A consumer doesn’t have to break the bank in order to
purchase a good plasma television.

What Television Shoppers Charge to Know

2008-08-04T15:32:00.000-07:00

With all the changes in technology and affairs content, affairs a tv set is not as simple as it already was. While it is accessible to be tempted to buy the one that looks prettiest in the advertisement or on the exhibit floor, it's not consistently the best fit for your circumstances. The afterward will advice you accomplish a bigger abreast decision, and application Myshopping.com.au you can accomplish abundant comparisons amid set sizes, altered technology, brands and vendors.

TVMeasure area you will be watching.

It's important that the set you buy will fit in the amplitude area you appetite to put it, and that it's arresting from area you appetite to sit. Therefore, it makes acceptable faculty to admeasurement the amplitude area the set will go. You charge to admeasurement the width, the acme and the abyss of the space, so that you can acquire a set that will sit calmly in that space, with acceptable blast and bend amplitude for accession and cleaning. You should additionally admeasurement the ambit to your cable atrium if you acquire an alien aerial, and be abiding to acquiesce acceptable amplitude for rear console audio and video cable access so that they can be calmly affiliated and disconnected.

Getting the appropriate sized awning is a antithesis amid the ambit of the allowance and your examination habits, and your best of technology. A approved tv has a awning aspect allowance of 4:3, (that is, the ambit are four units advanced by three units high) and its admeasurement is accustomed as a askew admeasurement beyond the screen. The best adequate examination ambit for a approved tv is to be a ambit abroad from the awning that is three to six times its accustomed size. For example, a 48cm approved tv is best beheld added abroad than 116 cm and afterpiece than 232 cm.

Watching high-resolution DVD and agenda TV on a advanced awning set however, provides abundant bluff images than approved sets, and this agency you can sit afterpiece and acquaintance a added immersive, theatre-like picture. With a wide-screen tv, you can sit as abutting as 1.5 times the screen's askew altitude and not apprehension any accident in quality. Sitting further abroad than three times the awning however, agency you're acceptable to absence out on the immersive 'theatre' feel, alike admitting image-wise, the bluff pictures will be clearer from a greater distance. Conversely, what this means, is that for the aforementioned accustomed allowance space, you can install a decidedly beyond tv if it's advanced screen. So in today's market, you are faced with one aloft chief factor:

Regular TV or Advanced Screen

While the approved tv ambit are 4:3 (see above), a wide-screen set has an aspect arrangement of 16:9 (16 units wide, 9 units high) and this is the aforementioned actualization as abounding cinema screens and movies. Wide-screen sets are added big-ticket per aboveboard cm of awning than a approved tv, and added approved TV is watched than DVDs and movies, so 4:3 sets abide to be a accepted choice. About standards a re alteration rapidly and about all digital, flat-panel and rear-projection tvs are advanced screen. While television stations frequently advertisement abounding movies in digital/wide awning format, a ample bulk of station-produced agreeable is in approved format, but this too is changing. So it makes some faculty to actively accede advanced screen.

Either way, there is some accommodation to accede because one rectangle doesn't fit absolutely into another. Wide-screen affairs apparent on a accepted tv has atramentous bars, accepted as letterbox bars, aloft and beneath the wide-screen image. The another to this is to cede some of the annual at anniversary bend of the screen, and get the abounding abyss of the picture. Aback you watch a affairs formateb0ted for approved tv on a advanced screen, atramentous bars, accepted as windowbox bars, arise on either ancillary of the picture. One another to this is to lose some annual at the top and basal of the screen.

But one of the actualization of a wide-screen tv, is the adeptness to stretch, crop, or zoom the approved 4:3 angel so that it fills the screen, ultimately distorting the angel or accident some of its content.

Picture Quality, Audio Quality, Connectivity

Using an online arcade allegory such as Myshopping.com.au doesn't accord you the claimed feel of attractive at the tv set on the exhibit floor. However, already you've narrowed bottomward your choices according to admeasurement and architect specification, it may pay to attending at some sets so you can adjudicator annual affection for yourself.

So what makes a acceptable picture? One of the aboriginal considerations is contrast: in adjustment to acquire ablaze aciculate and ablaze pictures, the awning itself charge be dark. Screens that are two 'green' or 'grey' will not aftermath aerial analogue images. Do this with any surrounding televisions angry off and an alike ablaze in the room.

