  • LG Unveils World’s Largest OLED TV

    LG will present the future of TV technology at the Consumer Electronics Show in Las Vegas with the unveiling of the world’s largest OLED TV with a display size of 55 inches. By incorporating the company’s 4-Color Pixels and Color Refiner features with LG Display’s advanced OLED panels, LG OLED TV generates the most natural colors of any TV set at a much lower price point than could have been achieved using the standard manufacturing process.

    “Working closely with LG Display, we have a product which not only delivers on all the advantages of OLED over LCD but at a significantly lower cost than what could be achieved using existing OLED manufacturing technologies,” said Havis Kwon, President and CEO of LG Electronics Home Entertainment Company. “OLED is clearly the future of home TV entertainment and LG is very focused on making this exciting technology as easy as possible for consumers to embrace.”

    What sets LG’s TV picture apart from other OLED TVs is 4-Color Pixels and Color Refiner which work together to generate natural and accurate colors that are sharp and consistent. The 4-Color Pixels feature allows for more accurate color depiction by using a set of four colors (red, green blue and white) in comparison to the RGB setup used by other OLED TV manufacturers. Color Refiner ensures consistency in colors from a wider viewing angle via an LG algorithm which improves and refines hues and tones. This is in contrast to other OLED TVs which often exhibit drastic changes in hues from different viewing angles and abnormal color gamut.

    Boasting an infinite contrast ratio, LG’s OLED TV exhibits vivid colors and the smallest details regardless of the overall luminance of the on-screen image. In turn, colors and details throughout an entire image are preserved with utmost clarity and sharpness, even when displaying scenes with dark lighting. Such color capabilities are technically impossible with LED and LCD display panels. And at 1,000 times faster than LED/LCD displays, LG’s OLED TV shows crystal clear motion without any blurring or bleeding.

    And LG’s OLED TV is as aesthetically pleasing as it is technologically sophisticated. LG’s Slim and Narrow Bezel design gives the TV a sleek, minimal look and at only 4 mm thin and a mere 7.5 kg, LG’s OLED TV practically blends into the wall.

  • Sony Develops a "Rollable" OTFT-driven OLED Display

    Sony announced today that it developed a super-flexible 80 μm-thick 4.1-in 121 ppi OTFT-driven full color OLED display which can be wrapped around a thin cylinder.

    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. This was achived due to the development of integration technologies of OTFTs and OLEDs on an ultra-thin 20 μm thick flexible substrate (a flexible on-panel gate-driver circuit with OTFTs which is able to get rid of convetinal rigid driver IC chips interfering roll-up of a display) and soft organic insulators for all the insulators in the integration cuircuit.

    By combining these technologies, Sony successfully demonstrated the world’s first OLED panel which is capable of reproducing moving images while being repeatly rolled-up – around a cylinder with a radius of 4 mm – and stretched.

    The company will unveil the results of this development on May 27 at "SID (Society for Information Display) 2010 International Symposium" in Seattle, WA (May 23-28).

    This is the world’s first demonstration of an OLED display with an integrated gate-driver circuit with OTFTs. The improvement of the OTFT described above enables integration of a flexible gate-driver circuit with OTFTs on a display panel. The roll-up capability is possible because the rigid driver IC chips has been removed from the display.

    Sony informed they will proceed with the development of the solution / print based process which manufactures display devices from organic materials that are easily dissolved in common solvents. This process requires fewer steps, and consumes materials and energy more efficiently – thus has a smaller environmental footprint – compared to the conventional high temperature vacuum semiconductor process which use inorganic, silicon materials.

    The company will continue to improve the performance and reliability of its flexible organic displays because the application of these developments are expected to yield thin, light-weight, durable and mobile devices with enhanced form-factor.

  • Sony Unveils First OLED Professional Field Monitor

    Sony is bringing the stunning technology that revolutionized consumer displays to its line of professional monitors. The new PVM-740 is the first field display to use an Organic Light-Emitting Diode (OLED) display panel with Sony’s unique Super Top Emission™ technology to efficiently deliver superb high contrast, high color images, even in ambient light.

