Blue Phase LCD Are Coming By David Barnes Insight Media A presentation at SID’s 50th Anniversary in September revealed that blue phase LCD are coming. I was impressed with early demonstrations of blue phase technology at DisplayWeek 2010 but there were several practical problems to solve and I pushed the topic to the back of my mind. Dr. Wu’s talk at the anniversary surprised me. Advances in liquid crystal formulations, electrode structures and optical films suggest that faster, lower-power LCD may arrive sooner than I thought. Dr. Wu’s students at CREOL (University of Central Florida) have worked with researchers at ITRI and with Taiwanese engineers at AU Optronics (AUO) and Chimei Innolux (CMI) to develop several solutions to the problem of LCD power consumption. In conventional LCDs, less than 10 percent of the backlight or sidelight power reaches our eyes. This poses problems for larger LCD TVs. For example, U.S. Energy Star 5.3, which became effective a year ago, limits TV power consumption to 108 watts for any HD display sized 50 inches or larger. Use of LED instead of CCFL backlights have helped brands meet that spec. A number of 50- and 55-inch sets earn Energy Star ratings today. Earning the Energy Star tag becomes more difficult as panel sizes increase, however. An 84-inch set would have to consume two-thirds less energy per square inch than a 50-inch set would to get the tag. And power efficacy is important in smaller displays also. A number of technologies have tried to take share from conventional LCD in applications such as e-Readers or other portable devices. While there has been some success, notably by E Ink, there have been more disappointments. Field-sequential color (FSC) systems for LCD that avoid the light lost in color filters have suffered from slow backlight modulation and from slow liquid crystal response. The advent of LED backlights enables FSC but conventional LC materials impede it. In addition, early advances in lower-power reflective or transflective LCD have been stymied by consumer preference for bright, full-color video. Polymer-stabilized blue-phase LCD promises to solve many of the problems that face large and small panel makers today. As Dr. Wu explained, clever mixtures of nematic host molecules, chiral dopants and stabilizing monomers can stretch the temperature range of double-twist blue phase LC operation to more than 70º C. More important, they’re fast: Switching time can be less than a microsecond! If discrete RGB (or multi-primary RGBY or even RGBW) backlights are applied, there is plenty of bandwidth for rainbow-trail-free FSC. That would eliminate need for sub-pixels. Effective aperture ratios would increase and color filter losses would be eliminated (along with their costs!). Power efficacy could increase four-fold. That would be really good news for brands planning 84-inch Quad-HD products or long-battery-life portables. In collaboration with Dr. Wu, CMI engineers invented a way to improve the optical switching capabilities of blue phase LC by forming trapezoidal pixel electrodes. Early attempts to construct IPS-type pixels with blue phase LC faced problems because of higher voltage requirements and cell-gap sensitivities. As shown in the diagram from student Linghui Rao’s paper (doi:10.1063/1.3271771), interleaved electrodes with a trapezoidal shape (a 1 micron plateau on a 2 micron base) put the blue phase crystals in the proper shape to enable fast switching at 10 Volts. The cell gap sensitivity declines also, which is always a good thing for manufacturers. As Dr. Wu explained, such electrode structures are possible, but they may be difficult to control in mass production. An AUO-sponsored project took a different approach. Rather than shape the electrodes, they chose to shape the input and output angles of light through the display cell. This method, called vertical field switching (VFS) uses optical films to guide light into the cell at an acute angle and turn it with a top film that mitigates the internal reflection problem to extract light efficiently. While it looks complex (see doi:10.1109/JDT.2011.2164236), it shifts the manufacturing problem from one of fabrication to one of film specification, which is a much easier problem to solve. That’s not all, other student have invented ways to control blue phase materials electrophoretically. Such methods could enable very low-power, color-reflective displays. I was even more surprised during Q&A on a blue-LED paper by a student of Nakamura at UCSB when Dr. Wu pointed out that polarized LED devices could reduce need for polarizer films and increase LCD efficacy even more. I almost hear Blind Lemon Jefferson playing “Ain’t Singin’ Them Blue-phase Blues No More!” Leave a Comment Share Article InfoComm Sustainable AV Award Given to Barco and Raymond Kent InfoComm International presented its Sustainable AV Technology Award to Barco and to Raymond Kent, CTS, LEED AP, associate principal, director of innovative technology design group, Westlake Reed Leskosky. The awards were presented at the InfoComm 100, a conference designed to bring together top AV industry thought leaders and volunteers. The Sustainable AV Award was created by InfoComm to this award recognize people and organizations for implementing environmentally sustainable practices