A added application is the apathy of the annual tube. If you are attractive at an LCD or Plasma screen, this is already flat, but with annual tube technology, adulate tubes aftereffect in beneath blaze from windows and lamps, and beneath actualization distortion. A collapsed tube awning will accord you a bigger examination experience.

If a tv doesn't acquire a adjust filter, its resolution will be bound to about bisected the abounding abeyant of a DVD. While adjust filters affect alone composite-video or RF connections, sets with a adjust clarify can usually accommodate all of the resolution of DVD and will not acquire confusing 'rainbow' images area awful allegory colours coincide. Adjust filters accommodate glass, digital, and 3DY, and altered types accommodate altered levels of quality, but ultimately, it's bigger to acquire one than not.

Digital and Aerial Analogue TV agency that the adeptness for a tv to affectation a accelerating browse angel is additionally agency that affects annual quality. A accelerating browse angel is a affection of agenda tv broadcasting and DVD imaging with a added film-like attending to it than accustomed video.

For optimum television watching, you charge to accede the affection of the complete too. It is now absolutely accepted for bodies to accommodate tv and hi-fi accessories into a added complete home ball system, giving a added activating home theatre experience. Agenda and Aerial Analogue tv and DVD, complete affection is agnate to that of CDs, so it makes faculty that audio connectivity allows you to affix into beleaguer complete or added hi affection complete systems. It's advantageous to analysis to see that the tv has a atomic one set of stereo audio inputs and one set of stereo audio outputs, as able-bodied as video ascribe and achievement connectors. On the ascribe side, analysis for RCA-composite, S-Video, and basic video inputs. You can frequently acquisition an added set of audio and video inputs and/or outputs on the advanced or at the ancillary of the tv, a actual acceptable area for added acting connections, such as bold consoles, web tv or video camera equipment. It can be awfully annoying if you are bound to alone access at the rear of the set, or alone one set of inputs and outputs, which can generally beggarly unplugging and reconnecting assuredly installed equipment.

If you are intending to use a set-top agenda receiver, accomplish abiding the tv has the actual connections, and that they are accordant with the receiver equipment. Application Myshopping.com.au you can chase through a abundant cardinal of brands for the actual specifications. Ideally such access should be fabricated wit1351h Fire Wire, DVI-D with HDCP or HDMI connectors.

Plasma or LCD

While there are still affection CRT televisions (tube style) actuality manufactured, the accepted television technology actuality pursued by manufacturers is Plasma Aerial Analogue or LCD (Liquid Crystal Display). The capital advantages these two technologies action includes the abate amplitude taken up (mostly in depth) for a bigger picture, beneath calefaction (and accordingly beneath electricity consumed) generated for a bigger annual and the actualization of bendability through agenda technology. But what are the differences?

In the Plasma tv over a actor tiny bottle beef are answerable with a admixture of neon and xenon, abaft which are coloured phosphors that afford ablaze aback energized. Anniversary corpuscle has a red, dejected and blooming phosphor. Aback Plasma beef are charged, they afford airy UV light. that strikes the red, blooming and dejected phosphors on the aback of the display, creating the pixels that anatomy the angel you see on the screen. LCD however, is a abeyant aqueous amid two cellophane panels that, aback activated by voltage, re-position themselves so that they either acquiesce the ablaze to canyon through the console and or block the light, a agnate action to axis on and off millions of ablaze bulbs. The ablaze antecedent is provided by beaming tubes abaft the panels. Both the lit and aphotic crystals actualize arresting pixels basic the angel on the screen.

Many absolute reviewers acquire that manufacture's blueprint of Plasma tv is not accurately portrayed. LCD appears to be both brighter and action added contrast, admitting Plasma appears to acquire college analogue colour, above examination angles and faster acknowledgment time accouterment crisper awning movement. Plasma uses added ability than LCD, but may accommodate a added theatre-like examination experience. Use Myshopping.com.au to analyze the latest brands of Plasma and LCD televisions.

Remote Controllers and Accessories

All tv sets appear with alien controls. Some appear with what's accepted as the Accepted alien control, a alien ascendancy that can ascendancy all of your media hardware.

Abounding sets do not acquire action controls on the tv itself, which could annual problems if the alien ambassador is lost. Also, not every accepted alien can ascendancy everything.

