Power Hungry Plasma Displays to Be Banned in Europe and California

European Union and California wants to ban plasma screen televisions plasma screen televisions as they “guzzle” too much power and adds to the global warming issue.

Press Coverage on Ban: According to the Daily Express, “A 42in plasma television uses over twice as much power as a traditional television set. Some of the larger models can take as much as electricity to run a fridge freezer”.

LA Times reports that “(California) State regulators are getting ready to curb the growing power gluttony of TV sets by drafting the nation’s first rules requiring retailers to sell only the most energy-efficient models…”. The regulation is expected to pass in mid-2009. According to LA Times, “During a peak viewing time when most sets are on, such as the Super Bowl, TVs in the (California) state collectively suck up the equivalent of 40% of the power generated by the San Onofre nuclear power station running at full capacity. Televisions account for about 10% of the average Californian’s monthly household electricity bill”. Further the article goes to describe how Plasma screens are more power hungry than LCD screens.

Power Usage Comparison of Plasma vs LCD: We looked at various professional large screen displays that businesses would buy, to see if what is being reported is correct. Below we analyze some of the Plasma professional display brands against the Sharp LCD screens to understand how plasma screens compares with LCD screens. Our finding was that Plasma displays consumed almost twice as much power per display than LCD display of similar size.

Comparing Panasonic Plasma Display vs. Sharp LCD Display

· 65″ Panasonic Plasma Display: A 65inch professional plasma display by Panasonic (TH-65PF11), which is high definition display, consumes 755W of power, according to the company display brochure.

· 65″ Sharp LCD Display: A 65inch profession LCD display by Sharp (PN-S655), which is also a high definition display but using LCD technology, consumes 480W of power, according to the company display brochure.

We looked at other professional display brands to see their power consumptions.

· 60″ LG Plasma Display: LG does not offer a 65inch professional plasma display for business use. The 60inch plasma display LG plasma display (60PG70FR) uses (690W-760W) of power.

· 50″ Sony Plasma Display: The largest professional plasma display offered by Sony is 50inches (FWD-50PX3/S). The 50inch plasma display uses 440W of power compared to Sharp 46 inch LCD display using 312W of power.

Do your own analysis but it does seem that Plasma displays consume more power than LCD displays. By placing restrictions on display companies EU and California governments hope to encourage display companies to produce more efficient displays and TV screens. With the growth of flat-screen TVs, this is bound to make a difference. As consumers and the world gets more “green” conscious, it makes sense for business to be aware about recent trends as this will save them more money in the long run.

LCD Screens Transforming Digital Signage and Advertising in Restaurants and Retail Stores

It is not hard to understand why LCD displays screens are rapidly being adopted by retail stores and restaurants. InfoTrends conducted a digital signage study where they polled consumers and found that “digital signage displays have a 47.7% effectiveness on brand awareness, increase the average purchase amount by 29.5%, create a 31.8% upswing in overall sales volumes, generate a 32.8% growth in repeat buyers and generate 32.8% more in-store traffic”.

LCD display screens are being used by restaurants for displaying the menu and entertainment, by garment and clothing retail stores to show videos of fashion shows and to showcase various products, and by automobile dealers as video walls to provide the feel of the car on the road and to keep the customer occupied as they wait for sales agent or other people.

LCD Display Usage in Restaurants: When visiting KFC Hyderabad (India), what grabs your attention is not so much the smell of food but the vibrant colours of the four 42-inch LCD display panels which serves as the overhead menu board. KFC Hyderabad sought the help of Sharp Business Systems India to set up the digital signage solution. LCD digital menus can be maintained from a remote central location or a local PC set up in the store. The benefit of remote central management is that menu, promotions, video, pricing and other items displayed on the LCD displays in the retail outlet can be managed from one central location to provide consistency and to make sure that the changes are made consistently across all stores at the same time. Consumers receive dynamic previews of the offering with potential for positive impact on sales. If restaurants have the networked point-of-sale cash registers collecting time based purchased data, marketing can get instantaneous feedback on how different promotions and pricing are having impact on sales.

Restaurants are also using LCD displays as televisions to spruce up the restaurant atmosphere. It is now a common expectation to have LCD TVs in restaurants that show the local sports or the news.

LCD Display Usage in Showrooms: Whether it is women clothing store, automobile showroom, convenient store or a department store, LCD displays are appearing in all these locations. A typical store has up to four LCD displays per site. InfoTrends study showed that business that had installed displays in their showroom, predominantly expected the display usage in their showrooms to increase. To grab and hold consumer attention, retailers are using LCD displays in a video-wall format or in a daisy chain format along with stand alone units. The content could be a mixture of video along with text or a combination. The goal is to target specific customers with specific information and this information may change with the time of the day – creating a retail company-owned, closed-circuit television network that runs nothing but the retail company programming.