    The 7.4-inch high-resolution (960 x 540 pixels) portable monitor can fit a range of professional monitoring applications, including studio editing, ENG and EFT production, OB trucks, and even research and development. The versatile new monitor is also ideal for use in 3D camera rigs with its flip mode.

    The display panel creates smooth gradation from the dark to the bright portions of scenes such as a sunrise or a sunset. The PVM-740 offers outstanding high-contrast images – for example, the deep black of a night scene can be accurately displayed and the black portion of an image is not raised even in a low-illumination edit suite. Its blur-free, quick response to fast motion is perfect for sports or camera monitoring during panning and text scrolling.

    The monitor can flip a picture horizontally or vertically without frame delay. This feature is useful during 3D image acquisition using a 3D rig camera with a pair of 2D monitors. The monitor can be connected to the camera systems directly without need for an external signal converter, making system integration simpler.

    Its picture contrast is greater than a CRT display, is less affected by ambient light, allowing clear images to be viewed even in strong sunlight. For further protection, the optional VF-510 ENG kit provides a viewing hood, carrying handle, and connector protector.

    An AR coating provides protection from scratches and enables a high transmission rate of the internal light source to keep the picture as bright as possible, while keeping reflection from ambient light to a minimum. As a result, when used in bright lighting conditions, high contrast is still maintained even in dark areas of the picture.

    Sony’s unique 10-bit panel driver and ChromaTRU™ technologies work effectively to emulate colors and gammas of CRT monitors, and to support broadcast standards (SMPTE-C, EBU, and ITU-R BT.709).

    The new monitor also adds DC/AC operations, a convenient control panel with luminous and assignable buttons, a camera focus function, a wave form monitor, 8-channel audio level meter, a variety marker setting, and native scanning capabilities.

    The PVM-740 monitor is also equipped with a Sony’s unique feed-back circuit system. This system works to monitor the emitted lights all the time, and feed the monitor-result back and adjust the white balance. It also ensures color and gamma stability.

    The PVM-740 is 3.8U high and half-rack wide. Using the optional MB-531 mounting bracket with a 10-degree-forward and 10-degree-backward nonstop-tilt capability, two units can be installed side by side in a 19-inch EIA standard rack. With 3/8-inch and 1/4-inch screw holes on its base, the PVM-740 can be installed in a camera system on a pedestal, for example.

    The PVM-740 can display a center marker and aspect markers, and the brightness of these markers can be selected from either gray or dark gray levels. Users can also select a gray matte to fill the outer area of the aspect markers.

    A unique native scan function reproduces images without changing the input signal’s pixel count – mapping the pixel of the input signal on the panel pixel-to-pixel. For example, when an SD signal is input, the monitor reproduces the image at picture sizes of 646 x 487 pixels in 480i and 480p, and 768 x 540 pixels in 575i and 576p. When an HD signal is input, the PVM-740 displays a center portion of the HD image.

    The PVM-740 is equipped with standard interface connectors: a composite video, a 3G/HD/SD-SDI, and an HDMI interface.
    It accepts most SD or HD video formats. For extra mobility, it incorporates various video interfaces as standard, including composite, SDI interface for SD-SDI, HD-SDI, 3G-SDI, and HDMI interface.

    With the 3G-SDI interface, it accepts 1080/50p and 1080/60p formats, which is compliant with the SMPTE 425 standard, transmitting up to 4:2:2/10-bit 1080/60p and 1080/50p video data using one SDI cable. As sports and live production move toward a 1080p system, this single-link 3G-SDI system can be an ideal solution.

    HDMI connectivity further expands the monitor’s potential applications. For example, the PVM-740 monitor can connect with professional video systems such as Sony’s XDCAM HD®, XDCAM EX™, NXCAM™, and HDV™ series. Consumer video products such as Blu-ray Disc™ and digital cameras can also be connected, ideal for Blu-ray video authoring or digital photo image previews.