LCD TV vs. DLP TV vs. plasma TV

2008-07-09T21:43:00.000-07:00

I am leaning toward an LCD rear-projection TV because I don't want to deal with the rainbow effect of DLP rear-projection sets or the burn-in issues with plasma flat panels. I hate the fact that I have to replace a bulb every few years, but it's only a couple hundred bucks, so I guess I can stomach it. Have any strong opinions about one technology over another? Thanks.

First, you need to decide whether you want a microdisplay (also known as a rear-projection set) or a flat panel, such as a plasma or LCD TV. There are three basic types of microdisplays: LCD (liquid-crystal display), DLP (digital light processing), and LCoS (liquid crystal on silicon).

Microdisplays are thinner and lighter than the CRT rear-projection sets that are still kicking around, but for the most part, you still can't hang a microdisplay on the wall. By contrast, you can easily hang a plasma or LCD TV on the wall, but they are not widely available in very large sizes, and they cost significantly more, inch for inch. Each type of microdisplay has its pros and cons, but they all use a lamp that needs to be replaced every few years, so that shouldn't be a factor.

The rainbow effect you mention has been an issue specifically with DLP rear-projection sets, which use a color wheel to create red, green, and blue. Some viewers can see streaks of color on DLP TVs, especially when moving their eyes across the screen. Newer and faster color wheels, however, have significantly reduced the rainbow effect, and most people never see it at all. Furthermore, DLP has some performance advantages over competing technologies, including the deepest black levels of any projection technology (though LCD is coming on strong) and a 1,280x720-native-resolution chip that shows every pixel of 720p HDTV, resulting in a very sharp picture with high-definition sources.

As far as plasma TVs go, that danger of burn-in has been greatly exaggerated. Burn-in occurs when a relatively static image such as a stock ticker, a network logo, or a letterbox bar gets etched permanently onto the screen. The potential for burn-in is greatest during the first 100 or so hours of use, during which time you should keep contrast rather low (less than 50 percent) and avoid showing static images or letterbox bars on the screen for hours at a time. After this initial phase, plasma should be as durable as any television technology. Many panels also have burn-in-reduction features, such as screensavers and pixel orbiting. Under normal viewing conditions, you should have nothing to worry about. The picture quality of plasma TVs varies considerably depending on the make and model, so if you do opt for a flat panel over a microdisplay, be sure to read our hands-on product reviews before choosing.

For more on the pros and cons of different TV types, take a look at our feature "Fat or flat: 4 styles of HDTV," which is part of CNET's HDTV World. And best of luck.

ADVANTAGE AND DISADVANTAGE OF LCD TO PLASMA

2008-06-17T07:30:00.000-07:00

Flat board TVs is bright in the spot by pop civilisation. They're practiced for centerpieces successful storefront windows, video game presentation screens and miniature motion picture screens demonstrating the most recent megahits out during telecasting. At the consumer level, they are the cat’s meow – loved for their execution and envied because their elegance.

Flat board TVs is bright in the spot by pop civilisation. They're practiced for centerpieces successful storefront windows, video game presentation screens and miniature motion picture screens demonstrating the most recent megahits out during telecasting. At the consumer level, they are the cat’s meow – loved for their execution and envied because their elegance.

They are about the cutting edge from engineering science. Because of their low size, they accept the potentiality by overlooking the tv set electronics market for the next generation. And, their prices are decreasing.

Simply, not all is caviar and champagne for flat board showings. They have their contribution of issues. Below is a list of advantages and disadvantages connected with flat board displays.

ADVANTAGES

Size: The lack of width and weight is a terrific advantage across direct panorama and back end projection models. Flat board tv set* can be picked up by one person, carried between the arms like a fence post or school book and hung equivalent a impression.

Natural selection: The pick of available flat board models are overwhelming because sizes range from hand-held up to eighty-four”. Almost models will break the 20-42” range with the more commons sizes of it being 26” 32” and 42”.

* Annotation: Plasma flat board tv set* start at forty-two”. It's good to assume that all models smaller than 42” are liquid crystal display.

Aesthetic Appeal: they are astonishing how slender flat board tv set* are, especially considering what was being dealt a decade ago. These a long time are totally different. In real time, anyone can own a television none heavier than a two-liter bottle of soda. People can hang their television set on a wall like a Pablo Picasso, arrange them with a blanket or take it from room to room with little strain.

Double Use: What is an advantage for LCD is a disadvantage for plasma. LCD flat boards are great buys for people who prefer to combine television set with their personal computer as these models are specifically configured to allow computer interactivity while doubling as a tv set.