in the manufacturing of products, integration of AV systems, reduction of waste in the workplace or through similar strategies. Barco has woven sustainability practices into all of its business operations. Barco’s product managers follow a “green checklist” which measures every milestone against ECO guidelines. Their products are constructed of recycled materials that are also largely recyclable at their end of life, and they have banned the use of six of the most environmentally polluting substances. In addition, Barco also uses 3D modeling for virtual prototypes to minimize waste of hard consumables. One of the most innovative programs Barco developed is an Air Traffic Control software solution that reduces CO2 emissions by enabling more efficient routing of airplane arrivals and departures. London’s Heathrow Airport has reduced CO2 emissions by 300 tons thanks in part to Barco’s program. “Barco has made incredible strides to make their company more sustainable,” said Randal A. Lemke, Ph.D., executive director and CEO, InfoComm International. “The company’s development of innovative technologies creates experiences that are both incredible and environmentally sustainable.” Raymond Kent has dedicated much of his 24-year career to the sustainable built environment. He is the chair of the Sustainable Technologies Environments Program Foundation Technical Advisory Committee and has been an active participant in the InfoComm Green AV SIG and the Center for Sustainable Practice in the Arts. He frequently gives lectures on sustainable technology and its implementation at conferences such as InfoComm, and for organizations such as the United States Institute for Theater Technology (USITT) and the American Institute of Architects (AIA/CES Provider). Most recently, Kent was one of 12 members of the InfoComm Green AV Task Force that wrote criteria for the Sustainable Technologies Environments Program (STEP). He has also published articles on sustainable topics including STEP, the new International Green Construction Code, and their effects on the AV industry. Along with his efforts at InfoComm, Kent has also pushed to teach sustainability in the performing arts through USITT, working with the organization to develop sustainability guidelines for the arts, including rental and staging. He is also a frequent resource for manufacturers on how to make their products more sustainable and has collaborated with companies on bringing products to market that use less energy, utilize recycled content, or contain feature sets that aid in lowering their carbon footprint. Kent has contributed to sustainability efforts within the workplace of Westlake Reed Leskosky (WRL). As Director of the Innovative Technology Design Group (ITDG), he has led the charge to implement technology design standards within WRL’s projects and practice that focus on sustainability. This includes working to reduce the amount of design documentation for systems design; pursuing with the ITDG designers ways to reduce, reuse, and recycle systems equipment in their designs; and designing smart systems that use less energy and require less infrastructure. WRL’s technology specifications include language to require systems integrators to recycle or re-purpose existing electronics that are no longer to be used in renovation projects as well as requiring proper waste management of the construction process. “Raymond Kent has been an incredible role model for all who are interested in technology sustainability,” said Lemke. “He is very willing to lend his expertise beyond his company and client lists, to benefit the entire industry. InfoComm and STEP would not be nearly as successful without his guidance and positive energy.” Leave a Comment Share Article Christie Ships G Series Projectors Christie is shipping its new G Series projectors, announced last month.

Acer Debuts World’s First LED/Laser 1080p Projector Acer is introducing the K750 is the world’s first 1080p projector using hybrid laser-LED light technology. Similiar to the technology Casio uses in its GreenSlim line of projectors, the K750 projector uses both LED and laser light sources that are free of hazardous substances like mercury or halogen gases, yet, according to the company, also improve color brightness when compared to high-pressure mercury lamps (white is whiter). This technology also increases the light-source lifetime to 20,000 hours in Extreme ECO mode and enables, says Acer, as much as 90 percent power savings (helping to reduce total cost of ownership and probably making the K750 one of the most environmental friendly projectors). With a brightness of up to 1,500 lumens and a contrast ratio up to 100,000:1, this hybrid light-source technology enables flexible color settings and a wider color gamut to deliver color saturation up to 85 percent NTSC and offers color fidelity through a system of three independent color lighting sources. This projector is so new it’s not on Acer’s website yet. But, when it is, it will be here: http://us.acer.com/ac/en/US/content/group/projectors Leave a Comment Share Article NEC Upgrades LED-Based E Series NEC Display debuted a third generation of its commercial-grade E Series monitors this month in the form of new 32-inch (E323), 42-inch (E423), 46-inch (E463) and 55-inch (E553) models.