    The new monitor is planned to be available in April, at a suggested list price of $3,850.

  • OSRAM Sets a Milestone in Developing OLED Technology

    OSRAM Opto Semiconductors has set an important milestone in developing OLED technology. The OLED prototypes that OSRAM has developed as part of a research project are large transparent light sources only a few hundred micrometers thick.

    Thanks to new technology these organic light emitting diodes do not need separate encapsulation and can be made incredibly thin in any layout.

    The company informed that the transparent test samples have a luminous area of 210 cm² and are already showing the enormous potential of OLED light sources.

    “They offer a tantalizing glimpse of the extraordinary lighting applications that may one day become reality,” the company says.

    According to OSRAM even the 17 x 17 cm² OLED panels provide a clear indication of the direction that the OLED lighting market is taking. The demand is for large low-profile transparent light sources.

    The test samples were developed as part of the TOPAS research project funded by the Germany Ministry for Education and Research (BMBF). The aim of the project is to produce 1 m² large transparent OLED modules and will run until 2011.

    Even though the modules will have to be made larger, they already have many of the properties that distinguish OLEDs from other light sources. They are extremely slim and no longer need expensive encapsulation.

    Their thickness is now defined only by the substrate as the carrier material – at present this is between 300 and 700 µm. OSRAM promises further development work will lead to an even thinner carrier material and therefore even thinner OLEDs.

    “These low-profile OLED modules will be even easier to use in all kinds of applications. They can be made in any shape, take up very little space and can be integrated so discreetly that they are only noticed when they are switched on,” said Dr. Karsten Heuser, head of the OLED division at OSRAM Opto Semiconductors

    The OLED panels can be made transparent without any detracting structures. This is thanks to new developments in electrode design, a special component architecture and a new approach to thin-film technology.

    Without any additional conductor path structures on the light-emitting surface, the current is distributed evenly over the active surface, which in turn leads to uniform luminance.

    The new technology also simplifies the manufacturing process, whether OLEDs are produced on a small molecule or polymer basis. Irrespective of the material of the active layers, the technology can be used for colored, warm white and cold while OLEDs.

    Heuser says the next stage is to integrate the processes into a stable manufacturing operation.

  • Microsoft Unveils Zune HD Details

    Microsoft announced today that the Zune HD, its long-awaited media player, is available now for pre-order and is set to hit store shelves on Sept. 15.

    The black 16 GB version will sell for $219.99, and the 32 GB "platinum" device for $289.99. Both 16GB and 32GB capacities will be available in five different colors with the option to customize the player with one of 10 new engravings designed by guest artists.

    Pre-order starting Thursday, Aug. 13 at https://www.zune.net/zunehd and purchase in stores on Tuesday, Sept. 15.

    Those who want a sneak peek, can visit select stores in Atlanta, Boston, Chicago, Dallas, Houston, Miami, Minneapolis/St. Paul, New York, Los Angeles, Philadelphia, San Francisco, Seattle and Washington, D.C., areas on Aug. 22 and 23.

    Zune HD features 3.3-inch glass screen and 16:9 widescreen format display (480 x 272 resolution) and have HD video output to allow video to be played on an HDTV.

    It comes also with built-in HD Radio receiver, an OLED touch screen interface, wi-fi, a multi-touch UI for Internet Explorer and has access to TV, movies and games through the Xbox Live Video Marketplace.

  • Microsoft Confirms Zune HD with XBox Live Tie-In


    Microsoft is to launch the Zune HD this autumn and the device will have access to TV, movies and games through the Xbox Live Video Marketplace.

    Essentially being lined up as a rival to Apple’s iPod Touch, the new PMP will have a built-in HD Radio receiver, an OLED touch screen interface, wi-fi, a multi-touch UI for Internet Explorer.