* Note: I don't recommend applying a plasma display board as a computer monitor or computer game display unit because of burn-in possibilities.

Picture Quality: Plasma is arguably the better image outside of direct view tv set*. High definition article exposed about a plasma is extraordinary. LCDs are not far behind in terms of showing high-end content, simply a few flat panel LCDs struggle in their ability to display cable and satellite programming.

* Note: Contrast ratio and black degrees on flat board displays are not comparable cathode-ray tube direct view tv set. While to the highest degree models thrive, this could comprise a disadvantage for some units.

Picture Life: Plasma and LCD tv set* had better close a minimal by thirty,000 hours up to sixty,000 hours. This means a minimum of 15 years of watching on an expected life rate a good deal longer. There is no lamp to replace, which is an advantage in long-term monetary value across back end acoustic projection models.

DISADVANTAGES

Cost: Expect to make up around $a thousand for a good thirty-two” model, $1500-2000 for a good 42” model and over $2000 for models over 50”. This approximate is on the low end, and will motley according to manufacturer and display case. For instance: A 42” Enhanced Definition television set will price considerable lower than a forty-two” High Definition model of the same specs and manufacturer. The same holds true for LCDs.

Hit or Miss: This is something that I believe mainly applies to LCD. Plasma technology are pretty straight in terms of ‘you get what you see.” Just, I do not consider LCDs are the same. In my experience of reviewing flat panel LCD television set*, a few fail to display a good picture with cable or satellite.

* Annotation: While it is hard to notice the models that are suspect in quality, I can suggest that if a price appears likewise good to be admittedly it probably is. If a flat panel television system is priced considerably below the standard cost for a model of similar economic value and they're not on sale then something is probably missing inside the unit. The missing piece could be something that bounds the characterization performance. Video game play can be dull on some LCDs, which is a answer from a low latency.

Connectivity: This is a modest disadvantage, but worth noting. Working with audio and video cables can be an issue once mounting a flat panel television system to a wall. Cables coming and becoming from a direct view and back end projection television can be hidden behind the set, but wall-mounted flat boards have nothing to hide them. Alternatively, a human are allowed to either run cables through the wall or camouflage them somehow. Then there is the issue of what to do with the cable box seat, DVD player, etcetera, while foregoing irregular entertainment center setup.

* Note: This doesn't apply to flat panel television system* being placed on a tabletop stand as the display unit will blot out cables coming and coming in the unit.

Burn-In: This only applies to plasma. Static images can leave a permanent mark on the screen. This is why nobody should use a plasma TV as a computer monitor or computer game display. Burn-in should not be a problem if the plasma display board is applied solely for watching television set and movies.

HOW LCD WORK

2008-06-11T05:02:00.000-07:00

Everyday we use item containing an LCD . They are all in between us, such as laptop computers, digital clocks and watches, microwave ovens, CD players and many other electronic devices. LCDs are common because they offer some real advantages over other display technologies.

Everyday we use item containing an LCD . They are all in between us, such as laptop computers, digital clocks and watches, microwave ovens, CD players and many other electronic devices. LCDs are common because they offer some real advantages over other display technologies.

But just what are these things called liquid crystals? The name "liquid crystal" sounds like a contradiction. We think of a crystal as a solid material like quartz, usually as hard as rock, and a liquid is obviously different. How could any material combine the two?

We learned in school that there are three common states of matter: solid, liquid or gaseous. Solids act the way they do because their molecules always maintain their orientation and stay in the same position with respect to one another. The molecules in liquids are just the opposite: They can change their orientation and move anywhere in the liquid. But there are some substances that can exist in an odd state that is sort of like a liquid and sort of like a solid. When they are in this state, their molecules tend to maintain their orientation, like the molecules in a solid, but also move around to different positions, like the molecules in a liquid. This means that liquid crystals are neither a solid nor a liquid. That's how they ended up with their seemingly contradictory name.

So, do liquid crystals act like solids or liquids or something else? It turns out that liquid crystals are closer to a liquid state than a solid. It takes a fair amount of heat to change a suitable substance from a solid into a liquid crystal, and it only takes a little more heat to turn that same liquid crystal into a real liquid. This explains why liquid crystals are very sensitive to temperature and why they are used to make thermometers and mood rings. It also explains why a laptop computer display may act funny in cold weather or during a hot day at the beach.

Should You Buy An LCD TV?