All three are specified at 2,800 ANSI lumens and a contrast ratio of 13000:1, claiming a lamp life up to 6,500 hours. The difference is in resolution: SVGA (MS517), XGA (MX518) and WXGA (MW519). All include HDMI 1.4 inputs, VGA ports as well as network and RS232 control. So, what is defined as “EcoSmart”? When you put the projectors in “SmartEco” mode, they automatically adjust the lamp power to maximize power savings by delivering the best contrast and brightness performance using only as much light as needed, based on ambient light. And, if you disconnect a source (or switch to a blank input) the projector automatically lowers brightness another 30 percent after three minutes. There’s also an “Eco Blank” mode where users can blank screens when not in use to lower light source power consumption to only 30 percent, useful for when the audience’s attention needs to focus on material other than the projected image. The BenQ MS517, MX518, and MW519 retail at $449, $549 and $649, respectively.

RealPresence CloudAXIS is software suite that runs on the Polycom RealPresence Platform in either private enterprise clouds or public clouds, and securely extends enterprise-grade video and content collaboration outside the firewall to other businesses (B2B) and consumers (B2C) via a browser. The RealPresence CloudAXIS Suite is ideal for Polycom dealers to expand from offering Video-as-a-Service (VaaS) to Video Collaboration-as-a-Service (VCaaS) — adding applications such as recording and streaming, web conferencing, and collaboration tools (e.g., digital whiteboards). RealPresence CloudAXIS also offers additional value for large enterprises with the RealPresence Platform, enabling customers to create private enterprise clouds to extend video collaboration to other businesses and consumers for B2B and B2C connectivity. Polycom says that RealPresence CloudAXIS Suite eliminates the security risks and administrative headaches posed by third-party video clients and solutions introduced onto corporate networks by employees who communicate over unsecure connections. RealPresence CloudAXIS also enables enterprises to leverage their investment in existing standards-based Polycom video collaboration systems — including room/group, desktop or mobile video solutions — and the RealPresence Platform. RealPresence CloudAXIS Suite fast-tracks dealers that want to get to market quickly with new subscription-based revenue streams via both B2C and B2B VCaaS offerings. VCaaS enables dealers to offer value-added applications on top of cloud-delivered video conferencing, including recording and streaming and web conferencing, plus collaboration tools such as digital whiteboards and collaboration apps for vertical markets like healthcare or education. This offers opportunities to dealers to drive more monthly/annual service subscription sales, which are a key profit center for AV dealers. Dealers can even co-brand the experience, including the user interface, and by leveraging Polycom’s recently announced suite of open APIs for the RealPresence Platform, they can integrate the RealPresence CloudAXIS suite with operations and billing support systems (OSS/BSS), as well as create unique value-added enterprise or consumer applications. The RealPresence CloudAXIS Suite consists of a global directory presence engine, web client (supports HTML5-compatible browsers) and what Polycom is calling a “flexible resource broker” that dynamically allocates and brokers crucial variables such as bandwidth, databases, sessions and media to ensure an optimal user experience. Polycom plans to make trials of the RealPresence CloudAXIS Suite available to service providers in Q1 of 2013.

For those of you NEW to rAVe, you just read how we are — we are 100 percent opinionated. We not only report the news and new product stories of the ProAV industry, but we stuff the articles full of our opinions. That may include (but is not limited to) whether or not the product is even worth looking at, challenging the manufacturers on their specifications, calling a marketing-spec bluff and suggesting ways integrators market their products better. But, one thing is for sure, we are NOT a trade publication that gets paid for running editorial or product stories. Traditional trade publications get paid to run product stories — that’s why you see what you see in most of the pubs out there.