    The new Zune will feature a 16:9 widescreen format display (480 x 272 resolution) and have HD video output to allow video to be played on an HDTV.

    While the new features are certainly an improvement on the original Zune, it will be interesting to see whether consumers like the fact a Zune dock has also to be bought for outputting HD video.

    The HDMI audiovisual docking station connects to an HDTV in 720p.

    The apparent lack of an app store also seems to be a potential stumbling block for the Microsoft device.

  • Next-Gen iPhone Will Be Modest Upgrade?


    Apple’s next-gen iPhone could be unchanged in physical design but include changes relating to speed, memory and the camera.

    At least that’s according an unnamed employee at Apple’s manufacturing partner Foxconn, who claims to have used prototypes of the handset.

    The main changes are increases in clock speed and memory: the roughly 400MHz Samsung ARM processor used in the current iPhone 3G will be upgraded to a 600MHz part, according to a post on a Chinese site

    Writing anonomously, the commentator also said that system RAM will be doubled to 256MB and the handset will ship in 16GB and 32GB configurations.

    It is also said to have a 3.2-megapixel camera with autofocus.

    While the information is unsubstantiated, if true there could be some disappointment.

    Among the improvements being sought are an improved battery, a better GPU, a more elegant housing and – ideally – an OLED display.

  • Samsung Leading Global TV Brand, Full HDTV Sets Now Fifth of Market


    Samsung has maintained its place as the world’s biggest TV brand for the third year running.

    With a 21.9 per cent market share, the South Korean electronics manufacturer is some way ahead of second placed Sony, according to DisplaySearch.

    The findings are published in the researchers latest Quarterly Global TV Shipment and Forecast Report.

    They also show that the 1080p share of global TV shipments exceeded 20 per cent of units for the first time in Q4 of 2008.

    China remained the largest market for TVs on a unit basis, accounting for just over 19 per cent, followed by Western Europe and North America at just less than 19 per cent.

    However, on a revenue basis, North America remains the world’s largest TV market despite strong quarter-on-quarter (Q/Q) revenue growth in Western Europe.

    LCD TV picked up market share in every region, with especially strong share gains in China and Eastern Europe.

    As the brand leader, Samsung remains clear at the top, holding its revenue share nearly unchanged at 21.9 per cent, more than 7 share points higher than second placed Sony.

    Sony, however, enjoyed the strongest share growth and Q/Q revenue growth among the top five.

    Samsung was also the overall unit shipment leader and was in the top three rankings in each technology category (except OLED) and led LCD TV shipments.

    Sony enjoyed strong Q/Q revenue growth, but its year-on-year (Y/Y) revenues declined by 7 per cent due to ASP erosion. LGE rounded out the top three TV brands worldwide at 11.5 per cent revenue share.

    It also maintained a very slight advantage over Samsung in the high growth emerging market segment.

    The report also showed that despite the difficult economy and concerns about consumer spending, demand for larger screen sizes grew during Q4 2008.

    The share of TVs shipped at 40"+ screen sizes reached an all-time high of 23 per cent, up from 19 per cent in Q3 2008 and 18 per cent in Q4 2007.

    This was largely the result of significant discounts by manufacturers and retailers, both hoping to avoid excessive inventory after the holidays.

    The volume weighted average price for 32"+ TVs fell 19 per cent Y/Y during Q4 2008, while under 32" was unchanged from a year ago.

    Global TV shipments fell more than 5 per cent Y/Y in the last quarter of 2008 to 57.7M units from more than 60M units a year earlier.

    This is the first Y/Y decline in total TV shipments for more than two years.

    Due to ASP declines, total TV revenues fell even more, declining by 7 per cent to just over USD $30 billion despite flat panel technologies picking up more than 10 per cent unit share.

    Combined flat panel TV revenues — which includes LCD, plasma and OLED technologies — posted the first annual decline in a given quarter, falling 3 per cent Y/Y despite 17 per cent growth in unit volume with falling prices affecting revenues.