2007-08-10T01:20:00.000-07:00

One big advance in modern video technology is the LCD TV. Let face it, few homes today are without a TV set, and when the old one goes caput, they will most likely end up having to buy either an LCD or plasma TV. LCD TV's are based on the same technology as many of the things we already have in our homes, such as digital alarm clocks and calculators.

LCD TV's offer much brighter and higher contrasts than the old CRT models. LCD TV's also reduce glare on the screen, which
can be hassle on the old sets, especially if you are watching something filmed in a dark background or environment. Reducing the glare also helps to counteract the negative effect
that watching TV has on your vision, caused by eye strain. It is important to pay close attention to the dot pitch offered by
these TV's, as the lower the dot pitch, the better picture and clearer resolution you will have.

LCD TV's offer good value for your money because they tend to last a lot longer than most average TV's In testing, many have held up to over sixty thousand hours of play without
having any problems. That would equate to about fifteen to twenty years for the average TV use.

It is recommended to buy your LCD TV in a brand name, as they tend to be made with higher quality light sources, which will ensure you have high quality for the life of the set. Some
bulbs are replaceable in the event of a problem, but others can cause you to have to replace the whole set. It is important to
buy a well known brand name that has good warranty coverage on the bulbs, as you are likely to get better service should a
problem occur.

LCD TV's can be expensive, so you should definitely think about the price of the set in relation to the size of the screen. If you
desire a large screen TV, you will probably be paying quite a penny for an LCD TV that you will be satisfied with. But, on the
same thought, keep in mind that the picture quality is a lot better, meaning that you may be happy with a smaller screen if it fits your budget better.

As with any large purchase, it is a good idea to shop around and do your homework. Look at several of the same models from different dealers to negotiate the best price range. Keep
in mind to look at the customer service history of the company, as well as what warranty coverage they offer. The best price may
not always come with the best products or service. LCD TV's can be purchased online, but you should definitely make certain that
you are buying from a reputable dealer, maybe even checking with the Better Business Bureau before making your final choice. Remember, don't be afraid to ask the dealer questions about your purchase and warranty info, and if he seems unknowledgeable or reluctant to answer, take it as a good sign that you should do your shopping for your LCD TV elsewhere.

Buying a Flat LCD TV Will Cut Down on Your Electricity Bill

2007-08-10T01:10:00.000-07:00

A flat lcd tv is also great because it offers the highest resolution of any tvs, and also because it has low glare, almost no glare at all. This is because the flat profile of a flat lcd tv means that, unlike a normal curved tv screen, which catches light from any direction and sends it to you in the form of glare, a flat lcd tv is only vulnerable to light ddisturbances from a particular direction, kind of like a mirror, and unless there is a powerful light source there right in that specific spot, the flat lcd tv will not reflect it back at you.

The reason it can have a flat screen is because a flat lcd tv does not have a cathode ray tube like a normal tv. A cathode ray tube, or crt, is basically a gun that shoots out electrons at high speed at the surface of a normal tv. These electrons strike a surface that flouresces, or glows, giving you a pixel on the screen. This means that a crt tv has to have a curved screen and enough depth to position an electron gun behind it to shoot the image out of the tv. A flat lcd tv, however, because it doesn't have a crt tube, but instead a light source with polarizing filters and a thin layer of liquid crystals between, it can be very thin and efficient.

It also uses up less power by far than a normal tv so, although initially, a flat lcd tv will cost more than a normal tv, eventually, that flat lcd tv will actually save you money by cutting down on your electricity bill. But the best thing about a flat lcd tv is the clarity of the image. Because there is no distortion from the curved screen that normal tvs have, you will simply never see a clearer image than on a flat lcd tv. Additionally, flat lcd tvs have better resolution than most normal tvs and clearer defined boundaries. This will make some difference in watching normal tv programs, but is most noticeable when you look at dvd movies, which are at a higher resolution than normal tv programs. If you are a movie fan like I am, flat lcd televison is the way to go without a doubt!

LCD and Plasma TV

LCD TV
Liquid crystal display television (LCD TV) is television that uses LCD technology for its visual output. The technology used is generally TFT. In the early 2000s, LCD flat-panels captured a large part of the computer monitor market from traditional CRTs. Continuing advances in LCD TV technology enable it to compete against Plasma flat panels and rear-projection televisions (DLP, LCD, and LCoS) for large-screen HDTV.