Why do Retail Businesses Select LCD Displays vs. Plasma Displays?
There are a number of reasons why retailers and restaurants are selecting LCD display over plasma displays.

· Fan-less Architecture of LCDs: LCD displays do not have a fan potentially resulting in less noise and distraction. This is less of an issue with newer higher end plasma displays, however it is worthwhile to keep track as you evaluate the two options.

· Rugged Design of LCDs: LCD displays are closed-box units and more rugged. There is less chance of oil fumes, dust or other elements getting into the unit and reducing the life of the unit.

· Resolution and Picture Quality: (A) Video resolution on LCD displays and plasma display are comparable but computer data is better observed on LCD displays. (B) LCDs are better to view in ambient light or in brightly lit rooms. As businesses usually work during the day in ambient light, LCDs are more desirable for most business applications. (C) Plasma manufacturers have made much of their viewing angles. However with new LCDs the view angles are 176°. There is not much difference between the two technologies in viewing angle. (D) There have been concerns with burn-in for Plasma screens especially for static images. However, many Plasma manufacturers have improved their anti-burn in technology. There are no burn-in issues with LCD screens.

· Life of the Display Unit: LCDs can be operated 24×7 for 50,000+ hours equivalent to 5+ years of continuous viewing. Plasma, on the other hand, typically has a half life of 30,000 hours. At half life, the phosphors in a plasma screen will glow half as brightly as they did when the set was new. There is no way to replace these gases; the display simply continues to become dimmer with use. An LCD TV will last as long as its backlight – and in many models the backlight bulbs can be easily replaced!

· Power Consumption: Plasma TVs use more power than LCD – twice as much

Technology for both plasma and LCD display continues to change. Be sure to check updates to the technology for apple to apple comparison.

LCD vs. Plasma Large Screens for Businesses: Why LCD wins

Businesses are rapidly adopting large high definition TVs and monitors for advertising, video conferencing, conference rooms, entertainment and information display, among other uses. We talked with a number of audio visual consultants, system integrators, distributors, vendors and customers and found there was confusion and misunderstanding as to what is better – LCD or Plasma for large screen use for various applications. Understandable, considering the rapidly evolving technologies, numerous choices, the gamut of reviews and the various applications these large screens are being used. We are hoping we can clarify but research the technologies yourself and make the knowledgeable choice.

Quick Introduction to the Technology: Plasma screens use a matrix of plasma gas cells which are charged by electrical voltage to create a picture. LCD screens are made up of liquid crystals placed between two glass plates. Below we compare the two technologies on features important to businesses.

LCD vs. Plasma Comparison: Size
LCDs are generally lighter and thinner as they don’t contain the gas-filled chambers and heavy glass panels present in plasmas. Historical wisdom was that larger size screens available were Plasma while smaller size screens were LCDs. Today, commercially, Panasonic has 103” plasma while Sharp offers 108” LCD. Smaller size Plasma screens are currently not available. A draw for large size screens. Smaller size Plasma screens are currently not available. LCD vs. Plasma for Screen Size: A draw for large size screens.

LCD vs. Plasma Comparison: Picture Quality

A number of variables go into picture quality. We will outline them and summarize the findings.

Video Resolution: High resolution is available for both Plasma and LCD screens and resolution is usually comparable for both technologies (1920×1080 is considered as high resolution and available in both Plasma and LCD screens). Lower price models for both Plasma and LCDs have lower resolution and typically for <45” screens they are 1366×768 in resolution or lower. Be sure that you compare apples to apples. Overall: A draw between the two technologies.

Data Resolution: Data resolution for LCDs is much better than for Plasma. The number of pixels per square inch on an LCD display is typically higher than any other display technology including Plasma, so LCD monitors are especially good at displaying large amounts of data. For the same reasons, LCD screens will also be better screens for video gaming than Plasma screens. Plasma displays produce a very jaggy image when viewing static images from computer images. Users may want to consider a commercial version plasma if their application calls for a lot of computer use.

Color Accuracy: Plasma color richness and naturalness will prevail in rooms with lower to normal lighting due to higher contrast ratio. LCD screen contrast ratio is relatively lower, but with anti-glare & brightness features of LCD screens, LCDs will be better in ambient light or in brightly lit rooms. As businesses usually work during the day in ambient light, LCDs are more desirable for most business applications.

Viewing Angle: Plasma manufacturers have made much of their 160° viewing angles. However with new LCDs the view angles are 158°. There is not much difference between the two technologies in viewing angle

Burn-in: There have been concerns with burn-in for Plasma screens especially for static images. However, many Plasma manufacturers have improved their anti-burn in technology. There are no burn-in issues with LCD screens.

LCD vs. Plasma for Picture Quality: LCD wins.