    Globally, flat panel TV share surged from 57 per cent in Q3 200808 to 66 per cent in Q4 2008 as rapidly falling LCD prices stimulated a shift from CRT to LCD, especially at smaller screen sizes under 40".

    Annual LCD TV shipment results for 2008 as a whole were 105M units, up 33 per cent Y/Y.

    DisplaySearch said the positive results also pushed LCD TV past CRT TV worldwide for the first time on an annual basis and mark significant progress in the transition from tube to flat panel technologies.

  • New Display Technologies Stalking LCD


    Cost remains a key factor in ensuring LCD is the display of choice for most handsets.

    But a report from ABI Research suggests a number of new and not-so-new display technologies are vying for a chunk of LCD’s vast market share.

    It points out that since LCD is a mature technology, it has a cost advantage that ensures its future as the primary display technology for some time to come.

    But while LCD displays have improved greatly over the years, their performance still falls short in a number of key areas such as power consumption and readability in bright light conditions.

    Kevin Burden, ABI’s research director, said this is where new technologies are looking to capitalize.

    He said that Organic Light-Emitting Diodes (OLEDs) could be the ones most suited to take on LCD.

    “Of the challengers OLEDs are among leading contenders because of the maturity of their development and their use in other devices, such as televisions, which will strengthen their supply chain,” he said.

    Samsung recently announced plans to introduce a mobile handset on the consumer market with an active matrix (AM) OLED display.

    The SCH-W690 is a clamshell design HSDPA handset that will be introduced initially in the Korean market.

    Its significance is the incorporation of a 2.6 inch AMOLED screen with a resolution of 240×320 pixels and 262k colors.

    In contrast to OLEDs, the ABI report suggests that Qualcomm’s micro-electro-mechanical systems (MEMS)-based “mirasol” display is finding its first role in secondary screens found on clamshell handsets.

    In 2009 Qualcomm will open a dedicated mirasol display factory in Taiwan which is a major step towards ramping up its supply chain.

    E-Ink, the “electronic paper” display in Amazon’s Kindle, is also targeting the handset market.

    Though it is physically robust and boasts very low power consumption, E-Ink’s current lack of color handling and low refresh rate may limit its immediate appeal, but also has opportunity as a phone’s secondary display.

    However all these displays face one big hurdle: they cost more than LCD displays.

    The enormous volumes in the mobile phone market means that even a differential of a few cents can make the difference between adoption and rejection.

    Over time, though, prices will fall and as Burden notes: “It’s a long road ahead for these new display companies, but even a niche in the handset market could prove very profitable indeed.”

  • OLED is coming – but at a price


    As a next-generation display technology, the first OLED (organic light emitting diode) screens were never going to come cheap.

    For the introduction of the first OLED to the European market, Sony is said to be putting a €3,500 (US$5,000) price tag on its XEL-1 when it becomes available before Christmas.

    The astronomical cost, reported by OLED-Display.net, dwarfs the US$1850 paid in Japan and even makes the US$2,100 price stateside seem reasonable.

    When the XEL-1 launched in Japan it was unveiled as a kind of prototype for what could be. Sony was said to be making a loss on each set.

    While the XEL-1 has received a positive reception from consumers in Japan, expansion into other markets is sure to be slower at such elevated prices.

    Competition from Sony’s rival Samsung

    OLED TVs, which could potentially replace LCD and plasma TVs, are predicted to sell close to 3 million units in 2012.

    Samsung, which released the world’s largest OLED television at the IFA trade show in Berlin, has committed itself to
    commercial production of mid to large screens by 2010.

    “Samsung will begin commercial production of mid- and large-sized OLED televisions around 2010,” according to a statement from Samsung.

    At IFA, Samsung displayed two OLED screens – a 14.1-inch model and a 31-inch model.

    Sony had the XEL-1 and a 27-inch prototype, which was introduced at the CES in Las Vegas earlier this year.