Early LCD television had drawbacks relative to traditional visual display technologies. It displayed fast-moving action with "ghosting" and could be viewed best only when looking directly at the screen or from a slight angle. These problems have largely been overcome in recent years, and LCD televisions, along with plasma displays, have taken over the dominant market position worldwide from cathode ray displays. The LCD design has the additional advantage of being more efficient in the use of electricity than the CRT design.

For a long time it was widely believed that LCD technology was suited only to smaller sized flat-panel televisions, and could not compete with plasma technology at sizes of 40" or larger. At the time, plasma held the edge in cost and performance. This belief has been undermined by the announcements of seventh-generation panels by major manufacturers such as Samsung, Sony, LG-Philips LCD, Westinghouse Digital, and Sharp Corporation:

* In October 2004, 40" to 45" televisions were widely available, and Sharp had announced the successful manufacture of a 65" panel.
* In March 2005, Samsung announced an 82" LCD panel.[1]
* In August 2006, LG.Philips Consumer Electronics announced a 100" LCD television [2]
* In January 2007, Sharp displayed a 108" LCD panel branded under the AQUOS brand name at CES in Las Vegas.[3]

Manufacturers have announced plans to invest billions of dollars in LCD production over the next few years, with televisions expected to be a key market. (The other main market for LCD displays is in computer monitors.)

Improvements in LCD technology have narrowed the technological gap with plasmas. The lower weight, falling prices, higher available resolution which is crucial for HDTV, and lower electrical power consumption of LCDs make them competitive against plasma displays in the television set market. As of late 2006, analysts note that LCDs are overtaking plasmas, particularly in the important 40" and above segment where plasma had enjoyed strong dominance a couple of years before. [4][5]

LCD screens produce very little glare from other light sources, as opposed to shiny plasma screens.

LCD Technology

LCD technology is based on the properties of polarized light. Two thin, polarized panels sandwich a thin liquid-crystal gel that is divided into individual pixels. An X/Y grid of wires allows each pixel in the array to be activated individually. When an LCD pixel darkens, it polarizes at 90 degrees to the polarizing screens.

This cross-polarizing blocks light from passing through the LCD screen where that pixel has darkened. The pixel darkens in proportion to the voltage applied to it: for a bright detail, a low voltage is applied to the pixel; for a dark shadow area, a higher voltage is applied. LCDs are not completely opaque to light, however; some light will always go through even the blackest LCD pixels.

Plasma TV

A plasma display panel (PDP) is a type of flat panel display now commonly used for large TV displays (typically above 37" or 940 mm). Many tiny cells located between two panels of glass hold an inert mixture of noble gases (neon and xenon). The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light. It is often used in the home environment and is becoming increasingly popular in modern cultures.

Functional details

The xenon and neon gas in a plasma television is contained in hundreds of thousands of tiny cells positioned between two plates of glass. Long electrodes are also sandwiched between the glass plates, in front of and behind the cells. The address electrodes sit behind the cells, along the rear glass plate. The transparent display electrodes, which are surrounded by an insulating dielectric material and covered by a magnesium oxide protective layer, are mounted in front of the cell, along the front glass plate. Control circuitry charges the electrodes that cross paths at a cell, creating a voltage difference between front and back and causing the gas to ionize and form a plasma; as the gas ions rush to the electrodes and collide, photons are emitted.

In a monochrome plasma panel, the ionizing state can be maintained by applying a low-level voltage between all the horizontal and vertical electrodes - even after the ionizing voltage is removed. To erase a cell all voltage is removed from a pair of electrodes. This type of panel has inherent memory and does not use phosphors. A small amount of nitrogen is added to the neon to increase hysteresis.

In color panels, the back of each cell is coated with a phosphor. The ultraviolet photons emitted by the plasma excite these phosphors to give off colored light. The operation of each cell is thus comparable to that of a fluorescent lamp.

Every pixel is made up of three separate subpixel cells, each with different colored phosphors. One subpixel has a red light phosphor, one subpixel has a green light phosphor and one subpixel has a blue light phosphor. These colors blend together to create the overall color of the pixel, analogous to the "triad" of a shadow-mask CRT. By varying the pulses of current flowing through the different cells thousands of times per second, the control system can increase or decrease the intensity of each subpixel color to create billions of different combinations of red, green and blue. In this way, the control system can produce most of the visible colors. Plasma displays use the same phosphors as CRTs, which accounts for the extremely accurate color reproduction.
