World’s first big-screen OLED installed in Germany

September 29, 2010

Technology breakthrough enables flexibility of size and shape

The first screen of its kind, the Diamond Vision OLED, measuring 8.8sqm (3.84 m (w) by 2.3 m (h)) with a depth of just 9.9cm, has been installed at the material Research Center recently opened by the chemical and pharmaceutical company Merck KGaA in Darmstadt, Germany.

The new technology is a pioneering step forward, using organic light emitting diodes (OLED) as a light source, which due to its structure and composition is fully scalable and can be arranged into flexible forms and shapes.

The ‘Diamond Vision OLED’ screen is located in the lobby of Merck’s new research centre. Merck KGaA is one of the leading producers of organic base materials for innovative OLED technology and will use the screen as an information system for presentations and events. It has a resolution of 1,280 x 768 Pixel and weighs around 480kg.

“OLED is literally growing in size and format and has the potential to become the technology of choice for the digital signage industry in the near future. It is a significant achievement that we have been able to develop this pioneering technology with our Japanese colleagues“, explains Lars Dörholt, Deputy Division Manager, Visual Information Systems at Mitsubishi Electric Europe’s German branch.

‘Diamond Vision OLED‘ by Mitsubishi Electric is designed for indoor use and with its newly developed picture management technology, delivers seamless and vivid images. The screens deliver a wide viewing angle of approximately ±80degrees vertically and horizontally, while generating a maximum brightness of 1.200 cd/m2. Achieving double the contrast of comparable LED products, Mitsubishi Electric’s OLED-Displays are particularly well suited for use in bright environments such as shopping malls, stations or airports.

The new screen image is composed of square modules with a standard size of 38.4 cm (128 x 128 Pixel by module). Due to the modular nature of the product there are virtually no limits in terms of size, scalability, form or design. As a result, displays no longer have to be flat, but can now cover uneven or curved/convex surfaces. Each module weighs only 8 kilograms and the minimum viewing distance could be reduced to 2meters. With a depth of only 9.9cm the OLED displays are particularly well suited for the installation in halls or waiting areas.

With its new large screen technology capabilities, developed in cooperation with Tohoku Pioneer Corporation, Mitsubishi Electric is targeting new areas of application that could never have been achieved with conventional products due to limitations in size, format, amount of light or other restricting factors.

Web conferencing helps keep England squad on the ball

June 24, 2010
England’s World Cup team are using MegaMeeting web conferencing software to help manage their World Cup 2010 campaign.

Megameeting UKAs Head of Physiotherapy for the England Football Team, Gary Lewin has a vital role in ensuring players stay in peak condition. Managing injuries and any physiotherapy required is an issue that concerns not just the England team in South Africa but also medical staff from the player’s own clubs across Europe. The internet has become an essential tool in maintaining those lines of communication.

“In preparation for the World Cup, I was constantly attending meetings,” comments Gary, “Sometimes travelling the length and breadth of the country. While a physical attendance at many of these meetings was still necessary, I wanted a way to make life easier for me and my team so this prompted me to look into online conferencing.”

Gary’s search led him to Brighton-based, MegaMeeting UK. MegaMeeting differs from other web conferencing solutions in that it is 100% browser-based, requiring no plug-ins or special hardware. Gary comments, “I was amazed at how easy it was to connect into a meeting and get a session up and running without having to download any software.” Being browser-based, MegaMeeting also avoids the compatibility problems that afflict many of its competitors. “The support and online training from the team at MegaMeeting made it very easy to feel comfortable using the software,” says Gary.

James Salisbury, sales manager for MegaMeeting UK says, “Ease of use and total reliability are MegaMeeting’s strongest features; Not everyone is an IT expert, and nobody wants to waste valuable time trying to get everyone hooked-in to their conferencing solution. With MegaMeeting, you simply click one link and you’re connected.”

Along with built-in VoIP and live video conferencing with up to 16 attendees on screen simultaneously, MegaMeeting also offers the ability to share desktops and applications, conduct live polls, collaborate on documents and many other features normally only found in far more expensive products.

Gary Lewin continues, “MegaMeeting enables me to talk to FA Premiership club medical staff in real time over the internet and allows our team here to keep up to date with any injuries and rehabilitation plans.” Using MegaMeeting, Gary and the team doctor can examine medical records held at player’s clubs for evidence of previous injuries. “We are also using MegaMeeting to keep in touch with members of staff and our families while we are in South Africa."

In celebration of England’s World Cup 2010 campaign, MegaMeeting UK is offering free trials and special discount deals on its software, which – like the Beautiful Game itself – has the power to unite the world. Visit for more details

That’s a wrap

From Electronics Manufacture & Test – 27 May 2010

Sony has developed a super-flexible 80µm-thick 4.1in 121ppi 432 x 240 x RGB (FWQVGA) pixels OTFT-driven full colour OLED display that can be wrapped around a pencil.