LCD vs. Plasma Comparison: Life of the Screen
LCDs can be operated 24×7 for 50,000+ hours equivalent to 5+ years of continuous viewing. Plasma, on the other hand, utilizes slight electric currents to excite a combination of noble gases (i.e., argon, neon, xenon), which glow red, blue, and/or green. This is an essentially active phenomenon, so the phosphoric elements in plasma displays fade over time. Typically half life is 30,000 hours but some manufacturers state a new half life of 60,000 hours. At half life, the phosphors in a plasma screen will glow half as brightly as they did when the set was new. There is no way to replace these gases; the display simply continues to become dimmer with use. An LCD TV will last as long as its backlight – and in many models the backlight bulbs can be replaced! Since this is nothing more than light passing through a prismatic substrate, there is essentially nothing to wear out in an LCD monitor.

LCD vs. Plasma for Screen Life: LCD wins.

LCD vs. Plasma Comparison: Power consumption
Plasma TVs use more power than LCD – twice as much. Plasmas use electricity to light each and every pixel you see on a screen – even the dark ones. Also, note Plasma TVs get heated up quickly and require fans to cool the TV.However, some manufacturers point out that the power use of a plasma TV is directly dependent on picture brightness, whereas an LCD picture requires a constant source of illumination. The theory goes that plasma should use less power over time. But in reality plasma TVs require significantly more power to achieve the same brightness level as an LCD. This is significant, since your investment on UPS (higher KVA) will have to be much larger to give similar backup to a system using Plasma. No wonder, IBMs & HPs never even considered Plasma for their Laptop screens!

LCD vs. Plasma for Power Consumption: LCD wins.

LCD vs. Plasma Comparison: Lightness and Versatility
Both types of flat-panel screens can be wall-mounted. Plasma sets weigh a lot more than LCD screens (even those of comparable screen-size), so setting them up or moving around could be a problem, especially wall mounting in new houses with stud walling. Further the bezel for LCD screens can be removed and a video wall solution can be created – can be quite valuable for advertising and monitoring

LCD vs.Plasma for Lightness and Versatility: LCD wins.To summarize, while for home video solutions, Plasma may be an OK choice, but for office and professional usage, LCD is definitely the correct choice!

LCD Screens For Commuter Trains (Metro) And Railway Stations

Large LCD screens can be found on the train, at the railway station and in railway control rooms. Recently, January 9, 2009, the Indian Western Railways announced that they will install 4,000 large panel LCD screens in 67 trains. The LCD screens will be installed by an OOH media company who will earn revenue from the advertisement on the screens and Western Railways will get a license fee of Rs 7 Crore (approx. US$1.75M) per year for the duration of the contract (which is 5 years). These LCD screens will play a mix of entertainment, information and advertising for 18 hours a day in all trains. LCD screens can also be found in the railway stations. Trivandrum Central, the biggest railway station in the state of Kerala in India, is considered “swanky” by most visitors as a result LCD flat screen televisions contributing to the overall look and feel.

However the LCD display needs for these railway displays are usually similar. Below we outline key needs of LCD screens for railways:

Price: Price is an important criteria however many OOH media companies, to their detriment, usually buy the cheapest LCD screen available for a given format size. Railways require rugged closed LCD displays. Buying cheap LCD displays or LCD TVs which are not closed boxes, may result in premature failure of the screen.

Ruggedness and 24×7 Operation Capability: LCD screens for railways need to be rugged. For this reason, it is important to have LCD informational displays vs. LCD TVs as LCD informational displays are fan-less closed box units that can offer protection from dust and other contaminants. Further LCD informational displays are made for 24×7 operation while LCD TVs are made for limited viewing. Ruggedness and life of the LCD screen is very important to reduce failures of the LCD screens. LCD failures will cause inconvenience to passengers and may disrupt traffic flow at railway stations.

Network Capability: Be sure that the LCD screen has RS-232 and LAN network connectivity. The network connectivity allows for remote monitoring of the various LCD screens. Alarms can be set if an LCD screen is switched off or if it is not working. Power and other controls can be monitored remotely. For example, an energy saving feature can be activated so that when there is no signal, a power save mode is activated to reduce the brightness of the LCD backlight.

Picture Quality: Most large LCDs are high definition. High definition LCDs provide better picture resolution, better contrast ratio, high brightness, high colour reproduction and fast response time resulting in better picture clarity. High definition, high brightness and high contrast ratio are important features for LCDs to have in railway environment for easy picture viewing. Further, the non glare feature of LCDs allows for easy viewing in ambient light or where there is background light being reflected on the screen. Most new LCDs have 176° viewing angle, making it easy for viewing. Check the viewing specifications to make sure meets your quality requirements

Slow-scan (legacy) Signal Capability: If the LCD screens are being installed in the old chassis of the old CRT television or in a mixed network of CRT televisions and LCD displays, the LCD screen needs to be slow-scan legacy signal compatible.

New LCD screen features are continuously emerging. Check with the LCD screen manufacturer to learn about new features. Read other articles and make the right decision for your LCD purchase.
