PDF

One of the alloys found in CDs and DVDs might be key for the thin and flexible displays of the future-- University of Oxford researcher discovered one can "draw" images on a thin layer of GST alloy sandwiched between two transparent electrode layers.

Flexi displayGST (aka Ge2Sb2Te5 or Germanium-Antimony-Tellurium) alloy is a phase change material (PCM), meaning it is able to change between two states with the application of heat, light or electricity. It finds use in rewritable CDs and DVDs, where laser pulses cause it to switch between amorphous and crystalline states.

"We didn't set out to invent a new kind of display," research leader Professor Harish Bhaskaran says. 'We were exploring the relationship between the electrical and optical properties of phase change materials and then had the idea of creating this GST "sandwich" made up of layers just a few nanometres thick. We found that not only were we able to create images in the stack but, to our surprise, thinner layers of GST actually gave us better contrast. We also discovered that altering the size of the bottom electrode layer enabled us to change the colour of the image."

According to the researchers tiny PCM stacks can be turned into "nano-pixels" measuring just 300 x 300 nanometers. One can electrically switch these on and off at will to create the building blocks of a high-resolution display technology.

Europe and S. Korea Team Up in 5G

  • PDF

In an effort to provide the European continent with faster mobile internet in the near future the European Commission (EC) strikes a "strategic cooperation" deal with S. Korea to share 5G research and resources.

S. Korea EUThe agreement, or "Joint Declaration on Strategic Cooperation in Information Communications Technology (ICT) and 5G," covers the development of so-called "Net Futures" (5G, network and communications and cloud) and includes the signing of a memorandum of understanding between the EU's 5G Infrastructure Association and S. Korea's 5G Forum.

It follows a November 2013 collaboration agreement, and will eventually see the launch of jointly funded R&D programs during 2016-2017.

The 5G Infrastructure Association counts Alcatel-Lucent, Atos, Deutsche Telekom, Ericsson, Nokia, Orange, Telecom Italia, Telenor and Telefonica as members.

GSMA Calls for Further Telecoms Reform

  • PDF

In reaction to recent Telecoms Council meetings, the GSMA demands the European Commission (EC) accelerates work on the broader reform of EU electronic communications regulatory framework.

Telecoms single marketCurrently the European Parliament proposes traffic management should be restricted to a "very narrow set of circumstances," which the GSMA says constrains the development of new services, limits consumer choice and restricts the way operators ensure the internet continues to works.

In other words the GSMA says net neutrality is actually something of a hindrance for mobile providers.

Furthermore according to the organisation reform should bring further harmonisation across EU member states, eliminate outdated and unnecessary regulation and present consistent rules irrespective of technology in use.

A 10.1-inch, 4K Resolution Tablet Display

  • PDF

Japan DisplayJapan Display ships samples of a 10.1-inch LCD display offering resolutions of up to 3840 x 2160 (aka "4K") and 438 ppi pixel density for use in larger mobile devices.

The panel builds on an earlier 12.1-inch 4K panel from the company-- and, more crucially, promises to sip as much power as the 10.1-inch 2560 x 1600 displays already found in a number of tablets.

Europe Pushes Common Chargers

  • PDF

The European Parliament agrees with the introduction of common chargers as MEPs back an amended regulation demanding mobile phone makers to provide a common battery charger fitting all devices.

Chargers"The modernised Radio Equipment Directive is an efficient tool to prevent interference between different radio equipment devices," rapporteur Barbara Weiler says. "This serves the interests both of consumers and the environment."

The regulation is still in draft form, and requires approval from the European council of ministers. The European Commission also needs to decide which types of radio equipment it applies to-- as well as mobile phones the term "radio equipment" covers GPS units and wireless door openers, among others.