OTFT-driven OLED display wrapped around a cylinder with a 4mm radiusAn OTFT (Organic Thin-Film Transistor) is a thin-film transistor with organic (carbon-based compound) semiconductor. The OTFT can be directly made on a flexible substrate at low temperature below typically 180°C.
To create the display, Sony developed OTFTs with an original organic semiconductor material (a PXX derivative) with eight times the current modulation of conventional OTFTs. That figure is according to internal comparisons between OTFTs with pentacene (C22H14) and OTFT with a PXX (peri-Xanthenoxanthene) derivative. The OTFT with a PXX derivative shows hole mobility four times higher than an OTFT with pentacene and better switching performance, resulting in current density at a certain gate voltage of eight times higher than conventional pentacene OTFT.

In order to achieve this, it was necessary to develop the integration technologies of OTFTs and OLEDs on an ultra-thin 20μm thick flexible substrate (a flexible on-panel gate-driver circuit with OTFTs which is able to get rid of conventional rigid driver IC chips interfering roll-up of a display) and soft organic insulators for all the insulators in the integration circuit.

OTFT-driven OLED display wrapped around a cylinder with a 4mm radiusBy combining these technologies, Sony successfully demonstrated the world’s first OTFT-driven OLED panel capable of reproducing moving images while being repeatedly rolled-up and stretched around a cylinder with a radius of 4mm. Even after 1000 cycles of repeatedly rolling-up and stretching the display, there was no clear degradation in the display’s ability to reproduce moving images.

Sony has announced that it will proceed with the development of the solution / print based process which manufactures display devices from organic materials that can be dissolved in common solvents. This process requires fewer steps, and consumes materials and energy more efficiently compared to the conventional high temperature vacuum semiconductor process which use inorganic, silicon materials.

Telepresence system “sets new standard”

March 16, 2010

Slightly gushing and over the top presentation, but an extremely impressive technology none the less. This post from InAVate magazine

Published 09 March 2010
Digital Video Enterprises has unveiled a telepresence system that not only simulates face-to-face meetings but can display nine foot wide 3D images that appear to float in mid-air. The Immersion Room solution scooped a Frost & Sullivan Telepresence Product award.

The meeting experience displays HD 3D holographic images of people for realistic videoconferencing.
"The Award was determined after a thorough review of the competing telepresence solutions and the DVE Immersion Room clearly has set a new standard for the potential realism of telepresence communication," said Paul Waadevig, principal consultant at Frost and Sullivan. "The whole point of telepresence is to simulate a meeting where people forget about technology and get down to business. The Immersion Room is a breakthrough in simulating face-to-face meetings that, literally, makes the users forget they are not all in the same room."

Immersion Room enables life-size images of people seen standing and walking about in the 3D physical space of the meeting room. Furthermore, the Room displays nine foot wide volumetric 3D images appearing to float in mid-air. The effect does not require special glasses.
The DVE Immersion Room is based on an extensive patent portfolio of augmented reality telepresence that places real-time images of people inside the middle of the room. The inclusion of hidden cameras that aim through the image are designed to create natural eye contact.

Size DOES matter – Rapid TV News

January 27, 2010

Tuesday, 26 January 2010 20:20

Mitsubishi is about to prove that size – at least in the world of TV set sizes, does matter.

mitsubishioledscreenMitsubishi Electric says it will show a 149" prototype OLED screen at Integrated Systems Europe (ISE 2010, Feb 2-4, Amsterdam). Claimed to be the world’s first scalable OLED screen technology, the new system aroused considerable world-wide interest when it was revealed at last October’s CEATEC show in Tokyo. Mitsubishi is already a powerful name in outdoor LED screen technology with its Diamond Vision screens, and the company believes OLED has the potential to similarly revolutionise its indoor commercial displays business.

OLED screens create light by a process of electro-luminescence (EL). Each pixel consists of an anode and cathode separated by a thin organic membrane. Its simple construction means that the screen surface can be made extremely light and thin. Using specially-developed driver electronics, Mitsubishi Electric has created an edge-less OLED display module that can be joined together with others to create seamless screens of virtually any size and shape, including curves. The company believes this modular approach will deliver the versatility required of the next generation of indoor Digital Signage displays.

At ISE, Mitsubishi will demonstrate a 1920mm x 3264mm OLED display. At around 6.2m² – or 149" – this is considerably larger than any existing commercial product. A screen resolution of 1088 pixels x 640 pixels at 3mm pixel pitch delivers sharp, vibrant images, viewable even at close range.

OLED technology is claimed to be extremely versatile and offers several distinct advantages over both LCD and LED in indoor applications: Unlike conventional LED systems, its slim, lightweight construction means that large screens can be installed on virtually any building surface. Unlike LCD or plasma, Mitsubishi’s OLED modules are truly edge-less so that any shape of screen can be created without visible borders. With a light output of 1500cd/m², the production model will be several times brighter than an average LCD display, making it suitable for indoor applications in relatively brightly-lit areas. Furthermore, because it requires no backlight, the contrast performance is far superior to LCD.

Mitsubishi Electric’s OLED screen is just one of a number of new products being showcased at ISE 2010. The company will also be revealing a new LED-based projection engine for its Seventy Series display wall cubes, the L46XM, featuring a high-quality 46" diagonal WXGA (1366 x 768 pixel) LCD display with a total mullion width of 7.3mm, and a new Multi-Touch interface option for its Seventy Series display wall systems that enables multiple users to interact with a display wall simultaneously.
